T-tubes Through Cartilage Tympanoplasty: Is It Worth the Perforation Risk?

Area of Science:

• Otolaryngology
• Surgical Innovation
• Middle Ear Surgery

Background:

• Chronic ear conditions often require long-term middle ear ventilation.
• T-tubes are commonly used for this purpose, but their placement and impact on the tympanic membrane are critical considerations.

Purpose of the Study:

• To evaluate the long-term outcomes of T-tube placement through cartilage tympanoplasty versus native tympanic membrane.
• To compare residual perforation rates after T-tube removal in both techniques.

Main Methods:

• Retrospective chart review of 116 patients (122 ears) undergoing cartilage tympanoplasty with T-tube placement.
• Comparison of T-tube retention, patency, and tympanic membrane status post-removal between total island cartilage and posterior palisade graft techniques.

Main Results:

• Three residual perforations (4.4%) occurred in the cartilage tympanoplasty group (n=68 T-tubes).
• Six residual perforations (8.5%) occurred in the native tympanic membrane group (n=71 T-tubes).
• Mean T-tube retention was 3.93 years (cartilage) and 3.58 years (native tympanic membrane).

Conclusions:

• T-tube placement through cartilage tympanoplasty provides durable middle ear ventilation.
• This technique does not elevate the risk of residual perforation compared to placement through the native tympanic membrane.
