Randomized Controlled Trial Comparative Study
Effects of lidocaine infiltration on cost of rhinoplasty made under general anesthesia.
This study aimed to compare the effects of combined and noncombined lidocaine with adrenaline infiltration in general anesthesia (GA) procedures, in which the standard anesthesia depth is monitored by Bispectral Index monitoring, on minimum alveolar concentration (MAC) levels and the costs. Following approval by the local ethics committee, an American Society of Anesthesiologists physical status I–II group of 40 adult patients for whom elective rhinoplasties under GA were planned was divided into 2 double-blind randomized groups. In group 1, GA and lidocaine + adrenaline were administered, whereas in group 2, only GA and adrenaline were administered. ⋯ In group 1, the MAC% was 20.83% lower than that of group 2; the consumed desflurane amount was 20.29%, and the cost was 20.29% lower than that of group 2 (P < 0.05). In rhinoplasties under GA, the lidocaine + adrenaline combination infiltration not only decreased inhaled anesthetic requirement and cost but also supported the hemodynamic stability. In addition, surgical satisfaction increased in the lidocaine + adrenaline group because of small number of agitated patients during the recovery period.

The aim of this prospective study was to evaluate and compare the epidemiology and pattern of maxillofacial injuries caused by stumbling and other kinds of falls. We evaluated all patients with facial injuries due to stumbling or falls who presented to Besat Hospital in Hamedan, Iran, during the 2.5-year study period and analyzed the acquired data. Of 2990 patients with facial injuries who were referred to Besat Hospital during the study period, 733 (24.5%) were injured by stumbling, and 246 (8.2%) were injured by falls. ⋯ The rate of associated injuries in falls was higher than stumbling accidents. We concluded that the incidence, age distribution, rate, and pattern of bone fractures and the frequency and type of associated injuries in stumbling accidents were significantly different from that of fall accidents. For a good program planning to prevent and manage facial injuries, we recommend separate evaluation of stumbling and fall accidents.

Diabetes mellitus can cause various diseases, including loss of bone mineral density as a characteristic manifestation of osteoporosis. In this condition, bone is more vulnerable to pathologic fractures that can be treated by implantation of biomaterial grafts. The aim of this study was to evaluate the osteogenic capacity of hydroxyapatite implanted into bone defects in the skull of nonobese diabetic mice. ⋯ The quantity of newly formed bone was significantly higher (P < 0.05) than that observed in the diabetic groups. The recipient area of diabetic groups contained a larger amount of connective tissue as demonstrated by radiographic analyses. In conclusion, the osteogenesis guided by the properties of hydroxyapatite may even occur in bone suffering from the effects of diabetes, but the quantity of newly formed bone is lower, and the process is slower.

Neurofibromatosis type 1, an autosomal dominant inherited disease, presents pathologic symptoms of multiple systems, including neurofibromatosis, skeletal dysplasia, café-au-lait spots in skins, and so on. A 45-year-old man with neurofibromatosis type 1 was reported in this article. The patient presented a giant neurofibroma in his head and neck, dysplasia of skull, facial bones and spinal columns, and multiple café-au-lait spots in systematic skins. Satisfactory curative effects were obtained in this case after tumor resection and prosthesis implantation.

Treatment of microstomia, whether congenital or acquired, has long challenged the ingenuity of surgeons. In all instances, the challenge remains the ability to preserve function and provide and maintain reasonable aesthetics. The following case report presents 2 different cases of surgical correction of microstomia, resulting from flap reconstructions after perioral tumor surgery. ⋯ Results have shown that, with the use of our fishtail design, we can restore the unique architecture of the oral commissure with the postoperative intercommissural distance improved by more than 10 mm and the interincisal width enlarged by approximately 5 mm. Our solution was functional and aesthetically acceptable, as well as simpler and cheaper, in comparison with the traditional surgical methods that are usually expensive, complex, and less practical. We believe that, in cases in which either the contracture is mild or a commissurotomy can be expected to increase the width and the general size of the oral aperture, this relatively conservative technique, if judiciously used, can be performed with ease and safety with good results.
