W. GS, F.G. M, M. OT, A. WK. "Combined Modality Approach in the management of Oral and Circumoral Haemangiomas with emphasis on the use of Absolute Ethyl Alcohol.". 2011. AbstractWebsite

Although various modalities of treatment of haemangiomas including embolic therapy have been proposed, consideration of cost and technological requirements suggest that cheaper methods with less technological re-quirements need to be developed for use particularly in developing countries. The study objective was to de¬scribe the pattern of circumoral haemangiomas and explore the possible role of absolute ethyl alcohol in their management. It was a prospective study using hospital based study group at the University of Nairobi teaching and referral Dental Hospital. Of the 25 cases (24 females, 1 male) on follow-up, 68% had carvemous while 20% had capillary haemangiomas. The majority of the haem angiomas ranged in size from 2cm 2 - 31.5cm2. The lower lip was the most frequently affected (52%). None of the cases underwent spontaneous involution even after 10 years of follow-up. After intra lesions administration of alcohol, 3 cases of carvenous haeman¬gioma measuring 2cm2 and none of the capillary type underwent complete resolution. Other benefits of ethyl alcohol included better localization of the lesion and negligible intra and post operative haemorrhage for cases requiring surgery. Although pain and swelling for a few days were recorded in all cases and superficial tissue necrosis in two cases, there were no major alcohol-related complications. Therefore, Intra-lesion administra¬tion of absolute ethyl alcohol appears to be effective adjuvant to surgery and in addition may result in com¬plete resolution of small cavernous types of lesion. Spontaneous resolution of haemangiomas is not common in our set-up.

OBJECTIVE: To determine the pattern and characteristics of patients admitted with firearm injuries (FAIs) and establish the morbidity and mortality associated with these injuries. DESIGN: Retrospective cross-sectional study. SETTING: Kenyatta National Hospital (KNH), January 2004 to December 2005. SUBJECTS: All patients admitted with physically evident firearm injury. RESULTS: There were a total of 717 patients recorded with FAIs constituting 0.6% of the total number of patients seen in the casualty. Of these, 421 (58.7%) were admitted and treated as in- patients. A firearm was used in 6.7% of the 6300 assault cases recorded in 2004 and in 9.7% of the 3079 cases recorded in 2005. The increase from 6.7% in 2004 to 9.7% in 2005 was statistically significant (p < 0.05). There were 370 (87.9%) males and 49 (11.6%) females giving a male to female ratio of 7.5:1. The mean age was 29.7 +/- 10.9 years with a range of 3 to 66 years. At least 262 (62.2%) of the 421 admitted FAI casualties were treated under general anaesthesia (GA). The average duration of operation per patient was 2 +/- 1.5 hours. CONCLUSION: FAIs are on the increase and affect all age groups but is largely a disease of a young male adult in the 3rd and 4th decade of life. Mortality is higher with increasing age while female victims are fewer but on average six years younger than males. The lower extremities are the commonest target among the survivors. However, abdominal wounds tend to be the most lethal, accounting for greater mortality.

BACKGROUND: Road Traffic Accidents (RTAs) are a major cause of morbidity and mortality in Kenya. Victims may suffer multiple injuries including maxillofacial injuries. In most developing countries RTAs are the leading cause of maxillofacial injuries. In an attempt to reduce RTAs, the government of Kenya has enacted a legislation requiring mandatory fitting of speed governors and safety belts by passenger service vehicles. OBJECTIVE: To describe the characteristics and pattern of maxillofacial and associated injuries sustained in road traffic accidents. DESIGN: A cross-sectional study. SETTING: Kenyatta National Hospital (KNH). SUBJECTS: All patients involved in RTAs brought to casualty and the dental department of KNH as well as accident victims admitted to the KNH mortuary over a four- month period from September 2004 to December 2004. RESULTS: Four hundred and thirteen (85.7%) had non-fatal injuries whereas 69 (14.3%) had sustained fatal injuries. Males in the 21-30-year age group were the most affected. Most accidents occurred during weekends with pedestrians being the leading casualties in 59.5% and 71.4% of non-fatal and fatal cases respectively. Most accidents were caused by passenger service vehicles (matatus) which were responsible for 62% and 40.6% of non-fatal and fatal injuries respectively. Non-use of safety belts was reported in 56.6% of the cases who suffered non-fatal injuries. In the non-fatal category 89.6% of the casualties had soft tissue injuries (STIs) involving the craniofacial region with facial cuts being the majority (69.2%). Two hundred and seventy three (66.1%) incidents of other STIs than those of the head region were noted, the lower limbs accounting for 45.4% of these. Only 5.1% of the casualties with non-fatal injuries had fractures involving the maxillofacial skeleton. Skeletal injuries other than those involving the maxillofacial region were found in 142 (34.1%) incidents. In the fatal category head injury alone was the leading cause of death accounting for 37.7% of the cases followed by head and chest injuries combined which were responsible for 13% of the cases. CONCLUSION: Injuries to the maxillofacial skeleton appear to be uncommon in this series. Pedestrians in their third decade of life are most affected with passenger service vehicles being responsible in the majority of the cases. RECOMMENDATIONS: Interventional programmes targeting pedestrians and those in the third and fourth decades of life should be enacted.

OBJECTIVE: To determine the range of ablative surgery and rehabilitative procedures performed on maxillofacial structures. DESIGN: A retrospective descriptive study. SETTING: University of Nairobi Dental Teaching Hospital. SUBJECTS: Patients operated on at the institutions theatre, and followed up at the University of Nairobi Dental Teaching Hospital Oral Surgery Outpatient Clinic during the period February 1996, August 1998. RESULTS: Forty four patients underwent ablative surgery during the study period. Complete records were available for 38 patients, 27 females and 11 males aged 10 to 79 years (mean 32.6 years). Surgical procedures performed included: partial mandibulectomy, marginal mandibular resection, subtotal maxillectomy, sequestrectomy and enucleation. Six (15.8%) patients who underwent mandibular resection had rigid bone plating. Five (13.2%) patients who had maxillary involvement were given surgical obturators post-operatively with one receiving a complete denture after full recovery. A total of 22 (57.9%) patients who would have reaped benefits from prostheses therapy received none. Individual patient follow-up periods ranged from seven days for two patients who had cyst enucleation to two years for three cases with ameloblastoma, and two cases with squamous cell carcinoma. CONCLUSION: It is concluded that prosthetic rehabilitation of patients undergoing extensive surgery at the University of Nairobi Dental Teaching Hospital is largely inadequate.

Although military conflicts are common on the African continent, there is a paucity of data regarding bomb-blast injuries in this region and in Kenya in particular.  This paper describes the pattern of maxillofacial injuries sustained after the august 1998 bomb blast that occurred in Nairobi, Kenya.  A retrospective cross-sectional study was carried out using hospital-based records of 290 bomb-blast survivors admitted at the Kenyatta national Referral and Teaching Hospital in Nairobi.  Using a self-designed form to record information about variables such as the sex and age of the survivors and type of location of soft and hard tissue injuries, it was found that of the 290 bomb-blast survivors, 78% had sustained one or more maxillofacial injuries.  Soft-tissue injuries (cuts, lacerations or bruises) were the most common, constituting 61.3% of all injuries in the maxillofacial region: 27.6% had severe eye injuries, while 1.4% had fractures in the cranio-facial region.  This paper concludes that the effective management of bomb-blast injuries as well as those caused by other types of disaster requires a multidisciplinary approach.  The high percentage of maxillofacial injuries confirm that maxillofacial surgeons should form an integral part of this multidisciplinary team.

Although multiple supernumerary teeth without any associated syndromes are rare, their occurrence can create a variety of clinical problems such as derangement of the occlusion, prevention of eruption of permanent teeth, damage to adjacent teeth, cystic degeneration and root resorption. Hence, clinical and radiographic evaluation of patients should always be thorough in order to detect their presence. Furthermore, because the clinical management of multiple supernumerary teeth poses a great challenge to clinicians, timely, appropriate consultation and interdisciplinary approach to treatment is extremely important. We report two cases, a 14 year-old boy with eight and a 13-year-old girl with seven supernumerary teeth not associated with syndromes. In the boy, the teeth were bilaterally distributed in all quadrants in the premolar regions, and in the girl they were distributed bilaterally in the premolar regions in the mandible and bilaterally distal to the upper third molars. The clinical implications and management are discussed.

Normal anatomical values regarding size and patterns of maxillary sinuses often refer to standards obtained in population groups in western countries, This study aims to deduce normal radiographic values of maxillary sinus size and patterns of frontal and maxillary sizes in Kenyan adults. Standard occipitomental radiographs of patients referred to the University of Nairobi Dental Hospital formed the material of study and analysis included mean height and width of maxillary sinuses.

Purpose:

Although the incidence of maxillofacial injuries caused by wildlife in Kenya is not known, it is estimated to be 2 to 5%. In Kenya, the tourism industry is the main source of foreign revenue. Therefore, the country invests a substantial amount of money in promoting tourism and improvement of the country's parks/game reserves. On rare occasions, some of the wild animals will leave their natural habitat, within the confines of the national parks, and pose a threat to the people living in the neighbourhood. The animals particularly implicated include lions, buffalos, hippopotamus, leopards and hyenas.

Material and method:

Within a period of 4 years, seven patients aged between 22 and 35 years, mean age 28 years, were referred for management of overwhelming maxillofacial injuries caused by wild animals. The injuries involved the upper face, midface and lower face. The midface was more involved than the rest of the face. The most common injuries diagnosed were crushing and mutilation types of injuries. Apart from the oro-maxillofacial region, upper extremities were commonly involved.

Results:

The duration before presentation ranged from 6 hours to 6 days. One of the patients, Female aged 35 years, was evacuated late and presented with severe tissue necrosis and irreversible damage of the right eyeball. Management comprised of surgical toilet, debridement and primary repair or crushing injuries. Mutilated injuries required repeated debridement and staged reconstruction of the defects. The latter injuries were particularly caused by lions and leopards and secondarily hyenas. Tetanus toxoid was administered to all the patients, whereas antirabies vaccination was given only to patients with mutilation injuries.

Conclusions:

In assessment of patients with severe maxillofacial injuries caused by wild animals, a similar approach to that of patients with multiple injuries caused by motor vehicle accidents should be employed. Meticulous examination, life support measures and relevant surgical procedures should be instituted immediately to minimize morbidity and mortality arising from these injuries.

Osteosarcoma (OS) is a highly malignant tumour and is the most common primary neoplasm of bone; although rare, especially in the maxillofacial skeleton. This article presents 14 Kenyan cases of OS of the maxillofacial bones seen between January 1991 and July 1997: 11 in the mandible, two in the maxilla and one in the right zygomatic arch. Patients ranged in age from one week to 50 years (Mean = 29.7), with an equal gender distribution. While pain and rapid swelling were the commonest clinical features, the radiographic and histopathological characteristics were as varied as has been described elsewhere. Generally, effective management of most of the cases was poor due to late presentation for treatment.

We demonstrate that a mutation in the homeobox gene, MSX1, causes a common developmental anomaly, familial tooth agenesis. Genetic linkage analyses in a family with autosomal dominant agenesis of second premolars and third molars identified a locus on chromosome 4p, where the MSX1 gene resides. Sequence analyses demonstrated an Arg31Pro missense mutation in the homeodomain of MSX1 in all affected family members. Arg 31 is a highly conserved homeodomain residue that interacts with the ribose phosphate backbone of target DNA. We propose that the Arg31 Pro mutatrion comprises MSX1 interactions, and suggest that MSX1 functions are critical for normal development of specific human teeth.

Among the 803 individual examined, the following prevalence of lesions was observed: leukoedema (26%), melanosis (12.7%), leukoplakia (10.6%), palatal keratosis (6.4%), frictional keratosis (5.5%), pre-leukoplakia (4.1%), borderline leukoplakia (2.4%), cheek/lip biting (1.3%), and snuff dippers lesion (0.4%), 48.6% of the subjects had at least one of these lesions. Statistically significant preponderance was demonstrated for oral leukoplakia, palatal keratosis, leukoedema and frictional keratosis among males and melanosis among females. With regard to clinical classification of oral leukoplakia, the prevalence was 10% for homogeneous and 0.6% for non-homogeneous lesions. On the basis of aetiological classification, the prevalence was 8.3% for tobacco associated and 2.2% for idiopathic leukoplakia, 22.5% of leukoplakia lesions biopsied had evidence of epithelial dysplasia. In view of the premalignant potential of oral leukoplakia, our findings suggest a need for greater attention towards prevention and control of this lesion in the study community.

Early detection and immediate psychological support by excision and reconstruction of ankylosed TMJ with a costochondral graft, improves patient comfort and rehabilitation when used as a planned part of a comprehensive therapy. This paper questions prior varied opinions and discusses scientific baseline considerations in management of long standing TMJ ankylosis in children in relatively affordable circumstances.

Among the 803 individual examined, the following prevalence of lesions was observed: leukoedema (26%), melanosis (12.7%), leukoplakia (10.6%), palatal keratosis (6.4%), frictional keratosis (5.5%), pre-leukoplakia (4.1%), borderline leukoplakia (2.4%), cheek/lip biting (1.3%), and snuff dippers lesion (0.4%), 48.6% of the subjects had at least one of these lesions. Statistically significant preponderance was demonstrated for oral leukoplakia, palatal keratosis, leukoedema and frictional keratosis among males and melanosis among females. With regard to clinical classification of oral leukoplakia, the prevalence was 10% for homogeneous and 0.6% for non-homogeneous lesions. On the basis of aetiological classification, the prevalence was 8.3% for tobacco associated and 2.2% for idiopathic leukoplakia, 22.5% of leukoplakia lesions biopsied had evidence of epithelial dysplasia.

Although great advances in treatment of oro-facial clefts have been made over the past 50 years; in developing countries, due to social stigmas and unavailability of specialised medical facilities and personnel to the majority of the population, there is an increasing incidence of patients coming late for repair of oro-facial clefts. This presents a challenge to both plastic, oral surgeons and associated specialists. The aim of the present article is to demonstrate, in the form of a case report, an alternative surgical technique that has be successful in 8 cases for the late repair of severe bilateral cleft palate utilizing locally available and affordable materials. The objective of managing patients with cleft palate in developing countries is to provide the best repair and rehabilitation with as few operations and in-patient care as possible due to limited financial resources experienced by the majority of in-patients. A multidisciplinary approach to the management of oro-facial clefts is emphasised.

Loss of 1st and 2nd molars among adolescents due to dental caries is not uncommon in developing countries. Whilst their replacement is indicated, conventional methods of treatment, namely, bridging and dentures are in most cases inaccessible because of prohibitive cost. Given that it is in the same age group that diagnosis of unfavourably embedded wisdom teeth becomes feasible, autotransplantation of the latter to replace the unsalvageable 1st and 2nd molars could be an alternative treatment. Available literature suggests a success rate of over 82% based on follow-up studies of over ten years. Observations at the Dental School Clinic of the University of Nairobi, Kenya, indicate that the time it takes the transplant to 'take' and assume its functional position is 4 to 8 weeks and 2.5 to 3.5 months respectively. Since the method is relatively straightforward, we are of the view that training undergraduates and practising dental surgeons in this technique should enhance utilisation of otherwise "useless" teeth to replace the lost 1st and 2nd molars in occlusal rehabilitation.

This study was done to determine the nature of utilization of dental auxiliaries and medical emergencies in private dental surgeries in Kenya. A self administering questionnaire with pre-paid postage was mailed to 138 dentists. 27.5% responded. 81.6% used dental auxiliaries and the main reason was to improve efficiency in managing patients. 93.5% of the auxiliaries were on job trained secondary school graduates. 63.2% of the respondents delegated duties which were mainly non-clinical. 26.3% did not delegate any duties. In a descending order, the reasons for non delegation were: that it would be risky to patients, not allowed by law, they did not find it necessary and that auxiliaries were not held responsible if something went wrong. The main duties delegated to the auxiliaries were cleaning of instruments and sterilization, mixing of restorative materials and preparing amalgam. Delegation was done primarily based on auxiliaries capability to perform the procedure and meet the set standards. 57.9% indicated that they rarely encountered medical emergencies. Syncope was the commonest emergency encountered. 72.7% indicated that auxiliaries could not handle medical emergencies because they were not trained. It is concluded that most dentists did not delegate clinical duties to dental auxiliaries and medical emergencies were rare.

This study was done as part of a WHO international survey of orofacial mutilations and NOMA cases referred to out-patient clinic and care centers in 1992. Files of 16,000 patients who were treated at the Dental Unit of Kenyatta National Hospital (KNH) were scrutinized for the occurrence of NOMA and other ulcerative oral lesions. Of these, 30% had acute necrotizing ulcerative gingivitis with a male to female ratio of 5:1. 25% had aphthous ulcers with a male to female ratio of 3:2. Equal numbers of patients (10%) had angular cheilitis, aspirin burn and oral candidiasis. Similarly, equal numbers of patients (5%) had NOMA, atypical ulceration and radiotherapy induced ulceration. It was concluded that NOMA and other ulcerative oral lesions were rare among the patients who were treated at the Dental Unit of KNH.

Cancrum oris cases are occasionally treated in various hospitals in Kenya. Despite this, only one case has been reported in literature. Besides, no epidemiological or treatment studies of cancrum oris has been carried out in Kenya. We report an unusual case of a 17 year old Kenyan female with oral cutaneous fistula and tissue atrophy on the left cheek following cancrum oris infection in childhood. Since most cancrum oris cases are a sequela of acute necrotizing gingivitis (ANG), prevention of cancrum oris can be achieved by early and prompt remedial measures once a diagnosis of ANG is established. Failure to do this might lead to cancrum oris with its attendant disfiguring complications some of which might be impossible to treat in developing countries where the requisite personnel is lacking or inadequate.

Given that it is in the same age group that diagnosis of unfavourably embedded wisdom teeth becomes feasible, autotransplantation of the latter to replace the unsalvageable 1st and 2nd molars could be an alternative treatment. Available literature suggests a success rate of over 82% based on follow-up studies of over ten years. Observations at the Dental School Clinic of the University of Nairobi, Kenya, indicate that the time it takes the transplant to 'take' and assume its functional position is 4 to 8 weeks and 2.5 to 3.5 months respectively. Since the method is relatively straightforward, we are of the view that training undergraduates and practising dental surgeons in this technique should enhance utilisation of otherwise "useless" teeth to replace the lost 1st and 2nd molars in occlusal rehabilitation.

Radiation doses received by patients during dental x-ray examinations were measured in 95 patients referred to the X-ray Department of the Teaching Dental Hospital, University of Nairobi. The mean skin dose for single periapical films was 5.96 milligray (596 millirads) with the bitewing view recording a mean dose of 5.57 milligray (mGy). During a 14-film full-mouth periapical survey, mean doses ranged from 10.3-16.2 mGy for the upper jaw and 10.1-13.5 mGy for the lower jaw, respectively, depending on the region of dentition. In these full-mouth examinations, the distribution of skin dose over different parts of the dentition showed a characteristic pattern which may be explained by the overlap of radiation fields in the aggregated series of exposure. Orthopantomography recorded lower mean skin doses of 3.26 mGy in the molar region and 2.67 mGy at the posterior midline at the level of the 2nd cervical vertebra. The relative merits of intra-oral radiography versus orthopantomography are discussed, with radiation dosage as one of the factors to be considered. Some observations are made on measures to reduce patient dose.

A case of an ameloblastoma diagnosed about 3 1/2 years after removal of an impacted mandibular 3rd molar is presented. The pre-operative radiographs, though poor in quality, showed an ill-defined radiolucency in relation to the tooth. This feature was not apparent to the examiners at the time of first presentation. Despite unfavourable working conditions in developing countries, a high level of suspicion should be maintained to avoid serious sequelae at a later stage.

There is no uniformity in the role of different aetiologic factors in mandibular fractures in different cities of the world. Cultural and socioeconomic factors appear to have important contribution to the aetiologies. The condyle and the angle-body regions are most commonly fractured. There is no obvious relationship between aetiology and the site of fracture. Structural considerations suggest that differences between dentate (open section structure) and non dentate (closed section structure) regions are important determinants of fracture sites. Some modifications of standard teaching materials are recommended.

There is no obvious relationship between aetiology and the site of fracture. Structural considerations suggest that differences between dentate (open section structure) and non dentate (closed section structure) regions are important determinants of fracture sites. Some modifications of standard teaching materials are recommended.

Analysis of 355 cases with fractures of the mandible indicated that 74.9% of the cases were due to interpersonal violence and 13.8% were caused by road traffic accidents. The men to women ratio was 8.4:1 and 75.5% of the fracture cases had single fractures while 24.5% had multiple fractures. In cases with a single fracture, the most commonly involved mandibular site was the body (42.2%). The angle of mandible was most frequently fractured (50.5%) in cases with multiple fractures.
