Table 3 Variance analysis of average bone conduction thresholds and presence of balance disturbance in late 1-year follow-up after surgical treatment in group 2a.
| Disturbance of balance | n | Postoperative BC at 1 year (dB) | P | BC preop (dB) | ΔBC (dB) | ||||
|---|---|---|---|---|---|---|---|---|---|
| Average | SD | Me | Min | Max | |||||
| Absent | 33 | 11.6 | 0.9 | 10.6 | 10.0 | 11.3 | <0.05 | 21.3 | 9.7 |
| Present | 2 | 23.5 | 7.4 | 23.8 | 10.0 | 37.5 | 22.8 | −0.7 | |
| Postoperative BC – average bone conduction thresholds after surgery; BC – bone conduction threshold; BC preop – average bone conduction threshold before surgery; ΔBC – change in bone conduction; dB – decibel; SD – standard deviation; Me – median; min – minimum; max – maximum; n – number of patients. | |||||||||
