National Trends of Pediatric Aspirated/Ingested Foreign Bodies.

Foreign body (FB) aspiration/ingestion in children represents a major cause of hospital admission and mortality. Evaluating risk factors and identifying trends in specific FB products could improve targeted health literacy and policy changes. A cross-sectional study querying emergency department patients less than 18 years old with a diagnosis of aspirated/ingested FB was conducted using the National Electronic Injury Surveillance System database between 2010 and 2020. Incidence rates per 100 000 people-year were calculated and multivariate analyses were performed to identify risk factors for hospital admission and mortality. There has been a significantly decreasing rate of aspirated (-23.6%; P = .013) but not ingested FB (-9.4%; P = .066) within the study period. Within pediatric aspirated FB, black compared with white patients had decreased odds of same hospital admission (odds ratio [OR]: 0.8), but increased odds of transfer admission (OR: 1.6) and mortality (OR: 9.2) (all, P < .001).

Fulminant Retropharyngeal Edema Associated with SARS-COV-2 (+) Diagnosis in an Adult.

SARS-COV-2 can cause retropharyngeal edema for which literature on optimal management is sparse. Prompt identification and treatment of the condition is vital to successful recovery. This report presents such a case and offers support for conservative management in treatment of retropharyngeal edema.

Outcomes and Management of Infants Who Refer Newborn Hearing Screening.

OBJECTIVES: With the implementation of Universal Newborn Hearing Screening, early diagnosis and referral has been expedited. Many patients who refer screening pass subsequent testing with otoacoustic emissions (OAE) or auditory brainstem response (ABR). The objective of our study was to identify the incidence and etiology of hearing loss in infants who refer initial testing in an urban, tertiary care pediatric otolaryngology practice. METHODS: We performed a chart review of infants who were evaluated after referring newborn hearing screening from 2017 to 2021. Data collected included birth history, hospital screening results, subsequent audiology and otolaryngology visit findings, final hearing diagnoses, interventions, and outcomes. RESULTS: Of the 450 patients, 83.8% (n = 377) had normal hearing bilaterally after repeat testing (OAE and/or ABR). Thirty five patients were diagnosed with otitis media with effusion (OME) (7.8%) and 17 patients (3.8%) were diagnosed with sensorineural hearing loss. Twenty seven patients (6.0%) were diagnosed with obstructing cerumen/vernix, many times in addition to another diagnosis. Of the 17 patients with sensorineural hearing loss, 2 had genetic syndromes and 2 had congenital cytomegalovirus. Sensorineural hearing loss was significantly associated with the presence of a deafness syndrome (P = .004) and in-utero infections (P = .04). About 11 (2.4%) underwent myringotomy with tube placement, 5 (1.1%) were fitted with hearing aids, 2 (0.4%) were referred for hearing aids, 4 (0.9%) had both myringotomy with tube placement and hearing aids, 1 child had a soft band/Bone Anchored Hearing Aid (BAHA) (0.2%), and 1 child (0.2%) had a cochlear implant. CONCLUSION: Our incidence of sensorineural hearing loss was 3.8% (95% CI 2.0, 5.5), compared to rates of 0.44 to 68% in the published literature. Most patients had normal hearing, usually identified after only 1 repeat test. OME requiring myringotomy tube insertion was the most common pathology requiring intervention. Close observation for resolution and intervention, if warranted, is critical to prevent sequelae.

Outcomes of in-office versus operating room insertion of tympanostomy tubes in children.

OBJECTIVE: Tympanostomy tube insertion in children is commonly performed under general anesthesia, but there has been increasing interest in office-based alternatives. Although initial research comparing in-office versus operating room (OR) insertion of tubes looks promising, there are scant data available on long-term outcomes. The objective of this study is to compare long-term outcomes of tympanostomy tubes placed in-office versus the OR, with emphasis on the duration of tube function. METHODS: We reviewed electronic medical records in an academic pediatric otolaryngology practice of children under age 13 years who had tubes placed in-office or the OR between 2010 and 2021. Differences in time to unilateral and bilateral tube occlusion/extrusion were compared by Kaplan-Meier survival analysis with log rank comparison. Cox regression modeling was performed to identify predictors of tube occlusion/extrusion. RESULTS: 817 children were included (473 office tubes, 344 OR tubes). Tube placement was equally successful for both groups (98.3% for office and 98.9% for OR). Comparison of Kaplan-Meier plots for time to unilateral and bilateral tube occlusion/extrusion by location showed no significant difference (P = .842 for unilateral and P = .714 for bilateral). However, regression analysis indicated a strong interaction of location with operator status (resident vs attending). Median time to unilateral occlusion/extrusion and bilateral occlusion/extrusion was shorter for OR residents compared to OR attendings (15.0 vs 19.5 months, P = .002, and 22.1 vs 32.0 months, P = .030, respectively). There was no difference in the time to unilateral or bilateral tube occlusion/extrusion between the office attending and OR attending groups (16.8 vs 19.5 months, P = .057 for unilateral, and 23.0 vs 32.0 months, P = .320 for bilateral). There was no significant difference between groups in the need for tube removal, repeat tubes, tube medialization, or post-extrusion tympanic membrane perforation. CONCLUSION: The comparable long-term outcomes found for tubes inserted in-office versus the OR, including time to occlusion/extrusion, suggest that both settings are acceptable for the procedure, with choice based primarily on parental preference, clinician experience, and shared decision making with families.

Impact of Adenotonsillectomy on Homework Performance in Children With Obstructive Sleep-Disordered Breathing.

OBJECTIVE: As a first line treatment for pediatric obstructive sleep-disordered breathing (SDB), adenotonsillectomy (AT) has been shown to confer physiologic and neurocognitive benefits to a child. However, there is a scarcity of data on how homework performance is affected postoperatively. Our objective was to evaluate the impact of AT on homework performance in children with SDB. METHODS: Children in grades 1 to 8 undergoing AT for SDB based on clinical criteria with or without preoperative polysomnography along with a control group of children undergoing surgery unrelated to the treatment of SDB were recruited. The primary outcome of interest was the differential change in homework performance between the study group and control at follow-up as measured by the validated Homework Performance Questionnaire (HPQ-P). Adjustments were made for demographics and Pediatric Sleep Questionnaire (PSQ) scores. RESULTS: 116 AT and 47 control subjects were recruited, and follow-up data was obtained in 99 AT and 35 control subjects. There were no significant differences between the general (total) HPQ-P scores and subscale scores between the AT and control subjects at entry and there were no significant differences in the change scores (follow-up minus initial scores) between the groups. Regression modeling also demonstrated that there were no group (AT vs control) by time interactions that predicted differential improvements in the HPQ-P (P > .10 for each model) although initial PSQ score was a significant predictor of lower HPQ-P scores for all models. CONCLUSIONS: Children with SDB experienced improvement in HPQ-P scores postoperatively, but the degree of change was not significant when compared to controls. Further studies incorporating additional educational metrics are encouraged to assess the true scholastic impact of AT in children with SDB.

Postoperative respiratory complications after adenotonsillectomy in children with obstructive sleep apnea.

OBJECTIVE: Children with obstructive sleep apnea are considered high risk for postoperative respiratory complications, but opinions differ regarding the polysomnography (PSG) criteria that suggest the need for postoperative admission. Our objective was to determine if otherwise healthy children age ≥3 years with an apnea-hypopnea index (AHI) < 24 on overnight PSG can be safely discharged on the same day of surgery. METHODS: Case series with chart review of children age <18 years with positive PSG (AHI > 2) who underwent adenotonsillectomy (T&A) between January 2013 and August 2019. Data collected included patient demographics, medical history, comorbidities, PSG results, operative details, length of stay, intraoperative and postoperative respiratory complications and management. Potential predictors of respiratory complications were evaluated using chi-square/Fisher's exact test and 2-tailed unpaired t tests with the Bonferroni adjustment for multiple comparison artifact. The percentages of healthy children age ≥3 years who were discharged on the day of surgery at various PSG cutoffs were calculated. RESULTS: Of the 560 children, mean (SD) age was 6.4 (3.7) years, 318 (56.8%) were male, 438 (78.2%) were African American, 243 (43.4%) were obese, 16 (2.9%) had Down Syndrome and 12 (2.1%) had sickle cell disease. Median (range) AHI was 12.3 (2-145). Fifteen children (2.7% [95% CI 1.3, 4.0]) had an intraoperative or postoperative respiratory complication. Minor complications including mild desaturation, stridor, croupy cough, and laryngospasm occurred in 9 patients and did not prolong the planned ambulatory or hospital stay. Of the 6 children with more severe complications including prolonged desaturation, tachypnea, atelectasis, intercostal retraction and obstructive apnea requiring continuous positive airway pressure, all were planned admissions based on age, severe sleep study indices (AHI ≥ 24 or oxygen saturation nadir < 80%) or underlying medical condition. Of the 165 children age ≥3 without medical comorbidities known to be predictive of postoperative complications with an AHI ≥10 but <24, 113 (68.5%) were discharged home on the same day of surgery without additional respiratory sequelae. CONCLUSIONS: This study demonstrates a low risk of respiratory complications after T&A. Otherwise healthy children age ≥3 years with AHI <24 may be considered for ambulatory discharge.

Post-tonsillectomy hemorrhage control with nebulized tranexamic acid: A retrospective cohort study.

OBJECTIVE: Evaluate nebulized tranexamic acid (TXA) as a treatment to reduce the need for an operation to control a post-tonsillectomy hemorrhage (PTH). METHODS: Based on a successful case report of a child treated with nebulized TXA for PTH in 2018, our institution began to treat PTH patients with three doses of nebulized TXA. To evaluate the outcomes of this non-invasive management, we conducted a three-year retrospective cohort study of children presenting with PTH from 2016 to 2019. Demographics, insurance, and laboratory information were collected from all pediatric tonsillectomies with and without adenoidectomy performed during the study period. Tonsillar fossae observations of bleeding and clot were documented before and after receiving TXA. RESULTS: The incidence of pediatric PTH at our institution during the study period was 5.4%. Fourteen out of 58 PTH patients received nebulized TXA. Receiving nebulized TXA had no adverse events and over 60% showed resolution of bleeding on exam. Receiving nebulized TXA compared to routine care decreased the need for an operation to restore hemostasis by 44%, p < 0.005. There was no significant difference in age, gender, body mass index, hemoglobin, platelet count, trainee presence, or Medicaid status between the children that received TXA and those that did not. CONCLUSION: Treatment of PTH with nebulized TXA may be a safe first-line therapy to decrease the need for operative control of bleeding. This data suggests that a large clinical trial is needed to determine the efficacy of nebulized TXA to mitigate this common and potentially fatal post-operative complication. LEVEL OF EVIDENCE: 4.

Management and Outcomes of Button Batteries in the Aerodigestive Tract: A Multi-institutional Study.

OBJECTIVES/HYPOTHESIS: To describe the clinical presentation, management, and complications associated with button battery impaction in the aerodigestive tract in children. STUDY DESIGN: Retrospective case series. METHODS: This multi-institutional study, endorsed by the American Society of Pediatric Otolaryngology research consortium, is a retrospective medical record review, including all children at five tertiary-care institutions presenting with button batteries impacted in the aerodigestive tract between January 2002 and December 2014. Battery type/size, duration and location of impaction, presenting symptoms, treatment, complications, and outcomes were examined. RESULTS: Eighty-one patients were included (64.2% male), with ingestion witnessed in 20 (24.7%). Median age at presentation was 3 years (range, 1 week-14 years). Median time from diagnosis to removal was 2.5 hours (range, 0.4-72 hours). Locations included the esophagus (n = 48), hypopharynx (n = 1), stomach (n = 6), nasal cavity (n = 22), and ear canal (n = 4). Most common symptoms for esophageal/hypopharyngeal impactions included dysphagia (26.5%), nausea/vomiting (26.5%), drooling (24.5%), cough (18.4%), and fever (18.4%). Most common symptoms for nasal impactions included epistaxis (54.6%), rhinorrhea (40.9%), nasal pain (27.3%), and fever (22.7%). Almost all esophageal impactions were from 3-V (89.5%), 20-mm (81.8%) lithium batteries. Severe esophageal complications included stricture (28.6%), perforation (24.5%), tracheoesophageal fistula formation (8.2%), pneumothorax (4.1%), and bilateral true vocal fold paresis (4.1%). Nasal complications included necrosis (59.1%), septal perforation (27.3%), and saddle nose deformity (4.5%). Duration of impaction correlated with an increased likelihood of persistent symptoms only for nasal batteries (P = .049). CONCLUSIONS: Button batteries in the upper pediatric aerodigestive tract or ear canal should be considered a surgical emergency, requiring urgent removal and careful vigilance for complications.

Angioedema: a review of 367 episodes presenting to three tertiary care hospitals.

OBJECTIVES: We evaluated the clinical characteristics of patients treated for angioedema, and determined the factors associated with the clinical course. METHODS: We performed a chart review of 367 episodes presenting from 1997 through 2008. RESULTS: The mean (+/-SD) age was 51.8 +/- 20.1 years; 65.7% of the episodes occurred in female patients; 62.4% of the episodes were in African American patients. The patients were on angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) for 49.1% of the episodes, and an inciting factor (diet change, minor trauma, or exposure to fumes) was present for 21.5%. We found that 75.7% of the episodes were type 1 angioedema, 5.7% were type 2, 1.4% were type 3, and 17.2% involved multiple sites; 58% of the episodes required admission. For 3.3% of the episodes, the patients were intubated, and in 0.3% of the episodes, the patients required a tracheostomy. Logistic regression identified non-African American race, allergies, alcohol use, use of ACE inhibitors or ARBs, multiple sites, and age as associated with the need for admission. Bivariate analysis identified age, multiple affected sites, stridor, hoarseness, dysphagia, and drooling as associated with intubation or tracheostomy. CONCLUSIONS: The novel findings of this study are lower rates of airway intervention than reported previously and the fact that multiple affected sites were associated with admission and intubation or tracheostomy, particularly when the edema involved the larynx or hypopharynx.

The Generalizability of the Clinical Assessment Score-15 for Pediatric Sleep-Disordered Breathing.

OBJECTIVE: The Clinical Assessment Score-15 (CAS-15) has been validated as an office-based assessment for pediatric sleep-disordered breathing in otherwise healthy children. Our objective was to determine the generalizability of the CAS-15 in a multi-institutional fashion. METHODS: Five hundred and thirty children from 13 sites with suspected sleep-disordered breathing were recruited, and the investigators completed the CAS-15. Based on decisions made in the course of clinical care, investigators recommended overnight polysomnography, observation, medical therapy, and/or surgery. Two hundred and forty-seven subjects had a follow-up CAS-15. RESULTS: Mean age was 5.1 (2.6) years; 54.2% were male; 39.1% were white; and 37.0% were African American. Initial mean (standard deviation [SD]) CAS-15 was 37.3 (12.7), n = 508. Spearman correlation between the initial CAS-15 and the initial apnea-hypopnea index (AHI) was 0.41 (95% confidence interval [CI], 0.29, 0.51), n = 212, P < .001. A receiver-operating characteristic curve predicting positive polysomnography (AHI > 2) had an area under the curve of 0.71 (95% CI, 0.63, 0.80). A score ≥ 32 had a sensitivity of 69.0% (95% CI, 61.7, 75.5), a specificity of 63.4% (95% CI, 47.9, 76.6), a positive predictive value of 88.7% (95% CI, 82.1, 93.1), and a negative predictive value of 32.9% (95% CI, 23.5, 44.0) in predicting positive polysomnography. Among children who underwent surgery, the mean change (SD) score was 30.5 (12.6), n = 201, t = 36.85, P < .001, effect size = 3.1. CONCLUSION: This study establishes the generalizability of the CAS-15 as a useful office tool for the evaluation of pediatric sleep-disordered breathing.

The impact of adenotonsillectomy on pediatric asthma.

OBJECTIVE: To determine asthma outcomes in children undergoing adenotonsillectomy (T&A) for treatment of sleep-disordered breathing (SDB). HYPOTHESIS: Asthmatic children will demonstrate improvement in asthma control after T&A compared to asthmatic children not undergoing surgical treatment. STUDY DESIGN: Prospective cohort. PATIENT-SUBJECT SELECTION: 80 children with diagnosed asthma, aged 4-11, undergoing T&A and 62 controls matched to the T&A subjects by age, sex, and asthma severity classification. METHODOLOGY: Parents and children completed the Childhood Asthma Control Test (C-ACT) and the Pediatric Sleep Questionnaire (PSQ). Parents were queried regarding the number of asthma exacerbations, the frequency of the use of systemic steroids, the number of emergency room visits and the number of hospitalizations in the prior 6 months. The identical questionnaires and interviews were completed 6 months after entry. RESULTS: The adjusted mean (95% CI) C-ACT score was 21.86 (20.94-22.68) at entry and 25.15 (24.55-25.71) at follow-up for the T&A group compared with 22.42 (21.46-23.28) and 23.59 (22.77-24.33) for the control group. There was a significant group by time interaction (P < 0.001). Simple effects analysis showed that group means did not differ at entry (P = 1.00) but did differ at follow-up (P = 0.006). Baseline PSQ was a significant predictor of improvement in C-ACT scores. Statistical modeling did not demonstrate significant group by time interactions for any of the asthma clinical outcomes, although these outcomes were very infrequent in both groups. CONCLUSION: Treatment of SDB improves asthma outcomes as measured by the C-ACT.

Effect of intracapsular tonsillectomy on quality of life for children with obstructive sleep-disordered breathing.

OBJECTIVE: To assess the change in disease-specific quality of life (QOL) in pediatric patients with obstructive sleep-disordered breathing (OSDB) secondary to adenotonsillar hypertrophy after powered intracapsular tonsillectomy and adenoidectomy. DESIGN: Prospective outcomes study. SETTING: Hospital-based pediatric otolaryngology practice. PATIENTS: Fifty children with a mean age of 4.5 years who had a clinical diagnosis of OSDB. INTERVENTIONS: A caregiver of qualifying patients completed a validated QOL survey of pediatric obstructive sleep apnea, the OSA-18 (Obstructive Sleep Apnea-18), preoperatively and 3 months and 1 year postoperatively. MAIN OUTCOME MEASURE: The OSA-18 mean change scores. RESULTS: The mean (SD) total OSA-18 change score at the 3-month follow-up visit was 2.3 (1.2) and at the 1 year follow-up visit was 2.2 (1.3). The total and individual domain change scores were significantly improved at both postoperative intervals (P<.001 for all). There were no significant changes in the total or domain change scores between the intervals. The total change score was not significantly associated with either tonsil size or tonsil position. CONCLUSION: The OSDB-related QOL is significantly improved after powered intracapsular tonsillectomy and adenoidectomy, and this improvement remains stable even after 1 year.

Quality of life after tonsillectomy in adults with recurrent or chronic tonsillitis.

OBJECTIVE: To describe changes in disease-specific and global quality of life (QOL) for adults with recurrent or chronic tonsillitis at 6 months and 1 year after tonsillectomy using two instruments: the Tonsil and Adenoid Health Status Instrument (TAHSI) and the SF-12 Health Survey (12-item short form of SF-36 Health Survey). STUDY DESIGN AND SETTING: Multicenter, prospective observational outcomes study. RESULTS: Seventy-two adults, mean age 28.0 years (SD 7.2 years), were enrolled with follow-up available for 42 adults at 6 months and for 40 adults at 1 year. Patients showed significant improvements in all six subscales of the TAHSI: airway and breathing, infection, health care utilization, cost of care, eating and swallowing, and behavior (all P < 0.0001). Significant improvements were also found in the physical functioning subscale of the SF-12 at 1 year. CONCLUSION: After tonsillectomy for recurrent and chronic tonsillitis, we found large improvements in disease-specific and global QOL. SIGNIFICANCE: Most prior studies on tonsillectomy for recurrent tonsillitis have assessed only the frequency of infections as an outcome measure. This study describes the changes in QOL measured in our cohort of reporting adults after tonsillectomy for chronic or recurrent tonsillitis. This study provides prospective evidence of the effectiveness of tonsillectomy on adult QOL.

Quality of life after tonsillectomy in children with recurrent tonsillitis.

OBJECTIVE: To describe changes in disease-specific and global quality of life (QOL) for children with recurrent or chronic tonsillitis at 6 months and 1 year after tonsillectomy using two validated instruments, the Tonsil and Adenoid Health Status Instrument (TAHSI) and the Child Health Questionaire-PF28 (CHQ-PF28). STUDY DESIGN AND SETTING: A multicenter, prospective observational outcomes study. RESULTS: Ninety-two children, mean age (SD) 10.6 (3.4) years, enrolled with follow-up available for 58 children at 6 months and 38 children at 1 year. The children showed significant improvements in all subscales of the TAHSI including airway and breathing, infection, health care utilization, cost of care, eating and swallowing (all P < 0.001), and behavior (P = 0.01). Significant improvements were also found on several subscales of the CHQ-PF28, such as general health perceptions, physical functioning, parental impact, and family activities (all P < 0.001). CONCLUSION/SIGNIFICANCE: This uncontrolled study provides prospective evidence of improved disease-specific and global QOL in children after tonsillectomy.

Endoscopic Sinus Surgery Improves Sleep Quality in Chronic Rhinosinusitis: A Systematic Review and Meta-analysis.

Objective Up to 75% of patients with chronic rhinosinusitis (CRS) suffer with poor sleep quality and reduced quality of life. Endoscopic sinus surgery has demonstrated encouraging results in improving sleep function. The aim of this systematic review is to assess the change in sleep quality after surgery for CRS. Data Sources PubMed, Web of Science, EMBASE. Review Methods An electronic search was conducted with the keywords "sinusitis" or "rhinosinusitis" and "sleep." Studies were included only when adults underwent endoscopic sinus surgery and were evaluated pre- and postoperatively by the Epworth Sleepiness Scale (ESS), the Pittsburgh Sleep Quality Index (PSQI), the Apnea-Hypopnea Index (AHI), the sleep domain of Sino-Nasal Outcome Test-22, or the sleep domain of Rhinosinusitis Disability Index. Results The database search yielded 1939 studies, of which 7 remained after dual-investigator screening. The standardized mean differences (95% CI) for the ESS, PSQI, and AHI were -0.94 (-1.63 to -0.26), -0.80 (-1.46 to -0.14), and -0.20 (-0.32 to -0.07), indicating large, moderate to large, and small improvements, respectively. All analyses displayed high heterogeneity ( I2 = 95%-99%). Conclusion Sleep quality, as measured by the ESS and PSQI surveys, shows substantial improvement after surgery for CRS, with smaller improvement seen for AHI. Generalizability of our results is limited by high heterogeneity among studies and by broad confidence intervals that cannot exclude small to trivial changes. The findings of this meta-analysis provide insight into the effect of CRS-related endoscopic sinus surgery on sleep quality, which should guide future research direction and counseling of patients in the clinical setting.

Managing isolated subglottic juvenile xanthogranuloma without tracheostomy: case report and review of literature.

Juvenile Xanthogranuloma (JXG) is a dendritic cell related histiocytic disorder which usually presents in the first year of life as a solitary cutaneous granuloma. Isolated presentation in the upper airway is very rare but can result in severe respiratory distress, especially in young children. We present the case of a 5-month-old male with an isolated subglottic JXG lesion. Endoscopic excision provided symptomatic relief and avoided the need for tracheostomy. The lesion has completely resolved 17 months later. Surgical excision without tracheostomy was the treatment of choice in two of the four additional cases of upper airway JXG presented in the literature. JXG has an excellent prognosis with spontaneous regression over time. Histology alone is frequently inadequate to differentiate JXG from the more common Langerhans Cell Histiocytosis (LCH), which carries a much less favorable prognosis. The evolving field of immunohistochemistry provides an essential tool to establish the correct diagnosis. The typical phenotype of JXG is Factor XIIIa+/Fascin+/CD68+/CD163+/CD14+/CD1a-/S100-.

An Extubation Protocol for Angioedema.

Angioedema-nonpitting edema of the mucous membranes and skin-most commonly occurs as a complication from the use of angiotensin-converting enzyme inhibitors. At our institution, the otolaryngology department has incorporated the use of the endotracheal tube cuff-leak test and bedside direct laryngoscopy to aid in timing for extubation of angioedema patients. Prospective data collection of patients presenting to the emergency department with angioedema was performed. Of 76 patients with angioedema, 9 required fiberoptic intubation. Intubation was performed at a median of 73 hours (range, 44-118). An endotracheal tube cuff-leak test was performed in 7 patients prior to extubation, and bedside direct laryngoscopy was also performed in 3 of these 7 patients to document resolution of laryngeal edema. The use of the endotracheal tube cuff-leak test and bedside direct laryngoscopy is an easy and inexpensive method to help determine eligibility for extubation in patients intubated for angioedema.

Postobstructive pulmonary edema after laryngospasm in the otolaryngology patient.

CONTEXT: Post-obstructive pulmonary edema (PPE) is an uncommon complication which develops immediately after the onset of acute airway obstruction such as laryngospasm or epiglottitis (type I) or after the relief of chronic upper airway obstruction such as adenotonsillar hypertrophy (type II). OBJECTIVE: To describe the development of type I PPE following laryngospasm in pediatric and adult patients undergoing otolaryngologic surgical procedures other than those for treatment of obstructive sleep apnea. DESIGN: Retrospective case series of 13 otolaryngology patients from 1996 to 2003. SETTING: Tertiary care teaching hospital and its affiliates. PATIENTS: 13 patients (4 children, 9 adults, 5 males, 8 females) ranging in age from 9 months to 48 years. RESULTS: Operative procedures included adenoidectomy, tonsillectomy, removal of an esophageal foreign body, microlaryngoscopy with papilloma excision, endoscopic sinus surgery, septorhinoplasty, and thyroidectomy. Six patients required reintubation. Treatment included positive pressure ventilation, oxygen therapy, and diuretics. Seven patients were discharged within 24 hours and the others were discharged between 2 and 8 days postoperatively. There were no mortalities. CONCLUSION: Laryngospasm resulting in PPE may occur in both children and adults after various otolaryngologic procedures. Among the subgroup of children, our study is the first to report its occurrence in healthy children without sleep apnea undergoing elective surgery.

Intraoperative evaluation of a pulsatile oropharyngeal mass during adenotonsillectomy.

Iatrogenic injury to the internal carotid artery (ICA) is a rare complication of pharyngeal surgery that most commonly occurs in children with an anomalous course to the internal carotid artery. Most aberrant arteries are asymptomatic. They can remain undiscovered preoperatively or be found incidentally on radiographic studies completed for an unrelated reason. Evaluation of definitive internal carotid artery injuries is well documented in the trauma literature. We present a case of a suspected intraoperative injury to the internal carotid artery during routine pharyngeal surgery. Ultimately no injury was found, however, aberrant internal carotid arteries were coincidentally discovered.

The safety of preoperative sedation in children with sleep-disordered breathing.

OBJECTIVE: To prospectively monitor children who received preoperative sedation with midazolam hydrochloride prior to adenotonsillectomy (T&A) for treatment of sleep-disordered breathing with continuous pulse-oximetry to detect potential respiratory compromise. DESIGN: Prospective, observational study. SETTING: Hospital-based pediatric otolaryngology practice. PATIENTS: Seventy children, aged 1-12 years, diagnosed with sleep-disordered breathing by clinical evaluation or polysomnography (PSG), with a median RDI of 14.25, undergoing T&A. METHODS: Children underwent a standardized anesthesia protocol including preoperative oral midazolam hydrochloride 0.5mg/kg, standard American Society of Anesthesiologists (ASA) monitoring, mask induction with sevoflurane, muscle relaxant with reversal if indicated, and intravenous dexamethasone sodium phosphate 0.5mg/kg. Children were monitored in the hospital until discharge criteria were met. Selected children with severe OSA were monitored overnight on the pediatric floor or the pediatric intensive care unit. Adverse respiratory events were defined as upper airway obstruction, hypoventilation, desaturation, bradycardia, or sustained lethargy. MAIN OUTCOME MEASURES: Incidence of pre and postoperative obstructive complications. RESULTS: During the study period only two patients (2.9%) had a measurable adverse event directly related to the administration of the sedation. CONCLUSION: Based on sporadic reports of adverse airway events in children with obstructive sleep apnea receiving sedation, these children frequently do not receive preoperative sedation. Given the low morbidity of preoperative sedation in our population, many children with sleep-disordered breathing may safely be pre-medicated.
