This retrospective study evaluates the effectiveness of frontal debossing by comparing pre- and postoperative volumetric and morphometric data. Sixteen patients who underwent frontal debossing at the University Hospital Basel between 2020 and 2024 were included. Preoperative and postoperative CT or CBCT scans were used to assess volume changes in the frontal bone, frontal sinus, and bilateral supraorbital rims. Additionally, changes in the nasofrontal angle were measured. Significant volume reductions were observed in all analyzed structures: left supraorbital rim (mean reduction 792.28 mm<sup>3</sup>), right supraorbital rim (726.19 mm<sup>3</sup>), frontal bone (2930.81 mm<sup>3</sup>), frontal sinus (2508.84 mm<sup>3</sup>), and combined frontal structures (3251.83 mm<sup>3</sup>). The nasofrontal angle increased by an average of 21.71°, indicating a substantial improvement in upper facial contour.

From October 2020 to January 2024, 34 patients with secondary bilateral cleft lip nasolabial deformities were included, with ages ranging from 16 to 36 years. The orbicularis oris muscle reorientation technique was employed to address nasolabial deformities.

The Ls-Sto thickness increased from an average preoperative of 7.02 ± 2.63 mm to 11.33 ± 3.04 mm. The extremely large columellar base (CobR-CobL) was reduced by 24.5 %, and the Cupid's peak distance (ChpR-ChpL) was reduced by 18 %.
