Figure 3.
(A) Separation of the medial canthus does not occur in medial maxillary (nasomaxillary buttress) fracture because a ligament-attached bone fragment (●) is deviated inside and/or toward the middle with the maxillary frontal process due to an external lateral force. (B) In NOE fracture, separation of the medial canthus occurs because of an external force from the front. NOE = naso-orbito-ethmoidal.
