Objectives: There is a dearth in literature on the spectrum of Otorhinolaryngology (ORL) disorders in countries such as Nigeria despite its importance in making health care policies.

Methods: We conducted a ten-year retrospective study of all ORL biopsies sent to our laboratory from January 2006 to December 2015. The slides were retrieved and re-examined microscopically. Special stains were performed in cases suspicious of fungal or tuberculous lesions. The age, sex, anatomical locations, and histological diagnoses were all recorded in pre-designed data forms. All the data were analyzed using the Statistical Package for Social Sciences (SPSS) version 18.

Results: There were 572 biopsies received out of 21,633 samples during the period representing 2.64% of the total biopsies. The age range in this study was between 4 months and 87 years. The mean, mode and median ages were 21.19 ±22.10, 10 and 2 years respectively. There were 356 (62.2%) males and 216 (37.8%) females with a male to female ratio of approximately 1.6: 1. The most common site of biopsy was the throat (72.6%) while the least was in the ear (4.5%). Follicular hyperplasia was the most common diagnosis (63.1%). Nasal, benign polyps and carcinomas accounted for 14.7%, 10.7% and 8.6% respectively.

Conclusion: Follicular hyperplasia was the most common diagnosis, while throat was the most common region of biopsy. Carcinoma peaked in the 6th decade.
