Orbital myopericytoma: an unusual tumor in an unusual location.

A 71-year-old male with a 4-month history of bulging, tearing, and redness in the right eye presented with vision loss, proptosis, conjunctival hyperemia, and chemosis. Magnetic resonance imaging showed a right intraconal solid mass with extraconal extension, hyper-intense in T2 sequences with heterogeneous contrast enhancement. Complete excision of the mass was performed through a lateral orbitotomy. Histological analysis revealed a neoplasm with high vessel density, solid growth of oval cells, a concentric proliferation of the wall of small vessels, and a weak and patchy positivity for smooth muscle actin. These findings were consistent with the diagnosis of myopericytoma. After surgery, visual acuity improved in the affected eye and after 18 months of follow-up there have been no signs of recurrence.

Frontalis Suspension Using Autologous Fascia Lata in Children Under 3 Years Old.

PURPOSE: To analyze functional results and complications of the use of autologous fascia lata in frontalis suspension in children under 3 years old and to confirm its technical viability. METHODS: A retrospective review of 8 patients (12 eyes) who underwent frontalis suspension using autologous fascia lata sling. RESULTS: Twelve eyes of 8 patients were analyzed, with an average age of 1.8 ± 0.6 years. Preoperatively, the mean margin-to-reflex distance 1 was -0.17 ± 0.577 mm. Postoperatively the mean margin-to-reflex distance 1 was 2.66 ± 0.492 mm without any graft donor site or corneal complications. No recurrence was recorded in the follow-up period (mean follow-up period 28.5 ± 32.33 months). CONCLUSIONS: Autologous fascia lata is an eligible material in frontalis suspension in children under 3 years old, despite the traditional oculoplastic dogma that advises against.

Reconstructive subperiosteal midface lift: A three nonvisible incision approach.

This article describes our surgical technique for subperiosteal midface elevation in patients with paralytic lower eyelid malposition or cicatricial inferior eyelid retraction. Nineteen patients with paralytic lower eyelid malposition and 15 patients with cicatricial inferior eyelid retraction underwent a subperiosteal midface lift (n = 34). The procedure was performed under local anesthesia through three nonvisible incisions. A transconjunctival incision allows preseptal dissection to the orbital rim, followed by a subperiosteal dissection of the midface. An oral incision is useful to achieve complete subperiosteal dissection and to perform the distal periostomy, which allows complete release of the midface soft tissues. A temporal incision provides access to the temporal fascia for fixation of the elevated tissues and gives the surgeon the possibility of removing redundant skin from the scalp instead of the lower eyelid. Additional posterior lamellar grafting was performed in 24 patients. There was a statistically significant reduction in the distance from the pupil centre to the lower eyelid (margin reflex distance, MRD2) 1 month after surgery (preoperative MRD2 9.62 ± 4.52 mm, postoperative MRD2 5.28 ± 2.62 mm). The ectropion and lower eyelid retraction was resolved in all patients, except for one recurrence. Midfacial elevation is a safe and effective surgical technique in the treatment of static lower eyelid malposition after chronic facial nerve palsy or posttraumatic or iatrogenic lower eyelid retraction.

Primary extraosseous Ewing sarcoma of the orbit.

A 40-year-old man presented with painless, progressive vision loss and mild proptosis of the OD. CT revealed a right intraconal mass with slight penetration of the optic canal not contiguous with any bony structure. Incisional biopsy through a transfrontal orbitotomy revealed a diffuse growth of homogeneous, small, round cells. Immunohistochemical stains were positive for vimentin and MIC2 (CD99), and the translocation at EWS gene (22q12) was detected. Metastatic workup and a full-body bone scan were negative, confirming primary orbital extraosseous Ewing sarcoma. The patient received neoadjuvant chemotherapy and an orbital exenteration with preservation of eyelids and conjunctiva. He also received adjuvant chemotherapy and local radiotherapy, and he has remained disease-free for almost 3 years.

The addition of a conjunctival flap to a posterior lamella auricular cartilage graft: A technique to avoid corneal complications.

PURPOSE: To present the benefits of the addition of a conjunctival flap when correcting lower eyelid retraction using an auricular cartilage graft. METHODS: An auricular cartilage graft was obtained either from the concha o the scaphoid fossa. When preparing the receiving bed, the conjunctival incision was made 2 mm below the inferior margin of the lower eyelid tarsus, therefore, a conjunctival flap arising from the inferior border of the tarsus was obtained. The cartilage graft was placed in the lower eyelid. The inferior border of the graft was sutured to the retractors and conjunctiva using absorbable sutures. The superior border was sutured to the inferior tarsus, so that de conjunctival flap covered the superior portion of the graft. RESULTS: Fourteen patients underwent the surgical technique. No corneal complications were observed in the early or late postoperative period. Donor site complications were not encountered. CONCLUSIONS: The confection of a conjunctival flap that lines the superior portion of an auricular cartilage graft in the lower eyelid provides protection against corneal postoperative complications until the graft is epithelized.

Congenital lacrimal sac diverticulum.

We report the case of a 6-month-old boy with recurrent episodes of acute dacryocystitis from age 3 months to 1 year of age. The cause was determined to be congenital nasolacrimal sac diverticulum, a rare and commonly asymptomatic entity. An isolated diverticulectomy without dacryocystorhinostomy was performed because of lacrimal drainage system patency. At 6 months' follow-up the patient remained asymptomatic.
