Objectives/Hypothesis Evaluate and compare surgical outcomes of slide tracheoplasty for the treatment of congenital tracheal stenosis in children with and without pulmonary malformations. Study Design Retrospective chart review at a tertiary care pediatric medical center. Methods We identified patients with tracheal stenosis who underwent slide tracheoplasty from 2001 to 2014, and a subset of these patients who were diagnosed with congenital pulmonary malformations. Hospital course and preoperative and postoperative complications were recorded. Results One hundred thirty patients (18 with pulmonary malformations, 112 with normal pulmonary anatomy) were included. Pulmonary malformations included unilateral pulmonary agenesis (61%) and hypoplasia (39%). Children with pulmonary malformations had a greater median age compared to their normal lung anatomy counterparts. Preoperatively, patients with pulmonary malformations more frequently required preoperative mechanical ventilation (55.6% vs. 21.3%, P = .007), extracorporeal membrane oxygenation (ECMO) (11% vs. 0.9%, P = .05), and tracheostomy (22.2% vs. 3.6%, P = .01). Postoperatively, patients with pulmonary malformations more frequently required mechanical ventilation >48 hours (78% vs. 37%, P =.005) and ECMO use (11% vs. 0.9%, P = .05). Pulmonary malformation patients and children with normal anatomy did not differ in terms of postoperative tracheostomy (16.7% vs. 4.4%, P > .05), dehiscence (6% vs. 0%, P > .05%), restenosis (11% vs. 6%, P > .05) or postoperative figure 8 deformity (6% vs. 3%, P > .05). Mortality, however, was significantly increased (22.2% vs. 3.6%, P = .01) in children with pulmonary malformations. Conclusions Although slide tracheoplasty can be successfully performed in patients with abnormal pulmonary anatomy, surgeons and families should anticipate a more difficult postoperative course, with possible associated prolonged mechanical ventilation, ECMO use, and higher mortality than in children with tracheal stenosis alone.

When a system which contains a dipole, and whose dimensionality is less than three, is studied in a code which imposes periodic boundary conditions in all three dimensions, an artificial electric field arises which keeps the potential periodic. This has an impact on the total energy of the system, and on any other attribute which would respond to an electric field. Simple corrections are known for 0D systems embedded in a cubic geometry, and 2D slab systems. This paper shows how the 0D result can be extended to tetragonal geometries, and that for a particular $c/a$ ratio the correction is zero. It also considers an exponential error term absent from the usual consideration of 2D slab geometries, and discusses an empirical form for this., 10 pages. Figure 3 corrected in this version

Differentiated thyroid cancer (DTC) is the most common cancer in adolescents and young adults. In 2015, the American Thyroid Association published guidelines for management of pediatric DTC. We report our institutional experience and highlight changing practices and new opportunities. A retrospective analysis of all patients diagnosed with DTC from 2001 to 2016 was performed. Among 59 eligible patients, 31 (53%), 15 (25%), and 13 (22%) had low-risk, intermediate-risk, and high-risk disease, respectively. Half (15/31) of low-risk and all intermediate-risk/high-risk patients received radioactive iodine (I-131) ablation. For low-risk patients, average I-131 dose decreased from 80 to 42.05 mCi, and the percentage of patients who received I-131 decreased over time. Eleven of 16 patients with tumor genomic data were found to have somatic targetable (n=6) or germline (n=5) mutations. Persistent/recurrent disease was only present in high-risk (n=8) and intermediate-risk (n=1) patients. Two patients with iodine-refractory disease received trametinib to enhance radioiodine uptake. All patients were alive at follow-up (median, 5 y; range, 1 to 15 y). Coincident with the recent American Thyroid Association guidelines, the use of I-131 in low-risk patients has decreased over time in our practice. Tumor sequencing and cancer genetic evaluation may help redefine opportunities for treatment of high-risk patients and family counseling.

This study documents the growth and course of repaired complete tracheal rings over time after slide tracheoplasty.Case series with review.Tertiary pediatric academic medical center.Medical records of pediatric patients with confirmed tracheal rings on bronchoscopy who underwent slide tracheoplasty between January 2001 and December 2015 were reviewed. Patients who had operative notes documenting tracheal sizing over time were included. Exclusion criteria included tracheal stenosis not caused by complete tracheal rings, surgical repair prior to presentation at our institution, or lack of adequate sizing information. The postoperative follow-up was examined and airway growth over time documented.Of 197 slide tracheoplasties performed during the study time period, 139 were for complete tracheal rings, and 40 of those children met inclusion criteria. The median age at time of surgery was 7 months, and the median initial airway size was 3.9 mm (n = 34). The median growth postoperatively was 1.9 mm over a median follow-up period of 57 months (0.42 mm/year), which is similar to growth rates of unrepaired complete tracheal rings (This is the first study documenting continued growth of repaired complete tracheal rings after slide tracheoplasty. Postoperative endoscopic surveillance ensures adequate growth. Intervals between airway endoscopies can be increased as the child gets older, as the airway increases in size, and as long as symptoms are minimal.

Objective To provide recommendations to otolaryngologists and allied physicians for the comprehensive management of young infants who present with signs or symptoms of choanal atresia. Methods A two-iterative delphi method questionnaire was used to establish expert recommendations by the members of the International Otolaryngology Group (IPOG), on the diagnostic, intra-operative, post-operative and revision surgery considerations. Results Twenty-eight members completed the survey, in 22 tertiary-care center departments representing 8 countries. The main consensual recommendations were: nasal endoscopy or fiberscopy and CT imaging are recommended for diagnosis; unilateral choanal atresia repair should be delayed after at least age 6 months whenever possible; transnasal endoscopic repair is the preferred technique; long term follow-up is recommended (minimum one year) using nasal nasofiberscopy or rigid endoscopy, without systematic imaging. Conclusion Choanal atresia care consensus recommendations are aimed at improving patient-centered care in neonates, infants and children with choanal atresia.

Chronic epiglottitis and supraglottitis are clinical entities that present with respiratory distress and are primarily associated with autoimmune disorders, gastroesophageal reflux disease, or angioedema. First described in adults with sarcoidosis in 2010, CO2 laser epiglottis resurfacing has been effective in reducing epiglottic edema. We present two cases of adolescent males with non-granulomatous chronic supraglottitis who were successfully treated with CO2 laser supraglottic resurfacing.

This article reviews congenital anomalies involving the larynx and trachea, including congenital subglottic stenosis, laryngeal webs, laryngeal cleft, and tracheal stenosis. Presenting signs and symptoms, prevailing surgical repair techniques, and postoperative care are discussed.

Objectives To provide recommendations to otolaryngologists, pulmonologists, and allied clinicians for tracheostomy decannulation in pediatric patients. Methods An iterative questionnaire was used to establish expert recommendations by the members of the International Pediatric Otolaryngology Group. Results Twenty-six members completed the survey. Recommendations address patient criteria for decannulation readiness, airway evaluation prior to decannulation, decannulation protocol, and follow-up after both successful and failed decannulation. Conclusion Tracheostomy decannulation recommendations are aimed at improving patient-centered care, quality and safety in children with tracheostomies.

Introduction Suprastomal Collapse (SuStCo) is a common complication of prolonged tracheostomy in children. There is a paucity of literature on this subject, especially regarding how to manage significant suprastomal collapse that prevents safe decannulation. Objective Provide a definition, classification system, and recommend management options for significant suprastomal collapse in children with tracheostomy. Methods Members of the International Pediatric Otolaryngology Group (IPOG) who are experts in pediatric airway conditions were surveyed and results were refined using a modified Delphi method. Results Consensus was defined as > 70% agreement on a subject. The experts achieved consensus: • on a standard definition of Suprastomal Collapse • that there is clinical importance between significant and insignificant collapse • that the gold standard diagnostic modality is endoscopic examination under anesthesia • that the severity of collapse is a major determinant in the surgical approach • that surgical intervention is the first line management in combined anterior and lateral Suprastomal Collapse. Conclusion This consensus statement provides recommendations for medical specialists who manage infants and children with tracheostomies with significant Suprastomal Collapse. It provides a classification system to facilitate diagnosis and treatment options for this condition.

Objective To make recommendations on the identification, routine evaluation, and management of fetuses at risk for airway compromise at delivery. Methods Recommendations are based on expert opinion by members of the International Pediatric Otolaryngology Group (IPOG). A two-iterative Delphi method questionnaire was distributed to all members of the IPOG and responses recorded. The respondents were given the opportunity to comment on the content and format of the survey, which was modified for the second round. “Consensus” was defined by >80% respondent affirmative responses, “agreement” by 51–80% affirmative responses, and “no agreement” by 50% or less affirmative responses. Results Recommendations are provided regarding etiologies of perinatal airway obstruction, imaging evaluation, adjunct evaluation, multidisciplinary team and decision factors, micrognathia management, congenital high airway obstruction syndrome management, head and neck mass management, attended delivery procedure, and delivery on placental support procedure. Conclusions Thorough evaluation and thoughtful decision making are required to optimally balance fetal and maternal risks/benefits.

Purpose Severe esophageal disease warranting replacement often presents with additional airway anomalies in children. Colon interposition and airway reconstruction have separately proven successful in attaining satisfactory outcomes. The aim of this study was to determine outcomes associated with an interdisciplinary approach to care of the patient with complex esophageal and airway disease. Methods After IRB approval, a retrospective cohort study was performed spanning 2011 through 2015. Eleven patients underwent colon interposition and airway surgery. Review of medical records was performed, extracting patient demographics, clinical and operative courses and outcomes. Results The mean age of patients was 44months (range 2–108). 91% (n=10) were transferred to our institution with primary diagnoses of caustic ingestion (45%, n=5), long gap esophageal atresia (27% n=3), tracheoesophageal fistula (18%, n=2) and necrotizing pharyngitis (9% n=1). All patients had associated airway anomalies. Pulmonology, gastroenterology and speech therapy were involved in preoperative evaluation and postoperative care of all patients. Intraoperatively, a multi-team approach was utilized. The most common postoperative complication was esophageal stricture (54%, n=6). All patients are capable of taking some to full nutrition per orum. Conclusion Colonic interposition with major airway reconstruction at our institution attains satisfactory functional results through utilization of a multidisciplinary approach.

A case report of a 10 year old male illustrates the effect of damage to the tongue base, hypopharynx, cricopharyngeus, and esophagus on the sensory and motor components of the swallowing mechanism. The characteristics of the dysphagia were manifested clinically, radiographically, and endoscopically. A myectomy was required to restore functional swallowing as scar tissue formation in the cricopharyngeus severely interfered with the dynamic components of swallowing. A collaborative approach facilitated communication and effective treatment planning; the multidisciplinary components in the management of this case are discussed.

Objective To provide recommendations for the comprehensive management of young infants who present with signs or symptoms concerning for laryngomalacia. Methods Expert opinion by the members of the International Pediatric Otolaryngology Group (IPOG). Results Consensus recommendations include initial care and triage recommendations for health care providers who commonly evaluate young infants with noisy breathing. The consensus statement also provides comprehensive care recommendations for otolaryngologists who manage young infants with laryngomalacia including: evaluation and treatment considerations for commonly debated issues in laryngomalacia, initial work-up of infants presenting with inspiratory stridor, treatment recommendations based on disease severity, management of the infant with feeding difficulties, post-surgical treatment management recommendations, and suggestions for acid suppression therapy. Conclusion Laryngomalacia care consensus recommendations are aimed at improving patient-centered care in infants with laryngomalacia.

Subglottic stenosis (SGS) is a congenital or acquired condition characterized by a narrowing of the upper airway extending from just below the vocal folds to the lower border of the cricoid cartilage. With the introduction of prolonged intubation in neonates (mid 1960s), acquired SGS became the most frequent cause of laryngeal stenosis; unlike congenital SGS, it does not improve with time. Laryngeal reconstruction surgery evolved as a consequence of the need to manage these otherwise healthy but tracheotomized children. Ongoing innovations in neonatal care have gradually led to the salvage of premature and medically fragile infants in whom laryngeal pathology is often more severe, and in whom stenosis often involves not only the subglottis, but also the supraglottis or glottis-causing significant morbidity and mortality. The primary objective of intervention in these children is decannulation or preventing the need for tracheotomy. The aim of this article is to present a more detailed description of both congenital and acquired SGS, highlighting the essentials of diagnostic assessment and familiarizing the reader with contemporary management approaches.

Although suprastomal granulomas are a common complication of tracheotomy, they usually are an incidental finding and do not always require treatment. However, large granulomas may require removal, either to assist with speech production or to make the airway safer in the event of an accidental decannulation. Very large suprastomal granulomas extending up to or even through the vocal cords have been described. However, inverting suprastomal granulomas extending distally down the length of a tracheotomy tube have not been previously described. We present two cases of large suprastomal granulomas that extended distally down the trachea. Both extended beyond the tip of the tracheotomy tube, causing partial airway obstruction, and therefore required excision. Laryngoscope, 127:2883–2885, 2017

Chondrodysplasia punctata is a group of congenital bone and cartilage disorders characterized by erratic calcification during development. Laryngeal and tracheal calcification and subsequent stenosis, while being reported in several cases of chondrodysplasia punctata, are not frequent findings and there are no proposed management techniques. We describe here a case of an infant with chondrodysplasia punctata associated to tracheal stenosis that was successfully treated with balloon dilation, and with long term follow-up.

Importance Surgical treatment comparisons in rare diseases are difficult secondary to the geographic distribution of patients. Fortunately, emerging technologies offer promise to reduce these barriers for research. Objective To prospectively compare the outcomes of the 3 most common surgical approaches for idiopathic subglottic stenosis (iSGS), a rare airway disease. Design, Setting, and Participants In this international, prospective, 3-year multicenter cohort study, 810 patients with untreated, newly diagnosed, or previously treated iSGS were enrolled after undergoing a surgical procedure (endoscopic dilation [ED], endoscopic resection with adjuvant medical therapy [ERMT], or cricotracheal resection [CTR]). Patients were recruited from clinician practices in the North American Airway Collaborative and an online iSGS community on Facebook. Main Outcomes and Measures The primary end point was days from initial surgical procedure to recurrent surgical procedure. Secondary end points included quality of life using the Clinical COPD (chronic obstructive pulmonary disease) Questionnaire (CCQ), Voice Handicap Index-10 (VHI-10), Eating Assessment Test-10 (EAT-10), the 12-Item Short-Form Version 2 (SF-12v2), and postoperative complications. Results Of 810 patients in this cohort, 798 (98.5%) were female and 787 (97.2%) were white, with a median age of 50 years (interquartile range, 43-58 years). Index surgical procedures were ED (n = 603; 74.4%), ERMT (n = 121; 14.9%), and CTR (n = 86; 10.6%). Overall, 185 patients (22.8%) had a recurrent surgical procedure during the 3-year study, but recurrence differed by modality (CTR, 1 patient [1.2%]; ERMT, 15 [12.4%]; and ED, 169 [28.0%]). Weighted, propensity score–matched, Cox proportional hazards regression models showed ED was inferior to ERMT (hazard ratio [HR], 3.16; 95% CI, 1.8-5.5). Among successfully treated patients without recurrence, those treated with CTR had the best CCQ (0.75 points) and SF-12v2 (54 points) scores and worst VHI-10 score (13 points) 360 days after enrollment as well as the greatest perioperative risk. Conclusions and Relevance In this cohort study of 810 patients with iSGS, endoscopic dilation, the most popular surgical approach for iSGS, was associated with a higher recurrence rate compared with other procedures. Cricotracheal resection offered the most durable results but showed the greatest perioperative risk and the worst long-term voice outcomes. Endoscopic resection with medical therapy was associated with better disease control compared with ED and had minimal association with vocal function. These results may be used to inform individual patient treatment decision-making.

OBJECTIVES 1) Evaluate success rates for adults undergoing cervical slide tracheoplasty. 2) Examine complication rates of slide tracheoplasty in adults. METHODS A retrospective cohort of adults > 21 years of age undergoing cervical slide tracheoplasty for tracheal stenosis between October 2011 and August 2017 was reviewed. Comorbidities, stenosis grade, etiology of stenosis, primary versus revision surgery, complications, and number of adjunct endoscopic procedures required postoperatively were evaluated. RESULTS Nineteen patients (63% female) underwent cervical slide tracheoplasty during the study period (median age 30 years, range 21-70). The most common etiology of stenosis was iatrogenic (68%), followed by congenital etiologies (26%). Fifty-eight percent of patients had undergone a previous open airway procedure. Thirty-nine percent were tracheostomy-dependent prior to surgery, and the remainder had severe exercise intolerance. Sixty-three percent were successfully extubated on the operating room table at the end of the procedure. Six (32%) patients experienced surgical complications, including one anastomotic dehiscence, three neck abscesses requiring incision and drainage (I&D), and replacement of adjunctive airway device in two patients. Seventy percent of the patients required ≥ 1 endoscopic dilation in the first 12 months following surgery, with a median of one (range 1-8) procedure. At most recent follow-up (median 8 months, range 4-64 months), 18 of 19 (95%) of patients had minimal airway symptoms without need for tracheostomy. The one patient who was not decannulated expired of a presumed cardiac event prior to decannulation. CONCLUSION Cervical slide tracheoplasty is an excellent reconstructive option for adult patients with tracheal stenosis, including those with history of previous airway reconstruction.

Acquired laryngomalacia in the pediatric population is rare, especially from a neurogenic cause. This case report describes a pediatric patient who developed laryngomalacia following a neurologic insult. A proposed physiologic pathway is reviewed. A thorough literature review was performed to identify cases of acquired laryngomalacia ascribed to a neurologic cause and are compared to this case.

Develop multidisciplinary and international consensus on patient, disease, procedural, and perioperative factors, as well as key outcome measures and complications, to be reported for pediatric airway reconstruction studies.Standard Delphi methods were applied. Participants proposed items in three categories: 1) patient/disease characteristics, 2) procedural/intraoperative/perioperative factors, and 3) outcome measures and complications. Both general and anatomic site-specific measures were elicited. Participants also suggested specific operations to be encompassed by this project. We then used iterative ranking and review to develop consensus lists via a priori Delphi consensus criteria.Thirty-three pediatric airway experts from eight countries in North and South America, Europe, and Australia participated, representing otolaryngology (including International Pediatric Otolaryngology Group members), pulmonology, general surgery, and cardiothoracic surgery. Consensus led to inclusion of 19 operations comprising open expansion, resection, and slide procedures of the larynx, trachea, and bronchi as well as three endoscopic procedures. Consensus was achieved on multiple patient/comorbidity (10), disease/stenosis (7), perioperative-/intraoperative-/procedure-related (16) factors. Consensus was reached on multiple outcome and complication measures, both general and site-specific (8 general, 13 supraglottic, 15 glottic, 17 subglottic, 8 cervical tracheal, 12 thoracic tracheal). The group was able to clarify how each outcome should be measured, with specific instruments defined where applicable.This consensus statement provides a framework to communicate results consistently and reproducibly, facilitating meta-analyses, quality improvement, transfer of information, and surgeon self-assessment. It also clarifies expert opinion on which patient, disease, procedural, and outcome measures may be important to consider in any pediatric airway reconstruction patient.5 Laryngoscope, 129:244-255, 2019.

Aerodigestive programs provide coordinated interdisciplinary care to pediatric patients with complex congenital or acquired conditions affecting breathing, swallowing, and growth. Although there has been a proliferation of programs, as well as national meetings, interest groups and early research activity, there is, as of yet, no consensus definition of an aerodigestive patient, standardized structure, and functions of an aerodigestive program or a blueprint for research prioritization. The Delphi method was used by a multidisciplinary and multi-institutional panel of aerodigestive providers to obtain consensus on 4 broad content areas related to aerodigestive care: (1) definition of an aerodigestive patient, (2) essential construct and functions of an aerodigestive program, (3) identification of aerodigestive research priorities, and (4) evaluation and recognition of aerodigestive programs and future directions. After 3 iterations of survey, consensus was obtained by either a supermajority of 75% or stability in median ranking on 33 of 36 items. This included a standard definition of an aerodigestive patient, level of participation of specific pediatric disciplines in a program, essential components of the care cycle and functions of the program, feeding and swallowing assessment and therapy, procedural scope and volume, research priorities and outcome measures, certification, coding, and funding. We propose the first consensus definition of the aerodigestive care model with specific recommendations regarding associated personnel, infrastructure, research, and outcome measures. We hope that this may provide an initial framework to further standardize care, develop clinical guidelines, and improve outcomes for aerodigestive patients.

Decannulation readiness is approached in several ways and is tailored to the individual patient. While microlaryngoscopy and bronchoscopy evaluate airway patency at all levels, polysomnography assesses sleep-related upper airway physiology. There are limited data in the literature on the utility of these tools. Thus, the main objectives of this study were (1) to identify sleep and respiratory parameters associated with successful decannulation and (2) to determine the agreement between microlaryngoscopy and bronchoscopy and polysomnography.Case series with chart review.Quaternary care pediatric hospital.A retrospective review of medical records, microlaryngoscopy and bronchoscopy, and polysomnographs was performed on subjects preparing for decannulation from 2005 to 2010. Fifty-nine subjects who underwent overnight polysomnography with a tracheostomy capping trial and microlaryngoscopy and bronchoscopy were included. Prediction of successful decannulation from polysomnography parameters was determined using logistic regression analysis.Fifty-nine subjects with a total of 78 polysomnographs were subdivided into 2 groups: 42 polysomnographs were classified as successfully decannulated, and 36 polysomnographs belonged to the group that did not decannulate. Logistic regression analysis determined that the Apnea Hypopnea Index (P = .0423) and maximal end-tidal CO2 (P = .046) were significant predictors for successful decannulation.Airway evaluation by microlaryngoscopy and bronchoscopy is an essential tool in the assessment of decannulation readiness. Polysomnography is an important additional tool for children with complex airway problems. Our results indicate that certain polysomnographic parameters such as Apnea Hypopnea Index and maximal end-tidal CO2 are valuable in predicting successful tracheostomy decannulation.

Objectives Suprastomal stents are routinely used in laryngotracheal reconstruction (LTR) to stabilize grafts and provide framework to sites of repair. However, the duration of stenting varies according to patient history and physician preference. We examined outcomes of short- versus long-term stenting in children with subglottic stenosis (SGS) undergoing LTR. Study Design Case series with chart review. Setting Tertiary care pediatric hospital. Subjects and Methods Thirty-six children18 years old who underwent double-stage LTR for SGS from January 2012 to January 2015 were included. Demographic data, stenosis grade, and decannulation rates were compared between children with short-term stenting (≤21 days; n = 14) and those with long-term stenting (21 days; n = 22). Results No significant difference between groups was seen for sex, age, race, or previous repair. Children in the short-term group were stented for 10.9 ± 4.9 days, compared with 44.0 ± 10.6 for those long-term ( P.0001). A similar number of children with short- versus long-term stents had grade 3/4 stenosis preoperatively (71.4% vs 77.2%). Although time to decannulation was not significantly different, 72.7% of children with long-term stents were decannulated, as opposed to 35.7% with short-term stents ( P = .03). After adjusting for grade at surgery and age, children with long-term stents had 4.3 greater odds (95% CI, 1.0-18.3) of decannulation than children with short-term stents. Conclusions Children with long-term stenting were more likely to be successfully decannulated. Although long-term stenting improved outcomes for children with SGS, additional research is needed to better define ideal candidates for short- versus long-term stenting.

Over the past decade, thoracic slide tracheoplasty (TST) has become the principal operation in the management of congenital tracheal stenosis. The purpose of this report was to describe our experience with revision TST following unsuccessful prior tracheal reconstruction.Retrospective analysis at an academic children's hospital.Patients undergoing TST on cardiopulmonary bypass between January 2005 and May 2014 were reviewed. Patients with a history of prior airway surgery were extracted for further analysis. Preoperative patient variables and postoperative outcomes were evaluated and compared between patients undergoing revision slide tracheoplasty (RTST) and a control group of 26 matched patients undergoing primary surgery TST.Twenty-six revision patients (25 referrals, one primary patient) of 162 patients reviewed over the study period met inclusion criteria. Twenty-three patients had a history of complete tracheal rings, and three patients had cartilaginous deficiency. A total of 41 airway reconstruction procedures had been performed prior to RTST. When compared to primary TST, patients undergoing RTST required fewer cardiac procedures intraoperatively, and fewer mean ventilator hours (P = .01) postoperatively. There was no significant difference in the median length of stay, requirement of48 hours ventilation, or postoperative complications between groups. There was one nonsurgical postoperative mortality following RTST.Despite some differences in the postoperative management when compared to nonrevision cases, revision TST can be successfully performed after prior tracheal reconstruction with good postoperative outcomes.4. Laryngoscope, 128:2181-2186, 2018.

Congenital deficiency of distal tracheal rings is a rare anomaly and has been previously reported in the literature. Here we report the first case deficient tracheal rings confined to the cervical trachea. Patient was transferred to our institution for management of what was initial thought to be complete tracheal rings. The patient was successfully managed with a tracheal resection and short segment cervical slide tracheoplasty. Presentation, surgical approach, histological findings, and literature review are described.

Although tracheal stenosis and bronchial stenosis are relatively rare in the pediatric population, they are both associated with significant morbidity and mortality. While most cases of congenital tracheal stenosis in children present as complete tracheal rings (CTRs), other congenital tracheal obstructions are also encountered in clinical practice. In addition, acquired obstructive tracheal conditions stemming from endotracheal trauma or previous surgical interventions may occur. Many affected children also have associated cardiovascular malformations, further complicating their management. Optimal management of children with tracheal or bronchial stenoses requires comprehensive diagnostic evaluation and optimization prior to surgery. Slide tracheoplasty has been the operative intervention of choice in the treatment of the majority of these children.

Introduction: The purpose of this study was to report our clinical experience in the surgical management of patients with posterior glottic diastasis (PGD) secondary to prolonged intubation and/or laryngotracheoplasty (LTP) during childhood. Methods: We reviewed the charts of patients with a history of prolonged intubation and/or LTP who had undergone surgical correction for PGD at our institution between 2010 and 2014. We documented demographic data and pertinent information regarding medical and surgical histories. The Pediatric Voice Handicap Index (pVHI) and/or the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) were used to assess patients both before and after undergoing treatment for voice disorders. Results: Six patients met our inclusion criteria. With 1 exception, all patients with complete voice data demonstrated improvements in perceptual, patient-reported, and acoustic voice measures. There were no perioperative complications. Conclusion: Our case series demonstrates that operative intervention can lead to improved voice in carefully selected patients with PGD secondary to prolonged intubation and/or LTP during childhood. Patients exhibited postoperative improvement in loudness and vocal endurance; however, they also exhibited a degree of compromise in voice quality.

Tracheocutaneous fistula (TCF) closure is achieved by excision followed either by primary closure or healing by secondary intention. Although primary closure provides immediate resolution of the fistula, it is associated with more severe potential complications. Healing by secondary intention minimizes these potential complications; however, it is inconvenient for the patient and may be more likely to require revision surgery. We have had 2 life-threatening complications after primary closure, and as a result, we largely changed our practice pattern. We compared complication and success rates of the 2 methods since this change to determine its ramifications.Historical cohort study.Academic tertiary care pediatric otolaryngology practice. Subjects and Methods Two hundred sixteen patients who underwent TCF closure between January 2004 and August 2012.Forty-six (21.3%) fistulae were addressed by primary closure, and 170 (78.7%) were addressed by secondary intention. The complication and revision rates were not significantly different between the 2 methods (8.7% vs 10% and 8.7% vs 14.7%, respectively).In our study, we did not see any statistical differences between the 2 methods studied but could not exclude clinically important differences that may have favored one method over the other. Although our comparative results were inconclusive, we have adopted secondary closure as standard practice for management of pediatric TCF. Individual surgeons and patients may use the data presented to help guide decisions concerning which procedure is most appropriate.

Children with bilateral true vocal fold immobility (BTVFI) may present with significant airway distress necessitating tracheostomy. The objective of this study was to review our preliminary experience with the anterior-posterior cricoid split (APCS), an endoscopic intervention used as an alternative to tracheostomy in children with BTVFI.Multicenter review.A review of patients undergoing endoscopic APCS for BTVFI at four institutions was performed. Patients were evaluated for the ability to ventilate without the requirement for tracheostomy or reintubation. Additional data extracted included the duration of intubation following APCS, the requirement for additional procedures, and demographics. Surgical success was defined as the ability to avoid tracheostomy and to cap or decannulate without respiratory symptoms if a tracheostomy was present prior to APCS.Nineteen APCS procedures were performed between October 2010 and June 2016. There were 12 male patients, the mean age at APCS was 4.7 months. BTVFI was primarily idiopathic (58%) and associated with other comorbidities (74%). All patients were candidates for tracheostomy prior to APCS. Fourteen patients (74%) were considered surgical successes. Of the unsuccessful patients, three (66%) required tracheostomy following APCS, and one was treated with a posterior cartilage graft. There was one nonsurgical mortality greater than 2 months after APCS and thought to be unrelated to the airway.Endoscopic APCS appears to be a safe and effective intervention for pediatric BTVFI. Under the correct circumstances, this can be performed as a single procedure, obviating tracheostomy. Further study is warranted.4. Laryngoscope, 128:257-263, 2018.

Objectives To develop consensus recommendations for peri-operative tracheotomy care in pediatric patients. Methods Expert opinion by the members of the International Pediatric Otolaryngology Group (IPOG). The mission of the IPOG is to develop expertise-based consensus recommendations for the management of pediatric otolaryngologic disorders with the goal of improving patient care. The consensus recommendations herein represent the first publication by the group. Results Consensus recommendations including pre-operative, intra-operative, and post-operative considerations, as well as sedation and nutrition management are described. These recommendations are based on the collective opinion of the IPOG members and are targeted to (i) otolaryngologists who perform tracheotomies on pediatric patients, (ii) intensivists who are involved in the shared-care of these patients, and (iii) allied health professionals. Conclusion Pediatric peri-operative tracheotomy care consensus recommendations are aimed at improving patient-centered care in this patient population.

Evaluate and compare surgical outcomes of slide tracheoplasty for the treatment of congenital tracheal stenosis in children with and without pulmonary malformations.Retrospective chart review at a tertiary care pediatric medical center.We identified patients with tracheal stenosis who underwent slide tracheoplasty from 2001 to 2014, and a subset of these patients who were diagnosed with congenital pulmonary malformations. Hospital course and preoperative and postoperative complications were recorded.One hundred thirty patients (18 with pulmonary malformations, 112 with normal pulmonary anatomy) were included. Pulmonary malformations included unilateral pulmonary agenesis (61%) and hypoplasia (39%). Children with pulmonary malformations had a greater median age compared to their normal lung anatomy counterparts. Preoperatively, patients with pulmonary malformations more frequently required preoperative mechanical ventilation (55.6% vs. 21.3%, P = .007), extracorporeal membrane oxygenation (ECMO) (11% vs. 0.9%, P = .05), and tracheostomy (22.2% vs. 3.6%, P = .01). Postoperatively, patients with pulmonary malformations more frequently required mechanical ventilation48 hours (78% vs. 37%, P =.005) and ECMO use (11% vs. 0.9%, P = .05). Pulmonary malformation patients and children with normal anatomy did not differ in terms of postoperative tracheostomy (16.7% vs. 4.4%, P.05), dehiscence (6% vs. 0%, P.05%), restenosis (11% vs. 6%, P.05) or postoperative figure 8 deformity (6% vs. 3%, P.05). Mortality, however, was significantly increased (22.2% vs. 3.6%, P = .01) in children with pulmonary malformations.Although slide tracheoplasty can be successfully performed in patients with abnormal pulmonary anatomy, surgeons and families should anticipate a more difficult postoperative course, with possible associated prolonged mechanical ventilation, ECMO use, and higher mortality than in children with tracheal stenosis alone.4.

BACKGROUND AND OBJECTIVES: Pressure ulcers are commonly acquired in pediatric institutions, and they are a key indicator of the standard and effectiveness of care. We recognized a high rate of tracheostomy-related pressure ulcers (TRPUs) in our ventilator unit and instituted a quality improvement program to develop and test potential interventions for TRPU prevention, condensed them into a clinical bundle, and then implemented the bundle into our standard practice. METHODS: The intervention model used a rapid-cycle, Plan-Do-Study-Act (PDSA), framework for improvement research. All tracheostomy-dependent patients admitted to our 18-bed ventilator unit from July 2008 through December 2010 were included. TRPU stage and description, number of days each TRPU persisted, and bundle compliance were recorded in real time. All TRPUs were staged by a wound-care expert within 24 hours. The interventions incorporated into the TRPU-prevention bundle included frequent skin and device assessments, moisture-reducing device interface, and pressure-free device interface. RESULTS: There was a significant decrease in the rate of patients who developed a TRPU from 8.1% during the preintervention period, to 2.6% during bundle development, to 0.3% after bundle implementation. There was a marked difference between standard and extended tracheostomy tubes in TRPU occurrence (3.4% vs 0%, P = .007) and days affected by a TRPU (5.2% vs 0.1%, P < .0001). CONCLUSIONS: Education and ongoing assessment of skin integrity and the use of devices that minimize pressure at the tracheostomy–skin interface effectively reduce TRPU even among a population of children at high risk. These interventions can be integrated into daily workflow and result in sustained effect.

This article presents an overview of the diagnosis and management of airway problems encountered in infants with severe bronchopulmonary dysplasia (BPD). Respiratory failure in premature infants develops as a result of parenchymal and airway diseases. The survival of increasingly premature infants and the ventilatory support required by premature lungs may result in airway disease. The management of respiratory failure depends on whether it is primarily caused by parenchymal versus airway diseases. Continuous airway pressure early in the neonatal period has favorably changed the incidence of BPD. This article discusses the indications, timing, and guidelines for care of tracheotomy.

ObjectivesThis study describes results of tracheal reconstruction in children with slide tracheoplasty with cardiopulmonary bypass and identifies predictors for adverse outcomes.MethodsPreoperative characteristics, operative variables, and outcome measures were collected for children undergoing slide tracheoplasty with cardiopulmonary bypass between April 2001 and October 2009. Predictors of worse outcomes were identified by bivariate analysis. Multiple regression analysis was performed for predictors of prolonged hospital stay.ResultsCohort included 80 patients (median age, 8.7 months; 7 days–21 years). Forty-eight patients had associated cardiac or great vessel anomalies; 24 had simultaneous repair of cardiovascular anomaly at tracheal reconstruction. Fifty (63%) were extubated within 48 hours after operation. Median stay was 18.5 days (range, 7–119 days). Twenty-three patients (29%) required significant airway reintervention during median follow-up of 12 months (range, 4 months–7.8 years). There were 4 deaths, 2 early and 2 late. In bivariate analysis, age (P = .017), cardiopulmonary bypass duration (P = .025), and duration of mechanical ventilation (P

Partial cricotracheal resection (CTR) for the treatment of subglottic stenosis has been reported, in children, with decannulation rates of 90% for refractory grades 3 and 4 stenoses. In view of these findings, it has become imperative for pediatric otolaryngologists to add CTR to their surgical armamentarium for the management of severe subglottic stenosis. The authors have described preoperative evaluation, patient selection, operative technique, and possible complications of CTR in this article.

Objectives/Hypothesis: Thyroglossal duct cysts (TGDC) are uncommon congenital midline neck masses arising from tubal remnants of embryologic thyroid descent. A rare variant of TGDC can present in the central tongue base and is named lingual TGDC (LTGDC). Left untreated, LTGDC may present with life-threatening airway obstruction. TGDC require surgery for cure; however, the surgical approach to LTGDC has not been discussed fully. This study was designed to examine the incidence, clinical features, and surgical management of LTGDC. Study Design: Retrospective chart review. Methods: Retrospective chart review of patients from a pediatric tertiary care institution diagnosed with lingual TGDC from 1997 to 2008. Results: One hundred eighty-nine patients underwent surgical excision of TGDC, of which 16 (8.5%; mean age, 3 years) presented with lingual TGDC alone. Most lingual TGDC were discovered incidentally, although seven patients (44%) presented with moderate to severe upper airway obstruction. Endoscopic transoral excision was performed in each case. This included suspension laryngoscopy with electrocautery, electrocautery, and cold dissection, or a combination of microdebridement and electrocautery. Most patients were intubated electively overnight for airway protection. All patients recovered without complication and have shown no evidence of recurrence (median follow-up, 3.7 years). Two LTGDC cases were revisions of prior surgeries (marsupialization and an open procedure) performed at outside hospitals. Conclusions: Although rare, LTGDC frequently present as a prominent tongue base mass with the potential of life-threatening airway obstruction. Herein we described the typical presentation, workup, and ideal surgical approach of these lesions. Complete surgical extirpation can be performed successfully with endoscopic techniques and minimal risk of complication or recurrence.

Tracheobronchial separation (TBS) due to blunt chest trauma in children is extremely rare. We report the case of a 14-year-old boy who fell 20 feet and developed respiratory distress, bilateral pneumothoraces, pneumomediastinum, and subcutaneous emphysema. Computed tomography imaging at the initial institution failed to detect tracheobronchial disruption, and the patient was managed conservatively. The patient's worsening condition prompted bronchoscopic examination which revealed complete separation of the right main bronchus from the trachea. Single-lung ventilation was instituted using a fabricated extra-long nasotracheal tube due to the patient's large size and mandibular fracture, and the airway was primarily anastamosed with an open thoracotomy approach. The clinical features of tracheobronchial separation as well as anesthetic, clinical and surgical management of this rare but life-threatening injury are described.

Objective Arytenoid prolapse is a potential source of upper airway obstruction following laryngotracheoplasty, and may be difficult to identify. We explored the incidence, clinical features, etiology, and surgical approach to patients with arytenoid prolapse following laryngotracheoplasty. Study Design Case series with chart review. Subjects and Methods The charts of 93 patients diagnosed with arytenoid prolapse following laryngotracheoplasty from 1981 to 2007 were reviewed. Results The incidence was 5.7 percent (93/1634). Forty-nine patients had unilateral prolapse; 44 had bilateral prolapse. Average time from laryngotracheoplasty to presentation was 36.8 months. Common symptoms were dyspnea on exertion, tracheostomy dependence, and sleep-disordered breathing. Fifty-four patients (58%) required surgical intervention, with arytenoid reduction performed in 45 patients. Nine underwent reduction during revision laryngotracheoplasty or cricotracheal resection. Fourteen patients required a second procedure for persistent prolapse. Thirty-nine (42%) required no intervention. Symptom resolution or decannulation was achieved in all patients in whom prolapse was the source of obstruction. Statistically significant differences were found when anterior vs posterior graft utilization was compared. Conclusions Arytenoid prolapse is a cause of airway obstruction following laryngotracheoplasty. Subtle airway complaints and decannulation failures are common features. Both endoscopic and open procedures can successfully treat arytenoid prolapse. Potential etiologies are discussed.

Summary Aims: To better inform the preoperative anesthesia assessment, we review the rationale of tracheal T-tubes and the maintenance they require. We then describe specific intraoperative techniques to administer inhalational agents and maintain respiration in patients with tracheal T-tubes. Background: Tracheal T-tubes maintain airway patency in the healing phases of laryngotracheal reconstruction or in the setting of extrinsic or intrinsic airway collapse. The T-tube comprises a superior limb, an inferior limb, and an anterior limb projecting from a tracheotomy site. Negotiating tracheal T-tubes may present significant anesthetic challenges in both elective and emergent circumstances. Methods: The intraoperative ventilation techniques in patients with tracheal T-tubes are reviewed as well as pre and postoperative T-tube maintenance strategies. Results: Twelve techniques to connect anesthetic circuitry to tracheal T-tubes in different perioperative clinical scenarios are detailed. Conclusions: T-tubes are a well-established method for supporting the airway in both adults and children. However, the very design of the T-tube poses unique anesthetic management issues before, during, and after the operation. Anesthetic administration and gas exchange may be effectively achieved through a variety of methods, which we describe in detail.

Summary Necrotizing fasciitis is a rare, life-threatening infection. We report a case of necrotizing oropharyngitis caused by Serratia marcescens in a previously immunocompetent 6-year-old male. This necrotizing infection led to a near-total defect of the oropharynx. The wound was managed with daily wound debridement of the patient’s oropharynx with 3% hydrogen peroxide, carotid artery coverage with Kaltostat™, and pharyngeal packing with iodoform ribbon gauze. Our patient’s resultant nasopharyngeal and hypopharyngeal stenoses present challenges for restoration of form and function for voicing and deglutition. We present our experience of managing this child’s hypopharyngeal stenosis with a minimally invasive double-balloon dilatation technique.

To discuss the current status of endoscopic airway surgery in children.More refined endoscopic instruments have been introduced, including balloon dilators, powered debriders, lasers with more exact modes of delivery, and innovative suspension laryngoscopes. The use of balloon dilatation for primary management of acquired subglottic stenosis is promising. Microdebriders are now considered a viable option to the CO2 laser for the management of a number of airway diseases. Knowledge regarding supraglottoplasty continues to evolve. Endoscopic vocal cord lateralization is being successfully used at some centers for the management of bilateral vocal cord paralysis. The da Vinci Surgical Robot (Intuitive Surgical, Inc., Sunnyvale, California, USA) has been introduced to facilitate endoscopic laryngeal cleft repair.Endoscopic airway surgery is presently regaining its early (1960s) popularity. This trend can be attributed to the availability of new and more sophisticated endoscopic instrumentation, the adjunctive use of new pharmaceuticals, and the realization that open and endoscopic techniques can often be used in a complementary fashion.

Surgeons who make airway reconstruction a major part of their practice inevitably are faced with children in whom initial surgical management fails. Searching for the possible causes of failure and determining how best to minimize the risk of repeated failure is often an exhaustive process. Establishing a framework and guidelines for approaching and managing these failures can improve the chances of success significantly. The aim of this article is to provide such a framework.

Background A single-institution experience with slide tracheoplasty for management of tracheal stenosis in children with emphasis on identifying predictors of prolonged postoperative mechanical ventilation is reviewed. Methods Patient characteristics, hospital course, and outcomes for children undergoing slide tracheoplasty were recorded. Univariate and multivariate analysis was performed to identify factors leading to prolonged mechanical ventilation (>48 hours postoperatively). Results Since April 2001, 40 children underwent slide tracheoplasty utilizing cardiopulmonary bypass (CPB) support at a median age of 6.2 months (range, 7 days to 15 years), and median weight of 6.1 kg (range, 1.9 to 57 kg). Thirteen patients had undergone prior operations. Thirteen patients (32.5%) were mechanically ventilated before operation. Thirteen patients underwent additional procedures at the time of the slide tracheoplasty. Mean CBP support time was 123 minutes. Seven patients required aortic cross-clamping (mean, 69 minutes). There were 2 early and 2 late deaths, none related to the tracheoplasty. One patient required repair of a recurrent tracheal stenosis, 4 patients required tracheotomy, and 3 required temporary stent placement. Twenty-one patients (52.5%) were extubated within 48 hours after tracheoplasty. Univariate and multivariate analysis revealed only preoperative mechanical ventilatory support (odds ratio 28.4, p = 0.015) and duration of CPB support (odds ratio 1.06, p = 0.007) to be significant predictors of the need for prolonged intubation. Conclusions Slide tracheoplasty utilizing CPB support is a versatile and effective treatment for tracheal stenosis in children even when combined with repair of congenital cardiac anomalies. Most children can be successfully weaned from mechanical ventilatory support early after repair.

Objectives We evaluated the efficacy of balloon dilation for adjunctive and symptomatic management of isolated idiopathic subglottic stenosis in adults. Methods Adults with airway obstruction symptoms classified as idiopathic subglottic stenosis based on history and findings of a single discrete stenotic area on microlaryngoscopy and bronchoscopy were included in this series. Patients who met these criteria underwent dilation with a 10- to 14-mm balloon in a single procedure or in 2 consecutive dilations within 7 days. The patients were followed for up to 30 months after dilation. Results Six patients met the criteria. One of the 6 had prior laser treatments and a cricotracheal resection. One patient had a previous scar band lysis procedure. The remaining 4 patients had no prior procedures. The airway sizes prior to dilation ranged from a 2.5 endotracheal tube to a 5.0 endotracheal tube. In all cases the airway was dilated to 2.0 to 3.5 endotracheal tube sizes larger than the initial size. To date, 4 patients have been followed for 10 to 30 months without symptoms of recurrent airway stenosis. One patient was symptom-free for 22 months, then presented with progressive airway difficulty following an upper respiratory tract infection, and has undergone a repeat dilation. No patients had adverse effects or complications from the procedure. Conclusions Balloon dilation of idiopathic subglottic stenosis in adults is a relatively safe and effective method to manage this disease entity for cases of isolated and discrete lesions. Patients who underwent a single procedure have remained symptom-free for up to 30 months after balloon dilation.
