Objective : The accurate anatomy of the facial nerve is essential for successful surgical outcome. The purpose of the present study is to know such information on the facial nerve from a series of specimens. Methods : This study is based on cadaveric dissection of 41 Korean fetus and stillborn infant and describes anatomical variations of the peripheral branches of the facial nerve that pose a importance in a number of neruosurgical procedure. Results : The branching patterns were classified into six types according to modified Davis classification : the frequencies of occurrence were : type I, 4.9%; type II, 24.4%; type III, 34.1%; type IV, 19.5%; type V, 12.2%; and type VI, 4.9%. Types II, III and IV together accounted for almost 80% of the specimens. Conclusion : Compared to previous adult and western stillborn fetus cadaveric studies, there was no significant difference in the percentage of the types between the subjects in the present study, similar pattern and anatomic distribution.

BSSRO (bilateral sagittal split ramus osteotomy) is frequently performed to correct dentofacial deformity and malocclusion. Among its complications the incidence of post-operative facial nerve palsy is very rare, but it is one of the most serious complications. The case of a 21-year-old male patient who underwent facial nerve palsy after BSSRO is described. After surgical intervention and conservative therapy, the patient recovered his facial nerve function successfully.

Facial nerve palsy is not an uncommon disease encountered at the department of otolaryngology or pain clinic. It usually occurs following viral infection(Bell's palsy, BP). However, it is rare to develop bilaterally, and that not simultaneously. We experienced a rare case of bilateral facial nerve palsy. Patient first experienced left side paralysis, then right side paralysis approximately two months later. We treated the patient with serial bilateral stellate ganglion blocks(SGB). When left side paralysis improved, we performed unilatertal SGB for right side paralysis. Patient was also treated with intermittent electro-acupuncture stimulations, to right side first, then left side. Four months of treatment provided good results. This may be the first case, in Korea, of facial nerve paralysis bilaterally within a certain interval, treated with serial SGB and electro-acupuncture stimulation. However, the etiology of this bilateral BP was not fully confirmed as being a cause of viral origin.

It is the aim of this study to determine the effects of facial denervation on physiological properties of facial muscles and facial bones in growing rabbits. Experimental animals of fifty two Oryctolagus cuniculus rabbits were employed. Unilateral dissection of facial nerve was carried out on twelve rabbits, bilateral dissection of facial nerve was made on another twelve rabbits and the other twenty rabbits were on unilateral dissection of facial nerve for the histochemical analyses. Six rabbits on the bilateral surgical sham operations and six rabbits of non-intervention served the control groups. EMG records of the orbicularis oris, buccinator and masseter muscles as well as lateral and dorsoventral cephalometric films were taken and analyzed at 0, 1, 2, 5 and 8 weeks respectively. The orbicularis oris, buccinator and masseter muscles of both sides were removed from the animals of the histochemistry group and muscle fibers were classified on the basis of histochemical staining for $\alpha$-GPD, NADH-D and myosin ATPase. EMG activities of orbicularis oris and buccinator muscles were vanished immediately after denervation. Recovery of activities were detected one week after denervation in buccinator and five weeks in orbicularis oris muscles. Histochemical properties of masseter muscles remained as fast glycolytic through the experimental period. Orbicularis oris muscle fibers showed the gradual diminution of size and ratio of the slow oxidative fibers accompanied with atrophy, phagocytosis and vacuolation as well as the augmentation of fast oxidative glycolytic fibers. The buccinator muscle manifested the augmentation of fast oxidative glycolytic fibers at five weeks of experiment. Visual changes in morphology of craniofacial area were not evident, however it variety of subtle changes were apparent from statistical analysis of cephalometric measurements. It is concluded facial nerve regulates the physiological properties of facial muscles and interrelation between the function of the facial muscles and changes of facial bones would be in some degrees.

Facial palsy is a general nerve disease which is occurred in a lateral incomplete or complete facial palsy. But it makes man restrict a social activity and so it is very important that we know the prognosis factors of a patient for medical care. We want to investigate the position and the patterns of the facial palsy according to sex and age. In this study, we performed the excitability test of the facial nerve on 103 patients (male 45 and female 58) which diagnosed as the Bell's palsy having an acute facial palsy, and the rate of the facial palsy was 42% (43 case) in right oculi and 58% (60 case) in left oculi. The facial palsy was appeared widely from young to elderly patients and especially, the rate of the facial palsy was high in age groups from 40 to 50.

Vestibular schwannoma (VS) usually present the widening of internal auditory canal (IAC), and these bony changes are typically limited to IAC, not extend to temporal bone. Temporal bone invasion by VS is extremely rare. We report 51-year-old man who revealed temporal bone destruction beyond IAC by unilateral VS. The bony destruction extended anteriorly to the carotid canal and inferiorly to the jugular foramen. On histopathologic examination, the tumor showed typical benign schwannoma and did not show any unusual vascularity or malignant feature. Facial nerve was severely compressed and distorted by tumor, which unevenly eroded temporal bone in surgical field. Vestibular schwannoma with atypical invasion of temporal bone can be successfully treated with combined translabyrinthine and lateral suboccipiral approach without facial nerve dysfunction. Early detection and careful dissection of facial nerve with intraoperative monitoring should be considered during operation due to severe adhesion and distortion of facial nerve by tumor and eroded temporal bone.

Background: Herpes Zoster Oticus, which can be caused from infection by Varicella-zoster virus, is known to be expected poor prognosis, since it has higher possibility of complete injury of facial nerve. Conservative therapy of the Western medicine is effective on the treatment for the herpes zoster and pain. However, its effectiveness on the facial verve palsy has not been proven. Objective : This study was performed to evaluate the treatment of oriental medicine and an analyze prognosis of the facial nerve palsy in Herpes Zoster Oticus. Methods : This retrospctive study was conducted to observe the clinical manifestation of Herpes Zoster Oticus, and the result of electrical diagnostic study on the patients with the facial nerve palsy in Herpes Zoster Oticus who were diagnosed and treated at the Department of Acupuncture & Moxibustion in Kyung Hee Oriental Medical Hospital. Results : 1. According to the six clinical types of Herpes Zoster Oticus, the patients in this study can be grouped as 7 cases of the type II, 2 cases of the type V, and one case of the type IV and the type VI. 2. The shorter the period from onset to the first visit to a hospital, the prognosis of facial nerve palsy in Herpes Zoster Oticus was the better. 3. According to the follow up study, the H-B grades of all cases were improved. 4. According to the follow up study, the result of electrical diagnostic study was improved. Conclusions : We found in our study that the treatment of oriental medicine, such as acupuncture, herbal medicine and aroma therapy, helps the recovery of facial nerve palsy in Herpes Zoster Oticus. The further clinical study about the more cases of facial nerve palsy in Herpes Zoster Oticus and comparative study between the group of oriental medicine and that of western medicine are needed.

Background Temporalis muscle transfer produces prompt surgical results with a one-stage operation in facial palsy patients. The orthodromic method is surgically simple, and the vector of muscle action is similar to the temporalis muscle action direction. This article describes transferring temporalis muscle insertion to reconstruct incomplete facial nerve palsy patients. Methods Between August 2009 and November 2011, 6 unilateral incomplete facial nerve palsy patients underwent surgery for orthodromic temporalis muscle transfer. A preauricular incision was performed to expose the mandibular coronoid process. Using a saw, the coronoid process was transected. Three strips of the fascia lata were anchored to the muscle of the nasolabial fold through subcutaneous tunneling. The tension of the strips was adjusted by observing the shape of the nasolabial fold. When optimal tension was achieved, the temporalis muscle was sutured to the strips. The surgical results were assessed by comparing pre- and postoperative photographs. Three independent observers evaluated the photographs. Results The symmetry of the mouth corner was improved in the resting state, and movement of the oral commissure was enhanced in facial animation after surgery. Conclusions The orthodromic transfer of temporalis muscle technique can produce prompt results by applying the natural temporalis muscle vector. This technique preserves residual facial nerve function in incomplete facial nerve palsy patients and produces satisfying cosmetic outcomes without malar muscle bulging, which often occurs in the turn-over technique.

Many surgeons have demonstrated the validity of sternocleidomastoid muscle flaps for the reconstruction of head and neck tumors. We present a case in which we used an island sternocleidomastoid muscle flap to reconstruct a cheek depression after excision of a malignant parotid tumor. A 44-year-old woman presented with a right malignant parotid tumor. We performed total resection of the parotid gland and facial nerve with the sural nerve and reconstructed the facial nerve and cheek depression with an island sternocleidomastoid muscle flap. The sternal head of the right sternocleidomastoid muscle was cut at the cranial and caudal segments to elevate it as an island flap. We used the superior thyroid artery as the sole pedicle for the island muscle flap. At 1 year and 3 months after the operation, the mimic muscles had gradually recovered and progressed without complications such as Frey syndrome, cervical motor dysfunction, or concave deformation of the neck and cheeks.
