OBJECTIVES: To report outcomes of surgery for severe @entity2167 with or without partial atretic plate ( @entity2786 ). DESIGN: Retrospective review. SUBJECTS: Thirteen @entity1 (18 ears) had surgery for severe @entity2167 with (n=10, 56%) or without @entity2786 (n=8, 44%). Indications included severe @entity850 with @entity393 , cerumen impactions, and/or canal @entity3540 . Mean age=7.8 years (range 0.4-19.9 years). Mean follow up=5.2 years (range 0.4-10.0 years). SETTING: Tertiary care @entity1 's hospital. INTERVENTIONS: Nineteen endaural canaloplasties were performed in 17 ears (2 revisions). There was one post-auricular approach. Fifteen tympanoplasties were performed in 13 ears (2 revisions). @entity2786 was reconstructed with drilling to enlarge the bony annulus and fascia grafting to enlarge the tympanic membrane in 10 (56%) ears. OUTCOME MEASURES: Patency of EACs; otologic findings; pure tone averages (PTA); complications. RESULTS: All (100%) EACs had improved patency (>or=4mm). Findings included canal @entity3540 (2/18, 11%), @entity2170 (4/18, 22%), stapes abnormality (2/18, 11%), and incudostapedial discontinuity from @entity3540 (1/18, 6%). Mean preoperative PTA=38.7 dB HL (range 60-20 dB HL). Mean post-operative PTA=23.6 dB HL (range 50-6.7 dB HL). Audiologic results were significantly better for cases without @entity2786 (p<.01) and without @entity2170 (p<.01). There were seven minor and no major complications. CONCLUSIONS: Endaural canaloplasty is safe and effective for providing patent EACs and hearing improvement for severe @entity2167 . However, since hearing outcomes were worse for cases with @entity2786 and @entity2170 , alternatives such as hearing aids or BAHA may be considered.
