Orbital complications of pediatric sinusitis: treatment of periorbital abscess.
1997
Twenty-six children requiring surgical intervention for orbital complications of acute sinusitis were treated at our institutions between 1985 and 1995. Twenty patients were successfully treated surgically utilizing endoscopic/microscopic endonasal surgery, or traditional external ethmoidectomy. However, six patients failed to respond to initial surgical attempts and ultimately required a revision. In one of these six patients the development of an intracranial abscess also necessitated a craniotomy for surgical drainage. Analysis of these six failures was performed with special attention given to the reasons for initial surgical failure and possible means for preventing revision surgeries…
Is there a relationship between the degree of preoperative motility impairment or the muscle thickness and the outcome of strabismus surgery in patie…
2005
There is considerable controversy regarding the performance of strabismus surgery in patients with Graves' orbitopathy (GO). The spectrum of recommendations extends from variable dose-effect correlations for these procedures (Esser, 1994; Mourits et al., 1990; Nguyen et al., 2002) to individualized approaches such as passive intraoperative motility testing and postoperative adjustment of sutures (Lueder et al., 1992; Nguyen et al., 2002), and to local anesthesia for intraoperative assessment of active motility (Kalpadakis et al., 2004). Furthermore, prior decompression surgery is known to contribute to an unpredictable outcome (Eckstein and Esser, 2003; Esser, 1994). We retrospectively anal…
A sphenoorbital encephalocele — clinical, radiological, and morphological findings
1988
We report here on congenital sphenoorbital encephalocele which could not be disclosed by computed tomography including contrast medium application or by orbital sonography. Surgery and histological examination were necessary to establish correct the diagnosis.
Echographic patterns of an orbital myxoma and schwannoma
1988
A case of intramuscular orbital myxoma and of a schwannoma of the orbit were studied with B-scan and standardized A-scan echography as described by Ossoinig. The myxoma appeared as a well outlined process with medium internal reflectivity and areas of low internal reflectivity. Postoperatively the incompletely excised tumour was followed with echography as well as CT and MRI. The second tumour, a schwannoma had a very sharply defined shape, with a thick low to medium reflective outer wall and low internal reflectivity. This corresponds to the Antoni A and Antoni B patterns of the excised tumour.
Sonography and computed tomography in the diagnosis of orbitocranial malformations and tumors
1987
Standardized sonography and CT scanning have distinct advantages and disadvantages in the evaluation of patients with orbital diseases. Echography provides an efficient screening examination in patients presenting with signs and symptoms of orbital pathology. It allows the detection, localization, measurement and in almost 80% differentiation of orbital lesions. High resolution CT scanning gives an excellent topographic display of masses in the orbit. In visualization of intracranial causes of orbital processes and demonstration of changes in the posterior third of the orbit, in the orbital bones and the periorbital sinuses it is superior to ultrasonography.
The electrofunctional investigations in the diagnosis of orbital diseases
1983
The importance of electrofunctional examinations (electroretinography, electro-oculography and visual evoked potentials) in orbital diseases is emphasized. Although such tests cannot give the same support to the clinical diagnosis as ultrasonography or CT scanning, they do give information about the functional state of the various orbital components. Visual evoked potentials can monitor the functionality of the optic nerve during and after trauma or compressive orbital diseases; electroretinography shows retinal changes secondary to traumatic or vascular orbital diseases, while electro-oculography allows to record extraocular muscle dysfunction.
