In some cases, the surgeon may consider taking dental impressions, making
dental models, and from these models making a palatal splint. Such a splint
will support soft-tissue healing in the palate. The palatal splint is then
wired to the dentition also possibly using arch bars. Depending on the
stability of the palatal unit, as well as other complicating issues regarding
other midface fractures and postoperative airway, the surgeon may choose to
leave the patient in postoperative MMF.
In cases where there has been splaying of the palate, cuts are made in the
maxillary portion of the dental model, along the line of the palatal fracture,
with repositioning of the maxillary model to determine the premorbid contour of
the maxillary arch. This is accomplished using the mandibular impression. Once
the maxillary model has been adjusted to its premorbid shape, the palatal
splint is made with the use of this maxillary model.
