Chronic Suppurative Otitis Media (CSOM) is a chronic inflammation of middle ear cleft. It presents with discharging ear and decreased hearing. The diagnosis is mostly on clinical examination with otoscope or oto endoscope. Computerised Tomography (CT) of mastoids is done to evaluate the extent of the disease and its complication. High resolution CT is now the investigation of choice for temporal bone disease. This study emphasizes on the importance of CT scan in diagnosis of inflammatory ear diseases and most importantly identifying pitfalls or complications which a surgeon can come across during surgery. The aims and objectives of this study is (1) to establish the efficacy of CT in the diagnosis of the complications and surgical management of chronic inflammatory pathologies of middle ear. (2) To find subgroups of CSOM where CT is particularly useful. In this series, a total of 25 cases presenting to our OPD at Govt. ENT Hospital between 2013 and 2014 have been diagnosed and findings of surgery correlated with HRCT scan of temporal bones done preoperatively. In this study, 64 % of the patients were male and incidence of CSOM with patients undergoing surgery belonged to the age group 21-30 years (32 %). The most common presenting symptom was ear discharge (92 %) and decreased hearing (96 %). The most common type of pathology in this study was attic perforation (36 %) and granulations (40 %) followed by cholesteatoma (36 %) and mucosal edema (16 %). Not all cases presented with complications, facial palsy (12 %) and mastoid abscess (8 %) were among few complications seen. 14 patients (56 %) of 25 cases underwent simple cortical mastoidectomy followed by 9 cases (36 %) for modified radical mastoidectomy and atticotomy for 2 cases (8 %). CT scan findings correlated well with surgical findings for cholesteatoma, middle ear mass and bone erosions. Where as for ossicular integrity and facial canal dehiscence, there was a discrepancy.

“…It can coexist with FND, may be due to the proximity to facial nerve, as described in previous studies. [14][15][16][17] In our study also, a statistically significant positive association was noticed between facial canal dehiscence and presence of lateral semicircular canal fistula.…”

“…The incidence of facial canal dehiscence has been estimated in several studies ranging from 3% to 40%. [14][15][16][17] In our study the incidence of FND was 17.5%, mostly affecting the tympanic segment and one patient had iatrogenic facial injury which required re-exploration. High resolution computer tomography of temporal bone can be used to alert the surgeon to potential intraoperative dangers and complication associated with the particular surgery.…”

Background: Mastoidectomy is a common otologic surgery and at times can be a lifesaving procedure. The aim of the study is to analyze surgical indications, operative parameters and per-operative findings encountered. Methods: This is a retrospective study done in patients who had undergone mastoid surgeries between 1 st Jan 2016 to 31 st Dec 2016 in the Department of Otorhinolaryngology, Govt. Medical College hospital, Trivandrum. Results: Of the 137 patients the peak age incidence was 16 -30 years. Cholesteatoma was present in 32% of which 91% had canal wall down mastoidectomy. 64% patients, mostly chronic otitis media-mucosal and inactive squamosal, underwent canal wall up procedure. In 62% cases the ossicular chain was eroded, which was mainly incus (87%). Abnormalities encountered within the mastoid during surgery were mainly dehiscent facial canal (17.5%), low lying dura (16.8%) and contracted antrum (15.3%). A positive association could be noted between contracted antrum and the position of sinus and dural plates, and was statistically significant. Co-existence of facial canal dehiscence with lateral canal fistula and dural plate dehiscence were also noted. The tympanoplasty procedures commonly employed in canal wall up procedures was Type I and 2, and in canal wall down procedure was Type 3. Conclusions: Adequate skill development of the ear surgeons in the tertiary centre should be ensured, to individualize the procedure appropriate for each patient and optimize the outcome of surgery. Early referral to the nearby otological centre should be promoted not only to prevent complications but also for better post-surgical functional outcome.
