Removal of the Posterior Wall of the Sphenoid Sinus During Trans-sellar Skull Base Surgery: The Meniscus Sign
Trans-sellar surgical approaches can be difficult and unpredictable. Tumors can distort the appearance of the posterior wall of the sphenoid sinus and a surgeon's concerns for avoiding the proximal vascular structures of the region may compromise access for the neurosurgical portion of the operation. Bone removal from the sellar dura is sometimes suboptimal. The meniscus sign is a convenient and reliable method for removal of the posterior wall of the sphenoid sinus during trans-sellar skull base surgery. It is a safe technique that maximizes bone removal and surgical access between the cavernous sinuses and internal carotid arteries. The senior author has employed the meniscus sign in trans-sellar surgery for over 15 years, noting that the technique has been free of surgical complications, reproducible amongst trainees, and reliable in safely providing maximum exposure for the intradural portion of the operation.
期刊介绍：
This large-size, atlas-format journal presents detailed illustrations of new surgical procedures and techniques in otology, rhinology, laryngology, reconstructive head and neck surgery, and facial plastic surgery. Feature articles in each issue are related to a central theme by anatomic area or disease process. The journal will also often contain articles on complications, diagnosis, treatment or rehabilitation. New techniques that are non-operative are also featured.
