Objective: To evaluate the long-term stability of LeFort I osteotomy followed by distraction osteogenesis with a transcutaneous rigid external device for the treatment of severe maxillary hypoplasia in patients with cleft lip and palate. Patients and Methods: Nine patients with cleft lip and palate underwent rigid external distraction after a LeFort I osteotomy for maxillary advancement. Lateral cephalometric films were analyzed for assessment of treatment outcome and stability in 1 month, 6 months, and 1 year after distraction. Results: Significant maxillary advancement was observed in the horizontal direction, with the anterior nasal spine (ANS) distance of the maxilla increasing by an average of 20.5 ± 5.1 mm after distraction. The ANS relapse rates in 6 months and 1 year were 8.7% and 12.8%, respectively. The mean inclination of upper incisors to the palatal plane was almost unchanged (before: 109.8° ± 6.6°; after: 108.9° ± 7.5°). The movement ratios at the nasal tip/ANS, soft tissue A point/A point, and the upper vermilion border/upper incisor edge were 0.36:1, 0.72:1, and 0.83:1, respectively. Conclusion: Considerable maxillary advancement was achieved with less change of incisors inclination after distraction. Moreover, the relapse rate after 1 year was minimal. The concave facial profile was improved as well as the facial balance and aesthetics.

ABSTRACT Objectives: This study evaluated the long-term stability of maxillary protraction (MP) in patients with complete unilateral cleft lip and palate (UCLP) and identified factors influencing relapse and long-term outcomes. Materials and Methods: Twenty-three adolescents with UCLP who underwent MP therapy were recalled when craniofacial growth was close to completion. Subjects exhibiting reverse/positive overjets were assigned to unstable/stable groups. Lateral cephalometric measurements were made before treatment (T0), after active treatment (T1), and at the end of the growth spurt (T2). Results: About 63% of the subjects exhibited positive overjets during follow-up. The unstable group demonstrated higher B–x and Co–Gn distances than the stable group (both P < .05) at T0. More short-term (T0–T1) sagittal advancement of point A (A–y) was evident in the unstable group than in the stable group (P < .05), but no long-term difference was apparent between the two groups (P = .481). During the posttreatment period (T1–T2), the SNA angle and maxillary incisor protrusion (U1–SN angle) were considerably lower in the unstable group than in the stable group (both P < .05). Overall, the unstable group exhibited a lower increase in the vertical extent of point A (A–x) than the stable group from T0 to T2 (P < .05). Conclusions: In the long term, MP affords favorable maxillary advancement in patients with UCLP. A mandibular excess at T0 and vertical maxillary hypoplasia may contribute to the long-term relapse of a reverse overjet.

This case report demonstrates the successful use of intraoral distractor/hygenic rapid expander (HYRAX) for rapid maxillary expansion in anteroposterior direction with an adjunctive use of face mask therapy for anterior orthopedic traction of maxillary complex in a cleft patient with concave profile. The patient was a 13-year-old girl who reported with a chief complaint of backwardly positioned upper jaw and a severely forward positioned lower jaw. Therefore, a treatment was chosen in which acrylic bonded rapid maxillary expansion was done with tooth tissue borne intraoral distractor/HYRAX having a different activation schedule along with Dr Henri Petit facemask to treat maxillary retrognathism. As a result, crossbite got corrected and attained a positive jet with no bone loss in cleft area over a period of 5 months which was followed by fixed mechanotherapy achieving a well settled occlusion in 1 year. After completion of expansion and fixed mechanotherapy, ANB became +1 post-treatment which was −4 pretreatment. The prognathic profile was markedly improved by expansion and taking advantage of the remaining growth potential, thus minimizing the chances of surgery later in life. This provided a viable alternative to orthognathic surgery with good long-term stability.
