The IOF is located in close proximity to vital anatomical structures; therefore proper identification of its location during regional block anesthesia is highly recommended [3, 4].
An additional aim was to determine the depth of needle penetration into pterygopalatine fossa through GPC to help dentists avoid serious complications following regional block anesthesia. The hard palate approximately forms a 60[degrees] angle with GPC [16] and the patient is usually seated in a semi-reclined position with the mouth opened and head tilted back.
Therefore, proper identification of the location of IOF and pterygopalatine fossa is highly recommended during regional block anesthesia and surgical procedures, due to the close proximity to vital anatomic structures.
However, to date there has been no published literature examining the relationship between postoperative range of motion and function with the presence or absence of regional block anesthesia.
The purpose of this study was to examine the functional outcome following ORIF of a displaced proximal humerus fracture in patients who received regional block anesthesia via a brachial plexus interscalene block compared to those who had general anesthesia for their surgery.
Five patients (11.1%) within the regional block anesthesia group experienced a postoperative complication.
