Summary
Midfacial distraction osteogenesis using Le Fort II surgery successfully treated a 2-year-old boy with Down syndrome and respiratory issues. Careful consideration is needed due to potential respiratory muscle weakness in these patients.
Area of Science:
- Craniofacial Surgery
- Pediatric Plastic Surgery
- Genetics and Rare Diseases
Background:
- Patients with Down syndrome often exhibit craniofacial anomalies like midfacial hypoplasia, which can contribute to respiratory problems such as obstructive sleep apnea.
- Specific features include epicanthal folds, up-slanting palpebral fissures, flat nasal bridge, and relative macroglossia, which may be candidates for surgical intervention.
- Midfacial hypoplasia in Down syndrome has been linked to respiratory disorders, yet surgical interventions like distraction osteogenesis have not been widely reported for this specific indication.
Purpose of the Study:
- To report the successful surgical intervention for midfacial hypoplasia causing respiratory issues in a pediatric patient with Down syndrome.
- To document the use of Le Fort II distraction osteogenesis with a halo-type external device in this specific patient population.
- To highlight the potential benefits and necessary precautions for this procedure in children with Down syndrome.
Main Methods:
- A 2-year-old boy with Down syndrome presenting with respiratory compromise due to midfacial hypoplasia underwent Le Fort II distraction osteogenesis.
- A halo-type external distraction device was utilized to facilitate the midfacial advancement.
- Surgical outcomes and patient recovery were monitored post-operatively.
Main Results:
- The Le Fort II distraction osteogenesis procedure was successfully performed, leading to positive outcomes in the patient.
- The surgical intervention effectively addressed the midfacial hypoplasia contributing to the respiratory disorder.
- The use of a halo-type external distraction device proved effective in this case.
Conclusions:
- Le Fort II distraction osteogenesis is a viable surgical option for correcting midfacial hypoplasia and associated respiratory disorders in select patients with Down syndrome.
- Despite successful outcomes, the inherent respiratory muscle weakness in patients with Down syndrome necessitates careful patient selection and cautious surgical planning.
- Further research and case studies are warranted to establish definitive guidelines for this procedure in the Down syndrome population.

01:27Compact Bone
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:31Bone Remodeling and Repair
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
