Endoscopic Arytenoid Abduction Lateropexy with Endolaryngeal Thread Guide Instrument for Bilateral Vocal Fold Paralysis
2020Co-Authors: Shahram Madani, Ádám Bach, Gholam Hossein Alim Marvasti, László RovóAbstract:The treatment of upper airway stenosis is considered to be one of the most difficult fields in laryngology. In the 100-year-old history of airway stenosis surgery several important works of Hungarian authors (Rethi, Lichtenberger, Pytel) are found. At the Department of Oto-Rhino- Laryngology and Head- Neck Surgery, University of Szeged our workgroup has been working on the treatment of upper airway stenosis for more than 30 years. Hereby we introduce our surgical concept for bilateral vocal fold paralysis, the minimally invasive endoscopic arytenoid abduction lateropexy (EAAL), which provides an immediate adequate airway with acceptable voice quality, and good swallow function. A new Endolaryngeal Thread Guide instrument (ETGI) is also presented here, which is essential for a safe, accurate, and fast suture loop creation around the arytenoid cartilage for this surgical procedure.

Endoscopic arytenoid abduction lateropexy for the treatment of neonatal bilateral vocal cord paralysis - Long-term results.
International Journal of Pediatric Otorhinolaryngology, 2019Co-Authors: Balazs Sztano, Ádám Bach, Vera Matievics, Eszter Erdelyi, Ilona Szegesdi, Christopher T. Wootten, László RovóAbstract:Abstract Objectives Bilateral vocal cord paralysis often causes severe dyspnea requiring an early airway intervention in neonates. Endoscopic arytenoid abduction lateropexy (EAAL) with suture is a quick, reversible, minimally-invasive vocal cord lateralizing technique to enlarge the glottis. The arytenoid cartilage is directly lateralized to a normal abducted position. It can be performed even in early childhood with the recently-introduced pediatric endoscopic Thread Guide instrument. The long-term results and the stability of the lateralization were evaluated. Methods Three newborns had inspiratory stridor immediately after birth. Laryngo-tracheoscopy revealed bilateral vocal cord paralysis. Unilateral, left-sided endoscopic arytenoid abduction lateropexy was performed with supraglottic jet ventilation. The follow-up period was >3 years. Results After extubation on the 4–7th postoperative day no dyspnea or swallowing disorder occurred. Laryngo-tracheoscopy, clinical growth charts and voice analysis showed satisfactory functional results. Conclusions The endoscopic arytenoid abduction lateropexy might be a favorable solution for neonatal bilateral vocal cord paralysis. In one step, airway patency can be achieved without irreversible damage to the glottic structures. Normal swallowing function was preserved. The results are durable, and neither medialization nor dyspnea re-appeared during observation.

a new solution for neonatal bilateral vocal cord paralysis endoscopic arytenoid abduction lateropexy
Laryngoscope, 2017Co-Authors: Shahram Madani, Ádám Bach, Balazs Sztano, Vera Matievics, Eszter Erdelyi, Ilona Szegesdi, Paul F Castellanos, László RovóAbstract:Objectives/Hypothesis Bilateral vocal cord paralysis in early childhood is a life-threatening condition, which often requires immediate intervention. One of the treatment options is a quick, reversible simple suture vocal cord lateralizing technique, whereby the arytenoid cartilage is directly lateralized to the normal abducted position. Considering pediatric laryngeal anatomy, a small endolaryngeal Thread Guide instrument was designed for precise suture insertion. Study Design New instrument validation. Methods Four newborns had inspiratory stridor immediately after birth; two had to be intubated. Laryngotracheoscopy revealed bilateral vocal cord paralysis. Unilateral, left-sided endoscopic arytenoid abduction lateropexy was performed with supraglottic jet ventilation on the 4th, 5th, 5th, and 27th day of life for the four patients, respectively. Results All babies remained intubated for 3 to 7 days with an uncuffed tracheal tube. After extubation, no dyspnea or swallowing disorder occurred. A subjective quality of life questionnaire, laryngotracheoscopy, clinical growth charts, and voice analysis showed satisfactory functional results. Conclusions Minimally invasive, quick, reversible endoscopic arytenoid abduction lateropexy might be a more favorable solution for neonatal bilateral vocal cord paralysis than earlier treatment strategies. In one step, the airway can be maintained without the risk of any permanent damage to voice production. Good swallowing function is also preserved. The specially modified endolaryngeal Thread Guide instrument gives a fast and effective option for creating the lateralized arytenoid position even in the technically challenging surgical context of a neonate larynx.

a new Thread Guide instrument for endoscopic arytenoid lateropexy
Laryngoscope, 2010Co-Authors: László Rovó, Shahram Madani, Balazs Sztano, Valeria Majoros, Gyoergy Smehak, Laszlo Szakacs, Jozsef JoriAbstract:Objectives/Hypothesis: The varied etiology of bilateral vocal cord immobility (BVCI) requires a wide range of surgical approaches. A new endolaryngeal Thread Guide instrument (ETGI) is presented here for a minimally invasive endoscopic lateropexy of the arytenoid cartilage, which might serve as a basis for a simple solution for the main types of BVCI. Study Design: Prospective study of BVCI patients who underwent surgery, including 22 bilateral vocal cord paralyses (BVCP), 12 mechanical fixations (MF), 10 posterior glottic stenoses, and two rheumatoid ankyloses. Methods: The ETGI is based on a built-in movable curved blade with a hole at its tip to Guide a Thread in and out again between the skin and the laryngeal cavity. The loops formed around the arytenoid cartilage cause abduction. In cases of fixations, the cricoarytenoid joints were properly mobilized as a first step with a combination of cold technique and CO2 laser. Results: As spirometric tests proved, 32 patients achieved improved breathing ability. One temporary tracheostomy was necessary and one patient with ongoing radiotherapy could not be decannulated. Subjectively, twelve patients' voices improved or approximated normal quality due to complete vocal cord recoveries on at least one side after lateropexy was ceased. Incomplete recovery with more or less impaired voice was observed in 16 cases. Three MF patients and two BVCP patients with poor overall health condition had severe dysphonia. Conclusions: Combined with simple and readily available methods, endoscopic arytenoid lateropexy is an effective solution for BVCIs with various etiologies. The ETGI facilitates this procedure with rapid and safe creation of fixating loops at the proper position. Laryngoscope, 2010
