    2. Overview Focus on Nasal Obstruction Anatomy Histology and Physiology Evaluation of Nasal Obstruction Turbinate Disorders Medical Management Surgical Management

    3. Anatomy Inferior Turbinate: An inferior infolding of the lateral nasal wall. 60 mm in anterior to posterior direction. Forms an important component of the nasal valve. Derived from the maxilloturbinal ridge.

    4. Anatomy Middle Turbinate Lies medial to the anterior ethmoid air cells, the maxillary sinus ostium, the nasofrontal duct, and the uncinate process. Length of 40 mm and mean height of 14.5 mm anteriorly and 7 mm posteriorly. Develops from the second ethmoturbinal.

    5. Anatomy Superior Turbinate Meatus drains the posterior ethmoid air cells.

    6. Anatomy Nasal Valve External Nasal Valve Boundaries include: lower lateral cartilages Soft tissue alae Membranous septum Sill of the nostril Can be site of obstruction (e.g. s/p rhinoplasty)

    7. Anatomy Internal Nasal Valve Boundaries include: Septum Upper lateral cartilages Anterior end of inf. Turbinate 1.3cm from nares Accounts for 50% of airway resistance Inferior turbinate can affect this area greatly

    8. Histology Three layers of Turbinates Medial thin mucosa Bone Lateral thick mucosa
