We report two rare cases of extensive bilateral subcutaneous emphysema that occurred during ordinary dental procedures. An air-driven high-speed handpiece, routinely used in dental procedures may cause subcutaneous emphysema when high pressure air is introduced into the loose connective tissues below the dermal layer. The first case occurred with surgical extraction of the lower third molar. The air introduced into the fascial spaces near the surgical field spread to the contralateral spaces, as well as the neck and chest areas. The second case also showed extensive bilateral subcutaneous emphysema caused by the introduction of compressed air from the handpiece during crown preparation without any invasive procedure. Cases where the emphysema extends beyond the treatment site to involve the contralateral cervicofacial areas have been rarely reported. Predicting the occurrence of subcutaneous emphysema is difficult, so it is important to exercise caution during routine dental treatment. If significant bilateral cervicofacial swelling is suspected to be due to subcutaneous emphysema, prompt diagnosis with securing the patient's airway will be necessary.

Background Lymphatic malformation (LM) is a form of congenital vascular malformation with a low incidence. Although LM has been studied, no consensus has emerged regarding its cause or treatment. Methods In this study, we retrospectively evaluated 40 patients who visited our vascular anomalies center for the treatment of cervicofacial LM, which is a common manifestation of LM. The medical records of patients over a period of 12 years were reviewed and analyzed for commonalities regarding the diagnosis and the results of treatment. Results Suspected cervicofacial LM was confirmed through imaging studies. No difference in incidence was observed according to sex, and 73% of patients first presented with symptoms before the age of two years. The left side and the V2-V3 area were most commonly affected. No significant differences in incidence were observed among the macrocystic, microcystic, and combined types of LM. A total of 28 out of 36 patients received sclerotherapy as the first choice of treatment, regardless of the type of lesion. Complete resolution was achieved in only 25% of patients. Conclusions LM is important to confirm the diagnosis early and to choose an appropriate treatment strategy according to the stage of the disease and each individual patient's symptoms. When treatment is delayed or an incorrect treatment is administered, patient discomfort increases as the lesion gradually spreads. Therefore, more so than is the case for most other diseases, a team approach on a case-by-case basis is important for the accurate and appropriate treatment of LM.

Traumatic asphyxia is a distinctive clinical syndrome characterized by cervicofacial cyanosis and edema, bilateral subconjuctival hemorrhage, and multiple petechiae of the face, neck, and upper part of the chest after a severe compressive crush injury of the thorax or of the upper part of the abdomen.The pathophysiologic mechanism of traumatic asphyxia is reflux of blood from the heart retrograde through the valveless superior vena cava and the great veins of the head and neck by severe compression of the thorax or the abdomen.We experienced one case of the traumatic asphyxia, and its clinical features are discussed.

외상에 의한 안면부의 반흔 및 안면 종양에 의한 결손은, 사회적 적응면에서 고찰할 때, 환자 자신에 대한 심리적 부담 및 타인에 대한 혐오감을 유발시킨다. 그러므로 안면부의 반흔 구축 및 결선 수복은 환자의 사회적 적응을 쉽게 유도해야 하며 방법적인 면을 고려할 때, 보다 심미적인 결과를 추구해야 한다. 일반적으로 안면 반흔의 구축 및 결손의 수복 방법에는 피부 이식 또는 피판 이식이 이용되고 있으나, 원거리 피부 의식의 결과, 안면부의 피부와 상이한 양태를 나타내고 있어 심미적이지 못하며, 안면부에서의 피판 이식은 수복할 수 있는 반흔 및 결손의 범위가 제한되어 있는 결점이 있다. 경안 피판에 의한 반흔 구축 및 결손 수복은 와반증을 동반할 수 있는 단점이 있으나, 혈류 공급이 우수하고, 봉합후 반흔이 적으며, 보다 광범위한 반흔 및 결손을 수복할 수 있고, 안면부 피부와 성상이 유사하여 보다 심미적이다. 본 교실에서는 화상에 의한 안면부 반흔과 혈관종 절제술에 의한 결손 수복에 경안 피판을 이용하여 심미적으로 우수한 결과를 얻었기에 저자등은 문헌 고찰과 함께 증례 보고를 하는 바이다.

Necrotizing fascitis is a severe soft tissue infection characterized by extensive necrosis of superficial fascia, suppurative fascitis, vascular thrombosis, widespread undermining of surrounding tissues. Associated systemic problems are widespread undermining of surrounding tissues, Associated systemic problems are common, with chronic alcoholism and diabetes being most prominent. Most commonly this disease presents in the extremities, trunk, and perineum. Necrotizing fascitis of dental origing is rare and its fulminating clinical course is not well documented in the dental literature. The present report is a case of necrotizing fascitis following vital extirpation of the pulp in a patient with uncontrolled diabetes mellitus and liver cirrhosis. Originally throught to be caused by hemolytic streptococcus organism or stphylococcus aureus, advances in anaerobic culturing have shown it to be a synergistic bacterial infection involving aerobic and ovligate anaerobes. it is relatively rare in relatively rare in haea and neck regions. If it was not diagnosed and treated in early stages, necrotizing fascitis can be potentially fetal, with a mortality rate approaching 40%. It's treatment requires early recognition, prompt and aggressive surgical debriment and proper supportive cares, such as, antibiotic therapy, fluid resuscitation and correction of metabolic and electrolyte disorder, resolving of the underlying systemic disease. Recently, we experienced two cases of necrotizing fascitis in cervicofacial region, One patient was 60 years old male with uncontrolled Diabetes Mellitus and other patient was 48 years old with steroid therapy during 30 years. Local surgical wound healing was successful but, patients were died after admission, because of lung abscess, gastrointestinal bleeding, septic shock and respiration hold.

A large lateral facial defects especially a through and through defect of the cheek remains as challenging field of reconstruction for the head and neck surgeons. Closure of these wounds is technically troublesome due to the magnitude and location of the soft tissue and skin defect, functional and aesthetic consideration. optimal cancer surveillance, and desire for good nourishment. Most traditional methods dealing with these defects, including split-thickness skin graft, local and regional flaps as well as musculocutaneous flaps have their limitations. We applied four different methods for these reconstruction in four cases. We utilized temporal muscle flap, forearm free flap and secondary healing for repair of mucosal defects, and medial base cervicopectoral flap, pectoralis major myocutaneous flap and cervicofacial flap for the reconstruction of external skin defects. In one case, both sides were reconstructed with single forearm free flap. In our experiences, secondary healing could be one of the useful method for mucosal repair in the defect between upper and lower gingivobuccal sulcus. However, forearm free flap was thought to be more ideal for the cases with mandibulectomy. For the external repair, the regional skin flap was considered to be superior to pectoralis major myocutaneous flap or forearm free flap especially on color matching.

Cervicofacial subcutaneous emphysema is a rare complication mainly resulting from dental procedures. The majority of cases are self-limiting and benign in clinical nature. However, although entry sites may be quite small and superficial, it can result in potential respiratory difficulties, such as pneumothorax and pneumomediastinum. We present the first case in which facial subcutaneous emphysema developed in a 6-year-old boy following use of a fish cake skewer while eating.

Actinomycosis is an unusual granulomatous infection caused by gram-positive anaerobic bacteria called Actinomyces species(predominantly Actinomyces israelii), which is a common and normally nonpathogenic organism found in the nose and throat. The three major clinical presentations of actinomycosis include the cervico-facial(the most common, 55%), thoracic, and abdominopelvic region. Actinomycosis typically has a chronic, indolent course characterized by swelling and induration of the soft tissues and eventual spontaneous drainage through multiple sinus tracts. Actinomycosis is difficult to diagnose because of variable presentation mimicking neoplasm and fastidious nature of the organism in culture. We present a case of actinomycosis in the parotid tip area which was mistaken for a salivary tumor.

Hamman 증후군으로 불리기도 하는 종격동기흉은 종격동의 근막내부에 공기가 존재하는 질환이다. 드물지 않게 종격동과 경부 근막 사이의 교통공간을 통해 공기의 확산이 발생할 수 있다. 이런 종격 동기홍의 원인은 기도-기관지 질환 및 식도손상이지만 대부분의 경우에 명확하지가 않다. 몇몇의 증례에서 Macklin효과가 원인으로 알려져 있다. 저자들은 흉부 외상 후 발생한 종격동기흉의 원인으로 전산화단층촬영에서 확인된 Macklin효과의 증례가 있어 이를 보고하고자 한다.
