What is the CPT code for excision of styloid process?
Another potential option is M89. 8X8 (Other specific disorders of Bone, unspecified site). When coding for shortening of the styloid process use CPT code 21499 Unlisted musculoskeletal procedure, head.
Where is styloid process?
Styloid process is derived from the Greek word stylos, meaning a pillar. The structure is a long, cylindrical, cartilaginous bone located on the inferior aspect of temporal bone, posterior to the mastoid apex, anteromedial to the stylomastoid foramen, and lateral to the jugular foramen and carotid canal.
What is elongated styloid process?
The styloid process of the temporal bone is an elongated, conical projection that lies anterior to the mastoid process. In the neck, it is situated between the internal and external carotid arteries and is lateral to the tonsillar fossa.
Why is styloid process removed?
Surgery to shorten the styloid process is the primary treatment for Eagle syndrome. This procedure, called a styloidectomy, can be done through the mouth or neck. Surgery through the mouth requires removal of the tonsils , and it can be more difficult for the surgeon to access the styloid process.
What is Eagle syndrome?
Eagle syndrome is characterized by recurrent pain in the middle part of the throat (oropharynx) and face. “Classic Eagle syndrome” is typically seen in patients after throat trauma or tonsillectomy. Symptoms include dull and persistent throat pain that may radiate to the ear and worsen with rotation of the head.
What is a styloid process?
: any of several long slender pointed bony processes: as. a : a sharp spine that projects downward and forward from the inferior surface of the temporal bone just in front of the stylomastoid foramen and that is derived from cartilage of the second visceral arch.
What is the styloid process made up of?
The styloid process is a cylindrical, slender, needle-like projection of varying lengths averaging 2 to 3 cm. The styloid process projects from the inferior part of the petrous temporal bone and offers attachment to the stylohyoid ligament and the stylohyoid, stylopharyngeus, and styloglossus muscles.
What is styloid process of radius?
The radial styloid process is found on the lateral surface of the distal radius bone. It extends obliquely downward into a strong, conical projection. The tendon of the brachioradialis attaches at its base. The radial collateral ligament of the wrist attaches at its apex.
What is a radial Styloidectomy?
Radial styloidectomy is an early salvage procedure that may provide short term relief of mechanical pain from radial styloid impingement. This is a form of wrist osteoarthritis that can arise due to a longstanding scaphoid nonunion or due to a chronic scapholunate ligament tear (link to styloidectomy 1).
Where is ulnar styloid process?
The ulnar styloid is located at nearly the ulnar-most (the opposite side of the humerus with the elbow flexed) and slightly dorsal aspects of the ulnar head on the axial plane. It should appear almost midway (55% dorsally) from the ulnar head on the standard lateral view of the wrist in neutral forearm rotation.
What is mastoid and styloid process?
The mastoid process is located posterior and inferior to the ear canal, lateral to the styloid process, and appears as a conical or pyramidal projection. It forms a bony prominence behind and below the ear. It has variable size and form (e.g. it is larger in the male than in the female).
What articulates with the styloid process?
end of the radius, the styloid process, may be felt on the outside of the wrist where it joins the hand. The inside surface of this process presents the U-shaped ulnar notch in which the ulna articulates.
