Experience of Island Nasolabial Flap for Patients with Oral Cavity Cancer.

Aim: To find out the utility of the island nasolabial flap in patients with oral cavity malignancy.

Materials and methods: This was an observational study conducted at a super-specialty hospital in Maharashtra from October 2019 to December 2021. Patients with oral malignancy planned for island nasolabial flaps were only considered.

Results: A total of 20 patients were operated on, out of which 16 were males and 4 were females. All the patients were followed up for a minimum period of 6 months. The hospital's online reporting system is used for the data collection including the post-operative assessment. Out of the 20 patients, 10 patients were suffering from tongue carcinoma, 6 patients from buccal mucosal carcinoma, two from hard palate carcinoma and one patient each from the floor of the mouth and lip carcinoma. The mean age of the series was 52.3 years, the average duration of the surgery is 169.4 min and the average hospital stay in the series was 4.35 days. The Ryle's tube was removed on an average of 4.35 days. No flap-related complications were noted during the series, and healing of the donor site was uneventful. The functional outcomes after the reconstruction are acceptable in all the cases except in the lip reconstruction patient where there was post-operative drooling.

Conclusion: The island nasolabial flap is relatively easy to harvest and less time-consuming. The other advantages include the post-operative surgical scar falls along the nasolabial fold, long pedicle length with preservation of the facial pedicle for future microvascular use, early transfer to the oral feed from the nasogastric feed, and early de-cannulation. In our small study, we observed that the island nasolabial flap is a very useful flap for the small to moderate-sized defects of the oral cavity. We feel, one of the disadvantages of this flap is that it is not an ideal flap for lip reconstruction.
