Abstract
Summary The objectives of this study are to detect impact of FESS for CRSwNP patients on QOL and evaluate how FESS modifies patients’ symptoms profile, to compare the QOL outcome before and after surgical intervention, and to assess and compare the effect of surgical treatment on nasal symptoms using subjective QOL questionnaires and endoscopic score system.
Consequently, we assessed the recurrence rate of sinonasal polyposis after functional endoscopic sinus surgery and we evaluated the role of some factors that affect recurrence rate including aspirin intolerance, asthma, and smoking.
Thirty patients with bilateral diffuse sinonasal polyposis not responding to medical treatment for at least six months were enrolled in the study. They were all scheduled for functional endoscopic sinus surgery and followed up for a period of twelve months. Pre-operatively, history was taken properly with special focus on smoking/aspirin sensitivity/asthma/ previous local polypectomy, Lund Kennedy scored endoscopic examination, and scored QOL questionnaires (SNOT 22/RSDI) were done. CT scans were performed by all patients enrolled in the study which were graded according Lund MacKay score system. All patients underwent FESS under general anasthesia and all operative surgeries were done by the same surgeon with the same technique to exclude the role of any surgical variation on the outcome of FESS to weigh properly the impact of the above-mentioned factors on the recurrence rate. Draf Ⅲ procedure/ septoplasty/inferior turbinate reduction were performed with the original endoscopic operation in some special cases. Lund Kennedy scored endoscopic examination and scored QOL questionnaires (SNOT 22/RSDI) were done for all patients at 3, 6, 12 months post-operatively.
In our prospective observational study nasal obstruction was the main presenting symptom (100%), followed by anosmia (63%), ear fullness (37%), anterior nasal discharge (33%), headache (20%), and posterior nasal drip (17%).
