Abstract
Between 40 and 90% of tympanoplasty require middle ear ossicular chain reconstruction. Ossicular discontinuity usually cannot be determined unless an operation is performed. The main objective was to determine the predictive value of pre-operative audiological factors in diagnosing incudal necrosis in patients with tubotympanic chronic suppurative otitis media. A retrospective clinical study of 20 patients who underwent ossicular reconstruction with autologous incus over a period of two years was performed. The mean pre-operative pure tone average was 49.18 dB HL.The minimum value being 45 dB HL and the maximum value being 64 dB HL.
