Spectrum of Oral and Maxillofacial Tissue Biopsies at the Foremost Tertiary Institution in The Gambia: A Retrospective Review.

Introduction: Sub-Saharan Africa has a heavy burden of oral diseases and cancers. Also, there is a dearth of published records of oral pathology services in The Gambia. Therefore, this review aimed to determine the prevalence of biopsied oral and maxillofacial lesions in order to ascertain the uptake of oral histopathology services at the foremost tertiary institution in The Gambia.

Materials and methods: This was a retrospective study performed at the Pathology Department of Edward Francis Small Teaching Hospital. Reports of all oral and maxillofacial biopsies submitted for the period 2012 to 2021 were reviewed and data were extracted. Descriptive analysis was done using SPSS software, version 26.

Results: Total number of biopsy reports was 158 representing 0.02% over the study period. The mean age of patients was 34.3 ± 19.7 years, the 3rd decade was the peak age of presentation and male-to-female ratio was 1:1.6. Majority (65/41.1%) of the cases were benign neoplastic lesions, and the mandible was the most (21/13.3%) common site of biopsy. Reactive lesions were the predominant (34/21.5%) group and squamous cell carcinoma had the highest (24/15.3%) number of lesions while odontogenic tumours constituted six cases only (3.8%).

Conclusion: The findings of this study showed low uptake of oral histopathology services while biopsied oral and maxillofacial lesions were prevalent in female patients in the third decade of life. Also, the mandible was the most affected site whereas benign neoplastic diagnoses were most common. However, this study recorded a higher proportion of malignancies than some previous studies.
