The potential effects of rhinoplasty on voice

Potential Effects of Rhinoplasty on Voice in Professional Voice Users

BACKGROUND AND AIM

Surgical procedures involving the manipulation of the airway structure have the potential to affect the quality of voice by changing the resonance properties. Regarding this, the present study was conducted to investigate the effect of rhinoplasty on the voice of professional voice users.

METHODS AND MATERIALS

This cohort study was conducted on 30 professional voice users. For the purpose of the study, the patients completed the Voice Handicap Index (VHI). In addition, they were subjected to voice analysis that included the measurement of nasality in speech production (i.e., nasalance), using the nasometer II. Computerized speech lab was also utilized to examine vowels /e/ and /a/, each of which was sustained for 5 sec by the participants.

RESULTS

The mean VHI scores were 8.5 ± 1.98 and 7.36 ± 1.71 before and after the surgery, respectively, indicating no significant difference between the two investigated stages (Z = - 0.53, P = 0.59). However, there was a significant difference between the patients with and without preoperative obstruction in terms of the VHI score (χ²= 11.06, P = 0.004). With regard to orality, it had the mean values of 16.86 ± 7.45 and 15.22 ± 7.37 before and after the surgery, respectively. Furthermore, the mean values of nasality at the pre- and post-operation stages were 59.42 ± 6.04 and 56.28 ± 10.07, respectively. The comparison between the pre- and post-surgical orality and nasality revealed no significant difference (t = 1.226, P = 0.23 and t = 0.93, P = 0.36, respectively).

CONCLUSION

Although rhinoplasty is supposed to affect voice and vocal resonation, the induced changes are not problematic for the professional voice users.

Evaluation of Aesthetic and Functional Outcomes After Open Rhinoplasty: A Quasi-experimental Study by the Aid of ROE and RHINO Questionnaires

BACKGROUND AND AIMS

Rhinoplasty is one of the common plastic surgery procedures which has a high rate in Iran. There are several tools for assessing the outcomes and quality of life after this surgical procedure which rhinoplasty outcome evaluation (ROE) questionnaire and rhinoplasty health inventory and nasal outcomes are two of them. The aim of this study was to investigate the aesthetic and functional outcomes of rhinoplasty by the aid of ROE and RHINO scales in patients who presented to a referral center in Iran.

MATERIALS AND METHODS

This prospective, quasi-experimental study was performed on patients who referred to the plastic surgery clinic of Imam Khomeini hospital complex during 2017 to 2019 and underwent open rhinoplasty. ROE and RHINO questionnaires were filled by patients before and 6 months after the surgery. Surgical outcomes and aesthetic satisfaction rate were evaluated in different age groups, genders and educational levels. The data were analyzed by version 21 of SPSS software.

RESULTS

ROE score increased from 51.27 ± 10.54 to 79.6 ± 9.67 (P < 0.001). In addition, RHINO score increased from 64.13 ± 11.43 to 83.36 ± 11.03 (P < 0.001). The most common satisfaction factors among patients in this study were "nose feels more natural" in 62% of patients and "tip rotation is good" in 32% of patients. Furthermore, the most common causes of dissatisfaction in patients were "nose too wide" in 25% of patients and "tip bulbous" in 25% of patients.

CONCLUSION

ROE and RHINO scales are effective for assessing rhinoplasty outcomes. The satisfaction rate of rhinoplasty is high in Iran and is related to the natural shape of the nose in addition to the tip rotation.

Future Direction in Rhinoplasty: Functional Improvements for a Better Outcome

The nose plays both an aesthetic and functional role in the human body. Physiologically, the nose is an important part of the upper airway. Aesthetically, it is the central focal point of the face. Thus, rhinoplasty has evolved to be both an aesthetic and functional surgery, as the manipulation of the aesthetic subunits of the nose inadvertently leads to the functional alterations of the nose. While the aesthetic goals of rhinoplasty are well described in the literature, functional outcomes from rhinoplasty have been more challenging to delineate. Rhinoplasty can have an impact on the sense of smell, sleep apnea, oxygenation, cognitive function, cardiovascular function, and voice. We have systematically reviewed the current literature in regard to functional rhinoplasty and septoplasty to summarize current surgical maneuvers and their impact on nasal function, along with physiological and perceived functional changes from rhinoplasty.

Effects and Changes on Voice After Rhinoplasty: A Long-Term Report

Introduction

Vocal changes after rhinoplasty have been poorly investigated, although this surgical procedure is nowadays one of the most requested. The production of voice largely depends on the anatomy and the size of the pyramid and the nasal cavity. The authors report 51 cases of both closed and open rhinoplasty and propose a 2-year report to analyze potential effective changes on voice.

Materials and Methods

Fifty-one patients were enrolled and evaluated from September of 2012 to January of 2018. All patients were studied before and 2 years after surgery. Vocal changes were assessed with an objective and a subjective evaluation. The first one allowed to perform the measurement of the intensity and frequency of vowel sound ("a") and nasal consonant sounds ("n" and "m"). For the subjective evaluation, our modified version of Voice Handicap Index Score allowed us to evaluate every single characteristic of the personal perception of voice.

Results

The objective evaluation showed an increased frequency of production of the consonant sounds in 62% of cases and an increased frequency of production of the vowel sound in 68% of cases. The subjective evaluation allowed us to notice significant changes after surgery (P = .044). No significant differences were noticed between closed and open approach.

Conclusion

Reduction rhinoplasty technique proved to induce several alterations on vocal pattern. The surgeon should always inform patients about the potential effects on the voice, particularly when such changes may produce influences on the working life.

Does Open Rhinoplasty Alter Voice Quality?

PURPOSE

The voice can change after upper airway manipulation. The present study evaluated voice change after open rhinoplasty.

MATERIALS AND METHODS

The present cross-sectional study was conducted on patients undergoing open rhinoplasty. Three acoustic parameters (frequency, bandwidth, and amplitude) were evaluated before open rhinoplasty and then 3, 7, and 10 months after the operation. Patients' sounds when pronouncing M, N, and A were examined. Acoustic factors were measured at the first and second nasal murmurs. Time was a predictive factor and multiple acoustic parameters were the outcome of the study.

RESULTS

Twenty-five patients were studied. Amplitude and bandwidth decreased, whereas frequency increased, when pronouncing the vowel A after rhinoplasty. In contrast, for consonants M and N, amplitude decreased, whereas bandwidth and frequency increased, after rhinoplasty.

CONCLUSION

Open rhinoplasty seems to affect voice quality. Open rhinoplasty altered the frequency, amplitude, and bandwidth of vowel and consonant sounds during 10-month follow-up.
