Green R, et al. - Experts conducted a systematic review and critical evaluation of the evidence relating to the preservation of nasal mucosal flaps in dacryocystorhinostomy (DCR) surgery. Findings suggested a poor overall quality of current evidence. Nonetheless, in groups where nasal mucosal and lacrimal flaps were preserved, a trend towards improved outcomes and reduced granulation was seen, but this is not clear-cut. Authors did not note an evidence of increased complication rates with mucosal-sparing techniques. While performing DCR routinely, a mucosal-sparing technique should be performed until further good quality research is available.
