|---|---|---|---|---|
| TEF widening | 414 (80) | 341 (80) | 73 (78) | 0.574 |
| TEF granulation | 45 (9) | 37 (9) | 8 (9) | 0.951 |
| TEF inflammation | 52 (10) | 43 (10) | 9 (10) | 0.874 |
| VP pulled into TEF | 14 (3) | 12 (3) | 2 (2) | 0.706 |

| Other and not specified | 35 (7) | 30 (7) | 5 (5) | 0.543 |
*The data does not add up to 100% as a patient may have experienced more than one type of complication;** **Test χ2, p<α statistically significant; TEF, tracheoesophageal fistula; VP, voice prosthesis.
