“…ethmoidal nerve before reducing nasal fractures of people has been reported to be effective in reducing postoperative pain. 17 Our technique of perineural injection of the ethmoidal nerve, using 0.5 mL of dye, although not always accurate, proved to be reliable (90% incidence of perineural deposition). Injecting a larger volume of local anesthetic solution, such as 5 mL, would likely compensate for slight inaccuracy of this technique.…”

“…However, when anesthetizing the infraorbital nerve did not provide complete desensitization, anesthetizing the external nasal branch of the ethmoidal nerve added substantially to desensitization . Anesthetizing the anterior ethmoidal nerve before reducing nasal fractures of people has been reported to be effective in reducing postoperative pain …”

“…The experimental results revealed an increased number of total activity counts one week postoperatively for the rabbits that received the 3D printed cage when compared to those without the cage. These results indicated better bony fragments stabilization with less fracture pain due to fragmental irritations of the periosteum [ 20 ]. The imaging examination results showed less anterior cortical bone breakage one week postoperatively.…”

This study aimed to develop a new biodegradable polymeric cage to convert corticocancellous bone chips into a structured strut graft for treating segmental bone defects. A total of 24 adult New Zealand white rabbits underwent a left femoral segmental bone defect creation. Twelve rabbits in group A underwent three-dimensional (3D) printed cage insertion, corticocancellous chips implantation, and Kirschner-wire (K-wire) fixation, while the other 12 rabbits in group B received bone chips implantation and K-wire fixation only. All rabbits received a one-week activity assessment and the initial image study at postoperative 1 week. The final image study was repeated at postoperative 12 or 24 weeks before the rabbit scarification procedure on schedule. After the animals were sacrificed, both femurs of all the rabbits were prepared for leg length ratios and 3-point bending tests. The rabbits in group A showed an increase of activities during the first week postoperatively and decreased anterior cortical disruptions in the postoperative image assessments. Additionally, higher leg length ratios and 3-point bending strengths demonstrated improved final bony ingrowths within the bone defects for rabbits in group A. In conclusion, through this bone graft converting technique, orthopedic surgeons can treat segmental bone defects by using bone chips but with imitate characters of structured cortical bone graft.

“…The local nerve block seemed to improve pain control under anesthesia in combination with lidocaine/fentanyl CRI. Local nerve blocks are commonly used in human medicine for surgical procedures on the mandible and maxilla and they have been shown to improve postoperative pain management [6, 24, 25, 31–33]. The increasing use of swine models for oral and maxillofacial surgical research justifies further investigation into the effectiveness of local nerve blocks.…”

Purpose/Aim The primary objective was to evaluate the effect of a bupivacaine mandibular nerve block on intraoperative blood pressure (BP) and heart rate (HR) in response to surgical stimulation and the need for systemic analgesics postoperatively. We hypothesized that a mandibular nerve block would decrease the need for systemic analgesics both intraoperatively and postoperatively. Materials and Methods Fourteen adult male Yucatan pigs were purchased. Pigs were chemically restrained with ketamine, midazolam, and dexmedetomidine and anesthesia was maintained with isoflurane inhalant anesthesia. Pigs were randomized to receive a mandibular block with either bupivacaine (bupivacaine group) or saline (control group). A nerve stimulator was used for administration of the block with observation of masseter muscle twitch to indicate the injection site. Invasive BP and HR were measured with the aid of an arterial catheter in eight pigs. A rescue analgesic protocol consisting of fentanyl and lidocaine was administered if HR or BP values increased 20% from baseline. Postoperative pain was quantified with a customized ethogram. HR and BP were evaluated at base line, pre-rescue, 10 and 20 min post-rescue. Results Pre-rescue mean BP was significantly increased (p = .001) for the bupivacaine group. Mean intraoperative HR was significantly lower (p = .044) in the bupivacaine versus saline group. All other parameters were not significant. Conclusion Addition of a mandibular nerve block to the anesthetic regimen in the miniature pig condylectomy model may improve variations in intraoperative BP and HR. This study establishes the foundation for future studies with larger animal numbers to confirm these preliminary findings.
