Inner ear infections - is this something common that occurs after otoplasty ?

I had my otoplasty about 2 years ago. My surgery went great and am happy with the results. But I keep getting recurrent inner ear infections with vertigo if my sinuses become congested at all. My first infection was a month after surgery with multiple infections the following year. I never had this issue prior to surgery. It has started to really impede my daily life. My ear gets sharp pains, fullness, muffled hearing, and severe vertigo when it happens. Is this something common that occurs?
