Laryngoscope 2018 Dec 13. Epub 2018 Dec 13.

Department of Otorhinolaryngology-Head and Neck Surgery, University of Szeged, Szeged, Hungary.

Objectives/hypothesis: The aim of this study was to analyze the phoniatric and respiratory outcomes of a subset of bilateral vocal cord paralysis (BVCP) patients who were all treated with unilateral endoscopic arytenoid abduction lateropexy (EAAL). EAAL is a nondestructive, minimally invasive glottis widening operation, which does not damage either the surgically treated or the contralateral vocal cord. Therefore, it does not impair the regeneration potential of the recurrent laryngeal nerve. Read More

Otolaryngology Unit, Vittorio Veneto Hospital, Treviso, Italy.

Background: Given the relevance of any tumor invasion of the arytenoid cartilage or crico-arytenoid unit to the planning open partial horizontal laryngectomy (OPHL) for laryngeal squamous cell carcinoma (LSCC), it is important to have a reliable radiological test to assess impairments of these structures.

Methods: We retrospectively compared the endoscopic, radiological, and pathological findings in patients with glottic LSCC who underwent OPHL.

Results: The endoscopic finding of a reduced (impaired or absent) vocal cord motility proved more sensitive, with better positive and negative predictive values, but less specific than the radiological finding of complete arytenoid sclerosis in detecting histologically assessable infiltration of the arytenoid cartilage.

Mayo Clinic Department of Anesthesiology and Perioperative Medicine, Rochester, MN, USA.

Introduction: Type I thyroplasty, or medialization larygoplasty (ML), is a procedure which improves the voice by medializing a vocal fold with a permanent implant. Anesthetic management of these cases is challenging because patients can require periods of deep sedation followed by fully awake moments for phonation to assess the implant size. We present our experience of ML with or without arytenoid adduction (AA) using a multimodal anesthetic regimen consisting of concurrent infusions of dexmedetomidine, remifentanil, and propofol.

Introduction: Dyspnea caused by bilateral vocal cord paralysis often requires surgical intervention to prevent acute asphyxiation. The regeneration of the laryngeal nerves may last weeks or months and it is difficult to predict the outcome. In the past decades, several open and endoscopic surgical techniques have been introduced for treatment to avoid tracheostomy, however, these procedures with resection of the glottis resulted in irreversible changes in the laryngeal structure, thus the voice quality decreased over a long-term period.

Introduction: Bilateral vocal folds' immobility is a challenge in laryngology. Multiple procedures have been proposed to improve breathing by statically enlarging the glottal airway, what also results in loss of voice and aspiration. We proposed a technique to enlarge the posterior glottis by rotating the arytenoids on its axis, imitating the function of the posterior cricoarytenoid muscle, with the objective of evaluating the results regarding decannulation, voice quality, and bronchoaspiration.

Background: The purpose of this retrospective study was to identify subcategories in cT3 to cT4a supraglottic/glottic cancers, describing their different spreading patterns, and local and locoregional recurrence modes.

Methods: Four hundred eighty-nine patients who underwent open partial horizontal laryngectomies (OPHLs) were retrospectively classified as: subcategory I (anterior pT3 with normal arytenoid mobility); subcategory II (posterior pT3 with impaired/absent mobility); subcategory III (anterior pT4 with normal mobility); and subcategory IV (posterior pT4 with impaired/absent mobility).

Results: Five-year overall survival (OS), disease-specific survival (DSS), disease-free survival (DFS), locoregional, local control, freedom from laryngectomy, and laryngectomy-free survival were significantly better in anterior tumors (subcategories I and III) when compared with the corresponding posterior ones (subcategories II and IV).
