Evaluation of failed sphincter pharyngoplasties.
A review of 30 failed sphincter pharyngoplasties is presented. Failure may be caused by inappropriate surgical planning, inadequate surgical technique, or inappropriate patient selection. Problems with surgical planning and technique that lead to failure were low flap placement, flap dehiscence, and flaps not approximated in midline. Problems with patient selection that lead to failure were large velopharyngeal gap on videofluoroscopy, and residual speech (articulation) deficits. Careful pre- and postoperative evaluation has led to refinement of the surgical procedure and improved outcome. Success rate improved from 67.65% in the first 5 years to 86% in the last 5 years of this 15-year series.
