title: [Effect of the extents of surgical resection in total laryngectomy on esophageal voice and speech rehabilitation].
abstract: The study of functional results of total laryngectomy cannot be separated from articulation of esophageal voice and speech. To achieve success of phoniatric rehabilitation in laringectomized patients, it is necessary to be well aware of pathological sequelae of the very operation, long-term adverse effect of oncological risk factors as well as postoperative anatomo-physiological changes. Anatomic results of total laryngectomy depend on the type of surgical intervention and probable radiotherapy. The extent of surgical procedure, primary dictated by oncological indications, has the essential effect to articulation of esophageal voice and speech. If possible for oncological reasons, hyoid bone should be particularly left intact. Extensive surgical interventions of hypopharynx and the base of the tongue during laryngectomy, neck dissection--especially the radical one, and subsequent radiotherapy, all of them significantly reduce the possibility to produce esophageal voice and speech. Total laryngectomy eliminates the creator of voice and vibrations, which are acoustically perceived as esophageal voice, proceeding at the level of pharyngoesophageal junction. For this reason, the quality of newly created vibrating narrowing is especially important.
