Randomized Controlled Trial Comparative Study
Comparison of different administration of ketamine and intravenous tramadol hydrochloride for postoperative pain relief and sedation after pediatric tonsillectomy.
Tonsillectomy is the oldest and most frequently performed surgical procedure practiced by ear, nose, and throat physicians. In this study, our aim was to compare the analgesic effects of peritonsillar, rectal, as well as intravenous infiltration of ketamine and intravenous tramadol hydrochloride infiltration for postoperative pain relief and sedation after tonsillectomy in children. ⋯ Perioperative, low-dose IV, rectal, or peritonsillar ketamine infiltration provides efficient pain relief without any adverse effects in children who would undergo adenotonsillectomy.

Randomized Controlled Trial
Remifentanil, ketamine, and propofol in awake nasotracheal fiberoptic intubation in temporomandibular joint ankylosis surgery.
Nasotracheal intubation of patients with temporomandibular joint (TMJ) ankylosis is a challenge for anesthesiologists. Awake fiberoptic intubation (AFOI) is the safest technique in patients with difficult airway. This study compares 3 different techniques of conscious sedation during AFOI in patients with TMJ ankylosis. ⋯ Remifentanil was the best agent for AFOI, because it provided shorter intubation time, better intubation conditions, and least patient's complaint.Iranian registry no.: IRCT 201208061674N4 (www.irct.ir).

Comparative Study
Evaluating the safety and efficacy of tranexamic acid administration in pediatric cranial vault reconstruction.
Blood loss is the leading cause of mortality after major craniofacial surgery. Autologous blood donation, short-term normovolemic hemodilution, and intraoperative blood salvage have shown low efficacy in decreasing transfusions. Tranexamic acid (TXA) is a synthetic antifibrinolytic drug that competitively decreases the conversion of plasminogen to plasmin, thereby suppressing fibrinolysis. The purpose of this study was to investigate the impact that TXA administration has on intraoperative blood loss and blood product transfusion in pediatric patients undergoing cranial vault reconstruction. ⋯ The use of TXA in pediatric cranial vault reconstruction significantly reduces perioperative blood loss and blood product transfusion requirements. The TXA administration is safe and may improve patient outcomes by decreasing the likelihood of adverse effects related to blood product transfusion.

Comparative Study
The diagnosis and surgical treatment of central brain herniations caused by traumatic bifrontal contusions.
The objective of this study was to investigate the diagnosis and surgical treatment of central brain herniations caused by traumatic bifrontal contusions. A total of 63 patients (45 men and 18 women; mean age of 43 years with a range from 20 to 72 years) who suffered from traumatic bifrontal contusions between January 2007 and December 2012 were inspected. The clinical and imaging results were studied for all patients, and we found that swelling of the mesencephalon and a downward shift of the bilateral red nucleus were significant signs of central brain herniation in the image of magnetic resonance imaging. ⋯ The Glasgow Outcome Scale was used to monitor the patients during the follow-up period, which lasted from 6 to 52 months with a mean of 22 months. At the termination of the follow-up period, the following Glasgow Outcome Scale scores were obtained: 14 patients scored 5 points, 22 patients scored 4 points, 7 patients scored 3 points, 13 patients scored 2 points, and 7 patients scored 1 point. Therefore, our study suggested that an early magnetic resonance imaging scan could result in a more timely diagnosis of central brain herniation, and simultaneous bilateral craniotomy was found to be one of the best treatments for central brain herniation to improve patient outcomes.

Comparative Study
Attachment rate of the inferior alveolar nerve to buccal plate during bilateral sagittal split osteotomy influences self-reported sensory impairment.
This study was aimed to investigate a modified buccal osteotomy technique and whether the integrity of the lingual part of the lower border influences the attachment of the neurovascular bundle to the proximal segment of the mandible during a sagittal split osteotomy without increasing the number of bad splits. The presence of self-reported sensibility disturbance in the lower lip at the last follow-up visit was assessed. This study included 220 and 133 patients with bilateral sagittal split osteotomy undergoing the classical and the new modified buccal osteotomy techniques, respectively. ⋯ In the classical technique, the inferior alveolar nerve was attached to the proximal segment of the mandible in more than one third of operation sites (36.36% on the right and 40.91% on the left) compared with less than one fourth of the operation sites using the new technique (9.73% on the right and 23.01% on the left). The overall figure of self-reported changed sensibility was 09.40% (12/128) in the new technique compared to 15.12% in the classical technique. We present a suitable improvement to the classical buccal osteotomy technique that allows less manipulation and injury of the inferior alveolar nerve with consequent reduction in self-reported postoperative changes in lower lip sensation
