However, diseases secondary to adenoid hypertrophy, such as sinusitis and otitis media, might lead to fever.

Therefore, clinically, it is essential to distinguish between different stages and conditions of adenoid hypertrophy to manage it correctly. Simply put, adenoid hypertrophy does not cause fever by itself.
