Air contrast tube esophagram: technique and clinical examples. Technical note.

The air-contrast tube esophagram is performed by positioning a soft thin rubber catheter in the proximal esophagus. The patient drinks high density, low viscosity barium while the esophagus is insufflated with air through the tube. The procedure can usually be completed in five to eight minutes. In the majority of patients there is minimal discomfort. The advantage of the tube esophagram is the fact that it provides reliable, uniform full-column air distention.

A bloodless technique for tongue surgery.

The Cavitron Ultrasonic Surgical Aspirator (CUSA System) has been used at our institution in the resection of carcinoma of the tongue in 10 patients. This device is an ultrasonically powered aspirator that selectively fragments and aspirates tissue within a 1- to 2-mm radius of its tip. The technique used in our unit in tongue surgery was to incise the touch mucosal capsule of the tongue with electrocautery, and then to divide muscle and skeletonize blood vessels using the CUSA System. Smaller vessels, up to 2 mm in size, were cauterized directly by the friction created at the tip of the instrument. In this way, excellent control was available at all times and blood loss was consequently minimal. As our experience in the use of the CUSA System increased, blood loss was virtually eliminated, anatomic landmarks were more easily defined, and at no stage did any tongue necrosis occur in any of the patients of the series.

Oral congenital cystic choristomas: a case report.

Solitary choristomas containing gastrointestinal mucosa occur rarely in the tongue and the oral mucosa and usually present as an asymptomatic mass. This report documents the occurrence of two congenital intraoral cystic choristomas in a 5-month-old male infant. The cysts were located on the dorsum of the base of the tongue and left floor of mouth anterior to the lingual cyst. Both cysts were lined by nonkeratinizing squamous epithelium and gastric, intestinal, and respiratory epithelium. The cysts were excised by an oral approach.
