“…Nearly similar rates of normal middle ear mucosa were reported in the studies. [18,19] The present study corroborated the fact that middle ear pathology reflects the antral pathology, as similar observation was reported in the study by Veeranjaneyulu P et al [18] The pattern of ossicular necrosis has been similar with long process of incus was the commonest ossicles to be eroded followed by stapes superstructure, as also reported by Rout MR et al [20] In our study granulation tissue was associated with ossicular erosion in most of the cases, which has been supported in literature. [19,20] Complications encountered in the present study were mostly associated with squamous disease with prolonged untreated, partially treated & neglected disease.…”

Background: Chronic otitis media (COM) is the commonest disorder in Otorhinolaryngology practice, characterized by chronic inflammation of the middle ear cleft and mastoid cavity which presents with recurrent ear discharge and deafness. It results in considerable morbidity and may even cause extra-cranial and intra-cranial complications. Infections of the middle ear and complications caused by COM, are still a major public health problem in the developing countries like India. It is one of the main causes for preventable hearing loss when treated appropriately. It is important to review the changing trends in natural history of the disease, associated socio-demographic parameters & clinico-pathological findings in order to understand the pathogenesis & initiate definitive treatment. Objective: The present article attempts to explore the socio-demographic profile of patients with COM, attending outpatient department in a tertiary care govt. hospital in eastern India & correlate the clinico-pathological features with types of disease, its severity & risk factors for development of complications. Material & Methods: A prospective, cross-sectional, observational study was carried out including consecutive patients with clinical diagnosis of COM. Their socio-demographic profile were recorded through a pre-designed proforma incorporating epidemiologic parameters, clinical & radiological findings. Data was statistically analyzed & correlated with literature review. Results: In the present study, mostly male patients, of lower & upper lower socio-economic class, in the age group 21-30 years were included. Overcrowding was found to be positively associated with the risk of development of COM. Cases were mostly unilateral, mucosal but with a good number of squamous COM. Bad ear hygiene practices were highly prevalent among study population with poor knowledge about the disease. Aural discharge was the commonest presenting symptom followed by deafness. Most of the patients were suffering from the disease for long periods. Mucosal COM mostly caused mild hearing loss, whereas squamous COM caused more severe to profound hearing loss. Most of the central perforations caused mild hearing loss, subtotal & postero-superior marginal perforation caused moderate hearing loss and squamous COM with attic perforation is mostly associated with severe hearing loss. Correlation between congested/ persistently discharging and granulations/polypoidal middle ear mucosa with cholesteatoma was found to be statistically significant. Incus long process was commonly eroded & in the cases without cholesteatoma, granulation tissue in the mastoid antrum was associated with almost all the cases of ossicular necrosis. Duration of disease have been found to possess statistically significant correlation with development of complications, Conclusion: The present study indicates that prevalence of COM can be reduced by avoiding unhealthy habits, improving health status & knowledge about the disease,. Thorough clinical examination & early & definitive manag...

“…9 Rout et al found long process of incus as most commonly eroded ossicle which correlates with our study. 10 In Sinha et al study incus was the most common ossicle involved followed by stapes and malleus which correlates with our study. 11 In a study done by Jahnke and Falk ossicular destruction was found in 77% cases of cholesteatoma.…”

Background: To assess the status of ossicular chain intraoperatively in patients with chronic suppurative otitis media.Methods: This was an observational study carried out in the department of ENT for a period of two years. About 100 patients of CSOM both safe and unsafe type was included in the study. They were then posted for appropriate surgery and their intraoperative ossicular findings were recorded. Results: Out of 100 cases, malleus was found intact in 80 cases, eroded in 17 cases and absent in 3 cases. Incus was the ossicle most commonly found eroded in the study. It was intact in 65 cases, eroded in 29 cases and absent in 6 cases. The most commonly necrosed part was the long process of incus found in 25 cases. Stapes was found to be intact in 77 cases and suprastructure of stapes was eroded in 23 cases.Conclusions: We found malleus to be the most resistant ossicle to erosion in CSOM, whereas incus was found to be the most susceptible. The incidence of ossicular erosion was much greater in unsafe CSOM than in safe CSOM.

This study was conducted to determine the frequency of ossicular chain pathology in case of CSOM (Tubotympanic type). 100 cases of CSOM (Tubotympanic type) were admitted in E.N.T. department for surgery. Per-operative we found ossicular chain erosion as well as tympanosclerosis of ossicles. In our study we found long process and lenticular process are the most susceptible for erosion and malleo incudal joint more commonly involved by the tympanosclerosis.
