Phonosurgical

OBJECTIVE: Although it is known that the airway has bacterial contamination that seeds the surgical site during microlaryngeal surgery, literature on the use of postoperative antibiotics is lacking. We performed a retrospective analysis of open phonosurgical and phonomicrosurgical cases at a single institution to assess whether use of postoperative antibiotics impacts the incidence of surgical site infections (SSI). METHODS: In this retrospective cohort study, we reviewed 228 phonomicrosurgery and 53 open phonosurgery cases performed for benign diseases...

Neocord formation after Type III cordectomy is insufficient for complete glottic closure due to scarring and soft tissue deficit. This study evaluates the role of autologous fat injection (AFI) in phonosurgical management of patients who have previously undergone Type III cordectomy for early glottic cancer. Data was collected from hospital records of patients who underwent AFI after previously undergoing Type III cordectomy. A minimum duration of 6 months post-cordectomy was maintained before fat injection...

PURPOSE: After surgery of vocal folds, almost every patient will need some voice rest. It is common to recommend total silence for some days, followed by less restricted voice use for variable periods. By now, we do not know how voice rest affects the healing process or the current practise in Europe. METHODS: Members of the European Laryngological Society (2012) and the Union of European Phoniatrics (2018) were sent a web-based questionnaire which included two patient cases with a short history and a still picture...

OBJECTIVES: The aim of this study was to assess the feasibility of the submucosal infusion combined with microflap dissection via laser CO2 as both a diagnostic and therapeutic procedure for superficial glottic lesions. To define a safe surgical procedure in terms of local control, a morphometric study of surgical margins was performed. METHODS: From January 2011 to January 2016, we treated 122 patients with early glottic lesions with phonomicrosurgery. Patients with effective hydrodissection underwent a microflap and type I-II diagnostic cordectomy...

In about 20 % of the population older than 60 years of age, voice problems (presbyphonia) are manifest, often combined with hearing deficits (presbyacusis), swallowing disorders (presbyphagia), dizziness (presbyvertigo) and/or impaired vision (presbyopia).The singing voice is afflicted more often, earlier and more severely than the speaking voice. But it is not just the vocal quality and capacity that are affected. Due to reduced pulmonary function, the breathing impetus is also weakened. As a result of the descending of the larynx, resonance properties of the vocal tract change in seniors, and there is increased risk of aspiration...

STUDY DESIGN: Laboratory study, prospective case series. METHODS: The optical efficacy of newly developed rigid 3D endoscopes was examined in a laboratory setting...

The objective of this work is to evaluate the safety, feasibility and efficacy of trans-nasal fiberendoscopic injection laryngoplasty (IL) with centrifuged autologous fat, performed under local anaesthesia, in the treatment of glottic insufficiency due to unilateral vocal fold paralysis (UVFP). It is a within-subject study with follow-up 1 week after phonosurgery and after 6 months. A total of 22 patients with chronic dysphonia caused by glottic insufficiency due to UVFP were enrolled. Each patient underwent trans-nasal IL with centrifuged autologous fat through flexible operative endoscope under local anaesthesia and was evaluated before and twice (1 week and 6 months) after phonosurgery, using a multidimensional set of investigations...

BACKGROUND: Photoangiolytic lasers have broadened the surgical armamentarium for many phonosurgical interventions. However, the pulse dye laser and potassium titanyl phosphate (KTP) laser have technical drawbacks and a smaller spectrum of indications. METHODS AND RESULTS: The new 445 nm wavelength laser, the so-called 'blue laser', proves to show tissue effects comparable to the KTP laser and is also capable of treating subepithelial vessels due to its photoangiolytic properties, it can coagulate and carbonize at higher energy levels, and can be used via glass fibers in non-contact and contact mode for in-office procedures...

PURPOSE: This purpose of this case series is to present the first four cases utilizing micro-phonosurgical instrumentation designed specifically for use with a semi-flexible 'robotic' system-the Medrobotics Flex system and to evaluate the accessibility and feasibility of this platform in the context of transoral robotic surgery (TORS) for laryngeal surgery. METHODS: Four patients (3 female, 1 male; age range 49-79 years) were operated by the senior author at CHL-a tertiary hospital centre between 2016 and 2017...

Glottal insufficiency (GI) is a cause of breathy voice that can profoundly affect quality of voice. Main causes are unilateral vocal fold paralysis or endoscopic cordectomy for the early treatment of laryngeal cancer of the glottis. The main strategy in surgical treatment is type I medialization thyroplasty according to Isshiki with the use of implants e.g. silastic, hydroxyapatite, titanium, Gore-Tex or Montgomery. Other procedures are arytenoid adduction, the injection laryngoplasty via thyrohyoid and cricothyroid approach and laryngeal reinnervation...

OBJECTIVES: The voice range profile (VRP) measures vocal intensity and fundamental frequency. Phonosurgical and logopedic treatment outcome studies using the VRP report voice improvements of 3-6 semitones (ST) in ST range and 4-7 decibels (dB) in sound pressure level range after treatment. These small improvements stress the importance of reliable measurements. The aim was to evaluate the test-retest reliability of the dual-microphone computerized VRP on participants with healthy voices...

OBJECTIVES/HYPOTHESIS: To evaluate gains in microlaryngeal precision achieved by using a novel robotic "steady hand" microsurgery platform in performing simulated phonosurgical tasks. STUDY DESIGN: Crossover comparative study of surgical performance and descriptive analysis of surgeon feedback. METHODS: A novel robotic ear, nose, and throat microsurgery system (REMS) was tested in simulated phonosurgery. Participants navigated a 0...

Objectives Different surgical techniques have been described in the literature to increase vocal pitch. The purpose of this study is to systematically review these surgeries and perform a meta-analysis to determine which technique increases pitch the most. Data Sources CINAHL, Cochrane, Embase, Medline, PubMed, and Science Direct. Review Methods A systematic review and meta-analysis of the literature was performed using the CINAHL, Cochrane, Embase, Medline, PubMed, and Science Direct databases. Studies were eligible for inclusion if they evaluated pitch-elevating phonosurgical techniques in live humans and performed pre- and postoperative acoustic analysis...

Spasmodic dysphonia (SD) is rather a rare voice disorder. It is most often seen in woman aged 40-50. The disease is caused by deep emotional and neurological disorders of extrapyramidal system. Two main clinical forms of SD are distinguished: about 90% of cases - adductor spasmodic dysphonia and abductor spasmodic dysphonia roughly 10%. Conservative therapy does not always yield sufficient effects. Botulinum toxin - type A injections into the thyroarytenoid muscle are also used in therapy. Though results are temporary and reversible...

Surgical treatment of benign vocal fold lesions can be indicated for clinical or functional reasons. The principles of phonosurgery have to be maintained in either case. The appropriate phonosurgical technique depends on the type of vocal fold lesion. Depending on the findings, phonosurgery aims to maintain or improve voice quality. The evaluation of clinical and functional results includes indirect laryngoscopy, videostroboscopy, and voice analysis.

The paper presents a case study of a transsexual patient who underwent a voice pitch elevation surgery performed in Poland for the first time. The human voice is a reflection of the working of hormones and human psyche. This fact is of particular importance in transsexualism, a disorder consisting in incongruence between the individual's biological sex and their identified gender. For many transsexual people, especially of the MTF (male to female) type, who have undergone hormonal and surgical sex change, the voice still presents a major problem, causing difficulties in everyday life...

Altered communication (hoarseness, dysphonia, and breathy voice) that can result from vocal fold paralysis, secondary to numerous etiologies, may be amenable to surgical restoration. In this article, both traditional and cutting-edge phonosurgical procedures targeting the symptoms resulting from vocal fold paralysis are reviewed, with emphasis on the characteristic imaging appearances of various injectable materials, implants, and augmentation procedures used in the treatment of vocal fold paralysis. In addition, complications of injection laryngoplasty and medialization laryngoplasty are illustrated...

OBJECTIVES/HYPOTHESIS: This study was designed to assess the feasibility of the submucosal infusion technique combined with microflap dissection as a radical therapeutic and diagnostic option for precancerous laryngeal leukoplakia. STUDY DESIGN: Retrospective study. METHODS: Severe dysplasia or carcinoma in situ was diagnosed after phonomicrosurgical dissections in 25 patients with unilateral laryngeal leukoplakia.
