Phonomicrosurgery

Objective: To analyze the effects of lingual frenotomy on adults with restrictive ankyloglossia and difficult direct laryngoscopy exposure. Methods: A case series study was conducted. Restriction of tongue protrusion due to ankyloglossia was identified in 2 patients who had a history of suboptimal true vocal fold (TVF) exposure on direct laryngoscopy for phonomicrosurgery. Inadequate exposure of the vocal folds was achieved on direct laryngoscopy attempts with manual tongue protrusion. Mandibular tori were not present in these patients...

OBJECTIVES: Voice rest is commonly recommended for patients with benign vocal fold lesions (BVFLs) after phonomicrosurgery. The study compares the clinical voice outcomes of two protocols, 7-day complete voice rest (CVR) and 3-day CVR followed by 4-day relative voice rest (CVR + RVR), for patients with BVFLs after phonomicrosurgery. STUDY DESIGN: Prospective, randomized controlled trial. METHOD: Patients with BVFLs undergoing phonomicrosurgery were recruited prospectively and randomly assigned to either protocol...

OBJECTIVES: To elucidate recurrence patterns of Reinke's edema (RE) following phonomicrosurgery and compare current and former smokers' outcomes. METHODS: A retrospective chart review was performed for patients who underwent microflap excision for RE at our institution since 2008. Patient data were collected, including demographics, smoking history, and operative and voice outcomes during the available follow-up period. Descriptive statistics, student's t-tests, Chi-squared analyses, and Fischer's exact tests were used for the appropriate between-group comparisons utilizing JMP statistical software...

Vocal arts medicine provides care and prevention strategies for professional voice disorders in performing artists. The issue of correct "Fach" determination depending on the presence of a lyric or dramatic voice structure is of crucial importance for opera singers, as chronic overuse often leads to vocal fold damage. To avoid phonomicrosurgery or prevent a premature career end, our aim is to offer singers an improved, objective fach counseling using digital sound analyses and machine learning procedures. For this purpose, a large database of 2004 sound samples from professional opera singers was compiled...

OBJECTIVE(S): Voice rest is commonly recommended following phonomicrosurgery to minimize vocal fold scarring, but associated quality of life (QoL) is low resulting in poor compliance. This study aimed to explore patients' experiences with voice rest following phonomicrosurgery to identify facilitators and barriers. METHODS: This qualitative study used prospective, typical case technique for purposive sampling of consecutive patients who underwent voice rest following phonomicrosurgery for benign vocal fold lesions...

OBJECTIVE: This study aims to create a synthetic laryngeal microsurgery simulation model and training program; to assess its face, content, and construct validity; and to review the available phonomicrosurgery simulation models in the literature. STUDY DESIGN: Nonrandomly assigned control study. SETTING: Simulation training course for the otolaryngology residency program at Pontificia Universidad Católica de Chile. METHODS: Resident (postgraduate year 1 [PGY1]/PGY2) and expert groups were recruited...

OBJECTIVES: Vocal fold nodules (VFNs) are bilateral, mid-membranous, swellings of the vocal folds. Intralesional steroid injection was successfully tried in the management of benign vocal fold lesions including nodules. The aim of the present study was to compare treatment outcomes of vocal fold steroid injection (VFSI) and surgery in patients with VFNs in terms of lesion regression, subjective, and objective voice parameters. STUDY DESIGN: Nonrandomized controlled clinical trial...

INTRODUCTION: Mucosal Bridges (MBs) are defined as benign connective tissue abnormalities of unclear etiology that extend over the free surface of the vocal fold, are attached to the front and back of the vocal fold but are not attached to its free surface, and are histologically covered by stratified squamous epithelium. In order to overcome these drawbacks, we aimed to retrospectively evaluate and present the preoperative and postoperative results of patients with MB, who were applied the method we call "Mucosal Bridge Reconstruction" (MBR), which we apply as suturing rather than resection of the MB...

OBJECTIVE: To present and validate a new simulation model for endoscopic phonomicrosurgery training as an improved teaching method. METHODS: A low-cost artificial model was assembled using 3D printing, silicone, and gelatin. The study was designed to test the model's ability to carry out training and teaching of endoscopic phonomicrosurgery. The synthetic model was built to simulate normal and pathological vocal folds such as polyps, intracordal cysts and keratoses, made of silicone and gelatin and embedded in a larynx framework made by 3D printing...

PURPOSE: Voice change is one of the major symptoms in patients with vocal fold polyp. As a result, phonomicrosurgery is commonly required in these patients. Since voice outcomes after polyp treatment can be variable according to polyp characteristics, we aimed to investigate the predicting factors of postoperative voice improvements in terms of polyp characteristics in patients with vocal fold polyp who underwent cold knife surgery. MATERIALS AND METHODS: A total of 77 patients who were diagnosed with vocal fold polyp and underwent phonomicrosurgery with cold knife instruments...

Laser microsurgery is the current gold standard surgical technique for the treatment of selected diseases in delicate organs such as the larynx. However, the operations require large surgical expertise and dexterity, and face significant limitations imposed by available technology, such as the requirement for direct line of sight to the surgical field, restricted access, and direct manual control of the surgical instruments. To change this status quo, the European project μRALP pioneered research towards a complete redesign of current laser microsurgery systems, focusing on the development of robotic micro-technologies to enable endoscopic operations...

OBJECTIVES: The purpose of this study was to the usefulness of a five-variable model predicting perceived voice severity and incorporating acoustic analysis based on cepstral analysis and self-reported questionnaires, for measuring voice recovery after endolaryngeal phonomicrosurgery in patients with vocal fold polyps. METHODS: In this study, 72 patients with vocal fold polyps were included. Two voice evaluations, including acoustic analysis, self-reported questionnaires, and auditory perceptual assessments for each patient, were implemented before and after endolaryngeal phonomicrosurgery...

Between 2006 and 2016 in a Tertiary Academic Center, 11 patients underwent phonomicrosurgery with tragal perichondrium graft placement in Reinke's space for the treatment of sulcus (Ford type 2) and vocal fold scar. A total of six patients out of 11 had an additional autologous fat implantation in order to improve the glottic closure. We evaluated the functional outcome using the Spanish validated version of the VHI- 30 before and 6 months after the surgery. We also measured the subjective appreciation of the obtained outcome, a perceptual voice evaluation using GRBAS scale, and changes in videostroboscopy examinations concerning mucosal wave and glottic closure...

OBJECTIVES: Current treatments for benign vocal lesions consist mainly voice therapy and phonomicrosurgery. However, these options are not always suitable for professional voice users because of their tight performance schedule and limited time for voice rest. This study investigated vocal fold steroid injection (VFSI) as an alternative treatment. STUDY DESIGN: Matched case series. METHODS: We retrospectively enrolled 28 professional voice users (i...

INTRODUCTION: Phonomicrolaryngeal surgery involves the surgical treatment of benign disorders of the vocal folds. Postoperative scar tissue in vocal fold mucosa is undesired because mucosal hypodynamia may lead to prolonged impairment in voice quality. This study aims to present and share the outcomes of a new endolaryngeal suture technique. METHODS: This study consists of patients who underwent vocal fold surgery followed by endolaryngeal microscopic suturation with a technique that we call the "mini-microsuture technique" between January 2018-December 2019...

OBJECTIVES: The objective of this study was to present a novel surgical technique involving the use of a "bipedicled vocal fold mucosal flap" to repair a mucosal defect and to evaluate the outcomes of patients in whom it was used. MATERIAL AND METHODS: This was a retrospective study of 6 clinical cases. All patients underwent surgery between November 2000 and July 2018, and all procedures were performed by the same surgeon. For the auditory-perceptual assessment, the Grade-Roughness-Breathiness-Asthenia-Strain hoarseness scale was used...

INTRODUCTION: Semi-occluded vocal tract exercises, such as water resistance therapy (WRT), are widely used in voice therapy. However, the potential positive effects of such a therapy on vocal fold oscillation patterns in patients indicating a need for phonomicrosurgery have not yet been explored. The presented study aims to analyze the effect of WRT in patients suffering from vocal fold mass lesions. MATERIALS AND METHODS: Eight participants with vocal fold mass lesions were asked to sustain a phonation on the vowel /i/ at a comfortable loudness and a fundamental frequency of 250 Hz (females) or 125 Hz (males)...

Vocal fold polyp (VFP) is an exophytic gelatinous lesion with an atrophic epithelium. After behavioral and conservative management, phonomicrosurgery is the treatment of choice for VFPs with excellent outcomes in terms of lesion resolution and postoperative vocal function. Office-based potassium titanyl phosphate (KTP) laser ablation is a new treatment modality for VFPs but its efficacy for professional singers has yet to be validated. Reported is a consecutive series of six professional singers (with seven episodes of VFP) who, based on patient and provider preference, underwent in-office KTP laser ablation of VFP...

OBJECTIVES: To compare continuous (C-IONM) vs intermittent intraoperative neuromonitoring (I-IONM) in complex benign thyroid surgery, and to follow up patients with loss of signal (LOS) or unilateral vocal fold paralysis (UVFP). DESIGN: Retrospective clinical study, prospective case series. SETTING: University hospital and academic teaching hospital of Charité-University Medicine Berlin, Germany. PARTICIPANTS: C-IONM- and I-IONM-assisted thyroid surgery was conducted in 357 patients diagnosed with recurrent goitre, Graves' disease, complex hyperparathyroidism, cervical preoperation (anterior access) and LOS in primary operation (2-stage thyroidectomy)...

OBJECTIVE: To investigate the presence of sulcus vocalis in patients who underwent phonomicrosurgery due to benign vocal cord lesions. METHODS: Between January 2013 and June 2018, the records of 133 patients who underwent operations for benign vocal fold pathology were retrospectively reviewed. Intraoperative findings of the patients were noted. Patients were divided into two groups: patients with only benign vocal fold lesions (BVFL) and patients with benign vocal fold lesions and accompanying sulcus vocalis (SV + BVFL)...
