Validation of the Maxillary Sinus Roof as a Landmark for Navigating the Pediatric Skull Base.

OBJECTIVE: To define a new anatomic relationship in pediatric sinus surgery, assessing the maxillary roof as a constant safe landmark to avoid skull base injury in the pediatric population. STUDY DESIGN: Retrospective analysis. SETTING: Tertiary care children hospital. SUBJECTS AND METHODS: A retrospective analysis was performed of all computed tomography scans of the sinuses and facial bones at the emergency department of a tertiary children's hospital over the course of a year. Radiographic measurements included the lowest cribriform plate and planum sphenoidale (PS) heights, or posterior skull base when not yet pneumatized, as well as the highest maxillary roof height. The nasal floor was used for reference. Statistics were performed via Shapiro-Wilks test with a P-value of .05 indicating statistical significance. RESULTS: Three hundred and seven unique scans were reviewed (38.9% female; n = 122; P = .58). Age stratification was based on previously described sinus growth patterns. In all patients, the maximum maxillary height was inferior to the lowest measured cribriform lamella and PS (P < .001; CI, 98.5%-99%). Inter- and intrarater reliability and accuracy were verified through blinded review and re-review (ρ = .99 and .98 respectively, P ≤ .001). The validity of sole coronal measurements due to incomplete sagittal reformatting was also confirmed (ρ = 1.00, P ≤ .001). CONCLUSION: Despite variation in sinus growth and development in children, the current study demonstrated the validity of the maxillary sinus roof as a constant safe landmark in the pediatric population, offering a novel anatomic relationship for teaching safety in performing pediatric sinus surgery. LEVEL OF EVIDENCE: 4.

Health disparities in pediatric cochlear implantation: an audiologic perspective.

OBJECTIVES: A national survey of pediatric cochlear implantation (PCI) audiologists was conducted with three aims: (1) to determine if PCI audiologists perceive within their clinical practice a negative effect of low socioeconomic status (SES) on postimplant speech and language outcomes; (2) to understand their perceptions of the underlying factors leading to outcome disparities; and (3) to elicit suggestions for improving outcomes in disadvantaged populations. We hypothesized that audiologists would perceive reduced speech and language outcomes within their lower SES patient population, and that this noted disparity would be related to parental adherence (compliance) and access to habilitation. DESIGN: A survey containing 22 quantitative and open-ended questions was electronically mailed to a data base of 234 PCI audiologists. Forty-four percent (N = 103 of 234) responded to the survey, with the majority (98 of 103) answering all questions. Quantitative responses were analyzed using the Stata 9 statistical package with significance at p < 0.05. Qualitative responses were analyzed using standardized codebook and content analysis. Transcripts were read and coded for the main ideas expressed in each response. The codes were then analyzed for patterns and organized into subthemes that were then grouped into themes. RESULTS: Seventy-eight percent (N = 76 of 98) of respondents perceived an effect of SES on postimplant speech and language outcomes. Qualitative responses uniformly demonstrated audiologists' perception that lower SES patient populations were more likely to experience reduced speech and language outcomes. Two major themes emerged in audiologists' explanations of SES-related disparities: internal factors of parental influence (i.e., parental self-efficacy, adherence, and habilitation carryover), and external factors (i.e., inadequate therapy and lack of available resources). Three primary suggestions were offered for reducing the disparity: improvement in cochlear implant services (92%), increased emphasis on parental education and intervention (87%), and the development of stricter candidacy requirements (15%). CONCLUSIONS: This study offers evidence to show that PCI audiologists note an SES-related disparity in the field of PCI. Respondents suggest the need for a broad and culturally sensitive effort to both increase access to qualified healthcare professionals and develop approaches that will aid parents in the at-home habilitation process.

Multicenter Interrater Reliability in the Endoscopic Assessment of Velopharyngeal Function Using a Video Instruction Tool.

OBJECTIVE: Assess interrater agreement of endoscopic assessment of velopharyngeal (VP) function before and after viewing the video instruction tool (VIT). We hypothesized improvement in interrater agreement using the Golding-Kushner scale (GKS) after viewing the VIT. STUDY DESIGN: Prospective study. SETTING: Multi-institutional. METHODS: Sixteen fellowship-trained pediatric otolaryngologists who treat velopharyngeal insufficiency (VPI) rated 50 video segments using the GKS before and after watching the VIT. Raters assessed gap size percentage and lateral pharyngeal wall (LPW), soft palate (SP), and posterior pharyngeal wall (PPW) movement. Intraclass correlation coefficient was estimated for these continuous measures. Raters also indicated the presence of a palatal notch, Passavant's ridge, and aberrant pulsations (categorical variables). Fleiss κ coefficient was used for categorical variables. Wilcoxon signed-rank test was performed on the difference between the pre/post individual video ratings. RESULTS: Reliability improved for all continuous variables after watching the instructional video. The improvement was significant for PPW (0.22-0.30, P < .001), SP (left: 0.63-0.68, P < .001 and right: 0.64-0.68, P = .001), and LPW (left: 0.49-0.54, P = .01 and right: 0.49-0.54, P = .09) but not significant for gap size (0.65-0.69, P = .36). Among categorical variables, agreement on Passavant's ridge significantly improved (0.30-0.36, P = .03). CONCLUSION: Exposure to a video instruction tool improves interrater agreement of endoscopic assessment of VP function. Significant improvement was observed in our primary end points, specifically posterior pharyngeal wall movement, soft palate movement, and lateral pharyngeal wall movement. There was less impact of the VIT on the interrater agreement of the categorical variables, palatal notch, Passavant's ridge, and aberrant pulsations.

Hearing screening practices among a national sample of primary care pediatricians.

The objective of this study was to describe variations in hearing screening using a survey mailed to a national sample of primary care pediatricians prior to the 2003 American Academy of Pediatrics (AAP) hearing screening guidelines. Of the 390 primary care respondents, only 303 (78%) performed audiometry, routinely beginning at age 3 (32%), 4 (44%), or 5 (17%); 81% defined abnormal audiometry primarily as failure to hear at a specified decibel level: 15 dB hearing level (HL) (<1%), 16 to 20 dB HL (10%), 21 to 25 dB HL (23%), 26 to 30 dB HL (44%), 31 to 40 dB HL (16%), and more than 40 dB HL (6%). This study serves as a baseline for comparison with postguideline practices.

Hearing screening at well-child visits.

OBJECTIVES: To determine hearing screening failure rates in primary care settings and to examine the referral practices in response to an abnormal screening test. METHODS: We enrolled a convenience sample of children between 3 and 19 years of age who were undergoing hearing screening during a well-child visit. A failure was defined as missing any frequency (1000, 2000, or 4000 Hz) in either ear at 20-dB hearing level. The pediatrician made the decision of whether to refer the patient for further evaluation. RESULTS: Three academic and 5 private practices enrolled 1061 children. Sixty-seven children (7%) were unable to complete the screening. Of the 948 children who completed the screen, a total of 852 children (90%) passed the screening and 96 children (10%) failed. After multivariable logistic regression analysis, the only statistically significant factor predictive of a failed screen was developmental delay (P = .02). Of the 96 children who failed the hearing screening, 57 (59%) had no further evaluation, 12 (13%) were rechecked, and 27 (28%) were referred. Similar percentages were seen with children who could not be screened. CONCLUSIONS: Although 10% of the children failed hearing screening, pediatricians neither rechecked nor referred more than half of these children. Screening that does not result in action for those failing the screening wastes resources and fails to properly identify hearing impairment in children.

Microdebrider versus CO2 laser removal of recurrent respiratory papillomas: a prospective analysis.

OBJECTIVE: To compare postoperative patient discomfort, voice quality, and procedure time and cost for removal of recurrent respiratory papillomas using the microdebrider versus the CO2 laser. STUDY DESIGN: A randomized prospective study comparing children undergoing excision of recurrent respiratory papillomas by CO2 laser versus excision by microdebrider. METHODS: For the 6-month study, patients for whom removal of recurrent respiratory papillomas was indicated were randomly assigned by birth year to microdebrider or CO2 laser therapy. Disease severity was scored as the sum of ratings of 1+ (minimal), 2+ (moderate), or 3+ (severe) for involvement of 27 areas of the aerodigestive tract by direct microlaryngoscopy immediately before treatment. Parents scored patient discomfort and improvement in voice quality 24 hours after surgery, using a 5-point (0 = no pain; 4 = worst pain) and a 10-point (1 = minimal change; 10 = significant improvement) scale, respectively. RESULTS: Nineteen patients ranging in age from 2.5 to 20 years underwent 32 procedures in all. Groups did not differ significantly in age, sex, or severity of disease. For disease of equivalent severity, microdebrider treatment was associated with equivalent 24-hour-postoperative pain scores, greater improvement in voice quality, shorter procedure times, and lower overall procedure cost. CONCLUSIONS: Immediate postoperative results indicate that the microdebrider may be as safe as and, at some institutions, might be more cost-effective than the CO2 laser for removal of recurrent respiratory papillomas.

Success and complications of four-duct ligation for sialorrhea.

OBJECTIVE: Sialorrhea can have a significant negative effect on quality of life, impeding social interactions and severely limiting employment opportunities. Many surgical options to control sialorrhea have been reported. One of the newest procedures is combined ligation of the submandibular and parotid ducts, reported only once in the literature in one series of five patients to date. We have compared results in our first 21 patients undergoing this procedure with results reported in the literature for other procedures to treat sialorrhea. MATERIALS AND METHODS: We retrospectively reviewed medical records of all 21 children we treated with four-duct ligation, a relatively simple intraoral procedure to control sialorrhea, between August 1999 and September 2000 and contacted primary caregivers by telephone to answer a questionnaire regarding objective and subjective results of surgery. Surgery was considered successful when caregivers rated patients as 'much better' or 'better' after surgery. RESULTS: Follow-up was completed in all 21 of the patients 1-14 months after surgery. The success rate of four-duct ligation ('much better' or 'better' after surgery) was 81%, and no patient's sialorrhea problem was worse after surgery. Major complications occurred in two (10%) of the patients (one ranula and one case of sialoadenitis), which were both successfully treated surgically. Minor complications occurred in four (19%) of the patients, tongue swelling that prolonged hospitalization, a ranula that resolved, and prolonged submandibular gland swelling that resolved (two cases). More than half of patients were discharged the day of or the day after surgery. CONCLUSIONS: Four-duct ligation should be considered when surgery is indicated to treat sialorrhea.

Multiple intraparenchymal parotid calculi: a case report and review of the literature.

We describe an unusual case of bilateral intraparenchymal parotid stones with unilateral parotitis in a 17-year-old boy. The patient went on to develop multiple parotid abscesses, which we treated with a superficial parotidectomy. To our knowledge, this is only the second report of intraparenchymal parotid stones in a pediatric patient.

Operative management of choanal atresia: a 15-year experience.

OBJECTIVE: To analyze factors affecting 15-year surgical outcomes of choanal atresia repair. DESIGN: Case series. SETTING: Tertiary care pediatric hospital. PATIENTS: Between April 17, 1996, and March 23, 2010, a total of 42 patients aged 3 days to 15 years underwent endoscopic or transpalatal choanal atresia repair by our pediatric otolaryngology faculty. MAIN OUTCOME MEASURES: Reoperation and restenosis rates, with consideration of effects of mitomycin C therapy, stenting, and postoperative dilation. RESULTS: Three of 42 patients were excluded because of inadequate follow-up data; the follow-up time for the remaining 39 patients averaged 6.3 years (range, 1-14.9 years). Excluding 6 patients whose initial repair was performed by other physicians, 31 of 33 patients in whom we performed initial repair had a total of 43 endoscopic surgical procedures (19 patients had unilateral procedures, and 12 patients had bilateral procedures), and the other 2 underwent bilateral transpalatal repair. Of the total 43 sides we operated on endoscopically, 9 sides (21%) required revision surgery, including excision of scar tissue or additional drilling of persistent bony stenosis. No significant difference was observed in the rate of restenosis among cases treated endoscopically with mitomycin C (22 of 43 operative sides, P = .13), with stenting (36 of 43 operative sides, P = .99), or with subsequent dilation (P = .45). When we used stents, they were usually (in 28 of 36 patients) left in place for 15 days or longer. CONCLUSION: Our revision rate after initial endoscopic repair of choanal atresia was low and was unaffected by adjuvant mitomycin C therapy or stenting.

Fixation methods in pediatric cochlear implants: retrospective review of an evolution of 3 techniques.

OBJECTIVE: To review 3 techniques of cochlear implant (CI) fixation used by a single surgeon for the fixation of 320 consecutive CIs in a pediatric population and associated complications. STUDY DESIGN: Case series with chart review. SETTING: Tertiary referral children's hospital. SUBJECTS AND METHODS: Patients receiving CIs between July 1995 and July 2009 were reviewed. Clinical information obtained included age at implant, implant type, duration of follow-up, method of implant fixation (intraosseous suture ligature, prolene mesh with titanium screws, and a small periosteal pocket with periosteal sutures), and postoperative complications of fixation (migration or extrusion). RESULTS: Three hundred twenty consecutive CIs were reviewed: 64 of which were bilateral (42 staged, 22 concurrent). The median age at implantation was 3.6 years (range, 8 months to 20 years). Manufacturers included Cochlear (223) and Advanced Bionics Corporation (97). Median follow-up was 26 months (range, 1 month to 12.7 years). The intraosseous suture ligation method of fixation was used for 182 CIs. Ninety-eight CIs were fixed using a small piece of polypropylene mesh and titanium screws. Forty implants were secured by using a tight periosteal pocket and placing the suture through the periosteum and soft tissue to collar the receiver in a modified well. No complications of device migration or extrusion were noted, nor were there any intracranial complications. Device failure occurred in 13 (4%) patients requiring explantation and reimplantation, but these were unrelated to surgical technique or fixation. CONCLUSIONS: This study illustrates that with an evolution toward less invasive and less complex methods of fixation, there has not been an associated increase in fixation-related complications.

MRSA and non-MRSA otorrhea in children: a comparative study of clinical course.

OBJECTIVE: To test the perception that post-tympanostomy tube otorrhea caused by methicillin-resistant Staphylococcus aureus (MRSA) is a more virulent disease than otorrhea caused by other pathogens by analyzing the clinical differences and disease courses in children diagnosed with otorrhea caused by MRSA bacteria vs non-MRSA bacteria. DESIGN: Retrospective review. SETTING: Tertiary children's hospital. PATIENTS: We retrospectively examined the medical records of children who presented to a tertiary children's hospital from January 1, 2003, to December 31, 2008, with otorrhea that occurred after tympanostomy tube insertion. MAIN OUTCOME MEASURES: Otorrhea culture records were used to group the 1079 patients into those whose otitis media was due to MRSA (n = 170) and those with non-MRSA otitis media (n = 909). From the non-MRSA group, we randomly selected an age-matched group of 170 and examined the differences between the MRSA and age-matched non-MRSA groups in organisms isolated by culture, demographic factors (including type of medical insurance), medical history, treatments, surgical procedures performed, audiometric data, and other admissions for infection-related illnesses. RESULTS: The overall incidence of MRSA in this series was about 16% (170 of 1079 patients). Of the 170 eligible children in each age-matched group, 135 with MRSA otorrhea and 141 with non-MRSA otorrhea had data in every category selected for statistical analysis. The groups did not differ significantly in type of insurance; history of tympanostomy tube placement, cholesteatoma, or prematurity; number or type (minor/major) of surgical procedures performed; or risk of subsequent infection-related diagnoses. More patients in the MRSA group received intravenous antibiotic therapy (11% vs 3.6%; P < .001). CONCLUSION: In this study, a diagnosis of otorrhea due to MRSA did not carry an increased risk for surgical procedures or infection-associated sequelae compared with a diagnosis of non-MRSA otorrhea.

The management of myringotomy tubes in pediatric cochlear implant recipients.

OBJECTIVE: To investigate the impact of myringotomy tubes (MTs) on outcomes for pediatric cochlear implant (CI) recipients. DESIGN: Retrospective case-control chart review. SETTING: Tertiary care pediatric hospital. PATIENTS: Sixty-two patients received an MT before CI (mean [SD] age at initial CI, 3.20 [2.45] years). Seventy-eight ears received CIs and MTs. INTERVENTION: The MTs were removed and allowed to extrude before CI (59% [n = 46]) or kept in place until CI (41% [n = 32]). MAIN OUTCOME MEASURES: Otorrhea, persistent tympanic membrane (TM) perforation, and need for additional procedures were recorded. Statistical analysis was performed with the Fisher exact test. RESULTS: Forty ears (51%) required more than 1 set of MTs. Ten ears (22%) in which the MTs were removed before CI required a separate MT after CI compared with 6 ears (19%) in which the MTs remained in place until CI (P = .78). The MTs that were present during CI were either removed with myringoplasty (31% [n = 10]) or retained after surgery (69% [n = 22]). All TMs in which the tubes were removed before or during CI healed. There were 3 persistent TM perforations that required surgical treatment. There were no cases of meningitis and no removals of CIs because of infection. CONCLUSIONS: Myringotomy tubes do not appear to adversely affect the final outcomes of pediatric CI recipients and can be managed similarly to MTs in other otitis media-prone children. They may be left in place in children who continue to experience recurrent acute otitis media or removed in children who no longer need them.

The multidisciplinary evaluation and management of cleft lip and palate.

Cleft lip with or without a cleft palate (CLP) and cleft palate alone (CPA) are common birth defects, with a combined birth prevalence of about 1 to 2/1,000. Affected children have a number of medical issues and potential complications, and therefore require a wide variety of healthcare specialists beyond plastic surgeons and dental specialists. For this reason, the best environment in which to deliver this care is a multidisciplinary cleft clinic (MCC) that features a team of healthcare providers, including audiology, pediatric otolaryngology, speech pathology, occupational/feeding therapy, and genetics. In this setting, the many medical issues that these children face are comprehensively addressed in the most convenient manner, as all the specialists can be seen in a single busy day. Furthermore, the referring primary care provider (PCP) will receive a concise letter that documents the team evaluation, including future management plans and recommendations for therapy. Unfortunately, few papers are available in the literature that review the workings of these clinics. In this paper we will provide such an overview, discussing the management issues for children with CLP/CPA, and how these are addressed by members of the MCC.

The use of genetic testing in the evaluation of hearing impairment in a child.

PURPOSE OF REVIEW: To review the role of genetic testing in the evaluation of hearing impairment in children. RECENT FINDINGS: The introduction of genetic testing has greatly enhanced the evaluation of deafness and hearing impairment in children. It can save time and money as well as providing patients, their families, and their physicians with important information; however, this testing is different from the medical testing that pediatricians typically order. SUMMARY: For patients and families to realize the benefits of genetic testing it must be done early in the evaluation process and must be accompanied by appropriate pretest and posttest counseling.
