Antroscopy in maxillary sinus disease associated with nasal polyposis.

Although the association of maxillary sinusitis with nasal polyps is widely recognized little has been written on its precise incidence and degree. Antroscopy of 70 antra with ipsilateral polyps showed a high incidence of mucosal abnormalities, retained secretions and ostial narrowing. Comparison of these findings with preoperative X-rays showed the latter were unreliable in detecting retained antral fluid. It is concluded that in nasal polyposis the antra warrant careful assessment and that antroscopy is a highly satisfactory method for this purpose.
