The purposes of this exhibit are to: 1. Describe the normal anatomy of the paranasal sinuses and their relationship with normal development and growth. 2. List common and uncommon anatomic variants. 3. Review the clinical-surgical classifications commonly used during the evaluation of patients with suspected nasal-paranasal sinus disease.  

1. Normal development of paranasal sinuses (PS). 2. Normal anatomy of nasal cavity and PS and their implication in disease and pre-surgical evaluation. Normal measurements of PS, choanas, vomer, mucosal thickness 3. Anatomic variants of septum, nasal turbinates, air cells, drainage pathway, accessory ostia, ostiomeatal complex, and common and uncommon areas of pneumatization 4. Radiologic-surgical commonly used classifications: Mladina’s & Kuhn´s classifications, Keros´index and Cottle´s area

1. Paranasal sinuses and nasal cavity anatomy is complex, and include several and common anatomic variants. A complete knowledge and full understanding of them allows a correct interpretation of the scan. In this exhibit we present a different approach (mostly based in VR reformations) to understand paranasal sinuses anatomy. 2. A common nomenclature of this complex anatomy (including several classfications) is  helpful for a better approach of the disease, surgical planning and treatment.
