Item type:Publication, Objective Voice Analysis of Mongolian Adults with a Normal Voice Across Age and Gender(Mongolian National University of Medical Sciences, 2021-07-01); ; Objectives: We aimed to standardize main vocal parameters including fundamental frequency (F0), jitter, shimmer, harmonic-noise ratio (HNR), and smoothed cepstral peak prominence (CPPs) for Mongolian adults with a normal voice across a range of age groups and genders. Methods: A total of 360 voice recordings belonging to adults between 20 and 79 years old were analyzed. An acoustic analysis was performed using the Praat Program with a sustained vowel /a/ or /α/. A one-way analysis of variance and an unpaired t-test were used to measure differences in voice parameters for the age groups and genders. Results: The mean value of F0 was higher in women (254.4 ± 17.9 Hz) compared with men (149.6 ± 15.3 Hz). The average jitter was 0.26% ± 0.12% (W = 0.25 ± 0.13) and the shimmer was 1.95% ± 0.45% (W = 2.01% ± 0.45%). The mean value of HNR was 11.9 ± 1.33 dB (W = 12.1 ± 1.36 dB) and CPPs was 16.3 dB (W = 16.1 dB). Conclusion: The F0 and HNR significantly increased with age for men. The F0 and CPPs decreased, whereas the shimmer and HNR increased with age in women. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Acoustic Outcomes Comparison Injection Versus Medialization Laryngoplasty(Mongolian National University of Medical Sciences, 2020-06-25); ; Objectives: To determine whether injection laryngoplasty or medialization thyroplasty is more effective in the treatment of unilateral vocal fold paralysis. Methods: A prospective study of 75 patients with unilateral vocal cord paralysis who underwent autologous fat injection laryngoplasty or medialization laryngoplasty at the First Central Hospital of Mongolia between 15th Nov 2016 and 15th Jan 2020. The data analyzed included patient characteristics and type of intervention, along with the before treatment, 1 and 6 months after treatment voice parameters of electrogIottography and patients' subjective voice assessment. Results: Seventy-five patients were evaluated. The average time from intervention to post-treatment evaluation was 1 and 6 months. Improvements were demonstrated in all voice parameters (Maximum Foniation Time, Jitter, Shimmer, and Harmonic Noise Ratio) in both the injection and the medialization groups. Conclusions: In this study, objective and subjective voice analysis confirmed that injection and medialization laryngoplasty were effective in unilateral vocal cord paralysis. Both of these methods can be used to treat unilateral vocal cord paralysis. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Дууны хөвчийн саажилтын шалтгаан(2019-11-18); Л.БямбасүрэнBackground: Vocal cord paralysis is a common symptom of numerous diseases and it may be due to neurogenic or mechanical fixation of the cords. Paralysis of the vocal cords is just a symptom of underlying disease in some cases so, clinical diagnosis of the underlying cause leading to paralysis of the vocal cords is important. This study evaluates the causes of vocal cord paralysis. Materials and Methods: In a prospective study, 45 patients with paralyzed vocal cord diagnosis were examined by tests such as examination of the pharynx, larynx, esophagus, thyroid, cervical, lung, and mediastinum, brain and heart by diagnostic imaging to investigate the cause vocal cord paralysis. The study was ended by diagnosing the reason of vocal cord paralysis at each stage of the examination and the clinical studies. Results: The reason for referral was phonation changes 96% and aspiration 57% in the subjects. There was bilateral paralysis in 6.4%, left paralysis in 57.4% and right in 36.1% of subjects. The type of vocal cord placement was median in 44.8%, paramedian in 38.2%, intermedian in 10.6% and lateral in 6.4% of the subjects. The causes of vocal cords paralysis were idiopathic paralysis 8 (17%), tumors 9 (19.1%), surgery 28 (59%), lung tuberculosis 2 (4%). Conclusion: Vocal cord paralysis after thyroidectomy is common that is thyroid surgery so late, we need neiromonitor during thyroidectomy in our country. Possibility of malignancy should be excluded before marking idiopathic reason to vocal cord paralysis. - Some of the metrics are blocked by yourconsent settings
