A comparison of surgical and prosthetic treatment for speech disorders attributable to surgically acquired soft palate defects.
Surgical and prosthetic treatments for speech disorders attributable to surgically acquired soft palate defects were investigated. Ten patients who had undergone soft palate resection for extensive cancer served as the subjects. In four patients, the resected portion of the soft palate was confined to the anterior or middle segments, with an intact posterior band, whereas in the remaining six patients the resected portion extended into the posterior edge. An obturator with or without a speech appliance was adapted to all patients in the former group and to one patient in the latter group. The remaining five patients in the latter group underwent surgical reconstruction using a free radial forearm flap immediately after resection of the soft palate. The speech of each patient was evaluated either before and after surgery in those treated only surgically or with and without the obturator in the other patients using a standard intelligibility test of 100 Japanese syllables. These tests showed that two of the four patients with a posterior band of soft palate remaining postsurgically achieved excellent restoration of speech and improvement of velopharyngeal function following placement of a special prosthesis. The patients who had resection extending into the posterior edge of the soft palate obtained better restoration of speech and function from surgical reconstruction rather than prosthetic management. All three patients who had surgical reconstruction, in whom the special obturator was applied achieved a slight increase in speech intelligibility scores resulting from the improvement of velopharyngeal function. These results suggest that surgical reconstruction and prosthetic management may best be applied selectively based on the extent of resection of the soft palate.
