Endoscopic Over Under Cartilage Tympanoplasty Is Not Inferior to Underlay Cartilage Tympanoplasty.

Evaluate whether elevating the tympanic membrane from the malleus during endoscopic tympanoplasty may negatively affect postoperative hearing outcomes or perforation rates by comparing 2 similar endoscopic tympanoplasty techniques. Retrospective cohort. Tertiary care center. Endoscopic over-under cartilage tympanoplasties age and gender matched to endoscopic underlay cartilage tympanoplasties between January 2015 and January 2019. Exclusion criteria included preoperative or intraoperative cholesteatoma, performance of mastoidectomy or ossicular chain reconstruction, and lack of postoperative audiogram. Endoscopic cartilage tympanoplasty via over-under or underlay technique. Pre- and postoperative pure-tone average and word recognition score, graft success. A total of 52 patients were evaluated: 26 endoscopic over-under cartilage tympanoplasties were matched to endoscopic underlay cartilage tympanoplasties. Both groups demonstrated a statistically significant improvement in air conduction hearing (9 dB [ Endoscopic over-under cartilage tympanoplasty effectively closes tympanic membrane perforations and improves hearing, without greater risk than underlay tympanoplasty. Elevating the tympanic membrane from the malleus does not confer worsen hearing outcomes.
