Objective: Determine the safety and efficacy of balloon dilation of the Eustachian tube (ET) in pediatric patients. Study Design: Retrospective matched cohort study. Setting: Tertiary medical center. Patients: Pediatric patients (<18 yr) with persistent (>1.5 yr) chronic Eustachian tube dysfunction (ETD) with previous tympanostomy tube (TT) insertion versus matched controls. Intervention(s): Balloon dilation of the cartilaginous ET (BDET) was performed using concomitant myringotomy with/without tube placement and adjunctive procedures if indicated versus controls (TT). Main Outcome Measure(s): Otitis media with effusion (OME)/retraction with need for additional tube, tympanogram, audiogram, otomicroscopy, ET mucosal inflammation/opening score, and Valsalva maneuver. Results: Forty six ETs (26 patients), ages 7 to 17 years (mean 12.5) underwent BDET. Mean follow-up was 2.3 years (standard deviation [SD], 1.1; range, 6 mo–5 yr). Significant improvements were observed for all measures. Tympanic membranes were healthy in 9% preoperatively, 38% at 6 months, 55% at 12 months, and 93% at 36 months postoperatively. Tympanograms improved to type A in 50% at 6 months, 59% at 12 months, and 85% at 36 months. Mean scores of mucosal inflammation declined from 3.2 (±0.6) preoperatively to 2.5 (±0.7) at 6 months and 1.7 (±0.6) at 36 months postoperatively. BDET had lower risk of failure versus TT insertion (adjusted hazard ratio [HR] 0.26; 95% confidence interval [CI]: 0.10, 0.70; p = 0.007). Probability of being failure free at 2 years was 87% (95% CI: 70, 94%) after BDET and 56% (95% CI: 40, 70%) after TT insertions. Conclusions: BDET is a safe and possibly effective procedure in selected pediatric patients with chronic ETD.
Objective: To investigate the safety and early efficacy of a procedure for reconstruction of the obliterated Eustachian tube (ET).Study Design: Retrospective case series. Methods: Patients with total obliteration of the cartilaginous ET, with intractable mucoid effusion causing repeated occlusion of tympanostomy tubes were included. 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-eluting 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.Results: Nine ETs (seven patients), ages 17-68 years (mean 37.9) underwent ET reconstruction. Follow-up ranged from 4 to 56 months (mean 30.9 months). 89% of operated ears had no effusion at last follow-up. 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-mandibular advancement surgery (two patients), bullous pemphigus, gunshot trauma, and previous patulous obliteration (two patients).Conclusions: 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.
