Conditioning prostheses viewed from the standpoint of speech adaptation.

Subjects who had adapted to experimental alveolar-palatal prostheses for 2 weeks were able to speak naturally with them after a lapse of a month. Physiologic data on jaw motions and tongue-palate contacts during speech showed a rapid return to compensatory articulatory patterns. A single subject who had previously adapted to an experimental prosthesis over a period of a week made the same type of compensatory jaw adjustments when speaking with the prosthesis again 1 year later.

Modification of compensatory swallowing in a supraglottic laryngectomy patient.

Results are presented for repeated videofluoroscopic and scintigraphic examinations of a supraglottic laryngectomy patient, illustrating the successful use and later changes in a compensatory swallow. Issues in patient management are outlined, stressing the importance of interaction between radiologists and dysphagia therapists in the rehabilitation of such patients.

Swallowing recovery following anterior tongue and floor of mouth surgery.

Videofluoroscopic and clinical data are presented for postsurgical recovery of tongue and hyoid activity during swallowing. Comparison is made to normal controls. Postsurgery, but prior to radiotherapy, both the lingual propulsive gesture and hyoid velocity were slower than normal. These features of the swallow had returned to the normal range following radiotherapy. The general sequencing of swallowing events, and the relationship of the end of the tongue propulsion to anterior hyoid motion were normal in those patients able to swallow. In this patient group, postsurgical radiotherapy did not prevent continued recovery of swallowing function sufficient for oral nutrition.

Scintigraphic assessment of aspiration in head and neck cancer patients with tracheostomy.

Tracheopulmonary aspiration commonly occurs in patients with dysphagia related to head and neck cancer. Scintigraphic studies were performed in 280 patients with head and neck cancer; 33% of these patients had tracheopulmonary aspiration. A subgroup of 18 tracheostomized patients had a tracheostomy tube with a removable obturator, so they could be studied with the tracheostomy open or occluded. When the tracheostomy was occluded the patients aspirated less frequently, and in significantly smaller quantities, than when it was open. When feasible, occluding the tracheostomy tube or permanent surgical closure may reduce or eliminate tracheopulmonary aspiration in these patients.
