International Journal of Dentistry and Oral Science (IJDOS) ISSN: 2377-8075 Introduction Nasolabial fap (NLF) appears to have been originally described in the works of Susruta in 600 BC [1]. It was there after used primarily in external reconstruction of nose for centuries. The transbuccal use of nasolabial fap for the closure of the oral cavity was frst described by Thiersch [2]. There are various modalities that have been described for recon- structing the intra and extra-oral defects that cannot be managed by primary closure. They can be either pedicled or free faps, however, sometimes these techniques are not feasible because either defect is too small or patient’s age and medical status do not permit a lengthy anaesthetic and surgical procedure. In such circumstances nasolabial fap stands the only available option, that can serve the situation for repair of small or moderate-sized local intra and extra-oral defects [3]. Very large defects of the lip are diffcult to reconstruct. The main goal of a lip reconstruction is to re-establish aesthetics and oral competency that can allow normal function. Although several methods of lip reconstruction has been described in the litera- ture, no technique has been proven to be the ideal one that suf- fces all requirements. Many authors advocate musculocutaneous tissue transfer to recreate the anatomical component of the lip, as they believe that the muscle must be transferred into the defect to maintain oral competence [4]. The technique of composite tissue transfer (e.g. Karapandzic fap) is interesting but its use is limited, as the quantity of orbicularis oris muscle is sparse and these pro- cedures often lead to signifcant microstomia [5]. Limited quantity of muscle often get denervated during secondary commissuro- plasties, which is performed to correct microstomia. Final result after many procedures often ends in patients with an immobile *Corresponding Author: Dr. Nitesh Mishra, Senior Resident, Room no.16, Block B, Resident Doctor Hostel, Kalpana Chawla Government, Medical College and Hospital, Karnal, Haryana, Pincode-132001, India.

Abstract In the present era of medical advancement, the concept of a microvascular free fap technique has signifcantly gained popu- larity in the reconstruction of head and neck surgical defects. Therefore, the routine need for various local and regional faps that were previously in use, has decreased to a considerable extent. However, a number of such local and regional faps are quite useful and are still in practice, being used by the reconstructive surgeons. Nasolabial fap is a versatile, reliable, simple, easy to harvest local fap that can cover a variety of intra and extraoral defects. In this case series, we present the success and utility of bilateral nasolabial fap in reconstruction of two large lower lip defects and the restoration of function and aesthetics. The patients had been followed for one year, which was uneventful with no signs of recurrence. Keywords: Squamous Cell Carcinoma; Lower Lip Defect; Bilateral Nasolabial Flap.
