This study aimed to evaluate the agreement between palpation and high-frequency ultrasound (USG) for assessing tunnel lengths in HS patients. Methods: This prospective study included patients who underwent the surgical excision of tunnels between May 2024 and July 2024 at a referral dermatology clinic. Tunnel lengths were measured preoperatively using palpation and USG. Clinical and demographic data, including lesion localization and disease severity, were prospectively recorded and analyzed. Results: This study analyzed 121 lesions from patients undergoing surgical excision for HS. Tunnel lengths measured by palpation had a median of 30 mm [IQR 18\u201340], while USG measurements had a median of 36 mm [IQR 24\u201351.5], with USG identifying tunnels 10.3 mm longer on average (95% CI: 8.2\u201312.3). Axillary lesions were most frequent (53.7%), followed by inguinal (32.2%) and sacral regions (6.6%). Most lesions were classified as Hurley stage 2 (59.5%) and stage 3 (37.2%), with a median IHS4 score of 8 [IQR 7\u201311]. Conclusions: High-frequency USG offers greater precision than palpation in measuring tunnel lengths, indicating its potential to enhance disease assessments in HS.<\/jats:p>","DOI":"10.3390\/diagnostics15111442","type":"journal-article","created":{"date-parts":[[2025,6,5]],"date-time":"2025-06-05T11:04:06Z","timestamp":1749121446000},"page":"1442","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Preoperative Tunnel Measurement in Hidradenitis Suppurativa: Comparison of Palpation and Ultrasound"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9177-2273","authenticated-orcid":false,"given":"Asl\u0131","family":"Tatl\u0131parmak","sequence":"first","affiliation":[{"name":"Department of Dermatology, \u00dcsk\u00fcdar University, 34768 \u0130stanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-6130-3311","authenticated-orcid":false,"given":"Murat","family":"Do\u011fan","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Ba\u015fak\u015fehir \u00c7am and Sakura City Hospital, Health Sciences University, 34480 \u0130stanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zafer","family":"T\u00fcrko\u011flu","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Ba\u015fak\u015fehir \u00c7am and Sakura City Hospital, Health Sciences University, 34480 \u0130stanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"18","DOI":"10.1038\/s41572-020-0149-1","article-title":"Hidradenitis Suppurativa","volume":"6","author":"Sabat","year":"2020","journal-title":"Nat.
