Bone Disorders

Bone 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...

Summary

Facial fracture patterns change with age. Younger individuals are more prone to nasal fractures, while older individuals experience more zygomaticomaxillary complex fractures due to age-related skeletal changes.

Background:

Facial structures and fracture patterns evolve with age.
The specific link between midfacial skeletal aging and fracture distribution is not well-understood.

Purpose of the Study:

To investigate the relationship between patient age and the distribution of facial fractures.
To explore age-related changes in midfacial skeletal anatomy and their correlation with fracture patterns.

Main Methods:

Retrospective analysis of clinical records and computed tomography (CT) scans from 186 patients with facial trauma (ages 1-90).
Fracture patterns were categorized, and statistical analysis was performed to identify age associations.
Three-dimensional CT reconstructions were used to measure midfacial skeletal parameters in patients without fractures.

Main Results:

Nasal fractures were significantly associated with younger age (P = 0.023).
Zygomaticomaxillary complex fractures showed a significant association with older age (P = 0.039).
In patients without fractures, increased bony orbital volume and sagittal prominence positively correlated with age (P < 0.01).

Conclusions:

Age influences the likelihood of specific facial fracture types.
Age-related increases in orbital volume and midfacial prominence may predispose older individuals to zygomaticomaxillary complex fractures.
