RESUMO
OBJECTIVES: Airway reconstruction for laryngo tracheal stenosis (LTS) improves dyspnoea. There is little evidence relating to impact upon voice and swallowing. We explored voice and swallowing outcomes in adults with LTS before and after reconstructive surgery. DESIGN: Outcome measures were collected pre-reconstructive surgery, two-weeks post-surgery and up to 4-6 months post-surgery. SETTING: Tertiary referral centre. PARTICIPANTS: With ethical approval, twenty consecutive adult (≥18 years) LTS patients undergoing airway reconstruction were prospectively recruited. MAIN OUTCOME MEASURES: These included physiological values (maximum phonation time (MPT) and fundamental frequency; penetration aspiration score, residue score), clinician-reported (GRBAS, functional oral intake score, 100ml Water Swallow Test) and patient-reported outcomes (Voice Handicap Index-10, Reflux Symptoms Index, Eating Assessment Tool, Dysphagia Handicap Index). RESULTS: The observational study identified patient-reported and clinician-reported voice and swallow difficulties pre- and post-surgery; median and interquartile range are reported at each time point: Voice Handicap Index-10 23 (8-31); 20.5 (9-33.5), 24.5 (12.5-29); Dysphagia Handicap Index 9 (0-37); 13 (7-44); 15 (4-34); GRBAS grade 1(1-2); 2 (1-2.5); 2(1-2); 100ml Water Swallow Test volume score 16.7 (11.1-20); 14.3 (12.5-16.7); 16.7 (14.3-20.0); 100ml Water Swallow Test capacity score 16.3 ± 9.0; 11.0 ± 4.1; 12.5 ± 2.6. CONCLUSIONS: We present the first prospective data on voice and swallowing outcomes in adults with LTS before and after reconstructive surgery. The variability of the outcomes was higher than expected but importantly, for many the voice and swallow outcomes were not within normal limits before surgery. The clinical value of the study demonstrates the need for individual assessment and management of LTS patients' voice and swallowing.

PURPOSE: To evaluate the feasibility and clarify the appropriate indications for extubation immediately after single-stage laryngotracheal reconstruction (SS-LTR) in pediatric subglottic stenosis (SGS). METHODS: A retrospective study was performed from July 2017 to July 2022. All patients underwent SS-LTR with anterior costal cartilage graft. Information such as demographics, comorbidities, history of intubation or tracheostomy, Classification and grading of airway stenosis, the operation-specific decannulation rate and overall decannulation rate were analyzed. RESULTS: Twenty-two patients with simple SGS were identified. The median age at SS-LTR was 19 months (IQR = 18.5 months). Fourteen patients (63.6%) were intubated prior to the presentation of symptoms. Fourteen patients (63.6%) required preoperative tracheostomy to maintain a secure airway. Eight patients (36.4%) had congenital SGS, 10 patients (45.5%) had acquired SGS, and 4 patients (18.2%) had mixed SGS. Three patients had Grade II stenosis. Nineteen patients had Grade III stenosis. Comorbidities were found in 10 patients (45.5%). Major comorbidities were pneumonia. Congenital airway anomalies were found in 6 patients (27.3%). After anesthesia, all 22 patients were successfully extubated and returned to the general ward. Twenty patients had a satisfactory airway after SS-LTR. Two patients required reintubation or tracheostomy after operation. Operation-specific decannulation rate was 90.9%. The overall decannulation rate is 100%. CONCLUSION: SS-LTR with anterior costal cartilage graft is an effective method to treat simple SGS ranging from Grades I to III in children. Extubation immediately after surgery is safe and feasible.

OBJECTIVE: To present treatment outcomes in elderly and senile patients with cicatricial tracheal stenosis (CTS) and features of their perioperative management. MATERIAL AND METHODS: The study included 46 elderly and senile patients with CTS. We analyzed their gender and age, body mass index, etiology, extent and degree of stenosis, comorbidity index and ASA grade, postoperative complications according to TMM grading system. RESULTS: Age of patients varied from 61 to 95 years (mean 66.38±8.65). Post-intubation stenosis was detected in 7 (15.2%) patients, post-tracheostomy CTS - in 39 (84.8%) patients (2 (4.3%) ones with tracheoesophageal fistula and 18 (39.1%) ones with tracheomalacia). CTS length ranged from 8 to 65 mm. The causes of invasive mechanical ventilation were traumatic brain and spinal trauma in 6 cases, emergency surgery in 11 cases and therapeutic diseases in 29 cases. CTS of cervical trachea was found in 21 patients, subglottic larynx and cervical trachea - 8 patients, cervical and upper thoracic trachea - 12 patients, thoracic segment - 3 patients, multifocal lesions - 2 patients. The Charlson index ranged from 5 to 12 points. ASA grade II was observed in 8 (17.4%) patients, III - 28 (60.9%), IV - in other ones. Circular resection was performed in 5 patients, laryngotracheoplasty - in 37 patients. CTS repair and tracheoesophageal fistula closure with laryngotracheoplasty were carried out in 2 patients. Postoperative complications occurred in 18 (39.1%) patients, mortality was 2.17%. In 21.7% of cases, complications were associated with tracheal suture. Endoscopic procedures, cryosurgery and hyperbaric oxygenation were used for correction. Good and satisfactory treatment outcomes were achieved in 86.5% of patients. CONCLUSION: Surgical treatment of CTS in elderly and senile patients requires participation of interdisciplinary team with special experience. Laryngotracheoplasty is safe and effective in these patients, and indications for circular resection are still limited.

OBJECTIVE: To describe 10-year experience of treating the cicatricial tracheal stenosis (CTS) in a regional multi-field hospital. MATERIAL AND METHODS: There were 120 CTS patients aged 13-75 years. In 8 (6.7%) patients, CTS was combined with tracheoesophageal fistula (TPF). Post-intubation stenosis was diagnosed in 16 (13.3%) cases, post-tracheostomy - in 102 (85%) ones, post-traumatic - in 2 (1.7%) patients. CTS length ranged from 1.2 to 8 cm. Fifty (41.7%) patients had cervical CTS, 40 (33.3%) patients - cervico-thoracic tracheal stenosis, 11 (9.2%) patients - tracheal stenosis at the thoracic level. Nineteen (15.8%) patients had multifocal stenoses. We used endoscopic techniques, circular tracheal resection (CTR) and laryngotracheal reconstruction. RESULTS: Postoperative mortality rate was 0.83%. CTR was performed in 33 patients, laryngotracheal reconstruction - 77, endoscopic stenting - 6 patients. In 4 cases, local CTS was eliminated by bougienage and argon plasma exposure. CTS was successfully disconnected with TEF using CRT in 3 cases, laryngotracheoplasty and stenting - in 5 cases. The fenestrated tracheal defect was closed by a three-layer autologous flap in 59 patients. Of these, autologous flap was reinforced with porous nickel-titanium implants in 17 patients. Postoperative complications after CRT occurred in 6 (16.7%) patients (anastomotic leakage - 2, anastomositis - 1, restenosis - 2). No patients died. Postoperative complications after laryngotracheal reconstruction were observed in 18 (23.4%) patients including 5 ones with restenosis who underwent CTR with a favorable outcome. CONCLUSION: CTS treatment requires a multidisciplinary approach. Each surgery has certain indications and place in treatment algorithm. CTR is highly effective, but may be accompanied by complications associated with tracheal anastomosis. Decrease of postoperative morbidity will improve immediate and long-term results of CTS treatment. The chosen treatment algorithm ensured good and satisfactory results in 98% of patients.

The report presents a case of non-standard two-stage treatment of post-traumatic multifocal cicatricial tracheal stenosis with atresia of subglottic larynx, involvement of vocal cords, and 33-year cannulation. At the first stage, bougienage through a tracheostomy, endoscopic argon plasma exposure, circular tracheoglottic resection with tracheostomy and 3/4 circle anastomosis, formation of a laryngotracheostomy with endoprosthetics were applied simultaneously. The second step was to eliminate the extensive fenestrated tracheo-laryngeal defect using titanium nickelide reinforcing implants. The individual algorithm made it possible to successfully eliminate complex tracheo-laryngeal stenosis with long-term cannulation and demonstrate excellent long-term treatment results.

OBJECTIVES/HYPOTHESIS: This study was designed to evaluate the graft healing effect of topical application of platelet-rich plasma (PRP) for laryngotracheal reconstruction (LTR) in a rabbit model. STUDY DESIGN: It is a prospective randomized control animal study. MATERIALS AND METHODS: Sixteen healthy New Zealand White rabbits were assigned to two groups of eight animals each. The control group underwent LTR with anterior auricular cartilage graft. The PRP group underwent the same surgical procedure plus PRP application over the anastomosis and surgical field. Two animals in the PRP group and two animals in control group died due to severe respiratory distress on postoperative days 10, 12, 15, and 18. Six rabbits (n = 3 for control group and n = 3 for PRP group) were sacrificed at 4 weeks, and six rabbits (n = 3 for control group and n = 3 for PRP group) were sacrificed at 8 weeks. Laryngotracheal regions were evaluated histopathologically. RESULTS: Macroscopically, the average anteroposterior and lateral diameter of the reconstructed region and the degree of lumen patency on postoperative 4th week and 8th week were not statistically different among two groups. There was no significant difference between the groups in terms of any of the microscopic findings when the analysis was made separately. However, analysis of the total number of rabbits has shown that new cartilage formation and angiogenesis were more pronounced in PRP group than control group. CONCLUSIONS: Application of PRP contributed to better healing in airway surgery by promoting a release of growth factors that stimulate new cartilage formation and angiogenesis.

PURPOSE: The present study analyzed the clinical features and surgical outcomes of laryngotracheal reconstruction (LTR) in pediatric patients with severe acquired subglottic stenosis (SGS) based on the range of stenosis. The aim was to clarify the indications for LTR in severe acquired SGS. METHODS: The medical records of 33 pediatric patients with severe acquired SGS (Myer-Cotton grade III or IV) at our institution between January 1994 and December 2013 were retrospectively reviewed. RESULTS: Nine patients had stenosis localized at the subglottis (localized SGS), and twenty-four patients had stenosis extending to the glottis or supraglottis from the subglottis (extended SGS). 66.7 % (6/9) of localized SGS patients were intubated after infancy, and 95.8 % (22/23) of extended SGS patients were intubated in the neonatal period. The duration of intubation was significantly shorter with localized than with extended SGS. Sixteen patients underwent LTR. The operation-specific decannulation rate was 80.0 % (4/5) in the localized SGS group and 14.3 % (1/7) in the extended SGS group. CONCLUSION: The range of stenosis was affected by the period and duration of endotracheal intubation. Surgical outcomes of LTR tended to differ between localized SGS and extended SGS. LTR can be effective for localized SGS.

OBJECTIVES: Laryngotracheal reconstruction (LTR) procedures for repair of complex congenital or acquired airway stenosis of the larynx and/or trachea in pediatric patients have advanced over recent decades. The aim of the present project was to investigate the relationships among diagnoses, type of surgical intervention, and laryngeal findings in a post-LTR patient cohort to identify factors associated with adequate airway protection and swallowing outcomes. METHODS: A retrospective review of 30 airway patients undergoing simultaneous or close interval functional laryngeal and swallowing examinations was completed. Analyses of the data were performed to examine factors associated with postoperative airway protection and swallowing function. The patient cohort was separated into 2 groups according to the adequacy of their airway protection (aspiration and no aspiration) as judged by clinicians via instrumental examination. RESULTS: Data analyses revealed statistically significant differences between the 2 groups for 3 key parameters: laryngeal closure, laryngeal closure timeliness (relative to bolus flow), and overall swallowing coordination. CONCLUSIONS: These findings contribute to the knowledge of laryngeal closure patterns present in patients undergoing airway reconstruction and the effect on the essential laryngeal function of airway protection during swallowing. Implications of the data for swallowing function in this population are discussed.

OBJECTIVES: Laryngotracheal reconstruction (LTR) has revolutionized the management of pediatric subglottic stenosis (SGS). However, postoperative stenosis remains a difficult hurdle to overcome. Our goal is to determine the clinical impact of recalcitrant stenosis after LTR and the factors contributing to postoperative stenosis. STUDY DESIGN: Retrospective review of 181 open LTR patients between 2008 and 2021. SETTING: Stand-alone tertiary children's hospital. METHODS: Recalcitrant stenosis was defined as new or worsening stenosis despite open LTR. Fisher's exact and Mann-Whitney tests were used to detect differences in categorical and continuous clinical data between patients with and without treatment-resistant stenosis. Time-to-decannulation analysis of both groups was performed using Kaplan-Meier analysis and evaluated with log-rank and Cox proportional hazards regression. Multivariate logistical regression was used to assess the validity of associations found in univariate analysis. RESULTS: As expected, the 27 patients with postoperative stenosis were less likely to be decannulated (P < .001, Fisher's Exact), more likely to require a postoperative tracheostomy (P < .001, Fisher's Exact) or revision LTR (P < .001, Fisher's Exact) and had prolonged time to decannulation (P < .001, Log-rank). Children with Grade IV SGS (P = .004, Fisher's Exact), and those with longer suprastomal stent duration (P = .03, Fisher's Exact) were more likely to suffer from recalcitrant stenosis. Stent duration longer than 4 weeks (P = .01) contributed to refractory stenosis when controlling for all aforementioned variables using multivariable logistic regression. Interposition grafts had a protective effect (P = .005). CONCLUSION: Maintaining suprastomal stents over 4 weeks after LTR increases the risk for postoperative stenosis and its sequelae.

OBJECTIVES: To determine how initial postoperative airway endoscopy findings after stent removal predict successful decannulation in children undergoing double-staged laryngotracheoplasty (dsLTP). Secondary objectives assessed timing of decannulation and number of endoscopic interventions needed after dsLTP. METHODS: A case series with chart review included children who underwent dsLTP at a tertiary children's hospital between 2008 and 2021. Rates of decannulation, time to decannulation, and number of interventions after dsLTP were recorded for children with high- or low-grade stenosis at the first bronchoscopy after stent removal. RESULTS: Of the 65 children who were included, 88% had high-grade stenosis and 98% had a preoperative tracheostomy. Successful decannulation happened in 74% of the children, and 44% of the children were decannulated within 12 months of surgery. For children with low-grade stenosis at the first endoscopy after stent removal, 84% were successfully decannulated compared with 36% of the children with high-grade stenosis (p = 0.001). After dsLTP, children with high-grade stenosis required 7.5 interventions (SD: 3.3) compared with 4.0 interventions (SD: 3.0) for children with low-grade stenosis (p < 0.001). Decannulated children with high-grade stenosis necessitated more endoscopic procedures (7.0 vs. 3.7, p = 0.02). Time to decannulation was similar between children with high- and low-grade early postoperative stenosis (21.9 vs. 17.8 months, p = 0.63). CONCLUSIONS: Higher grade stenosis identified on the first airway endoscopy after suprastomal stent removal is correlated with lower decannulation rates and more postoperative endoscopic interventions. Although time to decannulation was not impacted by early stenosis grade, surgeons might utilize these early airway findings to counsel families and prognosticate possible surgical success.

This article introduces a new endoscopic technique for anterior laryngotracheal reconstruction (LTR) using costal rib cartilage grafting in a 2-year-old patient with acquired Grade III subglottic stenosis. The procedure involves an endoscopic incision in the cricoid cartilage's anterior midline and successful outcomes were achieved without complications. The study emphasizes the benefits of this approach, such as reduced hospital stays, shorter operation time, and decreased scarring, but acknowledges the necessity for further human trials to validate its effectiveness in treating different grades of laryngeotracheal stenosis.

RESUMO
OBJECTIVES: The primary objective is to describe a case in which a steroid-eluting implant was utilized to help prevent postoperative granulation and restenosis in a patient who underwent double-stage laryngotracheal reconstruction (dsLTR) for subglottic stenosis. METHODS: This case presents a 3-year-old female who underwent dsLTR with anterior cartilage graft placement and posterior sagittal split for subglottic stenosis. A silicone stent was placed at the time of the dsLTR. After stent removal, direct laryngoscopy and bronchoscopy (DLB) was performed at 4 to 5 week intervals. These visits revealed a significant amount of supraglottic and glottic edema, and granulation tissue at the proximal aspect of the graft contributing to airway obstruction and restenosis. This was treated twice with CO2 laser excision, balloon dilation, and triamcinolone injection. On the third treatment with these modalities, a mometasone furoate implant was inserted as an adjunctive therapy. The implant was inserted to lateralize the vocal folds, prevent webbing, and to extend to the narrowed area within the subglottis to prevent granulation and restenosis. These same treatments were repeated at the fourth visit with another mometasone furoate implant of a smaller size placed in the same location. RESULTS: Findings on DLB since treatment with the steroid-eluting implants have shown persistent granulation tissue limited to the tracheostomy stoma site. Treatments with CO2 laser, balloon dilation, and triamcinolone injection have continued, with occasional use of silver nitrate cautery at the external stoma site. There has not been any significant evidence of edema, granulation, or stenosis in the glottis or subglottis to require another steroid-eluting implant. CONCLUSIONS: Steroid-eluting implants appear to be a safe and effective adjunctive therapy in the routine surveillance of pediatric patients with a tracheostomy who have undergone dsLTR. They may help combat granulation formation and restenosis seen in some dsLTR patients.

OBJECTIVES: Surgical treatment for airway stenosis necessitates personalized techniques based on the stenosis location and length, leading to favourable surgical outcomes. However, there is limited literature on functional outcomes following laryngotracheal surgery with an adequate number of patients. METHODS: We conducted a retrospective analysis of patients who underwent laryngotracheal surgery at the Department of Thoracic Surgery, Medical University of Vienna, from January 2017 to June 2021. The study included standardized functional assessments before and after surgery, encompassing spirometry, voice measurements, swallowing evaluation and subjective patient perception. RESULTS: The study comprised 45 patients with an average age of 51.9 ± 15.9 years, of whom 89% were female, with idiopathic being the most common aetiology (67%). Procedures included standard cricotracheal resection in 11%, cricotracheal resection with dorsal mucosal flap in 49%, cricotracheal resection with dorsal mucosal flap and lateral cricoplasty in 24% and single-stage laryngotracheal reconstruction in 16%. There were no in-hospital mortalities or restenosis cases during the mean follow-up period of 20.8 ± 13.2 months. Swallowing function remained intact in all patients. Voice evaluations showed a decrease in fundamental vocal pitch [203 (81-290) Hz vs 150 (73-364) Hz, P < 0.001] and dynamic voice range (23.5 ± 5.8 semitones vs 17.8 ± 6.7 semitones, P < 0.001). However, no differences in voice volume were observed (60.0 ± 4.1 dB vs 60.2 ± 4.8 dB, P = 0.788). The overall predicted voice profile changed from R0B0H0 to R1B0H1. CONCLUSIONS: Laryngotracheal surgery proves effective in fully restoring breathing capacity while preserving vocal function. Even in cases of high-grade and complex airway stenosis necessitating laryngotracheal reconstruction, favourable functional outcomes can be achieved.

Background: Cricotracheal resection (CTR) is considered the standard of care for patients suffering from idiopathic subglottic stenosis (iSGS). Although CTR results in permanent restoration of airway patency, it has a mild to moderate impact on voice quality. Here we propose modifications of the standard CTR technique to make it a voice-preserving procedure. Methods: Five women with iSGS underwent voice-sparing CTR between January 2022 and January 2023. In this procedure, through several technical adaptations, the function of the cricothyroid joint was preserved. Outcomes of these voice-sparing CTRs were compared to outcomes in patients who underwent standard CTR in our institution. All patients underwent full functional preoperative and postoperative workups, including spirometry, voice measurements, patient self-assessment, and fiberoptic endoscopic evaluation of swallowing. Results: All 5 patients in the study group suffered from iSGS with high-grade Myer-Cotton III° stenosis (100%); 1 patient had previously undergone endoscopic laser resection. Voice evaluation demonstrated a nearly unchanged fundamental pitch (mean preoperative, 191 ± 73.1 Hz; postoperative, 182 ± 64.2 Hz) and dynamic voice range (preoperative, 24.4 semitones; postoperative, 20.4 semitones). This was in contrast to the control group, in which significantly reduced voice quality was observed. Conclusions: In selected patients suffering from iSGS, excellent functional results can be obtained with voice-sparing CTR.
RESUMO
Endoscopic technology has increased our options for treatment of airway stenosis in a minimally invasive manner. This novel technique advances endoscopic posterior graft placement by creation of an airway pocket, potentially reducing risk of graft migration and improving outcomes.

INTRODUCTION: There has been a notable increase in the number of neonates born 28 weeks gestational age or younger in the United States. Many of these patients require tracheostomy early in life and subsequent laryngotracheal reconstruction (LTR). Although extremely premature infants often undergo LTR, there is no known study to date examining their post-surgical outcomes. OBJECTIVES: To compare decannulation rates, time to decannulation and complication rates between LTR patients born extremely premature to those born preterm and term. METHODS: We identified 179 patients treated at a stand-alone tertiary children's hospital who underwent open airway reconstruction from 2008 to 2021. A Chi Squared test was used to detect differences in categorical clinical data between the groups of patients. A Mann-Whitney test was used to analyze continuous data within these same groups. Time to decannulation analysis was performed using Kaplan Meier analysis and evaluated with log-rank and Cox proportional hazards regression. RESULTS: Children born extremely premature were more likely to incur complications following LTR (OR = 2.363, p = 0.005, CI 1.295-4.247). There was no difference in time to decannulation (p = 0.0543, Log-rank) or rate of decannulation (OR = 0.4985, p = 0.05, CI 0.2511-1.008). Extremely premature infants were more likely to be treated with an anterior and posterior grafts (OR = 2.471, p = 0.004, CI 1.297-4.535) and/or an airway stent (OR = 3.112, p < 0.001, CI 1.539-5.987). CONCLUSION: Compared with all other patients, extremely premature infants have equivalent decannulation success, but are at an increased risk for complications following LTR.

Laryngotracheal stenosis is the common endpoint for any process that results in the narrowing of the airway at the level of the glottis, subglottis, or trachea. Although endoscopic procedures are effective in opening the airway lumen, open resection and reconstruction can be necessary to reconstitute a functional airway. When resection and anastomosis are insufficient due to extensive length or location of the stenosis, autologous grafts can be used to expand the airway. Future directions in airway reconstruction include tissue engineering and allotransplantation.

OBJECTIVES: Outcome measures of revision open airway surgery in pediatric laryngotracheal stenosis (LTS) are reported. METHODS: Data on 46 pediatric LTS patients undergoing revision open airway surgery were collected retrospectively. The measured outcomes were decannulation rate, time to decannulation, postoperative complications, additional surgery to achieve decannulation, and functional results. RESULTS: The most common revision surgery was partial cricotracheal resection (PCTR) in 21/46, followed by extended PCTR (ePCTR) in 20/46, and laryngotracheal reconstruction (LTR) in 5/46 patients. A 90.7% overall decannulation rate (ODR) and a 74.4% operation-specific decannulation rate (OSDR) were achieved. Delayed decannulation was identified in children aged 5 years or less (p = 0.038) and in patients with previous primary open airway surgery (p = 0.039). Complications were observed in 52.2% of patients. To achieve optimal airway patency, additional open or endoscopic airway surgeries were necessary in 30.4% and 47.7% of patients, respectively. Age 5 years or less (p = 0.034), multiple comorbidities (p = 0.044), revision ePCTR (p = 0.023), and laryngeal stenting (p = 0.018) were risk factors requiring additional open surgery to achieve age-appropriate airway. Failed primary open airway surgery (p = 0.034) and comorbidities (p = 0.044) were risk factors for a higher rate of additional endoscopic surgeries. Postoperatively 63.0% of patients achieved normal breathing, 82.2% were dysphonic and 91.1% were orally fed. CONCLUSIONS: In this report, the patient's age under 5 years, previous primary open airway surgery, medical comorbidities, and laryngeal stenting had a significant negative impact on revision open airway surgery outcomes.

OBJECTIVES: To review treatment and outcomes in patients with congenital cricoid cartilage malformation. METHODS: Retrospective analysis of patients with diagnosis of congenital cricoid malformation (CCM) treated in a single tertiary pediatric referral center between 1985 and 2022. Patients were grouped according to the morphology of the cricoid cartilage that was diagnosed during endoscopy. We reviewed the treatment strategy(s), decannulation rate, complications, and functional outcomes. RESULTS: Twenty-nine patients were grouped into four morphological subtypes of cricoid cartilage: 10 patients had a hypoplastic cricoid, eight had an elliptic shape, five had severe anterior thickening, and six an accentuated V-shape posterior cricoid plate. Twenty-four patients underwent surgery, and five were closely followed up without surgical treatment. Eight patients had a tracheostomy prior to surgery, and the majority had a hypoplastic cricoid. Most patients (20 out of 24) required additional procedures postoperatively to achieve an age-appropriate airway. Thirteen patients needed endoscopic dilatation(s) and granulation tissue removal; four needed more aggressive treatment, and three patients required revision open surgery. Decannulation was achieved after a median of 4.5 months in all previously tracheostomized patients. Endoscopy at the last follow-up showed an age-appropriate airway in 27 patients; 20 patients had normal oral feeding, and 11 patients had a normal voice. CONCLUSION: Endoscopy is important to diagnose CCM and most of the time patients would need only watchful waiting. In this report, surgery was required for patients who continued to remain symptomatic and had a compromised airway. The type of surgery depends on the type of cricoid malformation and the grade of stenosis. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:3185-3191, 2023.
