This study was carried out to investigate the branch and distribution of Nervus facialis of the Korean native goat. The observation was made by dissection of embalmed cadavers of ten Korean native goats. The results were as follows; 1. N. facialis arose from the ventrolateral surface of the medulla oblongata. 2. In the facial canal, N. facialis gave off N. petrosus major, N. stapedius and Chorda tympani. 1) N. petrosus major arose from Ganglion geniculi, passed through the pterygoid canal and terminated in Ganglion pterygopalatinum. 2) Chorda tympani joined N. lingualis at the lateral surface of the internal pterygoid muscle. 3. At the exit of the stylomastoid foramen, N. facialis gave off N. caudalis auricularis, Ramus auricularis internus, Ramus stylohyoideus and Ramus digastricus. 1) N. caudalis auricularis arose by two branches in 6 cases and by a single branch in 4 cases. N. caudalis auricularis gave off branches to the caudoauricuIar muscles and the internal surface of the conchal cavity. 2) Ramus auricularis internus arose by a single branch except in 2 cases in which it arose in common with N. caudalis auricularis. It penetrated the caudolateral surface of the tragus and distributed in the skin of the scapha. 3) Ramus stylohyoideus and Ramus digastricus arose separately from N. facialis. 4. In the deep surface of the parotid gland, N. facialis divided into N. auriculopalpebralis, Ramus buccalis dorsalis and Ramus buccalis ventralis. In 6 cases, N. facialis gave off Ramus buccalis ventralis and then divided into N. auriculopalpebralis and Ramus buccalis dorsalis. In 3 cases, N. facialis trifurcated into Ramus buccalis ventralis, Ramus buccalis dorsalis and N. auriculopalpebralis. In one case, N. facialis gave off N. auriculopalpebralis and then divided into Ramus buccalis dorsalis and Ramus buccalis ventralis. 1) Ramus buccalis ventralis ran along the ventral border of the masseter muscle and distributed to the buccinator and depressor labii inferioris muscles. Ramus buccalis ventralis communicated with a branch of Ramus buccalis dorsalis and N. buccalis. In 2 cases, it also communicated with N. mylohyoideus. 2) Ramus buccalis dorsalis communicated with Ramus transverses faciei, N. buccalis, N. infraorbitalis and a branch of Ramus buccalis ventralis. Ramus buccalis dorsalis distributed to the orbicularis oris, caninus, depressor labii inferioris, levator labii superioris, buccinator, malaris, nasolabialis and zygomaticus muscles. 3) N. auriculopalpebralis gave off Rami auriculares rostrales, which supplied the zygomaticoauricularis muscle, the frontoscutularis muscle and the skin of the base of the ear. N. auriculopalpebralis then continued as Ramus zygomaticus, which innervated the frontal muscle, the lateral surface of the base of the horn, the orbicularis oculi muscle and the adjacent skin of the orbit. N. auriculopalpebralis communicated with Nn. auriculares rostrales and Ramus zygomaticotemporalis. In 7 cases, it also communicated with N. infratrochlearis.

The depressor anguli oris (DAO) muscle is a thin, superficial muscle located below the corner of the mouth. It is the target for botulinum neurotoxin (BoNT) injection therapy, aimed at treating drooping mouth corners. Hyperactivity of the DAO muscle can lead to a sad, tired, or angry appearance in some patients. However, it is difficult to inject BoNT into the DAO muscle because its medial border overlaps with the depressor labii inferioris and its lateral border is adjacent to the risorius, zygomaticus major, and platysma muscles. Moreover, a lack of knowledge of the anatomy of the DAO muscle and the properties of BoNT can lead to side effects, such as asymmetrical smiles. Anatomical-based injection sites were provided for the DAO muscle, and the proper injection technique was reviewed. We proposed optimal injection sites based on the external anatomical landmarks of the face. The aim of these guidelines is to standardize the procedure and maximize the effects of BoNT injections while minimizing adverse events, all by reducing the dose unit and injection points.

구강안면통증의 주원인의 하나인 측두하악장애는 다양한 기여요인에 의해 발생하거나 악화되는데, 특히 이갈이, 이악물기 등의 비기능적 구강악습관은 중요한 기여요인으로 고려된다. 구강악습관과 저작근의 관련성에 대해서는 근전도 등을 이용한 연구가 이루어져왔으나, 안면표정근에 미치는 영향에 대해서는 연구된 바가 거의 없다. 그러므로 본 연구는 근육의 탄성도과 경직도를 정량적으로 평가할 수 있는 촉각센서(tactile sensor)를 이용하여 구강악습관이 저작근과 안면표정근에 미치는 영향을 평가하고자 하였다. 건강하고 건전한 치열을 가지고 있으며 Class I 교합관계의 정상골격인 지원자10명(20대 남성)을 연구대상으로 선택하여 촉각센서(Venustron II, Axiom Co, 일본)를 이용하여 이완 상태와 편측 이악물기(피검자가 선호하는 측의 제1대구치 부위에서 교합측정기를 50Kg force의 힘으로 깨문 상태), 턱내밀기(전치 상하절단연이 만나는 위치까지 턱을 내민 상태), 입술힘주기(치아는 닿지 않는 상태에서 입술만 꼭 다문 상태) 상태에서 저작근과 안면표정근의 경직도와 탄성도를 측정하였다. 측정근육은 측두근 전부, 교근(이상 저작근), 전두근, 하안륜근, 대관골근, 상 하 구륜근, 이근(이상 안면표정근)이었다. 통계처리를 위해 paired t-test, correlation coefficients, ANOVA 및 multiple comparison t-tests을 사용하였다. 편측 이악물기를 할 때 측정한 모든 근육에서 경직도와 탄성도는 좌우 차이를 보이지 않고 높은 상관관계를 보였다. 교근은 편측 이악물기 뿐만 아니라 턱내밀기, 입술힘주기의 시행된 모든 구강악습관에 의해 경직도가 증가하고 탄성도는 감소하였다(p<0.05). 측두근과 대관골근은 편측 이악물기의 영향을 받았으며, 상 하구륜근 및 이근의 경직도와 탄성도는 입술힘주기에 의해 크게 변화하였다(p<0.05). 본 연구의 결과는 편측 이악물기, 턱내밀기, 입술힘주기 같은 구강악습관은 저작근뿐만 아니라 안면표정근, 특히 구강주위근육에도 영향을 준다는 것을 보여준다.
