Özet
Özellikle iki taraflı nazolabial flep operasyonlarından sonra dudağın denervasyon problemleri olabileceği düşünülmüştür. Biz sukuamoz karsinoma sonrası beş olguda ortaya çıkan defektleri nazolabial "gate" flap ile onardık. Dudak innervasyonunu postoperative dönemde EMG ile araştırdık.Erken postoperative dönemde bile dudağın innervasyonu olduğunu gözledik. Bu klinik bulgu sonrası beş kadavra üzerinde bir anatomik çalışma yaptık ve 10 nazolabial flebi dudağın innevasyonunu araştırmak için kaldırdık. Bu çalışma sırasında üst dudağa sinir iletimine izin veren nazolabial flebin en üst kenarı ile piriforum aperturanın lateral kenarı arasında bir alan lokalize edildi. Ardından bu alandan nekropsiler alındı ve çok fazla sinir dokusu histolojik incelemede gözlendi. Sonuç olarak nazolabial "gate" flap bilateral olgularda bile dudak rekonstrüksiyonunun innerve dokularla yapıl-masına olanak sağlayan iyi bir flep seçeneğidir.
Dernervation problems of the lip both the upper lip and reconstructed lower lip have been considered possible after nasolabial flap procedures particularly in bilateral cases. We performed gate flap operations in five patients for lip defects due to squamous carcinoma excision. Lip innervation was investigated with EMG studies in the postoperative period. We observed that innervation of the lip was present in early postoperative period. After this clinical finding an anatomic study was performed on five cadavers. Ten nasolabial flaps were elevated to examine lip innervation. An area which can permit neural pathways for upper lip was localized between the most cephalic borders of the nasolabial flap and the lateral wall of the pyriform apertura then .Then necropsies were identified with histologic examination. In conclusion, nasolabial "gate " flap provides ideal lower lip reconstruction with innervated tissue and upper lip innervation is protected with bileteral gate flap operation
