Fifty-four injection injuries in 52 patients were caused by mandibular block analgesia affecting the lingual nerve (n=42) and/or the inferior alveolar nerve (n=12). All patients were examined with a standardized test of neurosensory functions. The perception of the following stimuli was assessed: feather light touch, pinprick, sharp/dull discrimination, warm, cold, point location, brush stroke direction, 2-point discrimination and pain perception. ⋯ Unlike most mechanical injuries after surgery, injection injuries were not followed by a course of spontaneous improvement of neurosensory and/or gustatory function. This may indicate neurotoxicity as a central aetiological factor. Fifty-four percent of the nerve injuries were associated with Articaine 4%, and a substantial increase in the number of injection injuries followed its introduction to the Danish market.

Randomized Controlled Trial Comparative StudyA prospective comparison of octyl-2-cyanoacrylate and suture in standardized facial wounds.
Regarding the cosmetic results of wound closure using tissue adhesives as opposed to sutured wounds, most published studies are performed on children and with non-standardized lacerations, which makes it difficult to transfer the results to facial incisional wounds in adults. There are also conflicting conclusions about the cosmetic results. The purpose of this randomized prospective study was to compare the cosmetic outcomes of wound closure with sutures and octyl-2-cyanoacrylate in standardized facial wounds in adults. ⋯ There were no differences in the overall cosmetic results among all patients in the two groups. Interestingly, in the younger patients the result of the sutured wounds was superior to that of the adhesive-treated patients. The Dermabond skin adhesive provides a means of closure of facial surgical wounds without early complications, but adjustment of the edges of the wound and the cosmetic result in younger patients are less successful than with thin sutures.

Comparative StudyThe role of intraoperative ultrasonography in zygomatic complex fracture repair.
Intraoperative assessment of the zygomatic arch is very important in achieving adequate repositioning. The correct alignment of the zygomatic arch indicates the proper position of the zygomatic bone and ensures adequate prominence of the lateral midfacial aspect. The aim of this study was to estimate the value of ultrasonography as an intraoperative repositioning control. ⋯ The ultrasound images were concordant with the radiographs. Clinical assessment by palpation only succeeded in isolated zygomatic arch fractures with an m-shaped impression, whereas it remained uncertain in nearly all cases with a different dislocation pattern. Ultrasonography was rapid and easy to perform, and is recommended as an intraoperative visualizing tool in all midfacial fractures with displacement of the zygomatic arch.

Randomized Controlled Trial Comparative StudyA comparison of post-operative complications following wisdom tooth surgery performed with sterile or clean gloves.
This randomised prospective study aimed at evaluating possible differences in the post-operative complication rate following lower wisdom tooth surgery performed with either sterile or clean surgical gloves. The microbiological profiles of the tooth sockets and glove surfaces were also evaluated and compared. A total of 275 ASA I, non-smoking and non-drinking patients consented to be randomly assigned into two groups for lower wisdom tooth surgery, performed by operators wearing either sterile or clean gloves. ⋯ The total number of colony forming units and the variety of bacterial isolates from the socket wounds in the sterile and clean glove groups were similar. The study concluded that there was no advantage in using sterile surgical gloves rather than clean gloves to minimize post-operative complications in wisdom tooth surgery. There was also no apparent relationship between the bacteria contaminating the clean glove surfaces and those isolated from the socket wounds.

Comparative StudyA comparison of brachytherapy and surgery for the treatment of stage I-II squamous cell carcinoma of the tongue.
The treatment method for early stage tongue cancer is still controversial in Japan. The aim of this study is to compare the prognosis for patients with early tongue cancer treated with brachytherapy and surgery. A retrospective study was conducted to compare the efficacy of low-dose-rate brachytherapy (LDR), high-dose-rate brachytherapy (HDR), and surgery for early tongue cancer. ⋯ Neck failure was recorded for eight patients in the LDR, six in the HDR, and three in the surgery group. The respective 5-year overall survival rates for the LDR, HDR and surgery groups were 84.0%, 72.9%, 95.4% for stage I, and 72.2%, 51.5%, 93.8% for stage II. These findings show that surgery is the optimal treatment method for patients with stage I-II tongue cancer.
