CPT® Code 21387

The CPT® Code 21387 refers to the open treatment of an orbital floor blowout fracture using a combined approach. This procedure is specifically designed to address the anatomical and functional defects that arise from an orbital floor fracture, which is a common consequence of mid-facial trauma. Such fractures can lead to complications such as extraocular muscle entrapment, resulting in impaired eye movement, as well as aesthetic deformities of the face. The combined approach involves both transconjunctival and lateral canthotomy techniques, allowing for effective access to the orbital area. During the procedure, traction sutures are strategically placed in the lower eyelid to facilitate the surgical approach. An incision is made along the palpebral fissure, which involves cutting through the skin, orbicularis oculi muscle, and conjunctiva. The procedure continues with the transection of the lateral canthal tendon fibers, enabling the lower eyelid to be everted for better visibility and access to the orbital floor. The surgical steps include careful dissection, removal or repositioning of herniated orbital tissue, and meticulous closure of the incisions to restore both function and appearance. This comprehensive approach ensures that the underlying issues associated with the fracture are effectively addressed, promoting optimal recovery and restoration of normal eye function.
