ABSTRACT
Objective To explore the main anatomical factors for relapse in patients underwent radical mas-toidectomy and discuss the preventive measures .Methods A retrospective study was carried out 36 patients who had underwent radical mastoidectomy and 100 patients (100 ears) who had been cured underwent radical mastoidectomy during July 2011 toSeptember 2013 .The patients underwent axial and coronal temporal Computed Tomography (CT) .The incidence of low -lying middle cranial fossa ,high jugular bulb ,anterior locati(36 ears)on of sigmoid si-nus ,dehiscent tympani tegmen ,dehiscent of the facial nerve canal ,large sinus tympani ,low -lying horizontal facial nerve were recorded .Results The incidence of low -lying middle cranial fossa(36 .1% ) ,anterior location of sig-moid sinus(41 .7% ) ,dehiscent tegmen tympani (30 .6% ) ,dehiscent of the facial nerve canal (41 .7% ) ,large sinus tympani(25 .0% ) ,low -lying horizontal facial nerve(22 .2% ) were higher than those of in the normal group .There was no significant difference in high jugular bulb .Conclusion The main anatomical factors for relapse in patients un-derwent radical mastoidectomy were low -lying middle cranial fossa ,anterior location of sigmoid sinus ,dehiscent tegmen tympani ,dehiscent of the facial nerve canal ,large sinus tympani ,low -lying horizontal facial nerve .
