Pharyngeal angio fibroma is treated with:
**Core Concept**
Pharyngeal angiofibroma, also known as juvenile nasopharyngeal angiofibroma, is a rare, benign tumor that primarily affects adolescent males. It is characterized by its vascular nature, arising from the nasopharynx and invading surrounding structures due to its rich blood supply.
**Why the Correct Answer is Right**
The correct treatment for pharyngeal angiofibroma involves surgical excision, often through endoscopic or external approaches, to remove the tumor and its associated blood vessels. This is typically performed by an experienced head and neck surgeon. The tumor's vascular nature makes it challenging to treat, and surgical excision is usually the most effective option.
**Why Each Wrong Option is Incorrect**
**Option A:** Radiation therapy is not a primary treatment for pharyngeal angiofibroma due to its benign nature and potential for long-term complications.
**Option B:** Chemotherapy is not a standard treatment for pharyngeal angiofibroma, as the tumor is not responsive to systemic chemotherapy agents.
**Option C:** Embolization may be used as an adjunct to surgical treatment to reduce blood flow to the tumor, but it is not a standalone treatment.
**Clinical Pearl / High-Yield Fact**
Pharyngeal angiofibroma often presents with nasal obstruction, epistaxis, and facial deformity due to its invasive nature. Early recognition and treatment are crucial to prevent complications and preserve facial function.
**Correct Answer:** C. Surgical excision.
