#zygomatic arch

[vulturegroove]

The suture between the maxilla and zygomatic (jugal) is pretty different on each side. Any ideas why?

It is one-thirty-two am on the twenty-first of February twenty-twenty-two and I just learned what a zygomatic arch is

This is a 33-year-old male patient from Siliguri. He met with an accident about three months ago. He underwent emergent treatment at a nearby local hospital. He realized that the accident had left him with a left sided double vision. He underwent three surgeries for his double vision, but this persisted. A depressed fracture of his left eyebrow and maxilla had left him with facial asymmetry.

None of these issues were set right by the three surgeries. The oral surgeon who operated on him referred him to our hospital. He told the patient that all his problems would be set right.

He presented for consultation. Dr SM Balaji examined him and recommended a 3D CT scan. This revealed a malunited zygomaticomaxillary complex fracture. The treatment plan was then explained to the patient. This would involve the use of a costochondral bone graft.

A costochondral bone graft was first harvested from the sixth intercostal rib. Reconstruction of the lateral wall of orbit and orbital floor was then done with a Titan Medpor mesh. This corrected the diplopia and enophthalmos. The left zygomatic arch was then refractured and pushed inwards. Attention then turned to the left maxillary defect and depression in the left eyebrow.

This was by using a costochondral bone graft, which was then fixed using titanium screws. The deviated left nasal bridge was then corrected using lateral osteotomy. The patient was very satisfied with the results of the surgery.
