Objective : Miller-Fisher syndrome(MFS) is a type of acute inflammatory polyneuropathy, a disease characterized by abnormal muscle coordination, absence of tendon reflexes, and paralysis of the eye muscle. This study is to report a case of delayed facial palsy and dizziness in Miller-Fisher syndrome, treated with traditional Korean medicine. Methods : A 57-year-old male was diagnosed with Miller-Fisher syndrome accompanied by neurological symptoms such as right facial palsy and dizziness. He received traditional Korean medicine treatment such as acupuncture(including pharmacopuncture, needle embedding therapy, electroacupuncture) and herbal medicine for 17 days. Results : Each neurological symptoms were improved after traditional Korean medicine. In case of facial palsy, House Brackmann Grading System was reduced form grade 3 to grade 2, and Sunnybrook Scale was improved from 39 to 55. Also, other symptoms such as dizziness and headache was also improved. Conclusions : This case report suggests that traditional Korean medicine may have a role in treating neurological symptoms such as facial palsy and dizziness in patient diagnosed with Miller-Fisher syndrome.

Background: We have devised a novel surgical method, termed as temporalis muscle tendonperiosteum (T-P) compound surgical method, by modifying pre-existing techniques. Our method is characterized by elevation of temporalis muscle tendon and the periosteum of the mandibular ramus as a single compound. Here, we describe the concept and clinical outcomes of our method. Methods: We conducted both a cadaveric study and a clinical study. First, we used four human cadavers (two males and two females) to confirm the anatomy of the temporalis muscle tendon and availability of sufficient length extension through the elevation of the T-P compound. Moreover, we obtained measurements of the mouth angle and the philtrum angle from a total of six patients (two males and four females) and compared them between preoperatively and postoperatively. Results: The mean length of the periosteal portion was measured as 2.43± 0.15 cm (range, 2.2-2.6 cm). There was an improvement in the mouth angle postoperatively as compared with preoperatively (7.2°± 3.0° vs. 14.5°± 4.7°, respectively). Moreover, there was also an improvement in the philtrum angle postoperatively as compared with preoperatively (7.2°± 3.4° vs. 17.2°± 6.5°, respectively). Conclusion: Our method is a simple, minimally-invasive modality that is effective in achieving good clinical outcomes. Its advantages include an ability to achieve a firm extension of the temporalis muscle tendon as well as a lack of requirement for a donor site that may cause complications.

Schwannoma is a slow-growing, well-demarcated, benign soft tissue tumor of the peripheral nerve sheath. It commonly develops in the head and neck region, usually in the parapharyngeal space. In this case, a 42-year-old woman visited the outpatient department to manage a painless mass on her left cheek. She had no history of concern and no neurological symptoms were observed. In the enhanced computed tomography scan, a 2.8×2.8×1.8 cm, heterogeneously enhanced tumor was detected in the left masseter muscle. A tumor resection under general anesthesia was planned. For the resection, a facelift incision was chosen; branches of the facial nerve were identified and retrogradely dissected. A well-marginated, yellowish, solid mass was found in the left masseter muscle. The mass was excised and given a histopathological diagnosis of schwannoma. A definite diagnosis of schwannoma, originating in the masseter muscle, is difficult to arrive at with radiographic findings alone; it is often misdiagnosed as intramuscular hemangioma. Histopathological examinations, including fine-needle aspiration or histological biopsy after surgery, are necessary. Using a facelift incision with retrograde facial nerve dissection, tumor resection in an intramasseteric lesion can be performed efficiently, without nerve damage, or leaving conspicuous scars on the face.

Purpose: Corrugator supercilii muscle pulls eyebrow to inferomedial direction and produces the vertical component of the glabellar line formation. Current techniques for eliminating of glabellar frown include direct resection of corrugators and botulinum toxin injection. Muscle resection in endoscopic face lift procedure is relatively complex and has many disadvantages ranging from possible nerve injury, postoperative edema, pain and a long recovery period. The Botox treatment on the other hand is much more simple in technique but has a short duration of action. The authors have attempted new ways of finding improved treatment of the glabellar frown by selectively blocking of motor nerves innervating the corrugator supercili muscle by using radiofrequency ablation technique. Methods: A total of 80 patients were recruited in our study during the period between Feb. 2007 to June 2008. A probe was introduced from the supraorbital ridge and advanced to the corrugator supercilii muscle. Nerve stimulator was then used to locate the nerve innervating the corrugator and radiofrequency ablation of the nerve was done. Results: In all patients, there were marked improvement in glabellar frown after treatment. There were no reported cases of any relapses during the follow up period. No complication was noted such as facial nerve injury. No patient complained of any adverse symptoms other than slight discomfort due to swelling of the operation site. Conclusion: The treatment of glabellar frown lines using selective nerve block with radiofrequency ablation was not only less invasive but also excellent in surgical outcomes.

Osteochondroma is the one of the most benign tumors of the axial skeleton, but is rarely found in the facial bones. Typical facial features of condylar osteochondroma include striking facial asymmetry, malocclusion with openbite on the affected side, and prognathic deviation of the chin and crossbite to the contralateral side. In this case, twenty four year-old female showed facial asymmetry, chin deviation, openbite on the affected side but have no symptoms of pain or dysfunction. Concomitantly she had maxillary occlusal cant and hemimandibular hypertrophy. Panoramic radiograph showed radiopaque mass on right mandibular condyle extended along the lateral pterygoid muscle. Computed tomogram demonstrated enlarged condylar head and bony spur on posteromedial side of condyle and 99Tc bone scintigraphy showed a focal hot image. These findings were correspond with osteochondroma. The lesion was treated with condylectomy and residual facial asymmetry was corrected with 2-jaw orthognathic surgery. Herein, we report a case of osteochondroma of the mandibular condyle and accompanying facial asymmetry.

Schwannoma is a benign tumor rarely found in the head and neck and much less commonly found in the intraparotid facial nerve. It is a slow-growing encapsulated tumor originating from the Schwann cells or axonal nerve sheath. It can occur anywhere along the course of the facial nerve. Patients may present with symptoms of facial palsy, but the most common presenting symptom is an asymptomatic swelling. Diagnosis is usually difficult before surgical removal and histopathological examination. We report a rare case of intraparotid facial nerve schwannoma in a 57-year-old female who had sustained a mass of the right preauricular area for 3 years. She reported no pain or facial muscle weakness. Enhanced computed tomography findings revealed the impression of pleomorphic adenoma. However, intraoperative gross findings were not characteristic of pleomorphic adenoma, and a frozen biopsy was performed resulting in the impression of a nerve sheath tumor. We performed an extracapsular surgical excision without parotidectomy. Permanent histopathology and immunohistochemistry reports diagnosed the mass as schwannoma. There were no complications including facial palsy after surgery. No recurrence was found at 6 months after surgery.

This study aims to demonstrate the effectiveness of facial chuna manual therapy in treating the sequelae of Bell's palsy. Four patients were treated with facial chuna manual therapy once a week for 4 weeks, consisting of facial muscle massage, acupoint pressure, contracture chuna, and synkinesis chuna. The changes in symptoms (contracture and sysnkinesis) were measured using the Sunnybrook Facial Grading Scale (SFGS), Synkinesis Assessment Questionnaire (SAQ), Facial Disability Index (FDI), Contracture/Synkinesis scale using a facial scanning system, Numeric Rating scale (NRS) for synkinesis or contracture, and Was It Worth It questionnaire. After treatments, SFGS, Contracture/Synkinesis scale, and NRS for synkinesis or contracture showed significant improvements. SFGS increased in three cases from 39~76 to 52~85 score. SAQ decreased in two cases from 53.33~57.78 to 40.00~55.56. FDI increased in three cases from 120~128 to 138~145. These results suggest that Korean medicine treatment, including facial chuna manual therapy can be effective in improving the sequelae of Bell's palsy.

A patient with sequelae of peripheral facial nerve palsy (FNP) was mainly treated with facial chuna manual therapy (FCMT) for over 6 months. The patient was diagnosed with hemophilia B and C, so invasive treatments, such as acupuncture and pharmacopuncture, were precluded. The facial nerve grading system 2.0 (FNGS) and the House-Brackmann Grading Scale (HBGS), Peitersen, Murata, Mehta, and numeric rating scale (NRS) systems were used to measure treatment effectiveness. Each scale showed improvement: FNGS, 3 to 2; HBGS, 3 to 2; Peitersen scale, 2 to 1; Murata scale, 9 to 4; Mehta scale, 14 to 1; and NRS, 8.5 to 2.5. An overall improvement was evident in facial muscle strength, particularly in synkinesis. If acupuncture and pharmacopuncture are unavailable, FCMT alone may be effective in treating FNP sequelae.
