Direct skeletal traction for Le Fort I halo distraction replacing an intraoral dental splint and connecting traction hook.

Abstract

To obviate dental inconveniences after Le Fort I halo distraction using an intraoral dental splint and connecting traction hook, the authors initiated direct skeletal traction using an traction wire at the parapyriformis buttress area. Halo distraction using this procedure was conducted for 11 cleft lip and palate patients (age range, 13-21 years; 6 females and 5 males). Distraction amount ranged from 11 to 15 mm. A satisfactory occlusion was obtained in all patients. All 11 patients complained of pain during the distraction period, but it was controlled by regular oral intake of the usual amount of analgesics. No other particular complications were encountered during the postoperative follow-up of 8 to 18 months. This form of direct skeletal traction proves effective for Le Fort I halo distraction.
