The aim of this study was to evaluate the outcomes of using a U-Linear split-thickness skin graft (U-Linear STSG), a novel modified graft placement technique for canaloplasty.  \nMaterials and Methods:  \nA retrospective cross-sectional study was conducted on patients who underwent canaloplasty between January 2013 and December 2023. The medical records of external auditory canal stenosis patients who underwent canaloplasty were reviewed. The data collected included patient demographics, surgical approaches, postoperative outcomes, and audiometric findings. The outcomes of reconstruction for ear canal stenosis using a U-Linear STSG were compared with those using a reconstructed local flap. Statistical analyses included chi-square tests for categorical data and independent t tests for continuous data.  \nResults:  \nThirty-six patients with external auditory canal stenosis underwent reconstruction; 17 patients underwent reconstruction with a U-Linear STSG, and 19 patients underwent reconstruction with a local flap. A review of the clinical outcomes revealed that postoperative restenosis was significantly less common in the U-Linear STSG group than in the local flap group (p \u003C 0.05) . In terms of audiometry, the postoperative air‒bone gap in the U-STSG group was slightly greater than that in the local group. No serious complications were observed in either group.  \nConclusion:  \nA U-Linear STSG can be simply and feasibly applied in reconstruction for ear canal stenosis, with no major complications.  \nKeywords: external auditory canal stenosis, canaloplasty, split thickness skin graft, audiometry  \nReceived date: 16 Apr 2025  \nAccepted date: 06 Oct 2025  \n*Please cite this article; Mahawerawat K, KasemsiriP, Chit-uea-ophat Ch.

Acquired external auditory canal stenosis can result from various factors that trigger inflammatory tissue responses, ultimately leading to narrowing of the external auditory canal.  \nThe incidence of acquired external auditory canal stenosis is approximately 0.6 per 100,000 individuals (1) .  \nThe causes of acquired external auditory canal stenosis include chronic otitis externa, dermatologic diseases, iatrogenesis (resulting from previous ear surgery or radiotherapy), trauma, and tumours (2) .  \nThe consequences of external auditory canal stenosis include hearing loss and the possible development of a cholesteatoma.  \nLavy and Fagan (3) reported conductive hearing loss in patients with an air‒bone gap of approximately 30–40 dB, along with a flat tympanogram and the absence of stapedial reflexes. Additionally, progressive hearing loss of 15 dB to 40 dB was observed over an 8-year period (4) .  \nBecker and Tos (1) reported that, in patients who develop a cholesteatoma, 9% ofcholesteatom","cbCaiprsKDoN3pqm","https://ap.wps.com/l/cbCaiprsKDoN3pqm","pdf",333987,"English","# Introduction\n## Materials and Methods\n## Results\n## Conclusion\n## Keywords","[{\"question\":\"What was the study aim regarding U-Linear STSG in canaloplasty?\",\"answer\":\"To evaluate the clinical outcomes of using a U-Linear split-thickness skin graft (U-Linear STSG) as a novel modified graft placement technique for canaloplasty.\"},{\"question\":\"How were the patients grouped for reconstruction in this study?\",\"answer\":\"Thirty-six patients were included, with 17 receiving reconstruction using U-Linear STSG and 19 receiving reconstruction using a reconstructed local flap.\"},{\"question\":\"What were the main postoperative findings comparing U-Linear STSG vs local flaps?\",\"answer\":\"Postoperative restenosis was significantly less common in the U-Linear STSG group (p \\u003c 0.05).
