The ideal technique nasal tip surgery for Asians, understanding best technique, and post-operative improvement: Systematic review/meta-analysis.

Introduction: Asian nose is characterized by thick skin, abundant soft tissue, and weak cartilage framework, resulting in under-projection of the nasal dorsum and tip. Anatomical knowledge consideration is needed to achieve an ideal and natural-looking Asian nasal tip. Various nasal tip surgery techniques for Asian nose have been introduced recently. However, a comparison of techniques and postsurgical results has not yet been undertaken. Objective: This systematic review aims to highlight the basic understanding of nasal tip dynamics aesthetic Asian nose and analyze related studies in search for the best technique and post-operative improvement for Asian tip-plasty. Method: Two independent reviewers conducted a comprehensive database search from four major medical databases (PubMed, Scopus, EBSCOhost, and EMBASE). Methodology quality and risk of bias in each study were assessed with the Risk of Bias In Non-randomized Studies - of Interventions (ROBINS-I tools). Result: The initial literature search (May-July 2023) yielded 53 articles, of which 26 were removed (duplicated). The title and abstract screening reduced the count to 6 articles, and two were excluded for specific reasons. Finally, four articles were included in the systematic review and proceeded to methodological quality check and risk of bias assessment. Conclusion: New techniques such as combining spreader graft, septal extension graft, and columellar strut graft for Asian tip-plasty show promising effect after surgery. Increasing nasal length, projecting the tip, and strengthening the nasal tip framework become key points for Asian tip-plasty.

The utilization of three-dimensional imaging and three-dimensional-printed model in autologous microtia reconstruction.

Background: The use of three-dimensional (3D) technology helps surgeons in performing autologous microtia reconstruction due to more accurate measurements and a better precision template model. However, the technical aspects of using a 3D imaging and 3D-printed model and the difference in outcomes postoperatively remain poorly reviewed. Purpose: This systematic review aimed to provide the current evidence of the benefit and technical aspects of using 3D technology in autologous microtia reconstruction. Method: A systematic literature search was conducted across multiple databases: Medline, Embase, Google Scholar, and Central until June 2022. Studies that evaluated the use of 3D imaging or 3D-printed models for autogenous microtia reconstruction were selected. The quality of the included studies was also assessed with respect to the study design. Result: A systematic literature search yielded 17 articles with a combination of observational and case report studies. Overall, 3D imaging showed a precise measurement for preoperative costal cartilage assessment. Compared to the 2D template, the utilization of a 3D-printed template provided a higher similarity rate relative to the unaffected ear, higher patient and surgeon satisfaction, and lower surgical time. Most 3D templates were fabricated using polylactic acid material on fused deposition modelling printers. The template costs were ranging from $1 to $4.5 depending on the material used. Conclusion: 3D imaging and 3D-printed templates could improve the outcome of autologous microtia reconstruction. However, the quality of the existing evidence remains low due to the heterogeneity of the reported outcomes. Further studies with more adequate comparability and defined outcomes are still required.

Incidence and Associated Factors of SARS-CoV-2 Infection Post-mRNA-1273 Booster Vaccination in Health-Care Workers.

The COVID-19 pandemic has caused significant morbidity and mortality worldwide, especially among health-care workers. One of the most important preventive measures is vaccination. This study examined factors associated with the incidence rate of SARS-CoV-2 infection after mRNA-1273 booster vaccination (preceded by the CoronaVac primary vaccination) and the antibody profile of health-care workers at one of the tertiary hospitals in Indonesia. This was a combined retrospective cohort and cross-sectional study. Three hundred health-care workers who were given the mRNA-1273 booster vaccine a minimum of 5 months prior to this study were randomly selected. Participants were then interviewed about their history of COVID-19 vaccination, history of SARS-CoV-2 infection, and comorbidities. Blood samples were taken to assess IgG sRBD antibody levels. The median antibody level was found to be 659 BAU/mL (min 37 BAU/mL, max 5680 BAU/mL, QIR 822 BAU/mL) after the booster, and this was not related to age, sex, comorbidities, or adverse events following immunization (AEFI) after the booster. SARS-CoV-2 infection after the booster was correlated with higher antibody levels. In sum, 56 participants (18.6%) experienced SARS-CoV-2 infection after the mRNA-1273 booster vaccination within 5 months. Incidence per person per month was 3.2%. Age, sex, diabetes mellitus type 2, hypertension, obesity, and post-booster AEFI were not related to COVID-19 incidence after the booster. History of SARS-CoV-2 infection before the booster vaccination was significantly associated with a reduced risk of SARS-CoV-2 infection after booster vaccination, with a relative risk (RR) of 0.21 (95% CI 0.09-0.45, p < 0.001).

Versatile grafting at the nasal tip.

Placing cartilage graft at the nasal tip is the most frequent technique to achieve proper tip projection and a well-balanced nose. The graft functions to support the nasal tip though reconstruction of the tripod concept legs and add greater definition to the tip. Tip grafts can be broadly classified into two categories: those that are used as mechanical nasal tip support, and those that are used for contouring or enchantment of nasal tip projection. This classification offers guidance to select the type of tip graft needed of overcome the present anatomy deformity.

Current advances in sinus preservation for the management of frontal sinus fractures.

PURPOSE OF REVIEW: This review summarizes the current advances in sinus preservation techniques with endoscopic sinus surgery for the well tolerated and effective management of frontal sinus fractures. RECENT FINDINGS: Advances in computed tomography (CT) imaging can now reproduce higher quality reformatted images, creating excellent diagnostic coronal, axial, and sagittal image views that provide a better evaluation of the frontal sinus outflow tracts (FSOTs). The FSOTs are pivotal in determining which technique is used in the management of frontal sinus fractures. Several recent studies have proposed sinus preservation protocols using endoscopic management of the frontal outflow tract as a viable alternative to frontal sinus obliteration. Among those protocols, extended endoscopic sinus frontal surgery with reconstruction of the frontal outflow tracts has been demonstrated to be well tolerated and effective. It can be used in conjunction with frontal sinus trephinations as well as to treat complications. SUMMARY: Modified treatment protocols have been developed based on thorough clinical examination and CT imaging in an attempt to provide a practical and safe protocol for the management of frontal sinus injuries. Conservative care and sinus preservation with or without endoscopic surgery can be done in selected cases with good result. The importance of preserving the frontal sinus is gaining acceptance in the evidence-based literature.
