Soft palate is a part of the palate composed of muscles and mucous membrane. It divides oropharynx from the nasopharynx. Soft palate along with lateral and posterior pharyngeal walls create a three-dimensional muscular valve which is known as velopharyngeal (VP) sphincter. This VP sphincter allows normal breathing and prevents regurgitation of food and fluids in the nasal cavity. It is also required in other functions such as swallowing, blowing, sucking, whistling and sneezing. Any defect in the soft palate, i.e., structurally or neurologically will lead to VP defect due to which normal functions were impaired. Pharyngeal obturator prosthesis restores the congenital and acquired defects of the soft palate and allows adequate closure of palatopharyngeal sphincter. In the present case report, a male patient suffering from pleomorphic adenoma of the soft palate was operated leading to VP insufficiency. This patient was rehabilitated by pharyngeal obturator prosthesis for the improvement of quality of life of the patient.
