Their unique approach to surgery, combined experience, and constant innovation has allowed them to create many new and innovative surgical procedures that have bridged large gaps in current surgical techniques including transoral salivary gland surgery, reconstructive flaps for facial defects, and expanded the scope of sialendoscopy procedures to remove stones traditionally thought too large to be removed via traditional endoscopic techniques. Dr. Osborne and Dr. Hamilton are also considered master diagnosticians often serving as tertiary consultants, diagnosing illusive previously undiagnosable conditions.

Featured Patient Cases

large parotid tumor surgery

My benign parotid gland tumor was a 31 year growth until my daughter found OHNI’s incredibly informative website, miraculously, it seemed to me. For I had years ago given up hope of finding a doctor to safely and without facial nerve damage, remove my increasingly grotesque looking and physically debilitating tumor.

Remarkably, after an 11 hour procedure to remove a 7 pound approximate weight tumor, I experienced no pain whatsoever. That first night, to quell the worry of family who insisted I’d need it, I reluctantly took one prescribed painkiller. That very next day we had lunch out after a tour of the market.

I felt great! In the following days I had bruising and swelling of my face that subsided within the week, but no discomfort. On the third day post surgery, following the removal of the drain, the entire staff gathered in that little room for a look at the new me….

Featured Patient Cases

parotid tumor surgery

Dr. Osborne and Dr. Hamilton were truly an answer to my prayers. I have seen many surgeons over the last 8 years. Even though a parotid tumor isn’t the end of the world, the standard surgery seemed to be close. I had talked to surgeons and patients alike. None of whom gave me a very promising outcome. I searched online and found the website. I looked several times before I finally set up a consult.


Had I known how wonderful these two surgeons were, I would have been here sooner. They made no promises, but they let me know they would do everything humanly possible… And they did. My surgery was better than I could have ever dreamed. I’m still having a hard time realizing the smile on my face is real. They may have only done what was humanly possible, but I believe God blessed them with skills beyond most men. They also have a wonderful energy that is carried throughout the entire office staff. Thank you.

  • Your Parotid Surgery

    Having parotid surgery and finding the right surgeon to perform your procedure can be stressful. From the worries of possible tumor recurrence, to the risk of permanent facial paralysis and deforming facial scars, it is always in your best interest to get a second opinion. Remember, most physicians only perform 1-4 of these procedures a year. At the Institute, we often perform as many procedures in one week. There is no substitute for focus and experience. Dr. Osborne and Dr. Hamilton work together to provide a sound tumor surgery combined with a cosmetically appealing outcome. We understand that it is often inconvenient, time-consuming and expensive for patients to fly to our Los Angeles office for a consultation, then fly back again a few weeks later for surgery. We have designed a program to facilitate your experience that will allow you to determine the best options available to you from the comfort of your home.
