Conditions We Treat

Patients come to the Los Angeles Sinus Institute for a wide range of nasal and sinus conditions, including:


  • Sinusitis: Inflammation of the sinuses that may be acute or chronic and may or may not involve infection.
  • Nasal Allergies: Chronic allergy symptoms affecting the nose and sinuses, including congestion and post-nasal drip.
  • Nasal Polyps: Soft, noncancerous growths in the nasal passages that can block airflow and reduce sense of smell.
  • Deviated Septum: A shifted nasal septum that can obstruct breathing and contribute to snoring or sleep disruption.
  • Turbinate Hypertrophy: Swelling of the nasal turbinates that narrows the airway and causes chronic congestion.
  • Nasal Congestion and Sinus Pressure: Persistent symptoms that may point to an underlying structural or inflammatory cause.

ENT Treatments and Procedures

Dr. Zadeh offers a range of treatment options, from conservative medical management to advanced surgical procedures, including:


  • Balloon Sinuplasty: A minimally invasive procedure that widens the sinus passageways using a small balloon catheter, restoring normal drainage while preserving healthy tissue.
  • Sinus Surgery: Endoscopic surgery to treat chronic sinus infections and structural blockages when other treatments have not provided relief.
  • Septoplasty: Surgical correction of a deviated septum to improve nasal airflow.
  • Turbinate Reduction: A procedure to reduce swollen turbinate tissue and open the nasal airway.
  • Clarifix: A cryotherapy treatment for chronic runny nose and nasal congestion.
