Purpose: Videostroboscopy (VS) uses an indirect physiological signal to predict the phase of the vocal fold vibratory cycle for sampling. Simulated stroboscopy (SS) extracts the phase of the glottal cycle directly from the changing glottal area in the high-speed videoendoscopy (HSV) image sequence. The purpose of this study is to determine the reliability of SS relative to VS for clinical assessment of vocal fold vibratory function in patients with mass lesions. Methods: VS and SS recordings were obtained from 28 patients with vocal fold mass lesions before and after phonomicrosurgery and 17 controls who were vocally healthy...

OBJECTIVE: Phonomicrosurgery is generally considered to be the treatment of choice for removing vocal fold polyps. However, specific techniques of voice therapy may represent, in selected cases and under certain conditions, a noninvasive therapeutic option for the treatment of such laryngeal lesions. The aim of the present study is to longitudinally assess, in terms of clinical outcomes and quality of life, two groups of patients with cordal polyps, treated either with standard surgery plus standard voice therapy or with a specific training of voice therapy alone, which we have called "Voice Therapy Expulsion...

OBJECTIVES: Voice rest is commonly recommended after phonomicrosurgery to prevent worsening of vocal fold injuries. However, the most effective duration of voice rest is unknown. Recently, early vocal stimulation was recommended as a means to improve wound healing. The purpose of this study is to examine the optimal duration of voice rest after phonomicrosurgery. STUDY DESIGN: Randomized controlled clinical study. METHODS: Patients undergoing phonomicrosurgery for leukoplakia, carcinoma in situ, vocal fold polyp, Reinke's edema, and cyst were chosen...

Herein, we described a novel method as the use of AcuBlade robotic microsurgery system to manage idiopathic subglottic stenosis in a 73 years old lady. Compared to traditional CO2 lasers, AcuBlade facilitated the scar resection by the generation of different shape of beams (straight, curved, or disk). The same setting used for phonomicrosurgery (1-mm beam length, power of 10 W and pulse duration of 0.05-s) allowed to obtain fast, long, and uniform cuts. In addition, the reduction of the number of laser passes over the same area prevented injury of adjacent tissue and thus reduced the risk of recurrence...

OBJECTIVES/HYPOTHESIS: Vocal fold scarring, which causes severe hoarseness, is intractable. The optimal treatment for vocal fold scarring has not been established; therefore, prevention of scarring is important. The aim of this study was to clarify the effectiveness of basic fibroblast growth factor (bFGF) for prevention of postsurgical vocal fold scarring. STUDY DESIGN: Prospective animal experiments with controls. METHOD: The vocal folds of Sprague-Dawley rats were injured unilaterally or bilaterally after local application of a 10 μL solution of bFGF...

OBJECTIVES/HYPOTHESIS: To study the different arm support postures used in phonomicrosurgery by using a magnetic-based phonomicrosurgery instrument tracking system (MPTS). Through quantitative motion parameter data collected from four arm support postures (elbow support [ES], forearm support [FS], forearm and hand support, and no support), phonomicrosurgical operation postures were analyzed and compared. STUDY DESIGN: Prospective cohort study. METHODS: Seven subjects operated on phonomicrosurgical simulation cutting tasks with four arm support postures while being monitored by MPTS...

OBJECTIVES/HYPOTHESIS: Benign midmembranous vocal fold lesions (BMVFLs) are common voice disorders, but interpretation of outcomes following treatment is difficult due to the lack of a standardized nomenclature system for these lesions. Outcome results are increasingly important to third party payers. This study aimed to investigate the outcomes of patients with BMVFLs using a previously validated nomenclature, and to provide incidences and outcome results for each diagnosis. METHODS: A retrospective chart review of BMVFL patients was performed...

OBJECTIVE: The aim of the study was to assess the effect of endolaryngeal phonomicrosurgery (EPM) and voice therapy in patients with vocal fold polyps using perceptual and acoustic analysis before and after both therapies. METHODS: The acoustic tests and perceptual evaluation of voice were carried out on 41 female patients with vocal fold polyp before and after EPM and voice therapy. Both therapy strategies were performed. Used acoustic parameters were Jitter percent (Jitt), pitch perturbation quotient (PPQ), shimmer percent (Shim), amplitude perturbation quotient (APQ), fundamental frequency variation (vF0), noise-to-harmonic ratio (NHR), Voice Turbulence Index (VTI)...

The objective of this study was to evaluate the use of quantum molecular resonance (QMR) energy in phonomicrosurgery. Quantum molecular resonance energy (QMRE) is an innovative technology that provides low temperature cutting and coagulation of tissues and causes minimal tissue damage during the procedure. Because of these features, this technology may offer new possibilities in phonomicrosurgery. Twelve patients with vocal fold polyps underwent QMR-assisted phonomicrosurgery. The patients were evaluated before and after surgery at 1 and 3 months postoperatively by using the voice handicap index, laryngeal stroboscopy rating, acoustic voice analysis, and perceptual voice evaluation...

The objective of the present study was to determine the effect of voice training on the vocal rehabilitation of patients with vocal cords polyps following phonomicrosurgery. A total of 60 cases of vocal cord polyps treated by laser phonomicrosurgery were randomly divided into training and control groups with 30 cases in each group. The patients were treated with laser phonomicrosurgery, routine postoperative treatment and nursing. The training group were additionally treated with vocal training, including relaxation training, breathing training, basic pronunciation training, chewing voice training and tone sandhi pronunciation training, and attention was paid to the training steps...
