ABSTRACT
Objective: To determine the stage of middle ear cholesteatoma of patients who underwent
middle ear surgery at the Southern Philippines Medical Center from January to December 2019,
based on European Academy of Otology and Neurotology / Japan Otological Society (EAONO/
JOS) system.
Methods:
Design: Case Series
Setting: Tertiary Government Hospital
Participants: A total of 42 charts were included in the study
Results: Of the 42 cases evaluated, congenital cholesteatoma was seen in 4 while acquired cholesteatoma was noted in 38, (further subdivided into 34 retraction pocket cholesteatoma and 4 non-retraction pocket/traumatic cholesteatoma). A majority (57%) had Stage II cholesteatoma (mass occupying at least two sub-sites in the middle ear) at the time of surgery. Eight (19%) had stage I cholesteatoma (confined to one sub-site), five (12%) had stage III cholesteatoma evidenced by extracranial complications such as subperiosteal abscess and erosion of the semi[1]circular canals. Stage IV cholesteatoma was seen in 5 (12%) presenting with intracranial abscess. Canal wall down mastoidectomy was the most common surgical approach performed. The sinus tympani (S2 ) was the most commonly involved difficult to access site across all classifications of middle ear cholesteatoma (60%).
Conclusion: Our study provided an initial profile of the stages and severity of middle ear cholesteatoma in our institution based on actual surgical approaches. Such a profile can be the nidus for a database that can help us to understand disease prevalence and compare local surgical practices with those in the international community.
