COMPARISON OF THE EFFECT OF TRADITIONAL SEPTOPLASTY AND ENDOSCOPIC SEPTOPLASTY ON VOICE QUALITY

Material-Methods: Based on clinical examination and paranasal CT, these patients were grouped according to the Mladina classification, and 456 patients with Mladine type 3 septal deviation were included in the study. 40 patients who met the study criteria and agreed to undergo surgery were included in the study. The study population comprised 20 patients in the TS group and 20 patients in the ES group. Praat voice analysis program was used for acoustic voice analysis. Preoperative and postoperative (1st and 3rd months) F0, jitter, shimmer and NHR (noise-harmonic ratio) values were compared between the groups.

Results: The F0 and jitter change differed between the groups in the postoperative 1st month according to the preop value (p<0.001), and the F0 and jitter change in the postoperative 3rd month did not differ between the groups according to the preop value (p=0.249, p=0.100) .Preop-post op 1st-month and preop-postop 3rd-month shimmer and NHR change did not differ according to the groups (p=0.905, p=0.066) .There was a statistically significant difference between TS and ES only between pre-op F0-postop 1-month F0 change and preop jitter-post op 1-month jitter changes. In the ES group, F0 and jitter changes were higher at post-op 1 month compared with the TS group.

Conclusion: There is no difference in voice quality between endoscopic and traditional septoplasty methods in long-term evaluations. Keywords : Endoscopic septoplasty, jitter, shimmer, traditional septoplasty, voice analysis
