A proposal for needle projections in transcutaneous injection laryngoplasty using three-dimensionally reconstructed CT scans.

Surg Radiol Anat 2021 Aug 2;43(8):1225-1233. Epub 2021 Jan 2.

Department of Radiology, Universiti Kebangsaan Malaysia Medical Centre, Jalan Yaacob Latif, Bandar Tun Razak, 56000, Kuala Lumpur, Malaysia.

Purpose: This study aims to determine laryngeal dimension in relation to all three transcutaneous injection laryngoplasty (TIL) approaches (thyrohyoid, transthyroid and cricothyroid) using three-dimensionally reconstructed Computed Tomography (CT) scan and compare the measurements between sex, age group and ethnicity.

Methods: CT scans of the neck of two hundred patients were analysed by two groups of raters. For thyrohyoid approach, mean distance from the superior border of the thyroid cartilage to the laryngeal cavity (THd) and mean angle from the superior border of the thyroid cartilage to mid-true cords (THa) were measured.

Department of Otorhinolaryngology-Head and Neck Surgery, Seoul National University Hospital, Seoul, South Korea. Electronic address:

Objectives: In pediatric airway surgery, SponTaneous Respiration using IntraVEnous anesthesia and Hi-flow nasal oxygen (STRIVE Hi) has not been well explored. Here, we report our experience of using STRIVE Hi in endoscopic evaluations and surgeries of the pediatric airway.

Methods: This retrospective review was based on 45 airway procedures conducted under STRIVE Hi, performed by a single surgeon at a single institute from May 2017 to September 2018. Read More

Anatomical Study of Two Cricothyroid Approaches to the Cadaver Larynx.

J Voice 2021 May 27;35(3):360-364. Epub 2019 Dec 27.

Department of Otolaryngology-Head and Neck Surgery, Drexel University College of Medicine, Philadelphia, Pennsylvania; Lankenau Institute for Medical Research, Wynnewood, Pennsylvania. Electronic address:

Objective: The purpose of this study was to measure the angle and depth at which the vocal folds are accessed via transcutaneous injection through two different approaches through the cricothyroid membrane.

Methods: Twenty-five cadavers preserved with formalin were studied. The larynges were bisected through the thyroid notch, and the skin and soft tissue were removed. Read More

Early Injection Laryngoplasty After Surgery: 30 Cases and Proposed Aspiration Assessment Protocol.

J Voice 2020 Jan 16;34(1):121-126. Epub 2018 Oct 16.

Department of Otolaryngology-Head and Neck Surgery, Stanford University School of Medicine, Stanford, CA. Electronic address:

Vocal fold movement impairment may significantly compromise postoperative recovery and quality of life of patients following thoracic or cardiothoracic surgery or prolonged intubation. The literature is limited and there is no standard screening protocol for the optimal postoperative swallowing and aspiration evaluations. We performed retrospective review of adult patients undergoing early vocal fold (VF) injection laryngoplasty for acute postoperative Vocal fold movement impairment (<30 days) that had both pre- and postinjection speech language pathologist (SLP) performed swallowing/aspiration evaluations.

Injection laryngoplasty through a transoral approach using the Guedel oral airway.

Acta Otorhinolaryngol Ital 2017 Oct;37(5):444-446

Department of Otolaryngology, Head & Neck Surgery, American University of Beirut Medical Center, Beirut- Lebanon.

Injection laryngoplasty has gained popularity as a treatment modality for glottal insufficiency. Several approaches have been described, specifically transcutaneous, transoral and transnasal. The authors describe a novel technique performed successfully on three subjects, namely endoscopic injection laryngoplasty using the modified Guedel oral airway. Read More

Development of a device for real-time light-guided vocal fold injection: A preliminary report.

Laryngoscope 2016 Apr 25;126(4):936-40. Epub 2015 Sep 25.

Department of Otorhinolaryngology-Head and Neck Surgery, Pusan National University Hospital, Busan, Korea.

Objectives/hypothesis: Vocal fold injection is a minimally invasive technique for various vocal fold pathologies. The shortcomings of the cricothyroid (CT) membrane approach are mainly related to invisibility of the injection needle. If localization of the needle tip can be improved during vocal fold injection with the CT approach, the current problems of the technique can be overcome. Read More

Posterior glottic gap and age as factors predicting voice outcome of injection laryngoplasty in patients with unilateral vocal fold paralysis.

J Laryngol Otol 2012 Mar 6;126(3):260-6. Epub 2011 Oct 6.

Department of Otorhinolaryngology - Head and Neck Surgery, Sungkyunkwan University School of Medicine, Samsung Medical Center, Seoul, South Korea.

Objectives: This study aimed to analyse demographic profiles and pre-injection stroboscopic findings for patients with unilateral vocal fold paralysis, to investigate possible predictive factors for voice outcomes of injection laryngoplasty.

Materials And Methods: Fifty-nine unilateral vocal fold paralysis patients underwent vocal fold augmentation, using transcutaneous Artecoll (polymethyl methacrylate microspheres plus bovine collagen) injection into the paralysed vocal fold via the cricothyroid space. Three months later, patients were divided into improved (n = 44) and unimproved (n = 15) groups, using the perceptual grade-roughness-breathiness-asthenia-strain scale, and their clinical characteristics and pre-operative stroboscopic findings compared.

Injection laryngoplasty with hyaluronic acid for unilateral vocal cord paralysis. Randomized controlled trial comparing two different particle sizes.

J Voice 2010 Jan 16;24(1):113-8. Epub 2009 Jun 16.

Department of Otolaryngology, Singapore General Hospital, Singapore.

The objective was to determine if particle size affects durability of medialization in patients undergoing injection laryngoplasty (IL) with hyaluronic acid (HA) for unilateral vocal cord paralysis (UVCP). We hypothesized that large particle-size HA (LPHA) persists longer after injection to produce a more durable vocal result. The study design used was a prospective randomized controlled single-blind trial. Read More

Transcutaneous injection laryngoplasty through the cricothyroid space in the sitting position: anatomical information and technique.

Eur Arch Otorhinolaryngol 2008 Mar 25;265(3):313-9. Epub 2007 Sep 25.

Department of Otolaryngology, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, 108, Pyoung-Dong, Jongro-Ku, 110-746 Seoul, South Korea.

A variety of approaches have been introduced to perform injection laryngoplasty under local anesthesia. Among these reported methods, transcutaneous injection through the cricothyroid space offers many advantages, but it possesses some technical difficulties during access to the vocal fold. The aim of this study was to assess the anatomic references related to transcutaneous injection laryngoplasty through cricothyroid space using 3-dimensionally reconstructed computed tomography to provide guidelines and to achieve higher efficacy during the procedure.

Early results of transcutaneous injection laryngoplasty with micronized acellular dermis versus type-I thyroplasty for glottic incompetence dysphonia due to unilateral vocal fold paralysis.

J Voice 2003 Dec;17(4):589-95

University of Miami School of Medicine, The Department of Otolaryngology, Miami, Florida 33101, USA.

Medialization thyroplasty (type I) has become the gold standard to improve glottic closure due to unilateral vocal fold paralysis. A newer injection method utilizing homologous collagen from cadaveric human tissue has been described as an attractive alternative as no donor site is required, there is a very low risk of hypersensitivity, and the intact, acellular collagen fibers may suffer a reduced long-term reabsorption rate. Preliminary results on eight patients comparing presurgical and postsurgical parameters (perceptual, stroboscopic, acoustic, and aerodynamic) revealed comparable results when compared with a control group of individuals, age- and sex-matched, that had undergone standard medialization thyroplasty (type I).
