The lacrimal keyhole, orbital door jamb, and basin of the inferior orbital fissure. Three areas of deep bone in the lateral orbit.

Objectives: To calculate the volume of bone in 3 areas of the deep lateral orbit that are available for removal in decompression surgery and to demonstrate these 3 areas within a 3-dimensional computed tomographic reconstruction of the orbit.

Design: The 3 areas of bone in the deep lateral orbit were designated the lacrimal keyhole, the sphenoid door jamb, and the basin of the inferior orbital fissure. By means of digitized computed tomographic scans, these 3 areas of bone were analyzed by measuring preoperative and postoperative orbital volumes and predicted bony expansion volumes in 9 patients (17 orbits) who underwent deep lateral orbital decompression surgery.

Blepharoplasty and periorbital surgery.

Blepharoplasty is one of the most successful aesthetic surgical procedures. Careful preoperative planning and conservative tissue resections can help to minimize complications and optimize results. Although some young patients request blepharoplasty specifically because of age-related changes in the eyelid skin, the surgery is that of sculpture and contouring of the entire aesthetic unit.
