Abstract
The majority of studies have shown that the use of functional endoscopic sinus surgery (FESS) leads to symptomatic improvement in 73-98.4 % of patients with chronic rhinosinusitis and nasal polyposis (NP). The aim of the study is to evaluate clinical outcomes and quality of life (QoL) in patients with NP after FESS. The prospective study included 85 consecutive adult patients (≥18 years) with NP who were operated on using FESS after failure of the medicamentous treatment and in certain cases of surgical treatment. QoL was assessed by Short Form-36 Health Survey (SF-36) questionnaire, and the symptom intensity was presented using visual analogue scale (VAS). The objective finding was presented as endoscopic and computerized tomography (CT) score. The intensity of each symptom, the values of symptom scores (major, minor and total), the values of dimension scales and summary scales of the QoL, as well as the values of endoscopic score through three periods of time (pre-surgery, 6 and 12 months after the surgery) were analyzed. Following the FESS, mean intensity values of all individual symptoms and symptom scores were significantly lower and the values of all dimension scales and summary scales of QoL were significantly higher (p < 0.05). There was no statistically significant difference in symptom intensity and QoL after 6 and 12 months of surgical treatment (p > 0.05). Endoscopic score was on average significantly lower after 6 and 12 months of FESS (p < 0.05), but the mean score value after 12 months of operation was significantly higher in relation to that after 6 months of surgery (p < 0.05). Nevertheless, the recurrence of NP was observed in 28 patients (32.9 %) in the follow-up period. In conclusion, FESS in NP patients results in significant improvement of symptom intensity, QoL and endoscopic score. While the intensity of symptoms and QoL showed a tendency to maintain between 6 and 12 months after surgery, endoscopic score showed a tendency of exacerbation in the same period.
