OBJECTIVE: The aim of this study is to assess the distance between the anterior nasal spine and the sphenoidal rostrum related to the LeFort I surgery in a Turkish population sample. MATERIAL AND METHODS: We retrospectively reviewed multidetector computerized tomography (MDCT) scans of 209 patients (134 males and 75 females). The images were obtained on a 64-MDCT scanner. The imaging parameters were 0.5 × 64 mm slice thickness, 0.5/0.3 mm increment, 120 kV, 250 mAs, 0.5 sn rotation time, 0.641 pitch, and 512 matrix. The distance between the anterior nasal spine and the sphenoidal rostrum was assessed with the Vitrea 2 software program. RESULTS: The study group consisted of 134 male (mean age 57.90 ± 5.86) and 75 female (mean age 54.84 ± 4.31) patients. The distance between the anterior nasal spine and the sphenoidal rostrum was ranging between 40.4 and 70.9 mm (average 58.3 ± 5.9) in males and 45.0 and 63.2 mm in (average 55.2 ± 4.3) females. In addition, no statistically significant differences were found between genders. CONCLUSION: The results of the current study showed that after 40 mm proceeding of the ball end nasal osteotome, the surgeons must be aware of penetrating the sphenoidal rostrum.
