Trans-superior meatal approach to the sphenoid sinus.

We have recently operated on patients with isolated lesions of the sphenoid sinus using the trans-superior meatal approach that we developed. This may be one of the least traumatic methods for treating the isolated lesions of the sphenoid sinus. Though it has a few limitations, this approach provides a direct and safe short-cut to the sphenoid sinus and is well tolerated by the patient under local anesthesia. We present our experience with transnasal trans-superior meatal approach to the sphenoid sinus and introduce the technique with case reports.
