Autologous Fat Plus Platelet-Rich Plasma versus Autologous Fat Alone on Sulcus Vocalis.

Sulcus vocalis is a frequent cause of glottic insufficiency that leads to incomplete vocal fold closure during phonation. Type II sulcus vocalis is defined as a partial defect of the lamina propria (LP). Treatment with fillers, such as fat or hyaluronic acid (HA), in the vocal folds is widely used, but the duration of effect is variable.

Esophageal Pressure and Clinical Assessments in the Gastroesophageal Reflux Disease Patients with Laryngopharyngeal Reflux Disease.

Laryngopharyngeal reflux disease (LPRD) might be associated with reflux symptoms, and its severity is correlated with the Reflux Symptoms Index. Diagnosis is often challenging because of a lack of accurate diagnostic tools. Although an association between LPRD and gastroesophageal reflux disease (GERD) exists, the extent to which esophageal pressure changes in patients with LPRD with GERD has been unknown.

Autologous Fat Injection Laryngoplasty for Unilateral Vocal Fold Paralysis.

Background: Unilateral vocal palsy (UVFP) affects the voice and swallowing function and could be treated by various materials to achieve improved mucosal wave and better closure during phonation. Injection laryngoplasty is considered an exemplary method for these patients and could be injected as early as possible. We conducted a systematic review and meta-analysis for the subjective and objective outcomes of autologous fat injection laryngoplasty (AFIL) and assessed the effects for patients with UVFP.

Comparison Between Combination of Resonant Voice Therapy and Vocal Hygiene Education and Vocal Hygiene Education Only for Female Elementary School Teachers.

Objective: The study compares the rehabilitation outcome of two voice intervention methods for female elementary school teachers with self-reported voice disorders.

Methods: A total of 34 female teachers from two primary schools volunteered in the study. Participants from one school were assigned to the experimental group (16 teachers), who received the combination of vocal hygiene education and resonant voice therapy.

Voice Therapy for Benign Voice Disorders in the Elderly: A Randomized Controlled Trial Comparing Telepractice and Conventional Face-to-Face Therapy.

Purpose Previous studies have reported that voice therapy via telepractice is useful for patients with nodules and muscle tension dysphonia. Nevertheless, telepractice for elderly patients with voice disorders has not yet been investigated. We conducted this study to examine the hypothesis that voice therapy via telepractice is not inferior to conventional voice therapy.

Long-term outcomes of trans-oral robotic surgery-assisted total laryngectomy for recurrent laryngeal cancers.

Objective: For recurrent laryngeal cancers, trans-oral robotic surgery has been used to perform total laryngectomy, but limited cases had been reported without long-term outcome follow-up. This study aims at presenting the largest longitudinal retrospective cohort in a single tertiary referral medical center.

Methods: From November 2013 to August 2017, seven patients with recurrent laryngeal cancers without evidence of neck metastasis were selected to receive trans-oral robotic surgery-assisted TL without neck dissection.

Impact of patient-related factors on successful autologous fat injection laryngoplasty in thyroid surgical treated related unilateral vocal fold paralysis- observational study.

The aim of this study was to compare major voice indicators in different sub-categories, the outcome of lipoinjection for patients might be refined and some voice prognostic factors could be more particularized in specific sub-groups. This is an observational study, and sub-grouped UVFP patients into 3 categories: male vs female, BMI ≥ 24 vs BMI < 24, Age ≥ 60 vs Age < 60 for more detailed exploring whether sub-categories affected voice diagnostic and prognostic parameters. Patients' voice data is recorded before and after the autologous fat injection laryngoplasty by a multidimensional voice program.

Correlation Between Acoustic Measurements and Self-Reported Voice Disorders Among Female Teachers.

Objective: Many studies focused on teachers' voice problems and most of them were conducted using questionnaires, whereas little research has investigated the relationship between self-reported voice disorders and objective quantification of voice. This study intends to explore the relationship of acoustic measurements according to self-reported symptoms and its predictive value of future dysphonia.

Study Design: This is a case-control study.

Risk factors and effects of voice problems for teachers.

The objective of this study was to investigate risk factors of voice problems for teachers with voice disorders as compared to teachers without voice disorders. Many studies have reported risk factors and effects of teachers' voice problems from different professions. Few researchers have investigated these phenomena among people of the same occupation.

Early radiation effects on tongue function for patients with nasopharyngeal carcinoma: a preliminary study.

The purpose of this study was to investigate early radiation effects on tongue function for patients with nasopharyngeal carcinoma (NPC) and to provide a scientific database for early intervention plans. Twelve subjects with NPC and 12 age- and sex-matched normal subjects were included. Tongue maximum isometric strength and endurance at 50% of maximum strength were obtained once from normal subjects with the Iowa Oral Performance Instrument (IOPI) and twice from the NPC subjects: before and 2 months after radiation treatment.

Voice range profiles for tonal dialect of Min.

The influence of frequency and intensity in Min dialect on maximum vocal performance has not been investigated. The purposes of this study are (1) to investigate the physiological frequency and intensity ranges of the tonal dialect of Min, and (2) to compare the physiological frequency and intensity ranges of Min to those of nontonal languages. The subjects were 40 normal Taiwanese adults.

Sex differences in frequency and intensity in reading and voice range profiles for Taiwanese adult speakers.

The purposes of the study were to (1) compare speaking frequency and speaking intensity between normal adult Taiwanese females and males, and (2) compare the physiological frequency and physiological intensity between normal adult Taiwanese females and males. Forty normal young Taiwanese females and 40 males were selected for study. The frequency and intensity variables in reading and in vocal range profiles were collected and analyzed.

Outcome of resonant voice therapy for female teachers with voice disorders: perceptual, physiological, acoustic, aerodynamic, and functional measurements.

Teachers have a high percentage of voice problems. For voice disordered teachers, resonant voice therapy is hypothesized to reduce voice problems. No research has been done on the physiological, acoustic, and aerodynamic effects of resonant voice therapy for school teachers.

Impact of topical anesthesia on acoustic characteristics of voice during laryngeal telescopic examination.

Objective: The purposes of this study are to investigate the impact of topical anesthetic alone and with concurrent laryngeal telescopic examination on acoustic characteristics of vocal fold function. Comparison with phonation in controlled conditions may imply diagnostic information from the examination.

Study Design: Thirty males evaluated as having a normal voice were included in the study.
