IntroductionThis retrospective study analysed head and neck malignancies seen over a 19-year period at the University College Hospital, Ibadan.MethodologyOne thousand, one hundred and ninety two patients with head and neck malignancies were analysed according to age, gender, topography and histology.ResultsThere was an annual hospital frequency of 62 cases per year. The overall mean age for these malignancies was 43.9 (SD ± 19.3) years. The lesions from the respiratory tract were the most frequent (43.2%) of all cases. The palate was the most frequent intra-oral site (13.8%). Epithelial malignancies constituted 73.4% of all cases with a male: female ratio of 2:1, a mean age of 48.1 (SD ± 17.5) years and were mostly located in the larynx (19.7%). Lymphomas constituted 17.5% of all head and neck cancers with a male: female ratio of 1.6:1, a mean age of 35.1 (SD ± 20.6) years and nodal involvement (39.7%) was most common. Sarcomas constituted 8.9% of all malignancies with a male: female ratio of 1.5:1, mean age of 27.1 (SD ± 16.7) years and the maxillofacial bones (42.5%) were most commonly involved. Neuroendocrine malignancies accounted for 0.2% of head and neck malignancies with a male: female ratio of 1:1, a mean age of 28.5 (SD ± 6.4) years and both cases involved the nose.ConclusionThis study has further confirmed that carcinomas remain the most frequent cancers of the head and neck region in south-western Nigeria.

A prospective study of 159 patients seen with maxillofacial fractures as a result of road traffic accidents in a Nigerian inner city was performed. The male to female ratio was 2.9:1 and the dominant age group was 21-30 years. Occupants of commercial vehicles were the ones mostly involved; involvement of rear seat occupants was high. Increased numbers of patients were seen on Saturdays and in the month of June. This study substantiates the fact that there is added risk of sustaining facial fractures during the rainy and leisure periods. Therefore, there is a need to stress the importance of common restraint devices and good road habits during these 'high risk' periods to reduce the incidence of maxillofacial fractures due to the road traffic accidents.
