Surgical technique of the supraorbital key-hole craniotomy.

2003

BACKGROUND The enormous development of microsurgical techniques and instrumentation together with preoperative planning using the excellent preoperative diagnostic facilities available, enables neurosurgeons to treat more complicated diseases through smaller and more specific approaches. METHODS The technical details of the supraorbital key-hole craniotomy are described in this article as it has been evolving in our experience for more than 10 years. After an eyebrow skin incision with careful soft tissue dissection and single frontobasal burr-hole trephination, a supraorbital craniotomy is carried out with a diameter of about 1.5 x 2.5 cm. As a real frontolateral approach, the supraorbital…

Color Doppler imaging of the eye and orbit A synopsis of a 400 case experience

2009

Color Doppler imaging (CDI) is a recent advance in ultrasonography that allows simultaneous two-dimensional imaging of structure and blood flow. Doppler information is superimposed in color over a conventional gray-scale ultrasound image. Using this technique we have examined 400 eyes. The central retinal artery, posterior ciliary arteries, ophthalmic artery, the central retinal vein and the vortex veins could be located in all normal eyes. Using the color image as a guide, Doppler spectral analysis is used for quantitative assessment of blood flow velocity in these vessels. We also studied patients with intraocular tumors, arterial and venous retinal occlusions, orbital vascular anomalies …

Update in minimally invasive periorbital rejuvenation with a focus on platelet-rich plasma: A narrative review.

2020

Background The periorbital region is among the first areas to be affected by the process of aging, which is influenced by genetic and constitutional factors. As the region plays an important role in overall facial appearance, rejuvenation of the area has immense cosmetic benefit and various treatment modalities have been used to achieve the same. Aims This article reviews commonly used non-surgical and minimally invasive modalities for periorbital rejuvenation. Methods The literature research considered published journal articles (clinical trials or scientific reviews). Studies were identified by searching electronic databases (MEDLINE and PubMed) and reference lists of respective articles.…

The 2016 European Thyroid Association/European Group on Graves' Orbitopathy Guidelines for the Management of Graves' Orbitopathy

2015

Graves' orbitopathy (GO) is the main extrathyroidal manifestation of Graves' disease, though severe forms are rare. Management of GO is often suboptimal, largely because available treatments do not target pathogenic mech anisms of the disease. Treatment should rely on a thorough assessment of the activity and severity of GO and its impact on the patient's quality of life. Local measures (artificial tears, ointments and dark glasses) and control of risk factors for progression (smoking and thyroid dysfunction) are recommended for all patients. In mild GO, a watchful strategy is usually sufficient, but a 6-month course of selenium supplementation is effective in improving mild manifestations …

Plain film, CT and MRI sensibility in the evaluation of intraorbital foreign bodies in an in vitro model of the orbit and in pig eyes.

2000

Detection and characterization of intraorbital foreign bodies (IFB) is fundamental in acute trauma setting, preventing inflammatory sequelae or complications related to IFB movements when a MRI study is planned. Papers concerning plain film and CT sensibility in IFB detection show controversial results. For this reason we investigated plain film, CT and MRI sensibility in the evaluation of IFB. For an in vitro model, specimens of dry and fresh wood, glass, iron, plastic and graphite were immersed in animal lard and in a 0.9 % sodium chloride plus 3.5 g/dl human serum albumin solution. Specimens of different size and nature where also implanted into enucleated pig eyes. Air bubbles were intr…

Somatostatin-Rezeptor-Szintigraphie bei endokriner Orbitopathie

1994

Somatostatin receptor scintigraphy with 111In-labeled octreotide proves to be a very sensitive diagnostic tool for evaluation of inflammative activity in endocrine ophthalmopathy (EO). The results of somatostatin receptor scintigraphy (SRS) in 40 patients with EO show a high orbital accumulation of 111In-octreotide in clinically active EO (4 h-median/orbit-brain-ratio: 12.6; controls 4 h-median: 5.8) Patients with clinically inactive EO (4 h-median: 7.1) show a similar orbital accumulation of radioactivity compared to controls. 5 patients with active orbital myositis also revealed an even higher orbital accumulation of radioactivity (4 h-median: 42.3). The diagnostic value of SRS lies in it…

Patients' cosmetic satisfaction, pain, and functional outcomes after supraorbital craniotomy through an eyebrow incision

2014

Object The supraorbital approach through an eyebrow incision offers the opportunity to access a wide variety of lesions of the anterior, middle, and even the posterior fossa. The minimally invasive keyhole craniotomy limits brain exploration and retraction and offers the potential for improved surgical outcomes and reduced approach-related complications. Patient satisfaction, however, has not yet been reported in the literature. Methods From January 2002 through December 2011, the lead author (R.R.) used a supraorbital approach through an eyebrow incision for 418 patients with cerebral aneurysms, brain tumors or cystic lesions, and other miscellaneous pathological conditions. For 408 of th…

Radiotherapy for Graves’ ophthalmopathy

2000

The interest in the treatment of benign diseases with radiation therapy has grown particularly in the Western part of the world. In 1996, a questionnaire was sent to 1348 institutes worldwide listed in the directory of the Society for Therapeutic Radiology and Oncology asking whether the respondents considered a list of 28 most common benign disorders as being a good indication for orbital radiotherapy.1 Questions concerned the frequency of such treatments and the treatment schedules used. The prevention of keloid formation was the most widely accepted indication, followed by Graves’ ophthalmopathy. Thus, radiotherapy for this orbital disorder is generally accepted and applied worldwide.
