NOT ALL JAW LESIONS WITH IMPACTED TOOTH ARE DENTIGEROUS CYST- A CASE REPORT OF BENIGN ODONTOGENIC TUMOUR

Abstract

Jaw lesions with impacted tooth lets us suppose dentigerous cyst as most common diagnosis. However there is much more to this clinical entity and nearly ten other histological and radiological diagnosis could be made of such lesion. There is paucity of literature on these alternative diagnosis . We present here a case of benign odontogenic tumour of maxilla in a female in her early twenties which we initially thought was a dentigerous cyst. Dentigerous cyst is type of developmental odontogenic cyst seen most commonly associated with mandible molars(80%) followed by maxillary canine(20%). It is second most common odontogenic cyst after periradicular cyst which is inammatory infectious cyst. We present a case report of a very large benign odontogenic tumour associated with left maxillary canine causing large maxillary swelling and ballooning of anterolateral wall of maxillary sinus and oroantral stula. These tumour have a very indolent course and subtle symptoms but when neglected causes maxillofacial deformity and asymmetry of face. A 21 year female presented with maxillary swelling on left side of midface causing facial deformity and asymmetry. The swelling was of the size of a cricket ball extending from inferior orbital margin to upper alveolus of left side inferiorly and from lateral wall of nose medially to anterolateral wall of maxilla laterally. The swelling caused loosening of two teeth and broadening of upper jaw on left side and rounding of inferior orbital margin due to pressure expansion and thinning of bony cortex all around. A CECT of PNS along with USG and FNAC was done for maxillary swelling which conrmed our diagnosis. Enucleation of cyst with curettage was done via Caldwell Luc approach.
