Abstract

The nasopharynx lies deep and central in the skull. It is the region located behind the nasal cavities and above the soft palate. The undersurface of the body of the sphenoid bone forms the slanting roof that merges inferiorly with the posterior wall. The floor of the nasopharynx opens downward into the oropharynx at the level of the soft palate. Tumours arising from the nasopharynx could be benign or malignant. The most common benign tumour is angiofibroma, while the main malignant neoplasm is nasopharyngeal carcinoma. Surgical excision of JNA is considered the primary treatment modality. Surgery has a limited role in the treatment of nasopharyngeal carcinoma because of the tumor's high degree of radiosensitivity and the anatomic barriers to surgical access. Resection of lesion in the nasopharynx is a challenge due to this anatomical complexity and the surrounding vital structures. Preoperative radiologic evaluation of the tumor is important in planning the surgical approach. Although it is entirely accepted that surgery is the treatment of choice for the majority of JNAs, the surgical approach is still under discussion. Several open surgical approaches have been performed. Each approach has its advantages and disadvantages.
