Ear, Nose, & Throat
From persistent sinus problems and hearing concerns to thyroid conditions and complex head and neck disorders, Snoqualmie Valley Health provides specialized ear, nose and throat (ENT) care to help you breathe, hear, speak and feel better.
Also known as otolaryngology (pronounced “oh-toe-lair-in-GAWL-uh-jee”), ENT is a medical and surgical specialty focused on conditions affecting the ears, nose, sinuses, throat and other structures of the head and neck. ENT specialists treat conditions that can affect breathing, sleep, smell, swallowing, speaking, hearing, balance and thyroid and parathyroid health.
Our ENT specialist, Peiran Zhou, MD, offers both surgical and nonsurgical treatment options, working with you to understand your concerns and develop a personalized care plan.
We care for patients ages 3 and older. We also evaluate younger children experiencing recurrent middle ear infections to determine whether ear tube placement without general anesthesia may be appropriate.

Advanced Reconstructive Surgery
Our ENT surgeon performs transoral robotic surgery (TORS), a minimally invasive procedure that uses robotic-assisted instruments inserted through the mouth to access and remove tumors in the throat without external incisions.
Our team also offers free flap reconstruction, which uses tissue such as skin, muscle, or bone from another part of the body to reconstruct areas of the head and neck after tumor removal. This approach helps restore both form (appearance) and function (including swallowing and speaking).
When to See an Ear, Nose, & Throat Provider
When ear, nose or throat symptoms affect your daily life, specialized care can help. An ENT doctor diagnoses and treats concerns such as recurring sinus and ear infections, hearing changes, balance problems, and difficulties with voice or swallowing. If symptoms keep coming back or aren’t improving with treatment, an ENT can help identify the cause and recommend care tailored to your needs.
Talk with your primary care provider about whether a referral to an ENT is right for you.
