Long-term follow-up of a patient diagnosed with Crouzon syndrome who underwent Le Fort I and III distraction osteogenesis using a rigid external distractor system.

OBJECTIVE: This case report describes the successful treatment of a patient with Crouzon syndrome with severe midfacial deficiency and malocclusion, including reverse overjet. MATERIALS AND METHODS: In Phase I treatment, maxillary lateral expansion and protraction were performed. In Phase II treatment, after lateral expansion of the maxilla and leveling of the maxillary and mandibular dentition, an orthognathic approach including simultaneous Le Fort I and III osteotomies with distraction osteogenesis (DO) was used to improve the midfacial deficiency. RESULTS: After DO, 12.0 mm of the medial maxillary buttress and 9.0 mm of maxillary (point A) advancement were achieved, which resulted in a favorable facial profile and stable occlusion. CONCLUSION: Even after 8 years of retention, the patient's profile and occlusion were preserved without any significant relapse.

Evaluation of Facial Appearance-Related Quality of Life in Young Japanese Patients With Cleft Lip and/or Palate.

OBJECTIVE: (1) To confirm the reliability of a Japanese version of the Youth Quality of Life Instrument-Facial Differences Module (YQOL-FD); (2) to assess the quality of life (QoL) related to facial difference in Japanese youths with cleft lip and/or palate (CL/P) using this instrument; and (3) to examine the QoL differences according to age, sex, and cleft type. DESIGN: A cross-sectional study. SETTING: Japanese youths with CL/P were recruited through our hospital and asked to complete the YQOL-FD. PARTICIPANTS: Sixty-nine Japanese youths (age, 11-18 years) with CL/P. OUTCOME MEASURES: The domain scores of stigma, negative consequences, negative self-image, positive consequences, and coping in the YQOL-FD, and the reliability of such scores were evaluated. RESULTS: The instrument showed an acceptable internal consistency (Cronbach α = 0.74-0.92) and test-retest reliability (intraclass correlation coefficient = 0.94-0.98), except for the coping domain. The individual's domain scores were spread out from the lowest score to the high scores among all domains, thus indicating the negative and positive impacts of living with facial differences regarding their QoL may vary among individuals with CL/P. All domain scores in the 15- to 18-year-old group were significantly higher than those in 11- to 14-year-old group; there were no significant differences according to sex or cleft type. CONCLUSIONS: The instrument showed acceptable reliability, except for the coping domain. There were individual variations in QoL concerning the facial difference among Japanese youths with CL/P as measured by the YQOL-FD, suggesting the importance of individual evaluations. Perceptions were influenced by age, but not sex or cleft type.

Orthodontic-Surgical Approach for Treating Skeletal Class III Malocclusion With Severe Maxillary Deficiency in Isolated Cleft Palate.

Orthodontic treatment in patients with orofacial cleft such as cleft lip and palate or isolated cleft palate is challenging, especially when the patients exhibit severe maxillary growth retardation. To correct this deficiency, maxillary expansion and protraction can be performed in the first phase of orthodontic treatment. However, in some cases, the malocclusion cannot be corrected by these procedures, and thus, skeletal discrepancy remains when the patients are adolescents. These remaining problems occasionally require various orthognathic treatments according to the degree of the discrepancy. Here, we describe one case of a female with isolated cleft palate and hand malformation who exhibited severe maxillary deficiency until her adolescence and was treated with multiple orthognathic surgeries, including surgically assisted maxillary expansion (surgically assisted rapid palatal expansion), LeFort I osteotomy, and bilateral sagittal split osteotomy in order to correct severe skeletal discrepancy and malocclusion. The treatment resulted in balanced facial appearance and mutually protected occlusion with good stability. The purpose of this case report is to show the orthodontic treatment outcome of 1 patient who exhibited isolated cleft palate and subsequent severe skeletal deformities and malocclusion which was treated by an orthodontic-surgical approach.
