Vocal cord augmentation with autogenous fat.

Since 1987, the authors have used a new technique for the augmentation and medialization of the paralyzed vocal cord. Eleven patients with paralyzed vocal cords and one patient with a surgical defect of the vocal cord have been treated with intracordal injections of autogenous fat harvested by suction from the abdominal wall. Treatment efficacy was evaluated by both subjective and objective (videostroboscopic) analyses.

An analysis of civil aviation propeller-to-person accidents: 1965-79.

The interest of manufacturing, governmental, and safety personnel in using paint schemes on propeller and rotor blades is based on improving the visual conspicuity of those blades when they are rotating. While propeller and rotor paint schemes may serve to reduce the number of fatalities and injuries due to contact with a rotating blade, there is little information about the circumstances surrounding such accidents. Brief reports provided by the National Transportation Safety Board of all "propeller-to-person" accidents from 1965-79 were examined and analyzed in terms of airport lighting conditions, actions of pilots, actions of passengers and groundcrew, phase of flight operations, weather conditions, and others.

Improving the crashworthiness of general aviation aircraft by crash injury investigations.

An aircraft accident investigation program correlates injuries to occupants with the severity of impacts and structural changes in the crash. Findings brought to the attention of aircraft manufacturers have led to specific aircraft being made more crash-worthy. The finding of a failure in a shoulder harness attachment led to the strengthening of the attachment brace.

Spatial disorientation in general aviation accidents.

Spatial disorientation (SD) was the third highest "cause" of fatal accidents in small, fixed-wing aircraft and closely related to the second highest "cause"--"continued VFR flight into adverse weather." SD was a cause or factor in 16% of all fatal accidents. When SD was ascribed as a cause or factor in an accident, 90% of the time that accident involved fatalities.

Actinomycosis of the larynx and pharynx.

This paper presents a case report of a 67-year-old man who was seen in the Otolaryngology Clinic, University of Wisconsin Medical Center with a seven-month history of dyspnea and laryngeal stridor. On examination there were several slightly tender firm submucosal nodules in the soft palate and left tonsilar area and a 1.5-cm polypoid subglottic mass arising from the body of the cricoid cartilage.
