Tracheocutaneous Fistula Closure: Comparison of Rhomboid Flap Repair with Z Plasty Repair in a Case Series of 40 Patients.

INTRODUCTION: Tracheocutaneous fistula (TCF) is one of the recognized sequelae of a long-term tracheostomy resulting from mucocutaneous overgrowth which prevents closure of the artificial lumen at the site of tracheostomy. Primary closure of TCF has disappointing results and may lead to complications like pneumothorax, pneumomediastinum, cervicofacial subcutaneous emphysema, and depressed scar.

OBJECTIVE: To compare TCF repair using fistulectomy followed by rhomboid flap versus fistulectomy followed by Z plasty repair.

METHODS: In this prospective study, 40 patients of either sex with persistent TCF were included. All patients were randomly divided into two groups. Group I had 20 patients who underwent TCF repair using a technique in which fistulectomy was done followed by its closure in layers, and finally closing the defect using a rhomboid flap. The remaining 20 were included in group II who underwent TCF repair using a technique in which fistulectomy was done followed by layered closing, and final closure of the defect was done using Z plasty. The follow-up period was 3 months.

RESULTS: Out of 40 patients, all but 8 experienced a successful outcome without any complications, and complete aesthetic satisfaction, with improvement in phonation, and no soiling of clothes with mucus or sputum. The 8 unsuccessful patients belonged to group II (Z plasty group).

CONCLUSION: Both techniques have been described in the literature and are proven to give good results. Our study emphasizes the fact that in our experience, the rhomboid flap was a better alternative for TCF repair than Z plasty.
