Summary
Primary palatoplasty does not fully close hard palate clefts. Early surgery (before age 1) and the Von Langenbeck technique result in smaller residual clefts, suggesting improved hard palate osteogenesis.
Area of Science:
- Craniofacial surgery
- Pediatric surgery
- Oral and maxillofacial surgery
Background:
- Hard palate osteogenesis following primary palatoplasty is not well understood.
- Palatoplasty aims to close clefts, but the extent of bone regeneration in the hard palate remains a key question.
Purpose of the Study:
- To investigate the impact of primary palatoplasty on hard palate osteogenesis.
- To determine factors influencing residual hard palate cleft size and fistula formation.
Main Methods:
- Retrospective cohort study of 66 patients who underwent primary palatoplasty.
- Postoperative computed tomography (CT) imaging at least 1 year after surgery was analyzed.
- Outcomes included hard palatal cleft dimensions, fistula rates, and correlation with surgical technique and age at operation.
Main Results:
- No patients achieved complete osseous closure; an average residual cleft of 41.4% remained.
- Veau IV clefts had the largest residual defects and highest fistula rates.
- Surgery before age 1 and the Von Langenbeck technique were associated with smaller residual clefts.
Conclusions:
- Primary palatoplasty does not result in complete hard palate bone regeneration.
- Performing palatoplasty before age 1 and utilizing the Von Langenbeck technique may promote better hard palate osteogenesis.

01:40Bone Remodeling
34.4K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

01:27Growth of Cartilage and Bone Tissue
3.9K
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

01:29Bone Formation by Intramembranous Ossification
16.2K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...

01:22Sutures of the Skull
13.9K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

01:24Bone Formation by Endochondral Ossification
14.7K
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...
