Migration of T-tubes to the middle ear.



Editor:

In the Otoscopic Clinic in the January 2008 issue of EAR, NOSE & THROAT JOURNAL, the authors reported otoscopic findings of a migrated tube into the middle ear space. (1) This article, by Abbarah and Abbarah, cites one reference and reports two additional cases. In the April 2008 EAR, NOSE & THROAT JOURNAL, Dr. Hamid comments on that article and reports an additional case of his own. (2)

Interestingly, we reported 4 cases of this problem back in 2002. (3) Our reference was obviously missed in searching the literature. Our impression of this problem was that the tube should be removed, and this was done in all 4 of our cases. Our concern about the persistence of a foreign body in the middle ear cleft stems from its potential to cause a reaction, including chronic otitis media Chronic otitis media
Inflammation of the middle ear with signs of infection lasting three months or longer.

Response:

I would like to thank Dr. Josephson for his stimulating comments on our article regarding the migration of T-tubes to the middle ear and for providing a copy of his article, "Retained tympanostomy tubes in the middle ear cleft: An uncommon complication of tube placement." My reply is that we reported only on T-shaped ventilation tubes (modified Richards T-tube), and the reference we mentioned in our article also reported on T-shaped ventilation tubes (Goode T-tube). These tubes have large flanges, a long shaft, and are designed for long-term ventilation.

Dr. Josephson's article dealt with the migration of tympanostomy tubes in general. There are at least 50 kinds of tyrnpanostomy tubes. Migration of these tubes to the middle ear cleft is rare, but it was reported in the literature almost 30 years ago. (1)

I am in agreement with the removal of the tubes in the 4 cases reported in Dr. Josephson's article, since each case was associated with signs and symptoms requiring removal of the tube, but removal of a silent migrated tube without signs or symptoms is a matter of opinion, since there are no hard data to outline the management of this rare entity. However, there are some authors sharing Dr. Josephson's view in this regard. (2)
