Changes in Otitis Media During COVID-19.

OBJECTIVES: During the COVID-19 pandemic, various non-pharmaceutical interventions such as individual hygiene practices like hand washing, social distancing, and mandates for the use of masks in public spaces were implemented to reduce the spread of the disease. Otitis media (OM) is a common infectious disease. How the changed environment due to the COVID-19 pandemic has influenced the prevalence of infectious diseases like OM is not known. This study aimed to investigate how OM prevalence and trends changed during COVID-19 in Korea. METHODS: OM patient data from 2017 to 2021 were extracted from the Health Insurance Review and Assessment Service database. Patients diagnosed with disease code H66 (suppurative and unspecified otitis media) were selected for analysis. Data on OM prevalence, gender, region, medical institution, and number of ventilating-tube prescriptions were analyzed. All age groups were included, and ages were categorized into 5-year ranges. RESULTS: The number of patients diagnosed with the OM disease code decreased continuously from 2017 to 2021 (1 598 205, 1 560 178, 1 520 948, 983 701, and 734 901). The average OM prevalence per 1000 persons decreased by 45.0% from 30.2 in 2017 to 2019 to 16.6 in 2020 to 2021. The change of OM prevalence was greater for the 0 to 5 age group than other age groups. The decrease in average prevalence per 1000 persons was greatest in the 0 to 5 age group (48.6% decrease from 358.2 in 2017-2019 to 184.1 in 2020-2021). The impact of environmental changes on ventilation-tube insertion was smaller than on OM prevalence. The average number of ventilating-tube insertions decreased by 28.1% from 27 311 in 2017 to 2019 to 19 650 in 2020 to 2021. CONCLUSIONS: OM prevalence decreased by 45.0%, and the number of ventilating-tube insertions decreased by 28.1% in Korea during COVID-19.

Racial Disparity in Tympanostomy Tube Placement in Inpatient Pediatric Admissions.

This study aims to evaluate if race and ethnicity affect rates of tympanostomy tube (TT) placement during inpatient pediatric admissions in children with otologic conditions. A review of the 2016 Kids' Inpatient Database was conducted based on the International Classification of Diseases, 10th revision, Clinical Modification (ICD-10-CM) codes for common otologic conditions. Among 85 827 weighted pediatric inpatient discharges with ICD-10-CM codes for common otologic conditions, 213 underwent TT placement. Odds ratios (ORs) for children of Hispanic ethnicity and Asian or Pacific Islander race undergoing TT placement when compared to other ethnicities and races were 0.60 (P = .011) and 0.21 (P = .040), respectively. Multiple logistic regression showed Hispanic ethnicity was associated with lower rates of TT placement when compared to non-Hispanic white children (OR = 0.62; 95% confidence interval = 0.40-0.96). Future studies should assess why these differences exist and if these differences are associated with racial/ethnic bias or attributed to patient/family preference.

The limits of pandemic precautions: Tympanostomy tube placement in children with cleft palate during COVID-19.

PURPOSE: Coronavirus Disease-2019 (COVID-19) mitigation measures have led to a sustained reduction in tympanostomy tube (TT) placement in the general population. The present aim was to determine if TT placement has also decreased in children at risk for chronic otitis media with effusion (COME), such as those with cleft palate (CP). MATERIALS AND METHODS: A cohort study with medical record review was performed including consecutive children, ages 0-17 years, undergoing primary palatoplasty at a tertiary children's hospital February 2019-January 2020 (pre-COVID) or May 2020-April 2021 (COVID). Revision palatoplasty (n = 29) was excluded. Patient characteristics and middle ear status pre-operatively and at palatoplasty were compared between groups using logistic regression or Wilcoxon rank-sum. RESULTS: The pre-COVID and COVID cohorts included 73 and 87 patients, respectively. Seventy (44%) were female and median age at palatoplasty was 13.5 months for CP ± cleft lip (CP ± L) and 5.5 years for submucous cleft palate (SMCP). In patients with CP ± L, TT were placed or in place and patent at palatoplasty in 28/38 (74%) pre-COVID and 37/50 (74%) during COVID (P = 0.97). In patients with SMCP, these proportions were 5/35 (14%) and 6/37 (16%), respectively (P = 0.82). Examining only patients <2 years of age also revealed no difference in TT placement pre-COVID versus COVID (P = 0.99). Finally, the prevalence and type of effusion during COVID was similar to pre-COVID. CONCLUSIONS: Reduced infectious exposure has not decreased TT placement or effusion at palatoplasty. Future work could focus on non-infectious immunologic factors underlying the maintenance of COME in these children.

Recurrent acute otitis media: a survey of current management in England.

OBJECTIVE: Recurrent acute otitis media is common in children. The preferred treatment measures for recurrent acute otitis media have a mixed evidence base. This study sought to assess baseline practice across ENT departments in England. METHODS: A national telephone survey of healthcare staff was conducted. Every ENT centre in England was contacted. A telephone script was used to ask about antibiotic and grommet use and duration in recurrent acute otitis media cases. RESULTS: Ninety-six centres (74 per cent) provided complete information. Recurrent acute otitis media treatment across England by ENT departments varied. The antibiotic first- and second-line prophylaxis offered varies, with trimethoprim used in 33 centres and 29 centres not offering any antibiotics. The timing or choice about when to use grommets also varies, but 87 centres (91 per cent) offer grommet surgery at one stage. CONCLUSION: The treatments received by children in England for recurrent acute otitis media vary by centre; collaborative research in this area is advised.

Single Visit Evaluation and Tympanostomy Tube Placement for the Treatment of Acute Otitis Media in Children.

OBJECTIVE: To review our experiences with development of a single visit surgery (SVS) program for children with recurrent acute otitis media (AOM) undergoing tympanostomy tube (TT) placement the same day as their otolaryngology surgical consultation. STUDY DESIGN: Retrospective cohort analysis. METHODS: Retrospective series of patients participating in SVS from inception March 1, 2014 to April 30, 2020 were analyzed, with attention to factors associated with increasing interest and participation in SVS and parent experiences/satisfaction. RESULTS: A total of 224 children had TT placed through SVS for AOM management. The average age of patients was 18.1 months (standard deviation 7.8 months), and 130 (58.0%) were male. The median interval between initial contact to schedule SVS, and the SVS date was 15 days (interquartile range 9-23 days). When analyzing year-over-year volumes from inception of SVS, notable increases were seen in 2016 and 2017 after a radio advertisement was played locally. A marked increase in volume was noted after implementation of a Decision Tree Scheduling (DTS) algorithm for children with recurrent AOM. Sixty-six (28.8%) procedures were performed after institution of DTS. A parent survey demonstrated high levels of satisfaction with the SVS experience. Estimations of savings to families in terms of time away from work demonstrated potential for indirect healthcare benefits. CONCLUSIONS: SVS for TT placement was a successful, alternative model of care for management of children with AOM. Marketing strategies regarding SVS, and the inclusion of SVS pathway in DTS platforms increased rates of interest and choice of this option. Parents of children undergoing TT through SVS were satisfied with the overall experience. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:2823-2829, 2021.

Prevalence of Tympanostomy Tube Placement in Relation to Cleft Width and Type.

OBJECTIVES/HYPOTHESIS: The prevalence of tympanostomy tube surgery (TTS) in patients with a cleft deformity was investigated, in relation to cleft width and cleft type. STUDY DESIGN: Retrospective review of medical health records. METHODS: Retrospective review of medical health records. Seventy-eight patients with non-syndromic cleft deformity of the palate and/or alveolus and lip between 2003 and 2017 were investigated. All available medical documents were analyzed. The study group was divided into subgroups: 1) patients with isolated cleft palate (CP) and patients with a cleft palate with cleft lip and alveolus (CLP). 2) According to Veau's classification (I-IV), further subgroups were defined. Cleft width was measured using plaster cast models. RESULTS: TTS was performed in 55% of the patients (n = 43). Considering Veau's classification, TTS was conducted as follows: Veau I 65.2% (n = 15/23), Veau II 55.0% (n = 11/20), Veau III 47.6% (n = 10/21), and Veau IV 50.0% (n = 7/14). Cleft classifications, maxillary arch width, and absolute/relative cleft width had no statistical impact on TTS occurrence. Although no significant correlation could be found, patients in our study group with CP (Veau I and II) underwent TTS more often (60.5%, n = 26/43) than patients with CPL (Veau III and IV; 48.6%, n = 17/35) during a three-year follow-up. CONCLUSION: None of the cleft characteristics examined had a significant impact on the proportion of patients who received TTS. Nevertheless, patients with lower Veau classification and CP received tympanostomy tubes more often. Therefore, otolaryngologists and pediatricians treating children with cleft palate should maintain a high level of suspicion for chronic middle ear effusion, even in patients with small clefts.

Helping Children with Special Needs: Who Receives Tympanostomy Tubes?

OBJECTIVES: Tympanostomy tubes can prevent sequelae of otitis media that adversely affect long term hearing and language development in children. These negative outcomes compound the existing difficulties faced by children who are already diagnosed with developmental disorders. This study aims to characterize this subset of children with developmental disorders undergoing myringotomy and tympanostomy tube insertion. METHODS: A retrospective review using the Kids' Inpatient Database (KID) was conducted, with codes from International Classification of Diseases, Ninth Revision used to query data from the years 2003 to 2012 to determine a study group of children with a diagnosis of a developmental disorder undergoing myringotomy and tympanostomy insertion. This group was compared statistically to patients undergoing these procedures who did not have a diagnosed developmental disorder. RESULTS: In total, 21 945 cases of patients with myringotomy with or without tympanostomy tube insertion were identified, of which 1200 (5.5%) had a diagnosis of a developmental disorder. Children with developmental disorders had a higher mean age (3.3 years vs 2.9 years, P = .002) and higher mean hospital charges ($43 704.77 vs $32 764.22, P = .003). This cohort also had higher proportions of black (17.6% vs 12.3%, P < .001) and Hispanic (23.9% vs 20.6%, P = .014) patients, and had lower rates of private insurance coverage (39.6% vs 49%, P < .001). CONCLUSION: The population of children with developmental disorders undergoing myringotomy or tympanostomy tube placement has a different demographic composition than the general population and faces distinct financial and insurance coverage burdens. Further study should be done to assess if these differences impact long term outcomes.

Long-term Impact of Middle Ear Effusion in Pediatric Tympanostomy Tubes.

OBJECTIVES/HYPOTHESIS: Bilateral myringotomy and tympanostomy tube placement (BMT) is the most common pediatric surgery in the United States. Intraoperative middle ear effusion (MEE) is a risk factor for future BMTs in children with recurrent acute otitis media (RAOM). However, the impact of the type of MEE is unknown. Here, we assess otologic outcomes based on intraoperative MEE type and indication for surgery. STUDY DESIGN: Case series chart review. METHODS: After institutional review board approval, we performed a review of children undergoing BMTs between 2008 and 2009. Included patients had their first BMT, preoperative visit, and an operative report. Patients with cleft palate or Down syndrome were excluded. Indications for surgery included RAOM and chronic otitis media with effusion (COME). Other variables evaluated were future BMT, acquired cholesteatoma, and otorrhea. Logistic regression was used for statistical analysis. RESULTS: Out of 1,045 patients reviewed, 680 were included and underwent their first BMT. There were 619 patients who had RAOM. Serous effusions were present in 22.2%, mucoid in 31.3%, purulent in 12.9%, undocumented or bloody in 2.3% of patients, and 31.2% of patients had dry middle ears. Moreover, 22.7% of patients underwent future BMTs. In RAOM patients, serous effusions decreased odds of perforation (odds ratio [OR]: 0.195, 95% confidence interval [CI]: 0.0438-0.867, P = .032), and purulent effusions increased the odds of in-office otorrhea suctioning (OR: 2.13, 95% CI: 1.20-3.77, P = .010) compared to dry. Mucoid effusions had no significant effect on outcomes in COME or RAOM patients. CONCLUSIONS: Intraoperative MEEs were noted in 68.7% of cases; purulent effusions increase the odds of in-office suctioning in RAOM patients. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E993-E997, 2021.

Risk Factors for Multiple Tympanostomy Tube Placements in Children: Systematic Review and Meta-Analysis.

OBJECTIVES/HYPOTHESIS: To determine the rate and predictors of receiving multiple tympanostomy tube (TT) placements in children. STUDY DESIGN: Systematic review and meta-analysis. METHODS: PubMed, EMBASE, and Cochrane Library databases were searched for studies reporting the risk factors for receiving repeat TT (r-TT) placements in children with chronic otitis media with effusion or recurrent acute otitis media. These articles were systematically reviewed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) recommendations. Data were pooled using a random-effects model. RESULTS: Twenty-one studies involving a total of 290,897 children were included. Among all patients, 24.1% (95% confidence interval (CI), 18.2%-29.9%) underwent ≥2 TT placements and 7.5% (95% CI, 5.7%-9.4%) underwent ≥3 TT placements. Craniofacial disease (odds ratio (OR) 5.13, 95% CI, 1.57-16.74) was the strongest predictor of r-TT. Younger age at initial TT placement and shorter TT retention time were also significantly associated with r-TT. Receipt of primary adenoidectomy with initial TT placement was associated with decreased odds of r-TT (OR, 0.46; 95% CI, 0.39-0.55). Long-term tubes also significantly reduced the odds of r-TT (OR, 0.27; 95% CI, 0.17-0.44). CONCLUSIONS: About 1 in 4 children receiving TT will receive at least one repeat set of TT and about 1 in 14 will receive multiple repeat sets. Concurrent adenoidectomy and long-term tubes reduced the incidence of r-TT. Younger patients and those with earlier extrusion of the initial set are at increased risk for repeat surgery. The identification of these risk factors may improve parental counseling and identify patients who might benefit from closer follow-up. LEVEL OF EVIDENCE: NA Laryngoscope, 131:E2363-E2370, 2021.

Ventilation tube non-function due to blockage in children: the frequency, course and effect on hearing. A prospective cohort study.

OBJECTIVE: To assess the effect on hearing of non-functioning ventilation tubes due to blockage during the first six months post-operatively, using UK national guidelines. METHOD: A prospective, observational study was conducted on 37 children who underwent bilateral ventilation tube insertion. Air and bone conduction thresholds were measured before and following surgery, and at one, three and six months post-operatively. Tube non-function was assessed by tympanometry supported by otoscopy. RESULTS: Post-operatively, an average of 21 per cent of ventilation tubes were non-functioning. Ears with non-functioning tubes had significantly (p = 0.0001) poorer mean air conduction thresholds than functioning tubes, with a magnitude of 6 dB HL. Ears with otorrhoea were most affected (15 per cent). At any one visit, the air-bone gap was closed to 10 dB or less in 76 per cent of ears. Non-functioning tubes reduced this to 56 per cent. Compared with tympanometry, otoscopy underdiagnosed tube non-function due to blockage by 22 per cent. CONCLUSION: Non-functioning of ventilation tubes occurs frequently and can be missed on otoscopy. Although it is associated with poorer air conduction thresholds, the magnitude of this difference is unlikely to warrant further intervention unless there is otorrhoea or recurrence of bilateral hearing impairment.

Utilization of Invasive Procedures for Adult Eustachian Tube Dysfunction.

OBJECTIVE: Eustachian tube dysfunction (ETD) is a common diagnosis among adults presenting for outpatient care. We sought to determine national utilization and the associated cost of invasive procedures for adult ETD. STUDY DESIGN: Cross-sectional study. SETTING: National health care database. SUBJECTS AND METHODS: The Truven Health MarketScan Databases (2010-2014) analytic cohort included health care encounters of patients ≥18 years of age with a diagnosis of ETD or related conditions of otitis media with effusion (OME) or tympanic membrane retraction (TMR). Visits associated with recent diagnoses of acute upper respiratory infection, head and neck cancer, or radiation therapy were excluded. Invasive procedure usage was subdivided into nasal and otologic procedures. RESULTS: ETD, OME, or TMR was diagnosed in 1,298,987 patients, 11.1% of which were chronic. The most common procedure was diagnostic endoscopy (including nasal endoscopy and laryngopharyngoscopy), which was used most frequently in the first 3 months after diagnosis, during which it was performed in 120,971 (9.3%) patients. The most frequent therapeutic nasal procedure was eustachian tube inflation without catheterization, performed in 11,412 patients over 5 years at a total cost of $1,210,939 ($106 per person annually). The most common therapeutic otologic procedure was myringotomy with tympanostomy, performed on 56,137 patients over 5 years at a total cost of $47,713,708 ($810 per person annually). CONCLUSION: Several nasal and otologic procedures are associated with a diagnosis of adult ETD at substantial cost. Development of therapeutic alternatives should be sought to mitigate the need for invasive procedures to treat this condition.

Indirect Impact of Ten-valent Pneumococcal Conjugate Vaccine Program on Reducing Antimicrobial Use and Tympanostomy Tube Placements in Finland.

BACKGROUND: Acute otitis media (AOM) is the most common reason for antimicrobial use, and tympanostomy tube placement (TTP) is the most common reason for surgery requiring general anesthesia in children. Ten-valent pneumococcal conjugate vaccine (PCV10) was introduced in Finland in 2010 for infants. We evaluated the indirect impact of PCV10 on these surrogate otitis outcomes in unvaccinated children. METHODS: Using before-after design, unvaccinated children ineligible for National Vaccination Program (born January 2006 to May 2010) were followed-up during 2012-2016 (target cohort, age 1.5-7 years). The target cohort was compared with an age- and season-matched unvaccinated reference cohort (born January 2000 to May 2004) during 2006-2010. Antimicrobial purchase data were obtained from the Social Insurance Institution of Finland benefits register. We assessed the relative reduction by generalized Cox regression for outpatient purchases of antibiotics recommended for treatment of AOM in the Finnish guidelines. Data on all TTP procedures were obtained from national hospital discharge register and Social Insurance Institution benefits register. RESULTS: The rate of outpatient purchases of antimicrobials recommended for AOM was 51 in the unvaccinated reference cohort and 44/100 person-years in the unvaccinated target cohort; relative rate reduction was 14.7% [95% confidence interval: 14.0-15.3] and absolute rate reduction 7/100 person-years. The rates of TTP in the reference and target cohorts were 1.66/100 and 1.61/100 person-years, respectively. The relative rate reduction was 3.6% (0.7-6.5). CONCLUSIONS: Antimicrobial use and TTP procedures reduced in unvaccinated children after PCV10 introduction in infants. These indirect effects contribute to the savings in health care resource use for otitis and may also help in combating antimicrobial resistance.

Epidemiology of Pediatric Tympanostomy Tube Placement in the United States.

The prevalence of pediatric tympanostomy tube placement (TTP) in the United States has not been reassessed in the past decade. To assess the prevalence of TTP and frequent ear infections (FEI), the National Health Interview Survey for the calendar year 2014 was used. Among 73.1 million children, 6.26 million (8.6%) had TTP. The incidence of FEI was 3.49 million (4.8%). Males (9.6%) were more likely than females (7.5%) to undergo TTP (P = .004). Among children under 2 years of age, 9.1% reported FEI, compared to 3.9% of children aged 3 to 17 years. Among children under 2 years of age, 25% with FEI received TTP vs 1.5% without FEI (P < .001). Among children aged 3 to 17 years, 31.1% with FEI received TTP vs 8.6% without FEI (P < .001). TTP may be increasing nationally, although further assessment of adherence to clinical practice guidelines is needed to investigate this potential trend.

Are Children Scheduled for Ventilation Tubes Insertion Overweight? A Cohort of Israeli Children.

OBJECTIVE: To study the hypothesis that children scheduled for ventilation tube insertion (VTI), a surrogate procedure reflecting otitis media (OM) presence, are overweight or obese. PATIENTS AND METHODS: Charts of Israeli children aged 0 to 9 years undergoing VTI with or without adenoidectomy between 9/1/17 and 3/31/19 in a secondary level hospital were retrospectively identified. We compared their mean body mass index (BMI, kg/m2) to the mean BMI of a control group comprised of children who underwent surgeries unrelated to OM (fracture fixation/reduction, inguinal/umbilical hernia repair, meatotomy, appendectomy). BMI measurements were plotted on gender- and age-matched curves to determine BMI percentile, and were also compared to the national pediatric overweight/obesity data. Normal weight was defined as BMI percentile <85%, overweight was BMI percentile between 85% and 97%, and obesity was BMI percentile >97%. RESULTS: The VTI group included 83 children (mean age: 3.5 ± 1.8 years). The control group included 77 children (mean age: 6.3 ± 1.9 years). No statistically significant difference was found in the mean BMI values between both groups (P = .22). When compared to age- and gender-adjusted 50th BMI percentile of the general pediatric population, the mean BMI of the VTI group was significantly higher: for boys, 16.9 versus 15.2 (P < .01), and for girls, 16.6 versus 15.3 (P = .03), but not in the control group: P = .16 (boys) and P = .11 (girls). CONCLUSION: Children undergoing VTI were overweight when compared to their age- and gender-matched peers. This observation was more noticeable in boys.

Correlation of pre-operative computed tomography, intra-operative findings and surgical outcomes in revision tympanomastoidectomy.

OBJECTIVE: To correlate pre-operative computed tomography findings, intra-operative details and surgical outcomes with cholesteatoma recurrence in revision tympanomastoidectomy. METHODS: This retrospective, non-randomised, single-institution cohort study included 42 patients who underwent pre-operative computed tomography imaging and revision surgery for recurrent chronic otitis media. Twelve disease localisations noted during revision surgery were correlated with pre-operative temporal bone computed tomography scans. A matched pair analysis was performed on patients with similar intra-operative findings, but without pre-operative computed tomography scans. RESULTS: Pre-operative computed tomography identified 25 out of 31 cholesteatoma recurrences. Computed tomography findings correlated with: recurrent cholesteatoma when attic opacification and ossicular chain involvement were present; and revision surgery type. Sinodural angle disease, posterior canal wall erosion and dehiscent dura were identified as predictors of canal wall down tympanomastoidectomy. Patients with pre-operative computed tomography scans had a higher rate of cholesteatoma recurrence, younger age at diagnosis of recurrent disease, more revision surgical procedures and less time between previous and revision surgical procedures (all p < 0.05). CONCLUSION: Pre-operative imaging and intra-operative findings have important clinical implications in revision surgery for chronic otitis media. Performing pre-operative computed tomography increases diagnosis accuracy and reduces the time required to diagnose recurrent disease.

Surgical, speech, and hearing outcomes at five years of age in internationally adopted children and Swedish-born children with cleft lip and/or palate.

Internationally adopted children (IAC) with a cleft lip and/or palate (CL/P) tend to arrive with un-operated palates at an age at which their Swedish-born peers have completed their primary palate surgery. Our aim of the present study was to analyze surgical, speech and hearing outcomes of IAC at age 5 and compare with those of a matched group of Swedish-born children. Fifty children with CL/P born in 1994-2005 participated in the study. Twenty-five IAC were matched according to age, sex and cleft type with 25 Swedish-born children. Audio recordings were perceptually analyzed by two experienced, blinded speech-language pathologists. Hearing and speech statuses were evaluated on the same day for all children. Surgical timing and complications as in fistulas and requirement for secondary velopharyngeal (VP) surgery, speech evaluation results, and present hearing status were analyzed for all children of age 5 years. Results showed that primary palatal surgery was delayed by a mean of 21 months in IAC. IAC had a higher prevalence of velopharyngeal impairment that was statistically significant, a higher fistula rate, and experienced more secondary surgery than Swedish-born peers. Hearing loss due to middle ear disease was slightly more common among IAC, whereas the rate of treatment with tympanostomy tubes was similar between the two groups. In conclusion, IAC with CL/P represent a challenge for CL/P teams because of the heterogeneous nature of the patient group and difficulties associated with delayed treatment, and the results show the importance of close follow-up over time.

Specialists' adherence to guidelines on tympanostomy tube insertion.

INTRODUCTION: Tympanostomy tube insertion is very frequent in Denmark. Using electronic patient-reported outcome (ePRO) data, we investigated Danish ear, nose og throat (ENT) specialists' adherence to the 2015 national clinical guideline (NCG) on first-time tympanostomy tube (TT) insertion in children aged 0-5 years with otitis media (OM). METHODS: Data on children aged 0-5 years with OM undergoing first-time TT insertion were extracted from the Danish ENT Specialists Organisation (DØNHO) database. Pre-operative questionnaires were used to obtain information on symptom duration, and the number of acute OM (AOM) episodes was analysed. The following criteria were established to define NCG adherence: 1) A symptom duration of three months or longer, 2) three or more AOM episodes within six months and 3) four or more AOM episodes within 12 months. These criteria are in accordance with the NCG definition of chronic OM with effusion (COME) and recurrent AOM (RAOM). RESULTS: A total of 1,495 children were included in the study. In total, 91.0% of the parents reported a symptom duration of three months or more and/or RAOM within 6-12 months prior to TT insertion in accordance with the adherence criteria; 4.6% reported a symptom duration of less than three months with few or no episodes of AOM and did not meet the recommended TT insertion criteria. Finally, 4.4% of the parents were undecided with respect to symptom duration, number of AOM episodes or both at 6-12 months prior to TT insertion. CONCLUSIONS: Using solely ePRO data, we found that Danish practicing ENT specialists adhere to the 2015 NCG in regard to OM symptom duration and RAOM. FUNDING: none. TRIAL REGISTRATION: not relevant.

Epidemiology of common otologic surgical procedures in pediatric patients: A population-based birth cohort study.

OBJECTIVE: It is generally recognized the most common pediatric otologic surgical procedure is ventilation tube insertion (VTI). Tympanoplasty and mastoidectomy are more frequently performed on adults. In this study we examined the incidence and age distribution of these procedures by use of a population-based birth cohort design, in order to provide an overall view of the role of these procedures in the pediatric population. MATERIALS AND METHODS: We used the national health insurance research database in Taiwan. We retrieved data on all patients born in the years 2000 and 2001, subsequently underwent VTI, tympanoplasty or mastoidectomy from 2000 to 2013. The incidence and age distribution of these procedures were analyzed. RESULTS: The cumulative incidence of VTI, tympanoplasty, and mastoidectomy was 0.41%, 0.02% and 0.025%, respectively. VTI were more often performed on children 4 or 5 years of age. Tympanoplasties are frequently done on children older than 5, and 30.7% of them had earlier VTI. The time interval from VTI to tympanoplasty was 5.18 ±â€¯2.27 years (mean ±â€¯SD). Mastoidectomies are more often performed on children from 2 to 9 years of age. CONCLUSIONS: VTI was the most frequent otologic surgery for the pediatric population, and was more often performed on children 4-5 years old. Also, tympanoplasty is more frequently performed on children older than 5, and a third of them had prior VTI. Overall, the time interval from VTI to tympanoplasty was 5.18 years. Furthermore, children with cleft palate and congenital metabolic disorder were more prone to otologic surgical procedures.

Tympanostomy tube insertion practice in under-18-year-olds in the South African private healthcare sector insured by Discovery Health.

BACKGROUND: The reported rates of tympanostomy tube insertion (TTI) in children vary significantly internationally. Lack of adherence to evidence-based clinical guidelines may contribute to these differences. OBJECTIVES: To study the rates of TTI in South Africa (SA) in children ≤18 years old in the private healthcare sector, both nationally and regionally, to compare these with international TTI rates, and to determine the use of preoperative audiometry and tympanometry. METHODS: A retrospective analysis was done of data obtained from the Discovery Health database. Rates of TTI were analysed nationally and regionally and in different age groups, as was the use of tympanometry and audiograms. RESULTS: The SA TTI rates were much higher than published international rates except for the 0 - 1-year age group in Canada and Denmark and the 0 - 15-year age group in Denmark. There was a statistically significant regional variation in TTI rates as well as in the use of preoperative audiometry and tympanometry. CONCLUSIONS: SA private sector TTI rates are high by international standards. Significant regional variations may indicate over- or underservicing in certain regions. Further investigation of causes for the high TTI rate and regional variations is recommended. Education of healthcare professionals on recognised indications for TTI may improve patient selection.
