True about nasal myiasis is?

In nasal myiasis, initially, the patient presents with epistaxis. On the fouh day, maggots crawl out of the nose and foul smell surrounds him. Can cause extensive destruction to the nose, sinuses, soft tissue of the face, palate and eyeball. Fistulae may form in the palate or around the nose. Death may occur from meningitis. Saline installation is only helpful in the removal of the slough, crusts, and dead maggots. Chloroform water and oil can be used instead.
