ABSTRACT
Background: The principal advantages of mastoid cavity obliteration are 1) reduced nitrogen-absorbing mucosa in the mastoid cavity preventing recurrence of retraction cholesteatoma in patients with eustachian tube dysfunction, 2) elimination of mastoid cavity preventing accumulation of squamous epithelium and bowel infection . The size of the surgical cavity can be diminished using obliteration to create a small cavity that is self cleaning and easily maintained. Both autologous and synthetic materials have been used for obliteration. Materials such as free graft, fat, cartilage, bone chips, bone pâté, hydroxyapatite, and periostio-muscular flaps are used. Aim of work: To evaluate the benefit from mastoid obliteration in cholesteatoma surgery. Patients and methods: This study was applied on 12 patients that have middle ear cholesteatoma.mastoidectomy had been done then obliteration either by natural or synthetic fillers had been done and followed up by DW-MRI Results: The patients consisted of 6 females (50%) and 6 males (50%). Their ages ranged from 14 to 52 years old.
Conclusion: Mastoid obliteration can be used in combination with either the ICW or CWD techniques. It gives favourable long-term results. It is certainly the treatment of choice for persistent discharging mastoid cavities.
