True about nasal myiasis ?
**Core Concept**
Nasal myiasis refers to the infestation of the nasal cavity by larvae of flies, particularly the blowfly species. This condition can occur in individuals with compromised nasal mucosa, such as those with nasal trauma, sinusitis, or malignant tumors.
**Why the Correct Answer is Right**
The larvae of blowflies are attracted to necrotic or infected tissues, where they feed on the dead cells and tissue debris. In the case of nasal myiasis, the larvae can penetrate the nasal mucosa and cause significant damage, leading to symptoms such as nasal discharge, bleeding, and difficulty breathing. The infestation can also lead to the formation of a nasal granuloma, a mass of inflamed tissue that forms in response to the larvae's presence.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because nasal myiasis is not typically associated with a primary bacterial infection.
**Option B:** This option is incorrect because the larvae of blowflies are not typically found in the nasal cavity of healthy individuals.
**Option C:** This option is incorrect because nasal myiasis is not a common condition that requires surgical intervention.
**Clinical Pearl / High-Yield Fact**
Nasal myiasis is a classic example of a condition that can occur in individuals with compromised nasal mucosa, and it requires prompt medical attention to prevent further tissue damage and complications.
**Correct Answer: D. Nasal myiasis is a condition that can occur in individuals with compromised nasal mucosa.**
