      Abstract

      Plethora of options exists in the diagnosis and management of condylar osteochondroma. The purpose of this study was to provide a congregate information concerning treatment of the osteochondroma involving the mandibular condyle. The search was conducted in Pubmed, Google Scholar, Semantic Scholar and Cochrane database till February2022. 27 studies were included for the final review. The review included a total of 439 patients who underwent surgical management for mandibular condylar osteochondroma. The position of osteochondroma was mentioned in13 studies. Preauricular, retromandibular, endaural, submandibular, transzygomatic and intraoral approaches were used for approaching the tumour. Surgical techniques included resection, conservative condylectomy and total condylectomy. Concomitant orthognathic surgery was performed along with tumour resection in 19 studies. In the entire review, recurrence rate was 0.22% (1/439). Results of the metanalysis showed that two studies reported significant malocclusion events after surgical therapy. Total joint reconstruction after tumour resection has a higher improvement in maximal mouth opening (8mm) compared to vertical ramus osteotomy and no reconstruction groups, which have similar improvements (6mm). The mainstay of treatment of osteochondroma is surgical excision either as condylectomy or conservative condylectomy. Among the various reconstruction modalities, TJR showed better improvement in mouth opening. Adjunct procedures like orthodontic and orthognathic surgery have an important role in holistic management of severe cases. The treating surgeon must choose the surgical procedures in a pragmatic way.
