Wolff-Hirschorn syndrome is a condition that is caused by a deletion of genetic material near the end of the short (p) arm of chromosome 4. The major features of this disorder include a characteristic facial appearance, delayed growth and development, intellectual disability, and seizures. A 9-year-old girl was brought to the clinic with a chief complaint of dental examination. The child was diagnosed as WHS at Samsung medical center. The child was under Sodium valproate, Atrovastatin medication for epilepsy, hyperlipidemia and had a history of heart surgery. So prophylactic antibiotics were recommended. The child was mentally retarded and had seizure so it was difficult to manage her behavior effectively. Thus dental treatment was carried out under general anesthesia. For prompt sedation induction we used 8% sevoflurane shortly. This report presents the case of a 9-year-old girl with WHS, who has received treatment for extensive caries under general anesthesia.

Nasopharyngeal cancer is malignant tumor of nasopharyngeal area that is characterized of lymphadenopathy, pain, otitis media, hearing loss and cranial nerve palsy and may present symptoms similar to temporomandibular disorder such as facial pain and trismus. In this case, the patient with symptoms similar to temporomandibular disorder after surgery for otitis media presented with facial paresthesia and masticatory muscle weakness. Examinaion of trigemimal nerve was shown sensory and motor abnormaility. The patient was referred to a neurologist. Nasopharyngeal cancer was suspected on computed tomography and magnetic resonance imaging and was confirmed by biopsy. If the patient presenting with paresthesia and muscle weakness the cranial nerve examination should be performed regardless of typical temporomandibular disorder symptom. The neurologic symptom can be caused by neoplasm such as brain tumor and nasopharyngeal cancer. Nasopharyngeal cancer on rosenmuller fossa can develop otitis media. Therefore, the patient with otitis media history should be consulted to otorhinolaryngologist to examin the nasopharyngeal area.

Anaphylactic reactions to anesthetic drugs could potentially produce life-threatening immune-mediated crisis. Most published reports are associated with neuromuscular blockers and anaphylactic reactions to inhalation anesthetics are rare. A 25-year-old male patient with no significant medical history and no previous abnormal drug reaction was scheduled for orthognathic surgery under general anesthesia. After uneventful anesthetic induction and nasotracheal intubation, generalized urticaria and erythema were detected during the maintenance period with $O_2-N_2O$-enflurane. No severe changes of vital signs and no ventilation problem were accompanied. The operation was cancelled and the cutaneous lesions were faded away during the recovery with 100% $O_2$. The skin-prick and intradermal tests showed that he was hypersensitive to all halogenated inhalation anesthetics including enflurane and not to intravenous anesthetics and neuromuscular blockers. The re-operation was safely carried out under intravenous anesthesia with propofol-fentanyl-vecuronium. We report this case of intraoperative anaphylactic reaction to enflurane with literature review.

Purpose : To evaluate position of the mandibular condyle within articular fossa in an asymptomatic population radiographically by a cone beam computed tomography. Materials and Methods : Cone beam computed tomography of 60 temporomandibular joints was performed on 15 males and 15 females with no history of any temporomandibular disorders, or any other orthodontic or prosthodontic treatments. Position of mandibular condyle within articular fossa at centric occlusion was evaluated. A statistical evaluation was done using a SPSS. Results : In the sagittal views, mandibular condyle within articular fossa was posteriorly located at medial and central sections. In the coronal views, mandibular condyle within articular fossa was laterally located at central section. Mandibular condyles in the right and left sides were showed asymmetric positional relationship at medial, central, and lateral sections. Conclusion : Mandibular condyle within articular fossa in an asymptomatic population was observed nonconcentric position in the sagittal and coronal views.

Purpose: The presented study aims to evaluate the effects of osteoporosis on dental implants by analyzing a 12-year cumulative survival rate of implants placed in patients with osteoporosis. Methods: 37 patients with history of osteoporosis were selected from a pool of dental implant patients treated at the Department of Periodontology in Yonsei University Hospital between 1993 and 2007. The cumulative survival rate is quantified using data collected from 164 placed implants in the selected 37 patients. Results: 3 out of the 164 implants failed and the cumulative survival rate was observed at 95.1%. The survival rates of the implants according to patients' age were 97.41% (<60) and 100% ($60\leq$). The lower survival rate was directly proportional to younger age, and this relationship is statistically significant (P<0.05). The survival rates of implants according to diagnostic criteria were 95.45% (osteopenia) and 98.59% (osteoporosis; 2 out of 142 implants placed in osteoporosis patients failed). The difference in the two survival rates is statistically significant (P<0.05). The survival rates according to the region of implants do not have statistically significant difference. The survival rates according to the different length and diameter of the implants do not have statistically significant difference. The survival rates of implants accompanied and not accompanied by bone augmentation were 92.11% and 100%, respectively. The difference in the two survival rates is statistically significant (P<0.05). The survival rates of implants placed in patients with and without history of medication for osteoporosis treatment are 96.67% and 99.04%, respectively. The difference in the two survival rates is statistically significant (P<0.05). Conclusions: A high cumulative survival rate of dental implants, similar to one found in non-osteoporosis patients, is observed in osteoporosis patients, indicating the possibility that placing dental implants on patients with osteoporosis can be considered with high treatment predictability.

King Gojong was the twenty-sixth King in the Choseon Dynasty. He took the throne when he was only 12 years old and had to set up regency for 10 years. During his period, situations were worsened in both domestic and foreign affairs. In the end, after 3 years from abdication of the throne, the Choseon Dynasty was overthrown in compliance with a coercion by Japanese empire. He died in 68 years old. We can assume that his inveterate disease are weakness of the spleen and the stomach. In addition, he suffered from a boil, a cold, dermatosis, eye disease, an external wound, dentistry disease, arthritis, etc. The official cause of his death was cerebral hemorrhage. But we assume that the possibility of poison murdering is high.

In this study, we present the surgical treatment of obstructive sleep apnea in a child with Treacher Collins syndrome. A 10-year-old girl with a past history of Treacher Collins syndrome presented to our clinic with her parents for respiratory distress and insomnia. The patient was referred to a sleep laboratory where she was diagnosed with obstructive sleep apnea, which was a consequence of her Treacher Collins syndrome. The patient underwent mandibular distraction osteogenesis under general anesthesia. The mandible was expanded by 15 mm using internal bilateral distractors. After distraction osteogenesis, the patient's respiratory problems resolved, and she was able to sleep comfortably. Distraction osteogenesis was an effective method of advancing the mandible, increasing the upper airway space and ultimately preventing obstructive sleep apnea syndrome in patients with Treacher Collins syndrome.

Familial gigantiform cementoma is a rare fibre-cemento-osseous disease of the jaws which appears to be transmitted as an autosomal dominant trait with variable expressivity of the phenotype. A 7-year-old girl visited DKUDH complaining of the painless facial deformity. Clinically, significant facio-lingual expansion was observed at the left maxilla, left mandibular body and symphysis portion. Malposition of lower anterior teeth was found. Panoramic radiograph and CT scan showed the extensive expansile mixed lesion at maxilla and mandible. Bone scan revealed hot spot at the maxilla and left side of mandible. Histologic examination revealed moderately dense fibrous connective tissue with scattered masses resembling cementum. The patient's mother had a history of the mandibular resection due to benign tumor. Her younger brother had buccal expansion of right mandible. We report our finding of a family that has exhibited clinical, radiographic and histologic findings consistent with the familial gigantiform cementoma.

McCune-Albright syndrome (MAS) is a disease with clinical features such as fibrous dysplasia in which normal bone tissue is replaced with abnormal fibrous tissue, abnormalities in the endocrine system, and cafe-au-lait spots on the skin. Although MAS patients are generally known to have reduced bone healing ability, postoperative healing after invasive surgical extraction is still not clearly known due to its relatively rare occurrence. In this report, a 25-year-old female patient, who had been diagnosed with MAS and had a history of abnormal bone healing after fractures of her extremities, underwent surgical extraction of the mandibular third molar with surrounding bone removal. Postoperatively, the patient showed favorable soft tissue and bone healing at the surgical site without abnormal findings such as newly developed fibro-osseous lesions, postoperative infection, or osteomyelitis.
