Meyers is good for describing the operation and relevant anatomy.
Janfazza is a solid H&N anatomy textbook with some clinical correlation in side notes throughout the text. I bought this text in residency.
Agreed that the best way is with subspecialty texts that go into far more detail and offer more relevance to the practicing ENT and resident. Your department should have most available for you to borrow on a short term basis - liase with your senior residents and residency director.
