Abstract
Cholesteatoma is a an abnormal, noncancerous, destructive, erosive and expanding growth, consisting of keratinizing squamous epithelium in the middle ear and/or mastoid process.This can result in the destruction of the bones of the middle ear (ossicles), as well as growth through the base of the skull into the brain. Its causative risk factors are poorly understood.The disease is treated surgically often followed by a second-look procedure to check for residual tissue or recurrence. Traditionally, this has been performed using microscopes; however, a novel technique using endoscopes offers a new perspective on our understanding of anatomy, pathogenesis and surgical approaches. Endoscopic ear surgery represent a promising, feasible, minimally invasive and conservative technique.The present study aimed to compare the outcomes of endoscopic versus microscopic approach in cholesteatoma surgery.The study recruited 80 patients suffering from chronic suppurative otitis media with attic cholesteatoma and attico-antral cholesteatoma. Comparison between the studied patients regarding the basic and preoperative data revealed no statistically significant differences. Of note, patients included in the present study comprised 52 males (65.0 %) and 28 females (35.0 %). In the present study, there were no significant differences between the studied groups regarding the operative time
