Extensive Partial Obturador Oropharyngeal in Class IV Aramany after Oral Adenocarcinoma

Abstract

When a patient is interrupted by velopharyngeal closure or defects in the hard palate, air escapes inappropriately through the nose in nasal speech sounds. The obturator prosthesis with extension to the oropharynx is currently the best indication for maxillary defects, but it also represents a challenge for manufacturing and oral adaptation. The aim of this study was to report a clinical case of successful prosthetic rehabilitation of a 65-year-old woman who presented with a defect in the maxilla, soft palate, tonsil, and oropharynx after treatment for polymorphous low-grade adenocarcinoma. With her considerable loss of structure and tissue, she reported difficulties with impaired functions such as chewing, swallowing, and speaking and difficulty interacting with people. The oral rehabilitation was performed with an oropharyngeal obturator prosthesis with an extension to the oropharynx and a total mandibular denture. This case demonstrates that the rehabilitation with an oropharyngeal obturator prosthesis with an extension to the oropharynx and a total mandibular denture provides speech, chewing, and phonetics, directly interfering with her social life in the mutilated patient.
