Subcutaneous emphysema is one of complications followed by trauma and surgical operation. Clinically, subcutaneous crepitation is noticible by presence of air in the soft tissues. Common signs and symptoms of subcutaneous emphysema and pneumomediastinum are dyspnea, chest or back pain. Hamman s sign, and positive x-ray findings. The roentgenogram of the chest is diagnostic in that we notice radiolucent lines outlining the edges of the mediastinum and the cardic shadow. The clinical importance of subcutaneous emphysema is that the migration of air to the mediastinum can cause death. We report a case of subcutaneous and mediastinal emphysema that generally entaills facial, cervical and thoracic crepitation, swelling and severe chest pain on use of air turbin at surgical extraction of mandibular impacted third molar.

The inferior alveolar or mental nerves may be damaged during several routine surgical procedures on the madible These include removal of wisdom teeth, various grafting for mandibular augmentation and implantation procedures, etc. Therefore, intentional reposition of the inferior alveolar nerve doesn t only facilitate various surgery but also minimizes damage to infeior alveolar nerve which has been indicated as adjunctive techniques for orthognathic surgery, vestibuloplasty, and implantation of atrophied posterior mandible. We have done that repositioning of the inferior alveolar nerve for mandibular body osteotomy, rigid internal fixation ot fractured mandible, en bloc resection of ameloblastoma, enucleation of radicu-lar cyst, and implantation of the atrophied posterior mandible. So, it was possible for us to facilitate RIF for immediate repair of the continuity defect near the mental foramen without retraction of mental nerve We could lessen the risk of iatrogenic nerve damage and complete removal of lesion during the enucleation of intrabony lesion approximated neurovascular bundle. The effect of vertical height augmentation of mandible tor implant has made superior functional restorative rehabilitation during the implantation of atrophied posterior mandible. Neurosensory evaluation was performed using the two-point discrimination test. All patients have immediated neurosensory alteration associated with the neurovascular bundle manipulations. 5 Patients with unilateral reposition had good recovery and returned to normal neurosensory function in 12 to 21 months postoperatively. As for the case of one patient with bilateral reposition only 4 months of followup period has passed. So the result remains to be seen. The approach mentioned above has got a good result in minimzing the long-term neurosensory disturbances and facilitating various mandibular surgery. This paper, therfore, reports on the literature on the matter.

미각 회복을 위한 무구개 의치(Palateless Complete Denture)의 임상증례

송언희,김래경,안현정,변숙,최병갑,Song, Eon-Hee,Kim, Rae-Gyoung,Ahn, Hyun-Jeong,Byun, Sook,Choi, Byeong-Gap 대한치과보철학회 1999 대한치과보철학회지 Vol.37 No.6

The purpose of this article is to present a clinical case report for palateless complete denture. Despite the contravacy of palatal uncoverage in upper complete denture, palateless complete denture has some merits for upper edentulous patient. Following the uncovering of the palatal portion, the patient became easy to talk and restored the lost good tastes. He is happy despite of the decrease of the retention of the upper complete denture. Palateless complete denture is a compatible alternative fir upper edentulous patients in cases of gagging, large palatal torus and restoring the lost good tastes. The clinical points are as follows : 1. The remaning alveolar ridge should be ovoid and have enough width and height for the sup-port and retention. 2. The patient must have strong wish to the palateless complete denture. 3. Palatal beading made on the palatal peripheral border give good border sealing of the palatal flange and minimaized the prominence of the denture flange 4. The peripheral border of the palatal flange should be reduced as thin as possible for more comfort. 5. Upper artificial posterior teeth should be arranged over the alveolar ridge crest and inner incline of the buccal cusp relieved for denture stability while chewing. 6. For stability of palateless complete denture, bilateral balanced occlusion should be sttained. Palateless complete denture will restore the lost good tastes and more comfortable and physiologic to upper edentulous patients and a good alternative to full palatal coverage complete denture in the properly selected cases.

협골체 골절시 접근방법은 안와하연에 대해 섬모하절개, 하안검절개, 안와하연절개 및 결막절개등이 사용되고 안와측벽, frontozygomatic suture에 대해서는 lateral brow incision, 상안검절개등이 사용되며 관상절개술은 frontozygomatic suture 와 협골궁에 접근할 수 있다. 관상절개술을 제외한 접근방법은 한가지 절개술로 단지 한부위의 정복과 고정술이 가능하므로 결국 협골체 골절시 2점이상 고정을 할 경우 2가지 이상의 절개가 필요하게 된다. 이에 저자들은 관상절개술의 적응증이 아닌 협골체 골절에 lateral canthotomy-conjunctival incision을 사용하여 안와하연 및 측벽의 골절부에 대한 정복술과 고정술을 시행하여 양호한 결과를 관찰하여 이에 보고하는 바이다. Various extraoral and intraoral approaches to reduction and fixation of zygomatic complex fractures were used. The method for exposure of inferior orbital area include the subciliary, inferior eyelid, infraorbital rim and conjunctival incisions. For exposure of frontozygomatic suture, lateral brow, coronal and blephaloplasty incisions were used. It is necessary that the usual approaches to the inferior and lateral orbit have two incisions. However, lateral canthotomy-conjunctival approach presented on this paper provide optimal exposure to lateral and inferior orbit.
