The restoration of velopharyngeal function after extensive soft palate resection to treat malignant oropharyngeal tumors is a major challenge to reconstructive surgeons. The authors had previously reconstructed soft palatal defects routinely with the folded forearm flap. A patient who had more than half of the soft palate excised experienced postoperative velopharyngeal dysfunction. To restore efficient velopharyngeal function, pharyngoplasty was additively applied where the folded ridge of the forearm flap was sutured to the posterior pharyngeal wall in an inverse manner of the pharyngeal flap technique. The essence of the procedure was positive narrowing of the nasopharyngeal space. Five patients who underwent this pharyngoplasty and another five who did not were evaluated for postoperative functions of speech intelligibility and of nasal regurgitation during oral feeding. The velopharyngeal movements of all patients were examined under a nasopharyngeal endoscope. The evaluations demonstrated that this surgical procedure afforded satisfactory results. This positive narrowing pharyngoplasty technique is simple, easy, and minimally invasive to the remaining healthy tissue, and it is the method of choice for the reconstruction of the soft palate after malignant tumor resection.
