Two-Year Outcomes After Pediatric In-Office Tympanostomy Using Lidocaine/Epinephrine Iontophoresis and an Automated Tube Delivery System.

OBJECTIVE: Evaluate 2-year outcomes after lidocaine/epinephrine iontophoresis and tympanostomy using an automated tube delivery system for pediatric tube placement in-office. STUDY DESIGN: Prospective, single-arm. SETTING: Eighteen otolaryngology practices. METHODS: Children age 6 months to 12 years indicated for tympanostomy were enrolled between October 2017 and February 2019. Local anesthesia of the tympanic membrane was achieved via lidocaine/epinephrine iontophoresis and tympanostomy was completed using an automated tube delivery system (the Tula® System). An additional Lead-In cohort of patients underwent tube placement in the operating room (OR) under general anesthesia using only the tube delivery system. Patients were followed for 2 years or until tube extrusion, whichever occurred first. Otoscopy and tympanometry were performed at 3 weeks, and 6, 12, 18, and 24 months. Tube retention, patency, and safety were evaluated. RESULTS: Tubes were placed in-office for 269 patients (449 ears) and in the OR for 68 patients (131 ears) (mean age, 4.5 years). The median and mean times to tube extrusion for the combined OR and In-Office cohorts were 15.82 (95% confidence interval [CI]: 15.41-19.05) and 16.79 (95% CI: 16.16-17.42) months, respectively. Sequelae included ongoing perforation for 1.9% of ears (11/580) and medial tube displacement for 0.2% (1/580) observed at 18 months. Over a mean follow-up of 14.3 months, 30.3% (176/580) of ears had otorrhea and 14.3% (83/580) had occluded tubes. CONCLUSION: In-office pediatric tympanostomy using lidocaine/epinephrine iontophoresis and automated tube delivery results in tube retention within the ranges described for similar grommet-type tubes and complication rates consistent with traditional tube placement in the OR.

In RRP, serologic response to HPV is frequently absent and slow to develop.

BACKGROUND: Recurrent respiratory papillomatosis (RRP) is characterized by repeated formation of papillomas in the respiratory tract and is caused by human papillomavirus (HPV) types 6 and 11. Women with genital HPV infection are slow to develop weak humoral immunity, but respond robustly to the HPV vaccine. We wondered if people with RRP had a similar immune response. METHODS: A convenience cross-sectional sample of patients with RRP were recruited into one of four groups: 1) adults and adolescents with active RRP, 2) children with active RRP, 3) RRP patients who had undergone HPV vaccination prior to enrollment and, 4) people with RRP who were in remission. Anti-HPV6 and HPV11 serology was determined by cLIA on a single blood draw. RESULTS: Of the 70 subjects enrolled, 36, 16, 8, and 10, were in groups 1, 2, 3, and 4, respectively. 47% of participants aged >11 years and 81% aged ≤11 years possessed no antibodies against HPV6 or HPV11 (ie. double seronegative). 61% of patients in remission were double seronegative. All participants who had received HPV vaccine previously were seropositive to at least one of these low risk HPV types (ie none of them were double seronegative). Among patients who had active RRP and never had HPV vaccination (n = 52) there was an association between duration of symptoms and seropositivity. Of those who were seropositive, the geometric mean duration of symptoms was 11 years compared to 4.7 years for those who were seronegative (p = 0.001). CONCLUSION: People with RRP are capable of developing a humoral response to HPV6 and HPV11. That response appears to be robust when initiated by the HPV vaccine, but either nonexistent or slow to develop in response to infection. Most in remission do not have demonstrable antibody levels against HPV6 or HPV11.

In-Office Tympanostomy Tube Placement in Children Using Iontophoresis and Automated Tube Delivery.

OBJECTIVES/HYPOTHESIS: Evaluate technical success, tolerability, and safety of lidocaine iontophoresis and tympanostomy tube placement for children in an office setting. STUDY DESIGN: Prospective individual cohort study. METHODS: This prospective multicenter study evaluated in-office tube placement in children ages 6 months through 12 years of age. Anesthesia was achieved via lidocaine/epinephrine iontophoresis. Tube placement was conducted using an integrated and automated myringotomy and tube delivery system. Anxiolytics, sedation, and papoose board were not used. Technical success and safety were evaluated. Patients 5 to 12 years old self-reported tube placement pain using the Faces Pain Scale-Revised (FPS-R) instrument, which ranges from 0 (no pain) to 10 (very much pain). RESULTS: Children were enrolled into three cohorts with 68, 47, and 222 children in the Operating Room (OR) Lead-In, Office Lead-In, and Pivotal cohorts, respectively. In the Pivotal cohort, there were 120 and 102 children in the <5 and 5- to 12-year-old age groups, respectively, with a mean age of 2.3 and 7.6 years, respectively. Bilateral tube placement was indicated for 94.2% of children <5 and 88.2% of children 5 to 12 years old. Tubes were successfully placed in all indicated ears in 85.8% (103/120) of children <5 and 89.2% (91/102) of children 5 to 12 years old. Mean FPS-R score was 3.30 (standard deviation [SD] = 3.39) for tube placement and 1.69 (SD = 2.43) at 5 minutes postprocedure. There were no serious adverse events. Nonserious adverse events occurred at rates similar to standard tympanostomy procedures. CONCLUSIONS: In-office tube placement in selected patients can be successfully achieved without requiring sedatives, anxiolytics, or papoose restraints via lidocaine iontophoresis local anesthesia and an automated myringotomy and tube delivery system. LEVEL OF EVIDENCE: 2b Laryngoscope, 130:S1-S9, 2020.

Age at diagnosis, but not HPV type, is strongly associated with clinical course in recurrent respiratory papillomatosis.

BACKGROUND: Recurrent Respiratory Papillomatosis (RRP) is a rare disease characterized by the growth of papillomas in the airway and especially the larynx. The clinical course is highly variable among individuals and there is poor understanding of the factors that drive an aggressive vs an indolent course. METHODS: A convenience cohort of 339 affected subjects with papillomas positive for only HPV6 or HPV11 and clinical course data available for 1 year or more, from a large multicenter international study were included. Exploratory data analysis was conducted followed by inferential analyses with frequentist and Bayesian statistics. RESULTS: We examined 339 subjects: 82% were diagnosed prior to the age of 18 years, 65% were infected with HPV6, and 69% had an aggressive clinical course. When comparing age at diagnosis with clinical course, the probability of aggressiveness is high for children under five years of age then drops rapidly. For patients diagnosed after the age of 10 years, an indolent course is more common. After accounting for confounding between HPV11 and young age, HPV type was minimally associated with aggressiveness. Fast and Frugal Trees (FFTs) were utilized to determine which algorithms yield the highest accuracy to classify patients as having an indolent or aggressive clinical course and consistently created a branch for diagnostic age at ~5 years old. There was no reliable strong association between clinical course and socioeconomic or parental factors. CONCLUSION: In the largest cohort of its type, we have identified a critical age at diagnosis which demarcates a more aggressive from less aggressive clinical course.

Application of a standardized screening protocol for diagnosis of invasive mold infections in children with hematologic malignancies.

PURPOSE: This study describes a standardized screening protocol for diagnosis of invasive mold infections in pediatric oncology patients with neutropenia and prolonged or recurrent fever. METHODS: A retrospective chart review was performed of children receiving intensive chemotherapy for hematologic malignancies who developed invasive mold infections from 2004 to 2011. Characteristics and outcomes were compared before and after implementation of the screening protocol in November 2006. The screen includes direct nasal endoscopy performed at the bedside by an otorhinolaryngologist, noncontrast computed tomography (CT) of the chest, and abdominal ultrasound in patients with neutropenia and prolonged or recurrent fever. RESULTS: Fifty patients had proven, probable, or possible invasive mold infections. Before routine use of direct nasal endoscopy, invasive nasosinal disease was detected in 5 of 19 patients (26 %) and all had a compatible clinical presentation. Thirteen of 31 patients (42 %) in the post-screen group had nasosinal disease, and fever was the only sign for 8 patients (62 %). Twenty-four patients with nasosinal disease had a sinus CT, and radiologic findings of bony erosion or peri-sinus invasion were never detected. Eight of 19 patients in the pre-screen group died from mold infection (42.1 %) versus 4 of 31 (12.9 %) in the post-screen group (p = 0.04). CONCLUSIONS: A screening protocol including direct nasal endoscopy, noncontrast chest CT, and abdominal ultrasound was effective in detecting invasive mold infections in at-risk patients. Nasosinal involvement often occurs before specific symptoms develop, and sinus CTs are insensitive and nonspecific. Bedside nasal endoscopy precludes radiation exposure associated with sinus CT and was associated with decrease in mold-related mortality, likely due to earlier diagnosis and initiation of appropriate antifungal therapy.

An unusual tongue base mass in an infant: Tongue base sialolipoma.

Sialolipoma is a rare tumor that occurs in the head and neck. We present a case arising from a minor salivary gland in an infant. The 6-month-old infant presented with difficulty swallowing, frequent reflux, and snoring that had been worsening several weeks before presentation. Physical examination showed a large mass arising from the tongue base. The patient was taken to the operating room for transoral removal of a presumed cyst. Histologic examination of the lesion showed a well-circumscribed lesion composed of lobules of mature adipose tissue and nodules of entrapped, non-neoplastic acini and ductules separated by thin, fibrous septae, consistent with a sialolipoma. To the best of our knowledge, this is the first reported case of a sialolipoma at the tongue base in a child. The patient has had no evidence of recurrence at 1 year of follow-up.

Endoscopic cauterization of congenital pyriform fossa sinus tracts: an 18-year experience.

IMPORTANCE: Congenital pyriform fossa sinus tracts predispose to neck masses and neck abscesses in pediatric and occasionally adult patients. Traditional management involves open excision with substantial potential morbidity. Endoscopic management allows an alternative, less morbid treatment approach. OBJECTIVE: To evaluate the long-term effectiveness of endoscopic cauterization as definitive treatment for pyriform fossa sinus tracts. DESIGN, SETTING, AND PATIENTS: Retrospective review of the medical records of 23 children (aged 7 months to 14 years) with pyriform fossa sinus tracts treated with endoscopic cauterization between 1995 and 2013 at a tertiary care children's hospital. INTERVENTION: Endoscopic electrocauterization of pyriform fossa sinus tract opening. MAIN OUTCOMES AND MEASURES: Recurrence of symptoms after endoscopic treatment. RESULTS: Twenty-one of 23 patients experienced no recurrence after their first endoscopic electrocauterization of the sinus tract. The 2 patients with recurrence experienced symptoms within 1 month of cauterization and were treated with either open excision or recauterization. Endoscopic cauterization was able to definitively treat 9 patients whose treatments with incision and drainage or open excision had failed. Mean (range) follow-up for the 15 patients with follow-up was 7.4 (0.10-14.2) years. No procedure-related morbidity was reported. CONCLUSIONS AND RELEVANCE: Endoscopic cauterization seems to be an effective and potentially permanent treatment for congenital pyriform fossa sinus tracts.

Management of cervicofacial nontuberculous lymphadenitis in children.

PURPOSE OF REVIEW: To review the body of literature on the treatment options for nontuberculous cervicofacial lymphadenitis in children, focusing on the most recent reports describing outcomes utilizing either observation alone, medical therapy or various forms of surgical intervention. RECENT FINDINGS: Large studies have defined the time course of the disease and the safety and efficacy in treating nontuberculosis cervicofacial lymphadenitis with a wait-and-see approach. SUMMARY: Nontuberculosis cervicofacial lymphadenitis is a disease with several stages that provides for various treatment options. All treatment regimens--wait-and-see approach, medical therapy, and surgical excision--have their risks and benefits. The current body of literature allows the otolaryngologist an assortment of treatment choices that permits him to tailor the treatment with an individualized approach for each family's preferences.

Sutureless vs sutured posterior costal cartilage grafting in laryngotracheal reconstruction in children.

OBJECTIVE: To compare the postoperative course, complication rate, and decannulation rate in children who underwent either sutureless or sutured posterior costal cartilage grafting during laryngotracheal reconstruction (LTR). DESIGN: Retrospective chart review. SETTING: Tertiary care children's medical center. PATIENTS: The study included children who required posterior costal cartilage grafting when undergoing LTR for subglottic stenosis between the years of 2000 and 2009 by the senior author (J.E.M.) and who had adequate records for review. MAIN OUTCOME MEASURES: Postoperative complications, including the incidence of graft prolapse, restenosis or reobstruction requiring surgical intervention, and decannulation rate. RESULTS: Forty-nine children who underwent 52 procedures met the inclusion criteria for this study. All patients had grade III acquired subglottic stenosis and underwent double-staged LTR. Twenty procedures were performed with a sutureless posterior graft, and 32 were performed with suture placement. None of the 20 procedures that were performed with a sutureless graft had prolapse of the graft into the airway compared with 2 of 32 prolapsed posterior grafts (6%) that were sutured (P = .52). Eleven of 20 children (55%) with sutureless posterior grafts compared with 24 of 32 children (75%) who underwent sutured posterior grafts required endoscopic surgical intervention for restenosis or reobstruction (P = .22). Decannulation was achieved in 19 of 20 sutureless cases (95%) and in 28 of 30 cases (93%) in which sutures were placed (P = .56) after a single LTR and necessary endoscopic interventions occurring at 6.3 months and 4.9 months, respectfully (P = .42). CONCLUSION: Sutureless posterior costal cartilage grafting in children with acquired grade III subglottic stenosis is an equally effective and secure technique compared with sutured posterior grafting during double-staged LTR.

Endoscopic management of subglottic stenosis.

OBJECTIVES: Determine the effectiveness of endoscopic surgical treatment of subglottic stenosis (SGS) in children as a primary surgical modality to prevent laryngotracheal reconstruction (LTR) and as treatment for restenosis following primary LTR to prevent revision LTR. PATIENTS: Children undergoing various endoscopic surgical treatments from 1989 to 2006 for SGS. RESULTS: The number of children and success rates per grade of SGS and the number of procedures required to produce a successful result in 29 children initially managed endoscopically included grade I, three of three (100%), 1.3 procedures; grade II, eight of nine (88%), 2.6 procedures; and grade III, 13 of 17 (76%), 3.5 procedures. Of 102 patients undergoing open LTR, 56 of 102 required endoscopic interventions and 41 of 56 (73%) children were treated successfully. CONCLUSION: Endoscopic intervention can be used to manage SGS either as a primary intervention or to treat reobstruction and restenosis following an open reconstructive procedure. Success rates decline as the severity of stenosis increases.

Evaluation of pediatric sensorineural hearing loss with magnetic resonance imaging.

OBJECTIVE: To evaluate the incidence and type of intracranial and inner ear abnormalities in children with sensorineural hearing loss (SNHL) identified with magnetic resonance imaging (MRI) and stratified by the degree and type of SNHL. DESIGN: Retrospective review of medical records and MRIs. SETTING: Tertiary care children's hospital. PATIENTS: A total of 227 children aged 1 month to 17 years (mean age, 5.3 years; male to female ratio, 1:1) with a diagnosis of SNHL underwent MRI from June 1,1996, to June 1, 2002. Of these children, 170 had clinical information available and technically adequate MRIs and were included in the study. INTERVENTION: Magnetic resonance imaging. MAIN OUTCOME MEASURE: Identification of an abnormality of the intracranial contents, inner ear, and cochlear nerve. RESULTS: Of the 170 children, 101 (59%) had bilateral SNHL and 69 (41%) had unilateral SNHL, comprising 271 ears with SNHL. Abnormalities of the inner ear were found in 108 ears (40%) with 87 (32%) having abnormalities of the cochlea, which were considered mild in 63 (23%) and moderate to severe in 24 (9%). Forty-nine of 271 ears (18%) with SNHL demonstrated an either absent (26/49 [53%]) or deficient (23/49 [47%]) cochlear nerve. Ears with severe and profound SNHL had more abnormalities than ears with mild and moderate SNHL (66/138 [48%] vs 23/80 [29%]; P = .006), and children having ears with unilateral moderate, severe, or profound SNHL had more inner ear abnormalities than children with bilateral moderate, severe, or profound SNHL (28/45 [62%] vs 54/144 [38%]; P = .004). CONCLUSIONS: The overall incidence of inner ear abnormalities in ears of children with SNHL evaluated by MRI is 40%. The most common abnormalities seen were an abnormal cochlea and abnormal cochlear nerve. Children with severe and profound SNHL have a greater percentage of inner ear anomalies than children with mild or moderate SNHL. Children with unilateral hearing loss have a greater percentage of inner ear anomalies than children with bilateral SNHL.

Age of child, more than HPV type, is associated with clinical course in recurrent respiratory papillomatosis.

BACKGROUND: RRP is a devastating disease in which papillomas in the airway cause hoarseness and breathing difficulty. The disease is caused by human papillomavirus (HPV) 6 or 11 and is very variable. Patients undergo multiple surgeries to maintain a patent airway and in order to communicate vocally. Several small studies have been published in which most have noted that HPV 11 is associated with a more aggressive course. METHODOLOGY/PRINCIPAL FINDINGS: Papilloma biopsies were taken from patients undergoing surgical treatment of RRP and were subjected to HPV typing. 118 patients with juvenile-onset RRP with at least 1 year of clinical data and infected with a single HPV type were analyzed. HPV 11 was encountered in 40% of the patients. By our definition, most of the patients in the sample (81%) had run an aggressive course. The odds of a patient with HPV 11 running an aggressive course were 3.9 times higher than that of patients with HPV 6 (Fisher's exact p = 0.017). However, clinical course was more closely associated with age of the patient (at diagnosis and at the time of the current surgery) than with HPV type. Patients with HPV 11 were diagnosed at a younger age (2.4y) than were those with HPV 6 (3.4y) (p = 0.014). Both by multiple linear regression and by multiple logistic regression HPV type was only weakly associated with metrics of disease course when simultaneously accounting for age. CONCLUSIONS/SIGNIFICANCE ABSTRACT: The course of RRP is variable and a quarter of the variability can be accounted for by the age of the patient. HPV 11 is more closely associated with a younger age at diagnosis than it is associated with an aggressive clinical course. These data suggest that there are factors other than HPV type and age of the patient that determine disease course.

Four mutations in Epidermodysplasia verruciformis 1 (EVER1) gene are not contributors to susceptibility in RRP.

OBJECTIVE: Epidermodysplasia verruciformis is a skin disease characterized by abnormal susceptibility to human papilloma viruses. Recently four mutations in the Epidermodysplasia verruciformis 1 gene (EVER1, also known as TMC6) have been associated with the disease. Because of the phenotypic similarity between Epidermodysplasia verruciformis and recurrent respiratory papillomatosis, we decided to investigate whether any of these mutations accounts for the susceptibility to human papilloma viruses in subjects with recurrent respiratory papillomatosis (RRP). METHODS: Allele-specific PCR and restriction fragment length polymorphisms (RFLPs) were employed for genotyping a cohort of 101 patients with recurrent respiratory papillomatosis. RESULTS: None of these four mutations were found in the studied subjects. CONCLUSION: The absence of these mutations in RRP patients might indicate that EVER 1 alleles are not associated with susceptibility to RRP, or that other, as yet unidentified, mutations in the Epidermodysplasia verruciformis 1 gene, might account for the susceptibility to RRP.

Antibiotic therapy for nontuberculous mycobacterial cervicofacial lymphadenitis.

OBJECTIVES/HYPOTHESIS: To evaluate the efficacy of antibiotic treatment of nontuberculous mycobacterial (NTM) cervicofacial lymphadenitis, both as an alternative and as adjuvant to surgical excision. STUDY DESIGN: Retrospective chart review of pediatric patients with NTM cervicofacial lymphadenitis treated from January 1993 to November 2003 at an academic tertiary care children's hospital. METHODS: Fifty-five patients (age range, 15 mo-16 y) with the diagnosis of NTM cervicofacial lymphadenitis by fine-needle aspiration biopsy that had 1) lymph node culture positive for an atypical mycobacteria, 2) histological findings consistent with mycobacterial infection (granulomas) with negative bartonella serological titers, 3) histological stain positive for the presence of acid-fast bacillus in the absence of tuberculous infection, or 4) positive Mantoux tuberculin skin test result with a negative finding on polymerase chain reaction for tuberculous mycobacteria. Clinical response was defined as complete or partial resolution of skin changes and palpable lymphadenopathy in response to antibiotic therapy consisting of macrolide therapy alone or in combination with other anti-mycobacterial pharmaceuticals. RESULTS: Of the 55 children studied, 45 of 55 (82%) with both single and multiple lesions underwent a trial of medical therapy, and 30 of 45 lesions (67%) ranging in size from 1 x 1 to 6 x 5 cm achieved resolution without surgical excision. Of the other 15 patients treated initially with medical therapy, 6 of 15 (40%) responded well to a course of antibiotic therapy before undergoing surgical excision, and 7 of 15 (47%) patients were nonresponsive to antibiotic therapy and required surgical excision to resolve the neck mass. The remaining 2 of 15 patients (13%) proceeded to surgery only after a course of antibiotics of 3 weeks or less. Ten of the 55 patients (18%) underwent surgical excision initially, with 5 of 10 patients (50%) receiving postoperative antibiotics for treatment of residual disease or prevention of recurrence. CONCLUSION: Some NTM cervicofacial lymphadenitis infections appear to respond to medical therapy alone. A trial of antibiotic therapy might be considered in patients with NTM cervicofacial lymphadenitis before surgical excision or as an adjuvant to surgical excision.

Intravenous antibiotic therapy for deep neck abscesses defined by computed tomography.

OBJECTIVE: To determine the effectiveness of using intravenous antibiotics alone to treat clinically stable children with clearly defined deep neck abscesses diagnosed by contrast-enhanced computed tomography (CT). DESIGN: Retrospective chart and CT scan review. SETTING: Tertiary care children's hospital. PATIENTS: The study comprised clinically stable pediatric patients who presented with signs and symptoms of a deep neck infection and who had CT scans demonstrating an abscess in the parapharyngeal space, retropharyngeal space, or both that included (1) a well-formed ring enhancement around a nonenhancing density consistent with fluid and (2) a size greater than 1 cm in every dimension. MAIN OUTCOME MEASURES: Clinical resolution of the signs and symptoms of the deep neck abscess after treatment with intravenous antibiotics. RESULTS: Over a 22-month period (May 1999 to March 2001), 11 children ranging in age from 4 months to 16(1/2) years who had contrast-enhanced CT evidence of deep neck abscess and no clinical evidence of severe symptoms or significant airway compromise were initially treated with intravenous antibiotics. Ten (91%) of the 11 children responded to intravenous antibiotic therapy as their only treatment. All 10 responders began to improve clinically by 48 hours. The symptoms resolved in 5 children by treatment day 3. Five to 8 days of treatment were required to completely resolve the symptoms in the other 5 patients. The 1 child who did not respond to intravenous antibiotic therapy underwent surgical drainage of her deep neck abscess within 12 hours of admission, with purulence discovered at the time of surgery. CONCLUSION: In a select number of clinically stable children, deep neck abscesses diagnosed on contrast-enhanced CT scans using strict radiographic criteria can be effectively treated with intravenous antibiotics alone.

Laryngeal duplication cyst.

Benign congenital laryngeal cysts are rare. Infants and children with these lesions can present with chronic or intermittent airway obstructive symptoms, hoarseness, aspiration, chronic cough, or failure to thrive. The most common congenital laryngeal cysts include saccular cysts, laryngoceles, and ductal cysts. Other more unusual laryngeal lesions, such as hamartomas, choristomas, and teratomas, can also present with these symptoms. We describe a unique congenital cyst that arose in continuity with the larynx in a child with hoarseness and intermittent stridor. The features of this lesion are similar to those of bronchogenic duplication cysts of the trachea, but with histopathological features of the larynx.

Clinical presentation of allergic fungal sinusitis in children.

OBJECTIVE: To compare the differences in the clinical and radiographic presentation of allergic fungal sinusitis in children and adults. STUDY DESIGN: Retrospective chart and computed tomography review. METHODS: The settings included a tertiary care children's hospital, adult academic private hospital, and academic affiliated county hospital. All patients with documented allergic fungal sinusitis who underwent computed tomography evaluation and had surgical treatment of their disease from 1988 to 1999 were included in the study. In total, 151 patients aged 5 to 75 years; 44 of these patients were less than or equal to 17 years of age (children) and 107 were greater than 17 years of age (adults). Main outcome measures included 1) the presence of obvious bony facial abnormalities on presentation, 2) bilateral or unilateral sinus disease on presentation, 3) the presence of asymmetrical disease on presentation, 4) the presence of bony extension on computed tomography scan, and 5) type of fungus present. RESULTS: Fifteen of 36 (42%) pediatric patients and 10 of 103 (10%) adult patients had obvious alteration of their facial skeleton (proptosis, telecanthus, or malar flattening) on presentation (P <.05). Proptosis was the most common facial abnormality in both groups and was seen more often in children (8 of 36 [22%]) than in adults (9 of 103 [9%]) (P <.05). Twenty-eight of 40 (70%) pediatric patients and 37 of 100 (37%) adult patients presented with unilateral sinus disease (P <.05). Thirty-five of 40 (88%) pediatric patients and 58 of 100 (58%) adults presented with asymmetrical disease (P <.05). Computed tomography scans showed that 10 of 40 (25%) pediatric patients and 23 of 100 (23%) adult patients had bony erosion with extension of disease into surrounding structures (P >.05). Cultures from both adults and children showed mainly Bipolaris and Curvilaria species in equal amounts (P >.05). Adults had a greater incidence of Aspergillus species. CONCLUSIONS: Presentation in pediatric patients with allergic fungal sinusitis is different from that in adults, with children having obvious abnormalities of their facial skeleton, unilateral sinus disease, and asymmetrical disease more often. Findings on computed tomography scan show an equal amount of bony erosion with extension of disease. The types of fungus cultured in the sinus cavities are similar in both groups.

Major and minor temporal bone abnormalities in children with and without congenital sensorineural hearing loss.

OBJECTIVE: To determine the extent of correlation between sensorineural hearing loss (SNHL) and abnormal temporal bone anatomy in children. DESIGN: Axial and coronal high-resolution computed tomographic scans of the temporal bones of 247 children (494 ears) aged 2 months to 15 years with and without SNHL were blindly reviewed. The presence or absence of mild or severe cochlear dysplasias, vestibular dysplasias, and an enlarged vestibular aqueduct (VA) were recorded. The width of the VA was measured. The height, width, and length of the internal auditory canal (IAC) were measured, and abnormalities were described as narrow, widened, or bulbous. Clinical information was then reviewed to determine the presence or absence of a congenital syndrome and/or SNHL, and historical factors that might be responsible for SNHL. MAIN OUTCOME MEASURE: The relationship between radiographic findings and SNHL. RESULTS: One hundred thirteen patients (185 ears) had SNHL. Significant abnormal temporal bone anatomy in children with vs without SNHL included major cochlear and vestibular dysplasias (17% vs 0%; P<.001), enlarged VA (>2 mm) (5% vs 0%; P<.001), and narrow IAC (< or =2 mm) (4% vs 1%; P=.03). The average IAC width (4.85 vs 5.02 mm), height (4.39 vs 4.62 mm), and length (11.22 vs 11.44 mm) were not statistically different between children with vs without SNHL. In children with vs without SNHL, neither a widened (0.5% vs 3.6%) nor a bulbous (9% vs 8%) IAC was seen more often in children with SNHL. In ears with SNHL, the presence of a congenital syndrome significantly increased the risk of cochlear and vestibular abnormalities of the temporal bone (45% vs 14%; P<.001), including IAC abnormalities (30% vs 2%;P<.001), which overall were more commonly seen in children with (20%) vs without (3%) a congenital syndrome regardless of the presence of SNHL. No children with an enlarged VA had a congenital syndrome. CONCLUSIONS: Well-established temporal bone abnormalities such as cochlear and vestibular abnormalities and a grossly enlarged vestibular aqueduct are significantly found in children with SNHL. A narrow IAC is found more often in children with vs without SNHL. No significant correlation is found between SNHL and radiographic findings of a widened or bulbous IAC. In children with a congenital syndrome, more IAC abnormalities were seen, regardless of the presence of SNHL. In children with SNHL, the presence of a congenital syndrome increases the likelihood of a cochlear or vestibular abnormality.
