Type 2 thyroplasty (TP2) is a surgery for adductor spasmodic dysphonia (AdSD), and the effectiveness of the surgery depends on the width of cartilage separation and fixation of that width. We experienced a case of breathy hoarseness after initial surgery, and revision surgery was performed and the voice improved. The patient was a 41-year-old woman who was diagnosed with AdSD. To begin, voice therapy was performed, but there was no improvement. Next, TP2 was performed. The thyroid cartilage was split on the midline and two 3.0 mm wide titanium bridges (TBs) were placed on the thyroid cartilage. However, breathy hoarseness appeared after the primary surgery. One month after the first surgery, revision surgery was performed to improve the breathy hoarseness. The two TBs were removed completely, and one 2.0 mm wide TB was placed onto the lower part of the thyroid cartilage. The voice improved to G1R0B1A0S0 and the mora method was 0/21. In TP2, it is important to adjust the width of the cartilage split. If it is too narrow, a spasmodic voice remains, and if it is too wide, the voice becomes breathy. In this case, the voice became breathy after the first surgery, but the revision surgery salvaged the breathy voice. We reconfirmed that TP2 is a reversible surgery and discuss the causes of reoperation and preventive measures.
