Objective: To investigate whether the use of mesna (sodium 2- mercaptoethanesulfonate), a mucolytic agent capable of breaking disulfur bonds, reduces the frequency of residual cholesteatoma in canal wall up tympanomastoidectomy. Study Design: Retrospective study. Setting: Tertiary care otology and skull base centers. Patients: Two hundred fourteen patients operated on by means of canal wall up tympanomastoidectomy for a middle ear cholesteatoma. Interventions: Planned staged canal wall up tympanoma- stoidectomy. In the study group, the cholesteatoma removal was performed with the support of chemically assisted dissection by using mesna. In the control group, the dissection of the disease was performed by means of a traditional mechanical technique alone.Main Outcome Measures: Prevalence of residual cholesteatoma at the second-stage operation in the 2 groups of study. Results: One hundred eight patients were treated with the an- cillary use of mesna and one hundred six without chemically assisted dissection. A residual cholesteatoma was found in 12 (11.1%) of the 108 patients treated with chemically assisted dissection and in 26 (24.5%) of the 106 patients treated with mechanical dissection. After adjusting for potential confounders, CADISS procedure was associated with a significantly lower risk of having residual cholesteatoma (OR, 0.39; 95% CI, 0.18Y0.84, p = 0.02). Conclusion: This study showed that chemically assisted dis- section by using mesna represents a valid support in reducing the frequency of residual disease in cholesteatoma surgery.

Abstract

Objective: To investigate whether the use of mesna (sodium 2- mercaptoethanesulfonate), a mucolytic agent capable of breaking disulfur bonds, reduces the frequency of residual cholesteatoma in canal wall up tympanomastoidectomy. Study Design: Retrospective study. Setting: Tertiary care otology and skull base centers. Patients: Two hundred fourteen patients operated on by means of canal wall up tympanomastoidectomy for a middle ear cholesteatoma. Interventions: Planned staged canal wall up tympanoma- stoidectomy. In the study group, the cholesteatoma removal was performed with the support of chemically assisted dissection by using mesna. In the control group, the dissection of the disease was performed by means of a traditional mechanical technique alone.Main Outcome Measures: Prevalence of residual cholesteatoma at the second-stage operation in the 2 groups of study. Results: One hundred eight patients were treated with the an- cillary use of mesna and one hundred six without chemically assisted dissection. A residual cholesteatoma was found in 12 (11.1%) of the 108 patients treated with chemically assisted dissection and in 26 (24.5%) of the 106 patients treated with mechanical dissection. After adjusting for potential confounders, CADISS procedure was associated with a significantly lower risk of having residual cholesteatoma (OR, 0.39; 95% CI, 0.18Y0.84, p = 0.02).
