CBCT appraisal of anatomical landmarks used in Vazirani-Akinosi nerve block technique.

Objectives: The aim of this cross-sectional study was to assess the proximity of maxillary second molar (MSM) and maxillary tuberosity (MT) to mandibular foramen (MF) to perform successful Vazirani-Akinosi nerve block (VANB) technique.

Methods: Cone beam computed tomography (CBCT) images of 2613 sides of the jaw were selected for the study. The vertical distance from MSM to the MF and the vertical distance from MT to the MF and from MT to the posterior border of the ramus (PR) were measured and compared between males and females using independent samples t test.
