This book presents a detailed investigation into rhinology, exploring the diagnosis and management of disorders affecting the nose and sinuses. It begins with the functional anatomy and physiology of this region, describing the nasal cavity’s role in respiration, filtration, and olfaction. The text explains the structure of the lateral nasal wall, the drainage pathways of the paranasal sinuses, and the mucociliary clearance system that serves as a primary defense mechanism. A central theme involves the inflammatory processes underlying the most common rhinologic conditions. The work details the pathophysiology of chronic rhinosinusitis, differentiating between presentations with and without nasal polyps, and connects these conditions to broader issues such as allergic triggers and immune system dysregulation.

The narrative guides the reader through the diagnostic evaluation of a patient with nasal complaints. It outlines the key elements of the clinical history and the systematic findings of a anterior and posterior rhinoscopic examination. The book places significant emphasis on the role of nasal endoscopy, illustrating how this tool provides a magnified, direct view of the middle meatus and other critical areas for diagnosing polyps, purulent drainage, or structural abnormalities. Further sections are dedicated to the interpretation of computed tomography scans, which offer a detailed anatomic map of the sinuses and are indispensable for planning surgical intervention. The text also covers the assessment of nasal airflow and smell disorders, linking these functional tests to patient-reported quality of life.

A substantial portion of the text investigates both medical and surgical treatment strategies. It outlines stepped medical management, including the use of topical nasal corticosteroids, saline irrigations, and courses of antibiotics or oral steroids for acute exacerbations. When medical therapy fails, the focus shifts to functional endoscopic sinus surgery (FESS). The work meticulously describes the principles and techniques of FESS, explaining how the goal is to restore sinus ventilation and drainage by enlarging natural ostia while preserving normal mucosa. The book also covers procedures for addressing a deviated nasal septum, reducing enlarged turbinates, and managing epistaxis.
