ABSTRACT

ABSTRACT Background: Tumours of odontogenic origin (OTs) resulting from epithelial and mesenchymal elements that are part of the tooth-forming apparatus must be considered as a differential diagnosis when analysing jaw lesions. They may be cystic, myxomatous or sometimes have a mixture of cystic and solid areas. Objective: To analyse the OTs seen at the Maxillofacial Surgery Department, Ahmadu Bello University Teaching Hospital, Zaria, Nigeria, between 2001 and 2013 based on the World Health Organization 's 2005 classification of OTs. Methods: A retrospective search and analysis was conducted of the medical records of all patients with a histopathologic diagnosis of orofacial tumours and tumour-like lesions seen at the Maxillofacial Surgery Department, Ahmadu Bello University Teaching Hospital, Zaria, Nigeria, from 2001 to 2013. Results: Odontogenic tumours constituted 179 (15.3%) cases out of a total of 1170 orofacial tumours and tumour-like lesions seen within the study period. The 179 OTs were found in 101 (56.4%) males and 78 (43.6%) females, giving a male to female ratio of 1.3:1. The ages of the patients ranged from 12 to 88 years (mean, standard deviation: 33.31, 14.07 years). The lesions were predominantly benign (n = 176; 98.3%), with only three (1.7%) being malignant OTs. Conclusion: The distribution of OTs in this study compared well with that in previous reports from Nigeria.


RESUMEN Antecedentes: Los tumores de origen odontogénico (TO) como resultado de los elementos epiteliales y mesenquimales que son parte del aparato de formación de los dientes, se deben considerar como diagnosis diferencial a la hora de analizar lesiones maxilares. Pueden ser quísticos, mixomatosos, o constituidas a veces por una mezcla de áreas quísticas y sólidas. Objetivo: Analizar los TO vistos en el Departamento de Cirugía Maxilofacial del Hospital Docente Ahmadu Bello de Zaria, Nigeria, de 2001 a 2013, a partir de la clasificación de TO de la Organización Mundial de la Salud de 2005. Métodos: Se realizó una búsqueda y análisis retrospectivo de las historias clínicas de todos los pacientes con diagnóstico histopatológico de tumores orofaciales y lesiones tumorales observadas en el Departamento de Cirugía Maxilofacial del Hospital Docente Ahmadu Bello en Zaria, Nigeria, de 2001 a 2013. Resultados: Los tumores odontogénicos constituyeron 179 casos (15.3%) de un total de 1170 tumores orofaciales y lesiones tumorales vistas en el período de estudio. Los 179 TO fueron encontrados en 101 (56.4%) varones y 78 (43.6%) hembras, para un ratio varón-hembra de 1.3:1. Las edades de los pacientes variaron de 12 a 88 años (media, desviación estándar: 33.31, 14.07 años). Las lesiones fueron predominante benignas (n = 176; 98.3%), hallándose solamente tres TO malignos (1.7%). Conclusión: La distribución de TO en este estudio es comparable con la de los reportes anteriores en Nigeria.
