Nasal septal deformities in chronic rhinosinusitis patients: clinical and radiological aspects.

Septal deformities are very frequent in patients suffering from chronic rhinosinusitis (CRS). The question is whether or not some types of septal deformities are involved more frequently in this process or not. The authors observed the incidence of particular types of septal deformities in a group of CRS patients using Mladina classification.

Pre- and postnatal ultrasound and magnetic resonance imaging of intracranial extra-axial glioneuronal heterotopia.

Glioneuronal heterotopias are rare malformations composed of differentiated derivates of neuroectodermal tissue that include disorganized neuronal and glial cells. They are typically located extracranially. The nasal cavity represents the most common location.

Blindness after reduction of facial fractures.

Blindness in patients suffering maxillofacial trauma is usually caused by optic nerve or optic canal injuries. It is, however, an uncommon complication of facial trauma, with a reported incidence of only 2 to 5 percent. Blindness may also follow surgical repair of facial fractures.

Blindness as a complication of Le Fort osteotomies: role of atypical fracture patterns and distortion of the optic canal.

Blindness in patients suffering maxillofacial trauma is usually caused by optic nerve or optic canal injuries. It is, however, an uncommon complication of facial trauma, with a reported incidence of only 3 to 5 percent. This incidence drops dramatically when fractures are performed in the controlled situation of orthognathic surgery.

Sound- and/or pressure-induced vertigo due to bone dehiscence of the superior semicircular canal.

Objectives: To present symptoms, patterns of nystagmus, and computed tomographic scan identification of patients with sound- and/or pressure-induced vertigo due to dehiscence of bone overlying the superior semicircular canal. To describe anatomical findings and outcome in 2 patients undergoing plugging of the superior semicircular canal for treatment of these symptoms.

Design And Setting: Prospective study of a case series in a tertiary care referral center.

Advantages and disadvantages of three-dimensional computed tomography intraoperative localization for functional endoscopic sinus surgery.

Intraoperative three-dimensional computed tomography (3-D-CT) localization has been available for use during functional endoscopic sinus surgery (FESS) for several years, although relatively few otolaryngologists operate in conjunction with this technology. Proponents of intraoperative localization believe that operating with stereotaxis enhances surgical precision and reduces complications. A 1-year review was conducted at the University of Pennsylvania from January 1994 through January 1995.

Imaging of inflammatory sinus disease.

Sinusitis, especially as it relates to allergies, is one of the most commonly overlooked and misunderstood diseases in clinical practice. This article explores the radiographic appearance and anatomic characteristics that must be considered in the diagnosis and treatment of sinusitis. CT scans and MR imaging also are discussed in relation to the diagnosis of this disease.

Sinusitis in HIV-infected patients: a clinical and radiographic review.

Purpose: To describe the clinical, radiographic, and laboratory features of sinus disease in human immunodeficiency virus (HIV)-infected individuals.

Patients: Seventy-two patients with a history of sinusitis identified from 1,461 consecutive admissions (667 patients) to the HIV ward at The Johns Hopkins Hospital.

Methods: Retrospective chart review.

Neonatal diagnosis of a presacral mass in the presence of congenital anal stenosis and partial sacral agenesis.

The simultaneous presentation of clinically symptomatic anal anomalies and roentgenographically demonstrated sacral dysgenesis should alert the pediatric surgeon to investigate for the presence of a presacral malformation. We report on such a case to illustrate a new radiographic technique that facilitates diagnosis and management of complex congenital malformations. A 1-day-old white boy presented with anal stenosis, a scimitar-shaped sacrum, and large anterior and posterior meningoceles.

Patency of the internal jugular vein after functional neck dissection.

The objective of this study was to determine the immediate patency rate for internal jugular veins preserved in functional neck dissections. Thirteen patients had contrast-enhanced CT scans 2 to 4 weeks postoperatively. Ten veins were patent and had a diameter comparable to that seen on the preoperative scan; one vein was narrowed but patent; two were occluded.

Percutaneous trephine bone biopsy of the thoracic spine.

The authors performed six consecutive percutaneous trephine biopsies of the thoracic spine under local anesthesia, using computed tomography to localize lesions and guide needle placement. The details of the technique are illustrated. Complications were not found.
