Effect of Multi-Wavelength Photobiomodulation (PHOVIA) on Postoperative Healing and Complication Rates Following Total Ear Canal Ablation with Bulla Osteotomy in Dogs

The University of Florida College of Veterinary Medicine is currently recruiting dogs that have received a total ear canal ablation with Bulla Osteotomy.

Enrollment Status: Enrolling

Inclusion Criteria: Dogs of any breed or sex diagnosed with end-stage ear infections (otitis externa or media) that require a total ear canal ablation and bulla osteotomy (TECA-BO) will be eligible for enrollment. 

Study Procedures: All dogs will receive the standard of care for TECA-BO surgery and routine postoperative recovery. During surgery, after the incision is closed, one half of the incision will be randomly assigned to receive PHOVIA treatment. A proprietary gel will be applied to that half of the incision, then illuminated with a special LED light for two 2-minute applications (approximately 4 minutes total). A sterile barrier will be placed at the incision midpoint to prevent light exposure to the untreated side.

After surgery, two postoperative hospital visits are required. The first visit will take place 5–9 days after surgery. During this visit, a second PHOVIA treatment will be performed on the incision. If discharge is present at the incision site, a small sample may be collected for cytologic evaluation. The second postoperative visit will occur approximately 14–18 days after surgery for incision assessment and routine suture removal.

To monitor healing, infrared thermography (IRT) will be performed after surgery at specific time points. This is a non-invasive imaging method that takes temperature-based pictures of the incision to evaluate blood flow. It does not require sedation, needles, or contrast agents, and poses no risk or discomfort to your dog. 

Cost: The study will cover the cost of the PHOVIA light therapy and cytology but there is otherwise no financial incentive for your dog’s participation. 

Background: The purpose of this study is to test a new light-based therapy called PHOVIA, which combines a gel with a gentle LED light to support healing at the incision. This treatment may reduce bacteria, improve blood flow, and help cells repair themselves. By studying this approach, we hope to find safer and more effective ways to lower the risk of incision site infections and improve recovery for dogs after surgery.
