Abstract
Background and Objectives : Aerodynamic analysis is an examination which provides information regarding various vocalization measures indicating laryngeal efficiency. Voice evaluation using such examination must be capable of distinguishing between normal to abnormal voice. It also observes variables on aerodynamic characteristics by gender in regards to patients of vocal disorders, especially of vocal cord paralysis and vocal polyp, and compares the conditions before and after surgery. This paper therefore, seeks to build a framework for establishing standard levels of aerodynamical characteristic on vocal disorders. Subjects and Methods : The study was intended for a total number of 20 patients with vocal polyp or unilateral vocal cord paralysis. Those with the vocal polyp underwent laryngomycroscopy surgery and the vocal cord paralysis, vocal fold injection using Restylane. Aerodynamic analysis fulfilled the Maximum sustained Phonation (MXPH) and Voicing Efficiency (VOEF) by using PAS Model 6600 (KayPENTAX, USA). Results : In MXPH, increase in PHOT were evident with vocal polyp after surgery. As for patients with vocal cord paralysis, MAXDB, MEADB, DHODB, PHOT all have increased and MEAP, PEF, MEAF decreased after surgery. In VOEF, patients with vocal cord paralysis who underwent surgery showed increase in MAXDB, MEADB, DHODB, FET100, ARES, but decreases in PEF, TARF. Conclusion : Overall, it can be concluded that patients with the vocal polyp and vocal cord paralysis seemed to get closer to the normal values after than before surgery in majority of measures. This confirms that the function of their vocal cord has improved nearly to normality through operations.
