Aims: The aim of this study is to evaluate the effect of Positive End Expiratory Pressure (PEEP) on surgical field bleeding and its respiratory and hemodynamic consequences in rhinoplasty surgeries.
Materials And Methods: This single-blind clinical trial performed in Amir Al-Momenin university Hospital in 2018. Seventy cases of rhinoplasty surgery patients Enrolled and were randomized into two groups; intervention (PEEP = 5) and comparison group (PEEP = 0). Surgical field bleeding and arterial oxygen saturation pulmonary dynamics and hemodynamic parameters were evaluated during operation and in post anesthesia care unit. Data were analyzed by SPSS software using descriptive and analytical statistics.
Results: PEEP applying had no negative effect on surgical bleeding as well as surgeon satisfaction, heart rate and blood pressure were similar in two groups. Pulmonary dynamics and oxygenation were stable and within normal values in all cases. The mean peak airway pressure was 17.87 ± 2.24 in the PEEP group and 16.08 ± 3.37 in the ZEEP group (P = 0.029).
Conclusion: applying low level PEEP during anesthesia improved recovery oxygen saturation but had no negative effects on the patient`s hemodynamics, and did not aggravate bleeding and visual clarity.

Department of Plastic Surgery, Shanghai Phiskin Clinic.
Hyaluronic acid (HA) injection, traditionally used for non-surgical rhinoplasty, is often associated with adverse effects such as increased nasal dorsum width. This study introduces the linear stereoscopic stack volume enhancement (LSSVE) injection technique as a solution for patients with low-profile noses, aiming to improve the nasal dorsum dimension, prevent long-term nasal widening, and address related concerns. A retrospective analysis was conducted on the clinical registry data of patients treated at Shanghai Phiskin Clinic from December 2020 to June 2024, who received HA injections using the LSSVE technique.

Introduction: Non-surgical alternatives to rhinoplasty are gaining interest but, despite its popularity, research on the long-term psychological impact and post-rhinofiller patients' satisfaction is limited. This study evaluates patient-reported satisfaction and quality of life immediately after and 6 months post-non-surgical rhinoplasty using the FACE-Q questionnaire.
Patients And Methods: This prospective study was conducted from May 2023 to March 2024, involving 83 patients who underwent rhinofiller treatments for esthetic purposes.
