[Value of myotomy of the lower constrictor in surgery of tracheo-esophageal puncture]. / Valoración de la miotomía del constrictor inferior en la cirugía de la punción traqueoesofágica.

The importance of the inferior myotomy for speech restoration in total laryngectomized patients following not only primary techniques (speech restoration by tracheo-esophageal puncture during total laryngectomy) but also secondary punctures, is well documented. In this paper, the results obtained by manometric studies applied to 25 patients divided into two groups are shown (the first group) (15 patients) following primary techniques, and the second one (10 patients) following secondary punctures. We observe a sphincter pressure decreasing after secondary myotomy in those patients which previously presented dysphagia, prostheses breaking or intermittent speech, therefore considering the inferior constrictor myotomy as of great value in speech rehabilitation.
