Introduction: The standard Keen's or the maxillary vestibular incision allows direct access to the zygomatico-maxillary complex with inadvertent transection of the facial muscles and more laborious visualisation of the zygoma.
Materials and methods: We describe modifications to the vestibular and Keen's technique, based on identification and re-orientation of the facial muscles as well as utilisation of anatomical gaps between the facial mimetic muscles.
Conclusion: Our modifications are based on the principle of facial mimetic muscle identification, preservation and re-orientation to near normal anatomy.
Keywords: Facial muscles; Modified Keen’s approach; Modified maxillary vestibular approach; Zygoma.
