Efficacy of greater auricular nerve block in eliminating pain during mandibular third molar extraction.
Pak Oral Dental J Jan ;35(4):574-7.

Pain during mandibular third molar tooth surgery following conventional inferior alveolar nerve block (IANB) is quite common because of sub-optimal analgesia. A double- blind randomized controlled trial was done to evaluate the efficacy of extraoral greater auricular nerve block (GANB) as preemptive analgesia in patient undergoing surgical extraction of mandibular third molar class 2, 3 position B and C. This Study was conducted in minor oral surgical department at Armed Forces Institute of Dentistry from 6th Aug, 2012 to, 5th Feb 2014. A total of sixty patients were divided into two equal groups. Group A received conventional IANB along with GANB while group B was administered IANB only. In group A, 23(76.7 %) patients experienced no pain while only 7(23.3 %) patients experienced mild pain. While in group B, 6(20.0%) patients experienced no pain, 22(73.3%) experienced mild pain, 2(6.7 %) patients experienced moderate pain. The difference was statistically significant (p-value0.0001).Based on this study it was concluded that perioperative pain can be eliminated by preemptive GANB analgesia in deep seated mandibular third molar extractions.
