Subcutaneous cervicofacial, mediastinal emphysemas are complications associated with head and neck surgery, trauma, infectious processes, tooth extraction. Drill cooling stream and dental syringe air ject are the sources of high pressure air that may enter exposed soft tissue. Since the introduction of the high-speed air turbine drill in the 1960s, The incidence of iatrogenic subcutaneous emphysema has increased. Most cases begin to resolve after 2 to 3 days and residual swelling is usually minimal at the end of 7 to 10 days. Surgical approach is not advised because it is likely to be ineffective. The differential diagnosis of neck swelling after dental procedure includes hematoma, cellulitis, angioedema, allergic reaction, subcutaneous emphysema. We report a rare case of patient with subcutaneous cervicofacial emphysema and mediastinal emphysema secondary to third molar extraction.

Pneumomediastinum and subcutaneous emphysema produced by air turbine dental drills, although widely reported in dental publications, are rarely reported in the thoracic journals. We report a case of 38-year-old man with pneumomediastinum and subcutaneous emphysema after use of a air turbine dental drill for dental extraction.

Subcutaneous emphysema is relatively rare postoperative complication in the oral and maxillofacial region. Most cases reported in maxillofacial area relate to the use of high-speed handpiece. However, in this case, subcutaneous emphysema was caused by compressed air blow performed during suture removal. Cone-Beam Computed Tomography was conducted to evaluate the extent of diffusion bubbles.. In this report, we describe etiology, diagnosis, prevention and management of subcutaneous emphysema in the maxillofacial area.

Subcutaneous emphysema is a benign condition following trauma (pneumothorax and oropharyngeal), cervical or thoracic procedures, and mediastinal infection. However, severe subcutaneous emphysema may be related to serious complications such as respiratory failure, airway compromise, and tension- related phenomena. Many alternative therapies have been tried to treat patients with this condition. We report our experience with vacuum-assisted closure therapy for treating patients with severe subcutaneous emphysema.

Lateral pharyngoplasty is a surgical option for treatment of obstructive sleep apnea (OSA). Here, we present a case involving a 40-year-old healthy man who underwent surgery, including lateral pharyngoplasty and robotic tongue base resection, for OSA. There were no intraoperative or immediate postoperative complications. However, on postoperative day 3, the patient presented with swelling in the temporal and buccal areas and was diagnosed with subcutaneous emphysema, later confirmed by computed tomography. The patient was carefully monitored under conservative care and discharged without complications. Although subcutaneous emphysema following tonsillectomy is a rare complication and usually resolves with conservative management, in certain cases, it might require surgical intervention. Lateral pharyngoplasty involves tonsillectomy and additional incision along the tonsillar fossa, which makes it susceptible to pharyngeal wall defects and, consequently, subcutaneous emphysema. Additionally, lateral pharyngoplasty and robotic tongue base resection cause pain and might thus contribute to the increase in intrapharyngeal pressure, which might aggravate subcutaneous emphysema. Lateral pharyngoplasty should be performed with meticulous dissection of the superior pharyngeal constrictor muscle. Healthcare providers should be aware of these complications and, upon suspicion of the same, place the patient under close observation to prevent life-threatening situations.

Subcutaneous emphysema defines collection of air in subcutaneous spaces of body. It is usually originated from air in upper airway and lower respiratory tract such as larynx, trachea, bronchus and lungs. Air in subcutaneous spaces derives from leakage of air due to tearing or ruptures of airway structures, and also accompanies pneumothorax or pneumomediastinum and/or rib or sternal fractures or other major airway injuries. We experienced a case of subcutaneous emphysema caused by laryngeal injury without any associated airway injuries at neck from motorcycle accident, so we would report a case with the review of literatures.

Cervicofacial subcutaneous emphysema is defined as the abnormal introduction of air into the subcutaneous tissues of the head and neck. It is mainly iatrogenic and traumatic in origin. Our two case reports are also due to the same cause, but the features of the trauma and the site of the dental treatment are different from the existing reports. A 29-year-old man visited our hospital with facial swelling and pain after experiencing facial trauma in a soccer game. Another 55-year-old woman visited with similar symptoms after replacement of her maxillary anterior fixed prosthesis. In the two cases presented, subcutaneous emphysema was gradually treated with no complications during antibiotic prophylaxis and supportive care. In this paper, we report two cases of traumatic and iatrogenic subcutaneous emphysema and their diagnoses, etiologies, complications, and treatments based on a literature review.

Objectives: The objective of this study was to analyze 11 cases of subcutaneous emphysema associated with dental procedures from a single hospital and discuss approaches for accurate diagnosis and treatment of the condition. Materials and Methods: The medical records of 11 patients who were treated for subcutaneous emphysema related to dental procedures between January 2009 and April 2017 were analyzed retrospectively. Patients with subcutaneous emphysema within the facial area or that spread to the neck and beyond, including the facial region, were assigned to two groups and compared in terms of age, sex, and durations of antibiotic use, hospitalization, and follow-up until improvement. The correlation between location of the origin tooth and range of emphysema spread was analyzed. Results: The average durations of antibiotic use during conservative treatment and follow-up until improvement were 8.55 days (standard deviation [SD], 4.46 days) and 1.82 weeks (SD, 1.19 weeks), respectively. There was no intergroup difference in duration of antibiotic use (P=0.329) or followup (P=0.931). Subcutaneous emphysema was more common after dental procedures involving the maxilla or posterior region than after those involving the mandible or anterior region. There was no significant difference in air distribution according to location of the air orifice (maxilla, mandible, or both; P=0.106). Conclusion: Upon adequate conservative treatment accompanied by prophylactic antibiotic treatment considering the risk of infection, patients showed signs of improvement within a few days or weeks. There was no significant difference in treatment period between patients with subcutaneous emphysema localized to the facial region and those with subcutaneous emphysema spreading to the neck or beyond. These findings need to be confirmed by analysis of additional cases.

61세 만성폐쇄폐질환 남자 환자로 호흡곤란을 주소로 내원하여 만성폐쇄성폐 질환 급성 악화 진단 하에 입원치료를 시작하였다. 입원치료 도중 다량의 자발성 피하공기증이 생기면서 호흡곤란이 악화되어 다수의 16 gauge 정맥용 도관 을 빗장중간선에 삽입하고 배출을 시도하였다. 그러나 피하공기증이 더욱 악화되어 wall suction으로 지속적인 흡인을 하였고 이후 피하공기증의 관해를 확인 할 수 있었다. 저자들은 16 gauge 정맥용 도관을 이용한 지속흡인으로 비침습 적이고 간편하게 피하공기증을 치료하였기에 문헌고찰과 함께 보고하는 바이다.
