Middle Ear Ceruminous Gland Adenoma Obstructing the Eustachian Tube Orifice

Figure 1

Preoperative (a–c) and postoperative (d–f) clinical findings. (a) Preoperative otoendoscopic examination revealed a pinkish mass-like lesion (black arrow) behind the anterior portion of the tympanic membrane. Middle ear effusion is observed (white arrow) despite previous ventilation tube insertion (black arrow head). (b) Axial view of temporal bone computed tomography (TBCT) demonstrated soft tissue density obstructing the bony portion of the Eustachian tube (black arrow) and mastoiditis (white arrows). (c) Pure tone audiometry showed conductive hearing loss with an air-bone gap of 37 dB in the left side. (d) Postoperative otoendoscopic examination revealed normal tympanic membrane. (e) Axial view of TBCT demonstrated a clean mastoid cavity (white arrow) and no residual mass in the bony portion of the Eustachian tube (black arrow). (f) Pure tone audiometry showed that the air-bone gap was reduced to 5 dB in the left side.
