Rehabilitation after laryngectomy with a hypopharyngeal voice prosthesis.

The northwestern laryngeal voice prosthesis contains no vibrator, but produces good voice by means of a properly placed pharyngostomy. The quality of voice production is such that patients have been able to resume former occupations, i.e., teaching and coaching football. The significant difference and advantage of this prosthesis when compared with similar ones to the fistula location. The location in the hypopharynx is in a surgically safe area distant from major vessels. It can be placed at the time of original surgery and is also workable in patients who have had radiation and extensive radical surgery with total reconstruction of their gullet. The prosthesis can be used by primary total laryngectomees while learning esophageal speech or installed in those who are unable to use the electronic larynx or esophageal speech.

Recovery of postoperative swallowing in patients undergoing partial laryngectomy.

This study assessed the achievement of postoperative swallowing in patients undergoing partial laryngectomy surgery. Oropharyngeal swallow efficiency was used to predict time to achievement of outcome. Fifty-five patients were followed for up to 1 year in two hemilaryngectomy and four supraglottic laryngectomy groups. Within 10 days of healing, a videofluoroscopic evaluation enabled the measurement of swallowing efficiency. Times to achievement of oral intake, removal of feeding tube, preoperative diet, and normal swallow were analyzed using actuarial curves. Patients with hemilaryngectomies achieved swallowing rehabilitation sooner than patients with nonextended supraglottic laryngectomies (p < .05) who, in turn, achieved swallowing function sooner than did patients undergoing supraglottic laryngectomies with tongue base resection (p < .05). Median time to attainment of preoperative diet in these three groups was 28 days, 91 days, and > 335 days, respectively. Higher early postoperative oropharyngeal swallow efficiency was related to earlier achievement of oral food intake and of preoperative diet (p < .05). Results show that the time course for swallowing rehabilitation covers an extended postoperative period. In some surgical groups, functional swallowing and eating may be achieved within 3 months of surgery while for other types, significant impairment remains up to 9 months postoperatively Early radiographic assessments of swallowing function are useful in predicting the time to swallow recovery. Recovery of swallowing ability may be delayed in patients who have not achieved oral intake before radiotherapy is started.

Bipedicled lingual flap for lip reconstruction.

Full-thickness loss of the lower lip due to trauma or malignancy presents a difficult reconstructive problem. Numerous reconstructive techniques, including distant flaps, local pedicle flaps, advancements and skin-muscle composite transfers, have been described. The bipedicled lingual flap is a relatively simple procedure that offers many advantages over other techniques since it results in excellent cosmesis without donor site deformity. It causes negligible loss of labial and lingual function. Although it is performed in two stages, its simplicity of execution requires less operative time than many other techniques, and it allows satisfactory reconstruction of unusually large defects.
