INTRAOPERATIVE FINDINGS OF OSSICULAR CHAIN STATUS IN CHRONIC OTITIS MEDIA: OUR EXPERIENCE IN A TERTIARY CARE CENTRE

Background: Chronic otitis media (COM) is a permanent abnormality of the pars tensa (PT) or pars accida (PF) which may manifest in the form of atelectasis, perforation, tympanosclerosis, retraction pocket development, cholesteatoma, cholesterol granuloma, ossicular chain disruption etc. It has been further subdivided into active and inactive forms or Safe tubotympanic variety and Unsafe atticoantral variety. COM of all types is associated with erosion of the ossicular chain . The incidence and degree of ossicular destruction is much greater in cases of unsafe COM due to the presence of cholesteatoma and/or granulations .The aim of the present study was to correlate the type of COM, the site of perforation/retraction and the type of disease pathology with the pattern and degree of ossicular chain necrosis. Aims and objectives: AIM OF THE STUDY: To study the ossicular chain involvement in both safe and unsafe types of COM in patients attending to E.N.T. Department of a tertiary care hospital OBJECTIVES: 1. To study the incidence of ossicular chain pathology in both types of COM. 2. To study the frequency and type of involvement of each ossicle. 3. To compare the ossicular chain involvement in tubotympanic and atticoantral variety of Chronic otitis media.. Methodology: A prospective study was performed in 90 cases of COM who were subjected to tympanomastoidectomy in tertiary care hospital for a period of 1year from January2019 to December 2019. Pre-operative clinical and audiometric ndings were compared with per-operative ossicular chain status. Results: Ossicularinvolvement is seen in both types of COM more in unsafe type of COM. Incus is the most commonly affected ossicle while malleus is the least affected ossicle. Conclusion: Ossicular chain status should be checked in all patients with COM. So otolaryngologists should be able to address the ossicular chain reconstruction to give the best hearing outcome to the patient.

Flap Elevation

Background: Tympanoplasty is the commonest procedure performed in patients with chronic otitis media. Circumferential elevation of tympanomeatal flap and underlay graft placement is thought to be a good surgical technique as it ensures elevation of canal skin over the Eustachian tube area to form a good assemble between the temporalis graft and the flap to increase the success rate. In our study we intend to study the surgical and hearing outcome in patients undergoing tympanoplasty with circumferential tympanomeatal flap in large central perforations.Methods: A prospective study with 25 patients in a tertiary care hospital for a period of 2 years, who underwent circumferential tympanomeatal flap tympanoplasty. Patients were followed up on one month and two months. Graft outcomes and hearing outcomes were studied. Results: Graft uptake was 92%. Blunting was noticed in 4% and medialisation in 4% of patients in circumferential group. Average air-bone gap closure achieved was 17.468 dB.Conclusions: Circumferential flap elevation in tympanoplasty is an effective surgical technique in patients with anterior and large central perforations with satisfactory outcomes.
