H. (Cairo, Egypt). Endoscopic transnasal surgery in chronic maxillary sinusitis [Elektronische Daten] [R. H. Kamel] The treatment of chronic maxillary sinusitis aims at the re-establishment of proper aeration and drainage of the antrum. Middle meatal antrostomy offers ventilation and clearance of the antrum and has anatomical, physiological, physical and pathological basis. This work included 66 cases of chronic maxillary sinusitis, for whom 94 operations of endoscopic middle meatal antrostomy were performed (38 unilateral and 28 bilateral procedures). Any associated anatomical variations and/or pathological abnormalities at the ostiomeatal area were dealt with. Follow-up of these cases for periods ranging from four to 12 months showed that 95.5 per cent of the cases experienced subjective improvement. Endoscopically 96.8 per cent of the antrostomies were patent and 94.7 per cent of the maxillary sinuses were clear and regained healthy mucosa. The author concluded that middle meatal antrostomy, when done endoscopically, is a safe procedure with good results Copyright © JLO (1984) Limited 1989 The Journal of Laryngology & Otology Cambridge University Press 103/5(1989-05), 492-501 0022-2151 103:5<492 1989 103 JLO https://doi.org/10.1017/S0022215100156701 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1017/S0022215100156701 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Kamel R.
