Magnetic Resonance Imaging in Primary and Secondary Septorhinoplasty
02 June 2008 (online)
The authors emphasize the importance of MRI as a means to functionally evaluate patients in primary (PR) and secondary (SR) rhinoseptoplasty. Forty-eight subjects were appraised who underwent various types of corrective nose surgery: 31 PR, 12 SR, 4 iatrogenic perforations, and 1 dermoid cyst of the nasal dorsum. MRI allows the nasal structures at the level of the valve to be visualized, as well as the medial and lateral walls of the nasal fossa in all of its components. MRI studies improve pre-surgical evaluation (alar cartilages, interdomal distance, and valvular configuration), and the exam of structures and anomalies which are hard to evaluate by the rhinoscopy (turbino-septal-synchias, perforations, losses of bone-cartilaginous substance). Moreover, through MRI the nasal respiratory surface (NRS) is determined and used by the authors to quantify the improvement of the postsurgical nasal respiratory function. All of these points gain importance during the planning of primary, secondary, and/or corrective surgery.
