Management of Attic Cholesteatoma While Preserving Intact Ossicular Chain; “Modified Bondy Technique” vs. “Canal Wall Up Mastoidectomy with Tympanoplasty Type I & Scutumplasty” / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: The aim of this study is to evaluate the clinical outcomes of two surgical techniques-modified Bondy technique and canal wall up mastoidectomy with tympanoplasty type I and scutumplasty (CWUM/T1)-to remove attic cholesteatoma while preserving ossicular chain intact. SUBJECTS AND METHOD: A retrospective study was performed on 23 surgical cases for the attic cholesteatoma with postoperative audiometry data of more than six months after surgery. The patients' postoperative clinical features and audiometric results were compared between the two surgical groups. RESULTS: Out of 23 patients, CWUM/T1 was performed in 13 cases and modified Bondy technique was used in 10 cases. There were no significant differences for the preoperative and postoperative audiograms between the two groups. But air-bone gap increased significantly after CWUM/T1 while it decreased after modified Bondy technique. Three cases with postoperative problems were seen after CWUM/T1 (recurrent cholesteatoma, pars tensa adhesion, recurrent otitis media with effusion). Two cases with postoperative problems were found after modified Bondy technique (mild attic retraction, pars tensa retraction). CONCLUSION: Both surgical techniques seem to be adequate to treat attic cholesteatoma while preserving intact ossicular chain. Given good postoperative hearing results and stability of open cavity against recidivism, the modified Bondy technique seems to be a good choice for the attic cholesteatoma with intact ossicular chain when mastoid is not highly pneumatized.
