선택적 전기지짐을 위한 앞관자신경의 주행경로에 대한 국소 해부학적 연구

초록

Bilateral hypertrophy of the temporal muscle can give the impression of a aggressive and violent facial appearance. We supposed a closed selective denervation of the deep temporal nerve using electrocauterization. Before the practice, precise anatomical knowledge of deep temporal nerve is mandatory. Sixteen hemifaces of Korean cadaver were dissected. To standardize the position of the anterior division of the deep temporal nerve, we recorded the distance from six anatomical landmarks to the nerve. In 19 percent (3 of 16 cadavers), one deep temporal nerve was observed and in the remainder, two deep temoral nerves were identified. In all of our specimens, mean three(range 1-4)temporal branches also arose from the buccal nerve. One temporal branch arising in common with the masseteric nerve was observed in 2 of 15 our specimen. On the infratemporal crest, distance from the anterior division of the deep temporal nerve to posterior division of the deep temporal nerve and masseter nerve was 4.7±0.9mm(range3-6mm) and 8.3±1.1(range 6-10mm)mm. On the superior surface of the zygomatic arch, distance from the most concave point of zygomatic bone(point A) to anterior division of the deep temporal nerve was 19.4±1.2mm(range 18-21mm). On the inferior surface of the zygomatic arch, distance from the prominent point of the condylar process of the mandible to the anterior division of the deep temporal nerve was 22.3±1.6mm(range 22-25mm). Great consistency in position of anterior division of deep temporal nerve was shown. The results of this study could provide a basis, for closed selective denervation of anterior division of deep temporal nerve using electrocauterization. The clinical application is needed.
