Documentation in pediatric laryngology.

Endoscopy in pediatric laryngology continues to develop and broaden its horizons. The need for documentation of the various pathological conditions has become more apparent. The upper lateral airways radiological study together with endoscopic photography allows permanent objective documentation of the changes occurring in any part of the upper respiratory tract from the nose and nasopharynx to the bronchi and segmental openings. This combination of radiological study and single frame color photography is the most convenient means of studying the pathology, natural history, and results of treatment as well as for clinical research and teaching in training programs.
