Does the Location of a Small Tympanic Membrane Perforation Affect the Degree of Hearing Loss in Adult Patients with Inactive Mucosal Chronic Suppurative Otitis Media?

BACKGROUND: Tympanic membrane perforation due to inactive mucosal chronic suppurative otitis media is a common problem in otolaryngology, with consequent conductive hearing loss. Still, there is controversy about the relationship between the location of the tympanic membrane perforation and the degree of hearing impairment. AIM OF THE STUDY: To assess the correlation between the location of a small tympanic membrane perforation and the degree of conductive hearing loss in adult patients with inactive mucosal chronic suppurative otitis media. PATIENTS AND METHODS: A prospective cross-sectional study enrolled 74 adult patients with small tympanic membrane perforations (perforation involves less than one quadrant of the tympanic membrane) and conductive hearing loss (airbone gap ≥ 20 dB HL) due to inactive mucosal chronic suppurative otitis media for at least 3 months. The locations of the tympanic membrane perforations were classified as anterosuperior, anteroinferior, posterosuperior, and poster inferior perforations. Audiometric analysis and a CT scan of the temporal bone were done for all patients. The means of the air and bone conduction pure tone hearing threshold averages at frequencies 500, 1000, 2000, and 4000 Hz were calculated, and consequently, the air-bone gaps were calculated and presented as means. The ANOVA test was used to compare the means of the air-bone gaps, and the Scheffe test was used to determine if there were statistically significant differences regarding the degree of conductive hearing loss in relation to different locations of the tympanic membrane perforation. RESULTS: The ages of the patients ranged from 20 to 43 years (mean = 31.9 ± 6.5 years), of whom 43 (58%) were females and 31 (42%) were males. The means of the air-bone gaps were 32.29 ± 5.41 dB HL, 31.34 ± 4.12 dB HL, 29.87 ± 3.48 dB HL, and 29.30 ± 4.60 dB HL in the posteroinferior, posterosuperior, anteroinferior, and anterosuperior perforations, respectively. Although the air-bone gap's mean was greater in the posteroinferior perforation, statistical analysis showed that it was insignificant (P-value=0.168). CONCLUSION: In adult patients with inactive chronic suppurative otitis media, the anteroinferior quadrant is the most common location of the tympanic membrane perforation, and there was an insignificant correlation between the location of a small tympanic membrane perforation and the degree of conductive hearing loss.

Association of iron deficiency with chronic suppurative otitis media in adults.

BACKGROUND: Chronic suppurative otitis media (CSOM) is a prevalent chronic inflammatory disease globally. Current research suggests a possible association between anaemia and the development of CSOM. OBJECTIVES: The objective of this trial was to investigate the relationship between iron metabolism and chronic suppurative otitis media (CSOM) in adults aged 20-60 years. MATERIALS AND METHODS: A consecutive sampling case-control study was used. The study participants were divided into a case group (42 children diagnosed with CSOM) and a control group (42 children with normal ears). Haemoglobin (Hb), Hematocrit (Hct), mean corpuscular volume of erythrocytes (MCV), serum iron level (SI), unsaturated iron-binding capacity (UIBC), total iron-binding capacity (TIBC), transferrin (TF), ferritin (Fer) were tested in all the participants, and the results were compared with the normal ranges of the World Health Organization (WHO). The comparative analysis of cases and controls was performed using the Fisher extract test, independence t-test, or Mann-Whitney U test. p-value <.05 was considered statistically significant for correlation. RESULTS: There were 61 patients with CSOM and 61 controls included in the study. In the case group, 16 out of 61 patients (26.2%) had low ferritin levels and in the control group, 1 out of 61 patients (1.6%) had low ferritin levels (p < .001). In the case group, 6 (9.8%) of 61 patients had IDA, and in the control group, there were no patients with IDA among 61 patients (p = .027). There were significant differences in SI, UIBC, and Fer parameters between the groups. CONCLUSIONS: In adult patients, the incidence of iron deficiency was higher in CSOM patients than in controls. Iron deficiency may be considered a potential risk factor for chronic suppurative otitis media, and serum iron parameters should be evaluated in these CSOM patients and further studies should be conducted to better understand the potential link between iron deficiency and CSOM.

Risk factors associated with the development of chronic suppurative otitis media in children: Systematic review and meta-analysis.

OBJECTIVES: Chronic suppurative otitis media (CSOM) is defined as persistent discharge through a tympanic membrane perforation for greater than 2 weeks. It is associated with a significant disease burden, including hearing loss, and reducing its incidence could significantly improve short- and long-term health. We aimed to identify risk factors associated with the development of CSOM in children. DESIGN AND SETTING: Systematic review and meta-analysis of studies set in community, primary and secondary care settings, identified from Medline, Embase and Cochrane databases from 2000 to 2022. PARTICIPANTS: Children 16 years old and below. MAIN OUTCOME MEASURES: Clinical diagnosis of CSOM. RESULTS: In total, 739 papers were screened, with 12 deemed eligible for inclusion in the systematic review, of which, 10 were included in the meta-analysis. Risk factors examined included perinatal, patient, dietary, environmental and parental factors. Meta-analysis results indicate that atopy (RR = 1.18, 95% CI [1.01-1.37], p = .04, 2 studies); and birth weight <2500 g (RR = 1.79 [1.27-2.50], p < .01, 2 studies) are associated with an increased risk of CSOM development. Factors not associated were male sex (RR = 0.96 [0.82-1.13], p = .62, 8 studies); exposure to passive smoking (RR = 1.27 [0.81-2.01], p = .30, 3 studies); and parental history of otitis media (RR = 1.14 [0.59-2.20], p = .69, 2 studies). CONCLUSION: Optimal management of risk factors associated with CSOM development will help reduce the burden of disease and prevent disease progression or recurrence. The current quality of evidence in the literature is variable and heterogeneous. Future studies should aim to use standardised classification systems to define risk factors to allow meta-analysis.

Tympanomastoidectomy versus parenteral antibiotic therapy for pediatric otorrhea.

OBJECTIVE: To evaluate the efficacy of tympanomastoidectomy versus parenteral antibiotic therapy for otorrhea as a result of chronic suppurative otitis media (CSOM) without cholesteatoma in the pediatric population. METHODS: A retrospective review of 221 patients treated for otorrhea at a tertiary academic pediatric hospital was performed to evaluate the impact of tympanomastoidectomy versus parenteral antibiotic therapy on resolution of otorrhea. Inclusion criteria were age 0-18 years, prior treatment with otic and/or oral antibiotic, prior history of tympanostomy tube placement for recurrent otitis media, history of otorrhea, treatment with tympanomastoidectomy or parenteral antibiotic therapy, and follow-up of at least 1 month after intervention. Time to resolution was compared between the two modalities adjusting for age, bilateral ear disease status, and comorbidities using a Cox proportional hazard model. RESULTS: Eighty-three ears from 58 children met the inclusion criteria. Ears that initially underwent tympanomastoidectomy had a significantly shorter time to resolution of symptoms (median time to resolution) 9 months (95 % confidence interval CI: 6.2-14.8) vs. 48.5 months (95 % lower CI 9.4, p = 0.006). On multivariate analysis, however, only bilateral ear disease status was independently associated with time to resolution of symptoms (hazard ratio 0.4, 95 % CI 0.2-0.9, p = 0.03). There was no statistically significant difference in the rate of treatment-related complications when comparing tympanomastoidectomy to parenteral antibiotic therapy (p = 0.37). CONCLUSION: When adjusting for age, bilateral ear disease status, and comorbidities, there does not appear to be a significant difference in time to resolution of symptoms when comparing parenteral antibiotic therapy to tympanomastoidectomy. An informed discussion regarding risks and benefits of each approach should be employed when deciding on the next step in management for patients with CSOM who have failed more conservative therapies.

[Acute purulent otitis media in children]. / Ostryi gnoinyi srednii otit u detei.

OBJECTIVE: Improving the effectiveness of inpatient care for children with acute purulent otitis media. MATERIAL AND METHODS: 100 children at the age from 0 to 18 years were inspected from January to August 2021. The main diagnostic methods included otoscopy, pharyngoscopy, rhinoscopy. Bacteriological examination of the pus from the ear was done for all patients. RESULTS: Acute purulent otitis media is a common cause of hospitalization in children aged 0 to 3 years. The main causative agents of the disease in toddlers are Staphylococcus aureus and pneumococcus (38%), in preschoolers and primary school children - pyogenic streptococcus and pneumococcus (30%), in high school students - Staphylococcus aureus.

Polymicrobial Bacterial Meningitis in a Patient with Chronic Suppurative Otitis Media: Case Report and Literature Review.

Polymicrobial meningitis is a rare entity in the adult population, especially in the antibiotic era. However, disorders such as chronic suppurative otitis media (CSOM) or even poor oral hygiene are considered risk factors for the development of such cerebral infection. We report a case of polymicrobial meningitis associated with oto-mastoiditis in a 64-year-old female patient known to have CSOM. The patient presented atypical symptoms for community-acquired meningitis, showing subacute evolution of headache, without fever or neck stiffness. The aerobe microorganisms Streptococcus anginosus and Corynebacterium spp., sensitive to beta-lactamines, and the anaerobe Prevotella spp., resistant to penicillin and metronidazole, were isolated from CSF specimens, while Proteus mirabilis and Enterococcus faecalis were identified from the ear drainage. The diversity of pathogens identified in our case led us to the hypothesis of two different sources of meningitis: otogenic and/or odontogenic. Favorable evolution was obtained after a multi-disciplinary approach, combining surgery and broad-spectrum antibiotics. In addition, we performed a literature review that highlights the low incidence of polymicrobial mixed aerobe-anaerobe meningitis.

Pertinence of Streptococcus anginosus group in intracerebral abscesses in the era of extended antibiotic resistance.

AIMS: • To study the incidence of Streptococcus anginosus group (SAG) in pyogenic or community acquired intra cerebral abscess. • To understand the risk factors for the same. • To analyze the specific radiological features and clinical outcome after surgery and antibiotic therapy. METHODS: This is a retrospective observational study of case series over a period of one year. Patients diagnosed with intracerebral abscess were included in the study. Pus collected from were received in the laboratory and processed according to the standard protocols. Data regarding the clinical findings and demographics were collected from medical records. FINDINGS: A total of 202 samples were studied. 103 were found to be pyogenic. SAG were isolated from 21 samples (20.38%) and all the isolates were sensitive to Penicillin. Age of the patients ranged from 18months to 68years. Male preponderance was noted with male to female ratio of 4:1. Otogenic infections were the most common predisposing factors and focus of infection could not be ascertained in 5 patients. All patients were treated with surgical intervention and antibiotics (Vancomycin, Amikacin and Metronidazole) for 6 weeks and recovery was remarkable. One patient succumbed to the illness. CONCLUSION: SAG can be an aggressive pathogen with propensity for abscess formation. Chronic Suppurative Otitis Media (CSOM) is still a major cause of intracerebral abscess in developing country like India which is a benign and curable disease and should not be neglected. Injudicious use of antibiotics and negligence regarding the dose and duration of therapy from both patients and health care providers is the major cause for common infections to become more difficult to treat and succumbing to complications.

Cerebellar Abscess Induced by Cochlear Fistula due to Chronic Suppurative Otitis Media.

Cochlear fistulas with cholesteatoma as the primary disease have been reported frequently in the relevant literature. However, there are no reports of cochlear fistula without cholesteatoma due to chronic suppurative otitis media with intracranial complications. We report a case of cochlear fistula due to chronic otitis media that was diagnosed after the onset of a cerebellar abscess. The patient was a 25-year-old man with severe autism. He was admitted to our hospital with otorrhea from his left ear, emesis, and impaired consciousness. Computed tomography (CT) of the head showed left suppurative otitis media, left cerebellar abscess, and brainstem compression due to hydrocephalus. Right extra-ventricular drainage and brain abscess drainage were urgently performed. The next day, foramen magnum decompression and abscess drainage with partial resection of the swollen cerebellum were performed for decompression purposes. He was subsequently treated with antimicrobial therapy, but magnetic resonance imaging of the head showed an increase in the size of the cerebellar abscess. Re-examination of the temporal bone CT scans revealed a bony defect in the left cochlear promontory angle. We assumed that the cochlear fistula was responsible for the otogenic brain abscess. Thus, the patient underwent surgical closure of the cochlear fistula. After the operation, the cerebellar abscess lesion gradually shrank, and his general condition stabilized. Cochlear fistula should be considered in the management of patients with inflammatory middle ear disease associated with otogenic intracranial complications in the middle ear.

[Partial sequestration of the labyrinth in a child with chronic suppurative otitis media with cholesteatoma]. / Chastichnaya sekvestratsiya labirinta u rebenka s khronicheskim gnoinym srednim otitom s kholesteatomoi.

A clinical case of a 16-year-old child with chronic suppurative otitis media with cholesteatoma complicated by partial labyrinth sequestration is presented. The case describes is a rare disorder. Computed tomography of temporal bones consistent with intraoperative data was decisive in establishing the diagnosis and the surgery extent.

[Choristoma of the middle ear]. / Khoristoma srednego ukha i sostsevidnogo otrostka.

Choristoma is one of the varieties of congenital developmental anomalies, where one or another normal tissue of the body is located in an atypical place for itself. The short literary review of choristoma of middle ear is presented in article. A rare clinical cases of salivary gland choristoma of the middle ear (5-year-old girl with left-sided conductive hearing loss of III degree) and glial choristoma of the mastoid (19-year-old man with signs of chronic suppurative otitis media of the right ear) are described.

Impact of Otorrhea and Positive Cultures on Tympanoplasty Outcomes.

BACKGROUND: Chronic suppurative otitis media is a long-standing middle ear infection with a perforated tympanic membrane. Tympanoplasty is the mainstay of treatment. Most surgeons prefer to operate on dry ears; however, this may be difficult to achieve. OBJECTIVES: To investigate the effect of otorrhea and positive cultures on the outcome of tympanoplasty. METHODS: This retrospective analysis reviewed patients with chronic suppurative otitis media who underwent tympanoplasty 2008-2015. Patients were divided into three groups: active discharge and bacterial growth, active discharge without bacterial growth, and no ear discharge. Surgical outcomes were compared among the groups. RESULTS: Among 101 patients included, 43 ears (42.6%) had discharge preoperatively, 58 (57.4%) were dry. Overall closure rate was 81.2% (82/101). Preoperative active discharge closure rate was 88.3% (38/43) and without discharge 75.9% (44/58). There were 38 positive cultures preoperatively and five negative cultures. Cultures were not obtained in 58 cases. Success rates were 89.5%, 80%, and 75.9%, respectively. No significant difference was found between patients who had positive or negative cultures before the procedure (P > 0.48) or among the three groups (P = 0.25). The most common bacteria were Pseudomonas aeruginosa (n=17), followed by Staphylococcus species (n=10). None was significantly associated with operative failure (P = 0.557). The postoperative air threshold difference was not affected by culture results (P = 0.3). CONCLUSIONS: Tympanoplasty success rates and postoperative air threshold differences were not affected by the presence of preoperative otorrhea or positive ear cultures. Surgery can be performed even when the ear is not dry.

Diplopia in a Child: Gradenigo Syndrome Is an Unforgettable Disease.

Gradenigo syndrome is a clinical triad of abducens nerve palsy, retro-orbital pain (trigeminal ganglionitis), and chronic otorrhea (otitis media). The etiology of Gradenigo syndrome results from apical petrositis secondary to suppurative otitis media. Although apical petrositis has gradually become uncommon in modern society due to the widespread use of antibiotics, Gradenigo syndrome should be considered in the differential diagnosis of a child's diplopia.

Comparison of Endoscopic Cartilage Myringoplasty in Dry and Wet Ears With Chronic Suppurative Otitis Media.

OBJECTIVES: This study compared the rate of graft success, as well as hearing improvement and dry ear time between dry ears and wet ears with otomycosis or without otomycosis in patients with chronic suppurative otitis media (CSOM) after endoscopic cartilage myringoplasty. METHODS: This retrospective study was conducted in a tertiary hospital in Shanghai. In total, 83 patients with CSOM (43 with dry ears and 40 with wet ears) were included. Among the 40 patients with CSOM and wet ears, 25 exhibited otomycosis. All patients underwent endoscopic myringoplasty, and perforations were repaired using tragal cartilage with a single-sided perichondrium. Patients were followed up for at least 6 months. Pure-tone hearing was examined preoperatively and at 3 months postoperatively. The graft uptake rate, hearing improvement, and dry ear time were compared between the groups. RESULTS: The graft success rate did not differ significantly between the dry-ear and wet-ear groups (95.35% and 90.00%, respectively). Furthermore, the graft success rate also did not differ significantly between patients with wet ears and otomycosis and those with wet ears without otomycosis (92.00% and 86.67%, respectively). Hearing gain did not differ significantly between the dry-ear and wet-ear groups. No significant difference in hearing gain was also found in patients with wet ears with or without otomycosis. However, the time to dry ear was significantly longer in the wet-ear group than in the dry-ear group. CONCLUSION: Patients with CSOM and wet ears required more time to achieve a completely healthy status. However, the graft success rate and hearing improvement were not affected by a wet middle ear and otomycosis. Thus, endoscopic myringoplasty using tragus cartilage is an effective treatment for refractory CSOM in patients with wet ears and otomycosis.

Analysis of tinnitus severity and associated factors in patients with chronic otitis media in a low- to middle-income country.

OBJECTIVE: This study aimed to describe the tinnitus severity in patients with chronic otitis media (COM) and describe the sociodemographic and clinical variables associated with tinnitus severity. DESIGN: Cross-sectional study. Two otology-referral centers in Bogotá (Colombia) were included. Sociodemographic, clinical associated factors and quality of life questionnaires were applied. Otoscopic evaluation and audiometric data were collected. STUDY SAMPLE: About 231 adults with COM. RESULTS: Up to 51.5% of the patients reported severe tinnitus discomfort, 21.7% moderate discomfort, and 26.8% minor discomfort. Factor associated with increased tinnitus severity in patients with COM were older age (aOR: 1.02; 95% CI: 1.01-1.05), higher education (aOR: 2.24; 95% CI: 1.03-4.87), ear discharge during childhood (aOR: 1.88; 95% CI: 1.02-3.45), cholesteatoma in one ear (aOR: 2.26; 95% CI: 1.05-4.88), and pure-tone air average over 15 dB (aOR: 2.08; 95% CI: 1.28-3.36). Differences of 10-points in symptoms severity and 15-points in the total score of the "Chronic Suppurative Otitis Media Questionnaire-12" were found between the tinnitus severity groups. CONCLUSIONS: Our results highlight the need for further research on the associated factors of tinnitus severity on COM patients. COM patients with higher tinnitus severity presented worse audiometric results and worse quality of life outcomes.

Evaluation of postural stability and vestibulo-ocular reflex in adults with chronic suppurative otitis media.

PURPOSE: To evaluate the vestibulospinal reflex and vestibulo-ocular reflex (VOR) in patients with chronic suppurative otitis media (CSOM) using posturography and the video head impulse test (vHIT). METHODS: Sixty-five patients with CSOM and 65 healthy participants as controls were included. Patients with CSOM were instructed to complete the dizziness handicap inventory (DHI). All participants underwent otoscopy, pure-tone audiometry, posturography sensory organization test (SOT), and vHIT. RESULTS: Patients with CSOM exhibited a high prevalence of dizziness. The CSOM group had poor SOT vestibular scores compared to the control group. Patients with CSOM had worse sways in the antero-posterior and mediolateral planes. The CSOM group was divided into two subgroups according to the type of hearing loss. SOT vestibular scores were significantly poorer in the mixed hearing loss group than those in the conductive hearing loss group. We found a positive correlation between disease duration and poor SOT vestibular scores. Moreover, poor SOT vestibular scores correlated with high DHI scores. We found abnormalities in the vHIT results in the CSOM group in the form of low VOR gain and corrective saccades. CONCLUSION: Our study provides clinical evidence of dizziness, poor postural control, and VOR abnormalities in patients with CSOM. The presence of sensory elements of hearing loss in patients with CSOM appears to be positively associated with vestibular dysfunction.

Correlation of Eustachian tube function with the results of type 1 tympanoplasty: a prospective study.

OBJECTIVES: This study aims to evaluate Eustachian tube (ET) function tests and their impact on outcomes of tympanoplasty in patients with inactive chronic suppurative otitis media. MATERIALS AND METHODS: A prospective study was conducted involving patients diagnosed with chronic suppurative otitis media (CSOM) and having a central dry perforation. Assessment of the ET function was done for all included cases by three tests; pressure swallow equalization test, saccharine test and methylene blue test. The primary outcome is the graft success rate defined as intact graft without any residual perforation at 6 months postoperatively. Secondary outcomes include hearing assessment and possible associated complications. RESULTS: 64 patients were included in the study with an average age of 36.59 ± 11.96 years. All patients underwent assessment of the ET function by saccharine test, methylene blue test and pressure equalization test (PET) followed by microscopic post-auricular tympanoplasty. Successful tympanoplasty is achieved in 93.75% of cases with residual perforation in four patients. Mean air-bone gap is significantly improved from 23.73 ± 2.80 preoperatively to 10.93 ± 5.46 postoperatively. Results of Methylene blue test has no statistical impact on graft take rate (p value = 0.379), while saccharine test and pressure equalization test results have statistically significant correlation with graft success (p value ≤ 0.001). CONCLUSIONS: Saccharine and Pressure equalization tests have a good positive correlation with the graft healing in tympanoplasty, while methylene blue test was found to have no correlation with the success rate.

Mastoid obliteration with hydroxyapatite vs. bone pâté in mastoidectomy surgery performed on patients with cholesteatoma and chronic suppurative otitis media: a retrospective analysis.

PURPOSE: To compare the efficacy and safety of hydroxyapatite vs. bone pâté as obliteration material in mastoidectomy surgery for patients with chronic suppurative otitis media and cholesteatoma. METHODS: This is a retrospective, multi-center, cohort study. All patients were followed up with micro-otoscopy, audiometry, and, if indicated, MRI with diffusion-weighted imaging. The following outcome parameters were analyzed: procedure safety (wound infections and complications), cholesteatoma recidivism rates (residual/recurrent), control of infection (Merchant's scale), and hearing results (pure-tone averages at 500/1000/2000/4000 Hz). RESULTS: Eighty-three cases were included: 45 obliterated with hydroxyapatite and 38 with bone pâté, with a mean follow-up time of, respectively, 25 and 24 months. Wound infections were only detected in the bone pâté group (4.8%) and successfully treated with oral or intravenous antibiotics and surgical drainage (p = 0.026). No other major surgical complications were observed in both groups. Cholesteatoma recidivism was observed in 15% using hydroxyapatite and 12% using bone pâté (p = 0.471). Complete control of infection (Merchant 0) was achieved in 76.2% using bone pâté and 86.8% using hydroxyapatite at 12 months postoperatively (p = 0.223). All patients showed good postoperative healing without complete failure to manage infection (Merchant 3). Pre- and postoperative audiometry showed significant improvement in hearing results in both groups. No significant difference between the obliteration materials was observed. CONCLUSIONS: Evaluation of mastoid obliteration reveals that hydroxyapatite and bone pâté are safe and effective obliteration materials, with high success rates in achieving a dry ear, low recidivism rates, and good hearing outcome, respecting the short-term limitation. In addition, our study shows that hydroxyapatite results in fewer postoperative wound infections compared to bone pâté.

Chronic suppurative otitis media and immunocompromised status in paediatric patients.

INTRODUCTION: The role of immunodeficiency in the development of chronic suppurative otitis media (CSOM), especially in paediatric populations, have yet to be fully elucidated. The purposesof this study is to investigate the association between immunocompromised status and CSOM among paediatric population in a tertiary hospital in Indonesia. MATERIALS AND METHODS: A cross-sectional study was performed by retrieving medical records of paediatric patients, with and without CSOM (age 0-18 years), visiting otorhinolaryngology (ENT-HNS) outpatient clinic in a tertiary hospital in Indonesia (2018-2020). We collected data on comorbidities causing immunosuppression such as HIV status, tuberculosis, and cancer. RESULTS: Among the 1018 included patients (50 immunocompromised children), HIV infection was the most common cause of immunodeficiency in the CSOM group (24 patients, 60%), and cancer in the non-CSOM group (10 patients, 100%). We found a significant association between immunocompromised hosts and CSOM (odds ratio 19.5 [95% confidence interval: 9.5-39.9], p<0.001). CONCLUSION: Immunocompromised children with HIV, tuberculosis, or cancer may be more vulnerable to CSOM. Further research is required to explore the association between other immunocompromised conditions and CSOM in paediatric populations.
