Large anterior orbital cyst as a late complication of chalazion surgical drainage.

PURPOSE: To present four patients who developed large cystic lesions attached to the tarsal plate at the site of previously drained chalazion. METHODS: Medical records for all patients who developed cystic lesion as a complication of chalazion surgery were retrospectively reviewed for clinical and radiological findings, treatment provided, histopathological findings, and complications. RESULTS: Four patients (one male and three females) with a mean age of 22 years (range, 11-36 years) were enrolled in the study. A history of chalazion surgery was present in all patients at the same site of the cyst attachment to the tarsal plate. The mean interval between the presentation with the cystic lesion and the chalazion surgery was 13 weeks (range, 6-24 weeks). All patients were treated with surgical excision of the cysts, along with local triamcinolone injection. Histopathological findings of the excised cysts were consistent with chalazion. There was no evidence of recurrence or other complication observed during the follow-up visits (the minimum follow-up duration was 6 months). CONCLUSIONS: Anterior orbital cystic formation (prolapsed chalazion) may occur as a late complication of chalazion surgery. Surgical excision along with steroid injection was effective to manage this rare complication among our patients.

Entropion in children with isolated peripheral facial nerve paresis.

PURPOSE: Adults with facial nerve paresis (FNP) generally develop ectropion, but a recent report of children with syndromatic FNPs implies that entropion may be more common in this setting than ectropion. This study evaluates eyelid position and other periorbital changes in children with isolated, non-syndromatic FNP. METHODS: Charts were reviewed of 10 sequential children who presented to a major national eye referral centre with isolated FNP of variable aetiology. Severity of FNP was assessed according to the House-Brackmann scale. RESULTS: All 10 patients (4 males and 6 females; mean age at presentation, 4 years) had unilateral, isolated FNP. Mild lower-eyelid entropion was present in four patients, and severe lower-eyelid entropion required surgical correction in three patients. All patients had lower eyelid retraction (mean 2.3 mm) and lagophthalmos (mean 2.9 mm). None had enophthalmos, lower eyelid ectropion, or brow ptosis. CONCLUSION: Unlike adults, children with isolated FNP seem prone to develop entropion rather than ectropion. Entropion reported previously in five syndromic children with FNP seems more likely related to patients' age than to their congenital syndromes.
