Abstract：Osteochondroma is typically located at the metaphyseal region of long bones.Its occurrence in the jawbone,particularly in the coronoid process,is exceedingly rare.This article reports a case of osteochondroma of the right mandibular coronoid process in a 63-year-old female.The patient presented with"a painless mass on the right cheek for more than 5 months and a new mass for 1 month".CT revealed a mass in the right coronoid process area.A modified preauricular-zygomatic arch approach was used for expanded resection of the tumor and partial coronoid process resection.During the procedure,the facial nerve branches were fully protected,and zygomatic arch osteotomy,reduction,and titanium plate fixation were performed.Postoperative pathology confirmed osteochondroma.The patient's facial appearance and mouth opening improved,and the prognosis was good.This article focuses on the selection of surgical approaches for lesions located deep to the coracoid process,highlighting the advantages of the modified preauricular-zygomatic arch approach in achieving adequate surgical exposure,ensuring facial nerve preservation,and facilitating osteotomy and reduction.This case serves as a valuable reference for the diagnosis and management of coracoid osteochondroma and the refinement of surgical strategies.
