A study of various graft materials used for ossicular chain reconstruction at tertiary health care centre
Journal Title: Medpulse International Journal of ENT - Year 2018, Vol 5, Issue 1
Abstract
Background: The middle ear ossicles are uniquely shaped structures that collect sound waves from the tympanic membrane (TM) and conduct them to the inner ear. Infective agents, inflammatory processes, and trauma can prevent the normal functions of these structures. Ossiculoplasty involving ossicular chain reconstruction using graft materials is frequently used in the treatment ofconductive hearing loss. Aim and Objectives: To study operative ease and post-operative hearing results in patients undergoing ossicular chain reconstruction with different types of prostheses. Material and Methods: A prospective randomized study of 30 patients with Chronic Otitis Media, undergoing ossiculoplasty was conducted at a tertiary health care centre. The ossicular chain was reconstructed with a tragal cartilage, conchal cartilage, refashioned incus, hydroxyapatite and titanium prostheses in 06 patients each. Subjects with mixed hearing loss, multiple co-morbidities and revision surgeries were excluded. Hearing assessment was done by pure toneaudiometry pre-operatively and 04 and 12 weeks postoperatively. Results: Among the patients studied, male to female ratio was 2:3 and a maximum of individuals belonged to third and fourth decades of life. Using synthetic material for grafting during the procedures saved time. Compared to others, titanium prosthesis gives maximum surgical ease. Post-operative air-bone gap reduction within 20 dB was seen in all, irrespective of type of prostheses. Conclusion: Patients those were managed surgically showed considerably better outcome with titanium prostheses; however the improvement seen in Air-Bone gap reduction was equally noticed with all types of graft materials used. Key words: Chronic otitis media, Ossicular Chain reconstruction.
