| Abstract | ||
| The incus long process is particularly vulnerable to damage from infection and trauma due to its anatomic location and poor blood supply. Bone cement, such as glass ionomer cement, can be used to stabilize the incus graft or other prostheses in ossiculoplasty. This study compared hearing outcome between classic incus interposition and incus interposition stabilized by bone cement due to defects in incus long process caused by chronic suppurative otitis media (CSOM). The current study included 64 cases with necrosed incus long process. Cases were allocated into 2 equal groups; group A underwent classic microscopic incus interposition and group B underwent incus interposition stabilized with bone cement. Threshold levels of air conduction (AC), bone conduction (BC) and Air bone gap (ABG) were obtained. The duration of the operation was significantly longer in group B. The post-operative AC and ABG threshold at different frequencies were significantly lower among group B cases. The complications in group B were taste disturbance in 18.8%, vertigo in 9.4%, otorrhea in 12.5% and wound dehiscence in 3.13%. We concluded that incus interposition techniques with or without the use of bone cement were associated with significant improvement in different audiological parameters in cases suffering from defects in incus long process. The use of bone cement was associated with significant improvement as compared to incus interposition alone | ||
