Plastic surgery of tympanic membrane defects with multilayer grafts

There is large number of publications on the short- and long-term anatomical and functional outcomes of using different grafts in closing of total and subtotal tympanic membrane defects. This confirms the continuing relevance of choosing the material for a transplant. During the study, carried out in the otorhinolaryngology clinic of the Kirov Military Medical Academy, we had compared the results of different cartilage grafts applying in myringoplasty: auricular autocartilage, nasal septum autocartilage, or allogeneic costal cartilage. The study included patients with normal auditory tube function. Overlay technique was applied in all cases. The effectiveness of myringoplasty was assessed by clinical-morphological and functional results after 1 month and after 1 year after surgery. Ad oculus evaluation was carried out according to the neotympanic membrane morphological criteria scale after O.N. Borisenko, the function was assessed using tympanometry data. As a result of the study, we had found that all grafts have good sound-conducting properties and can be successfully used in myringoplasty in patients with chronic otitis media. However, using grafts with a septal autocartilage and allogeneic costal cartilage have advantages over an auricular autocartilage applying.
