To the Editor:—
The apparatus described by Dr. Balatbat et al.  1 for applying lidocaine to the airway bears an uncanny resemblance to an arrangement that I first described in 1998. 2 I do appreciate, however, that it is not always easy to identify instances of previous publication, even with the most assiduous of literature searches, particularly if the publication in question happens to be correspondence. I say this with confidence because I made the same error myself; the arrangement was originally described by Dr. Tran in 1992. 3 Although others have judged my apparatus to be “more simple and ingenious” than that described by Dr Tran, 4 I suspect the same cannot be said for the arrangement described by Dr. Balatbat.
Whatever the merits of the various descriptions, it is worth emphasizing that the Tran-Mackenzie-Balatbat spray is a simple, elegant, and effective method for the topical application of drug sprays to mucosa-lined cavities, and is frequently adopted by those who have seen it in action, including otorhinolaryngologists.
