Abstract OBJECTIVE The pterygopalatine fossa is a relatively small anatomic region. Because of its rich vasculonervous contents and its connections with several intracranial and extracranial compartments, it is of particular surgical interest. Because of its deep localization and despite its small size, however, it can require extensive anatomic approaches, especially for invasive cranial base lesions. We performed a cadaveric study through a minimally invasive endoscopic endonasal approach to the pterygopalatine fossa. METHODS We studied 16 pterygopalatine fossae in eight adult cadaveric heads in which the arteries and veins were injected with latex. For visualization, we used rod-lens endoscopes, 4 mm in diameter and 18 cm in length, with 0-, 30-, 45-, and 70-degree lenses. An endonasal middle meatal transpalatine approach, an endonasal middle meatal transantral approach, and an endonasal inferior turbinectomy transantral approach were used. RESULTS The middle meatal transpalatine approach allows for medial exposure of the pterygopalatine fossa contents, the middle meatal transantral approach allows a lateral view, and the inferior turbinectomy transantral approach allows the widest view and room for surgical maneuvering in the medial and lateral compartments of the pterygopalatine fossa and the infratemporal fossa. CONCLUSION Our anatomic study shows that this approach can be considered a valid minimally invasive option to approach pterygopalatine fossa lesions.

Abstract OBJECTIVE: The endoscopic endonasal approach offers the opportunity to reach the ptery-gopalatine fossa, the lateral recess of the sphenoid sinus, and other areas of the cranial base through a minimally invasive approach. This study compares the anatomy of these areas when observed through an endoscopic endonasal view with the anatomy of the same regions as they appear in computed tomographic scans. The aim was to identify and correlate the corresponding anatomic structures, providing the surgeons with anatomic landmarks to guide them when operating in these areas through an endoscopic endonasal approach. METHODS: An anatomic dissection of six fixed cadaver heads was performed by an endoscopic endonasal approach. A step-by-step comparison of endoscopic and radiological images was made to identify the landmarks of the surgical field. RESULTS: The step-by-step comparison of endoscopic and radiological images acquired during the endoscopic endonasal approach to the lateral recess of the sphenoid sinus via the pterygopalatine fossa allowed the identification of all the relevant anatomic landmarks of the procedure. CONCLUSION: The endoscopic endonasal approach via the pterygopalatine fossa offers direct, minimally invasive access to the lateral recess of the sphenoid sinus, which can be monitored in each phase through consistent radiological imagery.

Objective. Meningiomas and schwannomas represent a subset of primary intracranial tumors that are rarely identified exclusively in the paranasal sinuses. Here, we describe our experience with minimally invasive endoscopic endonasal approaches for the treatment of these tumors. Methods. We retrospectively reviewed the clinical, surgical, and radiographic characteristics of adults with pathologically confirmed sinonasal meningiomas and schwannomas located within the paranasal sinuses that were resected via an expanded endoscopic endonasal approach. Results. Five patients (1 male, 4 females) underwent an endoscopic endonasal approach for resection of sinonasal tumor. Clinical symptomatology most commonly included nasal obstruction, in addition to headache, jaw pain, anosmia, and chronic rhinosinusitis. Tumors were located exclusively within the sinonasal cavity and were on average 2.2 cm (range 1.4–3.8 cm). Pathology revealed 2 cases of meningioma and 3 cases of schwannoma. No evidence of tumor recurrence occurred over average followup of 1.5 years (range 0.11–3.9 years). Conclusion. Our case series suggests that an expanded endoscopic endonasal approach with a combined neurosurgical-otorhinolaryngologic team for the resection of sinonasal meningiomas and schwannomas offers an effective treatment option. Further studies that include a larger number of patients over a longer follow-up period are required to compare outcomes between minimally invasive and open approaches.

Indications For Treatment

OBJECT The transoral approach is the gold standard for ventral decompression of the brainstem caused by craniovertebral junction (CVJ) pathology. This approach is often associated with significant morbidity, related to swallowing and respiratory complications. The endoscopic endonasal approach was introduced to reduce the rate of these complications. However, the exact role of this approach in the treatment of CVJ pathology is not well defined. METHODS A comprehensive literature search was performed to identify series of patients with pathology of the CVJ treated via the endoscopie endonasal approach. Data on patient characteristics, indications for treatment, complications, and outcome were obtained and analyzed. RESULTS Twelve studies involving 72 patients were included. The most common indications for treatment were rheumatoid pannus (38.9%) and basilar invagination (29.2%). Cerebrospinal fluid leak was found in 18% of cases intraoperatively and 4.2% of cases postoperatively. One case of meningitis complicated by sepsis and death represents the procedure-related mortality of 1.4%. Of the patients without preoperative swallowing impairment, 95% returned to oral feeding on the 3rd postoperative day. Ninety-three percent of patients experienced improvement in neurological symptoms after the procedure. CONCLUSIONS The endonasal endoscopie approach is effective for the treatment of neural compression caused by CVJ pathology. It offers advantages such as lower rates of postoperative dysphagia and respiratory complications when compared with the more traditional transoral approach. However, these 2 approaches should be seen as complementary rather than alternatives. Patient-related factors as well as the surgeon’s expertise must be considered when making treatment decisions.
