OBJECTIVES: Vocal fold medialization surgery is generally considered a phonosurgical procedure for improvement of vocal function in patients with glottic insufficiency. However, the literature describing this procedure for the management of dysphagia is limited. This study aims to assess the effects of medialization surgery on swallowing function in patients with unilateral vocal fold paralysis (UVFP). METHODS: We enrolled 32 patients with UVFP undergoing vocal fold medialization surgery (medialization laryngoplasty combined with arytenoid adduction [ML + AA], 12 cases; injection laryngoplasty [IL], 20 cases)...

OBJECTIVES: The paraglottic space is an essential anatomic compartment of the larynx. It is central to the spread of laryngeal cancer and to the choice of conservative laryngeal surgery and many phonosurgical procedures. Since its description, 60 years ago, the surgical anatomy of the paraglottic space was sparsely revisited. Amid the era of endoscopic and transoral microscopic functional surgery of the larynx, we provide here a long-awaited description of the inside-out anatomy of the paraglottic space...

A study group consisted of 103 adult individuals with normal voices (n = 30) and 73 patients with pathological voices...

OBJECTIVE: The aim of the present study is to evaluate the efficacy of phonosurgical corrective approaches based on injection laryngoplasties and pharyngoplasties followed by speech therapy for voice restoration after unsatisfactory phonatory results of open partial horizontal laryngectomies. METHODS: Ten patients with not satisfying phonatory results despite speech therapy after type II or type III open partial horizontal laryngectomies (OPHLs) were included. Each patient underwent a voice restoration program based on phonosurgery (injection laryngoplasty and/or injection pharyngoplasty) with hyaluronic acid and/or calcium hydroxyapatite, followed by post-surgical voice rehabilitation...

Significant and new impulses regarding the treatment concept for outpatient phonosurgery on unsedated patients are currently coming from various Anglo-American authors. These "office-based procedures" have been propagated as an alternative to many conventional surgical interventions under anesthesia. The main reason for this remarkable development is the use of new endoscopic techniques in combination with photoangiolytic laser (KTP and blue laser), which allow safe and efficient phonosurgical procedures. Patient acceptance is high since outpatient procedures are considered to have a lower surgical risk...

OBJECTIVE: The incidence of post-operative glottic cyst (POGC) formation in patients treated with transoral laser microsurgery with potassium-titanyl-phosphate laser (TLM-KTP) photoablation of early glottic carcinoma (EGC) has not previously been described. METHODS: A retrospective chart review was performed to identify all patients with early glottic cancer who underwent with single-modality TLM-KTP at our institution. Each patient received regular follow up with videostroboscopy for tumor surveillance...

Voice diagnostics before and after phonosurgical interventions should aim at detailed planning of surgical techniques and evaluability of postoperative outcome. They should consider multimodal concepts and include measurements of perceptual voice analysis, laryngostroboscopy, voice acoustics, aerodynamics, and self-evaluation by the patients. Selected methods for voice diagnostics should reflect current knowledge and define the departmental procedure.

Laryngeal framework surgery is an umbrella term for all phonosurgical procedures by which the cartilaginous structure of the larynx and thereby the position and tension of the vocal folds are changed. The aim is to improve the voice. By far the best known and most frequently performed operation is thyroplasty type 1 according to Isshiki, also known as medialization thyroplasty, which is indicated for treatment of glottic insufficiency. Although the first medialization thyroplasty was successfully performed by Payr in Germany in 1915, more than 100 years later, it is still not widely used in Germany...

PURPOSE: To evaluate voice quality evolution after a transoral laser cordectomy (TLC) for precancerous lesions and early glottic cancer. METHODS: This prospective study enrolled 18 patients scheduled for TLC for high-grade dysplasia, Tis, T1, and T2 glottic squamous cell cancers, from May 2017 to March 2020. Patients were grouped according to the extent of TLC: Group I (n = 11, 61.1%): unilateral subepithelial or subligamental cordectomy; Group II (n = 7, 38...

PURPOSE: Medialization laryngoplasty can be performed to treat glottic incompetence after endoscopic laser cordectomy. The aim of this study is to evaluate vocal outcome after this phonosurgical procedure and to analyze the critical aspects of the Montgomery and Gore-Tex laryngoplasty technique. METHODS: A retrospective observational study of patients with glottic incompetence after endoscopic laser cordectomy, underwent medialization laryngoplasty with Montgomery or Gore-Tex implant between January 2013 to December 2018 at the Bufalini Hospital of Cesena, Italy...

Benign disease of larynx frequently present with voice disorder. Observing the larynx with high resolution stroboscope and its mucosal wave pattern with greater precision aids in the better understanding of normal/abnormal anatomy and function, which forms the basis of designing treatment strategies.Videolaryngostroboscopy now a days is considered routinely used method of vocal fold examination and evaluation of patients with voice disorders. This valuable imaging tool can also be used to assess the outcomes of therapy of laryngeal diseases or functional result of phonosurgical procedures...

PURPOSE: Arytenoid resection is a well-known intervention to improve glottic airway. Superomedial partial arytenoidectomy (SPA) can also be used for voice improvement by correcting posterior glottic insufficiency in patients with an obstructing anteromedially prolapsed arytenoid. Posterior glottic insufficiency can be difficult to address and traditionally involves challenging arytenoid repositioning procedures. This study aimed to compare postoperative functional voice outcomes in patients who underwent SPA to pre-operative voice status...

Transoral laser microsurgery (TLM) for treatment of laryngeal cancer has reduced temporary tracheotomies, increased organ preservation rates, and improved functional results. Gold standard for laser-based transoral resection of laryngeal cancer is the application of CO2 lasers. Oncologically safe radical resection and postoperative voice outcome must be weighed up individually. Angiolytic laser effects enable modification of the tumor micromilieu by targeted obliteration of microvessels and antagonization of angiogenesis with preservation of vibrating laryngeal tissue for good voice function...

IMPORTANCE: Permanent surgical treatment for unilateral vocal fold paralysis (UVFP) should be performed when further neural recovery is improbable. Conservative delay of the surgical procedure may cause unnecessary deterioration of the patient's quality of life. Knowledge of the natural course of UVFP is important for better management and counseling. OBJECTIVE: To evaluate the natural course of UVFP, focusing on the recovery time according to the injury level to assess the optimal timing for permanent surgical intervention...

There has been rapid growth in the utilization of robotic surgery in the head and neck. Its utilization in the phonosurgical space has lagged owing to difficulty with access and exposure to the laryngeal site, small working space due to the size of the larynx and the need to work around an endotracheal tube. The goal of this work is to explore recent developments in robotic microlaryngeal surgery. At this time robotic instrumentation is available; however, the range of instruments is not as extensive to match the current microlaryngeal instrumentation that exists for traditional endoscopic surgery...

OBJECTIVES/HYPOTHESIS: We previously developed an instrument called the Aerodynamic Vocal Fold Driver (AVFD) for intraoperative magnified assessment of vocal fold (VF) vibration during microlaryngoscopy under general anesthesia. Excised larynx testing showed that the AVFD could provide useful information about the vibratory characteristics of each VF independently. The present investigation expands those findings by testing new iterations of the AVFD during microlaryngoscopy in the canine model...
