PURPOSE: To present a new surgical technique for excision of orbital cavernous hemangiomas (CHs). METHODS: This retrospective case series study included patients with orbital CH who were operated from 2001 to 2016 at our referral center. Epidemiologic data, symptoms, signs, and images were reviewed from patients' files with at least one year of follow-up. Surgical results and complications were documented. We used the "index finger dissection" technique without grasping the tumor for release of adhesions and its removal...

Introduction: Inverted papilloma is a locally-aggressive benign neoplasm of the paranasal sinuses with a high potential for recurrence and malignancy. Intracranial extension is infrequent, and dural penetration even more so, typically associated with recurrence of the disease or its degeneration into squamous cell carcinoma. Clinical Case: A 32-year-old female patient consulted us for an exophytic lesion in her right nostril and exophthalmos, associated with headache, anosmia and dysgeusia...

3D printing is a kind of technology that makes 3D models from computer-aided designs through additive manufacturing, in which successive layers of the material are deposited onto underlying layers to construct 3D objects. In recent years, 3D printing is gradually applied in the field of ophthalmology, such as the cornea, retina, orbital operation, ocular tumor radiotherapy, ocular implants and ophthalmology teaching. This article reviews the application status of 3D printing technology in the basic research and clinical treatment in ophthalmology...

OBJECTIVES: Functional venous anatomy in the brain has been mostly understood from the morphological and embryological points of view and no published study has directly evaluated the blood flow volume of cerebral small veins. We developed a method to directly evaluate the relative blood volume in small venous channels using multi-detector computed tomography (CT) and applied it to evaluate the blood volume in each tributary of the cavernous sinus, which plays an important role in cerebral venous drainage...

Orbital schwannomas are characteristically slow-growing benign tumors arising from peripheral sensory nerves. However, the authors' case illustrates the atypical presentation of such a tumor.A 71-year-old male presented with proptosis, visual loss, and periorbital inflammation. Sequential imaging showed continuous and rapid growth of an intraconal mass arising from the medial rectus. Excision of the mass was performed and it was histopathologically proven to be an orbital schwannoma.This patient demonstrates the atypical presentation of an orbital schwannoma, arising from an extraocular muscle with rapid progressive growth and inflammation, indicating it should be considered a differential diagnosis in orbital masses presenting as such...

Cavernous hemangiomas are the most common tumors of the posterior cone of the orbit in adults. They are discovered in a fortuitous manner or in front of the appearance of a progressive exophthalmia.The authors report through a complete literature review (PubMed) patients of retro-orbital cavernous hemangioma revealed by spontaneous compressional hemorrhage from 1984 to 2017.This review is illustrated by a case of sharp decrease in visual acuity secondary to orbital cavernous hemangioma hemorrhage.The authors detail the management and the evolution of all these patients...

Devin Ruiz, Elie E Rebeiz
INTRODUCTION: Venous malformation is a common tumor of the orbit, presenting with visual impairment and proptosis. These lesions can be excised via an external or transcranial approach, but recent advances in minimally invasive surgery have led to increased popularity of endoscopic approach. PATIENT: The authors report a 62-year-old female presenting with diplopia and proptosis, found to have a 1.7-cm venous malformation of the orbital apex. An endoscopic trans-nasal approach was undertaken for surgical resection...

Background: Retinoblastoma (Rb) is the most common primary intraocular tumor of infancy and childhood. Survivors' ocular and visual problems and increased risk for subsequent malignancy are well documented, but data on long-term health status of Rb survivors are limited, this being particularly true for India. Methodology: Children who had completed treatment for Rb at least 2 years ago before and were under follow-up at the after cancer treatment clinic were evaluated...

In this video clip, the authors present the resection of a tuberculum sellae meningioma with compression of the left optic nerve and a chiasm ( Fig. 1 ) through a standard cranial orbital (CO) skull base approach. 1 2 3 The key step in the tumor resection was microsurgical dissection of left and right A1 segments of the anterior cerebral artery and the anterior communicating artery and the separation of the tumor from these vascular structures. This was followed by careful separation of the meningioma from both optic nerves, the chiasm and the pituitary stalk...

Tuberculum Sellae Meningiomas (TSMs) are lesions dramatically related to the optic apparatus once the principal clinical complain remains on visual alterations. This is the main picture on decision making to evaluate the best time, risk-benefit, and surgical approaches to the patient treatment. In this video, we present a 65 years old female with 30 days complaint of unilateral (right) complete blindness and complete impaired right eye field test. On physical examination, there were normal pupillary function to light tests...

Unilateral suprasellar meningiomas have distinct features compared to other midline tumors, as they may produce severe visual symptoms even if small due to an early involvement of the optic canal. Surgical treatment of these tumors from an ipsilateral approach is challenging, as the tumor is covered by the optic nerve that needs to be mobilized to access the optic canal extension. A contralateral approach allows a direct line of sight to the tumor despite a longer working distance. We report the case of a 49-year-old patient presenting with unilateral visual loss related to a left suprasellar meningioma extending to the left optic canal and displacing the optic nerve laterally...

REVIEW

Introduction  Skull base lesions in children and adolescents are rare, and comprise only 5.6% of all skull base surgery. Anterior skull base lesions dominate, averaging slightly more than 50% of the cases. Until recently, surgery of the anterior skull base was dominated by open procedures and endoscopic skull base surgery was reserved for benign pathologies. Endoscopic skull base surgery is gradually gaining popularity. In spite of that, open skull base surgery is still considered the "gold standard" for the treatment of anterior skull base lesions, and it is the preferred approach in selected cases...

Inflammatory orbitopathies relate to an inflammatory state originating within the orbit and its adnexes, except the inner ocular globe. Orbital inflammation (OI) may be either localized manifestation of a proven or like autoimmune disease, or local response from immune system against infectious, structural or tumoral antigens. We review the clinical manifestations of OI, which provide helpful clues to the diagnosis and describe the inflammatory, infectious and neoplastic conditions classically associated with OI...

Fibrous dysplasia (FD) is a disturbance of the mesenchymal tissue that accounts for 2.5% of all bone tumors and more than 7% of nonmalignant bone tumors. In the craniomaxillofacial region, FD affects the calvaria, skull base, zygoma, and jaws, the prevalent site being the maxilla (50% of cases). Therapy for craniomaxillofacial FD is surgical. The goals of surgery are to prevent functional disorders and restore facial symmetry, volume, and contour. In this article, we present a case of a young female patient affected by right orbital-zygomatic-maxillary FD...

Dermoid cyst is an example of choristoma (i.e., tumors that originate from aberrant primordial tissue which result in normal appearing tissue in an abnormal location). This particular type of cyst is formed at the site where 2 suture lines of the skull close during embryonic development, and during this time, dermal or epidermal elements are pinched off which later convert to form cysts. Approximately, 50% of these tumors that involve the head are found in or adjacent to the orbit. This article presents a similar case of the orbital dermoid cyst with its management and also a review on other varieties of dermoid cysts of the head and neck region...

A 55-year-old woman with relapsing polychondritis had progressively enlarged right retro-orbital tumor invading the optic nerve, followed by left retrobulbar infiltrating lesions despite prescription of high-dose corticosteroids and pulse methylprednisolone. Repeated histopathologic analyses showed dense collagen fibers with scanty inflammatory cells, consistent with the diagnosis of idiopathic sclerosing orbital inflammation. This disorder has been recognized as a distinct entity with unique clinical features and coexisting rheumatologic disorders, requiring more focused diagnostic strategies and therapeutic regimens...

REVIEW
Lauren Crawford, Sanjeev Sharma
Orbital apex metastasis from adenoid cystic carcinoma (ACC) is rare. We present a patient with known metastatic ACC presented with a rapidly declining vision with visual acuity oculus dexter (OD) equal to counting fingers at two feet. On imaging, she was found to have a right orbital apex tumor causing compressive optic neuropathy. She received the intensity modulated radiation therapy (IMRT). After completion of the therapy, she had regained essentially a full vision with visual acuity OD of 20/30 without corrective lenses...
