Sir, We read the above-referenced article by Amano et al.[1]. The authors have discussed the use of sphenoid sinus mucosa either as a free flap or as a vascularized pedicled flap for reconstruction of the meningeal defects created following surgery for pituitary tumors. It is indeed surprising that the authors have not found my article on their literature search that discusses the technique of use of sphenoid sinus mucosal flaps for reconstruction after transsphenoidal surgery for pituitary tumors [2]. My article has been published in a prominent journal and is available in all major search indices. I wish that the authors acknowledge this misrepresentation of facts that has the potential of affecting future publications that can be based on this article.
