Anal sinusitis, also known as anal cryptitis, is often the source of infectious diseases in the anorectal region. Due to its mild symptoms, it is easily overlooked.

bubble_chart Etiology

The anal sinus opens upward, making it prone to fecal accumulation and infection, which can lead to spasms of the anal sphincter and hinder drainage. The infection is difficult to control, causing inflammation and hypertrophy of the anal papillae.
