[How good is the inferior meatal antrostomy in chronic maxillary sinusitis? (author's transl)]

44 inferior meatal antrostomies in 32 patients with chronic maxillary sinusitis were followed at two month intervals over a period of two years. Closure of the antrostomy occurred in 29.4% of the cases reported. Allergy was unimportant for the operative result, nor was an increased frequency of infections demonstrated following surgery. Subsequently, improvement of sinusitis was noticable, even after closure of the fenestration. In contrast to other reports in the literature, mucociliary drainage from the maxillary sinus to the nose occurs through the operatively placed fenestra.
