The aim of this study was to evaluate the analgesic effects of Samultang by measuring the anti-inflammatory and antioxidative activities in formalin-induced orofacial pain. The anti-inflammatory and anti-oxidative effects were measured by western blot analysis for p38 MAPK(Mitogen-activated protein kinases), iNOS(induceble nitric oxide synthase) and NOX4(nicotinamide adenine dinucleotide phosphate4) in a rat's brain and medulla oblongata. Samultang significantly attenuated the increased formalin-induced nociceptive response and inhibited the p38 MAPK and iNOS that led to inflammatory pain. In addition, this study indicated that Samultang possess antioxidative effects through the blockade of NOX4. These findings suggest that Samultang plays an important role in the peripheral processing of inflammatory pain in the orofacial area.

Background: Facial hyperhidrosis patients have as much difficulty in personal relationships as the palmar and axillary hyperhidrosis patients. There have been no appropriate treatment, but recently, satisfactory results have been obtained through sympathetic blockade. Thoracoscopic thoracic sympathectomy for facial hyperhidrosis has been known to resect cervicothoracic (stellate) ganglion, but its inherent complications such as Horner syndrome have made the surgeons hesitant to use this method. We, through our experiences in treating palmar and axillary hyperhidrosis for the past 6 years, believed that T2 sympathicotomy would be enough for facial hyperhidrosis and have experimented and obtained satisfactory results. Material and Method: From June 1997 to May 1998, 38 consecutive patients underwent bilateral thoracoscopic T2 sympathicotomy with 2mm instruments at Seoul National University Hospital. Result: All patients were relieved of excessive sweating in their faces immediately after the operation. Postoperatively, 5 patients (13.2%) required insertion of chest tubes because 3 had incomplete reexpansion of the lung, and 2 had hemothorax from severe adhesion. Other complications related to the surgical procedures, such as Horner's syndrome, and brachial plexus injury, were not detected in any cases. The mean hospital stay was mean 1.7$\pm$0.9 days after surgery. Conclusion: T2 sympathetic ganglion is the appropriate resection site for facial hyperhidrosis, and complications such as Horner syndrome can be prevented by not cutting the stellate ganglion. In addition, it is possible to perform the operation by using a 2 mm thoracoscopic instrument, and may obtain much better results.

중안면부의 골절은 심미적으로나 기능적으로 많은 문제를 야기할 뿐아니라 두개부와 연관되어 뇌손상의 가능성을 가지므로 생명과 직접적인 연관을 갖는다고 할수 있다. 산업사회의 고도의 발달로 인하여 자동차의 보급이 증가하고 그에 따라 교통사고의 절대수가 증가하고 안면부 골절환자가 증가추세에 있다고 볼 수 있다. 때문에 구강악안면외과의사로서 중안면부의 골절에 관심을 기울여야 할 것으로 생각된다. 중안면부 골절 가운데 비골을 포함한 안와 근심벽의 쉽게 일어나며 골절에 포함된 해부학적 구조물들이 복잡하기 때문에 골절후에 기능적 이상이 쉽게 발생될 수 있다. 본 과에서 처치한 중안면 골절 환자중 비골을 포함한 안와 근심벽의 골절환자를 경험한 바 이에 보고하는 바이다.

혈관외피세포종(Malignant hemangiopericytoma)은 난원형의 혈관외피세포(pericyte)들로 구성된 매우 드문 혈관종의 일종으로 대개 사지 및 후복막에 발생되며, 안면부와 경부에도 약 25%가량의 발생율이 보고되어 있다. 성별 발생빈도의 차이는 없고 $20{\sim}50$대에서 호발하며, 종양은 대부분 서서히 성장하고 경계가 명확한 무통성의 고형 종괴로 나타난다. 악성과 양성의 구별은 조직학적 소견과 주변 조직으로의 침습, 원격전이 여부 등을 고려하여 판단하지만, 양성으로 진단된 경우에도 수년 내에 재발 및 원격전이가 나타나는 경우가 다수 보고되므로 악성과 양성의 감별이 매우 어렵고. 양성인 경우에도 악성 잠재성이 존재하는 것으로 알려졌다. 치료는 수술적 완전절제가 유일한 방법이나 절제가 불완전한 경우는 수술 후 외부 방사선 조사를 한다. 항암제 투여는 효과면에서 논란이 있지만, 원격전이나 수술과 방사선 치료가 실패한 경우 시행할 수 있다. 저자들은 최근 안면부에 발생한 악성 혈관외피세포종 환자 1예를 치험하였기에 보고하는 바이다.

The dentigerous cyst originates through alteration of the reduced enamel epithelium after the crown of the tooth has been completely formed, with accumulation of fluid between the reduced enamel epithelium and the tooth crown. The dentigerous or follicular cyst comprises about 20% of all dental cysts. It usually occurs between 20 and 30 years of age but is occasionally seen in children or in old people. The most common sites of this cyst are the mandibular third molar and maxillary cuspid areas, since these are the most commonly impacted teeth. Many of these cysts give no clinical symptoms until noticeable asymmetry of the face develops. Rarely it develops to an ameloblastoma, epidermoid carcinoma and mucoepidermoid carcinoma, so early removal leads to better result. Roentgenographic examination of the jaw involved by a dentigerous cyst will reveal a radiolucent area. Recently the authors have experienced a giant dentigerous cyst which produced the bony deformity of the maxillary and hard palate bone. The cyst was completely removed under the local anesthesia by Caldwell-Luc approach.

피지선종(sebaceous adenoma)은 피지선 분화를 보이는 신생물 중 가장 흔한 종양으로 피지선이 정상적으로 많이 분포하는 안면부, 두피부, 안검부 등에 주로 발생하나 안검에서는 비교적 드물게 발생한다. 피지선종은 피부부속기 종양 중 발생빈도가 아주 낮으며 안면부 중에도 피지선이 많이 분포하는 비부와 협부에 주로 발생하며 종괴 형성으로 인한 이물감이나 소양감, 출혈, 궤양형성등의 증상을 동반한다. Shields 등의 보고에 의하면 내안누구에 발생한 신생물 57예중에서 피지선종은 2예만이 존재할 정도로 극히 드물다고 하였다. Font와 Rishi도 피지선종의 안검 발생에 대하여 상안검과 하안검은 각각 같은 빈도로 발생한다고 하였으며 내안각 피지선종은 단 1예만을 보고하였다. 이에 저자들은 내안누구의 피지선에서 발생한 피지선종을 경험하고 문헌고찰과 함께 그 1예를 보고하고자 한다.

Various muscular flaps are used in oral and maxillofacial reconstructive surgery for the defects caused by tumor resection and trauma or for the correction of head and neck deformities. The sternocleidomastoid(SCM) muscle may be widely used as a muscular or myocutaneous flap in these lesion. The authors used SCM muscular flap for the expected parotid defect following benign tumor related conservative parotidectomy in three cases. We expected that prevention of post-operative facial deformity, reduction of dead-space and protection of denuded facial nerve etc. is lead by SCM muscular flap. But the total SCM flap can lead to some complications such as "flat neck deformity", limitation of neck movement and overcontouring of parotid defect. Therefore, the authors used split pedicled SCM muscular flap and it lead good favorable results of post-operative functional and esthetic problems.

Facial hyperhidrosis has a symptom of excessive sweating on the face with or without underlying disease. It can be surgically treated by video-assisted thoracic surgery(VATS). We encountered three cases of facial hyperhidrosis which we treated by VATS, which was performed by resection of the lower third of stellate ganglion and T2-T3 sympathetic ganglia with chains. Postoperative symptom was improved in all cases. There were no postoperative complications such as Horner's syndrome or postsympathectomy neuralgia.

The aim of this study was to investigate whether peripheral or central administration of triptolide is involved in pain modulation in inflammatory orofacial pain. The inflammatory orofacial pain was induced by the injection of 5% formalin into right vibrissa pad of rats. The pain behavioral response was measured the number of grooming or scratching on the orofacial area for 9 successive 5 minutes intervals. Triptolide was administrated into the identified vibrissa pad (12.5, 25, $50{\mu}g/50{\mu}l$) or intracisternal space (0.01, 0.1, $1{\mu}g/10{\mu}l$) 10 min before formalin injection. The nociceptive responses were reduced in the 2nd phase (11~45 minutes), particularly 20, 30 minutes after fomalin injection following administration of triptolide into vibrissa pad (25, $50{\mu}g/50{\mu}l$). Intracisternal ($1{\mu}g/10{\mu}l$) administration of triptolide alleviated the formalin-induced pain behaviors in the 2nd phase, especially 25~40 minutes after formalin injection. Triptolide could be a promising analgesic agent in the treatment of inflammatory orofacial pain.
