Eyelid tumors anmd renal transplantation.

The high incidence of malignant neoplasms in renal transplant recipients and other immunosuppressed patients is well recognized. A large proportion of these neoplasms are skin cancers. The frequent occurrence of other ocular complications, such as cataract, elevated intraocular pressure, hypertensive retinopathy, cytomegalovirus retinitis, and herpetic keratitis in patients after kidney transplant, has also been described. This report presents the clinical and histopathologic features of eyelid involvement by keratoacanthoma and squamous cell carcinoma in two patients after renal transplantation and alerts ophthalmologists to the potential for this association.

Eyelid reconstruction by the semicircle flap technique.

The semicircle flap technique of eyelid reconstruction is a modified lateral advancement-rotation flap. The procedure combines the use of selective lysis of the limbs of the lateral canthal tendon with a semicircular skin-muscle flap confined to the region of the lateral canthus within the boundary established by the lateral eyebrow and the arc it defines. Reconstruction of one half to more than three fourths of the lower or upper eyelid can be accomplished without borrowing tissue from the eyelids, nose, ear, or mouth. Large forehead, brow, or cheek flaps are elininated, as is the need for closure of the palpebral fissure during the early healing course. The procedure has been used in the reconstruction of 36 lower eyelids and five upper eyelids in 40 patients, with a follow-up period of six months to six years. The usual indication for the use of this procedure is reconstruction of a central, marginal lid defect following the excision of a neoplasm. However, it may also be useful in cases of tissue loss caused by trauma, or for severe lid malpositions for which major kid reconstruction is necessary. The early and long-term cosmetic and functional results have been gratifying.

Correction of brow ptosis.

Brow ptosis should be corrected prior to a blepharoplasty. The superotemporal approach can be used, but the supraciliary incision is the preferred technique.

Silicone in ophthalmic plastic and reconstructive surgery: a review and laboratory trial.

Silicone is a material with wide application as an exogenous implant in ophthalmic surgery. Animal trials have indicated that extreme care must be taken in the use of this material in the presence of a viable eye. Acute corneal injury was seen in 10 of 14 rabbit eyes tested with a topical application of RTV silicone in the conjunctival cul-de-sac. Two of the 10 eyes demonstrated delayed healing of the corneal injury. Pretreatment with a viscous ocular lubricant, limited corneal contact time of the hardened forms, thorough and frequent corneal evaluation and prompt appropriate treatment of abnormalities are recommended for the successful use of silicone as an orbital molding material in the presence of the viable globe. For use as an orbital expander or as a stent after soft tissue socket reconstruction, despite its relative softness compared to acrylic orbital conformer, similar precautions must be observed to prevent mechanical corneal injuries.

Surgical treatment of complications of cosmetic blepharoplasty.

The principles of repair of complications of cosmetic blepharoplasty are aimed at correction of the deformity present. Shortage of skin is usually corrected by skin grafting, lax lower lids by lid shortening procedures, and poor upper lid closure by releasing restricting tissues. Some unusual complications and their treatment are also described.

Surgical treatment of eyelid neurofibromas.

The classical surgical treatment of eyelid neurofibromas has been careful dissection of the tumor with preservation of much of the surrounding abnormal lid tissues. The reported outcome has been uniformly unfavorable. These tumors infiltrate extensively and are impossible to dissect out completely. However, the lateral location of lid neurofibromas allows "en bloc" resection of most of the tumor including the adjacent involved lid tissues. Levator function in these cases is potentially good and the lid will elevate well if the levator aponeurosis is joined to the tarsus laterally at the time of surgery. The four cases presented here indicate that this procedure is technically easier and may produce more acceptable results than other forms of treatment.

Sebaceous adenocarcinoma of the eyelid. Definition of surgical margins.

Carcinoma of the sebaceous glands of the eyelid carries a serious prognosis. Although uncommon, the diagnosis must be frequently considered owing to the similarity of the early signs of adenocarcinoma to those of chalazion. Three cases with proved sebaceous adenocarcinoma of the eyelid are reviewed to relate subtle evidence of clinical and histopathological malignancy to surgical management.

The use of the "lateral canthal sling" in ectropion repair.

We describe the use of the "lateral canthal sling" in the treatment of non-cicatrical "senile" ectropion of the lower lid. Combined with a resection of the lower retractors and the hypertrophied palpebral conjunctiva we consider it the treatment of choice for repairing non-cicatrical "marginal" ectropion. We offer a theory of the pathogenesis of the latter.

Acute dacryocystic retention.

Acute dacryocystic retention is a disease of adults under 50 years old due to a noninfective foreign body blocking the nasolacrimal duct. It is characterized by the sudden onset of severe unilateral facial pain without significant localized swelling or erythema. Palpation of the involved lacrimal sac reveals slight induration and marked tenderness. Percutaneous aspiration of lacrimal sac contents, followed by probing of the nasolacrimal duct, is usually curative.

Granular cell myoblastoma of the lid: case report.

Granular cell myoblastoma, a tumor found commonly in the tongue and subcutaneous tissue, has rarely been reported in the orbital region. The second case of primary granular cell myoblastoma in the eyelid is reported.

Technique of combined lid and medial canthus reconstruction.

Standard lid reconstruction techniques (sliding flaps or tarsoconjunctival grafts) may be combined with the Laissez-Faire treatment of large medial canthal defects. Using this methods, satisfactory results were achieved in three cases in which it was necessary to excise both a large portion of an eyelid and the adjacent medial canthus.

Reconstruction of the central one half of an eyelid.

The technique recommended in this communication concerns the use of a semicircular graft from the lateral canthal area to close a lid margin defect comprising one half of the lid. When the defect is closed, the semicircular flap will straighten and become the lateral portion of the lid.
