Abstract
Objectives: This study aimed to characterize the information delivery during preoperative consultations for cholesteatoma removal surgery in 2024. The secondary objective was to identify any factors influencing the information delivered. Methods: This study was a practice survey which included 33 closed-ended questions and 1 open-ended question. Seven questions concerned the participants' characteristics and 2 questions concerned the physiopathology of cholesteatoma. Nine questions focused on surgical information, six questions focused on the procedure modalities and ten questions focused on the risks of complications from the intervention. Results: Eighty-two surgeons answered the survey. In 75% of the cases, an information form written by a professional society was provided. The risk of recurrence or residual post-operative cholesteatoma was systematically stated in 78% of cases (n = 64), while the risk of aesthetic sequelae was only stated in 1% (n = 1). Participants working in a university hospital were more likely to inform patients about the risks of vertigo (p = 0.04), aesthetic risks (p = 0.04), poor functional outcomes (p = 0.04), surgical revision (p = 0.05) and the risk of peripheral facial paralysis (p = 0.05). Surgeons who mainly practiced otology were more likely to inform patients about the risks of recurrence and/or residual cholesteatoma (p = 0.02) and taste disturbances (p = 0.02). Conclusions: Cholesteatoma surgery was well explained to patients during the preoperative consultation, mostly with written support, even if the information given was not the same for all complication risks. It could be useful to create an information form dedicated to cholesteatoma surgery to improve comprehensive information and maintain a trustworthy relationship with patients.

Abstract
OBJECTIVE This study aimed to evaluate the prevalence, incidence, and associated demographic factors of chronic suppurative otitis media (CSOM), utilizing a nationwide healthcare claims database. METHODS This retrospective study utilized outpatient administrative claims data from the IBM MarketScan Research Database from 2007 to 2021. The database (11 246 909 584 claims with 148 147 615 unique patients) includes health data from the private-sector, Medicare/Medicaid, managed care providers, and EMR providers. Included patients had a diagnosis of CSOM based on ICD-9-CM and ICD-10-CM codes. Prevalence and health utilization were estimated by age, gender, and geographic region. RESULTS In the United States, the estimated CSOM prevalence and incidence was 0.46% and 0.03%, respectively. Among CSOM patients (n = 679 906), mean age (SD) was 8.1 (15.4) years, and 52.8% were male. Most patients (81.1%) were aged 0 to 10 years. CSOM prevalence was lower in females (OR = 0.64, 95% CI 0.64-0.65, P < .001), less common in older age (OR = 0.94, 95% CI 0.94-0.94, P < .001), and highest in the South region (OR = 2.08, 95% CI 2.06-2.09, P < .001). CONCLUSION Our results show CSOM prevalence (0.46%) is similar to other developed countries. CSOM prevalence was highest in those aged 0 to 10 years, in males and in the South region. Of note, prevalence and cost are likely significantly underestimated given limitations in accurate ICD-CM coding and the exclusion of uninsured patients. Further epidemiological studies are warranted to characterize the impact of CSOM on the US healthcare system.

Abstract
Otitis media (OM) is a common cause of hearing loss in children that requires corrective surgery. Various studies have investigated the pathomechanisms and treatment of OM. Autophagy, an essential cellular recycling and elimination mechanism implicated in various diseases, is known to play an important role in the pathogenesis of OM. Here, we conducted a literature review on autophagy in OM, highlighting the relationship between expression patterns of autophagy-related factors and pathophysiological and clinical aspects of OM. We summarized the existing research results on the expression of autophagy-related factors in acute OM (AOM), OM with effusion (OME), chronic OM (COM) with cholesteatoma, and COM without cholesteatoma (CholeOM) in animals and humans. Autophagy-related factors are expressed in the middle ear mucosa or fluid of AOM, effusion of OME, granulation tissue of COM, and cholesteatoma of CholeOM. Among ATGs and other autophagy-related factors, the most extensively studied in relation to the pathogenesis of OM are mTOR, LC3II/I, PI3K, Beclin-1, FLIP, Akt, and Rubicon. Expression of autophagy-related factors is associated with AOM, OME, COM, and CholeOM. Inadequate expression of these factors or a decrease/increase in autophagy responses can result in OM, underscoring the critical role of ATGs and related factors in the pathogenesis of OM.

Abstract
OBJECTIVE To clarify the relationship between Eustachian tube dimensions and chronic otitis media aetiology using temporal bone computed tomography. METHODS The data of 231 adults who had undergone surgery for unilateral chronic otitis media were reviewed retrospectively. Diseased and healthy ears were enrolled in groups 1 and 2, respectively. Group 1A included chronic otitis media with cholesteatoma (n = 28) and group 1B included chronic otitis media without cholesteatoma (n = 203). The Eustachian tube dimensions of groups 1 and 2 were compared, to clarify the relationship between the Eustachian tube dimensions and chronic otitis media aetiology. Groups 1A and 1B were compared to assess the effect of Eustachian tube dimensions on cholesteatoma development. RESULTS The Eustachian tube was shorter, narrower and located more horizontally in ears with chronic otitis media. No significant difference was found between groups 1A and 1B. CONCLUSION Eustachian tube dimensions are closely related to chronic otitis media aetiopathology, but are not related to cholesteatoma development.

Abstract
To evaluate the anatomical and functional success rates of palisade cartilage tympanoplasty in chronic otitis media. Thirty patients with chronic otitis media with subtotal perforation underwent palisade cartilage tympanoplasty and were assessed prospectively. The outcomes evaluated were graft uptake and hearing gain. Overall graft uptake was 90% with failure in 3 cases. The preoperative mean air conduction threshold was 22.087 ± 6.120 dB which was improved to 13.387 ± 5.253 dB postoperatively at 12 weeks which was statistically significant. The mean postoperative ABG closure was 8.700 dB with a p value of 0.001 which was statistically significant. Palisade cartilage tympanoplasty demonstrates that subtotal perforations, which are at high risk for graft failure, can be treated efficiently and a durable and resistant reconstruction of the tympanic membrane with reasonable hearing can be achieved.

Abstract
Otitis media is an inflammatory disorder of the middle ear caused by airways-associated bacterial or viral infections. It is one of the most common childhood infections as globally more than 80% of children are diagnosed with acute otitis media by 3 years of age and it is a common reason for doctor's visits, antibiotics prescriptions, and surgery among children. Otitis media is a multifactorial disease with various genetic, immunologic, infectious, and environmental factors predisposing children to develop ear infections. Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis are the most common culprits responsible for acute otitis media. Despite the massive global disease burden, the pathogenesis of otitis media is still unclear and requires extensive future research. Antibiotics are the preferred treatment to cure middle ear infections, however, the antimicrobial resistance rate of common middle ear pathogens has increased considerably over the years. At present, pneumococcal and influenza vaccines are administered as a preventive measure against otitis media, nevertheless, these vaccines are only beneficial in preventing carriage and/or disease caused by vaccine serotypes. Otitis media caused by non-vaccine serotype pneumococci, non-typeable H. influenza, and M. catarrhalis remain an important healthcare burden. The development of multi-species vaccines is an arduous process but is required to reduce the global burden of this disease. Many novel vaccines against S. pneumoniae, non-typeable H. influenza, and M. catarrhalis are in preclinical trials. It is anticipated that these vaccines will lower the disease burden and provide better protection against otitis media. To study disease pathology the rat, mouse, and chinchilla are commonly used to induce experimental acute otitis media to test new therapeutics, including antibiotics and vaccines. Each of these models has its advantages and disadvantages, yet there is still a need to develop an improved animal model providing a better correlated mechanistic understanding of human middle ear infections, thereby underpinning the development of more effective otitis media therapeutics. This review provides an updated summary of current vaccines against otitis media, various animal models of otitis media, their limitations, and some future insights in this field providing a springboard in the development of new animal models and novel vaccines for otitis media.

Abstract
The application of packing agents affects the final surgical outcomes in treating otitis media (OM) and introduces the risk of infection. To decrease the infectious risks of packing agents and even introduce positive bacteriostatic functions, a kind of PPDO-grafted Ag-incorporated TiO2 nanoparticles (Ag@TiO2-PPDO NP)-coated gauzes were prepared by a solution immersion method. Morphologies and in vitro Ag+ releasing of Ag@TiO2-PPDO NP coated gauzes were determined by scanning electron microscope (SEM) and inductively coupled plasma-mass spectrum (ICP-Ms). Ag@TiO2-PPDO NP could respond to visible light, which might make Ag@TiO2-PPDO NP inhibit the proliferation of bacteria continually and positively with irradiation of visible light. Then the bacteriostatic effects of these gauzes on OM pathogens were investigated in vitro and in vivo. These gauzes could inhibit the proliferation of pathogenic Staphylococcus aureus (S. aureus) and Streptococcus pneumoniae (S. pneumoniae) in vitro and rat subcutaneous infection models. Specifically, the bacteriostatic effect of these gauzes on S. aureus and S. pneumoniae could be enhanced with irradiation by visible light in vitro. Further, the rat external auditory canal infection model verified the enhanced bacteriostatic effect of Ag@TiO2-PPDO-coated gauzes on S. aureus with irradiation by visible light. The Ag@TiO2-PPDO-coated gauzes are promising for packing materials after OM surgery and could reduce postoperative antibiotic requirements.

Abstract
Otitis media is a significant contributor to healthcare visits and the prescription of drugs. Its associated complications and consequences pose the primary factors for preventable hearing impairment, especially in developing nations. Chronic suppurative otitis media (CSOM) is prevalent among children globally as one of the commonest chronic infectious diseases during childhood. The subsequent complications and sequelae play a central role in causing avoidable hearing loss, particularly within developing countries. In addition to impaired hearing, this condition can lead to severe health complications, such as issues involving the intracranial region. Despite the involvement of microbial, immunological, and genetic factors as well as Eustachian tube characteristics, in the development of CSOM, there remains a need for further elucidation regarding its pathogenesis. Based on its microorganisms, the treatment of choice will be affected to prevent further complications in the child. The primary approach to treating acute otitis media (AOM) involves effectively addressing ear pain and fever symptoms, while antibiotics are only administered in cases where children experience severe, long-lasting, or frequent infections. Despite the extensive investigation on AOM pathogenesis, research is scarce regarding CSOM. Given that antibiotic resistance and drug-induced ear damage are growing problems and surgery-related complications, it is imperative to devise effective therapeutic interventions against CSOM arises. Therefore, comprehending the host's immune function concerning CSOM and identifying how bacteria sidestep these potent responses becomes crucial. Acquiring insight into molecular mechanisms associated with CSOM will enable scientists to formulate innovative treatment approaches to combat this disease, thereby averting hearing loss consequences. The management consists of watchful waiting, primarily for children with chronic effusions and hearing loss.

Abstract
To compare results of inlay and overlay cartilage-perichondrium composite graft myringoplasty. The present study was conducted in the department of otorhinolaryngology, Pt. B. D. Sharma PGIMS, Rohtak. The study was conducted on 40 patients of either sex in age group of 15-50 years having unilateral or bilateral inactive (mucosal) chronic otitis media with dry ear over a period of at least 4 weeks without use of topical or systemic antibiotics after obtaining their informed and written consent. Mean age in group I was 25.25 ± 7.27 years and in group II was 25.95 ± 9.06 years. Maximum number of patients in both groups were in the age group 15-24 years. Out of the total patients, 60% were males and 40% were females. At 6 months post operatively, 95% cases in group I had successful graft take-up compared to 85% cases in group II. However, at long term follow up for 24 months, graft success rate was statistically significant in group I. In group I, 100% graft uptake was seen in large size perforation of 4 and 5 mm along with 2 mm as compared to group II, with 100% graft uptake for only small size perforation of 2 mm. The mean hearing threshold gain was 16.50 ± 5.52 dB in group I as compared to 13.03 ± 6.44 dB in group II. Mean postoperative improvement in air bone (AB) gap of 16.50 ± 5.52 dB was seen in group I as compared to 13.07 ± 6.44 dB seen in group II. The graft take up rate was found to be better in long term with inlay cartilage- perichondrium composite graft myringoplasty technique compared to over lay technique with both the groups showing significant hearing improvement post-operatively. This high success rate for graft uptake and ease to perform under local anaesthesia makes in-lay cartilage perichondrium composite graft myringoplasty technique relatively optimal to use for office based myringoplasty.

Nicholas Jungbauer W, Jeong S, Nguyen SA, Lambert PR. Comparing Myringoplasty to Type I Tympanoplasty in Tympanic Membrane Repair: A Systematic Review and Meta-Analysis. Otolaryngol Head Neck Surg 2023; 168:922-934. [PMID: 36939595 DOI: 10.1002/ohn.191] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Revised: 10/10/2022] [Accepted: 10/18/2022] [Indexed: 02/11/2023]
Abstract
OBJECTIVE To compare the anatomic success rates of type I tympanoplasty (tympanoplasty) versus myringoplasty. By our definition, tympanoplasty involves entering the middle ear via elevation of a tympanomeatal flap, while myringoplasty involves surgery to the drumhead without middle ear exposure. DATA SOURCES PubMed, Scopus, CINAHL, Cochrane. REVIEW METHODS To be included, studies must have documented surgical technique, tympanic membrane (TM) perforation size (as % of TM), and success rate using tissue or alloplastic grafts. Exclusion criteria included series with more than 10% of patients with cholesteatoma or middle ear pathology. A meta-analysis of weighted summary proportions under the random effects model was performed, and proportion differences (PD) were calculated. A secondary analysis of hearing outcomes was performed. RESULTS Eighty-five studies met inclusion, with a tympanoplasty cohort of n = 7966 and n = 1759 for myringoplasty. For perforations, less than 50% of the TM, the success rate for tympanoplasty and myringoplasty was 90.2% and 91.4%, respectively (PD: 1.2%, p = .19). In perforations greater than 50%, tympanoplasty and myringoplasty success rates were 82.8% and 85.3%, respectively (PD: 2.5%, p = .29). For both procedures, perforations less than 50% of the TM had higher success rates than perforations greater than 50% of the TM (p < .01). Both techniques endorsed significant improvements to air-bone gap (ABG) metrics. CONCLUSION Our analysis suggests that the anatomic success rate is similar for tympanoplasty and myringoplasty, regardless of perforation size, and that smaller perforations experience higher success rates in both techniques. ABG outcomes were also similar between procedure techniques.

Abstract
Chronic otitis media, inactive mucosal disease needs surgical treatment for complete relief from symptoms like hearing loss and discharging ear. There are various surgical approaches mentioned in literature; among which postauricular microscopic tympanoplasty is the most commonly used. With optics advancements, endoscopic surgeries are gaining more popularity due to reduced operative time, less post-operative pain, better cosmesis and reduced hospital stay. To study the clinical profile of patients with chronic otitis media inactive mucosal disease and compare conventional postauricular microscopic tympanoplasty to transcanal endoscopic tympanoplasty on the basis of operative time, postoperative pain, subjective cosmesis, postoperative complications and postoperative hearing gain. 60 patients of chronic otitis media inactive mucosal type, coming in our out-patient department over 2 years and willing to participate were taken for surgery. Patients were divided into 2 groups of 30 each by computerized random technique. Group A underwent conventional postauricular microscopic tympanoplasty and Group B underwent transcanal endoscopic tympanoplasty. Patients were evaluated on the basis of intraoperative time, postoperative pain score, postoperative complications, subjective cosmesis and postoperative hearing gain. Tympanoplasty by transcanal endoscopic approach had better outcomes in terms of less intraoperative time, less postoperative pain, less postoperative complications, and better subjective cosmetic outcome. Postoperative hearing gain (ABG) in both the groups was similar. Endoscopic tympanoplasty has many advantages over microscopic tympanoplasty as it is a natural access point to tympanic membrane and middle ear cleft. It preserves most of normal anatomy by minimizing dissection of bone and soft tissue. It is possible to obtain a wide angle and a magnified view of the operating field using endoscope with minimum manipulation. Therefore endoscope can be a good alternative of microscope for tympanoplasty.

Abstract
To compare efficacy of temporalis fascia myringoplasty using platelet-rich plasma(PRP) {MP-PRP} and conventional emporalis fascia myringoplasty (MP-C) in treatment of moderate to large central tympanic-membrane(TM) perforation. Randomized-Control-Trial. We randomly assigned eighty-patients with COMmucosal-type with medium to large central TM-perforation and conductive hearing loss planned for primary myringoplasty to receive either MP-PRP orMP-C. Myringoplasty was performed through postauricular approach underlay graft using temporalis fascia. Primary-outcome was graft uptake (an intact TM) at 6 months postoperatively. Secondary-outcome was the postoperative hearing improvement measured by pure-tone-audiometry (PTA). Eighty-myringoplasties (MP-PRP group-40, MP-C group-40) done for 80 patients (male = 41; female = 39, age-group = 18-45-years) were included in analysis. At 6 months postoperatively graft uptake rate was 94.4% in MP-PRP and 92.1%% in MP-C group. There was no statistically significant difference in graft-uptake between the two groups (p = 0.358). Success in terms of hearing gain (≥ 10 dB) was achieved in 34 patients (89.5%) in MP-C and 37 patients (94.9%) in MP-PRP group. At 6 months follow-up; mean-PTA-average improved from 35.10 ± 5.401 dB to 27.74 ± 5.660 dB and mean ABG improved from 24.00 ± 5.204 dB to17.42 ± 5.559 dB in MP-C group. At 6 months followup; mean-PTA-average improved from 37.00 ± 6.144 dB to 26.65 dB and mean air bone gap (ABG) improved from 25.98 ± 5.736 dB to 16.21 ± 4.318 dB in MP-PRP group. No statistically significant differences in improvement in PTA-values were observed between both groups (p = 0.336).Postoperative complications were similar in both groups. Graft-uptake, hearing outcomes and complications of MP-PRP were similar to MP-C. MP-PRP offers no advantages over MP-C for treatment of TM perforation.

Abstract
Cholesteatoma is a potentially serious complication of chronic ear infections and requires surgical intervention for definitive management. Long-term complications include a frequent need for repeat surgical intervention for disease recurrence, and techniques to improve efficacy of single-stage surgery are an important area of continued research. This study investigates a novel application of the photosensitizer immune conjugate (PIC) cetuximab-benzoporphyrin derivative (Cet-BPD) for in vitro localization of human cholesteatoma tissue, coupled with an in vivo safety study for middle ear application of Cet-BPD in a murine model. In fresh human cholesteatoma tissues, Cet-BPD demonstrates selective localization to the hyperplastic squamous cell tissue associated with cholesteatoma, without localizing to other tissues such as middle ear mucosa. Applied to the murine middle ear, Cet-BPD does not demonstrate any deleterious effect on murine hearing when assessed by any of auditory brainstem response (ABR) thresholds, distortion product otoacoustic emission thresholds, or ABR wave I amplitudes. These findings demonstrate the technical promise and encouraging safety profile for the use of PICs for intraoperative localization and treatment of cholesteatoma.

Measurement of hearing impairment among Greenlandic school-children: association between self-reported data and clinical examinations. BMC Pediatr 2022; 22:618.

Abstract
Background Multiple ear infections is causing hearing impairment among children all over the world and the health and social consequences track into early adolescence and later in life, if not treated. The monitoring of prevalence in a population is important to assess the need for interventions in a population. Methods One hundred eighty five children from 5 to 10th grade from Sisimiut town and the nearby settlements participated in a clinical examination to have ear-examination and pure tone audiometry. Participants filled out a questionnaire at home with their parents before the clinical examination, and hearing impairment was collected as individual self-reports and as audiometric measurements. Results A total of 185 children between 9 and 15 years of age (median: 11 years, IQR: 10–13) were included, 60% (n = 111) were girls. 247 (70%) of the 355 available otoscopies were clinically assessed as normal. Cohen’s Kappa coefficient was 0.31. Eighteen children (10%) were found to have hearing impairment. None of the children had hearing aids. Test performance for self-reports were that sensitivity was 56% and specificity was 87%. The predictive value of a positive test was 31%, and the predictive value of a negative test was 95%. 32 children (17%) reported hearing impairment to the extent that they were not able to keep up in school, of which half reported that it had lasted for more than one year. 7 of the 32 children reporting hearing impairment (22%) reported that the extent of their hearing impairment was affecting their classroom experience so they were not able to follow. Conclusion Self-reported and clinically screening for hearing impairment are two different concepts. Even though the two concepts are statistically correlated, the correlation coefficients are low. The test performance indicated that self-reported data might be measuring hearing as an experience in a social environment and not directly comparable to pure tone audiometry which examines hearing in controlled testing conditions. Since both measure hearing impairment, they supplement each other in research on impaired hearing, and the choice of measure should relate to the purpose and method of the investigation.

Abstract
AbstractObjectiveThis study investigated the relationship between physical dimensions of the Eustachian tube and the emergence of primary attic cholesteatoma.MethodsA total of 31 patients with unilateral attic cholesteatoma were selected for radiological comparison. Standard point measurements as well as specific measurements were performed using imaging software. The length, narrowest diameter and bony segment volume, and pharyngeal orifice diameter of both sides of the Eustachian tube (attic cholesteatoma and healthy control ears) were measured and compared.ResultsComparison of the values did not reveal any statistically significant difference between the attic cholesteatoma ears and the healthy control ears in terms of: Eustachian tube height, narrowest diameter, bony segment volume or pharyngeal orifice diameter.ConclusionNo statistically significant difference was found between the cholesteatoma ears and the healthy control ears in terms of the osseous Eustachian tube size. The findings indicate that the Eustachian tube bony segment dimensions and pharyngeal orifice diameter are not factors in attic cholesteatoma development.

Abstract
Introduction and importance Chronic suppurative otitis media (CSOM) is a chronic inflammation of the middle ear associated with tympanic membrane rupture and purulent discharge for at least 6 weeks. Owing to the proper use and easy availability of antibiotics, these types of cases are rare in developed regions, but they are still occasionally seen in the developing world with poor hygiene and a lack of availability of antibiotics and immunizations. Case presentation Patient presented with complaints of headache, yellow-colored discharge from ear, fever and vomiting. The patient's Glasgow Coma Scale (GCS) was 12/15, neck stiffness and positive Kernig's sign, horizontal nystagmus and exaggerated deep tendon reflexes. Positive CSF findings and Magnetic Resonance Imaging showing right sided cerebellar abscesses, led to the diagnosis of right-sided CSOM leading to cerebellar brain abscess. Patient was treated with anti-pyrectics, intravenous mannitol, IV and topical antibiotics and IV-dexamethasone. Abscess evacuation was performed in neurosurgery department while mastoidectomy was performed in ENT department. Patient's condition improved quickly and was discharged with regular follow-up. Discussion CSOM is a long-standing middle ear infection, associated with ear discharge and permanent perforation of the tympanic membrane. Divided into two main types, a) Tubo tympanic b) Atticoantral. CSOM occasionally presents with severe intracranial complications, especially in developing countries. Conclusion CSOM is a chronic inflammation of the middle ear. Without early and effective management, it can lead to serious intracranial complications. So, diagnosis of complications like cerebellar abscess should be on the differential while dealing with patients with CSOM in developing countries. CSOM is a chronic inflammation of the middle ear associated with tympanic membrane rupture and purulent discharge for at least 6 weeks. Commonly seen complications include infections leading to auricular sinus, subperiosteal abscess and meningitis. This case report deals with discussion of a patient who presented with symptoms of meningoencephalitis and cerebellar brain abscess.

Abstract
AbstractBackgroundThe aggressiveness of paediatric cholesteatoma has long been a matter of debate. While much of the evidence is substantiated by data from the Western world, it is further limited by the retrospective nature of most studies. Therefore, this paper presents a comparative analysis of various characteristics of cholesteatoma between paediatric and adult populations seen at our centre.MethodsA total of 50 patients (25 adults and 25 paediatric) with clinical diagnosis of chronic suppurative otitis media with cholesteatoma underwent canal wall down mastoidectomy over a period of two years. The intra-operative findings were noted and patients were followed up for six months.ResultsThere was more extensive spread and ossicular erosion in paediatric cases. However, complications such as facial canal dehiscence and lateral semicircular canal dehiscence were more common in adults.ConclusionPaediatric cholesteatoma is more aggressive and invasive than adult cholesteatoma, and the clinical behaviour is consistent with findings from other parts of the world.

Abstract
Eustachian tube (ET) dysfunction is known to be a cause for various middle ear diseases. Dynamic slow motion videoendoscopy (DSVE) and impedance audiometry (IA) can both be employed to evaluate ET dysfunction. To assess the role of DSVE and IA for diagnosing ET dysfunction in cases of middle ear disorders. It is a prospective case control study. 102 ears with chronic otitis media were taken as cases and 102 healthy ears as controls. IA and DSVE were performed to assess ET function in both the groups. Sensitivity/ specificity of both the diagnostic tests were evaluated in case and control groups. Out of 102 ET of case group exposed to both tests, 87 were found to have ET dysfunction by DSVE and 80 by IA. Among 102 ET of control group 78 were identified as normal by DSVE while 87 by IA. On applying chi square test in both these groups, the associations were significant. (p value < 0.0001). Patients with grade 2B or higher on DSVE endoscopy had abnormal IA findings, indicating that higher the grade on DSVE, higher the chance of abnormal IA. DSVE and IA are potentially useful tools in evaluation of cases of COM and which provide information regarding functional and pathological factors responsible for ET dysfunction.

Abstract
Purpose Injury or inflammation of the middle ear often results in the persistent tympanic membrane (TM) perforations, leading to conductive hearing loss (HL). However, in some cases the magnitude of HL exceeds that attributable by the TM perforation alone. The aim of the study is to better understand the effects of location and size of TM perforations on the sound transmission properties of the middle ear. Methods The middle ear transfer functions (METF) of six human temporal bones (TB) were compared before and after perforating the TM at different locations (anterior or posterior lower quadrant) and to different degrees (1 mm, ¼ of the TM, ½ of the TM, and full ablation). The sound-induced velocity of the stapes footplate was measured using single-point laser-Doppler-vibrometry (LDV). The METF were correlated with a Finite Element (FE) model of the middle ear, in which similar alterations were simulated. Results The measured and calculated METF showed frequency and perforation size dependent losses at all perforation locations. Starting at low frequencies, the loss expanded to higher frequencies with increased perforation size. In direct comparison, posterior TM perforations affected the transmission properties to a larger degree than anterior perforations. The asymmetry of the TM causes the malleus-incus complex to rotate and results in larger deflections in the posterior TM quadrants than in the anterior TM quadrants. Simulations in the FE model with a sealed cavity show that small perforations lead to a decrease in TM rigidity and thus to an increase in oscillation amplitude of the TM mainly above 1 kHz. Conclusion Size and location of TM perforations have a characteristic influence on the METF. The correlation of the experimental LDV measurements with an FE model contributes to a better understanding of the pathologic mechanisms of middle-ear diseases. If small perforations with significant HL are observed in daily clinical practice, additional middle ear pathologies should be considered. Further investigations on the loss of TM pretension due to perforations may be informative.

Comparative analysis of moderate and severe tympanic membrane retractions in children and adults. Int J Pediatr Otorhinolaryngol 2021; 147:110784. [PMID: 34058531 DOI: 10.1016/j.ijporl.2021.110784] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Revised: 04/19/2021] [Accepted: 05/17/2021] [Indexed: 11/22/2022]
Abstract
OBJECTIVE Owing to the limited literature demonstrating the correlation between the degree of severity of retractions and the degree of hearing loss in children and adults, the study aimed to compare the differences in the location, the severity, and the air-bone gap (ABG) of tympanic membrane (TM) retractions in children and adults. METHODS Cross-sectional study, in a tertiary hospital. Consecutive patients with moderate or severe TM retractions (661 ears) between August 2000 and January 2019 were evaluated. The average age (mean ± standard deviation) was 11.7 ± 3.3 years among pediatric patients (42.4%) and 46.4 ± 5 years among adults (57.6%). Video-otoscopy and pure tone audiometry were performed in all patients. The main outcome measures were the locations of retractions, their prevalence, and their severity; ABG thresholds measured at the 4-frequency pure-tone average (PTA). RESULTS The prevalence of pars flaccida (PF) retractions was higher in adults, while that of pars tensa (PT) was higher in children (p = 0.00). The degree of severity was similar between children and adults for isolated PF and PT retractions (p = 0.37 and p = 0.10, respectively). Effusion was similar in children (27.8%) and adults (33.3%). The median decibel hearing level (dB HL) (minimum-maximum) of the ABG PTA was 13.75 dB (0-57.5 dB HL) in children and 13.75 dB (0-58.7 dB) in adults (p = 0.48). There was no difference in the size of the ABG PTA between children and adults (p = 0.71), and in ABG size for isolated PF retractions (p = 0.14), PT retractions (p = 0.35), and association of PF and PT retractions (p = 0.56). CONCLUSION PT retractions were more prevalent in children and PF retractions in adults. There was no difference between the two groups based on the severity of the retraction. The size of the air-bone gaps was similar in children and adults.

Abstract
BACKGROUND Evidence to support potential links between chronic otitis media (COM) and vestibular impairment/postural balance control issues is lacking. OBJECTIVE To investigate whether COM associates with vestibular symptoms, balance problems, and abnormalities in vestibular function tests. METHODS We selected 126 patients with COM and excluded patients with any identifiable underlying causes for vestibular dysfunction. Fifty-two healthy volunteers were included as controls. All subjects underwent anamnesis, physical examination, posturography, and video-head impulse tests. RESULTS We found a high prevalence of vestibular symptoms (58.4%) among patients with COM, while only 2% of the controls had vestibular symptoms. There was a positive correlation between COM activity with the presence of tinnitus and vestibular symptoms (P < 0.05). Clinical vestibular tests were abnormal in 63% of patients with COM, and those positively associated with presence of vestibular symptoms. Posturography results shown worse postural balance control in patients with COM as compared with controls, especially in the limit of stability (LOS) (Mean LOS, COM = 157.56 cm2; controls = 228.98 cm2; p < 0.001) and worse results in the test with eyes closed while standing on a foam mattress (sway area, COM = 10.91 cm2; controls = 5.90 cm2; p < 0.001) in patients with COM as compared with controls. We did not observe differences in the average vestibuloocular reflex gains in the video-head impulse test between our COM and control groups. CONCLUSIONS Our results show that COM associates with higher prevalence of vestibular symptoms and abnormalities in clinical vestibular function tests, and worse postural control as compared with controls. Among patients with COM, the activity of the middle-ear inflammation seemed to positively associate with the severity of hearing and balance problems.

Abstract
OBJECTIVE This study aimed to analyse social, health and environmental factors associated with the development of chronic otitis media by age nine. METHOD This was a prospective, longitudinal, birth cohort study of 6560 children, reviewed at age nine. Chronic otitis media defined as previous surgical history or video-otoscopic changes of tympanic membrane retraction, perforation or cholesteatoma. Non-affected children were used as the control group. RESULTS Univariate analysis demonstrated an association between chronic otitis media and otorrhoea, snoring, grommet insertion, adenoidectomy, tonsillectomy, hearing loss, abnormal tympanograms and preterm birth. Multivariate analysis suggests many of these factors may be interrelated. CONCLUSION The association between chronic otitis media and otorrhoea, abnormal tympanograms and grommets supports the role of the Eustachian tube and otitis media (with effusion or acute) in the pathogenesis of chronic otitis media. The role of snoring, adenoidectomy and tonsillectomy is unclear. Associations suggested by previous studies (sex, socioeconomic group, parental smoking, maternal education, childcare, crowding and siblings) were not found to be significant predictors in this analysis.

Abstract
Acute otitis media (AOM) is the main indication for pediatric antibiotic prescriptions, accounting for 25% of prescriptions. While the use of topical drops can minimize the administered dose of antibiotic and adverse systemic effects compared to oral antibiotics, their use has limitations, partially due to low patient compliance, high dosing frequency, and difficulty of administration. Lack of proper treatment can lead to development of chronic OM, which may require invasive interventions. Previous studies have shown that gel-based drug delivery to the ear is possible with intratympanic injection or chemical permeation enhancers (CPEs). However, many patients are reluctant to accept invasive treatments and CPEs have demonstrated toxicity to the tympanic membrane (TM). We developed a novel method of delivering therapeutics to the TM and middle ear using a topical, thermoresponsive gel depot containing antibiotic-loaded poly(lactic-co-glycolic acid) microspheres. Our in vitro and ex vivo results suggest that the sustained presentation can safely allow therapeutically relevant drug concentrations to penetrate the TM to the middle ear for up to 14 days. Animal results indicate sufficient antibiotic released for treatment from topical administration 24h after bacterial inoculation. However, animals treated 72h after inoculation, a more clinically relevant treatment practice, displayed spontaneous clearance of infection as is also often observed in the clinic. Despite this variability in the disease model, data suggest the system can safely treat bacterial infection, with future studies necessary to optimize microsphere formulations for scaled up dosage of antibiotic as well as further investigation of the influence of spontaneous bacterial clearance and of biofilm formation on effectiveness of treatment. To our knowledge, this study represents the first truly topical drug delivery system to the middle ear without the use of CPEs.

Abstract
OBJECTIVES Primary: to compare, in vitro, the antimicrobial activity of different antiseptic agents versus quinolone drops, against the common organisms of chronic otitis media.Secondary: to examine the possible role of pH on the antimicrobial activity of the antiseptic solutions. METHODS Three antiseptic powders (boric acid; iodine; and a 1:1 combination of these two) and four solutions (2% boric acid; 2% acetic acid; 3.25% aluminum acetate; and 5% povidone iodine) were tested against five bacteria and two fungi common in chronic otitis media, using both agar plates and the modified broth dilution method. These results were compared with the antimicrobial activity of quinolone drops.The potential role of pH of solutions was tested by reducing the acidity of the agents and repeating the broth dilution. RESULTS Of the powders, iodine, and iodine/boric acid combined, are very effective against all organisms. Boric acid powder showed moderate effectiveness against all organisms. All solutions performed poorly on the agar plates. 5% povidone iodine has good effectivity when tested with the broth dilution method. 3.25% aluminum acetate had the best activity against Pseudomonas aeruginosa. CONCLUSION Boric acid powder and 5% povidone iodine solution show promise for clinical use. Boric acid powder has proven clinical effectiveness. 5% povidone iodine requires further clinical research. Although very effective in vitro, iodine powder is toxic to tissues and cannot be recommended for clinical use. The pH of solutions does not seem to play a significant role in their antimicrobial activity in vitro.

Abstract
OBJECTIVE Hearing loss is an important health concern in Canada's Arctic. The objective of this research was to provide information on the prevalence of childhood hearing loss in Nunavut. DESIGN This cross-sectional study involved comprehensive audiologic assessments of school-aged children in six communities to determine overall and community-specific prevalence of hearing loss. Data were collected about hearing aid use and factors affecting use through a parent questionnaire. STUDY SAMPLE Assessments were completed for 644 children in kindergarten to grade 6. RESULTS 124 (19.3%) children had hearing loss of ≥ 30 dB HL at one or more frequencies in at least one ear (93.5% conductive loss). Applying a Canadian prevalence study definition, 148 (23.5%) children had hearing loss. Tympanic membrane perforations were present in 36.8% (n = 28) of children with unilateral and 45.8% (n = 22) with bilateral loss. CONCLUSIONS The prevalence of hearing loss in Canada's North was almost three times that reported for non-indigenous children. One in five school-aged children was found to have hearing loss that is likely to affect classroom learning and social/emotional development. A hearing health strategy tailored to this population is critically needed.

Self-reported hearing impairment among Greenlandic adolescents: Item development and findings from the Health Behaviour in School-aged Children study 2018. Int J Pediatr Otorhinolaryngol 2019; 126:109629.

Abstract
OBJECTIVES Ear infections are the leading cause of hearing impairment among children worldwide and a major public health problem in many indigenous populations, yet representative studies of self-reported hearing impairment are currently scarce. The purpose of the present study was therefore two-sided; first to develop an item bank for the collection of data on hearing impairment among Greenlandic adolescents, and second to report data on the child reports on hearing impairment from a national questionnaire-based survey. METHODS The study describes the process of developing items measuring hearing impairment among schoolchildren, and reports data for their inclusion into a national questionnaire survey. The data formed part of the Health Behaviour in School-aged Children (HBSC Greenland) 2018 survey including 2,273 students, corresponding to 47.6% of all Greenlandic schoolchildren in the age range from 10 to 16 years. Data analyses performed describe the data characteristics and the frequency of self-reported hearing impairment among Greenlandic schoolchildren. Binary logistic regression examined the associations of hearing impairment on school-related (risk) factors and self-rated health. RESULTS An average of 4% reported experiencing ear pain almost daily, and almost 10% reported ear pain at least weekly. Moreover, 3% reported having inflammation in the ear at least weekly, and 5% reported to have such impaired hearing that they were not at all able to follow what happened in school. Logistic regression showed that girls had significantly higher odds of low self-rated health, poor school environment and academic achievement below average when they had experienced impaired hearing. All ORs were statistically significant, varying from 1.85 (95% CI: 1.16-2.94) for low self-rated health, to 3.05 (95% CI 1.83-5.11) for feeling pressured by schoolwork. For boys the only significant association with impaired hearing was an academic achievement below average of 1.73 (95% CI 1.08-2.77). CONCLUSIONS The study confirms clinical knowledge and case studies that there are a significant proportion of Greenlandic adolescents who have experienced impaired hearing. Future studies may use questionnaire data to follow up on children with hearing impairment to be able to report changes over time and associations to school-related and social factors.

Abstract
OBJECTIVES To evaluate clinical characteristics of tympanosclerosis and to investigate the predictive value of clinical evaluation in diagnosing the ossicular chain status in tympanosclerosis. METHODS The study included 166 ears operated on for chronic otitis media. Age, gender, duration of symptoms and history of ear drainage were recorded from the patient's file. Details of ossicular mobility were obtained from the operation records. RESULTS There was no difference in age or disease duration between ears with chronic otitis media with or without tympanosclerosis. The ears with chronic otitis media without tympanosclerosis had a higher rate of middle-ear suppuration compared to those with tympanosclerosis (p < 0.001). In chronic otitis media with tympanosclerosis, the ears with a mobile ossicular chain had a higher rate of active drainage in their clinical history compared to ears with a fixed ossicular chain (p = 0.026). Stapes fixation was present mostly in dry ears with tympanosclerosis (p = 0.005). CONCLUSION Chronic otitis media with tympanosclerosis is characterised by the long-term absence of suppurations. The probability of having a fixed ossicular chain or stapes was higher in tympanosclerosis cases with no ear drainage.

Abstract
We present a case of a male Italian patient of 66 years with a history of kidney transplantation in treatment with cyclosporine and methylprednisolone. He visited an ENT clinic and was diagnosed as chronic left purulent otitis media. He began at-home antibiotic therapy with poor benefit. On 09/13/18, he was admitted to the hospital "S. Maria "of Terni for persistence of left ear pain and complete hearing loss. Magnetic resonance imaging (MRI) of the brain showed "in correspondence of the petrous rock and the mastoid…presence of flogistic tissue." Auricular swabs and later surgical drainage of the purulent material were performed and both were positive for extensively drug-resistant (XDR) Pseudomonas aeruginosa sensitive only to colistin in absence of synergism with rifampin. The patient underwent antibiotic therapy with ceftolozane-tazobactam, a new generation cephalosporin with anti-Pseudomonas activity and a β-lactamase inhibitor, that currently is indicated for the treatment of complicated urinary tract infections and complicated intra-abdominal infections, with complete healing. In literature, it is described a series of 12 patients with severe MDR (multidrug-resistant) Pseudomonas aeruginosa infections (6 pneumonia) who received salvage therapy with ceftolozane-tazobactam after inappropriate empirical and/or suboptimal treatment. This study included a case of a male patient of 45 years, affected by Burkitt lymphoma and severe neutropenia, who presented with otitis and mastoiditis, and isolation of Pseudomonas aeruginosa in surgical drainage of the purulent material of the ear (blood cultures were negative). He underwent antibiotic therapy with ceftolozane-tazobactam at a dosage of 3 g/8 h for 21.3 days. The patient was healed, but a late recurrence was described because of isolation of ceftolozane-tazobactam-resistant Pseudomonas after therapy. The possibility of acquiring resistance to ceftolozane-tazobactam should be considered in patients with previous exposure to beta-lactams and with poor response to these antibiotics.

Abstract
OBJECTIVE There are scant recent studies from low middle-income countries that investigate the impact of otitis media (OM) on hearing loss (HL) in school children. METHODS This was a prospective epidemiological survey conducted by otorhinolaryngologists and audiologists in a sample of 7005 public school children (6-15 years) from 6 urban and rural sub-districts, in Indonesia. Children with otoscopic abnormalities or who failed a hearing-screening test conducted at school, underwent diagnostic audiometry and tympanometry. RESULTS OM was detected in 172 children (2.5%), acute otitis media - AOM (17%), otitis media with effusion - OME (15%), and chronic suppurative otitis media - CSOM (67%). The overall rate of HL in the school children was 181/10,000, which was almost three-fold higher in rural (273/10,000) than urban areas 92.6/10,000. OME accounted for much of the mild HL, while CSOM accounted for most of the moderate HL. There was a significantly higher rate of OM related HL in rural areas (116.2/10,000), than in urban areas (47.4/10,000), p = 0.002. OM related disabling HL was found at a rate of 44.2/10,000, mostly due to CSOM (37.1/10,000). CONCLUSION Otitis media contributed to 57% of all HL in school children, and posed a significant burden on Indonesian school children. Most of the disabling HL was due to CSOM. Efforts to find these children and offer ear and hearing care are important.

OBJECTIVE To report the presentation, diagnosis, management, and convalescence of labyrinthine sequestrum (LS) and summarize all previously published cases. PATIENT(S) Eleven-year-old female with LS. INTERVENTION(S) Multidisciplinary diagnostic evaluation and treatment. MAIN OUTCOME MEASURES Imaging and laboratory findings, medical and surgical treatment. RESULTS We describe a case of LS secondary to medically recalcitrant suppurative otitis media in an 11-year-old female and review all eight previously reported cases. The index patient presented after 6 months of otitis media, profound unilateral hearing loss, with symptoms suggesting meningitis. Temporal bone CT demonstrated marked bony destruction of the left otic capsule. Gadolinium-enhanced MRI showed an enhancing process with evidence of meningitis and subdural empyema. The patient was treated with surgical debridement and culture directed antibiotic therapy. Posttreatment imaging showed resolution of intracranial infection with fibrous bony healing of the otic capsule resembling fibrous dysplasia. CONCLUSION LS is a rare form of labyrinthitis characterized by centrifugal destruction of the otic capsule. The current index case highlights the importance of combined medical and surgical treatment and describes for the first time in the literature the fibrous ossification of the otic capsule following disease resolution.

Optical coherence tomography (OCT) has a micro-resolution with a penetration depth of about 2 mm and field of view of about 10 mm. This makes OCT well suited for analyzing the anatomical and internal structural assessment of the middle ear. To study the vibratory motion of the tympanic membrane (TM) and its internal structure, we developed a phase-resolved Doppler OCT system using Kasai’s autocorrelation algorithm. Doppler optical coherence tomography is a powerful imaging tool which can offer the micro-vibratory measurement of the tympanic membrane and obtain the micrometer-resolved cross-sectional images of the sample in real-time. To observe the relative vibratory motion of individual sections (malleus, thick regions, and the thin regions of the tympanic membrane) of the tympanic membrane in respect to auditory signals, we designed an experimental study for measuring the difference in Doppler phase shift for frequencies varying from 1 to 8 kHz which were given as external stimuli to the middle ear of a small animal model. Malleus is the very first interconnecting region between the TM and cochlea. In our proposed study, we observed that the maximum change in Doppler phase shift was seen for the 4 kHz acoustic stimulus in the malleus, the thick regions, and in the thin regions of the tympanic membrane. In particular, the vibration signals were higher in the malleus in comparison to the tympanic membrane.

A novel gel patch for minimally invasive repair of tympanic membrane perforations. Int J Pediatr Otorhinolaryngol 2018; 115:27-32. [PMID: 30368387 DOI: 10.1016/j.ijporl.2018.09.012] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2018] [Revised: 09/12/2018] [Accepted: 09/12/2018] [Indexed: 01/05/2023]
Abstract
OBJECTIVE Evaluate the efficacy of a photocrosslinkable gel patch for repairing tympanic membrane (TM) perforations using a minimally invasive procedure. METHODS 38 adult male chinchillas underwent bilateral TM perforation via CO2 laser (n = 76 TMs). Eight weeks post-perforation induction, either a gel patch (n = 26) or EpiDisc (n = 12) was applied to the perforation through the ear canal. Perforation margins were not abraded prior to gel patch application in order to make the procedure minimally invasive. During the study, the application process was refined, and 9 of 26 gel-treated TMs received a second gel-patch augmentation. Perforations were observed for 14 weeks post-treatment to determine healing rates, after which animals were euthanized and their TMs and cochlea removed for histological analysis. RESULTS 38 perforations (50%) persisted for 8 weeks without manipulation. Healing rates stabilized within three weeks post-treatment. Of the gel-treated TMs, 14 TMs healed after one application, 7 TMs healed after a second application, and 5 TMs did not heal, yielding an 81% total healing rate. Six of 12 EpiDisc-treated TMs healed (50%). There was no statistical difference (p = 0.06) in perforation size between gel-treated (25.1 ± 12.5% total TM area) and Epidisc-treated (36.4 ± 22.5). The largest perforation healed with gel patch was 60% total TM area. Histological analysis showed gel-treated TMs to have trilaminar regeneration with substantial lamina propria thickness. Gel-treated TMs had thickness of statistical equivalence to untreated TMs (47.1 ± 29.0 and 54.8 ± 12.1 μm, respectively (p = 0.40)). EpiDisc-treated TMs showed a cell monolayer of substantially less thickness (9.04 ± 6.26 μm, p < 0.05) than gel-treated TMs. No evidence of ototoxicity was present in cochlea from either gel patch or Epidisc treatment. CONCLUSIONS The gel is promising regarding thickness and trilaminar regenerated tissue, perhaps due to the biomechanical properties of the gel, and further refinements in the material and technique are anticipated to increase ease and efficacy of treatment while minimizing complications.

Abstract
Chronic suppurative otitis media is an inflammatory condition characterized by disruption of tympanic membrane and aural discharge. It is one of the most incidental conditions in head and neck. There has been a substantial debate about the therapeutic approach for some decades now. From review of past medical literature, it was evident that culture and sensitivity is essential in eradicating the causative organism. However, the cost-effectiveness is a major concern for low-income population. Due to such concern, empirical therapy has proved to be a suitable therapeutic approach since commonly found organisms are highly sensitive to routine antibiotics.

Abstract
Chronic ear disease is composed of a spectrum of otologic disorders intrinsically tied to Eustachian tube dysfunction. Presentation can range from asymptomatic findings on physical examination to critically ill patients with intracranial complications. Internists represent the first line in diagnosis of these conditions, making awareness of the common signs and symptoms essential. With surgical management often required, partnership between internal medicine and otolaryngology is fundamental in the management of patients with chronic ear disease.

Abstract
OBJECTIVE To summarize the characteristics of laryngopharyngeal reflux (LPR) in patients with chronic otitis media. METHODS This was a prospective study in which 31 patients with chronic otitis media were enrolled. General patient information, reflux symptom index (RSI), reflux finding scores (RFSs), and Ryan scores were summarized. RESULTS Most (29/31, 93.5%) patients had a negative RSI (RSI ≤ 13). The most common symptoms of these patients were throat clearing (22/31, 71.0%), symptoms of the stomach and esophagus (19/31, 61.3%), and excess throat mucus or postnasal drip (14/31, 45.2%). In contrast to the RSI, most patients (22/31, 71.0%) had a positive RFS (RFS > 7). Among all of the signs found under the transnasal fiber-optic laryngoscope, erythema was the most frequent symptom (31/31, 100.0%), followed by vocal cord edema (27/31, 87.1%), and posterior commissure hypertrophy (27/31, 87.1%). Most cases (24/31, 77.4%) had a positive Ryan score, and most positive scores were upright scores. CONCLUSIONS Most patients with chronic otitis media had LPR simultaneously. The LPR in these patients manifested mainly by a positive RFS under a laryngoscope and not by symptoms of the larynx and pharynx. This suggests that LPR may be an important factor in the pathogenesis of COM and anti-reflux treatment may play a significant role in the management of chronic otitis media.

Abstract
Otitis media (OM) is a common disease affecting humans, especially paediatric populations. OM refers to inflammation of the middle ear and can be broadly classified into two types, acute and chronic. Bacterial infection is one of the most common causes of OM. Despite the introduction of vaccines, the incidence of OM remains significantly high worldwide. In this mini-review article, we discuss the recent treatment modalities for OM, such as suspension gel, transcutaneous immunization, and intranasal and transtympanic drug delivery, including therapies that are currently undergoing clinical trials. We provide an overview of how these recent advancements in therapeutic strategies can facilitate the circumvention of current treatment challenges involving preadolescence soft palate dysfunction, biofilm formation, tympanic membrane (ear drum) barrier and the attainment of efficacious drug concentrations in the middle ear. While traditional first-line immunization strategies are generally not very efficacious against biofilms, new technologies that use transdermal or intranasal drug delivery via chitosan-PsaA nanoparticles have shown promising results in experimental animal models of OM. Sustained drug delivery systems such as penta-block copolymer poloxamer 407-polybutylphosphoester (P407-PBP) or poloxamer 407 (e.g. OTO-201, with the brand name 'OTIPRIO') have demonstrated that treatments can be reduced to a single topical application. The emergence of effective new treatment modalities opens up promising new avenues for the treatment of OM that could lead to improved quality of life for many children and their families.

Abstract
ObjectivesChronic otitis media (COM) is caused by an infection of the middle ear, although it may also be associated with environmental pollutants. Recent reports found that cadmium exposure could be toxic to middle ear cell lines, but the role of cadmium in the development of COM in humans has not been examined to date. We hypothesised that environmental cadmium exposure was associated with an increased risk of COM in the general population.MethodsWe analysed cross-sectional data for 5331 adults of 20 years of age or above, obtained from the Korea National Health and Nutrition Examination Survey 2010–2012. We examined the association between blood cadmium levels and COM diagnosed by an otolaryngologist.ResultsThe highest quartile group of cadmium blood concentration was associated with an OR of 3.33 (95% CI 1.78 to 7.53) for COM, after adjusting for potential confounding factors. Doubling blood cadmium concentration resulted in an OR of 1.58 (95% CI 1.19 to 2.08) for COM. These associations were robust on sensitivity analyses after excluding current smokers and former smokers and after excluding subjects with a potential history of occupational exposure to cadmium.ConclusionsThe results of our study suggest that environmental cadmium exposure is associated with increased risk of COM, and further studies are warranted to understand the pathogenetic mechanism by which COM is caused by cadmium exposure.

Abstract
AbstractObjectives:To review research addressing the polymicrobial aetiology of otitis media in Indigenous Australian children in order to identify research gaps and inform best practice in effective prevention strategies and therapeutic interventions.Methods:Literature review.Results:Studies of aspirated middle-ear fluid represented a minor component of the literature reviewed. Most studies relied upon specimens from middle-ear discharge or the nasopharynx. Culture-based middle-ear discharge studies have found that non-typeableHaemophilus influenzaeandStreptococcus pneumoniaepredominate, withMoraxella catarrhalis, Staphylococcus aureusandStreptococcus pyogenesisolated in a lower proportion of samples.Alloiococcus otitidiswas detected in a number of studies; however, its role in otitis media pathogenesis remains controversial. Nasopharyngeal colonisation is a risk factor for otitis media in Indigenous infants, and bacterial load of otopathogens in the nasopharynx can predict the ear state of Indigenous children.Conclusion:Most studies have used culture-based methods and specimens from middle-ear discharge or the nasopharynx. Findings from these studies are consistent with international literature, but reliance on culture may incorrectly characterise the microbiology of this condition. Advances in genomic technologies are now providing microbiologists with the ability to analyse the entire mixed bacterial communities (‘microbiomes’) of samples obtained from Indigenous children with otitis media.

Abstract
BACKGROUND The goal of this study was to obtain representative Kenyan data on the point prevalence of acute otitis media (AOM) and its sequelae (otitis media with effusion [OME] and chronic suppurative otitis media [CSOM]), a major cause of preventable hearing loss in children in developing countries. In Africa, there are limited studies on the prevalence of AOM and its sequelae in children. METHODS Study subjects were children aged 2 to 15 years and were enrolled from randomly selected preprimary and primary schools. After parental or guardian consent, subjects had a questionnaire administered, otoscopy and tympanometry were done, and audiometry was performed on those with ear problems detected on these examinations. RESULTS A total of 9825 (75%) children was from rural schools. The prevalence of CSOM was 15 of 1000, OME was 15 of 1000, and AOM was 7 of 1000 children. Rural Rift Valley schoolchildren had the highest prevalence of CSOM (24 of 1000) compared with other regions (12 of 1000; P < .0001). Ear discharge occurred before 3.5 years in 50% of 901 children with ear discharge. A history of ear discharge was associated with abnormal tympanograms (odds ratio [OR], 11.9-19.2) and mild-to-severe hearing loss (OR, 21.6-38.6), even in children without ear disease (OR, 10.7-24.4). CONCLUSIONS The burden of AOM sequelae in Kenyan preschool and schoolchildren is significant, and it occurs mostly in the first 4 years of life. By preventing early recurrent AOM, pneumococcal vaccination might partly avert nonreversible sequelae.

Abstract
Otitis media (OM) is a broad term describing a group of infectious and inflammatory disorders of the middle ear. Despite antibiotic therapy, acute OM can progress to chronic suppurative otitis media (CSOM) characterized by ear drum perforation and purulent discharge. Pseudomonas aeruginosa is the most common pathogen associated with CSOM. Although, macrophages play an important role in innate immune responses but their role in the pathogenesis of P. aeruginosa-induced CSOM is not known. The objective of this study is to examine the interaction of P. aeruginosa with primary macrophages. We observed that P. aeruginosa enters and multiplies inside human and mouse primary macrophages. This bacterial entry in macrophages requires both microtubule and actin dependent processes. Transmission electron microscopy demonstrated that P. aeruginosa was present in membrane bound vesicles inside macrophages. Interestingly, deletion of oprF expression in P. aeruginosa abrogates its ability to survive inside macrophages. Our results suggest that otopathogenic P. aeruginosa entry and survival inside macrophages is OprF-dependent. The survival of bacteria inside macrophages will lead to evasion of killing and this lack of pathogen clearance by phagocytes contributes to the persistence of infection in CSOM. Understanding host-pathogen interaction will provide novel avenues to design effective treatment modalities against OM.

Abstract
Chronic Suppurative Otitis Media (CSOM) is a chronic inflammation of middle ear cleft. It presents with discharging ear and decreased hearing. The diagnosis is mostly on clinical examination with otoscope or oto endoscope. Computerised Tomography (CT) of mastoids is done to evaluate the extent of the disease and its complication. High resolution CT is now the investigation of choice for temporal bone disease. This study emphasizes on the importance of CT scan in diagnosis of inflammatory ear diseases and most importantly identifying pitfalls or complications which a surgeon can come across during surgery. The aims and objectives of this study is (1) to establish the efficacy of CT in the diagnosis of the complications and surgical management of chronic inflammatory pathologies of middle ear. (2) To find subgroups of CSOM where CT is particularly useful. In this series, a total of 25 cases presenting to our OPD at Govt. ENT Hospital between 2013 and 2014 have been diagnosed and findings of surgery correlated with HRCT scan of temporal bones done preoperatively. In this study, 64 % of the patients were male and incidence of CSOM with patients undergoing surgery belonged to the age group 21-30 years (32 %). The most common presenting symptom was ear discharge (92 %) and decreased hearing (96 %). The most common type of pathology in this study was attic perforation (36 %) and granulations (40 %) followed by cholesteatoma (36 %) and mucosal edema (16 %). Not all cases presented with complications, facial palsy (12 %) and mastoid abscess (8 %) were among few complications seen. 14 patients (56 %) of 25 cases underwent simple cortical mastoidectomy followed by 9 cases (36 %) for modified radical mastoidectomy and atticotomy for 2 cases (8 %). CT scan findings correlated well with surgical findings for cholesteatoma, middle ear mass and bone erosions. Where as for ossicular integrity and facial canal dehiscence, there was a discrepancy.

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.

Abstract
Conclusion Eustachian tube (ET) dysfunction, which plays a role in the pathogenesis chronic suppurative otitis media (CSOM), does not seem to be due to differences in paratubal structures. Objective The aim of this study was to compare the magnetic resonance imaging (MRI) findings of the paratubal structures of the ET between normal ears and ears in patients with CSOM. Methods The MRI records of 40 patients who underwent tympanomastoidectomy for a diagnosis of CSOM were reviewed retrospectively. The healthy ears served as the control group. The length, diameter, surface area and volume of the tensor veli palatini muscle (TVPM) and levator veli palatini muscle (LVPM) were measured, in addition to the diameter of the pharyngeal orifice of the ET, volume of the Ostmann fat pad, bimucosal thickness of the lumen of the ET, and mucosal thickness. Results In the pathological ears, the mean length of the TVPM and LVPM was 22.6 mm and 19.3 mm, the mean diameter was 3.2 and 5.3 mm, and the mean volume was 1.75 and 3.2 cm(3), respectively. In addition, the mean diameter of the pharyngeal orifice of the ET was 1.9 mm. There were no significant between-group differences in the paratubal structures (p > 0.05).
