JAMA Otolaryngol Head Neck Surg 2021 Jun 10. Epub 2021 Jun 10.

School of Communication Sciences and Disorders, McGill University, Montreal, Canada.

Importance: Vocal fold paralysis (VFP) results from the disruption of neural motor outputs to laryngeal muscles. Children with VFP manifest various degrees of difficulties in phonation, breathing, and swallowing. Although the etiologic characteristics and symptoms of VFP are well established in adults, corresponding clinical profiles are notably different in children. Read More

Effects of Superomedial Partial Arytenoidectomy on Incomplete Posterior Glottal Closure Caused by Arytenoid Positional Asymmetry in Excised Human Larynges.

J Voice 2021 Jun 6. Epub 2021 Jun 6.

From the Department of Otolaryngology, University of Sao Paulo School of Medicine, Sao Paulo, Brazil.

Objectives: To analyze the effects that arytenoid positional asymmetry has on posterior glottic closure and to determine whether superomedial partial arytenoidectomy (SPA) can provide a benefit in cases of such asymmetry.

Methods: In this experimental study, we evaluated posterior glottic closure in 10 larynges freshly excised from human cadavers, measuring the distance between the vocal processes before and after artificially simulated positional asymmetry of the arytenoid cartilages. We then performed SPA, after which we again measured the distance between the vocal processes. Read More

The role of imaging in the evaluation of hoarseness: A review.

Vikas Jain

J Neuroimaging 2021 May 20. Epub 2021 May 20.

Radiology Department, MetroHealth Medical Center, Case Western Reserve University, Cleveland, Ohio, USA.

Hoarseness is a common symptom indicating an abnormal change in the quality of voice and has a lifetime prevalence of around 30%. There are multiple causes of hoarseness, ranging from acute laryngitis, chronic laryngitis, laryngopharyngeal reflux, functional dysphonia due to vocal overuse or abuse, vocal cord paralysis (VCP), to various pathologies and masses in the larynx. A detailed history and thorough physical examination, and in many cases, laryngoscopy by a clinician are the initial steps in its management. Read More

HNO 2021 May 12. Epub 2021 May 12.

Medical Voice Center, Martinistraße 64, 20251, Hamburg, Deutschland.

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.

Department of Gastroenterological Surgery, Nagoya City University Graduate School of Medical Sciences, Mizuho-cho, 1 Kawasumi, Mizuho-ku, Nagoya, Aichi, Japan.

Advancements in thoracoscopic surgery have provided us with a deeper anatomical understanding of recurrent laryngeal nerve paralysis (RLNP), which is likely to occur after lymph node dissection. Taking a novel approach to researching the diagnosis of RLNP, we evaluated movement of the vocal cords and arytenoid cartilages using ultrasonography in patients who underwent thoracoscopic esophagectomy. RLNP occurred in six of the 24 patient cohort. Read More

Learning to Interpret Pediatric Vocal Fold Mobility: A Laryngeal Ultrasound Training Module.

Laryngoscope 2021 Apr 23. Epub 2021 Apr 23.

Department of Otolaryngology Head and Neck Surgery, Baylor College of Medicine, Texas Children's Hospital, Houston, Texas, U.S.A.

Objectives/hypothesis: Vocal fold movement impairment (VFMI) in infants and children is most commonly evaluated by flexible nasolaryngoscopy (FNL). FNL in this population can be challenging due to movement, floppy supraglottic structures, or secretions. Laryngeal ultrasound (LUS) may be an alternative, less invasive means of evaluating VFMI that also decreases aerosolization during the COVID-19 pandemic. Read More

Tissue-engineering the larynx: Effect of decellularization on human laryngeal framework and the cricoarytenoid joint.

J Biomed Mater Res B Appl Biomater 2021 Apr 19. Epub 2021 Apr 19.

Department of Pharmaceutical Sciences and Experimental Therapeutics, College of Pharmacy, University of Iowa, Iowa City, Iowa, USA.

Decellularization approaches have been commonly used as alternative techniques to reconstruct tissues. However, due to the complex tissue compartmentation of the larynx, the decellularization process may not retain the characteristics necessary for the successful recreation of the larynx. The aim of this study was to assess the effect of the decellularization process on the framework of the human cadaveric larynx generally and the cricoarytenoid joint specifically. Read More

Stereotactic body radiotherapy for T1 glottic cancer: dosimetric data in 27 consecutive patients.

Tumori 2021 Apr 6:3008916211000440. Epub 2021 Apr 6.

Department of Physics, IRCCS Regina Elena National Cancer Institute, Rome, Italy.

Aim: Because the clinical feasibility of stereotactic body radiotherapy (SBRT) for early glottic cancer (T1) is controversial, we report dosimetric results in 27 consecutive patients from a prospective phase I and II study that started in 2017.

Methods: In our approach, only the parts of the true vocal cord containing cancer and those immediately adjacent are planned to be treated to 36 Gy and 30 Gy, respectively, in 3 fractions. Several dosimetric metrics for both target volumes and organs at risk were extracted from individual plans and results were compared to those achieved by other authors in a similar setting.

Fluid-structure-acoustic interactions in an ex vivo porcine phonation model.

J Acoust Soc Am 2021 Mar;149(3):1657

Division of Phoniatrics and Pediatric Audiology at the Department of Otorhinolaryngology, Head and Neck Surgery, University Hospital Erlangen, Medical School at Friedrich-Alexander-Universität Erlangen-Nürnberg, Waldstrasse 1, 91054 Erlangen, Germany.

In the clinic, many diagnostic and therapeutic procedures focus on the oscillation patterns of the vocal folds (VF). Dynamic characteristics of the VFs, such as symmetry, periodicity, and full glottal closure, are considered essential features for healthy phonation. However, the relevance of these individual factors in the complex interaction between the airflow, laryngeal structures, and the resulting acoustics has not yet been quantified. Read More

Department of Otolaryngology Head and Neck Surgery, Taipei Tzu Chi Hospital, Buddist Tzu Chi Medical Foundation, New Taipei City, School of Medicine, Tzu Chi University, Hualien, Taiwan, Republic of China.

Objective: In order to correct the varying vocal fold positions to meet the various clinical requirements in patients with bilateral vocal fold immobility, we present pertinent surgical methods to treat them.

Materials And Methods: From 2005 to 2020, 115 patients diagnosed with bilateral vocal fold immobility were addressed for ventilation in 89 patients and for phonation in 26 patients. In the ventilation surgery group, all the neurogenic subjects received mere suture lateralization (SL) procedures and the mechanical ones underwent arytenoid release (AR) plus SL procedures if the cricoarytenoid joint fixation (CAJF) could be confirmed before operation.

Arytenoid asymmetry: Is it the most predictive parameter for arytenoid adduction in unilateral vocal fold paralysis?

J Laryngol Otol 2021 Feb 17;135(2):159-167. Epub 2021 Feb 17.

Department of Laryngology, Dr Jayakumar's Institute of Laryngology, Trivandrum, India.

Objective: The aim of this study was to establish arytenoid asymmetry as a pre-operative predictive parameter for arytenoid adduction surgery in unilateral vocal fold paralysis and thereafter identify the most predictive parameter for arytenoid adduction among the established parameters.

Methods: A retrospective comparative study was undertaken. The 'arytenoid asymmetry angle' formed between skewed 'glottic' and 'interarytenoid' axes (traced along the plane of closure of the membranous and cartilaginous glottis, respectively) was quantified in pre-operative laryngoscopic images of 85 adults with unilateral vocal fold paralysis who underwent either type 1 thyroplasty (group 1) or type 1 thyroplasty with arytenoid adduction (group 2).
