This study aimed to provide our design and experiences for such reconstructive purpose.  \nMethods: Patients with lower lip or oral commissural cancer who received curative surgery involving reconstruction with inferiorly based nasolabial flap were included. The demographic data and clinical outcomes of these patients were obtained by retrospective chart review.  \nResults: A total of eight patients were enrolled in this study. All patients received ablative surgery at the National Cheng Kung University Hospital during May 2019 to May 2021, with their surgical defects reconstructed with unilateral inferiorly based nasolabial flap successfully. Among the five patients with lower lip cancer, one had a limited area of necrosis at flap tip. Another patient had a small orocutaneous fistula that healed spontaneously. No trismus or oral incompetence was noted following recovery. For the three patients with commissural cancer, a second stage commisuroplasy was needed after primary reconstruction. One patient had limited wound dehiscence at mouth angle following surgery, resulting in mild oral incompetence. Although mild trismus was noted in these three commissural cancer patients, all patients resumed normal diet during follow-up.  \nConclusion: Inferiorly based nasolabial flap is an excellent local flap for lower lip reconstruction following cancer ablative surgery. It is also a viable option for reconstruction of oral commissural defects. Minimal donor side morbidity, good functional recovery, and esthetic outcomes can be achieved with meticulous flap design.  \nKeywords: Esthetic; Fistula; Morbidity; Necrosis; Trismus  \n1. INTRODUCTION  \nSquamous cell carcinoma (SCC) of the lip accounts for more than 25% of all oral cancers, with more than 90% of cases occurring in the lower lip.1 Surgical resection is still the mainstay treatment of lip SCC. Although a 5-year overall survival around 70% can be achieved in lip SCC patients,1 the resulting facial disfiguring and oral dysfunction can significantly impair a patient’s quality of life. Since both facial contour and oral competence have to be restored simultaneously, reconstruction of lip and commissural defects following ablative cancer surgery remains challenging.  \n* Address correspondence.
