Summary
Temporomandibular joint (TMJ) ankylosis reconstruction using costochondral grafts can achieve excellent functional and aesthetic outcomes. Early diagnosis and treatment are crucial for successful management in maxillo-facial surgery.
Area of Science:
- Maxillofacial Surgery
- Orthodontics
- Regenerative Medicine
Background:
- Temporomandibular joint (TMJ) ankylosis presents a significant surgical challenge, particularly in pediatric cases requiring restoration of form and symmetrical growth.
- Bilateral bony TMJ ankylosis can lead to severe facial deformities, such as the characteristic 'bird face' appearance.
Observation:
- A female patient with severe facial deformity due to bilateral TMJ ankylosis was treated with condylectomy and costochondral grafting.
- Initial treatment anticipated the need for subsequent orthognathic surgery or bone grafting.
Findings:
- The costochondral graft facilitated TMJ reconstruction, promoting functional recovery and aesthetic improvement.
- Remarkably, the graft's growth and release of ankylosis obviated the need for further surgical interventions.
Implications:
- This case highlights the potential of costochondral grafting in achieving successful TMJ reconstruction without secondary procedures.
- Emphasizes the importance of early clinical recognition of TMJ ankylosis signs and symptoms for timely intervention by dentists.

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...
01:40Bone Remodeling
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.
01:24Bone Formation by Endochondral Ossification
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...
01:17Structural Joints: Cartilaginous Joints
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary or...

01:29Bone Formation by Intramembranous Ossification
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...

01:20The Thoracic Cage: Ribs
Ribs are curved, flattened bones forming the thoracic cavity wall with the thoracic muscles. There are 12 pairs of thoracic ribs. The posterior ends of all the ribs articulate with the T1–T12 thoracic vertebrae. In contrast,the anterior ends of most ribs attach to the sternum via their costal cartilages.
Parts of a Typical Rib
A typical rib has a head, neck, and body. The posterior end of the rib is called the head, followed by a narrow neck. The head articulates primarily with the costal facet...
