 Congenital ossicular malformations have been dealt as a common disease and detected at an early age because of generalized school medical examinations and higher success rate of surgery. However, cases of delayed diagnosis of hearing loss with otitis media and effusion have been observed. We present the case of 13 year-old boy with hearing loss of 61.3 dB. Preoperatively, elevated bone hearing level at 4000 Hz and disappearance of the stapedial reflex were observed. Computed tomography revealed incus dislocation and illegible stapes. Exploratory tympanotomy revealed the long processus of the incus and superstructure of the stapes. Although the disappearance and dislocation of the incus with small granulation were observed, cholesteatoma was not detected and hearing level improved to 31.3 dB postoperatively. Although the patient was diagnosed with a congenital ossicular malformation with inflammation due to intubation, congenital cholesteatoma resolved spontaneously.
