Objective: Objective: To present a new staging system of tympano-mastoid cholesteatoma that is based on the primary site of pathology in the middle ear (T), its spread to the mastoid (M), and to the surrounding structures either cranial, intra- or extracranial, i.e. presence of complications (C). The TMC staging system is based on correlation of preoperative otoscopy findings with CT examination of the temporal bone.
Setting: Tertiary Care Center.
Patients: We included 120 patients of tympano-mastoid cholesteatoma diagnosed preoperatively, staged and correlated with intraoperative findings.
Results: Preoperative findings has also been correlated with intraoperative findings in 120 consecutive cases operated in the last five years. In 87 percent, pre-operative and intra-operative staging correlated well.
Conclusion: The TMC staging system of cholesteatoma paves the way to a logical roadmap for functional surgery of the middle ear and mastoid, as well it makes the comparison of clinical studies about cholesteatoma meaningful.
