ABSTRACT
In this study we aimed to investigate epidermal growth factor (EGF), interleukin (IL1)-α and IL-6 levels, and hematological parameters in the serum samples of patients with chronic cholesteatomatous otitis media (CCOM). This prospective included 40 patients who underwent surgery due to CCOM between June 2020 and May 2021. The stage of middle ear cholesteatoma was determined on each chart using the EAONO/JOS system. The control group comprised of 30 adults who were scheduled for septoplasty over the same period in our hospital, had no otological complaints, and had normal otological findings. The demographic, clinical, and laboratory data of the patients were obtained from the electronic medical record system of our hospital. The serum EGF, IL1-α and IL-6 levels, and hematological parameters (neutrophil-lymphocyte ratio (NLR) and mean platelet volume (MPV)) were compared between the CCOM and control groups. Seven patients had Stage 1 and 33 patients had Stage 2 middle ear cholestatoma. There was no statistically significant difference between the CCOM and control groups in terms of age and gender (p=0.092 and p=0.616, respectively). The serum EGF and IL1-α levels of the CCOM group were statistically significantly higher than those of the control group (p=0.047 and p=0.013, respectively). No statistically significant difference was observed in the serum IL-6 levels of the CCOM and control groups (p=0.675). There was also no significant difference between the CCOM and control groups in terms of the mean NLR and MPV values (p=0.887 and p=0.164, respectively). There was no significant difference between the Stage 1 and Stage 2 cholesteatoma subgroups in terms of the mean EGF, IL1-α, IL-6 levels (p=0.204, p=0.557 and p=0.613, respectively), and the mean NLR and MPV values (p=0.487, p=0.439, respectively). Increased serum EGF and IL1-α levels in patients with CCOM suggest that these cytokines may play a role in cholesteatomatous epithelial hyperproliferation.
