Functional laryngeal surgery - critical determinants of successful rehabilitation.

This study addresses the functional outcome and rehabilitative process in 30 partial laryngectomies carried out for laryngeal (22) und hypoorpharyngeal (8) cancers at the department of H/N Surgery, The kidwai Memorial Institute of Oncology. Bangalore, India from 1985-1995, Special emphasis is directed towards post-surgical convalescence after various partial laryngeetomy techniques which include 6 vertical laryngectomies (V L / VPL). 17 supraglottic laryngectomies (SG L), and 7 supracricoid laryngectomies with Cricohyoidepexy (CHP). Rehabilitative success was measured with respect to the ease of dccannulation, resumption of normal deglutition and speech analysis - both objectively using standard speech analytical equipment in a speech laboratory and subjectively using the services of blinded judges to score recorded speech of patients. The speech analysis indicate that past SGL speech was the superior most followed by V L and C H P in that order. Aspiration was deemed as minimal and inconsequential after V L/VPL followed by CHP;and SGL, in the order of severity;the extended modifications to resect the arytenoid and / or basE of tongue and / or piriform fossa faring worse than classic standard technique.
