Myringosclerosis in hemodialysis patients with hyperparathyroidism

الملخص EN

Myringosclerosis is the final stage of the middle ear lamina propria inflammation or trauma; it starts with collagen production in excess amounts in the lamina propria of the middle ear mucosa.

Then, hyalinization and calcification occur.

Later on, metaplasia of bone or cartilage can occur.

A similar sequence occurs with hyperparathyroidism in chronic kidney disease.

This study is aimed to detect the prevalence of myringosclerosis in patients of our hemodialysis (HD) unit and find out any association between hyperparathyroidism and myringosclerosis in chronic HD patients.

A total number of 86 patients were selected according to the inclusion criteria.

They were divided into two groups: Group 1 (58 patients myringosclerosis free patients on regular HD), Group 2 (28 patients myringosclerosis-positive patients on regular HD).

No statically significant difference was found in serum parathyroid hormone levels between the two studied groups.

Serum creatinine was significantly higher in Group 2, serum ferritin was significantly lower in Group 2, and mean corpuscular volume of red blood cells was highly significantly lower in Group 2.

Myringosclerosis affects 32% of our HD patients and we could not detect any strong correlation between myringosclerosis and hyperparathyroidism.
