Purpose: Orbital apex syndrome due to spread of infectious sinusitis is a serious disease, often with an insidious presentation with few ophthalmic signs and symptoms. Failure to recognize and treat infectious orbital apex syndrome early portends a grave prognosis, including profound, permanent visual loss and potentially death. Herein we describe a representative case and discuss the relevant aspects of prompt diagnosis and treatment. Observations: An unusual case of infectious orbital apex syndrome due to contiguous spread of Streptococcus viridans sphenoethmoiditis in a hospitalized, immunosuppressed patient with acute myelogenous leukemia is presented...

A 64-year-old man presented with a 3-month history of diplopia and left-sided proptosis. Examination was significant for impairment of his left second, third, fourth, fifth, sixth and seventh cranial nerves. Magnetic resonance imaging revealed a left orbital apex and cavernous sinus lesion. However, subtle thickening of his left frontal and supraorbital nerve was not identified until later. A trial of steroids provided minimal effect. Biopsy of the lesion showed a well-differentiated squamous cell carcinoma...

PURPOSE: The inferior oblique muscle branch of the oculomotor nerve is susceptible to injury during orbital fat removal from the inferolateral quadrant of the orbit. Understanding the amount of removable orbital fat volume in this quadrant may be helpful in achieving maximum fat decompression without causing nerve injury. The aim of this study was to calculate the orbital fat volume in the inferolateral quadrant using computed tomographic (CT) images. METHODS: In this retrospective, observational study, contiguous 1-mm coronal CT images were obtained from 53 sides (30 patients)...

IQ·SPECT (Siemens Medical Solutions) is a solution for high-sensitivity and short-time acquisition imaging of the heart for a variable angle general purpose gamma camera. It consists of a multi-focal collimator, a cardio-centric orbit and advanced iterative reconstruction, modeling the image formation physics accurately. The multi-focal collimator enables distance-dependent enlargement of the center region while avoiding truncation at the edges. With the specified configuration and a cardio-centric orbit it can obtain a fourfold sensitivity increase for the heart at the center of the scan orbit...

BACKGROUND: Few studies have established surgical landmarks for endoscopic endonasal dissection of the intraconal orbital apex (OA). OBJECTIVE: We describe the optic nerve (ON) anatomy and its relationships, as seen during a fully endoscopic, endonasal approach to the medial intraconal OA. METHODS: The study question was approached through a cadaver dissection and a radiographic study. Four formalin-fixed, latex-injected cadaver heads were dissected using transnasal endoscopic techniques...

Sarcoidosis is an autoimmune granulomatous disease that can affect any organ system in the body. Ocular and orbital manifestations are relatively common. Osseous involvement is rare and usually involves bones of the appendicular skeleton. We present an unusual case of an erosive sarcoid granuloma in a 48-year-old woman that involved the orbital apex. This case highlights diagnosis, treatment, and the importance of full systemic workup to determine the extent of the disease.

Disorders affecting the equine maxillary cheek teeth and paranasal sinuses are relatively common, but limited objective information is available on the dimensions and relationships of these structures in horses of different ages. The aims of this study were to assess age-related changes in the positioning and anatomical relationships of the individual maxillary cheek teeth with the infraorbital canal and maxillary septum and the volumes of the individual sinus compartments. CT and gross examination were performed on 60 normal equine cadaver heads that were aged by their dentition...

Orbital apex syndrome is rare, but can occur as a consequence of trauma from fracture of the medial orbit. This case report highlights the fact that a high index of suspicion is needed when a patient presents with a facial injury, especially in children who cannot give an account of the actual events that transpired. Radiological investigation should be done early when an underlying injury is suspected in a trauma patient. A low threshold for computed tomography should be maintained when proptosis and vision loss are present...

Sphenoorbital meningiomas (SOMs) are slow-growing tumors that originate from the sphenoidal wing and are associated with visual deterioration, extrinsic ocular movement disorders, and proptosis caused by hyperostosis of the lateral wall of the orbit. In some cases, the intracranial component is quite small or "en plaque," and the majority of the symptoms arise from adjacent hyperostosis. Craniotomy has traditionally been the standard of care, but new minimally invasive multiportal endoscopic approaches offer an alternative...

The authors describe the surgical anatomy for the endoscopic endonasal approach (EEA) to the ventrolateral skull base. The ventrolateral skull base can be divided into two segments: the upper lateral and lower lateral skull base. The upper lateral skull base includes the cavernous sinus and the orbit, while the lower lateral skull base includes the petrous apex, Meckel's cave, parapharyngeal space, infratemporal fossa, etc. To gain access to the upper lateral skull base, a simple opening of the ethmoid sinus provides sufficient exposure of this area...

There are various causes that can lead to compressive optic neuropathy. We present here orbital apex cyst as an unusual cause of compressive optic neuropathy in a 49-year-old male. He presented with 2 weeks painless loss of vision in the left eye with left-sided headache. He had had left functional endoscopic sinus surgery for left nasal polyps 4 years earlier. Magnetic resonance imaging of brain and orbit revealed a left discrete orbital nodule, possibly orbital cyst or mucocele, which was compressing on the left optic nerve...

Efficient and rapid access to nanographenes and π-extended fused heteroaromatics is important in materials science. Herein, we report a palladium-catalyzed efficient one-step annulative π-extension (APEX) reaction of polycyclic aromatic hydrocarbons (PAHs) and heteroaromatics, producing various π-extended aromatics. In the presence of a cationic Pd complex, triflic acid, silver pivalate, and diiodobiaryls, diverse unfunctionalized PAHs and heteroaromatics were directly transformed into larger PAHs, nanographenes, and π-extended fused heteroaromatics in a single step...
