• If Eos <5/HPF: Usual post-op meds, Intranasal steroid spray, NS
• If Eos Midrange/HPF: ISS, NS, Short oral steroid taper, budesonide irrigations, LT receptor antagonists budesonide in 3 oz NS, 1.5 oz irrigation each nasal cavity bid
• If Eos >20/HPF, ISS, budesonide irrigations, month long oral steroid taper, LT receptor antagonists budesonide in 3 oz NS, 1.5 oz irrigation each nasal cavity bid - consider anti-Lipo-oxygenase medications if failure

• Endoscopy
• Maximize medical therapy
• CT evaluation
• Game plan
• Image guidance

• Surgical techniques
• Uncinectomy
• Incorporate natural max ostium into
antrostomy
• Enter bulla inferiorly and medially
• Do not work in a hole
• Identify Lamina
• Respect the vertical plane of the MT
• Preserve horizontal basal lamella
• Do not open MMA flash to the posterior
maxillary sinus wall

-Posterior - sphenopalatine
-Inferior - SAFER
