Functional effects of intraoral reconstruction with a free radial forearm flap.
Postoperative articulation was investigated in patients who underwent glossectomy and reconstruction with free radial forearm flaps. The methods of evaluation consisted of scores for intelligibility of 100 Japanese syllables and 3 groups of glossal sounds. The glossal sounds, based on palato-lingual contact (lingogram), were useful to evaluate function of the respective parts of the tongue. One patient who had had a partial glossectomy and resection of the floor of the mouth achieved an overall score of 80.5% one year postsurgery, and his glossal sounds were also excellent. Three patients who underwent removal of the floor of the mouth and hemiglossectomy, excluding the root of the tongue, had overall scores ranging from 45.6% to 82.1%. Two of these had particularly low scores for the glossal sounds produced with the rear part of the tongue, and this suggested the necessity for suspension slings to prevent depression of the reconstructed tongue and the floor of the mouth. The hemiglossectomy with partial mandibulectomy had an acceptable score of 68.7%. Chronologically, the glossal sounds produced with the rear part and the blade of the tongue often tended to improve postsurgery.
