Summary
Bilateral coronoid hyperplasia, a rare condition, can cause limited mandibular movement. Dental professionals should consider this possibility in patients with jaw mobility issues.
Area of Science:
- Oral and Maxillofacial Surgery
- Anatomy and Physiology
Background:
- Limited mandibular movement can significantly impact a patient's quality of life.
- Coronoid hyperplasia is an uncommon condition characterized by enlargement of the coronoid process.
Observation:
- A case study detailing limited mandibular movement due to bilateral coronoid hyperplasia.
- The enlargement of the coronoid processes restricted the condyle's range of motion.
Findings:
- Bilateral coronoid hyperplasia was identified as the cause of restricted mandibular mobility.
- This condition presents a diagnostic challenge due to its rarity.
Implications:
- Highlights the importance of considering rare anatomical variations in diagnosing mandibular movement disorders.
- Informs dental surgeons about bilateral coronoid hyperplasia as a potential cause of limited jaw function.
- Emphasizes the need for thorough examination in cases of unexplained restricted mandibular movement.

01:14Muscles for Facial Expressions
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
01:22Trachea
The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of the...

01:29Tetanus
Tetanus is a life-threatening neurological disorder characterized by persistent muscle contractions and spastic paralysis. It is caused by Clostridium tetani, a motile, Gram-positive, rod-shaped, obligate anaerobe. These bacteria produce terminal endospores, giving them a distinctive “lollipop” or “tennis-racket” appearance. They thrive in anaerobic environments, such as those found in deep puncture wounds.Once introduced into the body, the spores germinate into vegetative cells. These cells...
