Abstract
Background The authors sought to compare simultaneous and sequential tympanoplasty and adenoidectomy surgery in pediatric patients. Methods This retrospective single-center study included 65 children (36 males, 29 females; mean age 9.16 ± 3.82 years; range 3–17 years) requiring both tympanoplasty and adenoidectomy. Simultaneous surgeries were performed on the same day, during single general anesthesia, whereas sequential surgeries were separated at least 12 weeks. The groups were compared with regard to restoration of hearing, tympanic membrane status, and utilization of medical resources. All study participants had a 12-months follow-up period after surgery. Results No statistically significant differences were observed between the groups regarding pre- and post-operative ABG values and average hearing gains. However, the post-operative ABG was significantly lower than the pre-operative ABG in both groups (p<0.001). There were no significant differences between simultaneous and sequential groups with respect to complete healing rates and complications (all p>0.355). Simultaneous tympanoplasty and adenoidectomy surgery management is associated with a significantly decreased cumulative hospital stay, cumulative operating room time, and cumulative pure surgical time (all p≤0.016). Conclusions The results of first comparative study of simultaneous versus sequential tympanoplasty and adenoidectomy surgery managements demonstrate no advantages for the sequential approach. The same-day surgery can show the clinical outcomes comparable to those in the sequential group. The simultaneous surgery approach appears to be associated with reduced medical resources consumption. Therefore, simultaneous surgery management is an effective and safe option for children with chronic otitis media and adenoid hypertrophy.

Abstract
OBJECTIVES Eustachian tube dysfunction is a common condition that may lead to otitis media with effusion, hearing loss and developmental delays in children. We sought to determine the efficacy and safety of balloon dilation of the eustachian tube (BDET) in the pediatric population. DATA SOURCES Original studies of BDET in a pediatric population were identified in PubMed, Embase, Web of Science, Cochrane, Clinicaltrials.gov and CINAHL. METHODS Outcomes of efficacy included audiometric findings and adverse events were summarized for each study. RESULTS Seven articles were included involving 408 children with a mean age of 9.9 years old (95%CI 8.8, 11.1) and a mean follow up of 19.2 months (95%CI 15, 23). Type B tympanograms decreased after BDET from 64.2% (95%CI 53.3, 73.8) to 16.1% (95%CI 8.5, 28.4). Air-bone gap (ABG) decreased after BDET from a mean of 25.3 dB (95%CI 18.9, 31.6) to 10.2 dB (95%CI 8.9, 11.5). The pooled estimate of adverse events after BDET was 5.1% (95%CI 3.2, 8.1), the majority being self-limited epistaxis with no major adverse events reported. Three studies compared BDET to ventilation tube insertion; analysis of post-operative ABG showed a greater decrease in the BDET group (mean difference -6.4 dB; 95%CI -9.8, -3.1; p = 0.002). CONCLUSION Although there are no prospective randomized control trials, BDET ± tympanostomy tube placement may produce outcomes that are comparable to tympanostomy tube placement in the treatment of otitis media with effusion in the pediatric population. Most children undergoing the procedure are those with recalcitrant disease. The procedure is safe with the most common complication being epistaxis.

Abstract
Inflammation of the middle ear, known clinically as chronic otitis media, presents in different forms, such as chronic otitis media with effusion (COME; glue ear) and chronic suppurative otitis media (CSOM). These are highly prevalent diseases, especially in childhood, and lead to significant morbidity worldwide. However, much remains unclear about this disease, including its aetiology, initiation and perpetuation, and the relative roles of mucosal and leukocyte biology, pathogens, and Eustachian tube function. Chronic otitis media is commonly modelled in mice but most existing models only partially mimic human disease and many are syndromic. Nevertheless, these models have provided insights into potential disease mechanisms, and have implicated altered immune signalling, mucociliary function and Eustachian tube function as potential predisposing mechanisms. Clinical studies of chronic otitis media have yet to implicate a particular molecular pathway or mechanism, and current human genetic studies are underpowered. We also do not fully understand how existing interventions, such as tympanic membrane repair, work, nor how chronic otitis media spontaneously resolves. This Clinical Puzzle article describes our current knowledge of chronic otitis media and the existing research models for this condition. It also identifies unanswered questions about its pathogenesis and treatment, with the goal of advancing our understanding of this disease to aid the development of novel therapeutic interventions. Summary: Chronic middle ear inflammation is a common disease. Animal models, and in particular mouse models, have been used to elucidate some potential mechanisms, including dysfunction in immune signalling, mucociliary function or Eustachian tube function.

Abstract
Otitis media is a common childhood infection of the middle ear and a major cause of morbidity. This multifactorial disease manifests as a spectrum of clinical syndromes from uncomplicated acute otitis media to more complex recurrent and chronic cases (frequently polymicrobial), with the major pathogens involved being Streptococcus pneumoniae and non-typeable Haemophilus influenzae. Pneumococcal conjugate vaccines (PCVs) target only a few serotypes that cause otitis media; however, results from studies suggest that existing PCVs can prevent early episodes of disease associated with vaccine serotypes, resulting in a reduction of subsequent complex cases caused by non-vaccine serotypes and other otopathogens, which contribute considerably to the disease burden. In this Review, we discuss the role of pneumococcus in the disease continuum and assess clinical evidence showing the effect of prevention of early episodes on the complex interplay between bacterial species implicated in otitis media.

Clinical Practice Guideline: Otitis Media with Effusion (Update). Otolaryngol Head Neck Surg 2016; 154:S1-S41.

Abstract
OBJECTIVE This update of a 2004 guideline codeveloped by the American Academy of Otolaryngology-Head and Neck Surgery Foundation, the American Academy of Pediatrics, and the American Academy of Family Physicians, provides evidence-based recommendations to manage otitis media with effusion (OME), defined as the presence of fluid in the middle ear without signs or symptoms of acute ear infection. Changes from the prior guideline include consumer advocates added to the update group, evidence from 4 new clinical practice guidelines, 20 new systematic reviews, and 49 randomized control trials, enhanced emphasis on patient education and shared decision making, a new algorithm to clarify action statement relationships, and new and expanded recommendations for the diagnosis and management of OME. PURPOSE The purpose of this multidisciplinary guideline is to identify quality improvement opportunities in managing OME and to create explicit and actionable recommendations to implement these opportunities in clinical practice. Specifically, the goals are to improve diagnostic accuracy, identify children who are most susceptible to developmental sequelae from OME, and educate clinicians and patients regarding the favorable natural history of most OME and the clinical benefits for medical therapy (eg, steroids, antihistamines, decongestants). Additional goals relate to OME surveillance, hearing and language evaluation, and management of OME detected by newborn screening. The target patient for the guideline is a child aged 2 months through 12 years with OME, with or without developmental disabilities or underlying conditions that predispose to OME and its sequelae. The guideline is intended for all clinicians who are likely to diagnose and manage children with OME, and it applies to any setting in which OME would be identified, monitored, or managed. This guideline, however, does not apply to patients <2 months or >12 years old. ACTION STATEMENTS The update group made strong recommendations that clinicians (1) should document the presence of middle ear effusion with pneumatic otoscopy when diagnosing OME in a child; (2) should perform pneumatic otoscopy to assess for OME in a child with otalgia, hearing loss, or both; (3) should obtain tympanometry in children with suspected OME for whom the diagnosis is uncertain after performing (or attempting) pneumatic otoscopy; (4) should manage the child with OME who is not at risk with watchful waiting for 3 months from the date of effusion onset (if known) or 3 months from the date of diagnosis (if onset is unknown); (5) should recommend against using intranasal or systemic steroids for treating OME; (6) should recommend against using systemic antibiotics for treating OME; and (7) should recommend against using antihistamines, decongestants, or both for treating OME.The update group made recommendations that clinicians (1) should document in the medical record counseling of parents of infants with OME who fail a newborn screening regarding the importance of follow-up to ensure that hearing is normal when OME resolves and to exclude an underlying sensorineural hearing loss; (2) should determine if a child with OME is at increased risk for speech, language, or learning problems from middle ear effusion because of baseline sensory, physical, cognitive, or behavioral factors; (3) should evaluate at-risk children for OME at the time of diagnosis of an at-risk condition and at 12 to 18 months of age (if diagnosed as being at risk prior to this time); (4) should not routinely screen children for OME who are not at risk and do not have symptoms that may be attributable to OME, such as hearing difficulties, balance (vestibular) problems, poor school performance, behavioral problems, or ear discomfort; (5) should educate children with OME and their families regarding the natural history of OME, need for follow-up, and the possible sequelae; (6) should obtain an age-appropriate hearing test if OME persists for 3 months or longer OR for OME of any duration in an at-risk child; (7) should counsel families of children with bilateral OME and documented hearing loss about the potential impact on speech and language development; (8) should reevaluate, at 3- to 6-month intervals, children with chronic OME until the effusion is no longer present, significant hearing loss is identified, or structural abnormalities of the eardrum or middle ear are suspected; (9) should recommend tympanostomy tubes when surgery is performed for OME in a child <4 years old; adenoidectomy should not be performed unless a distinct indication exists (nasal obstruction, chronic adenoiditis); (10) should recommend tympanostomy tubes, adenoidectomy, or both when surgery is performed for OME in a child ≥4 years old; and (11) should document resolution of OME, improved hearing, or improved quality of life when managing a child with OME.

Abstract
OBJECTIVES Avoiding oral steroids for otitis media with effusion (OME) is endorsed as a performance measure by the National Quality Foundation, but data regarding current gaps and practice patterns are lacking. Our objectives were to evaluate oral steroid use for OME and the related diagnoses of eustachian tube dysfunction (ETD) and tympanic membrane retraction (TMR), to assess variations by visit setting, and to identify opportunities for measurable performance improvement. STUDY DESIGN Cross-sectional analysis of a national database. SETTING Ambulatory visits in the United States. SUBJECTS Children and adults in the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey (2005-2010). METHODS Data were coded for patient demographic information, potential confounders (eg, concurrent conditions managed by oral steroids), and diagnosis of OME, ETD, or TMR (OME/ETD/TMR). The latter 2 diagnoses were included to meet minimum numbers for reliability of weighted estimates, but OME constituted the majority of cases. Multivariate regression was used to determine the variables associated with oral steroid use. RESULTS Among 590,772 observations representing 7,191,711,480 visits for OME/ETD/TMR, 3.2% resulted in a new prescription for oral steroid medication (2.3% for children, 7.0% for adults). Adults were more likely to receive steroids (odds ratio = 3.50, P < .001) than those with other diagnoses, but a similar association was not found for children. Patients seen by an otolaryngologist or in the emergency department were less likely to receive steroids than those seen in other settings. CONCLUSIONS OME/ETD/TMR is infrequently treated with oral steroids, particularly in children. Opportunities for performance improvement are limited.

Abstract
OBJECTIVE The likelihood of a patient attending regular follow up can affect decision making when planning and performing tympanomastoid surgery. This study investigated whether demographic factors were associated with loss to follow up. METHODS A database of patients who had been investigated and treated for chronic otitis media was searched. Patients lost to follow up and a matching sample of patients who were formally discharged were identified. The demographic factors of age, sex and postcode were compared between the two groups. The information collected was also used to provide measures of deprivation. RESULTS Fifty patients in each group were identified. Patients lost to follow up were significantly younger than patients formally discharged (p < 0.02), and were more likely to live in an area of education and training deprivation (p < 0.05). CONCLUSION Younger patient age, and living in an area of education and training deprivation, are associated with a higher incidence of loss to follow up.

Abstract
Objectives The otitis media with effusion (OME) clinical practice guideline endorsed by the American Academy of Otolaryngology—Head and Neck Surgery Foundation, the American Academy of Pediatrics, and the American Academy of Family Physicians recommends against using antihistamines. Avoiding antihistamines was previously endorsed as a performance measure by the National Quality Foundation, but data regarding current practice patterns are lacking. Thus, our objectives were to evaluate (1) antihistamine usage in association with OME, (2) whether practice varies according to visit setting, and (3) if usage patterns are such that a future change would be measurable. Study Design Cross-sectional analysis. Setting Ambulatory visits in the United States. Subjects and Methods National Ambulatory Medical Care Surveys and National Hospital Ambulatory Medical Care Surveys, 2005-2010; univariate, multivariate, and stratified analyses of antihistamine usage were performed. Results A total of 133,968 observations representing 1.49 × 109 pediatric visits met inclusion criteria. Antihistamines were used in 9.5% of OME visits, as opposed to 5.5% of visits without OME (univariate odds ratio, 1.83; 95% confidence interval, 1.02-3.29; P = .042). Multivariate analysis confirmed that OME was associated with a significant increase in nonsedating antihistamine usage (odds ratio, 3.53; 95% confidence interval, 1.62-7.71; P = .002), when adjusted for age, sex, race/ethnicity, allergic conditions and nasal inflammatory diagnoses. Conclusions Oral antihistamines are significantly more likely to be administered when OME is diagnosed. Although antihistamine use for OME is proportionally low, the high prevalence of OME creates an opportunity for quality improvement. Future changes in clinician behavior in response to an updated guideline or related performance metric could be monitored.

Abstract
CONCLUSION The increased expression of Dec-205, Bcl-10, Tim-3, and Trem-1 mRNAs indicates that these pattern recognition receptors are involved in the pathogenesis of cholesteatoma. OBJECTIVE Changes in expression of pattern recognition receptors may be associated with immune responses in patients with cholesteatoma. We therefore assessed the levels of expression of Dec-205, Bcl-10, Tim-3, and Trem-1 mRNAs associated with innate immune responses in patients with cholesteatoma. METHODS Cholesteatoma specimens were collected from 23 patients diagnosed with acquired cholesteatoma from August 2010 to July 2012. The posterior auricular skin of each patient was used as control. The levels of expression of Dec-205, Bcl-10, Tim-3, and Trem-1 mRNA were assessed quantitatively using real-time RT-PCR and correlated with sex, hearing level, the presence of bacteria, and the need for repeat surgery. RESULTS The levels of expression of Dec-205, Bcl-10, Tim-3, and Trem-1 mRNAs were significantly higher in cholesteatoma than in control skin samples (p < 0.05 each). However, mRNA abundance was not associated with patient sex, hearing level, presence of bacteria or history of reoperation (p > 0.05 each).

Abstract
OBJECTIVES Otitis media has been a serious disease and can be that even today. The diagnosis of otitis media is often difficult. Pneumatic otoscopy, otomicroscopy, and tympanometry can improve the diagnostic quality by indication of fluid in the middle ear and thereby improve the quality of treatment. The aim of this ongoing study is to analyze the use of tympanometry in Denmark after reimbursement for doing tympanometry (November 2006) when clinically indicated. Our research questions were: How many clinics were using tympanometry? How frequent was it used? Is the use increasing? Has the number of GPs in the clinic any relation to the use of tympanometry? METHOD We used information in The Danish National Health Service in three Regions to analyze the use of tympanometry in general practice during the years 2007-2009. The coverage of the GPs is 100% in the regions. RESULTS The three regions counted about half of Danish population. In 2009 the material was 902 different clinics with more than 1700 GPs. In 2007 55% of the clinics did tympanometry, in 2009 the figure was 60%. In the clinics doing tympanometry the median value was 28 tympanometries per year (inter-quartile range 13-53) per GP. The variation in the use of tympanometry was surprisingly high, from none or a few per GP per year to a maximum of more than 500 tympanometric examinations per GP a year. This huge variation has to be discussed. DISCUSSION Many answers can be given. Some of the explanation was problems in doing correct tympanometry, and problems understand the clinical implications of curves and the figures.
