The frontal sinus is frequently a troublesome anatomical obstacle to gain access to the medial anterior cranial base. Surgical approaches to and through the frontal sinus using osteoplastic frontal sinusotomy provide significant advantages to the treatment of lesions of the medial anterior cranial base in addition to the frontal sinus itself. However, appropriate management is necessary to avoid postoperative complications such as cerebrospinal fluid leakage, infection, mucocele formation, and deformity of the forehead.
The advantages and shortcomings of the approach along with the surgical technique are reported based on our clinical experience with pertinent literature review. The approach using the osteoplastic frontal sinusotomy was applied to two cases of osteoma in the frontal sinus, seven cases of craniofacial tumors, a case of chordoma in the sphenoid and clivus, and two cases of intradural lesions in the anterior cranial fossa. The frontal sinus was managed in such a way as to prevent the postoperative complications.
All patients underwent gross total resection of the tumors. With a mean follow-up of 26 months, there were no postoperative complications related to frontal sinus violation.
The neurosurgical approaches via the frontal sinus using osteoplastic frontal sinusotomy are versatile for various lesions of the anterior cranial base in patients with large frontal sinuses. In situations that the frontal sinus have to be violated to approach medial anterior cranial base, the osteoplastic frontal sinusotomy provides such advantages as optimal frontal sinus control to prevent postoperative complications; increases viewing angle with superior trajectory from nasofrontal suture; lower incidence of pnemocephalus due to minimal dural exposure; and excellent cosmesis without frontal burr holes.
