Middle-ear lipoma as a cause of otomastoiditis.
We present a case report which describes a rare cause of a common clinical problem; eustachian tube dysfunction. A seven-year-old child presented with a history of chronic draining ears, despite rigorous medical therapy and multiple ventilation tubes. At myringotomy a mass was noted in the middle ear, and she was taken to the operating room for exploration. The patient was found to have a pedunculated lipoma arising from the anterior medial aspect of the middle-ear cleft producing intermittent obstruction of the eustachian tube orifice. This case represents the fourth case of a middle-ear lipoma in the world literature. We present a review of the literature and an exploration of possible aetiologies of this unusual entity in the differential diagnosis of eustachian tube dysfunction.
