Extra-annular T tubes: a case series.

OBJECTIVE

to review the efficacy of extra-annular T tubes in a cohort of patients.

DESIGN

case series of 50 patients undergoing 60 extra-annular T-tube insertions.

SETTING

district general hospital.

METHODS

retrospective review of case notes.

MAIN OUTCOME MEASURES

extrusion, chronic perforation after extrusion, infection, occlusion.

RESULTS

Sixteen of 60 tubes extruded at an average of 16 months after insertion. Two tubes had to be removed. One of 18 extruded/removed tubes was associated with a chronic perforation. Seven of 60 tubes became infected during the follow-up period, none of which required removal. Of the 42 tubes that did not extrude or have to be removed, the average follow-up was 23 months.

CONCLUSION

our case series of extra-annular tubes suggests that this procedure is a safe intervention for long-term middle ear ventilation with a low rate of infection and chronic perforation.
