Flexible endoscopy is assuming a role of increasing importance in the evaluation and diagnosis of upper aerodigestive tract disorders. With improved fiberoptic capabilities and miniaturization, these techniques are gaining in applicability to the pediatric population. ⋯ Our experience with the flexible fiberoptic minibronchoscope is reviewed, with a discussion of indications for its use, as well as possible limitations. Case studies are presented to demonstrate the usefulness of the instrument.

A 58-year-old man was evaluated for a 42-year complaint of a pharyngeal foreign body sensation whenever he ate. Examination revealed normal anatomy at rest but diffuse hypopharyngeal distension with Valsalva's maneuver. His past history was remarkable for an infectious illness, possibly diphtheria. We speculate that this unusual case most likely represents a postdiphtheritic selective pharyngeal paralysis and present his case, radiographic findings, and a discussion of the differential diagnosis.

Stroboscopic evaluation for the analysis of laryngeal function and disease has been reemphasized recently and its routine clinical use recommended. Many have found, however, that it is not always possible to obtain consistently satisfactory video images of stroboscopic laryngoscopy. ⋯ The cameras included 1) single tube camera, 2) single chip metal oxide semiconductors (MOS) solid-state camera, 3) single chip charge-coupled devices (CCD) solid-state camera, 4) three-tube camera, and 5) three-chip CCD camera. Currently available video cameras and their adaptability for stroboscopic videolaryngoscopy are discussed.

Giant cell arteritis and polymyalgia rheumatica. Review for the otolaryngologist.
Patients suspected of giant cell arteritis or polymyalgia rheumatica are often referred to the otolaryngologist for temporal artery biopsy. These patients may initially present to the otolaryngologist with symptoms referable to the head and neck. A comprehensive review of these two interrelated disorders is provided, with emphasis on head and neck manifestations and features of obtaining the temporal artery biopsy specimen.

Comparative StudyFlexible laryngoscopy in neonates, infants, and young children.
Flexible laryngoscopy was performed 453 times on 264 patients 4 years of age or younger. Sixty-five percent were under 6 months of age. Stridor was the indication for laryngoscopy in 60% of the patients. ⋯ The most common finding was laryngomalacia, followed by laryngeal edema, normal larynges, and vocal cord paralysis or paresis. Subglottic stenosis was diagnosed in 17 patients. Flexible laryngoscopy is a relatively noninvasive, safe, and effective technique for examining the larynx of infants and young children.
