Ottoni de Rezende84 reviews the various surgical procedures usually employed in the treatment of chronic sinusitis, without offering any critical evaluation except to point out the widespread use of the transantral ethmoid operation described by Ermiro de Lima, which in South America has yielded satisfactory results.Citelli85 states that the difficulties attending operation on the frontal sinus, so far as permanent cure is concerned, are inherent in the usual anatomic conformation of the sinus. Radical procedures envision complete removal of all diseased lining and the establishment of an adequate permanent opening into the nasal cavity. This can be done in the maxillary and the sphenoid sinus with comparative ease but presents a problem in the case of the frontal sinus. The author has been successful in achieving a permanent cure through maintenance of an external opening into the sinus near the internal angle to permit ventilation and irrigation
