Restoration of Facial Deformity Caused by a Radicular Cyst after Marsupialization

Abstract

Radicular cyst is the most common type of odontogenic cyst. The cyst originates from the maxilla occasionally, causes facial deformation and displacement of adjacent structures. An 11-year-old girl visited the outpatient clinic with the left cheek swelling and facial asymmetry. The cheek lesion was hard, accompanied by tenderness. The computed tomography (CT) scans revealed a large unilocular radicular cyst, which involved the floor of the left maxillary sinus, the palatine and al veolar process of the left maxilla. It was treated by transnasal marsupialization under endoscopic guidance. At the one postoperative year follow-up, facial asymmetry was restored and the marsupialization site was closed. The follow-up CT scan showed that the site of a radicular cyst was restored by bone formation. Therefore, we report a case of radicular cyst accompanied with facial asymmetry, which was restored after marsupialization. We also discuss the mechanism about the restoration of facial asymmetry.� Korean J Otorhinolaryngol-Head Neck Surg 2013;56:599-602 Key WordsZZEndoscopic surgery ㆍFacial asymmetry ㆍMaxilla ㆍOdontogenic cyst ㆍ Radicular cyst ㆍRestoration.
