Natural Sinus Rinse

Introducing SinusReLeaf Natural Sinus Rinse! A New Innovative Natural Sinus Rinse Formulation created by Dr. Yu-Syken inspired by her own struggle with Sinus Disease, now available to patients on the OCEANN ENT Home Page. SinusReLeaf is a revolutionary natural, herbal, hemp-based sinus solution for use as a Sinus Rinse (compatible with any over-the-counter sinus rinse bottle or mechanical irrigation machine). Not only does it help maintain appropriate nasal hygiene, but it also effectively reduces and alleviates inflammation associated with allergies, the common cold or flu, as well as bacterial or fungal infections of the sinuses and nose.
Irrigating out the nose and sinus cavities with SinusReLeaf Natural Sinus Rinse is similar to brushing our teeth to prevent cavities, and just like how we wash our hands to prevent the spread of germs...
Plus, enjoy $10 off First Purchase with RELEAF10 promotion to kickstart your journey to sinus relief!
Stop Medicating. Rinse-Breathe-Repeat!

Ear, Nose, Throat ENT


Sinus Specialists located in Huntington Beach, CA & Serving Patients in Southern California

Here at OCEANN ENT we offer comprehensive services for Ear, Nose, and Throat conditions with a Sub-Specialty Focus in Rhinologic conditions, especially those requiring extensive expertise in Sinus Procedures and Surgeries. Patients can count on personalized and compassionate care whether they have a sinus infection, ongoing allergies, Eustachian tube dysfunction, ear infection, throat disorders, or any other ENT problem. Evaluation begins at the initial phone call where our highly trained staff can assess patients’ current situation and schedule them with the most effective provider to best manage their presenting symptoms. The Sinus Surgeon, Dr. Kathy Yu-Syken, has personally trained her PAs (John Vincent Enverga, PA-C and Stephanie Cho, PA-C), who will be evaluating, diagnosing, and treating patients starting at their initial visit in order to most efficiently coordinate patient care. Although Dr. Yu-Syken will mostly be performing In-Office Sinus, Nasal, and Eustachian Tube Procedures due to the high volume of demand for her surgical proficiency, she will also still be available for more complex cases for consult, and to directly assess cases which may benefit from Sinus Procedures.
Although Dr. Yu-Syken always begins with the most conservative treatment that's best for each patient's needs, she specializes in Minimally Invasive and CT-guided Sinus Procedures such as In-Office Balloon Sinuplasty that are effective, minimize the need for mucosal incisions in some cases and limits the amount of sinus and nasal tissue removed, and produce long-lasting relief from conditions such as chronic sinusitis.
