Randomized Controlled Trial Comparative StudyEffect of single dose preoperative intramuscular dexamethasone injection on lower impacted third molar surgery.
This study aimed to investigate the effects of dexamethasone intramuscular injection 1h preoperatively, in reducing facial swelling, pain and trismus after lower impacted third molar (LITM) surgery. Twenty healthy Thai patients with both LITM surgical extraction were enrolled in the study. The washout period was 1 month after the first operation. ⋯ Additionally, the amount of paracetamol decreased significantly. There were no significant differences in trismus in the study and control groups 7 days after LITM operation. Single-dose intramuscular injection of dexamethasone can reduce postoperative facial swelling and pain, without affecting trismus after LITM surgical extraction.

In most rhinoplasty procedures, osteotomies are usually required. The osteotomy areas are innervated by sensory branches of the trigeminal nerve. The trigeminocardiac reflex (TCR) is clinically defined as the sudden onset of parasympathetic activity during stimulation of the trigeminal nerve. ⋯ TCR was detected in nine patients following lateral osteotomies and nasal pyramid infracture procedures (8.3%). The authors determined that LAC injection prior to osteotomy did not prevent TCR. Manipulation at or near the infraorbital nerve during rhinoplasty may cause TCR, even if local anaesthetic infiltration is used.

Writing a paper for publication in a peer-reviewed journal is a rewarding experience but a very difficult undertaking that requires years of experience, determination and patience. The exponential rise of knowledge has resulted in the exponential rise of manuscripts submitted for publication in the various peer-reviewed journals all over the world. Potential authors are not only having to write high-quality papers to get published, but also have to compete with other authors for the limited journal space available to publish their papers. The purpose of this article is to highlight some of the ways of making the task of getting published in peer-reviewed journals easier to achieve.

Sodium iodoacetate induced osteoarthrosis model in rabbit temporomandibular joint: CT and histological study (part I).
Studies to elucidate the pathophysiology of osteoarthrosis have been hampered by the lack of a rapid, reproducible animal model that mimics the histopathology and symptoms associated with the disease. The aim of this study is to evaluate the radiological, histological and histomorphometrical findings of four different concentrations of sodium iodoacetate (MIA) to create osteoarthrosis by using an arthrocentesis technique on rabbit temporomandibular joint (TMJ). 12 New Zealand white male rabbits received an injection of MIA (50 μl dose of 1.5, 2, 2.5, 3mg/ml concentrations) to a single joint of each group by arthrocentesis. Computed tomography (CT) images were obtained pre- and post-injections at 2, 4 and 6 weeks. ⋯ The mean subchondral bone volume depended on the concentration of MIA and was 62±2.6%, 63±4.1%, 42±3.6% and 38±3.8%, respectively. A minor abnormality was found on CT in six joints at the 4-week follow up. MIA injection and arthrocentesis offer a rapid and minimally invasive method of reproducing histologically osteoarthrotic lesions in the rabbit TMJ.

Proposal for a 'surgical checklist' for ambulatory oral surgery.
The authors propose a new checklist model adapted for ambulatory oral surgery procedures based on the 'surgical checklist' proposed by the WHO. The proposed document contains 18 items divided into two sets: those that must be verified before beginning surgery and those that must be verified after its completion, but prior to the patient's departure from the site where the surgery is performed. A checklist is an easy-to-use tool that requires little time but provides order, logic and systematization taking into account certain basic concepts to increase the level of patient safety. The authors think that the result is a checklist that is easy to complete and ensures that key patient safety-related matters are dealt with in this field of surgery.
