“…23 studies recruited patients with dry ear status (11,18–22,24–29,31–33,35,36,38–40,42–44), three studies with wet ear status (30,34,37), and 7 studies with both dry and wet ear status (7–10,12,13,41). Some studies only included microscopic myringoplasty (7–10, 12,13,18–21,24,26,31–33,35,37,40–42), some only endoscopic myringoplasty (27,28,30,34,38,44) and some included both types (11,19,20,24–31). The underlay technique was used in all studies, with 4 studies also using the overlay technique (21,24,29,32).…”
