Latency Shift

<p class="abstract"><strong>Background:</strong> Chronic suppurative otitis media (CSOM) emerging as common hearing problems in the recent years with high prevalence requiring immediate attention. Hence, our study includes assessment of adult patients with CSOM using electrophysiological test, auditory brainstem response (ABR) and analysing the latency of ABR peaks in order to find the effect of CSOM on ABR latency with respect to shift in latency.</p><p class="abstract"><strong>Methods:</strong> The study followed cross sectional study design where data collected from March to September 2019 were used. A total of 50 subjects with unilateral CSOM were analysed. Descriptive statistics and paired t-test was used for statistical analysis of the data.  </p><p class="abstract"><strong>Results:</strong> The data was divided into 3 groups based on degree of hearing loss (mild, moderate and moderately severe). The Mean ABR peak latency was analysed and subjects showed a significant latency shift. Also, it was found that the magnitude of latency shift increased with increase in degree of hearing loss.</p><p class="abstract"><strong>Conclusions:</strong> Hence the study concludes that as the amount of conductive component increases the pure tone threshold deteriorates and ABR latency gets affected. Also, the morphology of ABR peaks on comparison to the normal hearing ear gets affected due to constant conductive pathology in the pathological ear.</p><p class="abstract"> </p>

Suppurative Otitis Media

Background: To know the prevalence of sensorineural hearing loss among chronic suppurative otitis media patients To study the correlation between duration and clinical findings of CSOM with the degree of hearing loss. Materials and Methods Hospital based cross sectional study of patients aged between 10 to 45years with unilateral chronic suppurative otitis media attending Tirumala Super speciality Hospital, Kadapa from December 2015 to November 2017 with sample size of 100 cases were taken. Results: Out of the 100 cases, 10 patients were having sensorineural hearing loss. Thus the percentage is 10%. Out of the 10 cases of sensorineural hearing loss, no cases with sensorineural hearing loss between 10-15yr and 16-20yr age group. 2 were between in the age group of 26-30yr, 31-35yr and 36-40yr age group and 4 patients were in the age group of 41-45yr. Out of 100 patients 52 were males and 48 were females. Out of 10 patients with sensorineural hearing loss 6 were males and 4 were females. The duration of ear discharge ranged from 3 months to more than 15 years. Among the 100 patients studied 64 had ear discharge from 3months to 5yr. 16 had ear discharge from 6-10yr, 11 had ear discharge from 11-15yr and 9 had ear discharge of more than 15years. Conclusion: Our study shows presence of significant (10%) sensorineural hearing loss in patients with chronic suppurative otitis media. Duration of ear discharge correlates well with sensorineural hearing loss. No significant correlation between sex and sensorineural hearing loss. Keywords: Chronic suppurative otitis media, tubotympanic disease, sensorineural hearing loss.

Suppurative Otitis Media

AbstractObjectiveChronic suppurative otitis media is a major cause of disabling childhood hearing loss, especially in low-income countries. Estimates on its prevalence in sub-Saharan Africa range from the lowest to the highest in the world (less than one per cent to more than five per cent). However, the prevalence of chronic suppurative otitis media in Zimbabwe is largely unknown. This study aimed to determine the prevalence of paediatric chronic suppurative otitis media and other middle-ear pathology in rural Zimbabwe.MethodA cross-sectional study was performed in primary school children aged 4–13 years from the rural province of Mashonaland East. Participants underwent video otoscopy and tympanometry.ResultsOut of 451 examined children, two (0.4 per cent) had chronic suppurative otitis media. Acute otitis media was present in one (0.2 per cent), otitis media with effusion was present in five (1.1 per cent) and scarring was present in 69 (15.3 per cent).ConclusionChronic suppurative otitis media and otitis media sequelae were surprisingly uncommon in this sample of rural primary school children in Zimbabwe. More studies, preferably population-based, are needed to enable more precise estimates of chronic suppurative otitis media prevalence in Zimbabwe.

<p class="abstract"><strong>Background:</strong> Chronic suppurative otitis media (CSOM) is typically a persistent disease insidious in ONSET, affecting the mucoperiosteal lining of middle ear cleft, often capable of causing severe destruction and irreversible sequelae and manifests clinically with hearing impairment and discharge. Successful management of unsafe CSOM has posed challenge before otolaryngologists for ages.</p><p class="abstract"><strong>Methods:</strong> The prospective study is based on 40 patients of unsafe CSOM who were managed and followed up in the post graduate department of otorhinolaryngology and head and neck surgery of Government medical college Srinagar with relevant data was recorded on the proforma.  </p><p class="abstract"><strong>Results:</strong> All the patients who underwent single stage tympanomastoid surgery with or without ossicular chain reconstruction had no evidence of recurrent disease at follow up with 82.5% were below the age of 40, of which 40% were between 21 to 30 years. Males were more involved than females (1.2:1), also CT scan findings were co related with intra operative findings during our study.</p><p class="abstract"><strong>Conclusions:</strong> In conclusion a perfectly performed canal wall down mastoidectomy with tympanoplasty with us without ossiculoplasty in same sitting give good and acceptable post-operative results as far as the hearing improvement and dry and safe ear is concerned.</p>

Suppurative Otitis Media

Background: Permanent perforation in the eardrum with persistent drainage from middle ear for more than six weeks is labelled as chronic suppurative otitis media. The major disability of long standing chronic suppurative otitis media presents as disability in hearing thresholds both in young children and adults. The disease has a fewer prevalence in urban regions and mostly is found in the rural population. Aim: To identifying the Prevalence of hearing loss which is sensorineural in patients having middle ear chronic infection (CSOM). Study design & setting: Cross-sectional survey conducted in the department of ENT, Jinnah Hospital Duration/date of the study: 01st February 2020 to 31STJuly 2020 Methods: A Total number of 180 patients were included as a sample in the study. Keeping the level of confidence to 95% and keeping the margin of error to minimum to 5%. These statistics were generated keeping the frequency level of hearing in these patients to minial of 16%. The sampling technique would be non probability type of sampling with a purpose. Results: The results of the study concluded that patients of both sex ranged between first decade and fifth decade. A total of 180 patients had 114 male gender and 66 female gender patients. Patients having chronic middle ear disease were segregated into CSOM (tubo tympanic) with 137 patients and CSOM (attico antral) with 43 patients. The primary indicator of hearing loss in these patients however showed 23 patients having a hearing loss of sensori neural type and 157 patients did not have any sensori neural hearing loss. Conclusions: This research study draws a conclusion that majority cases of chronic middle ear infection is usually the safe type (Tubo tympanic) while a very fewer of these patients of CSOM would have (Attico antral) or dangerous type of CSOM. The major variable of the research, in the form of hearing loss which was sensori neural in patients presenting with CSOM was (12.8%). This percentage is much lower when compared with conductive hearing loss in CSOM. Keywords: Otitis media of chronic type with suppuration, pure tone audiometry, sensory neural hearing loss
