ABSTRACT

Background: Traditional surgical approaches to the anterior skull base often involve craniotomy and an extended hospital stay. As experience with endoscopic skull base surgery has grown the techniques and equipment have been found to be adaptable to treat lesions of the anterior skull base. A minimally invasive endoscopic approach theoretically offers the advantage of avoiding the drawbacks of extensive external surgery by minimizing the recovery time and hospital stay. Anterior skull base lesions and sella lesions include Pituitary adenoma, CSF rhinorrhoea, Meningocele, Meningoencephalocele, Meningiomas, Tumours of Nose and PNS with intracranial extension, Lesions of Nasopharynx with intracranial extension, fungal sinusitis with intracranial extension, Mucoceles of PNS with skull base erosion. Materials and methods: In this study, A total of 30 patients who presented with the Anterior skull base lesions and Pituitary adenomas, who filled the inclusion criteria, were chosen for the study. For all the cases a detailed history was collected and necessary evaluations were done. Results: Among the lesions involving the anterior skull base, Fungal sinusitis involving the anterior skull base constitute the most frequent lesion (43.3%) followed by CSF rhinorrhoea (26.6%), Pituitary adenomas (13.3%), Mucocele of PNS (6.66%), Meningoencephalocele (3.33%), ONB (3.33%), JNA with ASB involvement(3.33%) in decreasing order. Conclusion: Lesions involving the anterior skull base are most common being the fungal sinusitis with anterior skull base erosion.
