The endoscopic modified Lothrop procedure (EMLP) has become a frequently utilized procedure in rhinologic surgery.

One of the most serious complications of the procedure is cerebrospinal fluid leak, which may occur due to lack of recognition of the anterior skull base in the region of the first olfactory filum (FOF), or direct injury to the FOF itself.

Objectives:

To evaluate the position of the head of the middle turbinate (MT) relative to the FOF, which is an important landmark in the EMLP.

Methods:

A series of previously obtained patient computed tomography scans of the sinus were reviewed. A reproducible process was implemented to obtain the measurements. First, the FOF was identified on an axial series.

Using a localization feature of the radiographic software, this anteroposterior (AP) position could be visualized in a coronal plane.

Subsequently, the MT was viewed in a sagittal plane, where a measurement between the head of the MT and the AP position of the FOF could be performed.
