Of the organisms isolated Stap aureus (53%) was most common followed by <em>Pseudomonas</em> (36%). All the gram-positive organisms were sensitive to cotimaxozole, amikacin and gentamycin and all gram-negative organisms were sensitive to ciprofloxacin, amikacin and netlimycin. </p><p><strong>Conclusions: </strong>It is better to collect an ear swab in all CSOM cases and then start antibiotics based upon the culture and sensitivity reports in order to improve the results and reduce the emergence of resistant strains, which can happen when antibiotics are prescribed randomly.</p>

Local and systemic oxidative stress in chronic suppurative otitis media

Introduction. According to the literature, oxidative stress is described as one of the main factors in the pathogenesis of chronic suppurative otitis media, supporting the inflammatory process at the local level. The transition of inflammatory mediators to the systemic level is associated with the risk of developing ear purulent-destructive complications. The study of the products of lipid peroxidation in comparison with morphological changes in the structures of the temporal bone will justify the tactics of the operation.Aim. Comparison of the levels of lipid peroxidation products at the local and systemic levels in chronic suppurative otitis media, depending on the nature of pathomorphological changes in the structures of the temporal bone.Materials and methods. A prospective study of 130 patients with chronic suppurative otitis media at the age of 20-62 years with a verified diagnosis of chronic suppurative otitis media, admitted for surgical treatment, was carried out. To study the indicators of oxidative stress at the systemic level, the blood serum of patients was used; at the local level, the bone biomaterial obtained from patients during the surgical treatment of chronic suppurative otitis media was used. The quantitative determination of the primary, secondary and final products of peroxidation was carried out in the groups of patients with separate registration of lipoperoxides in the heptane and isopropanol phases of the lipid extract by spectrophotometry.Results and discussion. In the observation of patients with morphological signs of purulent destruction of the temporal bone, not only a local level of inflammation activity, but also a systemic level of an unfavorable outcome was revealed in two variants: osteoproliferation or osteonecrosis of the bone tissue of the temporal bone in chronic purulent otitis media with a constant threat to the patient's life due to intracranial purulent complications.Conclusion. The appearance in low concentrations of lipid peroxidation products in serum in patients with chronic purulent otitis media substantiates the need for a behind-the-ear approach in reconstructive-sanitizing otosurgery even with minimal clinical manifestations and CT scan data, since at the preclinical level it confirms the osteonecrotic type of bone remodeling with the risk of delayed death.

Efficacy of Acetic Acid Irrigation in Management of Chronic Suppurative Otitis Media “A Prospective Study

Background: Prior to surgical management of chronic suppurative otitis media (CSOM) for the dry ear medical management is necessary. CSOM is a biofilm disease and due to this has antibiotic resistance. The pillar of its treatment included aural cleaning according to standard protocols, application of topical germ free antiseptic and use of antimicrobials. Acetic acid due to its ability in reducing the pH may be effective in reducing the growth of microorganisms. Objective: The aim of the study was to compare the efficacy of irrigation with acetic acid versus systemic antibiotics in CSOM patients. Materials & Methods: A total of 134 patients, who came to the ENT department of Sheikh Zayed Hospital, Lahore between 1st April 2020 to 30th September 2020, who had CSOM, of age 15 to 55 years and both genders were included in the study. The patients were divided randomly into two groups. Group A patients received aural toilets and irrigation with acetic acid and Group B received 500 mg of ciprofloxacin twice a day for 2 weeks. Results: The mean age (in years) of the patients in Group A was 37.45±7.32 and in Group B, it was 37.96±7.57. The efficacy of irrigation with acetic acid versus systemic antibiotics was 89.55% and 68.66% respectively and this difference between the two groups was found to be statistically significant (p=0.003). Conclusion: Irrigation with acetic acid was better than systemic antibiotics in managing patients with CSOM. Key words: Acetic acid, CSOM, Middle ear

Long-Term Health Utilization and Outcomes in Chronic Suppurative Otitis Media

Objective To report health utilization patterns and outcomes of medical and surgical management in patients with chronic suppurative otitis media (CSOM). Study Design Retrospective cohort. Setting Academic otology clinic. Methods This study included 175 patients with CSOM with a first clinic visit at our institution between March 2011 and November 2016. All patients displayed a diagnosis of CSOM by International Classification of Diseases code, had at least 1 episode of active CSOM (defined as perforation with otorrhea), and had a documented history of chronic ear infections. The mean age was 49.5 ± 1.5 years, 53% were female, and mean follow-up time was 3.5 ± 0.3 years. Results Patients had an average of 9.5 ± 0.5 otology visits, 4.7 ± 0.4 prescriptions, and 1.7 ± 0.1 surgeries, with estimated per patient cost ranging from $3927 to $20,776. Under medical management, 69% of patients displayed recurrence of disease, with a median time to recurrence of 4 months. For tympanoplasty and tympanomastoidectomy, median time to recurrence was similar at 5 and 7 years, respectively ( P = .73). At the most recent visit, the prevalence of all patients with CSOM displaying moderate or worse sensorineural hearing loss (SNHL) was 41%. Conclusions CSOM represents a major public health issue with high health care utilization and associated costs. Surgery is superior to medical therapy for achieving short- to medium-term inactive disease. Patients with CSOM display a high SNHL burden.

Correlation between Intraoperative Ossicular Status and Conductive Hearing Loss Degree among Chronic Suppurative Otitis Media Patients in Dr Mohammad Hoesin General Hospital Palembang

Background: Chronic suppurative otitis media (CSOM) is a chronic inflammation of the mucosa and periosteum of the middle ear and mastoid cavity that defined as a perforated tympanic membrane with persistent drainage for more than 2 months. Preoperative hearing threshold and air bone gap (ABG) assessment are expected to predict the ossicular status which can only be ascertained intraoperatively. This study aimed to determine the correlation between intra-operative ossicular status and the degree of conductive hearing loss assessed based on the hearing threshold and average ABG among CSOM patients in RSUP Dr. Mohammad Hoesin Palembang. Methods: Observational research using a cross sectional design. The data were collected using medical record on 64 subjects with a diagnosis of CSOM who underwent mastoidectomy surgery at Dr. Mohammad Hoesin Hospital Palembang for the period of March 2019 to June 2021. Results: From 64 samples conducted in the study, the average ossicular status score in CSOM patients was 1.84 ± 1.48, with the highest group scoring 0 being the malleus incus and intact stapes as many as 21 patients (31.3%). There was a strong positive correlation between hearing threshold scores and intra-operative ossicular status scores (p<0.005, R=0.5) and there was a strong positive correlation between ABG scores and intra-operative ossicular status scores (p <0.005, R=0.6). From the linear regression test, the most influential in predicting intra-operative ossicular status scores were gender, hearing threshold value, ABG value, and the presence of cholesteatoma Conclusions: There is a significant relationship between intra-operative ossicular status and the degree of conductive hearing loss in CSOM patients.

Microorganisms and Culture and Sensitivity Pattern in Chronic Suppurative Otitis Media in a Tertiary Care Hospital

Introduction CSOM is defined as persistent or intermittent infected discharge of more than three months duration through the perforated or non intact tympanic membrane caused by bacteria, fungi and virus resulting in inflammation of mucosal lining that often results in partial or total loss of tympanic membrane and ossicles. The aim of study was to study the current bacteriological profile responsible for the disease. Methods This descriptive cross sectional study was carried out at the department of Ear , Nose and Throat (ENT) and Head and Neck Surgery (HNS) in a tertiary care centre from January 2019 to December 2020. Ethical approval was taken from Institutional Review Committee (Reference number 52/2021). A convenient sampling method was used and data analysis was done in Microsoft Excel . Point estimate at 95% confidence interval was calculated along with frequency and proportion for binary data. Results There were a total of 324 patients included in the study. The age range was from five to sixty-eight years. Most patients were of the age group below 10 years. There were a total of 178 males and 146 females. The most common organism isolated were Staphylococcus aureus 145 (44.8%) and Psedomonas aeruginosa 86 (26.6%). Conclusions Staphylococcus aureus and Pseudomonas aeruginosa were the most common organisms responsible for chronic suppurative otitis media in our study.
