Outcomes after surgical excision of large and massive orbital tumors.

Purpose: To evaluate the outcome of surgical excision of large and massive orbital tumors. To the best of our knowledge, this is the first article to evaluate the relationship between the size of orbital tumors and the surgical outcome.

Methods: We retrospectively reviewed the charts of 34 consecutive patients affected by large or massive orbital tumors that underwent orbitotomy with en-bloc excision of the lesion.

The microbiologic spectrum of dacryocystitis: a national study of acute versus chronic infection.

Purpose: To examine the microbiologic spectrum of dacryocystitis, specifically characterizing differences between acute and chronic infection.

Methods: National multicenter prospective study of the microbiologic spectrum of acute and chronic dacryocystitis based on culture results reported between March 2005 and March 2006. Chi-square analysis was used to compare differences between groups.

Transcaruncular medial canthal ligament plication for repair of lower eyelid malposition.

Objective: To evaluate the long-term efficacy of transcaruncular medial canthal ligament (MCL) plication in the treatment of eyelid malposition.

Methods: Transcaruncular MCL plication was performed on 176 eyelids of 125 patients with symptomatic ocular exposure due to lower eyelid malposition in which MCL laxity was an important component. Preoperative and postoperative ocular exposure symptoms, lower eyelid position, lagophthalmos, and keratopathy were compared.

Comprehensive midfacial elevation for ocular complications of facial nerve palsy.

Background: A chief morbidity of facial nerve palsy is ocular exposure, which is largely due to lower lid retraction and ectropion.

Objective: To assess the role of midfacial elevation in the comprehensive surgical treatment of paralytic lower lid malposition and ocular exposure.

Methods: Eleven patients with chronic facial nerve palsy causing symptomatic ocular exposure were treated with subperiosteal midface elevation as a component of comprehensive lower lid elevation.

Lacrimal gland hemangiopericytoma.

A 45-year-old man and a 21-year old man presented with palpable lacrimal gland fossa masses and mechanical ptosis and proptosis, respectively. Computed tomography demonstrated well-circumscribed, partially cystic tumors. Echography in one case showed a well-outlined, predominantly low-reflective lesion with cysts and moderate vascularity detected by Doppler flow and standardized A-scan studies.
