Boomerang-Shaped Cartilage Graft in Endoscopic Tympanoplasty
Sponsor: Assiut University
Summary
This study evaluates the anatomical and functional outcomes of using a boomerang-shaped chondroperichondrial graft in endoscopic Type I tympanoplasty for repairing anterior or subtotal tympanic membrane perforations. Anterior and subtotal eardrum perforations represent challenging surgical scenarios due to limited visualization, lack of anterior graft support, and higher risks of graft retraction, medialization, or residual perforation. The boomerang-shaped cartilage and perichondrium graft provides a sturdy cartilage framework along the anterior border to secure structural support, while maintaining a thin perichondrial layer over the functional vibratory area to facilitate acoustic transmission. All enrolled participants undergo endoscopic Type I tympanoplasty using this autologous grafting technique. Follow-up assessments are conducted at 1, 3, and 6 months after surgery to determine successful graft uptake, evaluate hearing improvement (via pure-tone audiometry and air-bone gap closure), and monitor for complications such as blunting, retraction, lateralization, or infection.

Endoscopic Type I Tympanoplasty with Boomerang-Shaped Chondroperichondrial Graft
Endoscopic Type I tympanoplasty performed using a rigid endoscope to repair anterior or subtotal tympanic membrane perforations. The autologous boomerang-shaped chondroperichondrial graft provides a stable anterior cartilage framework to prevent graft medialization, retraction, and residual perforation, while preserving a thin perichondrial layer over the functional vibratory surface to optimize acoustic transfer. Anatomical graft uptake and complication rates are monitored at 1, 3, and 6 months postoperatively, and functional hearing outcomes (pure-tone audiometry thresholds and air-bone gap closure) are measured at 6 months.
