[The complex pediatric middle ear hemangioma].

Hemangiomas in the pediatric middle ear are a rare occurrence. We present the case of a 3-year-old boy with unilateral hearing impairment and recurrent otitis media with effusion due to a hemangioma in the middle ear. This caused a venous sinus thrombosis, osteomyelitis, and mastoiditis. Interdisciplinary treatment was performed. This case shows that even benign lesions in the middle ear can cause severe, life-threatening complications due to the close proximity of important anatomic structures in the middle ear. Every case of asymmetric hearing loss should thus be examined in detail.
