Prótese Total Obturadora em Paciente Irradiado – Relato de Caso

Abstract

Oral sinus communication is one of the most common surgical sequelae for patients with squamous cell carcinoma of the palate. In addition to surgical intervention, chemotherapy and radiotherapy sessions are usually combined for this tumor. Radiotherapy for cancer uses ionizing radiation to destroy tumor cells or prevent their multiplication. Thus, high doses of radiation are used to treat these head and neck tumors, which can cause sequelae such as xerostomia, mucositis, and osteoradionecrosis, with consequent interference in the prognosis for rehabilitation with obturator prostheses. This study reports the oral rehabilitation of a 57-year-old male patient who underwent tumor removal in the hard palate region, followed by 35 radiotherapy sessions with 2 Gy in each session. Due to the sequelae caused in the surgical area, with the presence of oroantral communication, we proposed the creation of a Complete Upper Obturator Prosthesis, restoring the patient's phonetic function, improving his/her chewing capacity, in addition to restoring the aesthetic characteristics, with a comfortable, satisfactory and effectively retentive prosthesis.
