Background: The conventional cervicofacial flap may cause the aesthetic problem of sideburns with a mismatched shape and arrangement. We developed a modified method with the goals of minimizing the destruction of the shape and arrangement of the sideburns and minimizing complications in comparison with the conventional method. Methods: The incision line was designed to descend just in front of the sideburns, without passing through them, and then to ascend with the sideburns posteriorly when a cervicofacial flap is performed, unlike the conventional method. Patients in whom this method was applied (group B) and patients who underwent surgery using the conventional method (group A) were investigated in a retrospective study. The method was evaluated by assessing changes in the arrangement of the sideburns and patients' satisfaction, and differences in the complication rate. Results: In group A, 23 of the 31 patients experienced changes in the arrangement of their sideburns. Most patients who experienced a change in the arrangement of their sideburns were dissatisfied with the change. The patients in group B did not experience such changes, and the defects were well reconstructed. Most of them were satisfied with the final sideburn arrangement. Conclusion: A novel method was used to preserve the sideburns while performing a cervicofacial flap. As a result, the appearance of the sideburns was well preserved and the satisfaction of patients was also high. Moreover, this technique could also prove useful for reconstruction without any increase in complications compared to the conventional method.

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.

Spontaneous rupture of the pulmonary alveoli after a sudden increase intra-alveolar pressure is a common cause of pneumomediastinum, which is usually seen in healthy young men. Other common causes are traumatic and iatrogenic rupture of the airway and esophagus; however, pneumomediastinum following cervicofacial emphysema is much rarer and is occasionally found after dental surgical procedures, head and neck surgery, or accidental trauma. We present two cases of pneumomediastinum following cervicofacial subcutaneous emphysema after oral trauma. They constitute an uncommon clinical entity, So its radiologic appearance, clinical presentation, and diagnosis are described.

Subcutaneous facial emphysema after dental treatment is an uncommon complication caused by the invasion of high-pressure air; in severe cases, it can spread to the neck, mediastinum, and thorax, resulting in cervical emphysema, pneumomediastinum, and pneumothorax. The present case showed subcutaneous cervicofacial emphysema with pneumomediastinum after class V restoration. The patient was fully recovered after eight days of conservative treatment. The cause of this case was the penetration of high-pressure air through the gingival sulcus, which had a weakened gingival attachment. This case indicated that dentists should be careful to prevent subcutaneous emphysema during common dental treatments using a high-speed hand piece and gingival retraction cord.

경안명 괴사성 근막염은 높은 사망률을 가진 치명적인 질환이나 혈류가 풍부한 두경부에서는 거의 발생하지 않고 피부에 괴사를 보이지 않는 경우도 많아 두경부에 발생한 감염증의 진단시에 그 가능성을 고려하지 않는 오류를 범하기 쉽다. 따라서, 일단 발생한 경우 오진 또는 뒤늦은 진단으로 환자의 생명을 위협하게 될 수 있다. 이의 진단에는 임상적 검사상 촉진시 느껴지는 염발음이 가장 중요하고 이환 부위의 종창, 악취, 지저분하고 창백하며 붉은 빛을 띠는 피부 표면의 모습, 절개 시 회색빛의 구정물과 같은 삼출물 등이 참고자료가 될 수 있으며, 컴퓨터 단층사진의 촬영을 통해 피하조직의 공기 방울이나 공기 주머니를 확인하고 hemolytic Streptococci등의 균배양 결과를 종합적으로 판단함으로써 더욱 정확한 진단이 가능해지고, 치료방법으로는 빠르고 광범위한 외과적 처치와 대량의 항생제 투여가 가장 중요하고 고압산소요법 등 기타 보조적 처치법을 적절히 시행한다면 좋은 결과를 얻을 수 있을 것으로 사료되었다.

방선균증은 그람 양성 혐기성 균인 악티노미세스과 (Actinomycetaceae)로 인하여 발생하며, 안구 감염의 원인으로서의 방선균증은 드물다고 알려져 있다. 저자들은 60세 남자에게서 발견된 안구 봉와직염을 포함한 경부안면형과 중추신경계형 방선균증의 자기공명영상 소견을 보고하고자 한다. T1 강조 안구 자기공명영상에서 안구를 비롯한 두경부에 다수의 비정상적 조영증강 병변이 보였으며, 일부에서는 농양들으로 생각되는 저 신호강도들을 포함하고 있었다. 병변은 절개 생검을 통하여 방선균증으로 진단되었고, 이후 페니실린계 항생제를 사용하여 완치되었다.

Objectives: Infection involving the orbit, zygomatic space, lateral pharyngeal space, or hemifacial and oral floor phlegmon is referred to as cervicofacial infection (CFI). When diagnosis and/or adequate treatment are delayed, these infections can be life-threatening. Most cases are the result of odontogenic infections. We highlight our experiences in the management of this life-threatening condition. Materials and Methods: This was a retrospective study of patients who presented with CFI from December 2005 to June 2012 at the Oral and Maxillofacial Surgery Clinic or the Accident and Emergency Unit of Ahmadu Bello University Teaching Hospital (Zaria, Nigeria). The medical records of all patients who presented with either localized or diffuse infection of the maxillofacial soft tissue spaces were retrospectively collected. Data collected was analyzed using SPSS version 13.0 and are expressed as descriptive and inferential statistics. Results: Of the 77 patients, 49 patients (63.6%) were males, a male to female ratio of 1:7.5. The ages ranged from two years to 75 years with a mean of $35.0{\pm}19.3$ years, although most patients were older than 40 years. The duration of symptoms prior to presentation ranged from 6 to 60 days, with a mean of $11.0{\pm}9.4$ days. More than 90% of the patients presented to the clinic within the first 10 days. The most commonly involved anatomical space was the submandibular space (n=29, 37.7%), followed by hemifacial space (n=22, 28.6%) and buccal space (n=7, 9.1%). Ludwig angina accounted for about 7.8% of the cases. Conclusion: CFI most commonly involves the submandibular space, typically affects individuals with a low level of education, and is influenced by traditional medical practices. Despite improved health care delivery, CFI remains a significant problem in developing countries.

Actinomycosis is a subacute or chronic suppurative infection caused by Actinomyces species, which are anaerobic Gram-positive bacteria that normally colonize the human mouth and digestive and urogenital tracts. Cervicofacial actinomycosis is the most frequent clinical form of actinomycosis, and is associated with odontogenic infection. Characterized by an abscess and mandibular involvement with or without fistula, but the cervicofacial form of actinomycosis is often misdiagnosed because the presentation is not specific and because it can mimic numerous infectious and non-infectious diseases, including malignant tumors. We report a rare case of actinomycosis infection with coexisting submandibular sialolithiasis. The patient presented with a $1{\times}1cm$ abscess-like lesion below the lower lip. Punch biopsy of the lesion revealed atypical squamous cell proliferation with infiltrative growth, suggestive of squamous cell carcinoma. The patient underwent wide excision of this lesion, where the lesion was found to be an abscess formation with multiple submandibular sialolithiases. The surgical specimen was found to contain Actinomyces without any evidence of a malignant process. We assumed that associated predisposing factors such as poor oral hygiene may have caused a dehydrated condition of the oral cavity, leading to coexistence of actinomycosis and sialolithiasis.
