What is lateral Orbitotomy?
What is lateral Orbitotomy?
The lateral orbitotomy approach was first described by Kronlein in 1888. 1. Kronlein used a curved skin incision that extended over the temporal fossa toward the ear and removed the lateral orbital wall to gain access to retrobulbar lesions.
What is Orbitotomy surgery?
During an orbitotomy, surgery is performed on the orbit that contains the eye. Various incisions are used to access the orbit. Also Known As: Orbital tumor removal. Eye surgery.
What is periorbital approach?
Periorbital rejuvenation: a safe subcutaneous approach to forehead, eyebrow, and orbicularis oculis muscle mobilization.
What is an anterior Orbitotomy?
Definition. A surgical procedure to access a specific area of the anterior orbit, generally considered to be within the anterior two-thirds of the orbit.
How do you do a lateral Canthotomy?
Use iris scissors to cut from the lateral canthus to the rim of the orbit, about 1 to 2 cm (canthotomy). Cut the inferior and sometimes both crus of the lateral canthal ligament (cantholysis). Most experts recommend starting with the inferior crus. Lift the lateral portion of lower eyelid.
What is Exenteration of the eye?
Exenteration is a surgical procedure involving removal of the entire globe and its surrounding structures including muscles, fat, nerves, and eyelids (extent determined by disease being treated).
What is Transconjunctival approach?
The transconjunctival preseptal approach is most effective surgical access to infraorbital rim and orbital floor and even to medial orbital wall. This approach is surgically similar in providing exposure and access, but aesthetically superior to other approaches and has minimal complications.
What is the lateral Canthus?
Lateral canthus: the lateral confluence of upper and lower eyelid margins. Sclera: the collagenous outer wall of the eyeball. Its outermost portion, called the episclera, has a rich vascular network. It is here that bilirubin accumulates to stain the superficial sclera yellow (“icterus”).
What is the CPT code for Orbitotomy?
67412
CPT® Code 67412 in section: Orbitotomy without bone flap (frontal or transconjunctival approach)
When is lateral Canthotomy performed?
Lateral canthotomy and cantholysis should be performed for ocular compartment syndrome (most commonly caused by retrobulbar hemorrhage) with acute loss of visual acuity, relative afferent pupillary defect, increased IOP, and proptosis.
What is lateral Canthotomy?
Lateral canthotomy, the emergency treatment for orbital compartment syndrome, is the surgical exposure of the lateral canthal tendon. Cantholysis is canthotomy plus incision of the inferior branch (crus) of the tendon.
