[Personal experience with sinus endoscopy. Apropos of 120 cases of chronic sinusitis]

One hundred and twenty adults have benefitted from a full staging of their chronic maxillary sinusitis. The authors detail the place of endoscopy in the assessment and management of the different clinical presentations. The endoscopy will be useful only if a systematic examination is performed, of nose and paranasal cavities, both optically and manometrically. Nature and severity of the disease can be evaluated by summarizing of the patient findings of story, clinical, radiological examinations and biological data. Endoscopy constitutes nor a valuable diagnostic tool, nor a therapeutic approach, conducting conservative treatment and avoiding some radical surgery.
