The Zurich Pediatric Maxillary Distractor

 

 Intraoperative Approach



A high LeFort I Osteotomy is performed avoiding damage to non erupted teeth, especially the high positioned canine.

The pterygoid process is separated from the maxillary tuberosity as well as from the nasal septum.

The maxilla is gently mobilized without down fracturing.

Bone is removed at the zygomatic buttress for proper placement of the distraction device.

The distractor is opened slightly more than the desired amount of maxillary advancement and then adapted to the bone surface of the zygoma and the alveolar process.

By turning the flexible activator with the patient-screwdriver clockwise the distractor is closed and the maxilla moves forward.

Following a 3-5 day latency period distraction proceeds at a rate of 0.5mm to 1mm per day on each side of the maxilla.
