Speech Analysis Of Pre-and Post-Uvulopalatopharyngoplasty Combined With Low-Temperature Plasma Radiofrequeney Ablation To Inferior Turbinate In Patients With Severe OSAHS

Objectives:To analyze the pre-and post-voice of severe OSAHS patients received UPPP combined with low-temperature plasma radiofrequency ablation to inferior turbinate.To study the influence of operation on nasalance rate and resonance function.Methods:The study included32severe OSAHS patients who received UPPP combined with low-temperature plasma radiofrequency ablation to inferior turbinate.Using multi-channel voice analysis system to test the cavity resonance characteristics and energy distribution of patients (including pre-and post-operative) when they speak/a:/.The frequency spectrum was4000Hz (FR1,FR2,FR.3,FR4).Using nasal flow meter to test the nasalance rate when severe OSAHS patients speak non nasal sentence,orinasal sentence and nasal sentence.Results:FR2energy values of the head cavity and mouth cavity of severe OSAHS patients heighten significantly after operation(P<0.05);FR1energy values of head,mouth and thoracic cavity were higher than that of in normal males after operation(P<0.05). FR2,FR3,FR4energy values of head cavity,FR2,FR3energy values of mouth cavity,FR2energy values of thoracic cavity were lower than those of in normal males’ after operation(P<0.05).Postoperative FR1～FR4energy value of laryngeal cavity had no significant difference.The nasalance rate of orinasal sentence and nasal sentence heighten significantly after operation(P<0.05).The nasalance rate of non nasal sentence had no obvious change(P<0.05).The nasalance rate of non nasal sentence,orinasal sentence and nasal sentence were within the normal reference value range.Conclusions:1.UPPP combined with low-temperature plasma radiofrequency ablation to inferior turbinate lifted the blocking of oropharyngeal cavity and nasal of severe OSAHS patients. Air can enter smoothly into the nasopharyngeal cavity,nasal cavity through the soft palate,then changes the resonance characteristics of the head cavity and oral.Because of UPPP does not change the physiological structure of throat and chest,so the changes of pre-and post-operative resonance characteristics was not obvious.We believe that the multi channel speech analysis system not only can help the singer to determine its vocal type in the field of vocal music teaching,also can help clinicians to assessment voice and surgery effect of nasal and throat disease.2.UPPP combined with low-temperature plasma radiofrequency ablation to inferior turbinate not only affect the resonance characteristics of head cavity and oral,also affect the soft palate closure function.We should be careful with professional singing,drama,radio host when they received UPPP combined with low-temperature plasma radiofrequency ablation to inferior turbinate.We have to tell them that their speech may be changed after surgery.
