This is the most up-to-date reference depicting surgical anatomy, and thus fulfils an important need. It presents a step-by-step surgical approach from the anterior nasal spine to the anterior wall of the sphenoid, illustrated by brilliant colour photographs. Four critical anatomical structures are emphasised as the foundation for a precise approach to surgery of the maxillary, anterior ethmoid, frontal, and posterior ethmoid sinuses. In short, an anatomical approach which will serve the sinus surgeon at every level of experience and expertise.
