Otolaryngology | Rhinology

    Overview

    If nasal congestion, chronic sinus disease or more complex problems affecting the skull base are impacting your life, SIU Medicine is here to help. Our fellowship‑trained rhinologists use evidence-based approaches to treat everything from routine sinus disease to tumors or brain fluid leaks—all within a patient-centered, collaborative environment.

    What is Rhinology?

    Rhinology is a subspecialty of otolaryngology (ENT) focused on the care of the nose, sinuses and skull base. We diagnose and treat diseases that affect breathing, smell, sinus health and more.

    What to Expect: Our Approach

    1. Comprehensive Evaluation
      We begin with nasal endoscopy to directly visualize your anatomy and symptoms in real time. Advanced CT and MRI imaging help assess disease spread and guide planning.
    2. Personalized Treatment Plan
      Whether steps begin with medications or proceed to surgery, we design your care based on your goals, health and unique anatomy.
    3. Advanced Surgical Precision
      For patients needing surgery, our team offers minimally invasive, endoscopic options—often with image-guided systems and without external incisions—to reduce recovery time and minimize complications.
    4. Post‑Procedural Support
      We provide thorough after‑care including saline irrigation and in‑office debridement to promote healing, prevent scarring and optimize long‑term results.
