Sutures of the Skull

Sutures of the Skull

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...

Tooth Anatomy

Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

Cranial Bones: Superior and Posterior View

Cranial Bones: Superior and Posterior View

The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Cranial Bones: Lateral View

Cranial Bones: Lateral View

The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Development of the Limb Synovial Joints

Development of the Limb Synovial Joints

Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...

Summary

This study analyzed surgical approaches to the temporomandibular joint (TMJ) in adult cadavers and patients. A novel intrauriculo-temporalis approach was validated, with guidelines developed for selecting TMJ surgical access methods.

Area of Science:

Anatomy
Surgical Techniques
Temporomandibular Joint Disorders

Background:

The temporomandibular joint (TMJ) is complex, requiring precise surgical access for effective treatment.
Existing surgical approaches to the TMJ have limitations that necessitate further investigation.
Understanding anatomical variations is crucial for optimizing surgical outcomes in TMJ procedures.

Purpose of the Study:

To evaluate criteria for operational wounds in various surgical accesses to the temporomandibular joint.
To substantiate a new intrauriculo-temporalis surgical approach for the TMJ.
To develop evidence-based indications for choosing surgical access in TMJ diseases and injuries.

Main Methods:

Anatomical study on 30 adult human cadavers examining wound criteria for preauricularis, intrauricularis, intrauriculo-temporalis, and posterior mandibullaris accesses.
Retrospective analysis of 289 surgical operations performed on 268 patients with various TMJ conditions.
Correlation of surgical access choice with specific TMJ pathologies and injuries.

Main Results:

Detailed criteria for operational wounds were established for each studied TMJ surgical access.
The novel intrauriculo-temporalis surgical access was demonstrated as a viable and effective approach.
A comprehensive set of indications for selecting the most appropriate surgical access for diverse TMJ pathologies was formulated.

Conclusions:

The study provides a robust foundation for understanding and selecting surgical approaches to the TMJ.
The newly validated intrauriculo-temporalis access offers a promising alternative for specific TMJ surgical interventions.
Clinical guidelines derived from this research will aid surgeons in optimizing TMJ treatment strategies.
