IntroductionReconstruction of the eyelids is a challenging task for plastic and reconstructive surgeons and is mostly performed due to trauma, tumor resection, or, less commonly, congenital abnormalities (e.g., coloboma, Tessier no. 3-6 clefts) (1,2). The decision as to the most appropriate reconstructive option depends on assessment of the eyelid defect in terms of its size, extent, orientation, and, most importantly, location. A method of classifying periocular defects according to location was developed by Spinelli and Jelks (3), in which the eyelid was divided into 5 zones: zone I, the upper eyelid; zone II, the lower eyelid; zone III, the medial canthal region; and zone IV, the lateral canthal region. Furthermore, any area outside zones I-IV but contiguous with the eyelids was described as zone V in this classification system (Figure 1).Full-thickness defects up to 25% of the width of the lower eyelid can be repaired via direct closure. Lateral canthotomy and cantholysis can provide 25% additional horizontal length, leading to tissue advancement and rotation to aid in closure of larger defects (1,3,4). When primary closure is not feasible, various flap alternatives developed with the aims of functional restoration and aesthetic improvement of the lower eyelid zones can be employed, such as the semicircle (Tenzel) flap ( 5), superiorly based tarsoconjunctival advancement (Hughes) flap (6), upper eyelid myocutaneous (Tripier) flap (7), transposed cheek (McGregor) flap (8), cheek rotation and advancement (Mustardé) flap (9), and supraorbital (Fricke) flap (10).Nasolabial flap is rarely employed for the reconstruction of the lower eyelid. It is a random-pattern cutaneous flap with redundant blood supply from the perforating branches of the facial and angular arteries and can be used as an inferiorly or superiorly based flap (11,12). It has a wide spectrum of use for nasal and midfacial defects (13,14) and can be used as an island (15) or transposition flap (16-18) for the reconstruction of the lower eyelid.In this study, we aimed to present the clinical results of using the superiorly based nasolabial island flap for repair Background/aim: Various flap procedures have been described and used for the lower eyelids; however, the nasolabial flap is rarely employed. We herein aimed to present the clinical results of using the superiorly based nasolabial island flap for repair of surgical defects extending to the lateral lower eyelid.
Materials and methods:Nine patients with a mean age of 62 ± 6 years underwent surgery for reconstruction of the lower eyelid.
Results:The diagnosis of lesions was nodular basal-cell carcinoma (n = 5), superficial basal-cell carcinoma (n = 1), well-differentiated squamous-cell carcinoma (n = 1), and basosquamous-cell carcinoma (n = 2). According to the classification reported by Spinelli and Jelks, 6 surgical defects were located at zones II and IV, while 3 were at zones II and V. Five patients required posterior lamellar reconstruction. Lagopthalmos (n = 1), ectropion (n = 1), and trans...
