A new method of continuous maxillary nerve block with an indwelling catheter.
We describe continuous maxillary nerve block at the pterygopalatine fossa and investigate the efficacy of this technique for perioperative pain control in oral surgery. ⋯ Indwelling maxillary nerve catheter methods decrease anesthetic consumption and provide good postoperative analgesia.

Mandibular nerve block at the oval foramen using reliable landmarks: refinement of a previously described procedure.
The aim of this study was to improve the injection technique when blocking the mandibular nerve at the oval foramen by using consistent landmarks. The lower lateral orbital angle (LLOA) and the junction of the external acoustic canal and the mastoid process (AM) proved to be reliable landmarks. Distances between landmarks for the localization of the puncture point (PP), cranial indices as well as the angle of the injection needle to the sagittal plane were calculated on 22 human dried skulls. ⋯ The angle of the injection needle to the sagittal plane was 71.86 degrees. No correlation was found between the cranial index and the angulation of the needle or the distances for the localization of the PP. From this study a modified puncture technique was developed.

Comparative Study
Sciatic nerve block with bupivacaine-loaded microspheres prevents hyperalgesia in an inflammatory animal model.
The aim of this study was to evaluate the effect of different durations of local anesthetic neural blockade on hyperalgesia after carrageenan infiltration in a rat model. ⋯ B-Ms as a drug delivery system prolongs the duration of neural blockade and avoids hyperalgesia phenomena in this rat model of inflammation.
