Mal de Débarquement Syndrome in Children: A Case Series.

Currently, mal de débarquement syndrome (MdDS) has been reported only among adults. This case series describes 3 pediatric patients with MdDS. MdDS presentation in children is similar to that of adults, although the frequency of comorbid conditions is greater. Diagnostic delays are common and likely due to under-recognition of MdDS among children.

Management of Periodic Fever, Aphthous Stomatitis, Pharyngitis, Adenitis with Intracapsular Tonsillectomy.

OBJECTIVE: This study aimed to present 2 children clinically diagnosed with periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome and treated with intracapsular tonsillectomy with adenoidectomy (ITA). METHODS: We conducted a retrospective analysis of 2 children who were referred for an otolaryngology consultation between 2019 and 2022 for surgical treatment of PFAPA syndrome. Both patients had symptoms strongly suggestive of PFAPA and were at risk for total tonsillectomy (TT) complications. ITA was performed using a microdebrider. Both patients were followed up postoperatively to assess for symptomatic resolution and complications. RESULTS: Two children exhibited recurrent febrile episodes prior to ITA. The procedure was efficacious in both patients, with neither experiencing postoperative complications or recurring PFAPA symptoms for over 1 year after surgery. CONCLUSION: Our study reported on the use of ITA as a surgical treatment option for PFAPA. We showed that ITA eliminated febrile attacks and was safely performed without postoperative complications in 2 pediatric patients after 1-year follow-up. Future studies involving larger cohorts of PFAPA patients and lengthier follow-ups will need to be conducted to further evaluate ITA as a surgical option. Laryngoscope, 134:1967-1969, 2024.

Relationship Between National Residency Matching Program (NRMP) Rank Order and Otolaryngology Residency Performance.

Objective: The process of resident recruitment is costly, and our surgical residency program expends significant time on the resident selection process while balancing general duties and responsibilities. The aim of our study was to explore the relationship between otolaryngology-head and surgery (OHNS) residents' National Residency Matching Program (NRMP) rank-list position at our institution and their subsequent residency performance. Study Design: Retrospective cohort study. Setting: Single site institution. Methods: We retrospectively reviewed 7 consecutive resident classes (2011-2017) at a single tertiary OHNS residency program. We reviewed each resident's absolute rank order in the NRMP matches. Measures of residency performance included overall faculty evaluation during postgraduate year 5 (PGY5), annual in-service examination scores (scaled score), and the number of manuscripts published in peer-reviewed journals. Correlations between NRMP rank order and subsequent residency performance were assessed using Spearman's rho correlation coefficients (ρ). Results: Twenty-eight residents entered residency training between 2011 and 2017. The average rank position of the trainees during this study was 9.7 (range: 1-22). We found no significant correlation between rank order and faculty evaluation during PGY5 (ρ = 0.097, P = .625) or number of publications (ρ = -0.256, P = .189). Additionally, when assessing the association between rank order and annual Otolaryngology Training Examination-scaled scores, no statistically significant relationship was found between the 2 (P > .05). Conclusion: Our results showed that there were no significant correlations between OHNS rank order and various measures of success in residency training, which aligns with existing literature. Further investigation of this relationship should be conducted to ensure the applicability of our findings.

A New Approach for Diagnosis and Surveillance of Infantile Subglottic Hemangioma in the Era of Propranolol Use: A Case Series.

OBJECTIVE: To report our institutional experience in diagnosing and surveilling patients with infantile subglottic hemangioma (SGH) using in-office flexible fiberoptic laryngoscopy (FFL) with video technology, without requiring operative endoscopy in the era of propranolol use. METHODS: A retrospective case series was conducted on 4 children diagnosed with SGH between 2016 and 2022 at our institution. RESULTS: Awake FFL with video technology provided adequate visualization of SGH lesions for diagnosis, without any complications. Serial examinations of the airway were performed in the outpatient setting and each SGH gradually regressed, with marked improvement in respiratory symptoms within 48 hours of oral propranolol initiation. CONCLUSION: Our findings showed that in select patients, FFL with video technology can successfully identify SGH lesions without general anesthesia exposure. FFL may be used as a low-risk screening tool for propranolol therapy initiation in some patients, but operative endoscopy should remain the gold standard procedure for others. By utilizing FFL in this manner, it is possible to diagnose SGH lesions and start propranolol therapy without exposing all patients to the risks of operative endoscopy.

Off-Label Use of Ciprofloxacin/Dexamethasone Drops in the Pediatric Upper Airway: Case Presentation and Review of Adverse Effects.

OBJECTIVE: This report describes a new observation of hyperglycemia in a child with Type 1 diabetes after off-label use of otic ciprofloxacin/dexamethasone drops in the nasal passage and reviews previous reports of adverse endocrine effects from intranasal corticosteroids in pediatric patients. METHODS: We describe the clinical case and conducted a literature review of MEDLINE (PubMed) and EMBASE. RESULTS: A 9-month-old female with a history of Type 1 diabetes who underwent unilateral choanal atresia repair was started on 1 week of ciprofloxacin 0.3%/dexamethasone 0.1% otic drops twice a day for choanal obstruction with granulation tissue. While the patient's airway patency improved, average daily blood glucose increases by 40 to 50 points were noted on the patient's continuous glucose monitor. The hyperglycemia resolved within 2 days after switching to mometasone furoate 0.05% spray. We also review 21 pediatric otolaryngology cases of iatrogenic Cushing's syndrome associated with on- and off-label use of topical steroid suspensions in the airway. Patients ranged from 3 months to 16 years in age and used doses of 50 µg/day to 2 mg/day. CONCLUSION: This is the first reported pediatric case of increased blood glucose levels associated with intranasal steroid suspensions, to the best of our knowledge. Counseling families on precise dose administration and potential endocrine disturbances is critical when prescribing these medications for off-label use in infants and small children, particularly among patients with underlying endocrine disorders such as diabetes.

Synchronous disease onset and flares in siblings with PFAPA.

BACKGROUND: Periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) is a clinical syndrome of unclear etiology. PFAPA has generally been considered a non-hereditary fever syndrome; however, this has been called into question with recent reports of family clustering. Few reports have been published describing siblings with PFAPA. To our knowledge, this is the first report of siblings with near simultaneous onset of disease followed by synchronous disease flares. CASE PRESENTATION: We describe the case of near simultaneous onset of periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis in siblings followed by synchronous disease flares of clear frequency and nearly identical character. Flares were characterized predominantly by fever, aphthous ulceration, cervical lymphadenitis, and the absence of infection. The fever episodes demonstrated a robust response to glucocorticoids and recurred in the same staggered manner every four weeks, with complete absence of symptoms and normal growth and development between episodes. Nine months after onset, the older sibling, a 5-year-old female, underwent tonsillectomy resulting in dramatic resolution of episodes. At the same time, her 2-year-old sister experienced resolution of her fever episodes, though she did not undergo tonsillectomy herself. CONCLUSION: This is an unusual case of simultaneous onset PFAPA followed by synchronous disease flares. PFAPA is an uncommon clinical syndrome, and it is rarely diagnosed in siblings. The etiology of PFAPA remains unclear. Though the disease is classically considered sporadic, there is a growing body of evidence to suggest that PFAPA may be heritable.

Association between superior labial frenum and maxillary midline diastema - a systematic review.

BACKGROUND: Pediatric otolaryngologists have seen an increased focus on upper lip frenum as a possible culprit for feeding difficulties and the development of maxillary midline diastema (MMD). This increase may be encouraged by parents' exposure to medical advice over the internet about breastfeeding and potential long-term aesthetic concerns for their children. Subsequently, there has been increased pressure on pediatric otolaryngologists to perform superior labial frenectomies. There has been a reported 10-fold increase in frenectomies since the year 2000. However, there is no consensus within the literature regarding the benefit of superior labial frenectomy in preventing midline diastema. OBJECTIVE: To provide physicians and parents with the most updated information by systematically reviewing the available literature for the association between superior labial frenum and midline diastema. METHODS: A literature search was performed in MEDLINE (PubMed), EMBASE, Web of Science, the Cochrane Library and Dental and Oral Sciences Source (DOSS). Using the Covidence platform, a systematic review was conducted. The initial 314 articles identified underwent systematic review and 11 studies were included in the final review. RESULTS/DISCUSSION: Available data, primarily from the dental literature, showed that two subtypes of frenum: papillary and papillary penetrating frenum, are associated with maxillary midline diastema. Superior labial frenectomy should be delayed until permanent lateral incisors have erupted, as this can spontaneously close the physiological MMD. Current literature recommends against frenectomy before addressing the diastema with orthodontics, which helps to prevent diastema relapse. It is also imperative to rule out other odontogenic and oral cavity causes of diastema, such as thumb sucking, dental agenesis, and other causes. Online information may not always be fully representative and should be interpreted in the full context of the patient's medical history before referral for surgical intervention.

Yield of preoperative findings in pediatric airway foreign bodies - A meta-analysis.

IMPORTANCE: Foreign body (FB) aspiration into the airway is a significant cause of pediatric morbidity and mortality, yet the clinical presentation is diverse and dynamic. There are conflicting recommendations which pre-procedural findings support performing a bronchoscopy, the gold standard for diagnosis and removal of FBs, however a procedure that entails general anesthesia and possible risks. OBJECTIVE: Decision whether to proceed to a bronchoscopy may be challenging. Our goal was to enhance decision-making by analyzing the diagnostic values of the different pre-procedural findings in this setting. DATA SOURCES: A comprehensive search was performed in PUBMED, EMBASE and Cochrane Review databases to find studies from the last 19 years that reported pre-procedural history, physical examination and radiological findings in patients who had bronchoscopies. STUDY SELECTION: Studies were included of pediatric populations if they contained bronchoscopy results (positive and negative for foreign body) with a breakdown according to pre-intervention findings. DATA EXTRACTION AND SYNTHESIS: Titles and abstracts retrieved from our search were screened. Thereafter, full-texts were carefully reviewed and selected for inclusion if the aforementioned criteria were met. PRISMA guidelines for systematic review and meta-analyses were followed. MAIN OUTCOME(S) AND MEASURE(S): Cumulative weighted prevalence, sensitivity, specificity, positive and negative predictive values of each pre-procedural finding were calculated, as well as for the "classic triad" (history of an acute event, wheezing, and unilateral decreased breath sounds). Calculation for other combinations of findings, or optimally, constructing a weighted score based on all the findings for each specific patient were not possible to perform, as the specific data breakdown is rarely reported. RESULTS: Fifteen studies met inclusion criteria, totaling 5606 patients who underwent bronchoscopies. All studies but one were single center based and all except one were retrospective. No single finding has both positive and negative predictive values over 50%. The "classic triad" has 90% specificity, however only 35% sensitivity. CONCLUSIONS: The data is very heterogeneous with regard to pre-procedural findings and how best to guide treatment according to them. This meta-analysis provides cumulative weighted metrics for each finding, to optimize decision-making for the individual patient. Future reporting of data should be enhanced, so that combinations of findings for a specific patient can be used to optimize management. LEVEL OF EVIDENCE: 4.

Reduction in surgical innovation, 1988 to 2006.

OBJECTIVE: We hypothesize that increasing regulation of human subject research has reduced the number of published reports of surgical innovation in otolaryngology. STUDY DESIGN: A systematic review of a predetermined subset of otolaryngology literature. METHODS: We randomly selected half of the articles published in 1988 and 2006 in three prominent journals. After identifying information was concealed, abstracts were classified independently by two authors into three groups: innovation, modification, or neither. Disagreements were resolved by a third author who read the entire article. Proportions were compared with chi(2) analysis. RESULTS: The proportion of articles classified as innovation or modification decreased significantly from 67 of 367 (18.3%) in 1988 to 59 of 548 (10.8%) in 2006 (P = 0.001). The elimination of radiology and pathology quiz cases yielded similar results: 11.1 percent vs 18.9 percent, P = 0.001. Innovation or modification in animal model research also decreased (0.9% vs 3.8%, P = 0.003). Overall, only 4 articles were actually classified as true innovation. CONCLUSIONS: The frequency of true innovation was low in both years, but articles that described surgical modifications decreased significantly over this 18-year period. One reason may be increased administrative barriers for clinical research approval. Although our analysis cannot determine cause and effect, it is an important finding that deserves further study.

Minimally invasive techniques in laryngotracheal reconstruction.

The treatment of laryngotracheal stenosis has evolved over the past several decades. Advances in technology, equipment and medication have increased our ability to treat some airway stenosis in a minimally invasive manner, and at times by an endoscopic method. With improved precision, our results with postoperative voice and swallowing should improve.

Scoping review: Awareness of neurotoxicity from anesthesia in children in otolaryngology literature.

OBJECTIVE: Review otolaryngology literature for awareness of neurotoxicity from general anesthesia in children. Recently, there has been increasing focus in anesthesia literature on the long-term effects of general anesthesia on neurodevelopment. Multiple animal models have demonstrated evidence of neurotoxicity from both inhalational and intravenous anesthetics. Cohort studies also have revealed modestly increased risk of adverse neurodevelopmental outcomes in children exposed to a single episode of general anesthesia prior to 3 to 4 years of age, with stronger evidence for multiple exposures in this age range. Otolaryngologists may subject children to general anesthesia via procedures or tests, including computed tomography, magnetic resonance imaging, and auditory brainstem response. DATA SOURCES: PubMed, Embase, Scopus, and Web of Science Review. METHODS: A scoping review using the above databases was performed limited to January 2005 through December 2015. Articles were screened and reviewed based on predefined inclusion and exclusion criteria. RESULTS: Initial search generated 3,909 articles. After 72 full text articles were reviewed, only seven articles mentioned neurotoxicity as a risk of general anesthesia in pediatric patients. CONCLUSION: Despite the high volume of pediatric otolaryngologic procedures performed annually, there remains limited awareness in our literature discussing neurotoxicity as an outcome. Prospective data from anesthesia literature is still pending; therefore, specific recommendations cannot be made at this time. Otolaryngologists should be aware of the concerns and work toward defining elective procedures, combining surgical procedures with other procedures or imaging, and reassessing the timing and frequency of various interventions under general anesthesia in young children.

Recurrent periorbital cellulitis: an unusual clinical entity.

OBJECTIVES: To discuss the cause and management of recurrent periorbital cellulitis (RPOC). STUDY DESIGN: Retrospective case series and review of literature. MATERIALS AND METHODS: In the past 11 years, we have treated 6 patients for recurrent periorbital cellulitis (RPOC). Inclusion criteria were a minimum of 3 episodes of periorbital cellulitis (POC) within a 1-year period, with interval convalescence lasting at least 1 month. All patients were followed for at least 1 year after resolution. RESULTS: The causes of RPOC were as follows: (1) 2 patients developed RPOC attributed to environmental allergies; (2) 1 was diagnosed with underlying recurrent sinusitis resistant to medical management with resolution attained through surgery; (3) 1 patient with vesicular RPOC was diagnosed with herpetic RPOC and treated medically with antiviral therapy; (4) 1 patient had allergic contact dermatitis from cosmetic make-up use; and (5) 1 patient was suspected of malingering via repeat subcutaneous self-injection of an irritant. CONCLUSIONS: Although periorbital cellulitis is a commonly encountered and treatable condition, recurrent periorbital cellulitis is rare and may be challenging to manage. In our experience, the causes of recurrence varied, but resolution was achieved by identifying the underlying cause through continuous clinical reassessment and by appropriate medical or surgical management. EBM RATING: C-4.

Evaluation and management of pediatric nasal obstruction: A survey of practice patterns.

BACKGROUND: Inferior turbinate (IT) hypertrophy and adenoid hypertrophy are both causes of pediatric nasal obstruction. OBJECTIVE: The purpose of this survey was to study nasal obstruction evaluation and management among pediatric otolaryngologists with respect to IT and adenoid hypertrophy. METHODS: A questionnaire with embedded clinical videos was sent electronically to American Society of Pediatric Otolaryngology members. RESULTS: A total of 435 questionnaires were sent, and 75 were completed. Respondents were presented with scenarios that involved a 7-year-old child with nasal obstruction unresponsive to medical therapy, and the respondents were asked to choose a surgical plan, either IT reduction, adenoidectomy, or combined IT reduction and adenoidectomy. Three questions described the extent of IT and adenoid obstruction in text form, although three questions included a video of the child's nasal endoscopy. In questions with perceived or stated IT hypertrophy, the respondents chose to perform IT reduction significantly more frequently when the perceived or stated adenoid hypertrophy was less severe (p < 0.0001 for video and p = 0.039 for written questions). CONCLUSION: The decision to perform IT reduction in children is inversely related to the extent of adenoid hypertrophy. Future studies on pediatric IT surgery should include objective descriptions of the IT and adenoid in study subjects.

Safety and efficacy of powered intracapsular tonsillectomy in children: a multi-center retrospective case series.

OBJECTIVE: To determine the efficacy of powered intracapsular tonsillectomy (PIT, e.g. regrowth rate) in children who underwent PIT at three different institutions. We also wanted to determine if the trend to greater safety through reduced bleeding and re-admission for dehydration, noted in our initial reports, would become statistically significant in a larger sample. STUDY DESIGN AND SETTING: Multi-center retrospective case series. PATIENTS AND METHODS: We retrospectively reviewed all charts' of children who underwent PIT at three different institutions: the Children's Hospital at the Cleveland Clinic, Alfred I. DuPont Hospital for Children, and the New York Otolaryngology Institute. For comparison, we reviewed the outpatient and inpatient records of all children who underwent conventional tonsillectomy performed by the same surgeons at the Children's Hospital at the Cleveland Clinic and Alfred I. DuPont Hospital for Children during the same period. No comparison group was available for the New York Otolaryngology Institute group. Three outcome measures were recorded: regrowth, bleeding and re-admission for dehydration rates. All statistical analyses were performed using SAS, and P < 0.05 was considered statistically significant. RESULTS: We identified 870 children that underwent PIT at three different institutions. In addition, 1121 children underwent conventional tonsillectomy at two of the three institutions. The mean follow-up for the PIT group was 1.2 years (range, 0.1-2.6 years) and 1.5 years (range, 0.1-3.0 years) for the conventional tonsillectomy group. The incidence of and 95% CI for the outcome measures were as follows regrowth 0.5% (0%, 1.4%), delayed post-operative bleeding 0.7% (0%, 1.9%), re-admission for dehydration 1.3% (0.05%, 2.6%), and overall major complications 0.46% (0.009%, 0.9%). When comparing conventional tonsillectomy to PIT, the bleeding rate, re-admission for dehydration, and the overall incidence of major complications were significantly lower in the PIT group (P = 0.001, P = 0.002, and P < 0.001, respectively). CONCLUSION: PIT is a safe and effective technique in the management of obstructive sleep disordered breathing in children. PIT has the advantages of decreased pain, dehydration and post-operative bleeding, and with a mean follow-up of 1.2 years, a low incidence of tonsillar regrowth thus far.

Familial congenital bilateral vocal fold paralysis: a novel gene translocation.

OBJECTIVES: True vocal fold (TVF) paralysis is a common cause of neonatal stridor and airway obstruction, though bilateral TVF paralysis is seen less frequently. Rare cases of familial congenital TVF paralysis have been described with implied genetic origin, but few genetic abnormalities have been discovered to date. The purpose of this study is to describe a novel chromosomal translocation responsible for congenital bilateral TVF immobility. METHODS: The charts of three patients were retrospectively reviewed: a 35 year-old woman and her two children. The mother had bilateral TVF paralysis at birth requiring tracheotomy. Her oldest child had a similar presentation at birth and also required tracheotomy, while the younger child had laryngomalacia without TVF paralysis. Standard karyotype analysis was done using samples from all three patients and the parents of the mother, to assess whether a chromosomal abnormality was responsible. RESULTS: Karyotype analysis revealed the same balanced translocation between chromosomes 5 and 14, t(5;14) (p15.3, q11.2) in the mother and her two daughters. No other genetic abnormalities were identified. Neither maternal grandparent had the translocation, which appeared to be a spontaneous mutation in the mother with autosomal dominant inheritance and variable penetrance. CONCLUSIONS: A novel chromosomal translocation was identified that appears to be responsible for familial congenital bilateral TVF paralysis. While there are other reports of genetic abnormalities responsible for this condition, we believe this is the first describing this particular translocation.

Cephalosporin use in penicillin-allergic patients: a survey of otolaryngologists and literature review.

OBJECTIVES/HYPOTHESIS: This study investigated the differences between the standard guidelines and the practice patterns of otolaryngologists in managing "penicillin-allergic" patients. A major goal was to identify factors influencing an otolaryngologist's choice of antibiotic. STUDY DESIGN: Cross-sectional survey. METHODS: Four hundred seventy members of the American Society of Pediatric Otolaryngologists (ASPO) and 150 general otolaryngologists from the Florida Society of Otolaryngology (FSO) were surveyed. RESULTS: Ninety-six ASPO members (20.4%) and 22 members of FSO (14.6%) responded. When asked about the management of a pediatric patient with acute otitis media and a history of a nonsevere immunoglobulin E (IgE)-mediated amoxicillin allergy, 54% of ASPO respondents indicated they would initiate guideline-recommended cefdinir, whereas only 27% of FSO respondents chose cefdinir (P = .02). Otolaryngologists who are fellowship trained in pediatrics or have pediatric-focused practices were significantly more likely to prescribe cefdinir. Overall, 57% of respondents indicated that they were familiar with the literature regarding the cross-reactivity of ß-lactams, but only 25% of respondents felt that they could easily differentiate a potentially life-threatening IgE-mediated allergy from a non-IgE-mediated drug intolerance. CONCLUSIONS: The data show differences between the current recommendations and the behavior of otolaryngologists. Pediatric otolaryngologists were more familiar with the guideline-recommended therapy, likely from their frequent exposure to patients requiring a ß-lactam. Nevertheless, most otolaryngologists could benefit from increased awareness of the current literature. Patients may be receiving less than optimal medication management due to a misidentification of those at risk of life- threatening allergic cross-reactions. LEVEL OF EVIDENCE: NA

Complications of microdebrider-assisted powered intracapsular tonsillectomy and adenoidectomy.

OBJECTIVES: To study complications of powered intracapsular tonsillectomy and adenoidectomy (PITA) in pediatric patients with obstructive sleep apnea (OSA). STUDY DESIGN: Retrospective chart review and long-term follow-up in office or by telephone interview. METHODS: We studied 278 patients who underwent PITA between September 2000 and October 2002. Outcome measures were postoperative bleeding, velopharyngeal insufficiency, need for hospital readmission, tonsil regrowth, and return of snoring or sleep apnea symptoms. RESULTS: All 278 children treated by PITA had immediate resolution of symptoms of OSA. Complications were noted in 11 patients (3.9%). Nine patients (3.2%) experienced tonsil regrowth with snoring, two of whom evolved to a return of OSA that was definitively managed by means of a complete tonsillectomy. Two patients (0.7%) had self-limited bleeding. None of the patients developed persistent velopharyngeal insufficiency or required hospital readmission. CONCLUSIONS: Microdebrider-assisted PITA is a safe and effective alternative for children otherwise treated with traditional tonsillectomy for symptoms of OSA due to adenotonsillar hypertrophy. This series suggests a 3.9% overall rate of complications, with the most common noted as tonsillar regrowth without recurrence of OSA. Prospective trials with longer follow-up may define higher complication rates.

Ambulatory powered intracapsular tonsillectomy and adenoidectomy in children younger than 3 years.

OBJECTIVES: (1) To assess the safety and efficacy of outpatient intracapsular tonsillectomy, which has been recently described as a less invasive means of treating obstructive tonsillar hypertrophy, in children younger than 3 years; and (2) to challenge the standard dictum that children younger than 3 years should be admitted to the hospital after tonsil and adenoid surgery. DESIGN: Retrospective cohort study via medical chart review and telephone interview. SETTING: Pediatric otolaryngology group practice with academic affiliation. Patients Children with symptomatic tonsillar and adenoid hypertrophy (n = 226) who underwent microdebrider-assisted intracapsular tonsillectomy between September 1, 2000, and October 1, 2002. METHODS: Comparison of study group (children <3 years old, n = 38; mean age, 30.3 months; 20 boys and 18 girls) with control group (children > or =3 years, n = 188), measuring pain, oral intake, analgesic requirements, complications, need for readmission, and relief of symptoms. RESULTS: There were no statistically significant differences in pain, oral intake, or analgesic requirements. All children, regardless of age, were discharged home within 4 hours of surgery. No child in either group required readmission, and there were no complications related to the time of discharge. Younger children experience equivalent symptomatic improvement. CONCLUSION: Children younger than 3 years may undergo intracapsular tonsillectomy as outpatients without sacrificing safety or efficacy.

Topical mitomycin as an adjunct to choanal atresia repair.

OBJECTIVE: To evaluate the use of topical mitomycin in choanal atresia repair to reduce the development of granulation tissue and cicatrix. DESIGN AND SETTING: Retrospective case series in 2 tertiary care centers. PATIENTS: Twenty patients with either unilateral or bilateral congenital choanal atresia underwent repair using the transnasal endoscopic approach, the transpalatal approach, or both. INTERVENTIONS: The surgeons favor the use of the endoscopic transnasal drillout technique for all unilateral cases of choanal atresia and for selected bilateral cases. We describe our experience and treatment paradigm for these 20 patients (15 with unilateral atresia, 5 with bilateral atresia). Topical application of mitomycin was used, and in some cases postoperative stenting, for a period of 1 to 2 weeks. In 8 cases, a second application of mitomycin was used. Follow-up ranged from 3 months to 2 years (mean, 9 months). OUTCOME MEASURE: The patency of the choanae without respiratory distress or nasal drainage, as assessed by endoscopic evaluation, determined a successful repair. RESULTS: Of the 20 patients, 17 retained patent airways. Three patients experienced improvement from a total atresia to a narrowed, stenotic choana. CONCLUSIONS: The use of mitomycin as an adjunct to the surgical repair of choanal atresia may offer improved patency with a decreased need for stenting, dilatations, and revision surgery. Newer endoscopic techniques with powered instrumentation further enhance the safety and efficacy in the repair of choanal atresia.

Endoscopically placed nitinol stents for pediatric tracheal obstruction.

OBJECTIVE: To provide preliminary clinical data regarding endoscopically placed nitinol stents for children with tracheal obstruction as a temporizing measure to allow for trach tube decannulation while awaiting growth to allow for tracheal resection. METHODS: This case series describes the experiences of two children (ages 5 and 15) who were dependent upon tracheotomy because of acquired tracheal obstruction. Both patients had combined tracheomalacia and tracheal stenosis. After failing tracheoplasty with rib graft augmentation both patients suffered from extensive tracheal disease, which was too long to allow for immediate tracheal resection. INTERVENTION: Endoscopic placement of nitinol stents in the obstructed tracheal segment using fluoroscopic guidance. All tracheotomy tubes were removed immediately after successful stent deployment with the patient still under general anesthesia. RESULTS: Four stents were placed in total. The first patient's initial stent was too narrow and was, therefore, removed and replaced at a later date with a larger diameter stent. The second patient experienced distal migration of his initial stent requiring stent removal and replacement at a later date. Both patients remain successfully decannulated (follow-up, 25 and 26 months) and are currently living more normal lives as they grow and await tracheal resection. CONCLUSION: Preliminary use of nitinol stents for pediatric tracheal obstruction has enabled successful decannulation in two children with complicated airways. Our results with this series of patients suggest that nitinol stents can be safely used in children as a temporizing measure until tracheal resection can be safely performed. With this approach children can live free from the hassles of trach care, social isolation and peer ridicule. Limited pediatric experience exists in the literature about nitinol stents. Thus, our experience with stent selection and placement will help others avoid problems encountered in this initial series.
