Patients underwent endoscopic transnasal\/transoral reconstruction of the obliterated ET using transtympanic illuminated guidewire guidance. A temporary stent (angiocatheter filled with bonewax) was placed to maintain patency while healing. In four cases an additional steroid\u2010eluting propel stent was placed in the ET orifice. Main outcome measures were otomicroscopy results, absence of middle ear effusion, and nasopharyngoscopy showing patency of the ET orifice.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Nine ETs (seven patients), ages 17\u201368\u2009years (mean 37.9) underwent ET reconstruction. Follow\u2010up ranged from 4 to 56\u2009months (mean 30.9\u2009months). 89% of operated ears had no effusion at last follow\u2010up. Two patients (three Eustachian tubes) underwent successful reoperation. There were no complications directly related to the procedure. Etiologies of obliteration included scarring after sinus surgery, obstruction after maxillo\u2010mandibular advancement surgery (two patients), bullous pemphigus, gunshot trauma, and previous patulous obliteration (two patients).<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Complete occlusion of the cartilaginous ET can be associated with intractable mucoid effusion; endoscopic examination should be considered in such cases. In this pilot study, ET reconstruction was found to be a safe and possibly effective procedure in patients with total obliteration of the ET from various etiologies. Larger studies with long term follow up are indicated.<\/jats:p>\n <\/jats:sec>\n \n Level of Evidence<\/jats:title>\n \n 4\n Laryngoscope<\/jats:italic>\n , 133:1970\u20131975, 2023\n <\/jats:p>\n
