Purpose:
To describe the surgical technique using a 10/14 French silicone urinary catheter as a novel tissue expander for repair of defects after removal of eyelid tumors. This device recruits additional tissue by tissue expansion for repair of large eyelid defects.
Methods:
A prospective noncomparative, interventional case study was conducted over a period of 3 years in which 30 patients were enrolled. All the 30 patients were selected for upper or lower lid Tenzel rotational flap after removal of large malignant tumor, using the tissue expander.
Results:
A 10/14-French silicone urinary catheter was placed in the periocular region and expanded by graded inflation with normal saline to a total volume of 10 or 14 ml, respectively, over a period of 3 days. On the fourth day before the planned surgery, the catheter balloon was deflated and a modified Tenzel rotational flap was performed to close the defect. Postoperative blink reflex was preserved. There were no cases of wound dehiscence. There was a significant reduction of incision length in upper and lower lid reconstruction with modified Tenzel flap reconstruction.
Conclusion:
This approach allows for temporary tissue expansion, permitting the closure of large eyelid defects, typically not possible with a conventional Tenzel flap. This also provides excellent functional outcomes without closing patients' eyelids (which limits vision for weeks to months) as is typical of other reconstructive modalities (e.g. Cutler Beard procedure). The device is cost-effective and readily available. The authors believe it is an excellent alternative in the developing world where access to more expensive options is limited.
