[Computerized evaluation of acoustic parameters of voice and speech after partial supracricoid laryngectomy with cricohyoidoepiglottopexy].
Nineteen supracricoid porticol laryngectomy (SCPL) with cricohyoidoepiglottopexy (CHEP) speakers and 19 normal adult laryngeal (NAL) male speakers took part in this prospective study. Computed analysis of the voice and speech parameters was performed using the Computed Speech Lab from Kay Elemectrics. Parameters recorded for voice analysis were the average fundamental frequency, the fundamental frequency standard deviation, the jitter, the shimmer, the noise to harmonic ratio and the degree of voiceless. Parameters recorded for speech analysis were the maximum phonation time of the /a/ vowel, the phrase grouping and number of words read per minute. Speech and voice parameters statistically differed among NAL and SCPL with CHEP speakers. Among SCPL with CHEP speakers, none of the following factors (age, cricopharyngeal myotomy, piriform sinus tension, associated ipsilateral neck dissection, speech rehabilitation therapy) were statistically related to the frequential and durational variables. Jitter of SCPL with CHEP speakers was reduced as time elapsed from CHEP completion increased (p = .002). Maximum phonation time was reduced if one arytenoid cartilage was resected (p = 0.025).
