Traditionally, maxillary hypoplasia in the setting of cleft lip and palate is treated via orthognathic surgery at skeletal maturity, which condemns these patients to abnormal facial proportions during adolescence. The authors sought to determine the safety profile of computer-aided design/computer-aided modeling (CAD/CAM) planned, Le Fort I distraction osteogenesis with internal distractors in select patients presenting at a young age with severe maxillary retrusion. The authors retrospectively reviewed our "early" Le Fort I distraction osteogenesis experience-patients performed for severe maxillary retrusion (≥12 mm underjet), after canine eruption but prior to skeletal maturity-at a single institution...

Primary repair of cleft lip and palate occurs early in life, but ideal timing of these interventions remains controversial. Prior research has indicated that a later palate repair may improve patients' midfacial growth long term, whereas optimal timing of lip repair to maximize midfacial growth has not been identified.The purpose of this study is to analyze a large, diverse cohort of patients with cleft lip and palate to determine whether timing of primary palate repair and primary lip repair contributed significantly to subsequent orthognathic surgery...

The purpose of this study was to investigate the amount and pattern of postsurgical relapse after 2-jaw surgery in cleft lip and palate patients in terms of the sagittal and vertical aspects. The samples consisted of 21 adult patients who had the similar initial skeletodental pattern before surgery and underwent 2-jaw surgery. They were divided into high relapse (n = 11) and low relapse groups (n = 10) (criteria, 30% forward relapse of the B point). After the cephalometric variables of cephalograms taken at 1 month before surgery (T0), immediately after surgery (T1), and at least 1 year after surgery (T2) were measured, the Wilcoxon test, Mann-Whitney U test, and Pearson correlation test were performed for statistical analysis...

INTRODUCTION: Computer-assisted preoperative simulation surgery is employed to plan and interact with the 3D images during the orthognathic procedure. It is useful for positioning and fixation of maxilla by a plate. We report a case of maxillary retrusion by a bilateral cleft lip and palate, in which a 2-stage orthognathic procedure (maxillary advancement by distraction technique and mandibular setback surgery) was performed following a computer-assisted preoperative simulation planning to achieve the positioning and fixation of the plate...

BACKGROUND: Cleft lip and palate is one of the most common birth defects and can cause difficulties with feeding, speech and hearing, as well as psychosocial problems. Treatment of orofacial clefts is prolonged; it typically commences after birth and lasts until the child reaches adulthood or even into adulthood. Residual deformities, functional disturbances, or both, are frequently seen in adults with a repaired cleft. Conventional orthognathic surgery, such as Le Fort I osteotomy, is often performed for the correction of maxillary hypoplasia...

INTRODUCTION: Treatment of cleft lip and palate patients requires a multidisciplinary plan. These patients usually have a hypoplastic maxilla due to the prior surgical scars. Orthognathic surgery to advance the maxilla in these patients is not very efficient; therefore, orthopedic interventions during an appropriate age seems to be essential. CASE REPORT: In this article, two cleft lip and palate patients have been treated with Class III elastics anchored to the maxillary posterior and mandibular anterior miniplates in order to induce maxillary advancement...

BACKGROUND: Cleft lip and palate patients present large osseous defects of the alveolus and midface hypoplasia. Traditional orthognathic surgery has limitations of relapse and limited age group. Distraction osteogenesis (DO) as a modality for midface advancement is relatively new. Modular internal distractor (MID) offers the advantage of patient compliance and minimal discomfort. The purpose of this study was to evaluate the versatility of intraoral distractors in midface advancement...

BACKGROUND: Most of cleft lip and palate patients have the esthetic and functional problems of midfacial deficiencies due to innate developmental tendency and scar tissues from repeated operations. In these cases, maxillary protraction is required for the harmonious facial esthetics and functional occlusion. CASE PRESENTATION: A 7-year old boy had been diagnosed as severe maxillary constriction due to unilateral complete cleft lip and palate. The author tried to correct the secondary deformity by early distraction osteogenesis with the aim of avoiding marked psychological impact from peers of elementary school...

INTRODUCTION: Management of adult patients with a cleft lip and palate is often multidisciplinary. The aim of orthodontic treatment is to correct the malocclusion. When the skeletal dysmorphosis is significant, the solution has to be orthognathic surgery. OBSERVATION: The authors report the case of a 16-year-old patient with a cleft lip and palate and a skeletal Class III. The aim of the orthodontic treatment was to correct dento-alveolar compensations. The skeletal discrepancy was corrected by maxillary advancement and mandibular setback...

BACKGROUND: Although conventional two-dimensional (2D) methods for orthognathic surgery planning are still popular, the use of three-dimensional (3D) simulation is steadily increasing. In facial asymmetry cases such as in cleft lip/palate patients, the additional information can dramatically improve planning accuracy and outcome. The purpose of this study is to investigate which parameters are changed most frequently in transferring a traditional 2D plan to 3D simulation, and what planning parameters can be better adjusted by this method...

BACKGROUND: Hemifacial microsomia (HFM) is the second most common congenital craniofacial deformity after cleft lip and palate. Distraction osteogenesis (DO) is regarded as an alternative and efficient treatment option for patients with HFM. However, DO was not proven effective for all cases, and the results of long-term follow-up were not satisfactory as expected. Compared with DO, the orthognathic surgery approach may offer more stable clinical outcomes for this kind of disease. The purpose of this study is to evaluate the long-term clinical and radiographic outcome of bimaxillary orthognathic surgery in the treatment of adult HFM...

This article aimed to present a case of 22 year-old Thai female with cleft lip and palate who had malocclusion developed from dental problems, skeletal disharmony and unrepaired alveolar cleft. The treatment was orthodontic combined with one-stage surgical correction which corrected skeletal discrepancy and alveolar cleft in single operation. After treatment, the patient had improved in facial esthetics, attaining good occlusal function and continuous maxillary dental arch. This procedure can reduce morbidity, preclude a second hospitalization and the cost of two-stage surgical correction...
