The use of hearing tests to assess otitis media with effusion in children with Down syndrome.

BACKGROUND: Down syndrome is associated with an increased risk for otitis media with effusion (OME), a childhood condition in which fluid accumulates in the middle ear, potentially leading to hearing loss. The American Academy of Pediatrics Down syndrome guidelines and the American Academy of Otolaryngology - Head and Neck Surgery OME guidelines recommend hearing testing to assess the hearing status of children with Down syndrome diagnosed with OME. METHODS: Through an Institutional Review Board approved retrospective chart review at Children's Mercy, this project assessed how clinical factors affect the frequency in which children with Down syndrome receive hearing testing after diagnosis of OME. The study included data from all children with Down syndrome between 1 and 8 years old diagnosed with OME in the Down syndrome, general pediatrics, and otolaryngology clinics between 2018 and 2020. Demographics and clinical factors, including clinic setting, were collected. RESULTS: Of the 124 patients identified, 91.1 % were diagnosed with OME in the otolaryngology clinic and 33.1 % received hearing testing. While most diagnoses occurred in the otolaryngology clinic, a higher proportion of hearing testing at the time of diagnosis occurred in the Down syndrome clinic. This could be explained by the fact that the Down syndrome clinic is a multidisciplinary clinic, where yearly visits include hearing screening. Bivariate analysis using chi-square or Fisher's tests showed that clinic setting had a significant association (p-value <0.001) with hearing testing. However, logistic regression depicted all clinical factors had an insignificant effect on hearing testing at 5 % significance. CONCLUSION: While results indicate hearing testing is largely not performed to assess OME early in otolaryngology clinics, they may be used to assess intervention efficacy post-diagnosis. Results point to the importance of Down syndrome clinics in early diagnosis of hearing loss leading to timely referrals to otolaryngology clinics which diagnose and manage OME in children with Down syndrome.

Smartphone-Based Artificial Intelligence for the Detection and Diagnosis of Pediatric Diseases: A Comprehensive Review.

In recent years, the use of smartphones and other wireless technology in medical care has developed rapidly. However, in some cases, especially for pediatric medical problems, the reliability of information accessed by mobile health technology remains debatable. The main aim of this paper is to evaluate the relevance of smartphone applications in the detection and diagnosis of pediatric medical conditions for which the greatest number of applications have been developed. This is the case of smartphone applications developed for the diagnosis of acute otitis media, otitis media with effusion, hearing impairment, obesity, amblyopia, and vision screening. In some cases, the information given by these applications has significantly improved the diagnostic ability of physicians. However, distinguishing between applications that can be effective and those that may lead to mistakes can be very difficult. This highlights the importance of a careful application selection before including smartphone-based artificial intelligence in everyday clinical practice.

Clinical significance of T helper-1/T helper-2 cytokines in peripheral blood of children with otitis media with effusion and allergic rhinitis.

OBJECTIVE: Otitis media with effusion (OME) is a prevalent and costly disease, especially in children. This article analyzed the expression patterns and clinical significance of T helper-1 (Th1)/Th2 cytokines in the peripheral blood of children with OME and allergic rhinitis (AR). METHODS: Subjects were assigned to the OME + AR group and the Control group (children with OME), with their clinical baseline data documented. The correlations between Th1/Th2 cytokines and between the total nasal symptom score (TNSS) and Th1/Th2 cytokines were analyzed. The risk factors and the predictive value of Th1/Th2 cytokines for OME + AR were analyzed using logistics multivariate regression analysis and receiver operating characteristic curve. RESULTS: Significant differences were observed in tympanic pressure/speech frequency/air conduction valve/TNSS score/immunoglobulin E (IgE) level between both groups. The OME + AR children exhibited evidently elevated interleukin-2 (IL-2)/tumor necrosis factor-α (TNF-α)/IL-4/IL-10/IL-6 levels and no significant difference in interferon-γ (IFN-γ) level. Th1/Th2 cytokines were remarkably positively-correlated with the TNSS score. IL-2/TNF-α/IL-4/IL-6 were risk factors for OME with AR. The area under the curves (AUCs) of IL-6/IL-2/IL-4/TNF-α levels in predicting the occurrence of OME + AR were 0.805/0.806/0.775/0.781, with sensitivities of 75.76 %/89.39 %/72.21 %/72.73 % and specificities of 74.29 %/61.34 %/72.86 %/70.00 %, and the cut-off values were 239.600/20.300/29.880/34.800 (pg/mL). The AUC of their combination in predicting OME + AR was 0.955 (93.94 % sensitivity, 85.71 % specificity). CONCLUSION: Th1/Th2 cytokine levels were imbalanced and obviously positively-correlated with the TNSS score in OME + AR children. IL-2, TNF-α, IL-4, and IL-6 levels had auxiliary predictive value in the occurrence of OME + AR.

Long-term follow-up of otitis media with effusion in neonatal hearing screening.

OBJECTIVES: Increased neonatal referral rate of conductive hearing loss (CHL) related to otitis media with effusion (OME) following universal neonatal hearing screening (UNHS) may cause an unnecessary clinical, emotional, and financial burden. This study analyzes the long-term, audiological, and medical characteristics of CHL associated with OME in neonates in order to establish a standardized protocol following technology-driven improvements in detection and referral rates in UNHS. METHODS: A retrospective study of all neonates with OME-related CHL referred to the University Hospital of Leuven (Belgium) after failing UNHS with the MAICO devices between January 1, 2013 and December 31, 2021 was performed. Follow-up consultations, auditory tests, referral side, birth month, hearing loss degree, underlying pathologies and risk factors, time to normalization, and need for ventilation tubes were assessed. RESULTS: The incidence of CHL related to OME was stable between 2013 and 2021. Of all referred infants with OME, 52.3 % demonstrated spontaneous recovery. The average time to hearing normalization was significantly longer in children with underlying congenital pathologies compared to those without. Moreover, 74.4 % of these children received ventilation tubes compared to 32.0 % of children without underlying pathologies. No correlation was found between the incidence of OME-related CHL with either a hearing loss degree, admission to neonatal intensive care, or history of a nasogastric feeding tube. CONCLUSIONS: In children who failed UNHS due to OME, hearing recovers spontaneously without surgical intervention in 2/3 of the infants without underlying conditions within one year. In children with underlying congenital disorders, the time to hearing recovery is longer and the risk for surgical intervention is higher, underlining the need for implementing a UNHS standardized protocol.

A Case of Olfactory Neuroblastoma Developing Bilateral Retropharyngeal Lymph Node Metastasis 14-years After Skull Base Surgery.

Olfactory neuroblastoma (ONB) is an uncommon malignant tumor and is usually treated by a multidisciplinary approach includes surgery, radiotherapy, and chemotherapy. A 62 years-old male had a tumor in the nasal cavity and diagnosed as ONB with Kadish A stage. Anterior skull base surgery was performed as radical treatment. Since the surgical margin was negative, no postoperative radiotherapy was administered. 14 years after the surgery, bilateral otitis media with effusion (OME) was occurred, we found the recurrence tumor at bilateral retropharyngeal lymph node (RPLN) which surrounded the internal carotid arteries. Since these were unresectable, we planned chemoradiotherapy which was 70Gy of intensity modulated radiotherapy combined with two courses of carboplatin and etoposide. The tumor volume was reduced and bilateral OME were improved. He has been alive for 3 years after salvage treatment. Although ONB has a relatively good prognosis, it is known to often cause cervical lymph node metastasis. Grades III and IV of Hyams classification are considered high risk. This case, initial tumor was limited in the nasal cavity and its clinical classification was early stage, but Hyams classification was grade III. In reference to this case, considering that RPLN metastasis are difficult to radically resect at the salvage surgery, including this area in postoperative radiotherapy was considered an option.

'It is difficult for us to assess the severity!' A qualitative analysis of parents' expectations to postoperative care after ventilation tube surgery.

OBJECTIVE: Surgery with ventilation tubes (VT) in children suffering from otitis media with effusion is quite common. However, the knowledge surrounding parents' expectations to the treatment and postoperative care is sparse. The aim of this study was to describe the parents' expectations to VT surgery and postoperative care shortly after surgery. METHODS: A qualitative study was conducted based on semi-structured individual interviews with parents recruited from a study where postoperative care was randomized to either an otolaryngologist or the patient's general practitioner (GP). The interviews were conducted within the first weeks after surgery and analyzed by reflexive thematic analysis. RESULTS: In total, 13 parents aged 29-42 years participated in the study. We identified three main themes elucidating parents' expectations to VT surgery and postoperative care: 1) Preconceptions about VT surgery and hearing - most parents expected surgery to restore the child's normal hearing, and some were uncertain about their knowledge of normal hearing and VT treatment; 2) A safety net to ensure hearing and function - it was reassuring if the child received structured postoperative care that secured and notified appointments and had quick access to a specialist if needed; 3) High-quality care - most parents expected the otolaryngologist to provide the highest level of quality of care due to their specialist competence, special equipment and sufficient understanding of the problem to communicate well with parents. Postoperative care by the GP was perceived as incomplete among most parents due to a lack of both specialist competence and access to audiometry. CONCLUSION: Parents expect postoperative care to safeguard their child as long as needed after VT surgery, and they expect access to high-quality care. Low health literacy among some parents challenges the current method of postoperative care and requires that more emphasis be set on both informing and educating parents regarding hearing and VT treatment.

Otitis media with effusion in preschool children with adenoid hypertrophy: Risk factors and nursing care.

AIM: To evaluate the influencing factors of otitis media with effusion (OME) in children with adenoid hypertrophy and to provide evidence for clinical treatment and care of children with adenoid hypertrophy. DESIGN: A retrospective study. METHODS: Preschool children with adenoid hypertrophy treated in our hospital from 1 January 2021 to 30 July 2022 were included. We analysed the characteristics of OME and non-OME children with adenoid hypertrophy. Pearson correlation analysis and logistic regression analysis were performed to evaluate the risk factors for OME in children with adenoid hypertrophy. CONCLUSION: A total of 166 children with adenoid hypertrophy were included; the incidence of OME in children with adenoid hypertrophy was 34.94%. The incidence of OME decreased significantly with the increase in age (p = 0.014). Logistic regression analysis showed that age < 3 years (OR = 3.149, 95%CI: 2.812-3.807) and duration of adenoid hypertrophy ≥12 months (OR = 2.326, 95%CI: 2.066-2.612) were the risk factors of OME in children with adenoid hypertrophy (all p < 0.05). PATIENT CONTRIBUTION: The incidence of adenoid hypertrophy with OME is high in preschool children, and it is related to the age and duration of adenoid hypertrophy.

Effect of COVID-19 on the characteristics and outcome of patients who have otitis media with effusion: a case-control study.

BACKGROUND: Few studies have examined the otologic symptoms of Coronavirus disease 2019 (COVID-19). The objective of this study was to identify the effect of COVID-19 on the characteristics and outcomes of patients who have otitis media with effusion (OME). METHODS: This case-control study compared the characteristics and outcomes of OME patients who did or did not have COVID-19. A total of 65 patients with previous COVID-19 and 40 patients who did not have COVID-19 (controls) were enrolled from October 1, 2022 to January 31, 2023 at a single institution in China. Demographics, medical histories, morbidities, hearing test results, treatments, and outcomes of the two groups were compared. RESULTS: The COVID-19 group had significantly better outcomes from OME than the control group, with higher rates of complete resolution (64.6% vs. 30%) and improvement (30.8% vs. 17.5%), and a lower rate of persistent OME (4.6% vs. 52.5%). Previous COVID-19 was independently associated with a more favorable OME outcome in three multivariate logistic regression models. The COVID-19 group also had a greater improvement in hearing threshold based on air-bone gap measurements. CONCLUSION: The outcomes of OME patients who had previous COVID-19 were generally good, in that most patients responded well to treatment and achieved complete resolution or improvement within one month.

Efficacy of balloon Eustachian tuboplasty plus tympanostomy tube insertion in postirradiation otitis media with effusion.

OBJECTIVE: This study aimed to compare the efficacy of balloon Eustachian tuboplasty (BET) plus tympanostomy tube insertion (TTI) and simple TTI for postirradiation otitis media with effusion (OME) in patients with nasopharyngeal carcinoma. METHOD: This study included 36 patients (51 ears) with OME after the first radiotherapy course for nasopharyngeal carcinoma and categorized them into the BET + TTI and simple TTI groups. Effective rates, pure tone hearing threshold, Eustachian tube function score, and complication incidences were compared. RESULTS: The effective rates of the BET+TTI and TTI groups were 93.75 % and 75 %, respectively, with no statistically significant difference (P = 0.29). The pure tone hearing threshold examination at 9 months postoperatively revealed significantly lower mean air-pure tone and air-bone gap in both the BET + TTI and TTI groups than preoperatively. Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7) scores at every postoperative visit were significantly higher than preoperative scores in the two groups (all P < 0.05); ETDQ-7 score reduction in the BET + TTI group at 3, 9, and 12 months postoperatively was significantly higher than that in the TTI group. Otorrhea and recurrence both occurred in the BET+TTI and TTI groups, but the BET+TTI group demonstrated a lower incidence. CONCLUSION: BET + TTI is an effective treatment method for postirradiation OME.

Otitis Media With Effusion After the COVID-19 Pandemic: Return to the Past and New Lessons.

OBJECTIVE: To assess the prevalence of otitis media with effusion (OME) among children who attended a tertiary level audiologic center 2 and 3 years after the COVID-19 lockdown, and to determine the impact of temporary interruption of day care center attendance on chronic OME. STUDY DESIGN: Retrospective study. SETTING: Tertiary level referral audiologic center. METHODS: We assessed the prevalence of OME among children aged 6 months to 12 years in 3 different periods (May-June 2022, January-February 2023, and May-June 2023) and compared the results with those of the corresponding periods before the COVID-19 lockdown. We also compared the disease resolution rates between a subgroup of children with chronic OME who interrupted day care center attendance for a 2-month period (Subgroup A) and a similar subgroup who continued attending day care centers (Subgroup B). RESULTS: The prevalence of OME was 38.5% (138/358) in May-June 2022, 51.9% (193/372) in January-February 2023, and 40.9% (149/364) in May-June 2023. No significant prevalence differences were observed between the periods May-June 2019, May-June 2022, and May-June 2023 (P = .78), and between the periods January-February 2020 and January-February 2023 (P = .93). At the May-June 2023 assessment, the children belonging to Subgroup A presented a greater rate of disease resolution (85.7%, 18/21) than the children belonging to Subgroup B (32%, 8/25, P < .001). CONCLUSION: This study suggests that the prevalence of OME has returned to prelockdown levels, and that interrupting day care center attendance for a 2-month period could be effective in resolving most cases of chronic OME.

Tympanostomy Tube Insertion Versus Myringotomy or Observation in Managing Otitis Media With Effusion Following Radiotherapy for Nasopharyngeal Carcinoma: An Updated Review.

Head and neck cancers, including nasopharyngeal carcinoma (NPC), are relatively common in Saudi Arabia. Radiotherapy is a standard treatment for NPC, but it can lead to side effects, including post-radiation otitis media with effusion (OME). Managing post-radiotherapy OME remains a topic of debate, with various interventions proposed. This study aims to review the efficacy of different methods to manage post-radiotherapy OME in NPC. This includes tympanostomy tube insertion, frequent myringotomies, and observation. A systematic review was carried out for articles published between 1975 and 2023 following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Excluded from the analysis were articles that involved patients undergoing surgical treatment for nasopharyngeal cancer, studies that focused on patients with other head and neck cancers who developed OME after radiotherapy, research investigating the effectiveness of surgical procedures unrelated to tympanostomy tube insertion, studies written in non-English language, and case reports, reviews, or conference letters. A total of 450 studies were screened, of which six studies were included in the review, yielding 328 patients. The mean age ranged between 46 and 52 years. Follow-up varied from six months to 11 years. The intervention in all studies was tympanostomy tube insertion, and the controls were myringotomy, observation, or tympanic membrane fenestration with cauterization. The use of recurrent myringotomies for the treatment of OME in patients with NP post-radiotherapy is associated with improved chances for the resolution of effusion and decreased risk of complications when compared to tympanostomy tube insertion. Hence, we recommend following a step-wise approach when dealing with this group of patients, offering grommets for patients with persistent effusion or those who cannot tolerate frequent procedures.

Impact of Otitis Media With Effusion in Early Age on Auditory Processing Abilities in Children: A Systematic Review and Meta-Analysis.

Objective: Early-onset otitis media with effusion (OME) can affect the development of the auditory nervous system and thus lead to auditory processing abnormalities. This study aims to review the effect of childhood OME on auditory processing abilities in children. Methods: A systematic review of the literature, restricted to the English language from 1990 to 2022 was conducted using search engines like PubMed, Embase, and Google Scholar. After selecting the articles following predefined inclusion and exclusion criteria, the data were extracted and meta-analysis was performed. Results: A total of 10 articles met the inclusion criteria. Children with a history of OME had poorer performance in most behavioral and electrophysiological tests. Pooled analysis of various tests such as the gap in noise test, frequency pattern test (verbal and nonverbal), and latencies of auditory brainstem response-I, V, I to III, and I to V showed a difference between the 2 groups. Conclusion: Childhood OME can significantly affect auditory processing abilities in children.

Causal Relationship Between Body Mass Index and Risk of Otitis Media with Effusion in Children: A Mendelian Randomization Study.

Background: Body mass index(BMI) in children appears to be associated with Otitis media with effusion(OME) in observational studies, but the causal relationship is not clear. Methods: A two-sample Mendelian randomization (MR) study was used to explore the causal relationship between childhood BMI and OME in people of European ancestry. Genome-wide association studies (GWAS) of childhood BMI were used as exposures (n = 61,111), while GWAS of OME were used as outcomes (n = 429,290). The weighted inverse variance method (IVW) was used as a baseline method to test for causality. In addition, MR-Egger, simple mode analysis, weighted median, and weighted mode were used as complementary methods.MR-PRESSO analysis, MR-Egger intercept analysis, and Cochran's Q statistical analysis were also used to detect possible directional heterogeneity and polymorphism. To assess this association, we used ratios (OR) with 95% confidence intervals (ci). All statistical analyses were performed in R. Results: We selected 22 genome-wide significant single nucleotide polymorphisms (SNPs) from GWAS as instrumental variables (IVW). the IVW approach showed evidence supporting a causal relationship between BMI and OME in children (ß = 0.265, SE = 0.113, P = 0.018). MR-Egger regression showed that targeted polymorphisms were unlikely to bias the results bias (intercept=-0.022; P = 0.488), but there was no causal relationship between BMI and OME (ß = 0.584, SE = 0.465, P = 0.224). Although the results of the IVW and MR Egger analyses were not consistent, the IVW analysis maintained higher precision, and the Cochran Q test, heterogeneity and polymorphism tests showed no heterogeneity, no directionality and no polymorphism. Conclusions: MR studies suggest that genetically predicted body mass index in childhood is associated with an increased risk of OME. Notably, given the limitations of this study, the mechanism of association between body mass index and OME in childhood needs further investigation. These results support the importance of effective management of obesity, which may reduce OME occurrence and decrease OME recurrence.

Otogenic brain complications: a systematic review and meta-analysis.

OBJECTIVE: This study aimed to form astute deductions regarding the presentation, treatment and mortality of otogenic brain complications. METHODS: A systematic literature search of four medical databases (PubMed, Embase, Web of Science and Scopus) was conducted. Studies associated with otogenic brain complications were considered eligible. Fixed- and random-effects model meta-analysis was developed to assess the proportion estimate for each outcome individually. RESULTS: Twenty-eight studies, with 1650 patients in total, were included. In 66 per cent of patients there was a known history of chronic otitis media. The most common symptoms were purulent otorrhoea (84 per cent), headache (65 per cent) and otalgia (45 per cent). A brain abscess was observed in 49 per cent of patients, followed by meningitis (34 per cent) and sinus thrombosis (22 per cent). A combination of surgical and conservative therapy was chosen in 84.3 per cent of cases and the mortality rate approached 11.1 per cent. CONCLUSION: Otogenic brain complications are a possibly life-threatening condition. Prompt imaging examination may set the final diagnosis and lead to an effective treatment.

Practical guide for the diagnosis and management of primary ciliary dyskinesia.

OBJECTIVE: Primary ciliary dyskinesia (PCD) is a relatively rare genetic disorder that affects approximately 1 in 20,000 people. Approximately 50 genes are currently known to cause PCD. In light of differences in causative genes and the medical system in Japan compared with other countries, a practical guide was needed for the diagnosis and management of Japanese PCD patients. METHODS: An ad hoc academic committee was organized under the Japanese Rhinologic Society to produce a practical guide, with participation by committee members from several academic societies in Japan. The practical guide including diagnostic criteria for PCD was approved by the Japanese Rhinologic Society, Japanese Society of Otolaryngology-Head and Neck Surgery, Japanese Respiratory Society, and Japanese Society of Pediatric Pulmonology. RESULTS: The diagnostic criteria for PCD consist of six clinical features, six laboratory findings, differential diagnosis, and genetic testing. The diagnosis of PCD is categorized as definite, probable, or possible PCD based on a combination of the four items above. Diagnosis of definite PCD requires exclusion of cystic fibrosis and primary immunodeficiency, at least one of the six clinical features, and a positive result for at least one of the following: (1) Class 1 defect on electron microscopy of cilia, (2) pathogenic or likely pathogenic variants in a PCD-related gene, or (3) impairment of ciliary motility that can be repaired by correcting the causative gene variants in iPS cells established from the patient's peripheral blood cells. CONCLUSION: This practical guide provides clinicians with useful information for the diagnosis and management of PCD in Japan.

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.

Otitis media with effusion in adults during the SARS-CoV-2 epidemic.

OBJECTIVES: The purpose of this study was to investigate the fluctuations in the prevalence of individuals diagnosed with otitis media with effusion (OME) during the SARS-CoV-2 pandemic, while also evaluating the persistence of SARS-CoV-2 in middle ear effusion (MEE) and assessing the effectiveness of tympanocentesis as a treatment modality for OME in this specific period. METHODS: The total number of outpatients and patients diagnosed with OME in our department was recorded for January 2022 and January 2023. Thirty patients (aged 15-86 years) were categorized into two groups: group A (n = 12), who developed OME during their SARS-CoV-2 infection and group B (n = 18), who experienced OME after the resolution of SARS-CoV-2 infection. All patients underwent otoendoscopic tympanocentesis (without a ventilation tube), where MEE and nasopharyngeal secretions were simultaneously collected for SARS-CoV-2 detection by polymerase chain reaction. The time interval from SARS-CoV-2 infection to tympanocentesis, results of SARS-CoV-2 detection, preoperative and postoperative average hearing threshold, and Eustachian Tube Dysfunction Questionnaire (ETDQ-7) scores were documented. RESULTS: The proportion of outpatients with OME in January 2023 was higher than that in January 2022. There were five patients who had positive test results for SARS-CoV-2 on MEE after tympanocentesis. These 5 patients underwent tympanocentesis at a mean of 28 ± 7.28 days following confirmation of SARS-CoV-2 infection. The ETDQ-7 scores of group A exhibited a reduction from 21.85 ± 4.8 to 10.00 ± 4.07 following tympanocentesis, while the ETDQ-7 scores of group B also demonstrated a decrease from 21.22 ± 4.65 to 10.11 ± 3.68 after undergoing tympanocentesis. The tympanocentesis was effective in both groups. CONCLUSIONS: The study confirmed that the proportion of outpatients with OME in the Clinics of Otolaryngology during the SARS-CoV-2 epidemic increased significantly. SARS-CoV-2 RNA was detectable in MEE of COVID-19-related OME patients. Tympanocentesis was therapeutic for OME during SARS-CoV-2 infection, which facilitated viral clearance in MEE.

Panel 1: Epidemiology and global health, including child development, sequelae and complications.

OBJECTIVE: To summarise the published research evidence on the epidemiology of otitis media, including the risk factors and sequelae associated with this condition. DATA SOURCES: Medline (PubMed), Embase, and the Cochrane Library covering the period from 2019 to June 1st, 2023. REVIEW METHODS: We conducted a broad search strategy using otitis [Medical Subject Heading] combined with text words to identify relevant articles on the prevalence, incidence, risk factors, complications, and sequelae for acute otitis media, otitis media with effusion, and chronic suppurative otitis media. At least one review author independently screened titles and abstracts of the retrieved records for each condition to determine whether the research study was eligible for inclusion. Any discrepancies were resolved by reviewing the full text followed by discussion with a second review author. Studies with more than 100 participants were prioritised. RESULTS: Over 2,000 papers on otitis media (OM) have been published since 2019. Our review has highlighted around 100 of these publications. While the amount of otitis media research on the Medline database published each year has not increased, there has been an increase in epidemiological studies using routinely collected data and systematic review methodology. Most of the large incidence studies have addressed acute otitis media (AOM) in children. Several studies have described a decrease in incidence of AOM after the introduction of conjugate PCV vaccines. Similarly, a decrease was noted when rates of coronavirus disease of 2019 (COVID-19) were high and there were major public health efforts to reduce the spread of infection. There have been new studies on OM in adults and OM prevalence in a broader range of countries and population subgroups. CONCLUSION: Overall, the rates of severe and/or suppurative OM appeared to be decreasing. However, there is substantial heterogeneity between populations. While better use of available data is informative, it can be difficult to predict rates of severe disease without accurate examination findings. Most memorably, the COVID-19 pandemic had an enormous impact on the research and clinical services for otitis media for most of the period under review. IMPLICATIONS FOR PRACTICE: The use of routinely collected data for epidemiological studies will lead to greater variability in the definitions and diagnostic criteria used. The impact of new vaccines will continue to be important. Some of the lessons learned during the COVID-19 pandemic concerning behaviours that reduce spread of respiratory viruses can hopefully be used to decrease the burden of otitis media in the future. There are still many countries in the world where the burden of otitis media is not well described. In countries where otitis media has been studied over many years, new potential risk factors continue to be identified. In addition, a better understanding of the disease in specific subgroups has been achieved.

The silent reservoir? SARS-CoV-2 detection in the middle ear effusion of patients with Otitis media with effusion after omicron infection.

PURPOSE: This multicenter, prospective study is designed to investigate whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is present in the Middle Ear Effusion (MEE) of patients developing Otitis Media with Effusion (OME) subsequent to an Omicron infection. The objective is to elucidate any potential association between the virus and the condition. METHODS: This study, conducted from January to June 2023, spanned the Otolaryngology departments of two medical institutions in Eastern China. Patients manifesting OME subsequent to Omicron infection from both hospitals were subjected to comprehensive otolaryngological assessments, including pure-tone audiometry (PTA), tympanometry, otoscopic examination, and nasopharyngolaryngoscopy. Subsequently, MEE samples extracted from these patients were analyzed through RT-PCR to detect SARS-CoV-2. RESULTS: In this study, 23 patients (32-84 years; 57.5 ± 14.8 mean age; 47.8 % male) presented OME in 25 ears post-Omicron infection, with 21 (91.3 %) exhibiting unilateral symptoms. The median duration from infection to MEE sampling was 21 days (IQR: 25-46; range: 11-150). Predominantly, 64.0 % exhibited Type B tympanograms, and fluid accumulation was observed in 88.0 % of ears. SARS-CoV-2 was detected in 3 MEE samples (12.0 %), with cycle threshold values ranging between 25.65 and 33.30. CONCLUSIONS: Our study highlights the potential effects of COVID-19 on the middle ear, suggesting a link between SARS-CoV-2 and OME onset. The virus, a significant contributor to OME, is detectable in the MEE nearly a month post-Omicron infection, indicating a potential alteration in OME treatment strategies and a risk of recurrence, emphasizing the necessity for otolaryngologist vigilance.

Cochlear Implantation with a Combined Approach: A Case Report.

Introduction: Ear symptoms of granulomatosis with polyangiitis can range from ear fullness and otalgia to conductive or sensory neural hearing loss and sudden deafness. Cochlear implantation in these patients faces two challenges: access to the round window and control of mastoid and middle ear inflammation. The combined approach in cochlear implantation is a classic trans-facial recess approach facilitated by a trans-canal view. Case Report: In this case report, we present the "combined approach" in a 20-year-old lady with granulomatosis with polyangiitis who underwent cochlear implantation successfully using the combined approach. Conclusion: Post-operative results suggest that the "combine approach" seems to be a safe, easy, and fast cochlear implantation technique for chronic otitis media with an atelectatic middle ear and retracted tympanic membrane or narrow facial recess space. It is a single-stage surgery that has no need for the obliteration of the ear and has less morbidity.
