What Is an ENT (Ear, Nose, and Throat) Doctor?
──

An ear, nose, and throat specialist is much as the title implies. Such a specialist treats the many conditions that affect the connected structures and passages in the ears, nose, and throat. In Dr. Killian’s case, however, his training included an additional year in Rhinology and Anterior Skull Base Surgery to provide definitive expertise in performing complex and minimally invasive endoscopic nasal and sinus surgery, as well as more complicated conditions such as cerebrospinal fluid (CSF) leaks and nasal and sinus tumor removal without external incisions.

Treasure Valley Nasal and Sinus Center focuses primarily on the following:

While Dr. Killian is a regionally recognized sinus surgeon, surgery is not the first line of treatment for most common ENT diseases. Dr. Killian listens carefully and considers patients’ wishes in determining effective, minimally invasive treatment plans.

When non-surgical treatment has been ineffective, Dr. Peter Killian is best qualified to carefully consider surgical options for your ear, nose, or throat condition. As a rhinologist and otolaryngologist, his use of endoscopic sinus surgery minimizes recovery time and allows continued medical therapy to be much more effective.

Dr. Killian & Crew, 
One year ago on Halloween, Sterling had his adenoids and turbinates removed. Since then, he has noticed a great difference in how he sleeps and feels and he has grown exponentially. I just want to thank you for your generosity and kindness. You all took wonderful care of my son and we appreciate you and what you did for him. Thank you so very much!

Dr. Killian, 
I wanted to write and personally thank you for all the care you have given my daughter Leah. The respect you have shown for our religious convictions has been more appreciated than you know. This has been a difficult period in our life but being able to put her in the care of such professional and caring hands has helped greatly. Please convey our appreciation to your family and staff as well.

It means so much that you took the time to listen and understand and comfort my thoughts and emotions. You have gone above and beyond what you ever had to do out of the goodness of your heart. I am forever grateful. Thank you.
