ReviewPostoperative nausea and vomiting (PONV) after orthognathic surgery: a retrospective study and literature review.
Postoperative nausea and vomiting (PONV) is the most common postoperative complication after surgery and general anesthesia. PONV occurs primarily within the first 24 hours and can lead to significant morbidity, delayed hospital discharge, increased hospital costs and perhaps most importantly, poor patient satisfaction. We sought, in this study, to determine the prevalence of PONV and to identify risk factors in patients who underwent orthognathic surgery. ⋯ We found PONV had a high prevalence among patients undergoing orthognathic surgery. Further studies are needed to develop effective protocols for preventing this common and unpleasant problem.

Microbiology and antibiotic sensitivities of head and neck space infections of odontogenic origin.
The purpose of this study is to assess the anatomical spaces and causative micro-organisms responsible for deep fascial space head and neck infections and evaluate the resistance of antibiotics used in the treatment of these infections. ⋯ Patients who underwent surgical incision and drainage in the operating room had a tendency for involvement of multiple space abscesses with the submandibular space, submental, and lateral pharyngeal spaces effected most frequently. Cultures and sensitivities commonly showed greater growth in aerobes (65.7%) than in anaerobes. Gram positive cocci and gram negative rods had the greatest growth percentage in cultures.

The purpose of this study was to investigate the characteristic and contributory factors of mandibular fractures with abnormal union in China, aiming to produce guidelines to facilitate the management of mandibular fractures so that this complication may be avoided. ⋯ The characteristic of abnormal union is associated with patient's age and gender, severity and type of original trauma, and fracture site. In a sense, the development of abnormal unions is related to the social, economic, and cultural factors in China. At present the key problem of decreasing and avoiding mandibular abnormal unions in our country is to perform appropriate treatment methods in time. At the same time, it is important to obtain patients' compliance during the process of treatment and actively prevent infection.

Management of adenoid cystic carcinoma of minor salivary glands.
Adenoid cystic carcinoma (ACC) is a rare malignant tumor originating from the salivary glands. The characteristic clinicopathologic features of this tumor are perineural spread, local recurrences, and distant metastases. Radical surgery combined with radiotherapy, as mentioned in the literature, is the best method of treatment. This clinical review article is intended to analyze the outcome of management of a group of 22 ACC patients, who were treated in our clinic. ⋯ The most proper method of treatment for ACC seems to be radical resection combined with radiotherapy. The treatment failure is associated with positive margins of the excised surgical specimen and named nerve involvement. The immunohistochemical study of Ki-67 expression may provide additional prognostic information for this tumor.
