Prospective comparative study of pulsed-electron avalanche knife (PEAK) and bipolar radiofrequency ablation (coblation) pediatric tonsillectomy and adenoidectomy.

PURPOSE: To compare post-operative pain severity, analgesic intake, and complications in children undergoing tonsillectomy and adenoidectomy with bipolar radiofrequency ablation (Coblation) vs. pulsed-electron avalanche knife (PEAK) technology. MATERIALS AND METHODS: This was a prospective, non-randomized, non-blinded comparative cohort study in a private practice setting with three fellowship-trained pediatric otolaryngologists. Patients aged 3 to 12years undergoing tonsillectomy and adenoidectomy were assigned to surgery with either bipolar radiofrequency ablation or pulsed electron avalanche knife instrumentation. Daily telephone contact for the first 14 post-operative days obtained the following data: validated proxy pain scale scores, number of post-operative analgesic medication doses consumed, and occurrence and severity of post-operative hemorrhage. RESULTS: One-hundred adenotonsillectomy subjects were enrolled (50 bipolar radiofrequency ablation, 50 pulsed-electron avalanche knife). There were no clinically relevant differences in post-operative pain scores between the two surgical groups on all post-operative days. Total doses of non-narcotic and narcotic analgesics were similar between the groups, with the exception of less acetaminophen doses being consumed in pulsed-electron avalanche knife patients on post-operative days 9, 10, and 12. Post-operative hemorrhage episodes resulting in re-operation and/or hospitalization were equivalent between the two groups. However, bipolar radiofrequency ablation patients were 2.33 times more likely to experience minor bleeding events at home (that did not require medical intervention). CONCLUSION: Pulsed-electron avalanche knife surgery was found to be an adequate technique for pediatric adenotonsillectomy, with similar amounts of post-operative pain and clinically relevant hemorrhage when compared to bipolar radiofrequency ablation.

Risk factors for pediatric post-tonsillectomy hemorrhage.

OBJECTIVES: To determine pre-operative risk factors for post-tonsillectomy secondary hemorrhage in children, and quantify the magnitude of their risk. MATERIALS AND METHODS: Retrospective case-control study of all pediatric tonsillectomy patients experiencing post-operative bleeding from 2005 to 2010 in a community practice consisting of three fellowship-trained pediatric otolaryngologists were identified. The 91 cases were matched with 151 controls that underwent tonsillectomy by the same surgeon on the same day as each identified case. All charts were reviewed, and 41 pre-operative variables were extracted and statistically analyzed with contingency and regression analysis to calculate significance and odds ratios. RESULTS: Three significant predictors of post-operative bleeding were identified. Performing a tonsillectomy on a child with recurrent tonsillitis (vs. other indications) increased the risk of post-operative hemorrhage by 4.5 times (p<0.0001, 95% confidence intervals 2.41-8.38). Performing a tonsillectomy on a child with attention deficit hyperactivity disorder (ADHD) increased the risk by 8.7 times (p=0.029, 95%CI 1.4-53.6). Older children were more predisposed to post-operative bleeding. For every increase in age by one year, the hemorrhage risk increased by 1.1 times (p=0.0025, 95%CI 1.032-1.162). Children 11 years of age and older had double the risk of bleeding compared to younger children (odds ratio 1.98, p=0.0381, 95%CI 1.04-3.79). None of the remaining 38 variables showed significant differences between cases and controls. CONCLUSIONS: The risk of post-tonsillectomy hemorrhage is significantly increased in older children and those with recurrent tonsillitis and ADHD.

Laryngomalacia and swallowing function in children.

OBJECTIVES/HYPOTHESIS: 1) To determine the prevalence of dysphagia in children with laryngomalacia, 2) To ascertain whether severity of laryngomalacia influences the presence of swallowing dysfunction, and 3) To examine whether patients with medical comorbidities and laryngomalacia have a higher prevalence of swallowing dysfunction. STUDY DESIGN: Retrospective cohort study. METHODS: All patients seen in the aerodigestive center at our institution between January 2007 and December 2012 with the diagnosis of laryngomalacia were included. Swallowing function was assessed by symptoms, clinical swallowing evaluations (CSE) performed by speech pathologists, modified barium swallow (MBS) studies, and fiberoptic endoscopic evaluations of swallowing (FEES). RESULTS: There were 324 patients with laryngomalacia identified (41.4% female, 58.6% male). Severity of laryngomalacia was categorized in 279 patients, with 62.7% mild, 28.7% moderate, and 8.6% severe. Gastroesophageal reflux disease (GERD) was diagnosed in 69.8% of patients. Other medical comorbidities included Down syndrome (3.1%), neurological impairment (6.5%), and congenital heart disease (0.9%). Symptoms of dysphagia or feeding difficulty were present in 163/324 (50.3%), and failure to thrive was present in 31/324 patients (9.6%). At least one abnormal swallowing assessment was present in 97/120 (80.8%) patients presenting with subjective dysphagia and 43/65 (66.2%) patients without subjective dysphagia. A total of 140/185 (75.7%) patients had at least one abnormal baseline swallowing assessment. There was no significant relationship between severity of laryngomalacia and presence of abnormal swallowing function based on symptoms, CSE, MBS, or FEES. However, patients with greater severity were more likely to have failure to thrive. There was not a significant association between the presence of swallowing dysfunction or disease severity and medical comorbidities such as Down syndrome, neurological impairment, or congenital heart disease. However, GERD was more likely to be present in patients with moderate and severe laryngomalacia than in patients with mild disease. CONCLUSIONS: Swallowing dysfunction is common in children with laryngomalacia regardless of disease severity or other medical comorbidities. Swallowing studies are frequently abnormal in laryngomalacia patients presenting both with and without subjective symptoms of dysphagia. Dysphagia assessment should be considered as part of the evaluation of infants with laryngomalacia. LEVEL OF EVIDENCE: 4.

Pediatric sialendoscopy: initial experience in a pediatric otolaryngology group practice.

OBJECTIVES/HYPOTHESIS: To describe the initial results of sialendoscopy as a diagnostic and therapeutic tool in pediatric inflammatory salivary gland disease. STUDY DESIGN: Retrospective review of patient medical records from a private practice consisting of three fellowship-trained pediatric otolaryngologists. METHODS: Consecutive pediatric patients with either recurrent or chronic sialadenitis underwent diagnostic and therapeutic sialendoscopy as an alternative to continued antibiotic therapy or surgical gland excision. Data collected included age, gender, indications for surgery, intraoperative findings, complications, recurrences, follow-up intervals, and need for additional procedures. RESULTS: Twelve pediatric patients underwent sialendsocopy (9 cases of juvenile recurrent parotitis, 3 cases of chronic submandibular sialadenitis. Intraoperative findings included ductal stricture (n = 8), thick intraductal mucus (n = 6), and ductal calculus (n = 1). The only postoperative complication was one case of a submandibular gland, which remained enlarged for 1 month postoperatively before resolving. Average follow-up was 16.5 months (range: 1-49 months), during which time two patients had recurrence (17%). One patient had repeated recurrences that only resolved after salvage parotidectomy. Another patient had one isolated recurrence that resolved with antibiotics. To date, 92% of patients have not required any further surgical intervention after a sialendoscopy procedure. CONCLUSIONS: Sialendoscopy was successfully implemented as a safe and effective technique for management of recurrent and chronic parotid and submandibular sialadenitis in a pediatric otolaryngology practice. LEVEL OF EVIDENCE: 4.

Impact of stoma maturation on pediatric tracheostomy-related complications.

OBJECTIVES: To assess the impact of stoma maturation on pediatric tracheostomy-related complications and to report the incidence of pediatric tracheostomy-related complications. DESIGN: Retrospective medical chart review and data analysis. SETTING: Tertiary care children's hospital. PATIENTS: A total of 172 consecutive patients who underwent tracheotomy during a 4-year period. INTERVENTION: Tracheotomy with or without stoma maturation at the time of surgery was performed by 8 pediatric otolaryngologists. Stoma maturation was based solely on individual surgeon preference, not on patient factors. MAIN OUTCOME MEASURES: Early and late tracheostomy-related complications; correlation between stoma maturation and complication rate. RESULTS: The patients' mean (SD) age was 4.9 (6.6) years, with a mean follow-up of 35.4 (24.5) months. Of 156 patients for whom stoma maturation data were available, 48 (30.8%) underwent stoma maturation and 108 (69.2%) did not. Nineteen of 172 patients (11.0%) had an early complication (within the first 7 days), including accidental decannulation, bleeding, false tract, pneumonia, and tracheitis. Late complications included suprastomal tracheal granulation tissue (48.8%), tracheitis (48.8%), peristomal granulation tissue (26.7%), accidental decannulation (11.6%), and mucus plugging (9.9%). Among the 62 patients (36.0%) who were decannulated, 23 of 62 (37.1%) developed a persistent tracheocutaneous fistula. Younger patients had a higher rate of suprastomal granulation tissue, tracheitis, tracheocutaneous fistula, and repeated surgical procedures (P < .05). Patients with stoma maturation were incidentally older than patients without stoma maturation (P < .05). When corrected for age, stoma maturation did not have an impact on the incidence of any of the tracheostomy-related complications. CONCLUSION: There was no relationship between stoma maturation and tracheostomy-related complications, including rate of tracheocutaneous fistula and development of granulation tissue.

Assessment of constipation in children with tracheostomy.

OBJECTIVE: To determine the prevalence of constipation among children with tracheostomy tubes compared with children without tracheostomy tubes. We theorize that patients with tracheostomy may be unable to achieve adequate subglottic pressure for the Valsalva maneuver, which may contribute to constipation. DESIGN: Prospective cohort study. SETTING: Tertiary care children's hospital. PATIENTS: Consecutive series of 36 children with tracheostomy and 72 general pediatric otolaryngology patients without tracheostomy. INTERVENTIONS: A pediatric constipation questionnaire (from previously published references) was given to parents of the study participants. Data were collected regarding patient medications, neurological status, and use of positive pressure airway assistance, speaking valves, and feeding tubes. Data were evaluated using chi(2) and t tests. Logistic regression analysis was used to search for independent variables impacting presence of constipation. RESULTS: The mean ages for the tracheostomy and control groups were 6.8 and 4.7 years, respectively (P = .07). A history of constipation was elicited in 60% of children with tracheostomy compared with only 16.7% of controls (P < .001). More patients with tracheostomy tubes (80.0%) than controls (20.8%) were taking medication to treat constipation (P < .001). Constipation was also significantly associated with older age (P = .02), use of medications with constipation as a known adverse effect (P = .02), and the presence of neurodevelopmental impairment (P < .001). Constipation was still independently associated with the presence of a tracheostomy tube when correcting for age and the use of constipation-causing medications. When controlling for neurodevelopmental impairment, the presence of a tracheostomy tube was not proven to be an independent predictor of constipation. CONCLUSION: Children with tracheostomy tubes are more likely to have a history of constipation, although a causal relationship between tracheostomy and constipation could not be determined due to the potentially confounding variable of neurodevelopmental delay.

Clinical predictors of aspiration on radionuclide salivagrams in children.

OBJECTIVE: To determine patient characteristics and clinical factors that are predictive of positive radionuclide salivagram results. DESIGN: Retrospective chart review (spanning 32 months). SETTING: Tertiary care children's hospital. PATIENTS: The study included 129 consecutive pediatric patients with suspected chronic aspiration. INTERVENTION: All subjects underwent radionuclide salivagrams to evaluate for aspiration. MAIN OUTCOME MEASURES: The association of 16 patient characteristics and clinical factors (eg, age, sex, diagnoses, study indications, medications, and previous surgical procedures) with salivagram results. Each factor was examined individually (chi(2) or Fisher exact test). For those factors that were significantly associated with positive salivagram results, the risk was estimated with the odds ratio (OR). A multivariable logistic regression model was constructed to determine how well significantly associated factors together predicted positive salivagram results. RESULTS: The mean (SD) patient age was 4.5 (5.4) years. There were 84 boys (65%) and 45 girls (35%). Aspiration was identified in 27 of 129 salivagrams (21%). On univariate analysis, positive salivagram results were significantly associated with chronic respiratory infections and/or pneumonia (OR, 2.6), prescription of antireflux medications (OR, 2.7), developmental delay (OR, 2.8), and reactive airway disease exacerbations (OR, 3.3) (P<.05). None of the other clinical factors were significantly associated with salivagram results. On multivariate analysis, salivagram results were significantly associated with the 4 above-mentioned factors (P = .009). However, these 4 predictive factors were not independent of each other owing to the statistically significant associations among them. CONCLUSIONS: We identified 4 clinical factors that are predictive of aspiration on salivagram. A high level of suspicion for aspiration should be maintained in children with these potential risk factors.

Fine needle aspiration biopsy: role in diagnosis of pediatric head and neck masses.

OBJECTIVE: To assess the feasibility and role of fine needle aspiration biopsy (FNAB) as a diagnostic tool in children with neck masses. DESIGN: Retrospective chart review. SETTING: Tertiary care children's hospital. PATIENTS: Consecutive series of 71 children with a head and neck mass who underwent FNAB as the primary diagnostic modality. INTERVENTIONS: FNAB was performed and interpreted by a pediatric cytopathologist. Rapid on-site analysis was performed to allow immediate assessment of specimen adequacy and to attain a preliminary diagnosis, after which routine cytologic staining was performed. Flow cytometry was performed on cytological specimens when malignancy was suspected, and open biopsy was performed when the cytologic diagnosis was in question. MAIN OUTCOME MEASURES: Technical feasibility of FNAB in children, complications, cytopathological diagnoses, accuracy of rapid on-site analysis, need for subsequent diagnostic evaluations, clinical outcomes and follow-up. RESULTS: Mean age was 8.4 years (S.D. 5.3 years), with mean follow-up of 4.1 months (S.D. 9.6 months). FNAB was performed under general anesthesia in 54 cases (76%). There were no technical complications. On-site rapid interpretation was completed in 55 cases, 18/55 confirmed adequacy of specimen only, 37/55 yielded a preliminary diagnosis, and in 34/37 cases, was same as final cytopathologic result. Overall, FNAB biopsy demonstrated 64 benign lesions, 3 malignant diagnoses, 2 follicular thyroid neoplasms, and 2 non-diagnostic specimens. FNAB was the only pathological test performed in 54 (76%) cases. The most common diagnosis was reactive lymphoid hyperplasia (n = 39), followed by benign granulomatous disease (n = 8). Flow cytometry was performed on 7 specimens (non-diagnostic in 5, negative for malignancy in 2). Of the 15 cases with surgical specimens, 3 revealed a pathologic diagnosis different from initial FNAB. There were no cases in which FNAB missed a malignancy, and there were 2 cases where FNAB suggested malignancy, with benign disease subsequently found on open biopsy. CONCLUSIONS: Fine needle aspiration biopsy is developing into a feasible option in diagnosing pediatric neck masses, with its main advantage being its minimally-invasive nature and avoidance of an open surgical procedure for benign persistent lymphadenitis. On-site rapid interpretation can be used successfully to confirm specimen adequacy and to give an accurate preliminary diagnosis for concerned parents. Issues to consider include the need for a specialized pediatric cytopathologist familiar with pediatric differential diagnoses, the need for general anesthesia in many cases, and the possibility of inaccurate diagnosis requiring an open procedure.

Comparison of Pediatric Voice Outcome Survey, Reflux Symptom Index, Reflux Finding Score, and esophageal biopsy results.

OBJECTIVE: To examine correlations between the Pediatric Voice Outcome Survey (PVOS) score, the Reflux Symptom Index (RSI) score, the Reflux Finding Score (RFS), and esophageal biopsy findings in children undergoing upper aerodigestive tract endoscopy. DESIGN: Retrospective review of pediatric voice quality-of-life and laryngopharyngeal reflux surveys. Blinded assessment of endoscopic laryngeal images. SETTING: Tertiary care children's hospital. PATIENTS: The study included 36 children with the primary problem of dysphonia (n = 28) or cough (n = 8) who underwent endoscopy. INTERVENTIONS: The PVOS and the RSI were administered to the patient's parents before surgery. The patients underwent laryngotracheobronchoscopy and esophageal biopsy. Four raters independently assigned an RFS to the laryngeal photographs. MAIN OUTCOME MEASURES: The assessment included (1) PVOS scores, RSI scores, and RFSs; (2) internal consistency of PVOS and RSI scores; (3) RFS intrarater and interrater reliability; and (4) correlations between PVOS score, RSI score, RFS, and esophageal biopsy findings. RESULTS: The mean (SD) age of the patients was 7.5 (2.6) years; the mean (SD) PVOS score, 71.9 (21.4); and the mean (SD) RSI score, 16.2 (9.1). The PVOS and the RSI scores demonstrated good internal consistency (Cronbach alpha = 0.79 and 0.78, respectively). The RFS exhibited good intrarater reliability (r = 0.66-0.98) and moderate interrater reliability (r = 0.32-0.70). The PVOS and RSI instruments displayed significant correlation (r = -0.30; P = .04). There were no other significant correlations between RFSs, esophageal biopsy results, PVOS scores, or RSI scores (P > .05). CONCLUSIONS: The RSI may be a useful parent-proxy instrument in addition to the PVOS for pediatric voice patients. The RFS is reliable in children, but its validity could not be demonstrated in this patient population.

Synchronous airway lesions and esophagitis in young patients undergoing adenoidectomy.

OBJECTIVE: To determine the prevalence of synchronous airway lesions and esophagitis in children younger than 18 months undergoing adenoidectomy for adenoid hypertrophy and upper airway obstruction. DESIGN: Retrospective review spanning 4.5 years. SETTING: Tertiary care children's hospital. PATIENTS: All children younger than 18 months who underwent adenoidectomy for upper airway obstruction by 2 pediatric otolaryngologists. EXCLUSION CRITERIA: craniofacial dysmorphism and congenital syndromes. INTERVENTIONS: Simultaneous interventions during adenoidectomy included flexible nasopharyngolaryngoscopy (n = 32), direct laryngoscopy (n = 31), rigid tracheobronchoscopy (n = 30), and esophagoscopy with biopsy (n = 32). MAIN OUTCOME MEASURES: Prevalence of synchronous airway lesions and histologic esophagitis. RESULTS: Thirty-five children younger than 18 months underwent adenoidectomy for airway obstruction (2 also had simultaneous tonsillectomy). Synchronous airway lesions were found in 19 (59%) of 32 patients who underwent airway endoscopy, including laryngeal edema (n = 9), laryngomalacia (n = 8), tracheal vascular compression (n = 4), subglottic stenosis (n = 4), midmembranous vocal fold lesions (n = 3), bronchial stenosis (n = 1), and true vocal fold immobility (n = 1). Among 32 patients who underwent esophageal biopsy, histologic evidence of gastroesophageal reflux disease was found in 10 patients (31%), and eosinophilic esophagitis was found in 4 patients (13%). Overall prevalence of any synchronous finding (airway and/or esophagus) was 27 (77%) of 35. CONCLUSIONS: Synchronous airway lesions and esophagitis (both gastroesophageal reflux disease and eosinophilic esophagitis) were prevalent among children younger than 18 months undergoing adenoidectomy for adenoid hypertrophy and upper airway obstruction. The presence of these findings argues for consideration of endoscopy during adenoidectomy for very young children.

Introduction of visually oriented information handouts in an academic pediatric otolaryngology practice.

OBJECTIVES: To characterize after-hours postoperative caregiver telephone calls received by on-call otolaryngology residents and to determine the feasibility of using visually oriented handouts to affect postoperative telephone call volume. STUDY DESIGN AND SETTING: We conducted a prospective, before-after feasibility study at a tertiary-care children's hospital. Visually oriented handouts describing expected postoperative courses were distributed preoperatively to the parents of all adenotonsillectomy and tympanostomy tube patients. Postoperative caregiver telephone call volume and content were recorded before and after handout introduction. RESULTS: The handouts were well accepted and viewed favorably by caregivers, and they led to some changes in the nature of postoperative telephone call content, but call log compliance was not adequate to fully assess the impact on call volume and content. CONCLUSIONS: We demonstrated the feasibility of implementing visually oriented informational handouts and characterized the nature of postoperative caregiver telephone calls received by on-call residents in an academic pediatric otolaryngology practice. SIGNIFICANCE: Visually oriented instructional handouts may have benefits that deserve further study. Data from this study can help plan a definitive clinical trial.

Bilateral peritonsillar abscesses: case report and literature review.

Although unilateral peritonsillar abscesses (PTA) are a common complication of acute bacterial tonsillitis, bilateral PTA are quite rare. We present the case of a 14-year-old female teenager with a 1-week history of acute tonsillitis. Physical examination revealed significant trismus, symmetrically inflamed tonsils and soft palate, and a midline uvula. A contrast-enhanced CT scan of the neck demonstrated bilateral PTA. After bilateral needle aspiration and administration of antibiotics, complete disease resolution was rapidly achieved. Patients with bilateral PTA present a diagnostic dilemma because they do not demonstrate the classic asymmetric signs and symptoms seen in the more prevalent unilateral PTA. Contrast-enhanced CT imaging can help diagnose bilateral PTA and should be considered in the presence of marked trismus but with the absence of unilateral inflammatory findings.

Evaluation and management of pediatric oropharyngeal trauma.

OBJECTIVE: To examine the clinical factors that influence medical decision making in children with oropharyngeal trauma. DESIGN: Retrospective chart review (spanning 6 years). SETTING: Tertiary care children's hospital. PATIENTS: One hundred seven consecutive children with traumatic oropharyngeal injuries. INTERVENTIONS: Computed tomographic angiography (CTA) (n = 52), surgical therapy (n = 16), inpatient admission (n = 44), and antibiotic administration (n = 77). MAIN OUTCOME MEASURES: The likelihood of a patient undergoing each of the 4 interventions and having positive radiographic findings or clinical complications was assessed with respect to the following clinical factors: (1) age, (2) sex, (3) mechanism of injury, (4) site of injury, (5) wound severity (3-point scale), and (6) otolaryngology consultation. RESULTS: The following factors were significantly associated with an increased likelihood of a patient undergoing CTA to rule out occult internal carotid artery damage: (1) injury to the lateral soft palate, (2) high wound severity score, and (3) otolaryngology consultation. Radiographic abnormalities (including free air, parapharyngeal edema, and hematoma) were present in 16 (31%) of 52 CTAs but were not associated with any specific clinical factors. Patients with more severe wounds were more likely to undergo CTA, go to the operating room, receive antibiotics, and be admitted to the hospital but were not more likely to have positive CTA findings or an adverse clinical outcome. CONCLUSIONS: We were unable to identify any clinical factors that would help predict which children with oropharyngeal trauma are at high risk of developing neurologic sequelae. Radiographic screening for vascular injury in children with oropharyngeal trauma remains controversial.

Computed tomography and magnetic resonance imaging in pediatric unilateral and asymmetric sensorineural hearing loss.

OBJECTIVE: To compare temporal bone computed tomography (CT) with temporal bone and central nervous system magnetic resonance (MR) imaging in children with unilateral or asymmetric sensorineural hearing loss (SNHL). DESIGN: Retrospective chart study. SETTING: Tertiary-care children's hospital. PATIENTS: A total of 131 children with unilateral or asymmetric SNHL, seen consecutively by a single practitioner over 36 months. INTERVENTION: Imaging studies were read by a pediatric neuroradiologist and reviewed by the evaluating otolaryngologist. MAIN OUTCOME MEASURE: Prevalence of clinically significant CT or MR imaging findings. RESULTS: The prevalence of CT abnormalities was 35% for unilateral SNHL, 52% for asymmetric SNHL, and 41% for all patients together. The prevalence of MR imaging abnormalities was 25% for unilateral SNHL, 50% for asymmetric SNHL, and 30% for all patients together. Among 42 subjects who underwent both studies, there were 4 cases in which abnormalities were seen only on MR images and 9 cases in which abnormalities were seen only on CT scans. CONCLUSIONS: Temporal bone and/or central nervous system abnormalities were detected in 42% of 131 patients. When both CT scans and MR images were obtained (n = 42), results were concordant in 69% of cases, and one imaging modality detected clinically significant abnormalities not identified by the other in 31% of cases. The ideal imaging algorithm for children with unilateral or asymmetric SNHL is controversial. We suggest that all children with unilateral or asymmetric SNHL have a high-resolution temporal bone CT scan and that brain and temporal bone MR imaging be obtained in select cases.

Superstitions among perioperative nurses.

A descriptive study was conducted using a mailed questionnaire to determine the prevalence of work-related superstitions among perioperative nurses. Data analysis included the two-sample t test for continuous data and the two-sided Fisher's exact test for binary data. Study results indicate that although only 23% of respondents view themselves as "generally superstitious," specific work-related superstitions are widespread. Belief in specific superstitions was not statistically related to age or number of years as a perioperative nurse. An analysis of the literature on medical workplace superstitions helps to elucidate possible underlying explanations for the phenomenon of nursing superstitions.

Lack of association between esophageal biopsy, bronchoalveolar lavage, and endoscopy findings in hoarse children.

OBJECTIVE: To determine the prevalence of esophagitis (based on esophageal biopsy results) and aspiration (based on bronchoalveolar lavage [BAL]) in children with hoarseness. DESIGN: Retrospective medical chart review spanning 24 months of 127 consecutive children (mean age, 6.9 years; range, 1.8-17 years) who presented with hoarseness to 2 attending otolaryngologists. SETTING: Tertiary care children's hospital.Intervention All subjects underwent direct laryngoscopy, rigid bronchoscopy with BAL, and rigid or flexible esophagoscopy with biopsy. MAIN OUTCOME MEASURES: The BAL result was considered positive if the number of lipid-laden macrophages was "moderate" or "large," and the esophageal biopsy result was considered positive if any 2 of the following 3 histologic criteria were present: basal cell hyperplasia, increased papillary height, and intraepithelial inflammatory infiltrate. Comparisons between subjective endoscopic findings and objective test results were made using the t test and contingency table analysis, where appropriate. RESULTS: Of the 127 children, 104 (82%) had vocal nodules; 53 (43%) had endoscopically visualized laryngitis; 36 (28%) had tracheobronchial inflammatory changes; 60 (47%) had abnormal esophagoscopy findings; 47 (37%) had a positive BAL result; and 38 (30%) had a positive esophageal biopsy result. There was no significant correlation between BAL and esophageal biopsy results (P = .11). The odds of having positive BAL or esophageal biopsy results were unaffected by the presence of vocal nodules; endoscopically visualized inflammation of the larynx, trachea, or esophagus; or symptoms or previous clinical history of gastroesophageal reflux disease. CONCLUSION: Positive esophageal biopsy and BAL results are prevalent among children with hoarseness, regardless of subjective upper aerodigestive tract endoscopic findings.

Intralesional cidofovir for pediatric recurrent respiratory papillomatosis.

OBJECTIVE: To compare disease response among children with recurrent respiratory papillomatosis (RRP) who underwent combined surgical debulking and intralesional cidofovir injections vs repeated surgical debulking only. DESIGN: Retrospective medical record review; follow-up range: 16 to 56 months. SETTING: Tertiary care children's hospital. PATIENTS: Seven children with RRP, including 4 subjects treated with cidofovir and 3 controls matched for age and initial papilloma staging score. INTERVENTIONS: Subjects treated with cidofovir underwent combined surgical debulking and intralesional cidofovir injection every 2 months until disease remission. Control subjects underwent repeated surgical debulking at individually determined intervals. MAIN OUTCOME MEASURES: Intraoperative endoscopic photographs were retrospectively assigned papilloma staging scores. Cidofovir and control group comparisons were made using nonparametric 2-sample Wilcoxon rank-sum (Mann-Whitney) testing, and comparisons of initial and final papilloma staging scores were made using nonparametric matched-pair Wilcoxon signed-rank testing. RESULTS: The final cidofovir group scores were significantly lower than the control group scores (P < .05). Within-group differences between initial and final scores were not significant (cidofovir group, P = .07; control group, P = .29). CONCLUSIONS: Four children with RRP were safely and successfully treated with intralesional cidofovir injection. Consideration should be given to using cidofovir more widely for treatment of pediatric RRP. Larger numbers in the cidofovir and control groups are needed in future studies to determine the true impact of cidofovir on management of this disease.

Endoscopic KTP laser excision of severe tracheotomy-associated suprastomal collapse.

OBJECTIVE: The purpose of this study was to investigate the feasibility, safety, and clinical utility of potassium-titanium-phosphate (KTP) laser bronchoscopy for excision of severe, obstructing tracheotomy-associated suprastomal collapse. METHODS: A retrospective review was performed of six children at a tertiary care children's hospital with severe tracheotomy-associated collapse of the suprastomal anterior tracheal wall cartilage, precluding decannulation. All subjects had undergone KTP laser endoscopic excision of the collapsed segment of suprastomal tracheal cartilage. Medical records were assessed for: (1) endoscopic demonstration of relief of suprastomal collapse, and (2) successful tracheotomy decannulation. RESULTS: All six patients had endoscopic evidence of relief of suprastomal airway obstruction after KTP laser therapy. Five of six (83%) subsequently underwent successful decannulation. There was one case of minimal thermal airway injury associated with a laser fire during use of the KTP laser, the effects of which were fortunately transient. CONCLUSIONS: KTP laser bronchoscopic excision of severe tracheotomy-associated suprastomal collapse: (1) is a feasible technique; (2) results in relief of suprastomal obstruction with subsequent successful decannulation in selected patients; and (3) avoids the need for more extensive open neck procedures. However, risks of KTP laser therapy are not negligible and strategies must be in place to minimize the occurrence of complications.
