“…In our study pneumatisation of affected ear was sclerosed in majority of cases which is in agreement with other studies as pneumatisation gets poorer with growing chronicity of the disease, similar where 78.75 % of mastoid sclerosed in study by Amitava. 16 In our study majority of cases were of mucosal type of COM hence cortical mastoidectomy with tympanoplasty was done and in 7 cases modified radical mastoidectomy was done were 2 cases were revision mastoidectomy. None of the patient had any postoperative complications.…”

Background: Chronic otitis media (COM) is a serious healthcare concern worldwide, because of the distress and economic burden to the patient and their family. Temporal bone pneumatization plays an important role in etiology, behaviour, course and outcome of COM. Pneumatisation gets poorer with growing chronicity of the disease. Methods: A retrospective study was conducted between March 2015-March 2017 on female patients visiting with COM, at ENT department Kasturba Gandhi Hospital, Madras Medical College. The records were analysed of the age, duration of symptoms, associated complaints, pure tone audiogram, computerised tomography of temporal bone, mastoid surgery done according to the disease process affecting the ear. Results: 35 female COM patients were analysed, most common age group is between 31-40 years in 14 patients. There hearing loss was mild category in 27. There were 27 cases of mucosal type of chronic otitis media and 8 cases of squamous type. The CT scan with sclerosis of mastoid was the common finding. Conclusions: In exclusive study on female patients with COM, the mucosal type of COM is common with mild hearing loss and sclerosed mastoid indicating the chronicity.

“…7 Another study done by Roy et al reported that pneumatisation was seen in 42.6%, diploic in 31.43% and sclerosis in 25.71% patients. 8 In mucosal CSOM ,79% had type Atympanogram,12% had type B and 8.8% had type C whereas in squamosal CSOM 61.53% had type A, 19.23% had type B and 19.23% had type C in CLE. It was in accordance with Jadia et al where they reported Type A in 71% and Type B in 29 % patients.…”

Background : The contralateral ear (CLE) is defined as the asymptomatic ear in unilateral chronic supportive otitis media (CSOM). Prevalence in India was found to be around 7.8% which is highest globally. Aims and Objectives : To compare audio logical and radiological CLE findings with the mucosal and squamosal types of CSOM. Materials and Methods: Three hundred CSOM patients were studied in the Department of Otorhinolaryngology and Head and Neck Surgery from February 2017 to August 2018. All the patients were examined with otoscope. Pure tone audiometry, X-ray mastoids lateral oblique view, tympanogram and CT scan temporal bone were performed. Results: CSOM was more prevalent among females (54%) of young age group (41.6%).In mucosal CSOM, in diseased ear maximum patients (56.85%)had hearing loss between 25-40 dB, while in squamosal CSOM, majority patients (38.4%)had 40-55 dB hearing loss. In contralateral ear of mucosal CSOM maximum patients (85%) had 15-25 dB hearing loss, while in squamosal CSOM, 71.1% had 15-25 dB hearing loss. In mucosal CSOM, majority had type Atympanogram (79.03%) in CLE whereas in squamosal CSOM, 61.53% had type A tympanogram. Conclusion: Incidence of abnormality in CLE was high in patients of unilateral CSOM. Both ear should be considered together as development of CSOM is a continuous process and can affect both the ears.

“…Roy et al discovered that 1.92% of mastoids were pneumatized, 19.23% were diploic, and 78.85% were sclerotic. Contralateral normal mastoids were pneumatized in 42.86% of cases, diploic in 31.43%, and sclerotic in 25.71% of instances [ 21 ]. Sadé observed an 82.3% association between a low or non-pneumatized mastoid and squamosal COM, whereas Gomaa et al reported a 60.7% association [ 14 , 22 - 24 ].…”

Chronic otitis media is generally more prevalent in individuals with a weakly pneumatized temporal bone, whereas acute otitis media has a propensity for pneumatized temporal bone. Antimicrobial drugs are thought to have influenced the incidence and progression of middle ear infections. The mastoid air cell system, a part of the middle ear cleft, has recently been recognized as a crucial factor in the genesis, behaviour, course, and outcome of middle ear inflammatory conditions. Epithelium infiltrates the growing bone and produces epithelium-lined air cell chambers, a process known as pneumatization.Conventional temporal bone radiography, i.e. X-ray mastoid, has not kept up with recent otology breakthroughs. Detailed visualization of the aural structures has advanced significantly with the introduction of high-resolution computed tomography (HRCT). HRCT has a clear edge in the assessment of the temporal bone, especially when thin-section, high-resolution methods are used, resulting in a more precise description of the pneumatization pattern and the anatomical extent of middle ear pathology.Our results of the review indicated that persistent inflammation of the middle ear in children inhibits pneumatization of the temporal bone. Due to its potential to exert a greater negative middle ear pressure, the middle ear volume is insufficient to generate a retraction pocket; thus, the size and state of the antrum is also a significant factor in the establishment of a COM-like retraction pocket in inactive squamosal disease. Numerous factors, including the number of patients, regional, genetic, ethnic and hereditary characteristics, as well as the cellularity of the mastoid, which is impacted by a multitude of factors, may account for the variable reports and inter-study variation in this regard.
