Algorithm for the Treatment of Tip Malformation Combining a Clinical Qualitative Assessment and Specific Closed-Rhinoplasty Techniques Based on Retrospective Analysis of Pellegrini's Fellows 40 Years' Experience.

BACKGROUND: The aesthetic importance of nasal tip and the complexity of its surgical correction make the surgery of this area one of the most fascinating facial surgical procedures. Despite description of different sculpturing techniques to correct nasal tip defects, this surgery remains one of the most discussed and challenging aesthetic procedures. OBJECTIVES: The objective of this study was to define an algorithm of treatment for nasal tip surgery based on 40-year experience on Caucasian patients evaluated by our proposed clinical qualitative assessment, who were treated by closed rhinoplasty. METHODS: We retrospectively reviewed 19,643 Caucasian patients (15,266 females and 4,377 males) who underwent primary closed rhinoplasty from 1979 to 2019 due to different tip defects. The patients were evaluated by volume projection rotation (VPR) assessment. The surgical indications options, long-term aesthetic results and complications were analysed. RESULTS: 22% patients with minimal nasal defects were treated by non-delivery approach and 78% patients with important tip malformation by delivery approach. In all cases, the surgery was performed to reduce tip volume and modify tip projection and rotation based on the specific nasal defects. 67% patients, who needed important reduction of tip projection, were treated by tip-interrupting techniques. 88.7% patients declared full satisfaction after surgery, and only 12.3% needed a requiring minor revision surgery during the 20 years follow-up. CONCLUSION: The proposed algorithm may be a useful tool to plan surgery. The use of an adequate technique depending on the evaluation of volume, projection and rotation may guarantee higher patients satisfaction and a stable long-term aesthetic result.

Histology and Long-term Clinical Outcome of Crushed Cartilage with Double-layer Gelatin Sponge Membrane for Dorsum Refinement in Primary Rhinoplasty.

This article demonstrates the ability to use autologous crushed cartilage grafts in rhinoplasty with rapid recovery and optimal nasal functionality without any tissue damage and allows its rapid rejuvenation. Eligible patients underwent primary rhinoplasty using autologous crushed cartilage graft followed by microscopy imaging of the grafted tissue after recovery. Tissue and cytological analysis using optical microscopy, transmission electronic microscopy (TEM), and scanning electronic microscopy (SEM) showed complete viability of chondrocytes, formation of new collagen fibers, neo-perichondrium, neo-angiogenesis, and exhibiting optimal aesthetic outcome. The surgical approach is easy to perform, feasible, and less time-consuming, with excellent tissue rejuvenation and rapid recovery.

Variations of the profile of the nose of the upper lip.

BACKGROUND: The aim of this study is to analyze the path needed to achieve a good aesthetic and functional result in patients treated with orthognathic surgery. METHODS: Seventy-three patients with only III class malocclusion were treated with sagittal split ramus osteotomy and with Le Fort I in only one piece. Through the analysis of anatomical cephalometric tracings, changes in the skeletal base, upper incisor and nose's shape were evaluated. The statistical analysis measurements were calculated for each length and for each angle at T0 (preoperative value) and at T1 (postoperative value). RESULTS: A significant statistical correlation was found mainly between forward movement of the upper maxilla and the outline of the nose, the nasal projection, and the naso-labial angle (NLA). The upper incisor in movements of verticality and inclination did not show any significant correlations with modifications of the NLA. CONCLUSIONS: A significant correlation can be seen between the forward movements of the upper maxilla with the outline of the nose, the nasal projection and the Naso-Labial Angle.

Septal extension graft in "closed" revision rhinoplasty: A simplified technique.

BACKGROUND: The septal extension graft (SEG) is widely used in secondary rhinoplasty for correction of a short nose with loss of tip support and projection, columellar retraction, and hyper-rotated tip secondary to an overresection of the caudal septum. Although SEG precise fixation can be relatively easy in the external approach, the difficulties of SEG placement in "closed" rhinoplasty can be discouraging. OBJECTIVE: To describe an easy surgical technique for SEG placement in endonasal revision rhinoplasty and to analyze the aesthetic results of the procedure. METHODS: Thirty-eight patients were submitted to an endonasal approach revision rhinoplasty with endonasal placement of SEG for the correction of a short nose with a hypoprojected and hyper-rotated nasal tip. Pre- and postoperative nasal length, tip projection, and tip rotation (nasolabial and lobulocolumellar angles) were measured for each patient. RESULTS: An increase (mean ± standard deviation) of nasal length by 15.02 ± 3.91% and an augmentation of tip projection by 11.34 ± 2.26% were noticed after surgery with respect to preoperative conditions. A significant (p < 0.001) decrease in the columellar-labial angle was recorded on postoperative (91.23 ± 3.85°) examination with respect to preoperative (99.81 ± 6.49°) conditions. A decrease (p < 0.001) in the columellar-lobular angle was noted on postoperative assessment (34.02 ± 5.28°) with respect to preoperative examination (50.02 ± 0.36°). No relevant postoperative complication was recorded. CONCLUSION: The "endonasal" approach described for SEG placement was an easy and reliable procedure to treat a short nose with loss of tip support and projection, columellar retraction, and hyper-rotated tip, especially in revision surgery. The advantages of our technique over previously described approaches were reported.

Chin Microgenia: A Clinical Comparative Study.

BACKGROUND: The aesthetic relevance of the chin and its relatively simple correction through different approaches make genioplasty one of the most performed aesthetic procedures of the face. Sliding genioplasty is extremely rewarding, particularly when performed as an adjunction to rhinoplasty, rhytidectomy, or jaw surgery. In the scientific literature, many different surgical techniques are described, but the biological implications and the economical impact can shape the surgeon's decision on which can be the best treatment: surgical correction with osteotomy, chin implants, or with fillers. OBJECTIVE: The authors propose a decision making protocol for correcting chin microgenia based on a revision of 345 treated cases. METHODS: A retrospective review of 345 cases of chin microgenia was undertaken to understand the proper preoperative assessment and therapeutic planning. A total of 135 patients were treated with surgical sliding genioplasty (group A): 60 patients (group B) have been grafted with alloplastic implants and the remaining 150 patients (group C) with hyaluronic acid. We recorded clinical indications, complications, and long-term aesthetic results at 3-year follow-up. RESULTS: The analysis of the results based on the entity of the chin's sagittal defect, the chin soft-tissue thickness, the patient's age, and self-judgment allows for simplified treatment planning for sagittal chin deformities showing a greater predictability and a more stable long-term aesthetic result regarding sliding genioplasty compared to alloplastic implant placement and fillers. CONCLUSIONS: Our proposal for a simple and versatile protocol of chin microgenia aims to simplify the therapeutic indications for a predictable and a stable long-term aesthetic result.

Surgical treatment of unilateral condylar hyperplasia with piezosurgery.

INTRODUCTION: Unilateral condylar hyperplasia (UCH) is a disorder of unknown etiology mainly seen in growing patients, which results in facial asymmetry. High condylectomy alone or in association with orthognathic surgery can improve the occlusion and the facial aesthetics. MATERIALS AND METHODS: Between 2005 and 2012, a total of 5 patients underwent high condylectomy for UCH using a piezoelectric cutting device. All patients were treated postoperatively with functional rehabilitation. RESULTS: The long-term follow-up showed that all patients had a satisfactory temporomandibular joint articular function associated with stable occlusion without any recurrence of further condylar growth. CONCLUSIONS: High condylectomy in the surgical treatment of unilateral UCH seems to be the procedure of choice in growing patients. The use of a piezoelectric cutting device allows a safe and less invasive high condylectomy.
