Purpose or Case Report: The human airway is fundamental to respiratory gas transmission and oxygen exchange. The pediatric upper airway is subject to a number of specific age and location related disease processes that can cause alarming morbidity and could be deadly by impairing normal air movement. In this exhibit, we guide the learner on a fantastic journey thorough the pediatric upper airway from nose to cords illustrated thorough neuroimages. Congenital and acquired anatomic and pathologic barriers to airflow will be reviewed.
Methods & Materials: CT, MRI, ultrasound and radiographic images with didactic value will be procured from the teaching file of a pediatric medical center in order to demonstrate anatomy and pathology of the pediatric upper airway.
Results: Specific entities illustrated and discussed as follows:

1. Sinuses
a. Congenital:
-variants
b. Acquired:
-Sinusitis and its complications
-Cystic fibrosis
-Polyposis
-Allergic fungal sinusitis
-Trauma/hemorrhage/fracture
-Pott's puffy tumor
-Granulomatosis with polyangitis
-Lymphoma

2. Nose and Nasopharynx
a. Congenital:
-Choanal atresia
-Piriform aperture stenosis
-Tumor (dermoid, nasopharyngeal angiofibroma, rhabdomyosarcoma)
-Encephalocele
b. Acquired:
-Penetrating trauma: palate
-Infection: adenoiditis
-Foreign bodies

3. Oral Cavity and Oropharynx:
a. Congenital:
-Congenital deformities: Pierre Robin sequence
-Ranula
-Teratoma
-Lymphangioma
-Thyroglossal duct cyst (TGDC)/lingual thyroid
b. Acquired:
-Trauma
-Tonsillitis/abscess/pharyngitis
-Epiglottitis

4. Hypopharynx/larynx:
a. Congenital:
-Hemangioma
-TGDC
-Dermoid
-Laryngomalacia
-Vocal cord paralysis
b. Acquired
-Retropharyngeal abscess
-Trauma with air leak
-Pertussis, Croup
Conclusions: A variety of diseases may affect the pediatric upper airway. Location and imaging characteristics are primary determinants of the differential diagnosis.
