ABSTRACT
BACKGROUND: The authors have recently reported on the use of an internal maxillary distraction device. In this study, we report on the hard and soft tissue movements achieved with this intraoral distraction device, and the stability changes after distraction osteogenesis for maxillary hypoplasia in patients with cleft lip and palate. METHODS: Ten male patients with severe hypoplasia of the maxilla, with complete uni- or bilateral cleft lip and palate were included. The mean age of the patients at the time of operation was 11.91 years (±3.41). To evaluate the distraction process and stability, superimpositions on the preoperative lateral cephalograms were performed. The mean follow-up (FU) was 15.42 months (±3.94). RESULTS: Cephalometric measurements at all of the maxillary hard and soft tissue points improved significantly. Maxillary point A was advanced by 8.25 mm (±3.17; P < 0.001). After distraction soft tissue point A' had advanced 7.10 mm (±2.69; P < 0.001). The soft tissue to hard tissue ratio at point A was 0.86:1 after distraction. Maxillary horizontal relapse at point A was 14.1% at FU. Vertical relapse was not significant. CONCLUSION: This rigid intraoral distraction device can be successfully used in the correction of severe maxillary hypoplasia. The marked aesthetic improvement and low psychological encumbrance make this device viable for the treatment of cleft-related hypoplasia of the maxilla.

In hemifacial microsomia, patients with severely hypoplastic mandibles (Pruzansky type III) require replacement of the ramus and condyle unit. Common complications of this procedure include graft fracture and overgrowth of the graft. An uncommon case of osteolysis of the costochondral graft with osteitis of the middle cranial fossa is reported herein. To our knowledge, no such case has been reported in the literature previously. The aim of this report is to present the only known case and to discuss the contributing factors.

Maxillary distraction osteogenesis is well established for the treatment of severe retromaxilla. We report our experience since 2004 of the treatment of 19 patients using a new intraoral maxillary distraction device. Maxillary advancement was successful in all patients with mean advancement of 9.6mm (range 4-17) measured at a point in lateral cephalograms. The new device limited surgical exposure and the amount of materials implanted, and improved control in every phase of the distraction. It was psychologically accepted by patients and was more comfortable than existing devices.

The treatment of Cyrano nose haemangioma (CNH) is difficult because of its location and possible complications: psychological impact, severe skin infiltration and consequences on nasal growth. We suggest that the best treatment for nasal tip haemangiomas is an early surgery to remove the affected tissues and preserve the anatomy. A total of 39 children (32 females and seven males) underwent early surgery for the treatment of CNH. Mean age was 35 months. Skin infiltration was present in 15 cases. Cartilage lack or distortion was observed in 29 cases. Each patient was evaluated for global cosmetic appearance, reduction in volume of the tumour, improvement of skin texture and quality of the scar. Multiple surgical procedures were performed in 14 cases. The average postoperative follow-up was 48 months. Patients with low-volume tumours had only one surgery, whereas patients with large tumours underwent a mean of 1.9 surgeries. In 29 cases, distortion or lack of cartilaginous structures required dissection and approximation of the alar cartilages in their anatomical position. We could identify three types of CNH that lead to three distinct surgical approaches: type A (mild cases) is characterised by no cutaneous involvement, no misalignment of the cartilages and mild nasal volume increase; type B (moderate cases) entails partial cutaneous infiltration, misalignment of the cartilages and moderate nasal volume increase; and type C (severe cases) is characterised by cutaneous infiltration, misalignment of the cartilages and severe nasal volume increase.
