Voice disorders among the professional voice users / Шинэ санаа Шинэ нээлт

In modern society there is an increasing demand for oral communication in many professions. Professional voice users aren’t limited to teachers, ministers, salesmen, telemarketers, telephone operators, actors, singers, radio/TV announcers and attorneys. Problems reported by professional voice users are varied and may include hoarseness, voice breaks or cracks, voice loss, weak voiceand vocal fatigue. There are no studies done about the professional voice users in Mongolia. The purpose of this research that was to examine loading effect of work and additional loading factors. We were studied about comparison between normal groups and voice changes groups. Ninety seven professional voice users participated in this study. Half had singers group and half were found to haveteachers group. We used to the voice handicap index (VHI ) score and videolaryngoscopy and other general questionnaire.We studies voice change of the 97 professional voice users. We diagnosed voice disoeders by videolaryngoscopy and voice handicap index. We collected the data base in SPSS 22 and Microsoft excel programs.Major risk factor for voice change was use hormonal medicine. From 97 patients were predominantly diagnosed disease 14,4% reflux laryngit, 15.5% vocal fold nodule, 23.7% acute laryngit. Most of the patients had mild levels changes of voice handicap index.Voice disorders are common in professional voice users. So steroid use increase the risk of voice disorder in professional voice users.

Voice-related Outcome after Thyroidectomy / 대한내분비외과학회지

PURPOSE: Vocal symptoms have been reported after thyroidectomy and even in the absence of injury to the recurrent laryngeal nerve or the external branch of the superior laryngeal nerve. The aim of this prospective study was to evaluate the subjective and objective voice changes in patients without laryngeal nerve injury after thyroidectomy. METHODS: The subjects had undergone total thyroidectomy for differentiated thyroid carcinoma from November 2007 to December 2008. Twenty-eight subjects (males: 8, females: 20) were selected for this study. Voice analysis was prospectively evaluated in the subjects at the time of preoperation and postoperation (10.8 months for the males and 11.7 months for the females). A subjective analysis was done using the visual analogue scale (VAS, 0: no symptom, 10: severe symptoms) and objective analyses were determined by several parameters such as the fundamental frequency (Fo), jitter, shimmer and the noise to harmonic ratio (NHR) using the multi-dimensional voice program. Maximum phonation time (MPT)was performed as an aerodynamic test. RESULTS: 3 patients (37.5%) among the males and 14 patients (70%) among the females had subjective postoperative voice change. The VAS showed a significant difference for the females (0 to 1.25±0.97, P0.05). The vocal parameters (Fo, jitter, shimmer, NHR) and MPT showed no significant changes for both the males and females (P>0.05). CONCLUSION: Subjective voice changes may occur after thyroidectomy without laryngeal nerve injury. Surgeons should take possible voice changes into consideration when informing patients before thyroidectomy.

The Correlation of Tongue Position with Voice / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: The tongue acts as a swallowing moderator, articulator and resonance maker. The tongue may also affect voice production. Authors tried to determine the relationship between the tongue position and voice changes, MATERIALS AND METHODS: Fifty normal subjects (male : female is 23: 27, Group A) between the ages of 20 and 30 years, and 40 subjects (male : female is 20: 28, Group B) with abnormal position of tongue (eg. ankyloglossia) between the ages of 20 and 40 years participated in this study. Subjects were asked about the history of hyperfunctional laryngeal disorders, such as, voice fatigue, frequent voice changes, odynophonia and globus symptoms. Afterwards, we made sure whether the tongue protruded over the lower lip, whether the tip had dimple shape when subject protruded the tongue, whether examiners grasped the tongue easily during laryngeal examination, and whether examiners could see the larynx easily during laryngeal examination or not. At last, concomitant laryngeal disorders were evaluated. RESULTS: The symptoms of hyperfunctional laryngeal disorders were more frequent in the group B. Abnormal tongue movements and functional laryngeal disorders were also more frequent in the group B. CONCLUSIONS: These findings suggest that limited tongue movements may affect voice changes.

Effects of Endoscopic Sinus Surgery on Nasality / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: When the impairment of nasal airway patency in patients with chronic sinusitis such as mucosal edema or nasal polyps is resolved after functional endoscopic sinus surgery (FESS), it is expected that patients no longer complain of hyponasal voice. However, patients who have undergone FESS sometimes complain of more hyponasal voice, or thick voice. The purpose of this study was to examine the effect of FESS on voice in terms of nasality. MATERIALS AND METHODS: Thirty-three patients who underwent FESS and thirty normal adults who had no sinus or nasal pathology were selected for this study. We performed nasalance test for patients group before and 3 months after the operation and for the control group without any medication. RESULTS: Patients' preoperative mean nasalance were not low compared with that of control group in all sentences. It was different from perceptual hyponasality they had complained. Postoperative mean nasalance in patients showed statistically significant increase. Higher change ratio of nasalance was noted in Mamma passage than the other passages. CONCLUSION: There was significant increase in nasalance scores after FESS. Thus, we must consider the possibility of voice changes postoperatively in professional voice users.
