For 1 preoperative month, the control group received daily saline (1\u2005mL) through gavage, whereas drug-treated groups received montelukast (10\u2005mg\/kg\/day) or tranilast (50\u2005mg\/kg\/day). Prophylactic groups initiated drug administration preoperatively. Miniature implants were bilaterally placed dorsally, followed by 3 months of postoperative drug continuation. Histopathological evaluation assessed capsule thickness, macrophage infiltration, collagen density, and inflammatory response.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>At 90 days post surgery, all drug interventions significantly reduced capsular thickness compared with the control group (control: 232.4 \u00b1 43\u2005\u03bcm; post-montelukast: 137.5 \u00b1 24\u2005\u03bcm; pre-montelukast: 107.7 \u00b1 20\u2005\u03bcm; post-tranilast: 93.3 \u00b1 22\u2005\u03bcm; pre-tranilast: 70.2 \u00b1 11\u2005\u03bcm; P &amp;lt; .0001).
