Abstract

Background Rhinoplasty is one of the most common types of cosmetic surgery undertaken. In most rhinoplasty patients, an osteotomy is used to reshape the nasal pyramid. The most common complications following osteotomy are edema and ecchymosis. Edema and ecchymosis have a significant effect on a patients' satisfaction with surgery and their return to social activities. For this purpose, various methods have been used to reduce edema and ecchymosis, including intravenous injection of corticosteroids, cold compresses, and tranexamic acid. Objective To reduce edema and ecchymosis in rhinoplasty patients by administering a subcutaneous injection of dexamethasone and thereby prevent unwanted systemic side effects of corticosteroid treatments. Method We conduct a hospital-based nonrandomised study of rhinoplasty patients, with their informed consent treated over the course of one year. Dexamethasone was injected on one side of consenting patient's face immediately before surgery and the results were compared with the opposite side that was not injected. The face images of patients were taken on the front view on the first, third, seventh, and fourteenth days following the treatment. The grade of edema and ecchymosis encountered in each patient was determined by three ENT specialists. The degree of edema and ecchymosis was compared on the injected and noninjected sides and the findings were statistically analysed. The nonrandomised study considered 42 rhinoplasty patients. The mean age of patients was 27.9 years and their age ranged between 17 and 52 years. For 20 patients (47.6%), injection was performed on the right side, and for 22 patients (52.3%), injection was performed on the left side. Findings. The statistical analysis of patient outcomes reveals that a supraperiosteal injection of dexamethasone was not effective in reducing edema and ecchymosis after rhinoplasty.

Pretraining has recently greatly promoted the development of natural language processing (NLP)
We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
