Endoscopic Endonasal Sinus Surgery: A Long-term Follow-up Study

Abstract

This study presents 230 patients who have been selected for endoscopic endonasal sinus surgery on the basis of a standardised diagnostic procedure. Surgery was performed by one surgeon during the period 1987 to 1991 and the Messerklinger technique (MT) was used exclusively. the selection was made from patients with nasal/paranasal complaints remitted for further treatment. Diagnostic procedures comprised a thorough anamnesis including questions about additional factors such as specific allergy of the upper airways, unspecified hyperreactivity of the nasal/paranasal mucosa, asthma, smoking, exposure to air pollution, heritage and systemic diseases, in addition to a conventional ENT-examination, endoscopy of the nasal/paranasal cavities, and tomography (conventional or computed). the patients were thereafter divided into the following groups: 1) acute recurrent and/or chronic sinusitis, 2) nasal/paranasal polyposis, 3) sinogenic headache, 4) mucoceles, and S) olfactory dysfunction. More than 90% of the patients were treated on a day care out-patient basis, under local/topical anaesthesia combined with intravenous sedation. the extent of surgery varied in the different groups. There were no serious peroperative complications and no postoperative sequelaes. the patients were closely followed postoperatively for 1-5 years (mean 3 years and 5 months) until the study was closed at the end of 1992. We conclude that endoscopic endonasal sinus surgery demands several postoperative controls. Meticulous postoperative care is one of the basic requisites for securing optimal long-term results.
