RESUMO
PURPOSE: To compare the relationship between the variable "complication" and the other variables of middle ear cholesteatoma classifications (STAMCO, ChOLE, and SAMEO-ATO). METHODS: Retrospective study of 110 patients that underwent 132 middle ear surgeries between the 1 January 2012 and the 31 December 2019 for chronic otitis with cholesteatoma classified according to STAMCO, ChOLE, and SAMEO-ATO classifications in a tertiary health care centre. RESULTS: Older age, male gender, STAMCO-T, and SAMEO-ATO [O1, T, O2, (s -)] and mastoid involvement (STAMCO-M and ChOLE-Ch) were associated with an increased risk of complication report. CONCLUSIONS: In our series, statistical analysis pointed out a relationship between surgical complications and age, gender, site, mastoidectomy type, and ossicular chain status at surgery. The choice of variables to be recorded for cholesteatoma staging should be carefully balanced, considering that "complication" variable could be a repetitive item.
