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. Laryngotracheoscopy 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 4-7 th 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.
Objectives Subglottic stenosis is the most common laryngeal anomaly necessitating tracheostomy in early childhood. Crico‐ and laryngotracheal resection and laryngotracheal reconstruction—usually with autologous cartilage graft implantation—are the most effective treatments. These surgical techniques are obviously challenging in neonatal age and infancy. However, a reconstructive surgery performed at early age may prevent the sequel of complications. Methods The authors present their novel surgical method for congenital subglottic stenosis. Seven infants had inspiratory stridor; two of them had to be intubated and one required tracheostomy. Laryngotracheoscopy, CT or MRI revealed subglottic stenosis: Cotton‐Myer grade II in one, and grade III in six cases. Slide laryngotracheoplasty was performed before 5 months of age (10–130 days), with a follow‐up period of average 36 months (4–80 months). Phoniatry and quality of life questionnaire were used for evaluation of postoperative results. Results Slide laryngotracheoplasty in the neonatal age made the temporary tracheostomy unnecessary. All babies remained intubated for 3 to 10 days with an uncuffed tracheal tube. After extubation, no dyspnea or swallowing disorder occurred. A subjective quality of life questionnaire, laryngotracheoscopy, clinical growth charts showed satisfactory functional results. Conclusions Single‐stage slide laryngotracheoplasty might be a favorable solution for subglottic stenosis, even in early childhood. In one step, the airway can be maintained without stenting and tracheostomy. Level of Evidence 4 Laryngoscope, 130:E199–E205, 2020
Összefoglaló. A veleszületett légúti szűkületek gyakran kombináltan jelentkeznek, és más szervrendszert is érintő kísérőbetegségekkel, illetve malformációkkal is társulhatnak. Figyelembe véve ezeket a tényezőket, illetve a csecsemőkori légút speciális anatómiáját és sérülékeny szöveteit, a felső légúti szűkületek sebészi kezelése újszülött- és csecsemőkorban igen nagy kihívást jelentő feladat, melynek célja a mihamarabbi definitív, stabil légút biztosítása a hangképzés és a nyelési funkció megőrzésével. A laryngomalacia, a hangszalagbénulás és a subglotticus stenosis együttesen a gége veleszületett rendellenességeinek megközelítőleg 90%-áért felelős. A szerzők erre a három kórképre fókuszálva egy-egy eset kapcsán bemutatják a Szegedi Tudományegyetem Fül-Orr-Gégészeti és Fej-Nyaksebészeti Klinikáján működő légútsebészeti munkacsoport által rutinszerűen alkalmazott innovatív sebészi módszereket. A bemutatott sebészeti megoldások egy lépésben, tracheostoma, sztentelés és graft beültetése nélkül azonnali stabil légutat biztosítanak jó hangminőséggel és nyelési funkcióval a supraglottis, a glottis és a subglottis dinamikus és statikus szűkületei esetén egyaránt. Orv Hetil. 2021; 162(52): 2100–2106. Summary. Congenital airway stenoses occur frequently in combinations or may be associated with comorbidities and malformations affecting other organ systems. Considering these factors as well as the special anatomy and vulnerable tissues of the pediatric airway, surgical treatment in neonates and infants is an extremely challenging task. The ultimate goal of the management is to ensure a definitive and adequate airway as soon as possible with the preservation of voice and swallowing. Laryngomalacia, vocal cord palsy and subglottic stenosis together account for approximately 90% of congenital laryngeal disorders. Focusing on these three diseases, the authors – the airway surgery working group at the Department of Otolaryngology and Head and Neck Surgery, University of Szeged, Hungary – present their routinely applied innovative surgical strategies in connection with three cases. The presented ‘one-step’ surgical solutions provide immediate stable airway with good voice quality and swallowing function without tracheostomy, stenting, or graft implantation for both dynamic and static stenoses of the supraglottis, glottis, and subglottis.
