Background: The aim of this study was to evaluate changes in acoustic features of voice after septoplasty and to establish concepts of patient management awl a rational therapeutic approach.
Material/Methods: Before and one month after surgery, phonetically balanced sentences and sustained vowels a, e, and were recorded and digitalized with MDVP (Multi Dimensional Voice Program, Kay Elemetrics) in all patients for an evaluation of nasal resonance, voice handicap index (VHI), and active active anterior. These parameters were estimated: average fundamental frequency (Fo), jitter percent, shimmer, noise-to-harmonics ratio (NHR), voice turbulence index (VTI), soft, phonation index (Sill), degree of voicelessness (DUV), degree of voice breaks (DVB), and peak amplitude variation (vAm).
Results: One month after surgery the data showed an improvement in all the acoustic parameters and a normalization of nasalance.
Conclusions: The results highlight the impact of septoplasty on nasalance and voice. In selected cases, such as severe nasal septum deviation, the decision to perform septoplasty depends on its potential effect off speech and respiratory function. An objective evaluation of voice and nasalance helps the specialist hi the management of these patients.
