[1-6] Necrotizing fasciitis has been referred to by many different names such as hospital gangrene, flesh eating disease, streptococcal hemolytic gangrene, synergistic necrotizing cellulitis, and Fournier's gangrene when it involved the perineum. [1,3,7,8] It was described by Joseph Jones in 1871 during the American Civil war but was first described as necrotizing fasciitis in 1952 by B. Wilson. [1,3,7-11] When this condition occurs in the head and neck region, it is referred to as cervicofacial necrotizing fasciitis (CNF). CNF is an uncommon infection and majority of cases are sequel to odontogenic infections. [1,10] Early recognition with prompt intervention is paramount to the management of CNF to prevent serious morbidity or mortality. [1,2] Its management involves patient resuscitation, antibiotic therapy, removal of etiological factor (where identified), extensive serial surgical debridement, and subsequent reconstruction. [1] Previous reports of this infection in socioeconomically challenged society like ours, are retrospective in nature and details such as the extent of wound defect, whether management was done on in-patient or outpatient basis, duration of hospital admission and the nature of complications encountered and not just the mortality rate are lacking. [11,12] This study aimed at prospectively documenting the presentation, management, challenges, and outcome of management of CNF in our institution. MAterIAls And Methods Information on age, gender, socioeconomic status, duration of symptoms before presentation, background systemic condition, site of infection, etiology of infection, causative organism (s), antibiotic therapy, span of defect, duration of hospital stay, days to achieve wound closure and complications was collated for all patients who presented at the Department of Oral and

These were made up of 44 (3,6 %) out of 1,210 males and 70 (5,4%) out of 1,296 females giving a male to female ratio of 2:3 (Table I). The ages of the subjects with tori ranged from 7 to 62 years with a mean of 26.6 (±10) years while the median was 24 years. Majority (68 %) of the subjects were in the age group 21-40 years. The age of the male subjects ranged from 7 to 55 years (mean 26.8 ± 11.3 years) while those of the female subjects ranged from 15 to 62 years (mean 26.5 ± 9.3 years). There was no significant difference in mean age at 5 % level (P < 0.05). Torus Palatinus Out of 2,506 patients 49 (2 %) had T.P. and were made up of 18 (1.5 %) males and 31 (2.4 %) females. The males to female ratio was 3:5. The age range was 7 to 55 years while the mean age for males was 22.5 (± 11.3) years and for females 24.3 (± 6.6) years. Torus mandibularis (T.M.) Out of the 2,506 subjects 79 (3.2 %) had torus mandibularis. They were made up of 29 (2.4 %) males and 50 (3.9 %) females, giving a male to female ratio of 3:5.

Males were more involved in midfacial fractures than females (M : F of 7.6 : 1). Most of the fractures occurred in the 21-30 year age group. Road traffic accidents were responsible for the majority of the fractures (78.7%). The zygomatic complex/arch was the most frequently involved area (63.0%) while the most common treatment was open reduction of zygomatic complex/arch fractures with trans-osseous wiring of suture lines (29.13%).

This is a report of a 42 year old man with a recurrent mandibular neoplasm who had repeated surgical interventions. Clinical and radiographic examinations were not significantly different from other regular variants of ameloblastoma. Microscopic examination however revealed islands of cuboidal and columnar cells arranged in a pallisaded pattern with a central area of squamous metaplasia and stellate reticulum-like cells. There were multiple vascular channels containing red blood cells within the stellate reticulum-like areas. Surgical resection of the mandibular mass was done with immediate reconstruction. It may be concluded that repeated surgical interventions may be a possible etiology for the development of hemangiomatous ameleblastoma.

Pederson index was used to predict the difficulty of 79 cases of impacted mandibular third molar extractions. The predictions were compared with actual surgical difficulty determined by operation time. The reproducibility as well as the reliability of the index was determined. The index was found to be highly reproducible (P=0.00). The sensitivity and specificity were 94.9% and 45% respectively. The Positive predictive value (PPV) was 67.2% and the negative predictive value was 90% while the accuracy was 69.6%. The Pederson index though reproducible is not a reliable instrument for predicting surgical difficulty of third molar surgery when compared with actual surgical difficulty as determined by the operation time. There is a definite need to derive an index that could be used for preoperative prediction of d...

More than 50% of the children were males. The dominant age group was 0-4 years and the most common aetiology was road traffic accident. Jaw fractures and soft tissue lacerations were the commonest presentation and fractured limbs were the most common concomitant injuries. The need to abolish street trading among children is emphasised as this has been recognised to expose children to hazards of the road since most of the children were pedestrians.

Its epidemiology, clinical and histologic configurations are replete in local and international literature, but data about its gross surgical patterns and treatment outcome in Nigeria is sparse. We therefore describe the clinical, gross surgical configuration, histopathologic features and the outcome of management seen at a Nigerian tertiary hospital. Records of all histologically diagnosed Ameloblastoma from January 2000 to December 2011 at the University College Hospital, Ibadan, Nigeria, were retrieved from the departments of Oral and Maxillofacial Surgery and Oral Pathology. Patients' biodata, clinical, radiographical, gross surgical and histological features of the tumours, type of treatment, mode of jaw reconstruction and post-surgical follow up period data were documented. One hundred and sixty-three ameloblastomas were diagnosed during the study perio...

Methods of reconstruction included non vascularised iliac bone anchored with either stainless steel wire (NVIBw) [n=38] or titanium plate (NVIBp) [n=9], titanium reconstruction plate [n=4] Steinman pin [n=12], rib graft [1] and acrylic plate temporisation [n=1]. The findings showed that titanium plate and...

Pederson index was used to predict the difficulty of 79 cases of impacted mandibular third molar extractions. The predictions were compared with actual surgical difficulty determined by operation time. The reproducibility as well as the reliability of the index was determined. The index was found to be highly reproducible (P=0.00). The sensitivity and specificity were 94.9% and 45% respectively. The Positive predictive value (PPV) was 67.2% and the negative predictive value was 90% while the accuracy was 69.6%. The Pederson index though reproducible is not a reliable instrument for predicting surgical difficulty of third molar surgery when compared with actual surgical difficulty as determined by the operation time. There is a definite need to derive an index that could be used for preoperative prediction of d...

More than 50% of the children were males. The dominant age group was 0-4 years and the most common aetiology was road traffic accident. Jaw fractures and soft tissue lacerations were the commonest presentation and fractured limbs were the most common concomitant injuries. The need to abolish street trading among children is emphasised as this has been recognised to expose children to hazards of the road since most of the children were pedestrians.

Its epidemiology, clinical and histologic configurations are replete in local and international literature, but data about its gross surgical patterns and treatment outcome in Nigeria is sparse. We therefore describe the clinical, gross surgical configuration, histopathologic features and the outcome of management seen at a Nigerian tertiary hospital. Records of all histologically diagnosed Ameloblastoma from January 2000 to December 2011 at the University College Hospital, Ibadan, Nigeria, were retrieved from the departments of Oral and Maxillofacial Surgery and Oral Pathology. Patients' biodata, clinical, radiographical, gross surgical and histological features of the tumours, type of treatment, mode of jaw reconstruction and post-surgical follow up period data were documented. One hundred and sixty-three ameloblastomas were diagnosed during the study perio...
