The control group was treated with glucocorticoids by nasal spray for 1\u00a0year according to the conventional method, while the experimental group received topical nasal glucocorticoids using the 3D-printed track-guided precise sinus drug delivery device for 1 year. Scores on the Sino-Nasal Outcome Test (SNOT-22) scale and the Lund-Kennedy nasal endoscopic scale during reexamination at 1\u00a0month, 3\u00a0months, 6\u00a0months, and 1\u00a0year after the operation were used as the basis for evaluation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The follow-up duration was 12\u00a0months or more following endoscopic sinus surgery (ESS) with neosinus cavity formation.
