Objective: This is to profile the problems of late presentation and possible behavioral differences of the tympanomastoid cancers seen within 5 years in our population. It also identifies the need to study the aetiological role of cigarette smoking.

Methods: This is a retrospective study of the case record.

Results: Eleven cases were seen, The ages ranged between 3 and 56 years. The patients presented within 2 14 months of onset of disease. Possible aetiological factors include chronic suppurative otitis media in 3(27.3%) and cigarette smoking in 4(36%). Using the Pittsburgh staging, the clinical features at presentation was T4 tumour in 10/11(91%) with involvement of the middle ear in 9, dura in 2 and infratemporal soft tissue in 4, One patient had T1 tumour. The histological type was squamous cell carcinoma in 7(64%), rhabdomyosarcoma 2 (18%) and mucoepidermoid carcinoma in 2(18%). The patients were treated with combined surgery and radiotherapy. Three (27%) have died within 2 years. CONCLUSION:The young age of patients and prominence of smoking are at variance with the cauccasians. Early detection appear the only strategy available to reducing the morbidity and mortality, however, further study may clarify the aetiological of cigarette smoking.
