Abstract:
BACKGROUND AND OBJECTIVES: Septoplasty with turbinoplasty has the potential to affect voice because it alters the vocal tract. We conducted a study to evaluate the postoperative voice changes and aid using subjective and objective data regarding the effect of surgery. SUBJECTS AND METHOD: To rule out gender bias, only 23 male patients were enrolled. Voice change was analyzed by a subjective test through a questionnaire and an objective test through acoustic analysis. During each recording session, the subject uttered the words [^m ma: the Korean word for "mother"] and [Nu Na: the Korean word for "sister"]. We then analyzed the nasal consonant ([m] in [^m ma]), the nasalized vowel ([a] in [^m ma] and [a] in [Nu Na]), and the intensity of nasal sound. RESULTS: In the subjective study, 73.9% of patients reported an improvement in the quality of voice after surgery. Most of the patients reported a reduction in twang. In the objective study, there was a tendency for increased formant frequencies in the nasal consonant, and F1 of [m] in [^m ma] was increased significantly (p=0.003). There was also a tendency for decreased formant frequencies in the nasalized vowel, F2 of [a] in [^m ma] and F1 of [a] in [Nu Na] were decreased significantly (p<0.001), and there was an increase in the intensity of nasal sound, [^m ma] (p=0.009) and [Nu Na] (p=0.013). CONCLUSION: Nasal sound became clearer with reduced twang after surgery. It is important to keep the phonetic aspect in mind when patients are undergoing septoplasty with turbinoplasty.
