As Chief Resident and Assistant Chief of Service at Johns Hopkins Hospital over three decades ago, Dr. Nathan Nachlas experienced the advent of minimally invasive sinus surgery. He and his team have continued to pioneer medical advancements from the renowned Nose & Sinus Institute of Boca Raton, which he established in 1987. “Excellence is our passion, and that has inspired us to create a team of the best educated and trained specialists in our field,” says Nachlas.

The Institute led the specialty in the development of computer-guided sinus surgery, was the first in the United States to initiate computer-guided balloon sinuplasty, was the first in the country to insert a Genio® implant to treat obstructive sleep apnea, and was the first in the country to perform non- and minimally invasive treatments for nasal obstruction. These innovations serve Nachlas’ broader goal of offering a one- stop shop for both interior nasal issues and exterior aesthetic needs.

“We’re unique in that we specialize in the inside and outside of the nose,” partner Dr. Melyssa Hancock says. “What that means is there are doctors that go through an ENT residency and will fix breathing or sinus issues, and other doctors that do plastic surgery training and perform rhinoplasties and facelift surgery. We integrate these two fields. “

Even during the pandemic, patients at the Nose & Sinus Institute can breathe easily. NSIBR has plasma coil activated air filters throughout the entire office with documented eradication of 99.9 percent of airborne bacteria and viruses, and the staff has pioneered the use of molecular iodine for their procedures, which has been shown to have a 99.9 percent kill rate of the COVID-19 virus. “This is all in addition to strict PPE and masks and hand-washing and social distancing,” Hancock says. “Once inside our office, it’s a fortress. That has given great reassurance to our patients.”
