Summary
Deep neck infections (DNIs) are challenging due to complex anatomy. Computed tomography (CT)-guided navigation successfully aided in abscess drainage for a patient with DNIs, preventing recurrence.
Area of Science:
- Otorhinolaryngology
- Head and Neck Surgery
- Medical Imaging
Background:
- Deep neck infections (DNIs) present significant treatment challenges due to the complex anatomy of the cervical region.
- Inflammation-induced anatomical changes in DNIs often impede accurate abscess localization, leading to failed surgical drainage attempts.
Observation:
- A 76-year-old female patient presented with trismus and facial swelling following a lower third molar extraction.
- Computed tomography (CT) identified a 2.5 cm abscess with cellulitis in the right pterygomandibular space.
Findings:
- An initial intraoral surgical drainage and antibiotic therapy were ineffective.
- A subsequent CT-guided navigation system facilitated successful pus evacuation, leading to significant clinical improvement.
Implications:
- CT-guided navigation is a valuable tool for surgical drainage in complex DNIs, particularly when abscess localization is difficult.
- This technique can improve patient outcomes and reduce infection recurrence in deep neck space infections.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

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...

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...

01:19Veins of Head and Neck
5.5K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

01:20Cavity Drainage and Flashings in Masonry walls
449
Typically, a cavity wall consists of two wythes separated by a gap of at least 2 inches, which may contain insulation while still maintaining a minimum clear space of 1 inch to facilitate adequate drainage. Advanced methods like the insertion of a continuous drainage mat can further reduce this space while ensuring effective moisture expulsion.
Weep holes, strategically placed at the base of the cavity, are critical for draining accumulated water. These openings are created by leaving head...
