Stage 2B nasopharyngeal angiofibroma best treated with –
**Core Concept**
Stage 2B nasopharyngeal angiofibroma is a type of benign tumor characterized by its vascular nature and aggressive growth pattern, primarily affecting adolescent males. The tumor's location and potential for bleeding make surgical intervention crucial.
**Why the Correct Answer is Right**
The best treatment option for Stage 2B nasopharyngeal angiofibroma involves a multidisciplinary approach, but surgical resection is the primary modality. The correct answer involves endoscopic endonasal surgery (EES) with or without preoperative embolization. EES is preferred due to its minimally invasive nature, allowing for better visualization and preservation of surrounding structures. Embolization is often performed to reduce blood loss during surgery.
**Why Each Wrong Option is Incorrect**
**Option A:** External approach (e.g., transmaxillary incision) may be associated with higher morbidity and longer recovery times, making it a less favorable option.
**Option B:** Radiation therapy is not typically used as a primary treatment for nasopharyngeal angiofibroma due to its potential long-term effects on growth and development.
**Option C:** Chemotherapy is not a standard treatment for nasopharyngeal angiofibroma, as these tumors are generally resistant to systemic therapy.
**Clinical Pearl / High-Yield Fact**
Endoscopic endonasal surgery with preoperative embolization is a preferred treatment modality for Stage 2B nasopharyngeal angiofibroma due to its minimally invasive nature and reduced risk of complications.
**Correct Answer: D. Endoscopic endonasal surgery (EES) with or without preoperative embolization.**
