Tympanoplasty using formaldehyde formed fascia grafts

Area of Science:

• Otolaryngology
• Surgical Innovation
• Regenerative Medicine

Background:

• Total tympanic membrane perforations present significant surgical challenges.
• Traditional methods often result in complications like anterior sulcus blunting and graft lateralization.
• Rodney Perkins introduced a novel technique using formaldehyde-treated temporalis fascia in 1975.

Purpose of the Study:

• To review the efficacy of formaldehyde-formed fascia (FFF) grafts for total tympanic membrane perforations.
• To evaluate outcomes in cases with and without concomitant middle ear ossicular reconstruction.
• To assess the impact of FFF grafts on postoperative complications and hearing improvement.

Main Methods:

• Review of 139 cases utilizing formaldehyde-treated temporalis fascia grafts.
• Grafts were shaped using a metal mold to mimic normal tympanic membrane anatomy.
• Analysis of postoperative nonperforation rates, graft stability, and audiological results.

Main Results:

• A high postoperative nonperforation rate of 96.4% was achieved.
• Anterior sulcus blunting and graft lateralization were absent in 94.2% of cases.
• Significant hearing improvement was observed, with 74% achieving an air-bone gap closure within 20 dB and 84% experiencing overall hearing gain.

Conclusions:

• Formaldehyde-formed fascia grafts are an effective solution for total tympanic membrane perforations.
• The technique demonstrates excellent graft stability and low complication rates.
• FFF grafts offer a reliable method for both perforation closure and ossicular chain reconstruction, leading to substantial hearing improvement.
