BACKGROUND: Currently most ENT surgeons advocate using cutting instruments in Functional Endoscopic Sinus Surgery (FESS), based on the assumption of superior wound healing due to mucosal preservation. However, there is no scientific evidence of superiority of the cutting instruments. METHODS: A prospective, randomized double blinded study was performed in 100 patients undergoing FESS, operated one side with non-cutting and the contra lateral side with cutting instruments. After a mean follow-up of 12 years after FESS, unilateral and global sino-nasal symptoms were scored by the patients using VAS, endoscopic abnormalities scored at both sides at the Outpatient clinic and radiologic abnormalities were described. RESULTS: No significant differences between the sides operated by cutting and non-cutting instruments were found for sino-nasal symptomatic or for radiologic abnormalities between both sides. For the endoscopic parameters there was no difference for secretion or mucosa. Only for the presence of endoscopic synechiae there was a statistically significant difference between both groups. At the non-cutting side more synechiae were noticed, but no interference with sinus access, neither ventilation nor drainage was observed. CONCLUSION: FESS performed with cutting instruments results in less synechiae formation compared to non-cutting instruments. However, the presence of synechiae is not associated with more symptoms or CT scan abnormalities.
