Coronal approach

Examples of extentions

If the zygomatic arch is to be exposed, a pre- (A) or postauricular extension has to be added. The extension behind the ear may follow the helical fold (B) or the hairline (C).

If the temporomandibular joint area will be accessed, a preauricular extension down to the level of the earlobe is necessary.
