The literature still lacks a review regarding PROs applied for rhinoplasty. Thus, we performed a systematic review of the literature to identify PROMs that assess patient satisfaction and quality of life after rhinoplasty. The aim of our study was to identify existing questionnaires and to summarize their development, psychometric properties, and content. A multi-step search of the web-based PubMed database from the National Library of Medicine was performed to identify PROMs that are designed to evaluate satisfaction and quality of life following rhinoplasty. Each potential PROM was examined by three independent reviewers for adherence to inclusion/exclusion criteria. Questionnaires included in the analysis were appraised for their adherence to international guidelines for the development and validation of health outcome questionnaires, as outlined by the Scientific Advisory Committee of the Medical Outcome Trust and the U.S. Food and Drug Administration. Our search generated a total of 457 articles, 351 that were retrieved in the primary search, and 106 that were found in the references of the first set of articles. The process of development and validation of each of the included PROMs was examined. Only ten of these were identified as surgery-specific questionnaires about rhinoplasty. These were divided into three categories: (1) functional self-assessment (Nasal Surgical Questionnaire, Nasal Obstruction Symptoms Evaluation Scale, and Nasal Obstruction Septoplasty Effectiveness); (2) aesthetic self-assessment (Utrecht Questionnaire, FACE-Q rhinoplasty module, Glasgow Benefit Inventory); and (3) aesthetic and functional self-assessment (Rhinoplasty Outcomes Evaluation), Functional Rhinoplasty Outcome Inventory 17, RHINO Scale, and Evaluation of Aesthetic Rhinoplasty Scale).

Hyaluronic acid (HA), an essential component of the extracellular matrix, is an efficient space filler that maintains hydration, serves as a substrate for assembly of proteoglycans and is involved in wound healing. Although numerous pieces of evidence demonstrate beneficial effects in promoting wound healing in diabetes, a systemic approach has never been tested. We used an incisional wound healing model in genetically diabetic mice to test the effects of systemic injection of HA. Diabetic (n=56) and normoglycemic (n=56) mice were subjected to incision and randomized (8 groups of 7 animals each) to receive HA at different doses, 7.5, 15 and 30mg/kg/i.p., or vehicle (0.9% NaCl solution) for 12days. At the end of the experiment animals were sacrificed and skin wounds were excised for histological, biochemical and molecular analysis. Histology revealed that the most effective dose to improve wound repair and angiogenesis in diabetic mice was 30mg/kg. Furthermore HA injection (30mg/kg) improved the altered healing pattern in diabetic animals, increased skin remodeling proteins TGF-β and transglutaminase-II and restored the altered expression of cyclin B1/Cdc2 complex. Evaluation of skin from diabetic animals injected with HA revealed also an increase in HA content, suggesting that systemic injection may be able to restore the reduced intracellular HA pool of diabetic mice. Finally HA markedly improved skin mechanical properties. These promising results, if confirmed in a clinical setting, may improve the care and management of diabetic patients.
