Prevalence of Oral Lesions and Maxillofacial Biopsy in a Stomatology Service: Retrospective Study of 2078 Cases

Abstract

The clinical examination and radiographs provide a provisional clinical diagnosis that should be confirmed by biopsy in many cases. Oral and maxillofacial lesions biopsied in Brazilian patients treated at the stomatology clinic from 2000 to 2012 were surveyed. Materials and Methods: The medical records of 2078 patients with a histopathological diagnosis of oral cavity and maxillofacial lesions were studied. The patient's clinical data were registered and evaluated retrospectively. Results: The histological findings were varied, with a total of 108 different diagnoses. Of the lesions biopsied, 104 (7.9%) were squamous cell carcinomas. The most frequent lesions biopsied were non-neoplastic proliferative processes, including in particular inflammatory fibrous hyperplasia (33.7%), pyogenic granuloma (4.5%), and peripheral ossifying fibroma (1.0%). Mucus extravasation/retention phenomenon (7.0%) and lichen planus (4.2%) were also common in our series. Conclusion: The frequency of oromaxillofacial complex lesions susceptible to histopathology study was similar to the figures reported elsewhere in the literature.
