Reconstruction of Large Full-Thickness Lower Eyelid Defects With Remnant Eyelid Rotation, Semicircular Skin and Muscle Flap, and Lateral Tarsoconjunctival Flap.

PURPOSE: To describe and assess the results of reconstruction of large, full-thickness defects of the central or medial lower eyelid using a semicircular skin flap, rotation of the remnant lateral eyelid, and a lateral tarsoconjunctival flap. METHODS: The surgical approach is described, and the authors performed a retrospective chart review of consecutive patients between 2017 and 2023 reconstructed with this technique. Outcomes were assessed for size of eyelid defect, vision, subjective symptoms, facial and palpebral aperture symmetry, eyelid position and closure, corneal examination, surgical complications, and need for subsequent surgical intervention. Postoperative appearance was graded on malposition, distortion, asymmetry, contour deformity, and scarring (MDACS). RESULTS: Charts of 45 patients were identified. The average size of the lower eyelid defect was 18 mm (ranging from 12 to 26 mm). Facial and palpebral aperture symmetry were acceptable and all patients had preserved visual acuity and eyelid position and closure. The MDACS cosmetic score was perfect (0) in 15.6% (7/45) of eyelids, good (1-4) in 80.0% (36/45) of eyelids, and mediocre (5-14) in 4.4% (2/45) of eyelids. Second stage reconstruction was not necessary in 32 (71.1%) cases. There were no serious surgical complications, but minor complications included redness of the eyelid margin and pyogenic granulomas. CONCLUSIONS: Medial rotation of the remnant lower eyelid with a lateral semicircular skin and muscle flap over a lateral tarsoconjunctival flap was very effective in this series. Benefits include scarring within the facial skin tension lines, maintained vision throughout the recovery period, no eyelid retraction, and often single stage reconstruction.

Bilateral Dacryoadenitis and Central Nervous System Involvement in a Child With Kimura Disease.

Kimura's disease (KD) is a systemic inflammatory condition characterized by lymphadenopathy and subcutaneous nodules in the head and neck region. The lesions have a distinctive histopathological pattern formed by follicular hyperplasia, eosinophilic infiltrates, fibrosis, and vessel proliferation. The disease may occur at all ages but predominates among young males with autoimmune dysfunctions. Visceral and orbital involvement is uncommon. We report a girl with KD who developed bilateral enlargement of the lacrimal glands and a lesion in the left lateral ventricle of the brain indistinguishable from a central nervous system neoplasia. A biopsy of both the lacrimal gland and the lateral ventricle was consistent with KD.
