Surgery involved use of the argon laser to cross\u2010hatch the posterior cushion to modify the curvature of the cartilage of the posterior cushion and to alter the spring of the cartilage to make it wider and larger, thereby alleviating the obstructive dysfunction of the tube. None of the patients had any concurrent disease or surgical procedure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were no surgical complications. Following CHT, subjective symptoms of an ear blockage improved in 23 of 25 (92%) patients. Posterior cushion curvature became softer and wider, and the valve appeared more open postoperatively on simple endoscopy (SE) and slow motion video endoscopic analysis (SMVEA). Mean pure\u2010tone average improved by 10\u00a0dB (30\u00a0dB preoperatively vs 20\u00a0dB postoperatively; <jats:italic>P<\/jats:italic> = 0.015). Abnormal tympanogram improved in 24 of 25 (96%) patients. Failure of the procedure correlated with severity of cartilage deformation and valve obstruction as measured by both SE and SMVEA. Mean follow\u2010up was 15\u00a0months (range 3\u201037\u00a0months).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Cross\u2010hatching technique for Eustachian tuboplasty appears to be a safe and useful technique for treatment of Eustachian tube dysfunction.<\/jats:p><\/jats:sec>","DOI":"10.1016\/j.otohns.2009.12.046","type":"journal-article","created":{"date-parts":[[2010,4,22]],"date-time":"2010-04-22T04:39:09Z","timestamp":1271911149000},"page":"688-693","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Cross\u2010hatching: A novel technique for Eustachian tuboplasty.
