Background
Adult idiopathic membranous obstruction of the foramen of Monro is an extremely rare condition that can be effectively treated with endoscopic foraminoplasty. A unilateral or bilateral foraminoplasty is performed if one or both of the foramina of Monro are obstructed, respectively. Endoscopic septum pellucidotomy is usually used in combination with the foraminoplasty.
Methods
The operative chart and video of one of our patients undergoing endoscopic treatment for adult idiopathic membranous obstruction of the foramen of Monro were retrieved from our database and reviewed. A description of the surgical technique was then formulated.
Conclusions
The surgical technique of endoscopic foraminoplasty plus septum pellucidotomy for adult idiopathic membranous obstruction of the foramen of Monro is described.
