Özet
Objective: Endotracheal intubation (ETI) and laryngeal mask airways (LMA) can cause various laryngeal symptoms and changes in the acoustical characteristics of the voice in the postoperative period. In this study, we aimed to compare the effects of ETI, classical LMA, proseal LMA and I gel LMA on laryngeal symptoms and acoustic analysis parameters of the voice. Material and Methods: Eighty patients who underwent lower abdomen and extremity surgery, which do not effect the formation of the voice, were included in the study. A clinical survey sheet that included questions about hoarseness, globus pharyngeus, need for clearing throat, sore throat, loss of voice, unpleasant voice and cracking voice, was filled by the patients preoperatively, and on postoperative 2nd and 24th hours. All patients had acoustic analyses in an isolated room in the Otorhinolaryngology polyclinic. Acoustic analysis included parameters of basic frequency, jitter (measures of the cycle-to-cycle variations of fundamental frequency), shimmer (measures of the cycle-to-cycle variations of fundamental amplitude), harmonic/noise ratio and normalized noise energy. Results: The increase was statistically significant in group ETI preoperatively and on postoperative 2nd hour when compared to the other groups (p=0.005). In ETI group, hoarseness and need to clearing throat were significantly higher. In classical LMA group, need to clearing throat was significantly higher. No differences were found between T2 and T24 time periods for loss of voice parameters (p=0.179, p=1.000). These clinical evaluations were present in the early postoperative period, and they decreased to normal values on the postoperative 24th hour. In acoustic analysis, only the jitter parameter in the proseal LMA group changed significantly on the 2nd postoperative hour. Other acoustic parameters did not change significantly. Conclusion: We suppose that ETI and classical LMA may have effects on voice functions in the early postoperative period, and newly developed LMAs, especially gel structured laryngeal mask airways, which are not dilated with air, have minimal effects on voice functions and laryngeal complaints. © 2014 by Türkiye Klinikleri.
