Jaw bones are exceptional developmentally in having embryonal neuroectodermal cells on one hand and tooth germs on other. They cause destruction of the jaw bones and pose diagnostic challenge.
MATERIAL AND METHODS
Patients attending Oral and Maxillofacial Surgery Department at Osmania General Hospital during the period January 2013-May 2016 presenting with complaints of gradually progressive of jaw swelling, toothache and with radiological evaluation showing osteolytic, sclerotic, and cystic change were subjected to surgical excision. Representative tissue samples were processed routinely and stained by haematoxylin and eosin.
A total of 55 cases of lesions involving jaw bones were studied out of which 21 cases occurred in females and 34 cases in males. 47 lesions were encountered in mandible and 7 lesions in maxilla. A single case of firm-to-hard submandibular swelling was also included in the study. The lesions were categorised into cysts, odontogenic tumours, reactive bone lesions, giant cell lesions, and primary bone tumours. Ameloblastoma was the most common odontogenic tumour type, 15/55; one ameloblastoma case was recurrent followed by radicular cyst 7/55 and dentigerous cyst accounting for six cases and variety of other lesions.
A whole gamut of lesions occurred in the jaws presented with a considerable overlap in clinical, histological, and radiological features. The present study revealed mostly cystic and benign neoplastic lesions.
