Patient positioning is a vital in ensuring patient comfort, dignity and good access to the operative site. Accurate positioning helps in minimising the risk of injury to the patient. An in-house airbag made from recyclable medical supplies can be used to replace the conventional sandbag for head and neck surgeries. It involves the use of an empty irrigation bottle, a valve and suction tubing. Its shape and volume is readily adjustable by altering the volume of inflated air. Moreover, compressible air moulds the bag to the curvature of the patient’s external surface reducing the risk of pressure sores in prolonged surgery. Ultimately this serves as an innovative technique which is financially savvy with the use of recyclable items.

Until now, many kinds of treatment modalities for mandibular angle fractures have been proposed. about among them, the semi-rigid fixation using miniplates has become a most popular procedure due to its simplicity and good clinical results in nowadays. When we use miniplates according to Champy's ideal osteosynthesis line principles for mandibular angle fracture treatment, we generally perform reduction and fixation procedures under the condition of maxillomandibular fixation(MMF) using arch-bars. But in so doing, due to various reasons, we occasionally observe gapping or torqueing of inferior border of mandibular angle after completion of miniplate fixation. In contrast to MMF state, we can observe intimate reduction of inferior border of mandibular angle due to compressive force and gapping of superior border due to tensile forces during wide mouth opening state. So we developed a new technique which uses bone reduction forceps(or modified towel clips) as a temporary fixation device during wide mouth opening state for intimate reduction and stability along the entire fracture line. By applying this new technique for mandibular angle fracture treatment, it was possible for us to perform easy and accurate miniplate fixation for last 1 year period with clinical success. This article presents some case reports of mandibular angle fracture patients who were treated by this new technique and discussions about the reliability and advantages of this technique.

The problem of difficult intubation is well known to anesthesiologists. However, difficulties associated with the extubation of endotracheal tubes are not common, and few reports exist. However, untoward incidents of diverse etiology can occur and the complications of difficult extubation may be fatal. We experienced 2 cases of difficult extubations. One was due to adhesion of the tube to the tracheal wall and the other was due to a fold in the deflated cuff of an excessively large-sized tube. We managed these difficult extubations by rotating the tube with a MaGill forcep under direct laryngoscopy. We report upon these clinical experiences and include a brief review of the literature.

A study on 54 cases of instrumental labours by forceps with youngest of 18 and oldest of 40 of which 50 cases experienced the first labor. The causes of forceps delivery comprised the long exert oneself, weak exert oneself. The forceps labor was the third rank in the induced labor.

Nguyen Thanh Nhu has made a modified trocar: The Saigon trocar (patent pending) easy to be made in Vietnam, easy to use, safe, easy to maintenance and sterilisation, used with a 18F Foley catheter. We have performed cystostomies by using the Saigon trocar to put Foley catheters of 18F for 70 patients and by open surgery to put Foley catheters of 22F for 40 patients at Binh Dan hospital and 115 People Hospital in 1999. No operative complication has been recorded for trocar cystostomy: however, 7 failed cases because the procedure has not been carried out properly, had to be switched to open surgery. Using the Saigon trocar to perform suprapublic cystostomy reduces significantly procedure time and post-operative days, therefore the treatment cost is reduced (roughly 500000 VND/case). To prevent from complications, the procedure must be right indicated and done with good care (bladder volume >330ml, puncture perpendicularly to the abdominal wall).

The purpose of this study was to investigate the quantity of debris which was extruded apically after canal instrumentation using different types of enlarging instrument in endodontic resin models. Five groups of 9 endodontic resin models were instrumented using each different technique : hand instrumentation without early coronal flaring, hand instrumentation after early coronal flaring, and three nickel-titanium engine-driven instrumentations (Hero 642, Protaper, K3). Debris extruded from apical foramen during instrumentation was collected on preweighed CBC bottle, desiccated and weighted using electronic balance. The results were analyzed using Kruskal-wallis test and Mann-Whitney U rank sum test at a significance level of 0.05. The results were as follows: 1. All of instrumentation techniques produced apically extruded debris. 2. Group without early coronal flaring extruded significant more debris than groups with early coronal flaring. 3. There was no significant difference among early coronal flaring groups. The early coronal flaring is very important to reduce the amount of debris extruded apically.

After laparoscopic surgery, most cases of incisional hernia occur when a trocar greater than 10 mm is used and this rarely occurs when a 5 mm trocar is used. We recently experienced two cases of incisional herniation at a 5 mm port site in connection with withdrawal of the drain after laparoscopic procedure.

Small bowel herniation after operative laparoscopy is an uncommon but serious complication that can result in bowel resection. Therefore, it is important to prevent and diagnose early. We experienced a case of small bowel herniation through trocar site and present with a brief review of literatures.
