OBJECTIVES/HYPOTHESIS Removal of the medial orbital wall for sinonasal tumor involvement is required to obtain complete oncologic resection. However, orbital fat herniation can produce significant morbidity, including enophthalmos and diplopia. The purpose of the current study was to evaluate outcomes following use of porcine small intestine submucosa (SIS) grafts for orbital reconstruction fol...

PURPOSE Orbital invasion of pituitary tumors is rare and usually accompanied by optic nerve head pallor and visual loss. We describe a case of unilateral massive orbital invasion by a recurrent pituitary tumor with preserved visual acuity and normal optic nerve appearance. METHODS Case report. RESULTS Progressive proptosis developed 15 years after transphenoidal removal of a pituitary tumor...

A 5-month-old infant with bilateral advanced retinoblastoma underwent six cycles of systemic chemotherapy. In an attempt to salvage the second eye, three serial injections of periocular carboplatin were given for persistent vitreous seeding. Following the third injection, the patient developed periocular ecchymosis and magnetic resonance imaging demonstrated abnormal signal characteristics at t...

UNLABELLED A 22-year-old male presented with proptosis of the right eye and diplopia. On magnetic resonance images (MRI), a well-delineated orbital tumor medio-distal to the eye was detected, respecting the eye-ball and the orbital walls. The aim of navigation-assisted surgery was to excise the progressive tumor while maintaining vision. A modified latero-cranial orbitotomy was used to approach...

Incidence of orbital tumor is -3.5-4%. Tumors and tumorlike lesions of the orbit in children represent a different histologic spectrum than in adults. In the pediatric population, a delay in diagnosis of orbital tumors, even if benign, can lead to vision loss and deformity. Purpose of this study is presentation of epidemiology, clinical signs and symptoms, frequency and histopathology of orbita...

  Background and Objective: Inflammatory pseudotumor  is a lesion composed of proliferating spindle cells with mixed inflammatory infiltrates. Some authors have proposed the name inflammatory myofibroblastic tumor as a proper descriptive term rather than the vague inflammatory pseudotumor. The aim of this study was to verify the myofibroblastic origin of spindle cells in idiopathic orbital inf...

Orbital defects after tumor resection (exenteration of orbital content) have been traditionally reconstructed with adhesive-retained craniofacial prostheses, also known as epistheses. The breakthrough in rehabilitation of facial defects with implant-retained prostheses has come with development of modern silicones (vynilpolysiloxane) and bone anchorage called osseointegration. Craniofacial impl...

The present study describes clinical manifestation, histopathologic findings and differential diagnosis of a first-reported case of giant chondroid syringoma (CS) of the upper nasal orbital rim. A 35-yr-old man with cranial palsy (CP) and a tumor of 3×3×4 cm in the upper nasal orbital rim of the left eye was referred to the eye clinic. The tumor was reported to have developed gradually over the...

CASE REPORT A six-year-old boy presented with proptosis of the right eye. Imaging studies detected a mass in the medial wall of the right orbit. This mass was biopsied revealing a histopathologic diagnosis of primitive neuroectodermal tumor, so chemotherapy treatment was given. After seven years in remission he presented with a recurrence of the orbital tumor and was found to also have systemic...
