The clinical observation on 52 cholesteatoma otitis media patients by the surgery of mastoid muscle periosteum valvuloplasty after modified radical mastoidectomy

Abstract

Objective To investigate the clinical effects of the surgery of mastoid muscle periosteum valvuloplasty after modified radical mastoidectomy treatment of cholesteatoma otitis media.Methods 52 cases (52 ears)cholesteatoma otitis media patients for the observation group were collected.The patients in the observation group were treated by mastoid muscle periosteum valvuloplasty after modified radical mastoidectomy.49 cases (49 ears) for the control group were treated by concomitant mastoidectomy and the classic conchaplasty cavity angioplasty.Results Patients were followed up for 1 year.38 ears were dry in control group(77.6％),8 ears were recurrenced(16.3％),regular clean-up of surgical cavity at least 3 months postoperative.50 ears were dry in observation group (95.2％),dry ear rate was significantly higher (x2 =12.374,P =0.000) ;1 ears was recurrenced(2.4％),the recurrence rate was significantly reduced (x2 =11.966,P =0.000) ; Operative cavity after complete epithelialization no longer need to be cleaned regularly; No postoperative complications (such as periosteal flap or pinna cartilage of the mastoid muscle necrosis,facial paralysis,dizziness)were occurred,the prognosis was good.Conclusion The surgery of mastoid muscle periosteum valvuloplasty after modified radical mastoidectomy treatment of otitis media with cholesteatoma is safe and effective,which is worthy of promotion.
