RESUMEN
Dysphagia is a disease resulting from preparatory or transport disorder of the swallowing process and it is divided into oropharyngeal and esophageal phases according to the site of the lesion. The ear, nose and throat assessment focuses on the oropharyngeal phase, but differential diagnosis, investigation, and treatment of the cause of dysphagia is often a complex task requiring multidisciplinary approach and collaboration. The method of fiberoptic endoscopic evaluation of swallowing (FEES) has been introduced at the Department of Ear, Nose and Throat and Head-Neck Surgery, University of Szeged, enabling the examination of otorhinolaryngological and neurological disorders of swallowing as well as objective analysis of patients' swallowing quality. The fiberoptic endoscopic evaluation of swallowing is a minimally invasive procedure that allows visualization of the oropharyngeal phase of swallowing. It can identify anatomical abnormalities or neurological disorders causing dysphagia, thus playing a significant role in later patient rehabilitation. We hereby present our experiences in examinations of patients who underwent partial laryngectomy and/or pharyngectomy due to head and neck tumors as well as of those who underwent airway surgery duo to upper airway stenosis. Thanks to our collaboration with the Neurology Department, we also share our experiences gained during the examinations of patients struggling with oropharyngeal swallowing problems of various neurological origins.

Objectives: Glottic tumors with infiltration of the anterior/posterior commissure, and lesions with subglottic, cricoid, or cricoarytenoid joint infiltration have been highly controversial in the past, from the perspective of oncological safety. Although conservation laryngeal resection options exist, most are limited by the extent of resection proscribed by the technique and the postoperative functional results. Oncologically speaking, extended vertical hemilaryngectomy is often the optimal solution. However, limited reconstruction methods often compel total laryngectomy. Methods: Eight patients with vocal fold malignancy, which infiltrated the anterior and sometimes the posterior commissure and with subglottic extension and resultant uni/bilateral vocal fold motion impairment, were treated by single stage extended vertical partial laryngectomy with rotational crico-thyrotracheopexy as a functional reconstruction of the laryngeal framework. Patients were evaluated with objective and subjective function tests. Results: Histologic examination demonstrated tumor-free margins in every case. Definitive decannulation was successful in all cases within 2 weeks. All patients had a stable and adequate airway during follow-up and reported socially acceptable voice. Oral feeding was possible in seven patients. Conclusion: Rotational crico-thyrotracheopexy, as a single stage reconstruction technique, is based on well-vascularized, readily available, appropriately shaped local tissues, without significant donor site morbidity or need for long-term stenting to reconstruct large laryngeal defects after extended vertical hemilaryngectomy for advanced unilateral glottic tumors and is applicable even with supra/subglottic invasion or infiltration of the contralateral vocal fold. An adequate airway can be achieved with socially acceptable voice and safe swallowing without compromising oncologic reliability. Level of Evidence: 4 (retrospective case series review).
RESUMEN
Radiotherapy-induced heterotopic tissue calcification is an exceedingly rare complication in the head and neck region. We report a patient with extensive, radiotherapy-induced, combined subcutaneous and intramuscular, heterotopic calcification of the neck. An 80-year-old male presented with a 2-month history of severe dysphagia and a painful ulcer on the neck 42 years after salvage total laryngectomy following radiotherapy (total dose: 80 Gy) for a T3N0M0 glottic squamous cell carcinoma. We excluded recurrence or secondary malignancy by biopsy and performed computed tomography, which revealed subcutaneous and intramuscular calcification in the area of the skin ulcer and close to the hypopharyngeal wall, moreover, total occlusion of the common carotid and vertebral arteries bilaterally. Surgical correction involved removing the calcified lesions and closure using fasciocutaneous flap transposition. The patient has been asymptomatic for the past 48 months. Radiotherapy plays an essential role in the treatment of patients with head and neck squamous cell carcinoma. Distorted postoperative anatomy, excessive scar formation, radiotherapy-induced fibrosis as well as skin and subcutaneous tissue calcification can present as atypical findings.

OBJECTIVES: Slide laryngotracheoplasty is an effective, single-step procedure without tracheostomy and stenting for treating high-grade congenital subglottic stenosis in neonates and infants. Long-term outcomes were evaluated to assess the reliability of the procedure performed in this age of rapid development of the laryngeal structures. METHODS: We report five children who underwent slide laryngotracheoplasty before the age of 4 months, each with >3 years follow-up. Increases of length and bodyweight were systematically assessed. Breathing, swallowing, voice, and overall satisfaction was assessed by a quality of life questionnaire. Voice quality was objectively evaluated by measuring shimmer, jitter, fundamental frequency, and the harmonics-to-noise ratio. RESULTS: All patients had a stable and adequate airway during follow-up without any additional open airway surgery. The patients' voices were physiological, and the intervention had no negative impact on speech development. Swallowing function was optimally retained, and the patients' bodyweight gain and length were satisfactory. During at least 3 years of observation, the anastomosis remained stable and grew dynamically with the patient. CONCLUSIONS: Slide laryngotracheoplasty (as a single-step procedure) provides an adequate airway without tracheostomy, grafting, or stenting with good long-term functional results in selected neonates and infants with congenital subglottic stenosis.

In cases of transoral laryngeal and hypopharyngeal surgeries, the exploration of these relatively narrow anatomical regions is paramount. The conventional operational endoscopes allow the visualization of the surgical field, but - due to their structure - are not optimal regarding the coordination and simultaneous moving of microsurgical instruments. Furthermore, the relatively great distance between the surgical microscope and the endoscope has a negative impact on the illumination of the surgical area and the physical characteristics of the laser beam. The authors introduce a modified laryngoscope used in the field of laryngeal and hypopharyngeal surgery. The openings in the sides of the endoscope allow the lateral insertion of microsurgical devices, while the distance between the microscope and the target area can be significantly reduced. The endoscope is presented in addition to a tongue base and a glottic surgery. The introduced operational endoscope allows optimal exploration of the area of interest, the free and simultaneous moving of the microsurgical instruments, and the optimal usage of the laser beam.
RESUMEN
PURPOSE: Since the introduction of transcutaneous-transcricoidal needle approaches, electromyography (EMG) of the posterior cricoarytenoid muscle (PCA) became easier to perform and teach. Among the Neurolaryngology working group of the European Laryngological Society, several centers have adopted PCA EMG as part of their routine EMG workup in vocal fold immobility collectively gathering long-term experience. The purpose is to give an update and an extension to already existing guidelines on laryngeal EMG with specific regard to PCA EMG. METHODS: Consensus of all co-authors is based on continuous exchange of ideas and on joint laryngeal EMG workshop experiences over at least 7 years. A Delphi method of consensus development was used, i.e., the manuscript was circulated among the co-authors until full agreement was achieved. RESULTS: Step-by-step instructions on how to perform and interpret PCA EMG are provided. CONCLUSIONS: Further research should include the establishment of normal values for PCA and thyroarytenoid muscle (TA) EMG as well as studies on the nature of some unusual activation pattern commonly seen in chronically lesioned PCA.

PURPOSE: Endoscopic arytenoid abduction lateropexy (EAAL) is a reliable surgical solution for the minimally invasive treatment of bilateral vocal fold palsy (BVFP), providing a stable airway by the lateralization of the arytenoid cartilages with a simple suture. The nondestructive manner of the intervention theoretically leads to higher regeneration potential, thus better voice quality. The study aimed to investigate the respiratory and phonatory outcomes of this treatment concept. METHODS: 61 BVFP patients with significant dyspnea associated with thyroid/parathyroid surgery were treated by unilateral EAAL. Jitter, Shimmer, Harmonics to Noise Ratio, Maximum Phonation Time, Fundamental frequency, Voice Handicap Index, Dysphonia Severity Index, Friedrich's Dysphonia Index, Global-Roughness-Breathiness scale, Quality of Life, and Peak Inspiratory Flow were evaluated 18 months after EAAL. RESULTS: All patients had a stable and adequate airway during the follow-up. Ten patients (16.4%) experienced complete bilateral motion recovery with objective acoustic parameters in the physiological ranges. Most functional results of the 13 patients (21.3%) with unilateral recovery also reached the normal values. Fifteen patients (24.6%) had unilateral adduction recovery only, with slightly impaired voice quality. Eleven patients (18.0%) had false vocal fold phonation with socially acceptable voice. In 12 patients (19.7%) no significant motion recovery was detected on the glottic level. CONCLUSION: EAAL does not interfere with the potential regeneration process and meets the most important phoniatric requirements while guaranteeing the reversibility of the procedure-therefore serving patients with transient palsy. Further, a socially acceptable voice quality and an adequate airway are ensured even in cases of permanent bilateral vocal fold paralysis.

Összefoglaló. A veleszületett légúti szukületek gyakran kombináltan jelentkeznek, és más szervrendszert is érinto kísérobetegségekkel, illetve malformációkkal is társulhatnak. Figyelembe véve ezeket a tényezoket, illetve a csecsemokori légút speciális anatómiáját és sérülékeny szöveteit, a felso légúti szukületek sebészi kezelése újszülött- és csecsemokorban igen nagy kihívást jelento feladat, melynek célja a mihamarabbi definitív, stabil légút biztosítása a hangképzés és a nyelési funkció megorzésével. A laryngomalacia, a hangszalagbénulás és a subglotticus stenosis együttesen a gége veleszületett rendellenességeinek megközelítoleg 90%-áért felelos. A szerzok erre a három kórképre fókuszálva egy-egy eset kapcsán bemutatják a Szegedi Tudományegyetem Fül-Orr-Gégészeti és Fej-Nyaksebészeti Klinikáján muködo légútsebészeti munkacsoport által rutinszeruen alkalmazott innovatív sebészi módszereket. A bemutatott sebészeti megoldások egy lépésben, tracheostoma, sztentelés és graft beültetése nélkül azonnali stabil légutat biztosítanak jó hangminoséggel és nyelési funkcióval a supraglottis, a glottis és a subglottis dinamikus és statikus szukületei 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.

INTRODUCTION: Immunoglobulin G4-related disease (IgG4-RD) is a systemic fibro-inflammatory disorder. Laryngotracheal manifestation is very rare; therefore, it is usually associated with complex diagnostic and therapeutic problems. CASE REPORT: Herein, we report the case of a 35-year-old woman with idiopathic subglottic stenosis (ISGS) treated with one-step laryngotracheal reconstruction surgery. Postoperatively, the lesion was found to be a part of the IgG4-RD spectrum. Objective and subjective phoniatric tests, spirometry, and Quality of Life Questionnaire were used for the evaluation of postoperative functional results. Slide laryngotracheoplasty as a one-step surgery without stenting and tracheostomy ensured a sufficiently wide subglottic space with no adverse effect on voice quality. During a follow-up period of 22 months, endoscopy and computed tomography scan revealed no significant restenosis. The patient was able to return to premorbid activities of daily living without any further medical treatment. CONCLUSION: The laryngeal involvement of IgG4-RD is uncommon; however, it is a manifestation that should be included in the differential diagnosis of subglottic stenoses (SGS). Furthermore, subglottic IgG4-RD might be a potential etiological factor of ISGS and acquired airway stenosis after short-term intubation. Slide laryngotracheoplasty might be a favorable solution without stenting and tracheostomy even in special cases of SGS.
RESUMEN
OBJECTIVES/HYPOTHESIS: Arytenoid adduction (AA) has been indicated for unilateral vocal fold paralysis (UVFP) patients with vertical vocal fold height mismatch and/or large posterior glottic gaps that are unable to be adequately addressed by anterior medialization techniques. Although AA offers several advantages over other methods, it is technically challenging and involves significant laryngeal manipulation of the cricoarytenoid joint. A novel, minimally invasive endoscopic arytenoid medialization technique is presented for the closure of the posterior commissure. STUDY DESIGN: Prospective case series. METHODS: Seventeen consecutive patients were diagnosed and treated with unilateral endoscopic arytenoid medialization (EAM) combined with injection laryngoplasty because of unilateral vocal fold paralysis. Jitter, shimmer, harmonics-to-noise ratio (HNR), maximum phonation time (MPT), fundamental frequency (F0 ), Voice Handicap Index (VHI), peak inspiratory flow (PIF), and quality of life (QoL) were evaluated preoperatively, 1 month, and 1 year after EAM. RESULTS: Jitter, shimmer, HNR, and MPT significantly improved and remained stable 1 year after the intervention. F0 and PIF remained unchanged. Significant improvements in VHI and QoL demonstrated patient satisfaction with voicing and respiratory functions. CONCLUSIONS: Endoscopic arytenoid medialization is a quick, minimally invasive solution for unilateral vocal fold paralysis. With simultaneous augmentation of the vocal fold, it provides a complete glottic closure along the entire vocal fold in UVFP patients. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E903-E910, 2021.

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.

Microscope-assisted direct endoscopy of the airways and the upper gastrointestinal tract in general anesthesia is an essential diagnostic and therapeutic method of otorhinolaryngology. The quality of surgical exploration is a key for the good visibility and maneuverability of microsurgical tools. Beside the most commonly used Kleinsasser laryngoscope, the distending Weerda laryngoscope is a more favorable option for the exploration of the retrocricoid region. Narrow anatomical situation, examination and manipulation of lesions involving several sub-regions of the hypopharynx or larynx may be problematic in some cases even with this endoscope. The authors present the application of modified Weerda laryngoscopes with asymmetric spatula length in addition with four cases. The retrocricoid region, the distal part of the posterior hypopharyngeal wall and the proximal part of the esophagus can be easily visualized with this device. The modifications allow the introduction of new surgical techniques by increasing the number of applied microsurgical devices and their maneuverability. Orv Hetil. 2019; 160(7): 264-269.

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.

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. STUDY DESIGN: Case series. METHODS: Ten out of 21 BVCP patients who were treated with EAAL showed signs of isolated adduction recovery at 1 year and were chosen for this study. Functional results (objective and subjective voice analysis, spirometric measurement) and vocal cord movements were assessed preoperatively, 1 week and 1 year after EAAL. Laryngeal electromyography was performed on the 12th postoperative month. RESULTS: The volitional adductor movement seen on laryngoscopy was corroborated by laryngeal electromyography evaluation. Peak inspiratory flow increased significantly after EAAL. Quality-of-life scores also showed high patient satisfaction. Shimmer showed consistent improvement along with harmonic-to-noise ratio and average maximal phonation time in parallel with the improving vocal cord movement. Complex voice analysis and subjective self-evaluation tests also demonstrated significant improvement. CONCLUSIONS: EAAL, as a minimally invasive, nondestructive airway widening technique, does not interfere with the potential regeneration process that can still occur after BVCP, allowing for laryngeal functional recovery. It is a safe and effective treatment for BVCP that allows a simple solution with good phonatory, swallowing, and respiratory benefits by unilateral passive and reversible vocal cord lateralization.

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. AIM: Endoscopic arytenoid abduction lateropexy is an accepted reversible, minimally invasive technique that provides an immediate patent airway by the lateralisation of the arytenoid cartilage with a suture. The aim of our study was to analyze the phonatory and respiratory outcomes of this treatment concept. METHOD: Two patients suffering from bilateral vocal cord palsy were treated with endoscopic arytenoid abduction lateropexy. After recovery of the vocal cord movements, the sutures were removed. Spirometric and phoniatric results of the two patients were analysed after suture removal. RESULTS: Good spirometric parameters and normal voice quality were detected in both cases. CONCLUSIONS: These results prove the high reversibility of the minimally invasive endoscopic arytenoid abduction lateropexy. Lateralization suture can be removed in the case of vocal cord movement recovery, and phonation may be physiological. Orv Hetil. 2018; 159(29): 1188-1192.

In addition to traditional risk factors such as smoking, alcohol consumption and betel nut use, human papillomavirus (HPV) infection also plays a role in the development of head and neck squamous cell carcinomas (HNSCCs). Although among European countries the highest incidence and mortality rates of head and neck cancer types were recorded in Hungary, data regarding HPV prevalence in HNSCCs is scarce. We collected biopsy and saliva samples from patients diagnosed with HNSCC or oral potentially malignant disorders (OPMDs) and tested them for the presence of HPV using the PCR consensus primer set MY09/11 and the GP5+/6+ primer pair. HPV genotypes were assessed by sequencing of the amplified PCR fragments. Oral mucosa and saliva samples from tumor- and OPMD-free individuals were also analysed. HPV was detected in 11 out of 60 HNSCC samples (18%). All of the HPV positive tumors carried HPV type 16. 5 out of the 57 saliva samples collected from HNSCC patients was HPV positive (8.8%); among them, in addition to HPV16, HPV13 was also detected. Tumors located to the oropharynx had the highest HPV positivity rate with 50% (7 out of 14), which was significantly higher than the HPV prevalence in oral mucosa samples collected from controls (0 out of 20; pâ¯>â¯0.001) or in OPMD biopsies (0 out of 21, pâ¯>â¯0.001). 2 out of 57 control saliva samples (3.5%, subtype HPV13 and 11) and 3 out of 39 saliva samples from OPMD patients (7.7%, subtype HPV18, 81 and 10) were HPV positive. Our data suggested that HPV16 infection may contribute, in concert with cigarette smoking, to the development of a subset of head and neck cancers in Hungary. HPV16 infection per se does not account, however, for the high HNSCC incidence rate recorded in this country.

The development of the therapeutic possibilities of vocal cord immobility necessitated the parallel renewal of diagnostic methods. In the last years, laryngeal electromyography, which was first introduced more than 70 years ago, has been re-discovered. After reviewing the international literature and their own experience, the authors present the indications, technical requirements, method and, particularly, the evaluation of the results of this procedure. Laryngeal electromyography makes the differentiation between mechanical fixation and immobility with neurological origin of the vocal folds possible. In case of laryngeal paralysis/paresis it also evaluates objectively the severity of neural injury, the prognosis of the disease and the necessity of any glottis-widening procedure. The widespread application of dynamic rehabilitation interventions is not conceivable without the routine application of laryngeal electromyography, so this sensitive diagnostic tool has to be introduced in all laryngological centers.

In unilateral vocal cord paralysis (UVCP), hoarseness is usually the leading symptom; however, the diminished airway might lead to breathing problems as well, especially with exertion. The application of the classic resection glottis enlarging or medialization procedures might shift the breathing and/or the voice to a worse condition. The non-destructive endoscopic arytenoid abduction lateropexy (EAAL) might be a solution for this problem. The aim of our study was to analyze the phonatory and respiratory outcomes of this treatment concept. The first year phoniatric [Jitter, Shimmer, harmonics-to-noise ratio (HNR), maximum phonation time (MPT), fundamental frequency (F 0), Voice Handicap Index (VHI), Dysphonia Severity Index (DSI), Global-Roughness-Breathiness scale (GRB)], peak inspiratory flow (PIF), and quality of life (QoL) were evaluated in ten UVCP patients treated by EAAL for dyspnea generally presented on exertion. PIF, Jitter, QoL, GRB, and VHI significantly improved. DSI, HNR, and MPT got non-significantly better. F 0 slightly increased in all patients, a mild deterioration of shimmer was observed. These results prove that improving respiratory function is not necessarily associated with a deterioration in voice quality. The EAAL provides a significant improvement in breathing and the vibratory parameters of the postoperative, more tensed and straightened vocal cords proved to be more advantageous than the original (para) median 'loose' position. The over-adduction of the contralateral side more or less compensates for the disadvantageous, more lateral position of the operated side. EAAL might be an alternative treatment for unilateral vocal cord paralysis associated with breathing problems.

OBJECTIVES: The complex laryngeal functions are fundamentally defined by the cricoid cartilage. Thus, lesions requiring subtotal or total resection of the cricoid cartilage commonly warrant total laryngectomy. However, from an oncological perspective, the resection of the cricoid cartilage would be an optimal solution in these cases. The poor functional results of the few reported cases of total and subtotal cricoidectomy with different reconstruction techniques confirm the need for new approaches to reconstruct the infrastructure of the larynx post cricoidectomy. STUDY DESIGN: Retrospective case series review. METHODS: Four consecutive patients with low-grade chondrosarcoma were treated by cricoidectomy with rotational thyrotracheopexy reconstruction to enable the functional creation of a complete cartilaginous ring that can substitute the functions of the cricoid cartilage. The glottic structures were stabilized with endoscopic arytenoid abduction lateropexy. Patients were evaluated with objective and subjective function tests. RESULTS: Tumor-free margins were proven; patients were successfully decannulated within 3 weeks. Voice outcomes were adequate for social conversation in all cases. Oral feeding was possible in three patients. CONCLUSION: Total and subtotal cricoidectomy can be a surgical option to avoid total laryngectomy in cases of large chondrosarcomas destroying the cricoid cartilage. The thyrotracheopexy rotational advancement technique enables the effective reconstruction of the structural deficit of the resected cricoid cartilage in cases of total and subtotal cricoidectomy. An adequate airway for breathing, swallowing, and voice production can be reconstructed with good oncological control. In cases where the pharynx is not involved, good swallowing function can also be achieved. LEVEL OF EVIDENCE: 4. Laryngoscope, 127:1109-1115, 2017.

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.
