Table 1 Aspiration prevention surgeries
Aspiration prevention surgeries | Types of anesthesia | Operative time | Amount of bleeding | Risk of suture failure | Possible postoperative speech | UES opening effect | |
|---|---|---|---|---|---|---|---|
Surgeries to remove the larynx | Total laryngectomy [14–19] | G | > 2 h | Relatively large | Relatively low | Eso-S/VP | + |
Central-part laryngectomy [20–24] | G, L | ≒ 2 h | Small | Low | Eso-S/VP | + | |
Surgeries to change the tracheal structure | Tracheoesophageal diversion [4, 25–29] | G | > 2 h | Small | Relatively low | Eso-S/VP | − |
Laryngotracheal separation [30–34] | G, L | ≒ 2 h | Small | Low | − | − | |
Tracheal flap method [35, 37, 38] | G, L | ≒ 2 h | Small | Low | − | − | |
