title: Maxillofacial tumors and tumor-like lesions in a Nigerian teaching hospital: an eleven year retrospective analysis.
abstract: BACKGROUND
  This paper reviews the types, prevalence and demographic distribution of maxillofacial tumors, cysts and tumor-like lesions in a Nigerian population.
  
  
  METHODS
  A retrospective analysis of the medical records and histological reports of patients with oral and maxillofacial tumors and cystic lesions who presented to the Maxillofacial Unit of our institution over an eleven year period was undertaken. Information on demographics, histological diagnosis and clinical presentation were obtained and analyzed. A p value of less than 0.05 was considered significant.
  
  
  RESULTS
  A total o:f 146 patients, aged 5-70 years (mean 30.5± 12.9) were seen over the period of study. There were 96 males (65.8%) and 50 females (34.2%) giving a male to female ratio of almost 2:1. Benign tumors accounted for 124, 86.3% and malignant tumors (22, 13.7%). Ameloblastoma was the most prevalent benign tumor observed (53, 36.3%) while squamous cell carcinoma was the most common malignant tumor. The peak age of ameloblastoma was the fourth decade and squamous cell carcinomas the sixth and seventh decades of life. Jaw swellings were the most common presentation (98, 67.1%), followed by pain (23, 15.9). The duration of symptoms on presentation ranged from 1 to 96 months (mean 23.32 ±15.72) and this was not different for malignant or benign tumors (P=0.886).
  
  
  CONCLUSIONS
  Late presentation still remains the main challenging factor in the early detection and management of maxillofacial tumors in our environment. More awareness campaign is necessary, especially at the primary health care level, to educate the populace on the need for early presentation at treatment centers.
