Anatomy of the orbital septum and associated eyelid connective tissues. Implications for ptosis surgery.

The anatomy of the orbital septum and associated eyelid connective tissues was examined using cadaver dissection, histologic sections, surgical observations, and special radiologic imaging. The embryologic development of the eyelid connective tissues was also reviewed. Examination revealed a distinct layer of fibroadipose tissue in the eyelid and eyebrow posterior to the orbicularis and frontalis muscles, and anterior to the orbital septum. Fibrous septa within the submuscular fibroadipose tissue become contiguous with more compact lamellae of the orbital septum posteriorly imparting a multilayered quality to the orbital septum. Fat within the fibroadipose layer anterior to the orbital septum may be mistaken for the preaponeurotic fat pad by the unwary surgeon and may lead to surgical error. The orbital septum and the levator aponeurosis were found to join 2 to 5 mm above the superior tarsal border (average, 3.4 mm). Recommendations for ptosis surgery based on these anatomic principles are given.

Transconjunctival frontalis suspension (TCFS).

We have devised a frontalis suspension technique originally described in an article entitled, "Transconjunctival frontalis suspension for blepharoptosis" (Trans Am Acad Ophthal Otolaryngol 83:684-92), by Swan and Tongue in 1977. This modified transconjunctival frontalis suspension (TCFS) procedure is described. It has been used at the Oregon Health Sciences University in its original or modified form since 1970. To better understand how this procedure successfully corrects blepharoptosis in patients with poor levator function, a study was undertaken to discern the anatomic relationship of the suspension material to important ocular adnexal structures. The findings are based on gross anatomic dissection and histologic examination of a cadaver eyelid after postmortem transconjunctival fascia lata frontalis suspension. The distal, horizontal limb of the fascia suspends the central portion of the levator aponeurosis in a hammock-type fashion. The two vertical limbs pierce the aponeurosis at the level of Whitnall's ligament and incorporate this ligament. The fascia then exits the orbit through the orbital septum near the arcus marginalis and is incorporated into the frontalis muscle near the junction of the medial one-third and lateral two-thirds of the brow, temporal to the supraorbital neurovascular bundle. This anatomic location is not only relatively easily and safely attained, but also maximizes the principles of more traditional frontalis suspensions while minimizing the effort and surgical manipulation.

Blepharoptosis↗

Surgical technique for ptosis repair.

There are many choices of operation for ptosis repair, but proper classification, diagnosis and an understanding of eyelid anatomy are essential. The anterior levator resection is recommended for ptosis repair with levator function, and fascia lata suspension is described for ptosis repair when no levator function is present.

Blepharoptosis↗

Lacrimal probing complications.

Probing can be accomplished at any age with extreme care. Whenever an individual believes he has developed a false passage, he should stop and come back at a later date to accomplish opening of the obstructed nasolacrimal duct.

The cure of ptosis by aponeurotic repair.

Indications for the procedure of aponeurotic repair are nearly all of the ptoses that have 8 mm or more of elevation from downward to upward gaze. Such cases have a levator with an adequate striated part, an inadequate superior tarsal (Müller) muscle, and an aponeurosis that has involutional changes such as a dehiscence or disinsertion. Local anesthesia is advised. The incision is made 7 mm above the lash-line, through the skin and pretarsal muscle only. Blunt dissection upward is used until the preaponeurotic fat pad is uncovered. The upper part of the aponeurosis is picked up under the fat pad and sutured to the lower part of the aponeurosis with 5-0 chromic gut. Fifty-seven eyelids in thirty-four patients have been operated on, with excellent results and minimal trauma.
