title: [Heerman's principle in microsurgery of nasal cavity and paranasal sinuses].
abstract: Forty-year experience in surgical activity of an otorhinolaryngological department of A. Krupp's hospital in Essen, Germany, is reviewed. Main lines of Heerman's conception are shown in conduction of surgical interventions on the nasal cavity and paranasal sinuses, lacrimal tracts. Various endonasal interventions are performed with employment of endoscopes and surgical microscopes except malignant tumors, oroantral fistulas, malformations. The necessity of gain of surgical skill while operating corpses is emphasized.
