Reperforation occurred in 2 patients. The mean preoperative air-bone gap (ABG; 28.61 \u00b1 3.14 dB) was significantly greater than the mean postoperative ABG (12.15 \u00b1 3.98 dB; P &lt; .05) at 6 months; however, there was no statistically significant difference between the post-6 months and post-24 months with regard to ABG values ( P = .871), ABG gain ( P = 0.648), or functional success rate ( P = .472). No significant graft blunting or atelectasis was noted during follow-up. The free perichondrium became fully integrated with the skin of the external auditory canal; the perichondrium could not be clearly distinguished endoscopically 4 to 8 weeks postoperatively. Computed tomography revealed well-pneumatized middle ear and mastoid cavity at postoperative 24 months.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Endoscopic cartilage graft myringoplasty without tympanomeatal flap elevation reliably repairs posterior marginal perforations.
