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. |
