[Swallowing after chemotherapy and radiotherapy for laryngeal and hypopharyngeal carcinomas].

UNLABELLED

The main goals of the larynx preservation protocol are eradication of cancer and preservation of a functional larynx with maintenance of respiration, phonation and swallowing. Few studies, however have addressed functional outcomes.

OBJECTIVE

Functional evaluation of oropharyngeal swallowing in patients enrolled in a larynx preservation protocol at the Hospital do Câncer AC Camargo.

METHODS

Evaluation of swallowing was performed by videofluoroscopy in 31 patients, focusing on: oropharyngeal motility disorders, stasis, laryngeal penetration, aspiration and severity of dysphagia.

RESULTS

Swallowing analysis: 5 patients showed inefficient bolus preparation, 14 had changes in the bolus propulsion; 23 patients had a reduced laryngeal elevation, 26 presented with stasis in the vallecula and 14 with stasis in hypopharynx. Nine patients presented silent aspiration. We detected functional swallowing in 11 patients; mild dysphagia in 7; mild/moderate in 7; moderate in 3 and severe dysphagia in 3.

CONCLUSION

Larynx preservation results in changes of swallowing, ranging in their majority from discrete to moderate. Some patients, however, developed severe dysphagia, and oral feeding was not possible.
