A pilot study of autofluorescent endoscopy for the in vivo detection of laryngeal cancer.
To determine the advantage of autofluorescent endoscopy for the identification of laryngeal cancer. ⋯ Autofluorescent endoscopy is advantageous only in the hands of an experienced ENT specialist. Although it does not replace the combination of white-light endoscopy and a critical evaluation of the clinical symptoms of the individual disease, it can profitably complement them. Autofluorescent endoscopy can help in determining whether microscopic laryngoscopy performed with general anesthesia should be recommended urgently to the patient. Microscopic laryngoscopy remains the best method for the identification of malignant lesions, if it is combined with obtaining taking multiple biopsy specimens. Confirmation of the results of this pilot study with a larger series of patients is desirable.

Sleep disorders in general and obstructive sleep apnea syndrome in particular are prevalent health problems. This report describe the methodology and findings from a prospective multicenter outcomes research study on obstructive sleep apnea syndrome that was conducted by the American Academy of Otolaryngology-Head and Neck Surgery. Other outcome measures available for outcomes research in obstructive sleep apnea syndrome are also summarized.

Comparative Study
Role of laryngeal movement and effect of aging on swallowing pressure in the pharynx and upper esophageal sphincter.
Describe contribution of laryngeal movement to pressure changes at the upper esophageal sphincter (UES) and the effect of aging on the swallowing function. ⋯ The rapid superior and anterior movements of the hyoid bone are considered to start at the same time as those of the larynx. In the young group, it is suggested that superior laryngeal movement protects the lower airway prior to the anterior laryngeal movement, causing the pressure fall at the UES to enable the passage of a bolus into the UES. In the elderly, smooth passage of the bolus from the pharynx to the esophagus is hindered and the system that prevents aspiration is rendered inefficient by changes in the swallowing pressures and laryngeal movements with aging.

To identify changing trends in female authorship and publication in the otolaryngology literature. ⋯ There has been a significant trend toward increased female authorship in the otolaryngology literature. A significant portion of this is accounted for by nonphysician female authors, and female authorship tends to be concentrated in pediatric otolaryngology.
