Cystic lesion of the jaw are frequently encountered clinically. Although they rarely lead to development of tumors, they can result in resorption of the jaw bone or asymmetry of the face may occur. The purpose of this study is to find the clinical and histopathological pattern of cysts and to help better understanding for the diagnosis and treatment of jaw cysts. The hospital chart, out-patient chart, panorama X-ray, histopathological report and operation report of 246 patients were reviewed who had been diagnosed as cyst. Sex distribution, age distribution, classification, anatomic distribution, clinical sign & symptoms, treatment, post-operation complications, recurrence rate were studied. Then significant difference between the diameter of cyst with bone graft and none-bone graft was calculated with SAS program. The results were as follows. 1. Among the total patient of 246 cases, male were 163 case(67.0%), and female were 83 case(37.0%), male predominated by the ratio of 1.98. 2. By age group, the 20's accounted for the largest proportion of the cases(27.2%) and the 30' accounted for the 2nd largest proportion of the case(19.5%). 3. Radicular cyst and dentigerous cyst were most common cysts, irrespective of 166 case(67.5%) and 62 case(25.2%). 4. Clinical sign & symptoms were swelling(167case), pain(85case), pus discharge(53case), teeth discoloration(28case), indicating that most complaints were related to inflammation and facial asymmetry. 4.9% of the total cases were discovered accidentally. 5. The primary site of cysts were maxillary anterior area(43.9%), the others were, in descending order, mandibular posterior area(25.6%), maxillary posterior area(14.6%). 6. Enucleation with endodontic treatment was a main treatment method(133 case, 54.1%) and 38 cases(15.4%) were enucleation with extraction, and 37 cases(15.0%) were only enucleation, and 21 cases(8.5%) were enucleation with bone graft. 7. The average diameter of cysts with bone graft was significally greater than with non-bone graft(p<0.05). 8. Post-operation complications occurred in 10 case(4.1%), all of this were due to secondary infection.

1. In oriental medicine, the case of sinusitis can be explained, not only external invasion such as PUNG HAN(wind-cold), PUNG YUL(wind-hot), SHUP YUL(damp-heat), but also functional disorder of internal organ such as spleen(脾), lung(肺), kidney(腎) The western medicine classified the cause of sinusitis as two factors. That is bacterial infection factor-Haemophilus influenza, streptococcus pyogeues, streptococcus pneumonia- and viral infection factor-Rhinovirus, parainfluenza, Echo28, Coxsacki21, Sinusitis is complicated to allergic rhinitis, chronic otitis media purulent, chronic tonsilitis, sinubronchitis. On the condition of nasal septum deformity, turbinates deformity, nasal septum deviation, sinusitis can be developed. the predisposing factors of sinusitis is swimming, air pollution, malnutrition, shortage of immunity.2. According to survey, sinusitis occurred that children from 4 to 12 years old and from 5 to 7 years old occupied 70% 3. From the past history data, they experienced chronic tonsillar hypertropy(20%), otitis media, atopic dermatitis, allergic rhinitis, bronchial asthma, pneumonia, bronchiolitis, chronic sore throat, urticaria, milk allergy in sequence. 4. the symptoms of sinusitis is nasal obstruction, postnasal dripping, purulunt(yellow)or white discharge, cough, nose bleeding in sequence. nasal obstruction take the portion of 95%, postnasal dripping 65%, night time or early morning cough 60%. 5. The suffering period of sinusitis is 6 month minimum, 4 years maximum, most cases are included in a year. The suffering period of children was shorter than adult. 6. Diagnosis depend on inspection of nasal cavity, postnasal dripping, X-ray finding. 75% of patient(15case) showed both maxillary sinusitis, 25%(5cases) showed left or right maxillary sinusitis. 7. Treatment of oriental medicine, consist of Herb-medicine, acupuncture and exposing of Lazer beam. Kamihyunggyeyungyotang(加味荊芥蓮翹湯) is administered mainly as the medical therapy, Kamigwaghyangjeungkisan(加味藿香正氣散) Kimizwakwieum(加味左歸飮), Kamihyangsosan(加味香蘇散) is administered for a additional symptoms which occurred by influenza recurrence. Kamijeonxibackchulsan(加味錢氏白朮散) is administered to treat gastro-intestine trouble patients who have sinusitis. 8. The period of treatment is varied with patient conditions and X-ray finding. The minimal period is 35days, maximal period is 202days. So it took about 86days in average and about 50% of patient(10cases) is recovered in one or two month.

Vallecular cyst is an uncommon but potentially dangerous condition causing stridor and has been associated with sudden airway obstruction resulting in death due to its anatomical location in neonates. It may also present with various degrees of feeding problems resulting in failure to thrive. When a vallecular cyst is suspected clinically, endoscopic laryngoscopy is necessary to visualize it. Other conditions leading to neonatal stridor such as laryngomalacia and other laryngotracheal abnormalities should be ruled out. Marsupialization with a $CO_2$ laser is the most effective and safest treatment to prevent recurrence. We report a case of a 1-month-old male infant with a vallecular cyst synchronous with gastroesophageal reflux, and failure to thrive. He was referred to our hospital because of hoarseness, inspiratory stridor, feeding-cyanosis, chest retraction and failure to thrive. Diagnostic workup revealed a cyst at the tongue base, suggesting a vallecular cyst. The cyst was removed by laryngomicrosurgery with $CO_2$ laser. After the surgery, the symptoms improved and the body weight increased steadily. We report a successfully treated case of neonatal vallecular cyst with symptoms of upper respiratory obstruction, gastroesophageal reflux, and failure to thrive.

Purpose: Frey's syndrome is a common complication after parotid surgery and characterized by gustatory sweating and flushing in the periauricular area during meals. Although a variety of methods have been proposed to prevent this postoperative problem but they have been unsatisfactory. In this article, therefore, botulinum toxin A was used to treat nine patients with Frey's syndrome and its duration effect after injection was investigated. Methods: Nine patients became the object of study about the effect of botulinum toxins as treatment of Frey's syndrome. Age of patients ranged from 25 to 78 years (mean, 43.7 years). Six of nine patients had both symptoms of gustatory sweating and flushing. And the others had only gustatory sweating symptom. Using Minor starch iodine test, the affected skin area was detected, and it was marked by $1cm^2$ sized grid appearance. After application of EMLA cream on the gustatory sweating area, botulinum toxin A was injected intracutaneously into the affected skin area ($2.5U/cm^2$). Patients were followed up from six to fifteen months (mean, about 12 months) and asked about improvement of their symptoms. Results: The treatement with botulinum toxin A took effective within two days after injection. Six months after injection, gustatory sweating disappeared completely in all patients, and five of six patients who had gustatory flushing improved in their symptom. Last follow-up, no patients complained of recurrent gustatory sweating and flushing except one. One patient, seven months after initial injection, was retreated with botulinum toxin A because of recurrence, and the result was successful. The duration of the effect after botulinum toxin A treatment was ranged from seven to thirteen months. One patient in our series experienced the upper eyelid weakness as adverse effect, but it improved spontaneously. Conclusion: Local injection of botulinum toxin A is an effective, safe and long - lasting method for treatment of Frey's syndrome. Hereafter, however, additional study will be required to evaluate the duration effect of botulinum toxin A according to frequency in use and dosage.

From June 1989 to May 1994, 23 patients with myasthenia gravis underwent thymectomy in the Department of Thoracic Surgery, Asan Medical Center. For the evaluation of the effect of thymectomy, clinical analysis including age and sex distribution, preoperative disease severity, duration of the symptoms, thymic pathology, and postoperative clinical improvement was performed. The mean follow-up period was 15 mon hs(range : 5∼60mon1hs). The effectiveness of thymectomy according to the postoperative symptoms and drug dose was graded as follow : a) complete remission in 5 cases (21.7%), b) clinical improvement with dose reduction in II cases (47.9%), c) clinical improvement without dose reduction in 3 cases(13.0%), 4) unchanged in 2 cases (8.8%), e) early death in 1 case(4.3%) and f) recurrence in 1 case(4.3%). According to the preoperative disease stage by Modified Osserman classification, 6(66.7%) of the 9 patients in stage I and 13 (92.9%) of 14 patients in stage II were clinically improved after thymectomy. although there was no significant statistical differences between these two groups (p> 0.05). According to the thymic pathology, 4 (100%) of 4 cases with normal thymus were clinically improved. Ten (90.9%) of 11 cases with thymic hyperplasia and 5 (62.5%) of 8 cases with thymoma were clinically improved, but there was no significant statistical differences in these three groups (p> 0.05 . The thymectomy resulted in dramatic clinical improvement in 19 (82.5%) out of 23 patients. According to the preoperative disease stage by Modified Osserman classification or the thymic pathology, there was no significant statistical differeneces in the effect of thyinectomy (p> 0.05).

Objective : Meralgia paresthetica (MP) is a syndrome of pain and/or dysesthesia in the anterolateral thigh that is caused by an entrapment of the lateral femoral cutaneous nerve (LFCN) at its pelvic exit. Despite early accounts of MP, there is still no consensus concerning the effectiveness of neurolysis or transaction treatments in the long-term relief for medically refractory patients with MP. We retrospectively analyzed available long-term results of LFCN neurolysis for medically refractory MP in an effort to clarify this issue. Methods : During the last 7 years, 11 patients who had neurolysis for MP were enrolled in this study. Nerve entrapment was confirmed preoperatively by electrophysiological studies or a positive response to local anesthetic injection. Decompression of the LFCN was performed at the level of the iliac fascia, inguinal ligament, and fascia of the thigh distally. The outcome of surgery was assessed 8 weeks after the procedure followed at regular intervals if symptoms persisted. Results : Twelve decompression procedures were performed in 11 patients over a 7-year period. The average duration of symptoms was 8.5 months (range, 4-15 months). The average follow-up period was 33 months (range, 12-60 months). Complete and partial symptom improvement were noted in nine (81.8%) and two (18.2%) cases, respectively. No recurrence was reported. Conclusion : Neurolysis of the LFCN can provide adequate pain relief with minimal complications for medically refractory MP. To achieve a good outcome in neurolysis for MP, an accurate diagnosis with careful examination and repeated blocks of the LFCN, along with electrodiagnosis seems to be essential. Possible variation in the course of the LFCN and thorough decompression along the course of the LFCN should be kept in mind in planning decompression surgery for MP.

Diagnosis of localized pigmented villonodular synovitis (PVNS) is difficult because of its rarity and indistinctive symptoms. This study presented 11 cases of localized PVNS of the knees, which were diagnosed and treated by arthroscopic technique. There were 6 males and 5 females between the age of 15 and 59 years (mean 34.6 years). The interval from the onset of symptoms to treatment ranged from 2 months to 3 years (average 29.9 months). All patients complained knee pain and 7 patients complained palpable mass. Four of the 11 patients had trauma history. The most common involved site was anteromedial synovium near the anterior horn of medial meniscus (5 patients). The remaining cases were identified on anterior fat pad (2 cases), suprapatellar pouch, posteromedial compartment, medial gutter and the anterior horn of the lateral meniscus, respectively. Nine cases had 1 mass and the remaining cases each had 2 or 3 masses. There was no evidence of recurrence during the follow-up period (average 29.9 months). Arthroseopy is effective in the diagnosis of localized PVNS with minimal morbidity and in the definitive treatment for PVNS.

Purpose: To evaluate long-term local control rate and toxicity in patients treated with external beam radiotherapy (EBRT) for pituitary adenomas. Materials and Methods: We retrospectively reviewed the medical records of 60 patients treated with EBRT for pituitary adenoma at Korea University Medical Center from 1996 and 2006. Thirty-five patients had hormone secreting tumors, 25 patients had non-secreting tumors. Fifty-seven patients had received postoperative radiotherapy (RT), and 3 had received RT alone. Median total dose was 54 Gy (range, 36 to 61.2 Gy). The definition of tumor progression were as follows: evidence of tumor progression on computed tomography or magnetic resonance imaging, worsening of clinical sign requiring additional operation or others, rising serum hormone level against a previously stable or falling value, and failure of controlling serum hormone level so that the hormone level had been far from optimal range until last follow-up. Age, sex, hormone secretion, tumor extension, tumor size, and radiation dose were analyzed for prognostic significance in tumor control. Results: Median follow-up was 5.7 years (range, 2 to 14.4 years). The 10-year actuarial local control rates for non-secreting and secreting adenomas were 96% and 66%, respectively. In univariate analysis, hormone secretion was significant prognostic factor (p = 0.042) and cavernous sinus extension was marginally significant factor (p = 0.054) for adverse local control. All other factors were not significant. In multivariate analysis, hormone secretion and gender were significant. Fifty-three patients had mass-effect symptoms (headache, dizziness, visual disturbance, hypopituitarism, loss of consciousness, and cranial nerve palsy). A total of 17 of 23 patients with headache and 27 of 34 patients with visual impairment were improved. Twenty-seven patients experienced symptoms of endocrine hypersecretion (galactorrhea, amenorrhea, irregular menstruation, decreased libido, gynecomastia, acromegaly, and Cushing's disease). Amenorrhea was abated in 7 of 10 patients, galactorrhea in 8 of 8 patients, acromegaly in 7 of 11 patients, Cushing's disease in 4 of 4 patients. Long-term complication was observed in 4 patients; 3 patients with cerebrovascular accident, 1 patient developed dementia. Of these patients, 3 of 4 received more than 60 Gy of irradiation. Conclusion: EBRT is highly effective in preventing recurrence and reducing mass effect of non-secreting adenoma. Effort to improve tumor control of secreting adenoma is required. Careful long-term follow-up is required when relatively high dose is applied. Modern radiosurgery or proton RT may be options to decrease late complications.

Oral lichen planus(OLP) is a chronic inflammatory disease with cell-mediated immune responses, but the exact cause is unknown. The treatment aim of OLP is not complete cure but to alleviate symptoms. In this study, two kinds of corticosteroid gargling solutions used for comparing the effects. From 2002 to 2010, 180 patients diagnosed with oral lichen planus and received topical steroid therapy in the Pusan National University Dental Hospital. Each of two types of solution contained dexamethasone (dexamethasone disodium phosphate) and prednisolone ($solondo^{(R)}$). A period of relief of symptoms and recurrence was recorded. The group using solution containing dexamethasone(dexa gargle) was prescribed to 33 patients(25 female, 8 male) and another group containing prednisolone (solon gargle) included 147 patients (114 female, 33 male). The effect of dexa gargle seemed faster than the solon gargle. There was no significant difference for recurrent rate between the groups using dexa and solon gargle.

Cerebral palsy(CP) is one of the most common motor disease, due to brain injury during fetal and neonatal development which results in neuromotor paralysis and associated neuromuscular symptoms. Features of CP include motor disability due to the lack of muscle control, often accompanied by sensory disorders, mental retardation, speech disorders, hearing loss, epilepsy, behavior disorders, etc. There are increasing chances of treatment of dental patients with cerebral palsy, as the occurrence of CP is increasing with the decrease in infant mortality and an increase in immature birth and premature birth and also, there is a trend to pursue of higher quality of life. Reports on the relationship between CP and maxillofacial deformity are uncommon, but it is well known that the unbalance and discontrol of the facial muscles, lip, tongue and the jaws leads to malocclusion and temporomandibular joint disorders, and statistics show that class 2 relationship of the jaws and open bite is frequently reported. However, it is difficult to perform maxillofacial deformity treatment, which consists of orthodontic treatment, maxillofacial surgery and muscle adaptation training, due to difficulties in communication and problems of muscle adaptation caused by difficulties in motor control which leads to a high recurrence rate. This case report is to trearment of maxillofacial deformity in CP patient. A 26 year old female patient came to the department with the chief complaint of prognathism of the mandible and facial asymmetry. According to the past medical history, she was diagnosed as cerebral palsy 1 week after birth, classified as GMFC, classII accompanied with left side torticollis. The patient's intelligence was moderate, and there were no serious problems in communication. For two years time, the patient underwent lingual frenectomy, pre-operation orthodontic treatment and then bimaxillary orthognathic surgery to treat mandibular prognathism and facial asymmetry followed by rehabilitatory exercise of facial muscle. After 6 months of follow up, there was a good result. This is to report to the typical signs and symptoms of DFD in CP patient and the limitation of the usual method of the treatment of DFD in CP patient with literature review.
