RESUMO
OBJECTIVES: The purpose of this study was to determine the best time to assess middle ear status with tympanometry for tympanometric instrument validation. The research question addressed three logical times for tympanometric reading prior to myringotomy. METHODS: Fifty-one children, ranging in age from nine months to 10 years, were recruited for this investigation. Participants underwent inhalant anesthesia for myringotomy and grommet placement with or without adenoidectomy and/or tonsillectomy. Tympanometry data was analyzed across three time periods. RESULTS: Findings indicated that tympanometric readings prior to anesthesia produced the most accurate results. CONCLUSIONS: Implicated in findings, in order to ensure that tympanometric instruments are reliable, typanometric measurements should be taken prior to the administration of any anesthesia.

The incidence and prevalence of recurrent respiratory papillomatosis (RRP) for children aged <18 years were estimated in 2 US cities, Atlanta and Seattle, in 1996. All otolaryngologists in a 24-county area in metropolitan Atlanta (101 physicians) and an 8-county area in metropolitan Seattle (139 physicians) agreed to participate in the study. Medical record chart abstraction was performed only for children with documented current residence in the study area (21 patients in Atlanta and 14 patients in Seattle). The incidence rate for juvenile RRP was 1.11/100,000 population in Atlanta and 0.36/100, 000 in Seattle. The prevalence rate was 2.59/100,000 population in Atlanta and 1.69/100,000 in Seattle. In neither city did prevalences differ significantly when stratified by sex or race. Extrapolation of these estimates to the US population suggests that 80-1500 incident cases and 700-3000 prevalent cases of juvenile RRP will occur in the United States during 1999.

OBJECTIVES: Review the clinical differences between nasopharyngeal (NP) true teratomas and dermoids, with the addition of a case series to the literature. Additionally, review the impact of prenatal diagnosis on the management and outcome of these lesions. STUDY DESIGN: Retrospective review of cases from the Children's Hospital Medical Center (Seattle, WA) and Madigan Army Medical Center (Tacoma, WA) with the histopathologic diagnosis of nasopharyngeal teratoma or dermoid. Review of medical literature for cases reported since 1977, when prenatal diagnosis of these lesions was first reported. Only tumors of the nasopharynx were considered. METHODS: Charts and pertinent literature were reviewed and data presented with respect to age at diagnosis, signs and symptoms, perinatal diagnosis and management, preoperative evaluation, surgical treatment, and outcome. RESULTS: The majority of lesions were diagnosed at birth, with the most common presenting symptom being respiratory distress. Teratomas had a higher incidence of maternal polyhydramnios, preterm birth, need for emergent airway management, and associated congenital abnormalities. Complete surgical excision remains the treatment of choice. Recurrences were rare, occurring only in the teratoma group. Prenatal diagnosis did not have a significant impact on the diagnosis and treatment of these lesions in our review. CONCLUSIONS: Inconsistent use of a standard classification system has made differentiating between NP teratomas and dermoids difficult, although the clinical implications can be critical. NP teratomas have a higher incidence of preterm birth, neonatal airway distress, associated congenital abnormalities, need for more extensive surgical procedures, and recurrence. Prenatal diagnosis has made little impact on the overall diagnosis and treatment of these lesions.

BACKGROUND: The objective benefits of tympanostomy tubes for otitis media are well established, but the subjective impact of surgery on child quality of life (QOL) has not been systematically studied. OBJECTIVES: To determine the subjective impact of tympanostomy tubes on child QOL, and to compare the variability in QOL before surgery with that observed after surgery. DESIGN: Prospective, observational, before-and-after trial. SETTING: Fourteen referral-based pediatric otolaryngology practices in the United States. PATIENTS: Consecutive (64%) and convenience (36%) sample of 248 children (median age, 1.4 years) with otitis media scheduled for bilateral tympanostomy tube placement as an isolated surgical procedure. INTERVENTION: Tympanostomy tubes were inserted as part of routine clinical care. Validated measures of QOL (OM-6 survey), satisfaction with health care decision (Satisfaction With Decision Scale), and satisfaction with office visit; surveys were completed at baseline (visit 1), at surgery (visit 2), and after surgery (visit 3). MAIN OUTCOME MEASURES: Short-term changes in QOL before surgery (visit 1 to visit 2) and after surgery (visit 2 to visit 3). RESULTS: Changes in QOL before surgery were mostly trivial, and were smaller than changes observed after surgery (P<.001). Large, moderate, and small improvements in QOL occurred after surgery in 56%, 15%, and 8% of children, respectively. Physical symptoms, caregiver concerns, emotional distress, and hearing loss were most improved, but significant changes were also seen for activity limitations and speech impairment. Trivial changes occurred in 17% of children, and 4% had poorer QOL. Predictors of poorer QOL were otorrhea 3 or more days (10% of variance) and decreased satisfaction with surgical decision (3% of variance). Hearing status, child age, type of otitis media (recurrent vs chronic), and office visit satisfaction were unrelated to outcome. CONCLUSIONS: Tympanostomy tubes produce large short-term improvements in QOL for most children. The best outcomes occur when postoperative otorrhea is absent or minimal, and when parents are satisfied with their initial decision to have surgery. Further research is needed to document the long-term impact of tubes on child QOL.

Allergic fungal rhinosinusitis (AFRS) has a worldwide distribution. This survey of 20 otolaryngologic practices throughout the United States confirmed a variation in the frequency of AFRS relative to endoscopic sinus procedures performed for all other diagnoses. The highest incidence occurred in Memphis, Tennessee at 23%, with three other southern practices reporting a frequency of at least 10%. In the northern locations the frequency ranged from 0 to 4%. No correlation with mould counts was demonstrated, possibly because of incomplete mould data relative to most of the surgical locations.

Controversy continues over whether allergic fungal sinusitis represents a true allergy, an infection, or a point somewhere along a spectrum between allergy and infection. The present study describes two experiments that add weight to the argument that allergic fungal sinusitis (AFS) is truly an immunologically mediated hypersensitivity and not a form of infection. In the first experiment, eight patients with Bipolaris culture-positive AFS were prospectively evaluated with Bipolaris antigen skin testing and with inhibition radioallergosorbent (RAST) and enzyme-linked immunosorbent assay (ELISA) for Bipolaris-specific IgE and IgG antibodies. The Bipolaris AFS cases were compared with 10 control patients with no history of AFS. All eight AFS cases demonstrated positive skin testing to Bipolaris and in addition, all tested positive by RAST and ELISA for IgE and IgG Bipolaris antibodies, respectively. In the control group one patient had a positive skin test, ELISA, and RAST and one additional patient had a positive ELISA only. Good correlation was noted between skin test, RAST, and ELISA results. In the second experiment, sinus mucosa from 14 AFS patients and 10 control patients with other forms of surgical sinus disease was analyzed by immunohistocytochemistry for the eosinophilic inflammatory mediators major basic protein (MBP) and eosinophil derived neurotoxin (EDN) and the neutrophil mediator neutrophil elastase. All AFS cases demonstrated evidence of eosinophilic mediator release, and MBP and EDN predominated over neutrophil elastase. In the control group eosinophil and neutrophil mediator release in sinus mucosa was equal. The two experiments support the concept that AFS is an antigen-triggered, IgE- and IgG-mediated hypersensitivity response with a late-phase inflammatory reaction involving release of eosinophilic mediators.

Fourth branchial cleft sinuses are rare, and the nature of their origin is controversial. Clinical presentation is varied because they may present as asymptomatic neck masses, recurrent neck abscesses, or suppurative thyroiditis. We describe herein 7 children who presented with abscesses on the left side of their necks, 3 of whom had abscesses that involved the thyroid gland. Direct laryngoscopy revealed that all 7 children had a sinus tract opening into the apex of the piriform sinus. Endoscopic obliteration of this tract was achieved using an insulated electrocautery probe either when the abscess was initially incised and drained or 4 to 6 weeks later. All 7 children recovered uneventfully. Four of the 7 children were followed up for more than 18 months without recurrence.

OBJECTIVE: To determine risk factors predictive of outcomes to aid in the cost-effective preoperative evaluation and postoperative management of patients who are undergoing tonsillectomy and adenoidectomy for obstructed breathing during sleep. DESIGN: A historical cohort study with a nested case-control analysis that examined risk factors associated with postoperative respiratory complications. SETTING: Children's Medical Center of Dallas, Dallas, Tex, which is a pediatric referral hospital for secondary and tertiary pediatric care with both private and university-appointed physicians. PATIENTS: A convenience sample of 355 patients who were undergoing tonsillectomy and adenoidectomy for obstructed breathing during sleep throughout a 1-year period. INTERVENTION: None. MAIN OUTCOME MEASURE: The occurrence of postoperative complications, including airway obstruction, apneas with oxygen desaturations, airway interventions (e.g., endotracheal intubation), or administration of supplemental oxygen, as they related to associated medical conditions (e.g., cerebral palsy or prematurity) and diagnostic tests (e.g., chest x-ray film and electrocardiogram). RESULTS: Five associated medical conditions (cerebral palsy; seizures; age, < or = 3 years; congenital heart disease; and prematurity) were identified as important predictors of a complicated postoperative course using stepwise logistic regression analysis. Those children with an abnormal chest x-ray film or electrocardiogram were also identified as having an associated medical condition that was predictive of postoperative complications. CONCLUSIONS: Children with 1 or more of the associated risk factors identified should be considered candidates for postoperative inpatient observation. A preoperative chest x-ray film and electrocardiogram were found to be of little predictive value, and they are probably not cost-effective screening tests for postoperative respiratory complications.

Previous studies examining middle ear pressure changes due to inhalant anesthesia, including nitrous oxide, have cited equivocal results. An investigation was performed to closely monitor changes in middle ear pressure during middle ear surgery. Baseline tympanometry was performed before anesthesia, and middle ear pressure was then documented in 1-min time intervals. A total of 97 subjects were studied; 51 received nitrous oxide and halothane, and 46 received halothane alone. Results indicate that nitrous oxide causes significantly greater pressure fluctuations than halothane alone. There were no effects for time of surgery, type of fluid, or baseline. Pressure fluctuation was attributed to eustachian tube function. Case studies are presented to demonstrate subject variability, and suggestions for validation study procedures are presented.

The incidence of post-extubation stridor (PES) in a pediatric intensive care unit (PICU) and the need for reintubation is not known. Predictors of success on a subsequent extubation attempt and the efficacy of dexamethasone treatment prior to a subsequent extubation attempt are not established. In a prospective randomized double blind-controlled study in two PICU's in a university children's hospital setting, of 5,566 admissions over 35-months, we identified 32 patients who failed primary extubation and were reintubated for PES. Twenty-six patients were enrolled in the study and three subsequently excluded. Twelve were randomized to receive dexamethasone and 11 received sodium chloride placebo. Fifteen patients succeeded study extubation and eight failed. Of those receiving dexamethasone, nine patients succeeded and three failed. Of those receiving placebo, six patients succeeded and five failed. There was a poor correlation between anatomical abnormalities of the airway and failure of study extubation. Extubation failure was better correlated with neurologic impairment in the patients. We present a stridor score and demonstrate that it is an excellent predictor of success versus failure for the study extubation. Dexamethasone pre-treatment did not reduce stridor score. We are unable to conclude if dexamethasone pre-treatment reduces extubation failure. We speculate that neurologic impairment leads to extubation failure in critically ill pediatric patients.

The objective of this study was to describe CT and MR findings in patients with allergic fungal sinusitis (AFS). CT and MR images were examined from 10 patients with histologically proven AFS. All patients demonstrated CT evidence of central sinus high attenuation and T2-weighted MR signal void corresponding to surgically proven areas of thick inspissated allergic mucin. AFS is a distinct clinical entity with a highly specific radiographic appearance based on CT and MRI.

Recommendations to withhold immunotherapy with fungal antigens from patients with allergic fungal sinusitis (AFS) have been based primarily on retrospectively reviewed, anecdotal case reports and theoretical considerations. A study that was approved by the investigational review board of our institution is ongoing in our department to administer immunotherapy with relevant fungal antigens to patients with histologically proven AFS. After 1 year, no instances of worsening of symptoms as a result of this therapy have been observed. Objective measurement of improvement has been difficult, but our initial clinical impression is that this treatment regimen has resulted in significant reduction in the reaccumulation of crusts and allergic mucin within the sinuses, has led to a reduction in the use of topical nasal steroids, and has made systemic steroid therapy unnecessary, thereby improving the quality of life of the patient. A further study of immunotherapy for patients with AFS is recommended, and suggestions for modification of the current protocol are presented.

Syringocystadenoma papilliferum (SCAP) is a rare benign skin tumor which clinically resembles papilloma. It is characterized by extensive papillary epithelial elements growing into the dermis. SCAP often presents at birth and most commonly in the head and neck. We present a case of a newborn with SCAP of the right ear and neck, treated with CO2 laser excision because the lesion was poorly amenable to excision and closure or grafting. Two CO2 laser procedures have produced a good result and reasonable cosmesis. CO2 laser excision of SCAP of the head and neck is a clinical treatment option in anatomic areas unfavorable to excision and grafting.
