The aim of this study was to compare the therapeutic efficacy of local hyperbaric oxygen therapy with local ozone therapy in the treatment of venous leg ulcers. Materials: this study included 114 patients; 60 males (52.63%) and 54 females (47.36%) of ages ranging between 39 and 88 years (mean age: 68.9 \u00b1 9.8 years) with venous leg ulcers, who underwent topical hyperbaric oxygen therapy (group I) and local ozone therapy (group II). In each of the study groups, the patients underwent 30 therapeutic procedures lasting 30 min each. The progress in wound healing was evaluated by computerized planimetry, and the intensity of pain was assessed with the use of the Visual Analogue Scale (VAS). Results: in both groups of treated patients, a statistically significant (p = 0.000001) reduction in the area of treated ulcers was achieved. In group I, the wound area decreased by an average of 69.67 \u00b1 22.52%, from 7.55 \u00b1 2.99 cm2 to 2.78 \u00b1 2.43 cm2, and in group II, by an average of 41.33 \u00b1 21.31%, from 7.36 \u00b1 2.82 cm2 to 4.62 \u00b1 2.76 cm2. In both groups of patients, a statistically significant (p = 0.000001) reduction in the intensity of pain ailments was observed: in group I, by an average of 0.55 \u00b1 0.54 points, and in group II, by an average of 2.33 \u00b1 0.82 points on the VAS scale. Conclusions: local hyperbaric oxygen therapy and local ozone therapy cause a statistically significant reduction in the surface area of venous leg ulcers as well as in the intensity of pain. Better results were observed after the application of local hyperbaric oxygen therapy procedures.<\/jats:p>","DOI":"10.3390\/ijerph20031967","type":"journal-article","created":{"date-parts":[[2023,1,23]],"date-time":"2023-01-23T02:01:02Z","timestamp":1674439262000},"page":"1967","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Topical Hyperbaric Oxygen Therapy Versus Local Ozone Therapy in Healing of Venous Leg Ulcers"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6181-337X","authenticated-orcid":false,"given":"Jaros\u0142aw","family":"Pasek","sequence":"first","affiliation":[{"name":"Faculty of Health Sciences, Jan D\u0142ugosz University in Cz\u0119stochowa, 13\/15 Armii Krajowej St., 42-200 Cz\u0119stochowa, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4983-8018","authenticated-orcid":false,"given":"Sebastian","family":"Szajkowski","sequence":"additional","affiliation":[{"name":"Faculty of Medical Sciences, Medical University of Mazovia in Warsaw, 8 Rydygiera St., 01-793 Warszawa, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7574-4456","authenticated-orcid":false,"given":"Valter","family":"Travagli","sequence":"additional","affiliation":[{"name":"Department of Biotechnology, Chemistry and Pharmacy, Viale Aldo Moro 2, 53100 Siena, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2210-8744","authenticated-orcid":false,"given":"Grzegorz","family":"Cie\u015blar","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Angiology and Physical Medicine, Faculty of Medical Sciences in Zabrze, Medical University of Silesia in Katowice, 15 Stefana Batorego St., 41-902 Bytom, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8","DOI":"10.1016\/j.annepidem.2018.10.005","article-title":"Prevalence of chronic wounds in the general population: Systematic review and meta-analysis of observational studies","volume":"29","author":"Martinengo","year":"2019","journal-title":"Ann.
