Editor,
I read the paper by Liao et al with interest. It is indeed one of the biggest studies of mitomycin C in external DCR. I have few queries about how mitomycin C was applied. Firstly, where should the pledget of mitomycin C be placed if the posterior flaps of the nasal mucosa and the sac are not sutured? My practice is to take a U-shaped flap of both the nasal mucosa and the lacrimal sac. Secondly, how is the cotton pledget removed after the 30 mins? Is it removed endoscopically?
