摘要

Background: We examined 94 toenails exhibiting clinical signs of severe onychomycosis taking into account multiple contributing factors, not the least of which was Subungual Osteochondroma Deformans (SOD). We hypothesize that SOD plays a significant role in both the etiology and treatment of onychomycosis. Methods/Results: A retrospective post-treatment outcome analysis was performed comparing two groups of severely mycotic toenails. The first group of 25 fungal nails showed 54.31% improvement following treatment by both surgical nail avulsion and a 1064 YAG laser-based Nail Restoration algorithm. The second group of 69 fungal nails was not only treated using the same nail avulsion/laser-based algorithm but was also evaluated for SOD lesions which were surgically removed when present, resulting in 95.31% improvement. The overall incidence of SOD lesions in the second group of severely mycotic toenails was 73.91%. Conclusion: We submit that at 73.91% Subungual Osteochondroma Deformans has an under-reported and under-appreciated association with toenail fungus. Generally, we find that our success rates in treating severe toenail fungus using our laser-based Nail Restoration Protocols are much higher when SOD lesions are surgically removed.
