Rehabilitation of a Partial-Maxillectomy Patient with a Split Obturator in Restricted Mouth Opening

A Case Report

Abstract

Rehabilitation following surgical resection of the maxillary region is a challenging task for maxillofacial prosthodontists, with defect size and location impacting the level of impairment. The communication between the nasal and oral cavities often cause difficulties with speech, swallowing and aesthetic appearance. An obturator prosthesis is commonly used to address these issues in hemi maxillectomy cases. This article presents a case of maxillary defect caused by squamous cell carcinoma, featuring unfavourable undercuts and the patient with limited mouth opening. The defect was successfully treated with an immediate obturator post-surgery, followed by a one-piece, closed hollow bulb obturator. By utilizing the remaining palate and dentition, the prosthesis maximized support, stability and retention, while acting as a barrier between the oral and nasal cavities.
