Summary
Ossification of the stylohyoid ligament (SHL) primarily develops during childhood and adolescence. The length of ossified SHL sites increases linearly until late adolescence, then slows significantly.
Area of Science:
- Orthodontics and Dental Development
- Skeletal Biology
- Radiographic Anatomy
Background:
- The stylohyoid ligament (SHL) can undergo ossification, a process with potential clinical implications.
- Understanding the developmental trajectory of SHL ossification is crucial for interpreting radiographic findings.
Purpose of the Study:
- To investigate the longitudinal development of stylohyoid ligament ossification.
- To correlate ossification patterns with patient age and malocclusion treatment.
Main Methods:
- Longitudinal radiographic study design.
- Analysis of ossified sites within the stylohyoid ligament.
- Measurement of ossified site length and location.
- Correlation with patient age and developmental stages.
Main Results:
- The majority of stylohyoid ligament ossification occurs during childhood and adolescence.
- Mean ossified site length increases linearly with age until the end of adolescence.
- Ossified sites shift from superior to other ligament parts with increasing age.
- Inferior SHL ossification near the hyoid bone is more common than previously documented.
Conclusions:
- Stylohyoid ligament ossification is a developmental process largely established by adolescence.
- Age-related changes in ossification patterns and length are evident.
- Findings contribute to a better understanding of SHL ossification prevalence and distribution.

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...

01:22Sutures 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...

01:12The Hyoid Bone
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...
01:19Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
01:09Changes in the Appendicular Skeleton with Age
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...

01:26Muscles of the Anterior Neck
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...
