An intraoral approach is possible but technically more difficult as the
surgeon will need several sets of trained hands just to retract the soft
tissues of the cheeks and tongue. Additionally, stabilization and fixation of
the fractures is much more difficult via an intraoral approach. One should also
be aware that the inferior alveolar nerve is located on the superior surface of
the atrophic mandible. Therefore one must be extremely careful making intraoral
incisions to expose atrophic fractures, or the nerve can be damaged.
