Purpose: To compare 2 different approaches for 3-wall orbital decompression in patients with disfiguring proptosis due to Graves' orbitopathy, and to determine which technique is preferable.
Design: Retrospective nonrandomized study with a concurrent comparison group.
Participants: Charts of 74 consecutive patients with disfiguring proptosis due to Graves' orbitopathy who underwent coronal (46) or swinging eyelid (28) decompression between January 1, 2000 and January 1, 2004 were studied retrospectively. Patients with dysthyroid optic neuropathy were excluded.
Methods: We analyzed the following parameters: proptosis reduction, ocular motility, number of additional operations, number and kind of complications, patients' satisfaction, patients' estimation of numbness or abnormal sensations in the field of operation and surgical scars, and duration of hospitalization time.
Main Outcome Measures: Reduction of proptosis, changes in eye motility, and duration of hospitalization.
Results: Mean proptosis reductions were 4.8 mm (range, 1-11) after coronal decompression and 5.6 mm (range, 0-8) after swinging eyelid decompression (P = 0.025). Patients who were operated by the swinging eyelid approach had no more deteriorated motility and a shorter hospitalization time. Complications were seen rarely. Both groups of patients showed high satisfaction scores.
Conclusion: Relative to the coronal approach, swinging eyelid decompression results in at least the same proptosis reduction, no greater motility disturbance, and a shorter hospitalization time.

Primary simple conjunctival cysts are congenital, non-neoplastic, fluid-filled lesions lined by non-keratinizing squamous epithelium without dermal appendages. They are usually located in the anterior superonasal or superotemporal orbit and are typically managed with complete surgical excision. A 69-year-old woman presented with a 10-month history of diplopia and a 2-week history of right lower eyelid swelling.

Purpose: To describe an upper eyelid swinging approach (U-Swing) that is suitable for the surgical excision of a large benign encapsulated lesions located in the intraconal space superolateral to the optic nerve.
Methods: This is a retrospective case series. The study included a review of five patients' records who had large encapsulated intraconal masses, superolateral to the optic nerve, and who underwent surgical excision with the U-Swing approach in the authors' institute over the last 10 years.

Article Synopsis
- A new method for removing masses in the orbital lobe of the lacrimal gland was tested using a transconjunctival technique with a swinging upper eyelid flap.
- In a study of three patients, this technique involved a conjunctival incision and did not leave visible scars, successfully removing the masses without complications.
- The approach provides good visibility for safely excising large masses, avoids the need to remove bone, and maintains cosmetic appearance.

Objective: To describe release of the inferior orbital fissure (IOF) as a novel surgical technique that will improve access to the inferior and inferolateral orbital apex.
Design: Laboratory investigation.
Participants: Human cadaver heads.
Article Synopsis
- The authors present the reverse lid swinging approach, which includes specific surgical techniques to access the orbit, enabling effective removal of tumors or drainage of abscesses.
- In a case series of four patients, this method was successfully used without any complications, such as optic nerve issues or eye movement problems.
- All surgeries resulted in good cosmetic outcomes, with no visible scars, highlighting the technique's effectiveness for medial orbital lesions.
