Observation is reserved for non- or minimally-mobile Le Fort I fractures with unaffected occlusion. The patient is advised to stay on a soft diet for several weeks. The maxilla should become firm, at which point the diet can be advanced as tolerated.
Observation implies close follow-up. A common sequela to this treatment, is a malocclusion resulting from minimal displacement escaping clinical detection.

For aftercare and rehabilitation following observation, please refer to your local protocol.
