To explore the effect of negative pressure sealing drainage on the treatment of maxillofacial-neck-mediastinal infection in multiple spaces.

Vacuum sealing drainage (VSD) was applied in five patients with maxillofacial-neck-mediastinal infection caused by odontogenic infection accompanied by diabetes or renal failure and other systemic diseases. After extensive debridement, a negative pressure drainage sponge was placed in the pus cavity and then the wound was closed. Continuous negative pressure drainage was continued after the operation. At the same time, multidisciplinary consultation was applied to control basic diseases and, strengthen anti-inflammatory responses, and nutrition and other systemic treatments were applied.

Four patients underwent continuous negative pressure drainage and successful removal of the negative pressure sponge after inflammatory symptoms subsided. One patient′s inflammatory symptoms became more serious after the operation, and we performed another operation to change the placement of the negative pressure sponge. All 5 patients underwent VSD with negative pressure sponge replacement ranging from 1 to 3 times during treatment. After multidisciplinary consultation, they were all cured and discharged from the hospital.

For infection of the mediastinum, maxillofacial region and neck, local treatment and systemic treatment are emphasized, as well as the treatment of infected lesions and basic diseases. Negative pressure closure and drainage technology promotes the alleviation of inflammation, and multidisciplinary combined treatment is beneficial for the control of basic diseases.

To evaluate the value of Kirschner wire internal fixation in the treatment of sagittal mandibular condylar fractures.

From January 2019 to January 2020, 13 patients (19 sides) with mandibular condylar sagittal fracture treated by Kirschner wire internal fixation at the Stomatological Medical Center, Foshan Hospital of Traditional Chinese Medicine were retrospectively analyzed. After conventional surgical incision and exposure and reduction of the mandibular condyle, 2-4 Kirschner wires were used for fixation, and other maxillofacial fractures were treated simultaneously. The reduction accuracy and stability of the free mandibular condyle were evaluated by CBCT one week after the operation, and the occlusion relationship, opening degree and opening type were evaluated by clinical examination.

All patients had good fracture alignment and no twisting, breaking or loosening of the Kirschner wire. The occlusion relationship, opening degree and opening shape recovered well after the operation.

Kirschner wire is effective in treating sagittal fractures of mandibular condyles.

To review the clinical data of 3050 patients with maxillofacial trauma in order to provide guidance for clinical diagnosis and treatment.

During January 2010 to December 2014, 3050 maxillofacial traumatic patients were selected in Foshan Hospital of Traditional Chinese Medicine, Guangzhou University of Traditional Chinese Medicine in this retrospective analysis regarding data of sex, age, causes of injury, occupation, geographic distribution, blood type, fracture site, multiple associated injuries, first admitted department, treatment result were reviewed.

The male and female ratio was 3.9∶1.1. 711 cases (56.1%) were between 20 to 40 years old. The traffic accident (1055 cases, 34.6%) was the first traumatic cause. The zygomatic complex (707 cases, 23.2%), naso-orbitalethmoid (650 cases, 21.3%), mandible (540 cases, 17.7%) were most vulnerable. Maxillofacial injury was often associaed with brain injury (1321 cases, 43.3%) and facial soft tissue contusion (1275 cases, 41.8%). For the 2632 maxillofacial fracture patients, the first admitted department included stomatology department (67.3%), orthopaedics (11.6%), brain surgery (8.4%), et al. The average score of AIS was 2.3 which was between moderate and severe. The treatment included operation treatment (1694 cases, 55.5%), and conservative treatment (1356 cases, 44.5%).

Male took the majority part of injury for the maxillofacial traumatic patients. The 20 to 40 year old people occupated the highest proportion. Traffic accident was the first cause of injury meanwhile the fall injury proportion rose. Zygomatic complex, naso - orbital - ethmoid, mandible fracture were the most vulnerable injuries. Maxillofacial injury often combined with brain, chest, abdomen and other important organs. The patients were adimtted to the appropriate department according to the injury. The overall treatment effect was satisfied.

To explore the effects of mouth floor approach intubation in the treatment of jaw fracture combined with skull base injury.

From Jan. 2014 to Oct. 2015, 7 cases of jaw fracture combined with skull base injury were selected from Medical center of Stomatology, Foshan Hospital of Traditional Chinese Medicine (FST-CM). All cases were treated with mouth floor approach intubation, because they were not suitable to be given the oral or nasal intubation anesthesia.

All the patients healed well after operation, and there was no tube accident or other complications.

For patients of jaw fracture combined with skull base injury, the mouth floor approach intubation could be recommended as a supplementary choice for traditional intubation methods.
