Abstract/OtherAbstract:
|
After total laryngectomy, the cricopharyngeus muscle, when intact, appears to inhibit the free flow of saliva and secretions past the pharyngeal repair into the upper esophagus. The authors hypothesize that cricopharyngeus myotomy reduces sphincteric pressure, thereby diminishing forces against the pharyngeal suture line. Peak pharyngeal pressures were recorded in patients who underwent total laryngectomy with and without cricopharyngeus myotomy. In patients without concurrent myotomy, peak pharyngeal pressures were all greater than 60 mm Hg. With concurrent myotomy, peak pharyngeal pressures averaged less than 40 mm Hg. Concurrent myotomy carries with it the potential for minimizing postoperative fistulization, eliminating dysphagia of cricopharyngeus spasm, and improving the acquisition of alaryngeal speech. |
