FIG. 14. Vertigo control: Forest plot for mastoid shunt with si- lastic with Category A/B vertigo control at a minimum of 24 months of follow-up.

FIG. 16. Vertigo control: Forest plot for mastoid shunt without si- lastic with Category A/B vertigo control at a minimum of 24 months of follow-up.

of patients (Fig. 13). Mean PTA worsened by 6.0 dB (range, 0.0 Y 13.3 dB).

of patients (Fig. 15). Mean PTA worsened by 6.2 dB (range, 4.0 Y 13.3 dB).

Mastoid Without Silastic. Vertigo: Four articles, total- ing 335 patients, were analyzed to determine the efficacy of mastoid shunting without silastic in controlling ver- tigo. Mean follow-up was 40.8 months (range, 24 Y 72 mo). Complete or substantial (Category A/B) vertigo control was achieved in 79.0% (95% CI, 63.8% Y 90.9%) of patients (Fig. 16). Hearing: Two articles, totaling 240 patients, were ana- lyzed to determine the efficacy of mastoid shunting with- out silastic in hearing preservation. Mean follow-up was 49.8 months (range, 24 Y 72 mo). Postoperative hearing was unchanged or improved in 79.8% (95% CI, 68.1% Y 89.3%) of patients (Fig. 17). We were unable to calculate mean dB PTA change.

Mastoid Shunt With Silastic Versus Mastoid Shunt without Silastic

Mastoid With Silastic. Vertigo: Nine articles, totaling 631 patients, were analyzed to determine the efficacy of mastoid shunting with silastic in controlling vertigo. Mean follow-up was 40.7 months (range, 24 Y 60 mo). Complete or substantial (Category A/B) vertigo con- trol was achieved in 75.3% (95% CI, 71.8% Y 78.6%) of patients (Fig. 14). Hearing: Seven articles, totaling 324 patients, were an- alyzed to determine the efficacy of mastoid shunting with silastic in hearing preservation. Mean follow-up was 38.8 months (range, 24 Y 132 mo). Postoperative hearing was stable or improved in 64.4% (95% CI, 59.0% Y 69.5%)

FIG. 15. Hearing outcomes: Forest plot for mastoid shunt with silastic with hearing improved or stable at a minimum of 24 months of follow-up.

FIG. 17. Hearing outcomes: Forest plot for mastoid shunt without silastic with hearing improved or stable at a minimum of 24 months of follow-up.
