RESUMO
OBJECTIVE: Providing lasting cosmetic and functional results for patients with saddle nose deformity with allograft. METHODS: This report describes experience with using a of freeze-dried allograft bone allograft in 58 patients who underwent dorsal augmentation over 5-year period (2018-2023). Thirty-eight patients had saddle-shaped deformity of the nose, and 16 patients had post-traumatic cases with saddle nose deformities. All patients underwent a clinical examination using computed tomography. Before surgery using a 3D model, the graft was contoured according to the shape of the nasal defect. The grafts were installed using a closed approach and were placed under the periosteum of the bone. Using lateral photographs, anthropometric measurements of the nose were taken before and after surgery to assess aesthetic outcome after surgery. To assess the results of aesthetic rhinoplasty (UQ), the Portuguese version of the Utrecht Questionnaire was used, which contains a visual analogue scale (VAS) on a 5-point Likert scale. RESULTS: A total of 56 patients were satisfied with the results of the surgical procedure. No complications or major graft resorption was observed. An analysis comparing preoperative and 1-year follow-up data using 3D scanning showed a significant increase in dorsal height without dorsal expansion. After rhinoplasty, the mean visual analog scale (VAS) aesthetic score improved significant from 2.3 preoperatively, 3 months postoperatively 8.4, and 8.9 1 year postoperatively. CONCLUSION: The use of freeze-dried allograft bone is a useful method of dorsal augmentation in rhinoplasty without donor site complications.

RESUMO
OBJECTIVES: The objective of this study is to minimize gingival display by surgical repositioning of the upper lip and to suggest this technique as an alternative treatment modality to orthognatic surgery for treatment of excessive gingival display. MATERIALS AND METHODS: Forty-eight patients were selected with gingival display of more than 2 mm during maximal smiling. All patients underwent surgical repositioning of the upper lip, aimed at limiting elevator muscle activity to treat excessive gum exposure. Patients were regathered in 1 week for the follow-up postoperative symptoms according to VAS scale to evaluate pain and swelling. Reference values were given to patients. RESULTS: The study has indicated good results and stability especially to patients with skeletal class I classification along with medium and thick biotype of attached gingiva without hypermobile upper lip. CONCLUSION: Surgical repositioning of the upper lip is an effective way to improve a patient's gingival smile caused by degree I and II VME in combination with HUL as an alternative treatment modality to orthognathic surgery. This method is less invasive and cost-effective, causes minimal postoperative complications, and provides faster recovery. CLINICAL RELEVANCE: Excessive gingival display (EGD) with various etiologies requires several proper treatment modalities. The proposed modified method of lip repositioning to reduce the degree of gingival display is less aggressive, reliable, and causes fewer postoperative complications compared to orthognathic surgery.
