The importance of follow-up examinations in chronic rhinosinusitis with nasal polyposis

Purpose: Clinical examinations following functional endoscopic sinus surgery (FESS) for chronic rhinosinusitis with nasal polyps (CRSwNP) are critical for physicians to assess results of the intervention and to early identify recurrences. However, no clear consensus on the frequency and timing of clinical examinations following surgery exists. The aim of this study was to analyze CRSwNP recurrences after FESS with a specific focus on the adherence to follow-up examinations.Materials and methods: Sixty patients who underwent FESS for CRSwNP were enrolled. Clinical parameters were recorded. Adherence to follow-up examinations with nasal fiber optic endoscopy and regular administration of nasal steroids were analyzed.Results: Adherence to periodic clinical examinations and regular treatment with nasal steroids was 25 %. CRSwNP recurrence was observed in 56.7 % of cases at the last follow-up examination. No statistically significant difference concerning nasal symptoms was observed between patients with and without current recurrence (p > 0.05). Subjects who underwent regular examinations and prompt treatment of small recurrences had a lower probability of relapse at their last examination (7.7 % versus 38.2 %, respectively; p < 0.001). Polyp grade > 2 in patients with or without adherence were seen in 15.4 % and 42.9 % of cases, respectively (p < 0.05).Conclusions: Adherence to follow-up examinations with nasal optic fiber endoscopy is crucial to early identify recurrence after surgery and promptly treat it with medical therapy.
