Objectives: Mechanical fixation of the vocal folds, most frequently develops after long-term intubation. The endoscopic arytenoid lateropexy combined with endolaryngeal mobilization technique, could result good functional (vital capacity) result without tracheotomy. Very few data are available in the literature about the postoperative phoniatric results of interventions performed due to posterior commissure scary fixations.
Study design: Objective phoniatric results (Jitter, Shimmer, MPT, Pitch, Noise to harmonic ratio) were measured in sustained “a” in 5 consecutive patients operated with endoscopic arytenoid lateropexy combined with endolaryngeal mobilization with CO2 laser and a right-angled endolaryngeal scythe cut through the crycoarytenoid joint.
Results: The average late post operative results were MPT 6.3 sec Jitter 0.54% Shimmer 4.98% Noise to harmonic ratio 17.46 dB Pitch 170 Hz . The voice quality in many cases reached the normal range, according to the subjective measurements of GRBAS scale.
Conclusion: After proper mobilization, with endoscopic arytenoid lateropexy stable improvements can be achieved in breathing ability without the need for tracheostomy and the voice quality will be relatively good the ibhjective voice parameters nearly reached the normal range even in severe ankylotic stenoses.
