OBJECTIVES: To describe the surgical orthodontic technique of correcting transverse maxillary deficiency associated with nasal obstruction and malocclusion.
SURGICAL PROCEDURE: The surgical-orthodontic correction of transverse maxillary deficiency consists in an incomplete Le Fort I procedure, without down-fracture, associated with a sagittal palatal osteotomy. This procedure is called SARE (Surgically Assisted Rapid Expansion). A pre-fabricated orthodontic appliance is cemented to premolars and molars prior to the surgical procedure. The patient activates the appliance allowing a 1 mm widening a day up to 10 mm. A stabilisation phase is mandatory to avoid early relapse of the correction. This phase involves ossification of the midline osteotomy site.
RESULTS: A 22 year old female consulted for a chronic nasal obstruction. Previous treatments, medical and surgical (septoplasty) did not improve her symptoms. She presented with a typical transverse maxillary hypoplasia. She underwent a surgery with the technique described above. Nasal patency improvement was noted on the first post-operative day. This was confirmed by comparing pre and post-operative rhinomanometry. An orthodontic treatment followed for several months to stabilize the result.
DISCUSSION AND CONCLUSION: Main advantages of this surgical intervention are to correct both the dental malocclusion and the nasal obstruction by widening the nasal floor and the maxillary arch. Post-operative period is mostly uneventful. It can take up to six months to achieve a good result that is why a strong collaboration has to exist between the surgeon, the orthodontist and the patient.
