Abstract

BackgroundAn osteoma is a benign tumor of bone with unknown etiology and is considered rare, mostly restricted to the craniofacial skeleton.Case presentationThis case report describes an uncommon condylar osteoma in a 67 years old white female patient with laterognathism to the left side, limited mouth opening, aesthetic change and pain associated with the right temporomandibular joint (TMJ). The histopathological examination confirmed osteoma. The lesion was surgically excised and immediate reconstruction was carried out using a custom-made total TMJ prosthesis. The patient has been in follow-up for 2 years, with no symptoms.ConclusionsUnilateral total TMJ prosthesis can be considered to replacement of TMJ after osteoma excision with resection of the condyle.

Highlights

An osteoma is a benign tumor of bone with unknown etiology and is considered rare, mostly restricted to the craniofacial skeleton.Case presentation: This case report describes an uncommon condylar osteoma in a 67 years old white female patient with laterognathism to the left side, limited mouth opening, aesthetic change and pain associated with the right temporomandibular joint (TMJ)
This study reports a case of an uncommon condylar osteoma that was identified due to an aesthetic change of the TMJ and immediate reconstruction using a total TMJ prosthesis
Due to the size of the lesion, the decision was to excise the tumor with resection of the condyle and to construct a custom-made total temporomandibular joint prosthesis for reconstruction

Summary

Introduction

An osteoma is a benign tumor of bone with unknown etiology and is considered rare, mostly restricted to the craniofacial skeleton.Case presentation: This case report describes an uncommon condylar osteoma in a 67 years old white female patient with laterognathism to the left side, limited mouth opening, aesthetic change and pain associated with the right temporomandibular joint (TMJ). Conclusions: Unilateral total TMJ prosthesis can be considered to replacement of TMJ after osteoma excision with resection of the condyle. Osteomas in the mandible have been reported as a cause of trismus, limitation of mouth opening,
