Objective Assessment of stability of the advanced maxilla after two-jaw surgery and Le Fort I osteotomy in patients with cleft palate based on soft tissue planning. Subjects Between 1995 and 1998, 15 patients with cleft lip and palate deformities underwent advancement of a retruded maxilla, without insertion of additional bone grafts. Eleven patients had bimaxillary osteotomies and four patients only a Le Fort I osteotomy. Relapse of the maxilla in horizontal and vertical dimensions was evaluated by cephalometric analysis after a clinical follow-up of at least 2 years. Results In the bimaxillary osteotomies, horizontal advancement was an average 4 mm at point A. After 2 years, there was an additional advancement of point A of an average of 0.7 mm. In the mandible, a relapse of 0.8 mm was seen after an average setback of 3.9 mm. In the four patients with Le Fort I osteotomy, point A was advanced by 3.8 mm and the relapse after 2 years was 0.9 mm. Vertical elongation at point A resulted in relapse in both groups. Impaction of the maxilla led to further impaction as well. Conclusion Cephalometric soft tissue analysis demonstrates the need for a two-jaw surgery, not only in severe maxillary hypoplasia. Alteration of soft tissue to functional harmony and three-dimensional correction of the maxillomandibular complex are easier to perform in a two-jaw procedure. It results in a more stable horizontal skeletal position of the maxilla.

The aim of this study is to evaluate Le Fort I Osteotomy and zygomatic implantation without any graft placement for management of a cleft lip and palate patient. This case report describes oral rehabilitation of a 33-year-old patient with bilateral cleft lip-palate and oronasal fistula and atrophic pre-maxilla. As treatment, the patient received simultaneous Le Fort I osteotomy, palatoplasty and two zygomatic implant insertions. The prosthetic superstructure included zygomatic implant-supported removable hybrid prosthesis on bar locator and metal-ceramic fixed bridges in the posterior region. As conclusion, this protocol can be promising for management of patients with cleft lip-palate and malocclusion.

Le Fort I

Objective: Diminished maxillary growth is a consequence of labiopalatal repair, and many patients with cleft lip and palate require Le Fort I advancement. The goal of this study was to determine the frequency of maxillary hypoplasia as measured by need for Le Fort I. Subjects: Retrospective cohort study of males born before 1987 and females before 1989. Records of 173 patients with cleft lip and palate and 34 with cleft palate were reviewed. Methods: Documented age, gender, cleft type, and need for Le Fort I. Pearson chi-square and Fischer's exact analyses were performed to evaluate the frequency of Le Fort I. Results: Of 217 patients with cleft lip and palate or cleft palate, 40 were syndromic; of the remaining 177 patients, 69 had cleft lip, 78 had cleft lip and palate, and 30 had cleft palate. Thirty-seven of 177 patients (20.9%) required Le Fort I, subcategorized by cleft type: 0/69 for cleft lip, 37/78 for cleft lip and palate, and 0/35 for cleft palate (p < .0001). Of the 37/78 (47.4%) cleft lip and palate patients, the frequency of Le Fort I correlated with severity: 5/22 unilateral incomplete cleft lip and palate; 16/33 unilateral complete cleft lip and palate; 1/2 bilateral incomplete cleft lip and palate; 2/4 bilateral asymmetric complete/incomplete cleft lip and palate; 13/17 bilateral complete cleft lip and palate (p < .05). Conclusion: Overall frequency of Le Fort I was 20.9% in patients with cleft lip and palate and cleft palate. Of those with cleft lip and palate, 47.7% required maxillary advancement, but none with isolated cleft lip or cleft palate required correction. Frequency of Le Fort I osteotomy correlated with the spectrum of severity of labiopalatal clefting.

Objective: This study aimed to evaluate the Le Fort I osteotomy line and pterygomaxillary junction via cone-beam computed tomography in individuals with cleft lip and palate (CLP). Design: Retrospective study. Patients and Methods: The study included individuals older than 16 years with CLP, who were scheduled for repositioning of the maxilla by Le Fort I osteotomy, and those with class III malocclusion with maxillary hypoplasia, who were scheduled for Le Fort I osteotomy. The measurements made in the area of the cleft of individuals with CLP were compared with both the side with no cleft and those with class III malocclusion with maxillary hypoplasia. A total of 11 measurements were made on the axial section parallel to the Frankfurt Horizontal plane, corresponding to the lower 1/5 of the distance between the infraorbital foramen and the anterior nasal spine. Results: There were significant differences both in the comparisons made between the individuals with CLP and those without CLP in terms of the canal-anterior alveolar crest (G) and sinus-anterior alveolar crest (L) measurements ( P < .05). The mean measurement values showed that the measurement results were higher in individuals with CLP in general. Conclusion: In conclusion, we believe that there might be difficulties both in osteotomy and down fracture stages during Le Fort I osteotomies performed in individuals with CLP.
