Osteochondroma of the mandibular condyle: A case report

Abstract

Introduction: Osteochondromas or osteocartilaginous exostoses are the most common benign tumors of the bones. It is characterized as a type of overgrowth that can occur in any bone where cartilage forms bone. It is uncommon in this part of body because of intramembranous origin of craniofacial bones. Osteochondromas do not result from any injury and the exact cause remains unknown. recent research has indicated that multiple osteochondromas is an autosomal dominant inherited disease. the treatment choice for osteochondroma is surgical removal of solitary lesion or partial excision of the outgrowth when symptoms cause motion limitations or nerve and blood vessel impingements. Osteochondroma of the mandibular condyle is extremely rare. case report: A 45-year-old female presented to our department with diffuse swelling in her left side of face and pain in her left ear while opening the mouth since last six months. clinically, mouth opening was limited with deviation of mandible towards right side while opening mouth. there was unilateral posterior crossbite on the right side. Protrusive movement and lateral excursions of mandible were restricted. the lesion appeared to be benign bony lesion and complete surgical excision of the whole tumor mass along with condylectomy was performed under general anesthesia. conclusion: As osteochondroma is a benign neoplasm, various treatment modalities include resection of tumor along with condylectomy, condylectomy with reconstruction of the resected condyle if indicated or selected tumor removal without condylectomy. the prognosis of osteochondroma is usually excellent after adequate excision. this case showed no recurrence after the treatment. Malignant transformation of the lesion is exceedingly rare.
