ABSTRACT

Objective:

To investigate the effects of septoplasty on the acoustic parameters of voice.

Methods:

In total, 23 patients (seven females and 16 males; average age, 32.13±9.67 years; age range: 19-56 years) with a diagnosis of nasal septal deviation and who underwent septoplasty were included. Preoperative and on postoperative 30th day, acoustic analysis of voice was conducted for all patients. The recordings of /mana/ vowel were used to evaluate average fundamental frequency (F0), jitter, shimmer, and noise-to-harmony ratio (NHR). F0, shimmer percent, jitter percent, and NHR of two terms were compared. A p-value<0.05 was considered to indicate statistical significance.

Results:

A statistically significant change was not observed in F0 (p=0.741), jitter (p=0.930), and shimmer (p=0.128) measured preoperatively and on postoperative day 30. However, the increase in NHR measured on postoperative day 30 were statistically significant compared with preoperative NHR (p=0.017).

Conclusion:

According to the findings of this study, except NHR value, no statistically significant changes on F0, jitter and shimmer were detected after septoplasty.

ÖZET

Amaç:

Septoplastinin, sesin akustik parametreleri üzerine etkilerini incelemektir.

Yöntemler:

Nazal septum deviyasyonu nedeniyle septoplasti operasyonu olan 23 olgu (yedi kadın, 16 erkek; ortalama yaş 32.13±9.67 yıl, yaş aralığı: 19-56 yıl) çalışmaya dahil edildi. Preoperatif ve postoperatif 30. günlerde tüm hastalara akustik ses analizi uygulandı. Ortalama fundamental frekans (F0), jitter, shimmer ve harmonik gürültü oranı (HNR) parametrelerini karşılaştırmak için /mana/ kelimesi kaydı kullanıldı. İstatistiksel anlamlılık p<0.05 düzeyinde değerlendirildi.

Bulgular:

Preoperatif döneme göre postoperatif 30. günde F0 (p=0.741), jitter (p=0.930), shimmer ölçümlerindeki değişim istatistiksel olarak anlamlı bulunmadı (p=0.128). Bununla birlikte, preoperatif döneme göre postoperatif 30. günde HNR ölçümlerindeki artış istatistiksel olarak anlamlı idi (p=0.017).

Sonuç:

Bu çalışmanın bulgularına göre, septoplasti sonrası HNR değeri dışında F0, jitter ve shimmer için istatistiksel açıdan anlamlı değişiklik saptanmadı.
