Summary
Mandibular lingual perimandibular vessels are close to bone, especially near the canine area. Careful implant placement is crucial to avoid severe bleeding from these floor-of-mouth blood vessels.
Area of Science:
- Anatomy
- Oral Surgery
- Vascular Anatomy
Background:
- The floor of the mouth contains critical blood vessels.
- Understanding the proximity of these vessels to the mandibular bone is vital for surgical procedures.
Purpose of the Study:
- To anatomically describe the lingual perimandibular vessels.
- To determine the distance of these vessels to the mandibular bone.
Main Methods:
- Dissection of 12 human cadaver hemifacial lower thirds.
- Exposure of floor of mouth blood vessels via sagittal incisions.
Main Results:
- Vessel diameters ranged from 0.5 to 3 mm (mean 1.5 mm).
- Smallest median vertical distance to bone was 14.5 mm in the canine area.
- Median horizontal distance to lingual plate was 2 mm at canine/molar areas.
Conclusions:
- Perforation of the lingual plate risks injury to these vessels, potentially causing hemorrhage.
- Vessels in the floor of the mouth can be near implant sites.
- Caution is advised during mandibular implant placement.

01:26Arteries of the Head and Neck
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
01:20Anatomy of Blood Vessels
The vascular system, an integral part of the circulatory system, comprises various blood vessels that play crucial roles in maintaining the body's homeostasis. These blood vessels form a complex and efficient circulatory network. The three primary categories of blood vessels are the arteries, veins, and capillaries.
Arteries
Arteries circulate oxygenated blood from the heart, except the pulmonary artery, which transports deoxygenated blood to the lungs. Large arteries, such as the aorta, have...
