Stapedectomy: gelfoam compared with tissue grafts.

J L Sheehy, J H Perkins

    The Laryngoscope
    |March 1, 1976
    PubMed
    Summary

    Tissue grafts are superior to gelfoam for oval window covering in stapedectomy, reducing complications like vertigo and hearing loss. This study compared gelfoam, fat, and fascia grafts in 573 primary cases.

    Area of Science:

    • Otolaryngology
    • Surgical Innovation
    • Biomaterials in Otology

    Background:

    • The prefabricated wire loop-gel foam pad technique for stapedectomy presents common failure modes.
    • These failures include loop displacement, membrane formation, and window fibrosis.
    • Some surgeons have switched from gelfoam to tissue grafts to mitigate these issues.

    Purpose of the Study:

    • To compare the efficacy and complication rates of gelfoam versus tissue grafts (fat and fascia) as oval window coverings in primary stapedectomy cases.
    • To evaluate the long-term outcomes and patient safety associated with different graft materials.

    Main Methods:

    • A comparative study involving 573 primary stapedectomy cases.
    • Gelfoam, fat grafts, and fascia grafts were used as oval window coverings.
    • Outcomes including postoperative vertigo, hearing impairment, fistulas, and hearing regression were assessed.

    Main Results:

    • Tissue grafts demonstrated a lower incidence of postoperative vertigo compared to gelfoam.
    • The use of tissue grafts resulted in less temporary and permanent sensorineural hearing impairment.
    • Tissue grafts also showed reduced rates of fistulas and long-term hearing regression.

    Conclusions:

    • Tissue grafts are preferable to gelfoam for oval window coverage in stapedectomy.
    • The findings support the use of tissue grafts for improved patient outcomes and reduced complications.
    • This study highlights the advantages of tissue grafts in otologic surgery.
