Cholesteatoma is defined as the presence of stratified squamous epithelium in the middle ear cleft and/or temporal bone.
The clinical presentation of cholesteatoma includes offensive otorrhea, hearing loss and complications such as facial palsy, vertigo, meningitis and brain abscess
Imaging modalities include High Resolution CT scan (HRCT) petrous bone, MRI petrous bone especially Diffusion Weighted MRI (DW-MRI) non Echo Planar image (Non-EPI)
Classical Surgical approaches to cholesteatoma include Canal Wall Up Mastoidectomy (CWUM) and Canal Wall Down Mastoidectomy (CWDM)
Recently, Endoscopic Assisted CWUM andTranscanal Endoscopic Ear Surgery (TEES) have been implemented to merge the merits of canal wall up and canal wall down approaches.
The addition of endoscope has led to significant reduction of cholesteatoma recidivism compared to pure microscopic tympanomastoidectomy.
Aim of the work
The aim of this study is to evaluate the outcomes of cholesteatoma surgery in three groups of patients namely: Endoscopic assisted CWUM, TEES and CWDM.
