A 35-year-old patient undergoes tympanoplasty for a large central perforation. The surgeon uses temporalis fascia graft placed medial to the tympanic membrane remnant. Which type of tympanoplasty technique is this?

• A Underlay technique (medial graft) ✓
• B Overlay technique (lateral graft)
• C Onlay technique
• D Sandwich technique

Explanation

In the underlay (medial graft) technique, the graft is placed medial to the tympanic membrane remnant and the handle of malleus, resting on the medial surface. The overlay (lateral graft) technique places the graft lateral to the malleus handle. The underlay technique has advantages of better graft support and lower risk of blunting at the anterior angle.
