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.

We experienced failed airway management in a patient who had partial mandibulectomy and reconstruction with free-flap. 40 year-old man (height: 164 cm, body weight: 59 kg) with malignant melanoma on #38 tooth area of mandibular body was scheduled for partial mandibulectomy and reconstruction with free flap. Approximately fifteen-hours after surgery, the patient was extubated without complication. Seven hours after extubation, we experienced respiratory failure andfailed airway managementdue to airway edema and neck. We failed orotracheal intubation with direct laryngoscopy andlaryngeal mask airway, thus we tried tracheostomy but the patient was hypoxic state for more than 30 minutes. The patient had got hypoxic brain damage in whole cerebral cortex and basal ganglia. We should have the policy of airway management of the patients who have massive oro-maxillo-facial surgery and all medical personnel who treat these patients should be educated the policy and airway management methods.

Objectives: This study aimed to investigate the efficacy of postoperative submucosal injection of hyaluronidase (HUD) for reducing sequelae and quality of life (QOL) after mandibular third molar (M3M) surgery. Materials and Methods: Participants with bilateral impacted M3M underwent surgical extraction with a split-mouth randomized controlled study design. M3M were removed by the same surgeon in 2 sessions, one a control and the other experimental. Submucosal injection of HUD was performed in the experimental session and submucosal injection of saline in the control session. Mouth opening, facial swelling, and pain intensity were measured before surgery, and then 2 and 7 days after surgery. The QOL of participants following surgery was evaluated by means of a patient-centered outcome questionnaire (PCOQ). Results: A total of 36 patients was included in the final data analysis. There was a significant reduction in the maximal mouth opening and postoperative pain in the experimental side at the 2 and 7 days after surgery (P<0.05), and a remarkable difference in facial swelling was reported on the experimental side 7 days after surgery (P<0.05). The PCOQ demonstrated that participants reported less pain and swelling on the experimental side. Conclusion: The present study provides clinical evidence that submucosal administration of HUD immediately after M3M surgery reduced postoperative discomfort and improved patients' QOL.

Objective : To prospectively compare facial pain outcomes for patients having either a repeat microvascular decompression (MVD) or percutaneous balloon compression (PBC) as their surgery for trigeminal neuralgia (TN) recurrence. Methods : Prospective cohort study of 110 patients with TN recurrence who had either redo MVD (n=68) or PBC (n=42) from July 2010 until September 2016. The mean follow-up was 45.6 months. Results : After redo MVD, 65 patients (95.6%) experienced immediate relief of pain. After PBC, 34 patients (81%) were immediately relieved of their neuralgia. After 1 month, the clinical effect of redo MVD was better than PBC (p<0.01). Patients who had redo MVD more commonly were pain free off medications (93.4% at 1 year, 78.2% at 4 years) compared with the PBC patients (85.1% at 1 year, 59.3% at 4 years). However, mean length of stay was longer (p>0.05). Patients after PBC who occurred developed herpes simplex (35.7%), facial numbness (76.2%), and annoying dysesthesia (21.4%) more frequently compared with patients after redo MVD who occurred developed herpes simplex (14.7%), facial numbness (8.8%), and hypoesthesia (5.9%) (p<0.05). The symptoms recurred respectively in 15 patients (22.1%) and 19 patients (45.2%) after redo MVD and PBC within the entire 6-year follow-up period. Conclusion : For the patients with TN recurrence, redo MVD was a more effective procedure than PBC. The cure rate and immediate relief of pain were better, and the incidence of complications was lower.

Background: Miller-Fisher syndrome (MFS) is characterized by the clinical triad of ophthalmoplegia, ataxia, and areflexia, and is considered a variant form of Guillain-Barre syndrome. Although some cases of delayed-onset facial palsy in MFS have been reported, the characteristics of this facial palsy are poorly described in the literature. Methods: Between 2007 and 2010, six patients with MFS were seen at our hospital. Delayed facial palsy, defined as a facial palsy that developed while the other symptoms of MFS began to improve following intravenous immunoglobulin treatment, was confirmed in four patients. The clinical and electrophysiological characteristics of delayed facial palsy in MFS, as observed in these patients, are described here. Results: Four patients with delayed-onset facial palsy were included. Delayed facial palsy developed 8-16 days after initial symptom onset (5-9 days after treatment). Unilateral facial palsy occurred in three patients and asymmetric facial diplegia in one patient. The House-Brackmann score of facial palsy was grade III in one patient, IV in two patients, and V in one patient. None of the patients complained of posterior auricular pain. Facial nerve conduction studies revealed normal amplitude in all four patients. The blink reflex showed abnormal prolongation in two patients and the absence of action potential formation in two patients. Facial palsy resolved completely in all four patients within 3 months. Conclusions: Delayed facial palsy is a frequent symptom in MFS and resolves completely without additional treatment. Thus, standard treatment and patient reassurance are sufficient in most cases.

Orofacial pain is a common complaint of patients that causes distress and compromises the quality of life. It has many etiologies including trauma, interventional procedures, nerve injury, varicella-zoster (shingles), tumor, and vascular and idiopathic factors. It has been demonstrated that the sympathetic nervous system is usually involved in various orofacial pain disorders such as postherpetic neuralgia, complex regional pain syndromes, and atypical facial pain. The stellate sympathetic ganglion innervates the head, neck, and upper extremity. In this review article, the effect of stellate ganglion block and its mechanism of action in orofacial pain disorders are discussed.

Objectives : This study was to observe clinical application of auto-microneedle therapy system (AMTS) in patients with peripheral facial paralysis. Methods : 27 peripheral facial paralysis patients were observed after taking AMTS at Facial Palsy Center, Kyung Hee University Oriental Medicine Hospital from March 1, 2011 to January 9, 2012. We assessed the symptoms of facial paralysis with Yanagihara unweighted grading system, Sunnybrook facial grading system(SBGS) and facial disability index(FDI), and observed adverse events and total safety of the treatment. Results : The scores of facial palsy scales increased after AMTS in Yanagihara grading system and Sunnybrook facial grading system. AMTS-related adverse events were mild pain(5.9%) and fatigue(3.5%), which needed no extra treatment. The total safety evaluation was between 'safe' and 'nearly safe' level. There were no other serious adverse events. In addition, patients were satisfied with subjective improvement including facial tingling and numbness. Conclusions : AMTS can be applied as an adjunctive treatment for patients with peripheral facial paralysis due to its safety and clinical usefulness. It is easier to stimulate wide skin area in a short time. Further clinical research is required to investigate the effectiveness of ATMS in a more rigorous RCTs.

Ankylosing spondylitis (AS) is a chronic inflammatory joint disorder characterized by sacroiliitis, spondylitis and enthesitis. Patients suffering from AS may also have extra-articular symptoms, such as uveitis, bowl disease, heart, lung, skin, bone and kidney involvement, but vary widely in severity and prevalence. Facial manifestation of AS include eye involvement and temporomandibular joint involvement. In this study, a case of an AS that mimicked dental pain was presented.
