Systemic Bevacizumab for Treatment of Respiratory Papillomatosis: International Consensus Statement.

OBJECTIVES/HYPOTHESIS: The purpose of this study is to develop consensus on key points that would support the use of systemic bevacizumab for the treatment of recurrent respiratory papillomatosis (RRP), and to provide preliminary guidance surrounding the use of this treatment modality. STUDY DESIGN: Delphi method-based survey series. METHODS: A multidisciplinary, multi-institutional panel of physicians with experience using systemic bevacizumab for the treatment of RRP was established. The Delphi method was used to identify and obtain consensus on characteristics associated with systemic bevacizumab use across five domains: 1) patient characteristics; 2) disease characteristics; 3) treating center characteristics; 4) prior treatment characteristics; and 5) prior work-up. RESULTS: The international panel was composed of 70 experts from 12 countries, representing pediatric and adult otolaryngology, hematology/oncology, infectious diseases, pediatric surgery, family medicine, and epidemiology. A total of 189 items were identified, of which consensus was achieved on Patient Characteristics (9), Disease Characteristics (10), Treatment Center Characteristics (22), and Prior Workup Characteristics (18). CONCLUSION: This consensus statement provides a useful starting point for clinicians and centers hoping to offer systemic bevacizumab for RRP and may serve as a framework to assess the components of practices and centers currently using this therapy. We hope to provide a strategy to offer the treatment and also to provide a springboard for bevacizumab's use in combination with other RRP treatment protocols. Standardized delivery systems may facilitate research efforts and provide dosing regimens to help shape best-practice applications of systemic bevacizumab for patients with early-onset or less-severe disease phenotypes.

Competency-Based Assessment Tool for Pediatric Esophagoscopy: International Modified Delphi Consensus.

OBJECTIVES/HYPOTHESIS: Create a competency-based assessment tool for pediatric esophagoscopy with foreign body removal. STUDY DESIGN: Blinded modified Delphi consensus process. SETTING: Tertiary care center. METHODS: A list of 25 potential items was sent via the Research Electronic Data Capture database to 66 expert surgeons who perform pediatric esophagoscopy. In the first round, items were rated as "keep" or "remove" and comments were incorporated. In the second round, experts rated the importance of each item on a seven-point Likert scale. Consensus was determined with a goal of 7 to 25 final items. RESULTS: The response rate was 38/64 (59.4%) in the first round and returned questionnaires were 100% complete. Experts wanted to "keep" all items and 172 comments were incorporated. Twenty-four task-specific and 7 previously-validated global rating items were distributed in the second round, and the response rate was 53/64 (82.8%) with questionnaires returned 97.5% complete. Of the task-specific items, 9 reached consensus, 7 were near consensus, and 8 did not achieve consensus. For global rating items that were previously validated, 6 reached consensus and 1 was near consensus. CONCLUSIONS: It is possible to reach consensus about the important steps involved in rigid esophagoscopy with foreign body removal using a modified Delphi consensus technique. These items can now be considered when evaluating trainees during this procedure. This tool may allow trainees to focus on important steps of the procedure and help training programs standardize how trainees are evaluated. LEVEL OF EVIDENCE: 5. Laryngoscope, 131:1168-1174, 2021.

Competency-Based Assessment Tool for Pediatric Tracheotomy: International Modified Delphi Consensus.

OBJECTIVES/HYPOTHESIS: Create a competency-based assessment tool for pediatric tracheotomy. STUDY DESIGN: Blinded, modified, Delphi consensus process. METHODS: Using the REDCap database, a list of 31 potential items was circulated to 65 expert surgeons who perform pediatric tracheotomy. In the first round, items were rated as "keep" or "remove," and comments were incorporated. In the second round, experts were asked to rate the importance of each item on a seven-point Likert scale. Consensus criteria were determined a priori with a goal of 7 to 25 final items. RESULTS: The first round achieved a response rate of 39/65 (60.0%), and returned questionnaires were 99.5% complete. All items were rated as "keep," and 137 comments were incorporated. In the second round, 30 task-specific and seven previously validated global rating items were distributed, and the response rate was 44/65 (67.7%), with returned questionnaires being 99.3% complete. Of the Task-Specific Items, 13 reached consensus, 10 were near consensus, and 7 did not achieve consensus. For the 7 previously validated global rating items, 5 reached consensus and two were near consensus. CONCLUSIONS: It is feasible to reach consensus on the important steps involved in pediatric tracheotomy using a modified Delphi consensus process. These items can now be considered to create a competency-based assessment tool for pediatric tracheotomy. Such a tool will hopefully allow trainees to focus on the important aspects of this procedure and help teaching programs standardize how they evaluate trainees during this procedure.

Outcome measures for pediatric laryngotracheal reconstruction: International consensus statement.

OBJECTIVES: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

Diagnosis and management of laryngotracheal stenosis.

INTRODUCTION: Laryngotracheal stenosis comprises a broad spectrum of congenital and acquired conditions that commonly cause pediatric airway obstruction. Although the majority of these conditions were historically managed with endoscopic dilations, the introduction of operative procedures such as laryngotracheoplasty, cricotracheal resection, and slide tracheoplasty changed the treatment paradigm. The gradual evolution of endoscopic technology enabled surgeons to perform certain procedures endoscopically that were previously only able to be performed in an open fashion. Areas covered: This review highlights the important aspects of the diagnosis, workup, and surgical treatment of pediatric laryngotracheal stenosis. Important articles describing research and techniques within pediatric airway reconstruction are summarized and included in the review. Expert commentary: The importance of the multidisciplinary concept of treating laryngotracheal stenosis is evidenced by the establishment of aerodigestive centers internationally. In order to continue successfully treating complex cases of laryngotracheal stenosis, further airway research is needed. The application and feasibility of tracheal transplantation and replacement is likely the next frontier in the treatment of laryngotracheal stenosis.

Structure and Functions of Pediatric Aerodigestive Programs: A Consensus Statement.

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.

Short- versus Long-term Stenting in Children with Subglottic Stenosis Undergoing Laryngotracheal Reconstruction.

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 children <18 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.

Inverting suprastomal granulomas.

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.

The Management of Cyanotic Spells in Children with Oesophageal Atresia.

Cyanotic spells, also known as blue spells, dying spells, or apparent life-threatening events, refer to a bluish tone visible in the mucosal membranes and skin caused by an oxygen decrease in the peripheral circulation. Although this decrease may be transient and benign, it may also be indicative of a severe underlying problem that requires immediate intervention. Children with oesophageal atresia (OA) are at risk for a number of coexisting conditions that may trigger cyanotic spells. This current article will focus on the management of cyanotic spells both in children with innominate artery compression and those with tracheomalacia.

Laryngotracheal Cleft Repair in Children With Complex Airway Anomalies.

IMPORTANCE: This study provides clinicians with relevant information regarding the surgical outcomes of patients with laryngotracheal cleft in the context of additional airway anomalies. OBJECTIVES: To determine the rates of surgical success in patients who underwent laryngotracheal cleft repair in the context of additional airway anomalies, determine the revision rate for cleft repair, characterize the time to revision among patients who underwent cleft repair, and assess the functional swallowing outcomes after cleft repair. DESIGN, SETTING, AND PARTICIPANTS: A retrospective study was conducted at a quaternary pediatric center of 81 children diagnosed as having laryngotracheal cleft with or without concomitant airway anomalies who underwent laryngotracheal cleft repair between February 1, 2000, and February 28, 2013. Analysis was conducted from October 1, 2012, through March 30, 2013. INTERVENTIONS: Surgical repair of laryngotracheal cleft. MAIN OUTCOMES AND MEASURES: Surgery-specific success, overall surgical success, and revision rate. We defined surgery-specific success as a repair not requiring revision and overall surgical success as absence of a cleft or TEF at the last operative examination, regardless of the number of revisions required. RESULTS: Of 81 patients with laryngotracheal cleft who underwent surgical repair, 48 (59%) had at least 1 additional airway finding; 24 (30%) had tracheomalacia and 21 (26%) had subglottic stenosis. Seventeen patients required a revision of laryngotracheal cleft repair, with a median time to revision of 8.3 months (interquartile range, 4.3-25.1 months). Six patients required a second revision, with a median interval between revisions of 44.2 months (interquartile range, 28.6-53.6 months). The surgery-specific success rate was 77% (37 of 48) in patients with additional airway anomalies and 82% (27 of 33) in those with laryngotracheal clefts alone. The overall surgical success rate was 92% (44 of 48) in patients with additional airway anomalies and 97% (32 of 33) in those with clefts alone. Fourteen (17%) patients demonstrated swallowing dysfunction postoperatively despite closure of the cleft. CONCLUSIONS AND RELEVANCE: Although additional airway findings were common in our cohort of patients with laryngotracheal clefts, these anomalies did not affect surgery-specific or overall surgical success. The overall surgical success rate for those with and without additional airway anomalies was 92% and 97%, respectively. In view of the fact that cleft breakdown after surgical repair is not uncommon and may occur years after the initial repair, we strongly advocate long-term follow-up. Despite successful closure, a significant percentage of children with laryngotracheal cleft will have persistent swallowing dysfunction.

Swallowing function after laryngeal cleft repair: more than just fixing the cleft.

OBJECTIVES/HYPOTHESIS: To evaluate and describe the swallowing function in children after laryngeal cleft repair. STUDY DESIGN: Ten-year (2002-2012) retrospective chart review. SETTING: Academic tertiary care pediatric otolaryngology practice. METHODS: Records of 60 children who had surgical repair of laryngeal cleft (ages 2 weeks-14 years) and postoperative functional endoscopic evaluation of swallowing or videofluoroscopic swallow studies were examined retrospectively. RESULTS: Twenty-nine children had one postoperative swallow evaluation, 19 children had two, 4 children had three, 5 children had four, and 3 children had five. Median time to the first evaluation was 10.8 weeks (interquartile range [IQR]: 36.5, 231). On the final swallow evaluation, 34 (57%) children demonstrated normal swallowing parameters, 12 (20%) children showed penetration, and 14 (23%) children showed aspiration. Forty-three (72%) children were able to take everything by mouth normally or with minor behavioral modifications, 11 (18%) children required thickened fluids, and six (10%) children were kept nil per os (NPO). Mean improvement on the penetration-aspiration (pen-asp) scale was 2.13. On multivariable analysis, neurodevelopmental issues and gastronomy tube use were associated with the need for NPO status. CONCLUSION: Despite a high rate of surgical success, a substantial minority of children have persistent swallowing dysfunction after laryngeal cleft repair. Swallowing dysfunction after repair is multifactorial and arises from concomitant neurologic, anatomic, or other comorbidities that contribute to oropharyngeal and pharyngeal dysphagia. Based on our results, we recommend a testing schedule for postoperative swallowing evaluations after cleft repair.

High-dose sublesional bevacizumab (avastin) for pediatric recurrent respiratory papillomatosis.

OBJECTIVES: We review and report the use of high-dose bevacizumab for the treatment of recurrent respiratory papillomatosis (RRP) in pediatric patients. METHODS: We included all patients with pediatric-onset RRP who underwent bevacizumab (25 mg/mL) injections by a single practitioner. A series of 5 consecutive subepithelial injections were administered at 4- to 6-week intervals with concomitant 532 nm KTP laser ablation. The lesions were staged according to the Derkay staging system. The outcomes included pretreatment and posttreatment Derkay scores, the time interval between procedures, and voice outcomes. The demographic data extracted included sex, age at diagnosis, and current age. RESULTS: Nine patients were included in this study, with 1 patient lost to follow-up; their median age was 8 years (range, 3 to 21 years). The mean bevacizumab dose was 14.25 mg (range, 5 to 45 mg). There was a median Derkay score of 11.5 (range, 4 to 23) at the time of diagnosis and a median 58% improvement following therapy. All patients demonstrated an increased time interval between injections, for a median improvement of 2.05× (range, 1.6× to 3.25×). CONCLUSIONS: Evidence exists in support of vascular endothelial growth factor as an important factor in the development of RRP. Although some variability in response is demonstrated by this study, high-dose bevacizumab appears to yield promising results for pediatric patients with RRP.

Tracheocutaneous fistula closure in the pediatric population: should secondary closure be the standard of care?

OBJECTIVE: 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. STUDY DESIGN: Historical cohort study. SETTING: Academic tertiary care pediatric otolaryngology practice. Subjects and Methods Two hundred sixteen patients who underwent TCF closure between January 2004 and August 2012. RESULTS: 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). CONCLUSION: 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.

Pediatric tracheal reconstruction using cadaveric homograft.

OBJECTIVE: To examine the indications, risks, and surgical outcomes after tracheal reconstruction using cadaveric homograft in children. DESIGN: Retrospective medical record review. SETTING: Tertiary referral center. PATIENTS: Ten children (4 boys and 6 girls). INTERVENTION: Tracheal reconstruction using cadaveric homograft. MAIN OUTCOME MEASURES: Cause of stenosis, number and type of procedures before homograft reconstruction, severity of preoperative stenosis, surgical approach, homograft length, duration of stenting, number and type of procedures after reconstruction, and rates of decannulation and survival. RESULTS: Ten children (mean [SD] age, 8.4 [5.5] years) underwent 14 tracheal reconstructions using cadaveric homograft. Patients had an average of 7.0 (range, 1-16) procedures before homograft reconstruction, including an average of 2.8 (range, 0-6) major open airway reconstructions. Mean (SD) pretracheoplasty Myer-Cotton grade of stenosis was 3.80 (0.42) (range, 3-4), and all patients were tracheotomy dependent. A cervical approach was used in 12 reconstructions (86%), and 2 (14%) required median sternotomy. Mean (SD) homograft length was 3.9 (1.7) cm (range, 2-8 cm), which was approximately 0.60 times the length of the total recipient trachea. Mean (SD) duration of stenting for all homografts was 0.67 (0.46) years (range, 0.24-1.98 years). The survival rate was 90% after a mean follow-up of 5.47 (1.52) years (range, 3.32-7.55 years). Surviving patients required an average of 7.38 (5.52) procedures (range, 1-19) after homograft transplant, including an average of 1 major open airway reconstruction (range, 0-4). The mean (SD) grade of stenosis after the final homograft placement was 1.89 (1.27) (range, 1-4). Although the operation-specific decannulation rate was only 7% (1 of 14), the overall decannulation rate eventually reached 60%. Statistical bootstrapping methods and a multivariate regression model determined that increasing patient age (odds ratio, 1.21; 95% confidence interval, 1.07-1.36), increasing number of prior procedures (1.26; 1.02-1.57), and increasing homograft length (2.42; 1.60-3.40 [P < .001]) were associated with an increased risk of no decannulation after tracheal homograft reconstruction. CONCLUSIONS: Tracheal reconstruction using cadaveric homograft is an option in children who have undergone multiple airway surgical procedures and present with long-segment stenoses that cannot be bridged using conventional methods. These patients must receive close postoperative follow-up. Subsequent procedures are almost always required before decannulation, and eventual decannulation rates are only 60%. Decannulation rates are lower in older patients who have previously undergone many procedures and require a long tracheal homograft.

Oropharyngeal stenosis: a complication of multilevel, single-stage upper airway surgery in children.

OBJECTIVES: To describe oropharyngeal stenosis (OPS), a potential complication of multilevel, single-stage upper airway surgery involving lingual tonsillectomy in children, and to discuss the manner in which OPS may be managed successfully. DESIGN: Case series with an average follow-up of 12 months. SETTING: Tertiary care children's hospital. PATIENTS: Medical charts were reviewed for 104 patients who underwent lingual tonsillectomy over a 30-month period from January 1, 2007, to June 30, 2009. INTERVENTION: Multilevel, single-stage upper airway surgery, including lingual tonsillectomy. MAIN OUTCOME MEASURE: Development of OPS noted during office or intraoperative examination. RESULTS: Forty-nine of 104 patients underwent multilevel, single-stage upper airway procedures that included lingual tonsillectomy. Four of these 49 patients developed OPS, for a complication rate of 8.2%. Three patients required pharyngoplasty (scar release, debulking of fibrotic tissue, and reorientation of the scar) and triamcinolone injections in the operating room. A fourth patient underwent simple scar release in the operating room. No patient who underwent lingual tonsillectomy alone or in combination with an additional procedure at the same level of the upper airway developed OPS. CONCLUSIONS: Oropharyngeal stenosis is a potential complication of multilevel, single-stage upper airway surgery involving lingual tonsillectomy in children. Although there is pressure to perform multilevel procedures that address each site of upper airway obstruction in 1 sitting, this case series suggests the need for a more conservative, staged approach if lingual tonsillectomy is planned.

Characterization of congenital anomalies in individuals with choanal atresia.

OBJECTIVE: To review a tertiary care pediatric hospital's experience with choanal atresia and stenosis (CA/S) related to associated congenital anomalies (birth defects, including minor abnormalities) and genetic disorders. DESIGN: Retrospective case series. SETTING: Tertiary care pediatric hospital. PATIENTS: Individuals with CA/S. MAIN OUTCOME MEASURES: Identification of congenital anomalies, neurologic abnormalities, and developmental disabilities in individuals with CA/S. RESULTS: One hundred twenty-nine individuals with CA/S were evaluated between July 1, 1997, and July 1, 2007. Choanal atresia and stenosis was an isolated finding in 34 patients (26.4%) and was associated with other anomalies in 95 patients (73.6%). Specific conditions were diagnosed in 66 patients (51.2%); CHARGE (coloboma, heart defect, atresia choanae, retarded growth, genitourinary abnormalities, and ear anomalies) syndrome was the most common diagnosis (33 patients [25.6%]). Numerous conditions were seen, including chromosomal abnormalities, single-gene defects, deformations, and those caused by teratogens. Choanal atresia and stenosis was unilateral in 62 patients (48.1%) and was bilateral in 60 patients (46.5%). Unilateral cases were more likely to be isolated (30 patients [53.2%]). Bilateral cases were more likely to be associated with specific disorders or multiple congenital anomalies (60 patients [98.4%]). There was no difference in laterality among unilateral cases. CONCLUSIONS: Choanal atresia and stenosis is associated with a wide range of disorders. Congenital anomalies, neurologic abnormalities, and developmental disabilities are commonly identified in affected individuals. Bilateral CA/S is more commonly seen in patients in whom specific diagnoses or other congenital anomalies are identified. Unilateral CA/S occurs more frequently in isolated cases. A comprehensive evaluation is recommended in individuals with CA/S to evaluate for other congenital anomalies, neurologic abnormalities, developmental delays, and evidence of a specific underlying disorder.

Management of traumatic tracheobronchial separation in a teenager using a fabricated extra-long endotracheal tube.

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.
