A retrospective comparative study was conducted on patients diagnosed as low nose with paranasal concavity between June 2017 and June 2021, with a total of 56 patients followed up successfully. The control and observation groups were established according to whether the paranasal augmentation was performed. Demographic data were collected. Cosmetic enhancement was quantitatively evaluated by sagittal planimetry, establishing related anatomical landmarks and measuring columella base prominence (CBP) and alar base prominence (ABP). Subjective evaluation concluded the patient-reported satisfaction (FACE-Q-Rhinoplasty Module and Facial Appearance Module) and the third-party physician assessment (Global Aesthetic Improvement Scale, GAIS).<\/jats:p><jats:p>Significant improvements in CBP and ABP were reported both in the control and the observation group (p\u2009&lt;\u20090.01). In postoperative intergroup comparisons, the observation group was superior to the control group regarding ABP values (2.5\u2009\u00b1\u20090.75\u2009degrees, p\u2009&lt;\u20090.01), FACE-Q-Facial scores (7.49\u2009\u00b1\u20093.70, p\u2009&lt;\u20090.05), and GAIS scores (p\u2009&lt;\u20090.05). However, no statistical difference was found in CBP values and FACE-Q-Rhinoplasty scores. Paranasal augmentation-related complications included asymmetry of alar bases (6.9%) and facial or intraoral foreign body sensation (34.5%). This study affirmed that paranasal augmentation using diced costal cartilage in rhinoplasty is a safe procedure effective in remedying paranasal concavity and improving facial satisfaction.<\/jats:p><jats:p>\n          Level of
