Case of perilymphatic fistula caused by medially displaced tympanostomy tube.

ABSTRACT

OBJECTIVE: We present a rare case of perilymphatic fistula which occurred due to bony erosion by a tympanostomy tube that had migrated into and become interred in the middle-ear space. METHOD: We present a case report and a literature review concerning migration of tympanostomy tubes into the middle ear as a complication of tubes insertion. CONCLUSION: Medial migration of tympanostomy tubes into the middle-ear space is a rare complication of tympanostomy tubes insertion. To our knowledge, this is the first report of perilymphatic fistula caused by a tympanostomy tube which had migrated into the middle ear. This case highlights the need for early removal of tympanostomy tubes which migrate into the middle ear.
