Nasopharyngeal Angiofibroma

Pterygopalatine fossa (PPF) is a difficult-to-access anatomic area located behind the posterior wall of the maxillary sinus. Juvenile nasopharyngeal angiofibroma (JNA) often affects this area, and the management of feeding artery to the tumor is important in the surgery. Endoscopic endonasal approach to the PPF without endangering all other nasal structures is useful in the management of JNA. We describe a new approach to the PPF, endoscopic transturbinate approach, which is effective in the management of JNA. Submucous inferior turbinoplasty was performed, and sphenopalatine artery, the feeder to the tumor, was identified at the sphenopalatine foramen. The posterior wall of maxillary sinus was removed. Internal maxillary artery was identified in the PPF and was ligated with a hemoclip. The tumor in the PPF was pushed into the nasal cavity. These procedures were all performed via submucous turbinate tunnel. Then, the tumor was successfully removed in en bloc from the nasal cavity by transnasal approach without ethmoidectomy. This approach improves accessibility and visualization in the PPF and potential to reduce intraoperative bleeding due to ligation of the feeder safely without touching the tumor. Endoscopic transturbinate approach is effective in the management of early stage of JNA.

Difficult Area

<p class="abstract">The pterygopalatine fossa is a difficult area for surgical access and lesions in this area traditionally advocated open external trans maxillary approaches. With endoscopic techniques, it is possible to not only access and explore this area but also plan complete excision of lesions in the pterygopalatine fossa. We present a case report of a 26-year-old lady with complaints of pain in the area of the left cheek for 6 months. She had no other co-morbidities. On clinical examination, no abnormality was detected.  Radiological examination with magnetic resonance imaging showed a lesion possibly a schwannoma in the left pterygopalatine fossa behind the left maxillary sinus. Complete excision was achieved using trans nasal endoscopic technique through the left maxillary sinus. Histopathological examination confirmed the diagnosis of schwannoma.  Post-operative period was uneventful and she was free from any pain and neurological symptoms on subsequent follow up. Schwannomas in the pterygopalatine fossa are rare entities. Endoscopic techniques are safe and effective in accessing the pterygopalatine fossa for excision of lesions situated in this area. This technique obviates the need for external facial incisions or intra oral incisions and helps in good surgical outcomes and quick healing and recovery.   </p>
