Dr. Michael Purkey

California Sinus Centers welcomes Dr. Michael Purkey

California Sinus Centers is pleased to welcome a new provider to our team. Dr. Michael Purkey joins us from the University of Pennsylvania, where he has been in residency for the past five years. Dr Purkey was inspired to pursue Rhinology during medical school after sitting in on a surgery with Penn professor and surgeon Dr. Alex Chiu. Dr. Chiu, who trained at California Sinus Centers, showed that a combination of surgical skill and applied technology can yield advanced levels of care to patients suffering from sinus disease. Dr. Purkey states that “it was from that moment that I chose Rhinology as a sub-specialty.”

While in his residency Dr. Purkey has collaborated with other doctors in research into the genetic causes of sinusitis. Dr. Purkey will be seeing patients in the Atherton and Walnut Creek offices and will operate out of the surgery centers associated with those locations.

Atherton California Sinus Centers 5th Anniversary Celebrated

April 1st, 2014 marked the 5 year Anniversary of California Sinus Centers’ opening its doors in Atherton. We marked the occasion with a celebration that included Jamaican food, a steel drummer, and a relaxed attitude. Bay Area referring doctors, their staff and friends were invited to attend. While (much needed) rain moved the group indoors, everyone still had a great time visiting and catching up. We missed those who could not attend, but are very grateful for your support. We look forward to hosting you at our 10th Anniversary!

Nosey News: Polyp Vac approved for use in the US

PolypVac Sinus Polyp RemovalIt is with great excitement that we can announce the FDA’s approval of the newest tool in the fight against sinus disease here in the US: the PolypVac.

The PolypVac was developed by doctors from Cal Sinus and other institutions in conjunction with Redwood City based Laurimed, LLC. The purpose of its development was to address the need for a tool that can remove certain types of sinus polyps in an office environment. The tool may allow a skilled Rhinologist to address a patient’s polyps in a properly equipped office exam room instead of an ambulatory surgery center. Having the polypvac in their toolbag may allow a surgeon to bring treatment to the patient. Not only may this potentially save patients the time they might have spent traveling to an ambulatory surgery center, it also saves them the associated medical costs and general anesthesia.

The PolypVac has been in use in Canada for over a year but recently gained FDA approval in the US. Laurimed is in the process of distributing the device to doctors for its use. California Sinus Centers has been (successfully) using the tool since February of this year (2014) to treat patients affected with certain types of polyps. Patients report that their symptoms have diminished greatly and they can return to going about their daily lives. The first surgeon in the US to use the device was Dr. David W. Clark, a Cal Sinus trained surgeon now practicing in Temple, Tx.
