“…Consequently, this in turn will result in changes in the vocal tract like increased nasal volume, decreased acoustic damping and increased nasal patency, thereby providing better acoustic space for good resonance [4,20]. The findings of the present study are in consonance with literature [7,10]. However, the findings are contrasting with the results obtained by researchers who did not obtain acoustical changes post-septoplasty [4,21].…”

“…The authors reported significant improvement in fundamental frequency, amplitude perturbation and frequency perturbation measures after 1 month of recovery from septoplasty [7]. Similarly, Konior and colleagues reported that post-septoplasty there was increased nasal airflow and enhanced perceptual quality of the voice for/n/phoneme [10]. These evidences collectively support there are changes in resonance after surgical management.…”

Resonance change is a common clinical symptom in individuals with deviated nasal septum. Often this anatomical deficit is surgically treated by septoplasty. Therefore monitoring resonance changes using acoustical tools is vital. Hence, the study investigated cepstral measure differences in subjects with deviated nasal septum compared to normals. A case-control study design involving 20 subjects within 18-40 years divided into Group I of 10 subjects with deviated nasal septum (DNS) and Group II of 10 normal subjects participated. All the subjects sustained nasalized vowel /ã/ at 10 cm mouth-microphone distance for minimum of 5 seconds. For Group I, voice sample was recorded in 2 conditions, 2 days pre-septoplasty and 1 month post-septoplasty. Cepstral peak prominence (CPP) and smooth cepstral peak prominence (CPPS) values was extracted using the Hillenbrand algorithm. Mean values revealed increased CPP and CPPS measure post-septoplasty when compared to pre-septoplasty. ANOVA showed statistically significant difference only for CPPS at p = 0.00. The higher cepstral values of post-septoplasty is due to widened nasal passage that leads to increased nasal volume, decreased acoustic damping and increased nasal patency. These changes in supraglottic chambers will result in a better acoustic space for good resonance. However, the CPPS values were not similar to normal subjects because of scarring or incomplete recovery of the outer mucosal layer of the nasal tract. Thus, we can conclude that cepstral analysis is a sensitive tool to detect resonance changes in the nasal patency.

“…The degree of septal deviation from the centre determines the severity of the disorder. 6 Septal deviations affect the free aeration and cause nasal obstruction, blockage, allergic rhinitis and dryness of throat and hence influence the person's quality of life. DNS can lead to sinusitis, affect the sinus drainage and also influence the resonance and voice characteristics of speech.…”

Background: Septoplasty is one the most commonly performed surgery in ENT. The aim of this study was to evaluate change in voice after septoplasty using voice handicap index (VHI).Methods: The current study was conducted at Department of ENT, SMGS Hospital, Government Medical College, Jammu, from October 2017 to November 2018. The study population was the patients who had come to the department with deviated nasal septum admitted for septoplasty. Voice assessment was done by Subjective Voice evaluation using VHI. It was done at three times i.e. preoperatively, postoperatively at 1 week and then postoperatively at 1 month. Results: Out of 50 cases operated, 84% patients of present study were in the age group of 18-30 years. The mean age was 25 years. The eldest patient in our study was 55 years old. 40 patients were males and 10 were females with male: female ratio of 4:1. Mean VHI score at preoperative, postoperative 1 week and postoperative 1 month were 23.2, 22 and 21.5 respectively. No statistical difference was obtained while comparing the mean VHI score at different time intervals. The scores between 0-30 are in the mild category i.e. minimal amount of handicap.Conclusions: According to our experience a widened nasal cavity has no effect on voice quality and procedures about nasal obstruction like septoplasty can be performed safely. However, professional voice users, in particular, should be informed about the possible minor postoperative changes, before the septoplasty procedure.

Deviated nasal septum (DNS) is a common disorder which alters the nasal cavity anatomically and physiologically and results in nasal obstruction for breathing, nasal blockage, allergies, allergic rhinitis, and dryness of throat, thus influencing the person's quality of life. Literature indicates that acoustic and resonatory characteristics of voice are negatively influenced in individuals with DNS due to the compensation by laryngeal system to the blockage in the resonatory chamber. In this context, the present study was aimed to investigate the voice related quality of life in individuals with deviated nasal septum. Forty individuals with severely deviated nasal septum confirmed by an Otorhinolaryngologist through anterior rhinoscopy, computerized tomography and twenty five age and gender matched controls filled the Kannada version of Voice Handicap Index-10 (VHI) questionnaire. Results indicated significant impact of deviated nasal septum on voice related quality of life in 55% of the participants with DNS. Results of Mann-Whitney U test indicated significant effect of DNS on VHI scores in individuals with DNS compared to controls (p<0.001). With respect to response to the individual questions under VHI, although response was negative to most of the questions, two questions that received highest score belong to physical domain of VHI and are related to breathing difficulty and variations in voice throughout the day, indicating that they have more difficulty due to nasal blockage to airflow per se than their day-to-day functionality or communication.
