Our Vision & Mission

The Texas Sinus, Allergy, Snoring and Sleep Institute (TSASSI)  is founded on a vision of excellence for advanced and thoughtful solutions for sinus, allergy, snoring and obstructive sleep apnea relief.

Dr. Khetarpal is the founder of TSASSI and is DOUBLY Board-Certified in Ear, Nose and Throat-Head, Neck and Facial Plastic Surgery as well as in Sleep Medicine.

Chronic rhinosinusitis affects about 30-37 million Americans, with an equal or somewhat higher prevalence of Allergic Rhinitis and Snoring and Sleep Apnea in the population. If you or your loved one has been suffering from sinus headaches, facial pain, persistent or repeat sinus infections, smell and taste problems, fatigue, body pain and a reduced sex life due to sinus problems, or have annoying snoring and sleep apnea, we have the solutions to improve and even cure some or all of these problems. Dr Khetarpal is amongst the first few surgeons in the country to offer Image Guided In Office Comprehensive Sinus Surgery and PIVA™ Balloon Sinuplasty. He is currently conducting research in sinusitis and allergic rhinitis with the approval of the Western Institutional Review Board that oversees this research. Because of his interest in Sleep disorders, particularly snoring and Obstructive Sleep Apnea, Dr Khetarpal, obtained Board Certification in Sleep Medicine so that he could provide a consistently high quality of care for these patients.

Dr Khetarpal has recently presented 5 research papers on Recurrent Acute Rhinosinusitis at the International Meeting of Rhinology in Chicago, June 2019. There are very few Sinus specialists in private practice conducting sinus or allergy research in the US. He is one of those few.
