Background: Non-surgical rhinoplasty is one of the best choices in mild cases of the saddle nose, and it represents a solution for the aesthetical amelioration of facial deformity; nevertheless, in most critical cases, surgical intervention is still required. This study reports the experience and results of a single facial plastic surgeon (M.G.) using a non-surgical technique for the correction of saddle noses in a large cohort of patients. Methods: This retrospective study assesses all patients injected from January 2017 through October 2023 in private clinics in Milan (Italy), London (UK), and Dubai (UAE). All patients were followed up for 12 months. The harvested adipose tissues were processed with different systems and with or without acoustic wave therapy (AWT). The extracted products have been characterized in terms of cellular yield and cell growth. Ninety-seven patients were injected with adipose-derived products or hyaluronic acid (HA). Patients were followed up for 12 months, and satisfaction data were analyzed. Results: The stem cells obtained from the patients who previously received AWT displayed a statistically higher cell growth ability in comparison with those of the cells derived from patients who did not receive AWT. The evolution of patient satisfaction during the time for each group of treatment was investigated, and cellular treatments show the best maintenance of patient satisfaction over time. Conclusions: Dermgraft and AWT approaches resulted in the highest patient satisfaction for the non-surgical correction of the saddle nose deformity.

Introduction: Primary intraosseus orbital hemangiomas are rare vascular anomalies, of which only 23 cases have been previously reported in the literature. We here describe a further two cases. Materials and Methods: An anterior approach was used to remove a mass located in the inferior orbital rim in one case, and in the orbital floor in the other. Results: Good restoration of the orbital walls with no signs of recurrence. Discussion: Intraosseous hemangiomas of the orbit are usually located anteriorly, and can be removed by anterior surgical approaches. The main surgical problem is due to the removal of the involved areas of the orbital walls because resection without reconstruction may cause functional impairments and secondary deformities that are more damaging for the patient than the tumour itself. In order to avoid defects, the integrity of the orbital walls must be immediately restored by means of autologous bone or alloplastic grafts.
