Objective: To evaluate the incidence of infection and extrusion of porous high-density polyethylene (pHDPE) and expanded polytetrafluoroethylene (ePTFE) implants used in rhinoplasty at a high-volume, academic facial plastic surgery practice.
Methods: A total of 662 rhinoplasty procedures performed by 3 faculty surgeons from 1999 to 2008 were retrospectively reviewed. Patient demographics, medical comorbidities, operative details, and postoperative course findings were collected from patient records.
Results: The incidence of postoperative infection was 2.8% (19 of 662 patients). In each case of infection, alloplastic material had been used. Infections occurred in 1 in 5 rhinoplasty procedures in which pHDPE implants were used. In patients in whom ePTFE was used alone, the infection rate was 5.3%. Exposure developed in 12% of patients in whom an alloplast was used during surgery. Factors notably not associated with infection on bivariate analysis included sex, surgeon, purpose of procedure (functional vs cosmetic), current tobacco use, or history of cocaine use (P > .05 for all).
Conclusions: To our knowledge, this study represents the largest evaluation of the use of pHDPE implants in rhinoplasty to date. Our findings are in contrast to those of previous studies regarding the use of pHDPE in rhinoplasty and parallel to those regarding the use of ePTFE. Caution is strongly recommended when considering the use of pHDPE in rhinoplasty.

Why Does an "Avatar Nose" Appear After Dermal Filler Injection? Insights From a Cadaveric Study on the Nasofrontal Ligament.

Background: Nonsurgical rhinoplasty (NSR) with dermal fillers has gained popularity because of its immediate and visible results, minimal downtime, and long-lasting effects. However, complications such as filler migration can lead to the development of the "Avatar nose," a condition where the nose appears unnaturally wide and bulbous in the nasion area, disrupting facial harmony. This phenomenon is often exacerbated by the presence of a taut nasofrontal ligament, which tethers the periosteum to the dermal layer and influences nasal contour.

Background: The purpose of this study was to analysis the nostril symmetry and nasal stability following secondary rhinoplasty performed with either nasal septal cartilage implantation (G1) or simple alar cartilage suspension and internal fixation (G2) in patients with unilateral secondary cleft nasal deformity.
Methods: Nostril and alar symmetry were analyzed retrospectively in 13 consecutive patients in G1 and 17 in G2. Assessment of three indexes was first performed using photogrammetric measurements of photographs at pre-operation(T1), 7 days after repair (T2), and at least 6 months after repair (T3).

Background: The risk/benefit ratio of operating on the cleft nasal deformity in the period of mixed dentition remains debated. This study characterizes our 18-year experience with intermediate cleft rhinoplasties to add data and nuance to the discussion.
Methods: We performed a retrospective cohort study of patients who underwent intermediate cleft rhinoplasty from 2006 to 2023.
Extrusion of High-density Porous Polyethylene Implants in the Nose.

Few alloplastic implant materials have been successfully used in nasal reconstruction. The high-density porous polyethylene (HDPE) implant is the most widely accepted alloplastic material for reconstructing the nasal structure. Some authors suggest that the problems associated with using grafts and biocompatible materials are often due to errors on the part of the surgeon or the technique used.

Article Synopsis
- Autologous bone grafts, particularly from the proximal tibia, are examined as a viable option for maxillofacial surgeries, offering low donor site morbidity and the advantage of local anaesthesia options.
- In a study of 21 tibia grafts, 57% were used for alveolar ridge reconstruction and 43% for rhinoplasty, with minor complications reported at donor and recipient sites.
- Overall, the findings suggest that proximal tibia grafts are effective for these procedures, with a high implant survival rate of 86.7% over median follow-up of 40.5 months.
