Simultaneous Orthognathic Surgery With Asian Double Eyelid Suture Blepharoplasty

What factors influence the cost of orthognathic surgery among patients in the US?

OBJECTIVE

The purpose of our study was to analyze what factors influence the cost of orthognathic surgery performed within the US.

STUDY DESIGN

This retrospective cohort study was completed using the Kids' Inpatient Database (KID) from 2000 to 2012 on all patients aged 14 to 20 years who had undergone orthognathic surgery. The predictor variables included patient and hospitalization characteristics. The primary outcome variable was hospital charge ($). Multivariate linear regression was conducted to determine independent predictors for increased/decreased hospital charge.

RESULTS

The final sample consisted of 14 191 patients (mean age, 17.4 ± 1.6 years; females, 59.2%). Each additional day in the hospital added $8123 in hospital charges (P < .01). Relative to mandibular osteotomy, maxillary osteotomy (+$5703, P < .01) and bimaxillary osteotomy (+$9419, P < .01) were each associated with increased hospital charges. Genioplasty (+$3499, P < .01), transfusion of packed cells (TPC) (+$11 719, P < .01), continuous invasive mechanical ventilation (CIMV) <96 hours (+$23 502, P < .01), and CIMV ≥96 hours (+$30 901, P < .01) were each associated with significantly increased hospital charges. Obstructive sleep apnea (OSA) added $6560 in hospital charges (P < .01).

CONCLUSIONS

Maxillary osteotomy and bimaxillary surgery were each associated with significantly increased charges relative to mandibular osteotomy. Concomitant genioplasty, TPC, CIMV, and OSA each significantly increased the charges. Each additional day to the length of stay significantly increased the charges.

Effect of Multichannel Convolutional Neural Network-Based Model on the Repair and Aesthetic Effect of Eye Plastic Surgery Patients

Objective

This study is aimed at exploring the impact of eye model based on multichannel convolutional neural network (CNN) on eye plastic surgery and aesthetic effect, thus formulating methods to improve the effect of eye plastic surgery.

Methods

A total of 64 patients who underwent pouch plastic surgery from January 2020 to March 2021 were selected as the research objects and were divided into observation group and control group by random number table method. The subjects in the observation group were evaluated by multichannel CNN-based eye model and doctors' experience, while those in the control group were evaluated by doctors' experience only, with 32 cases in both groups. Blepharoplasty, lower eyelid skin wrinkles, skin luster, and aesthetic scores were compared between the two groups.

Results

The similarity between the multichannel CNN model detected shape and the actual eye shape (98.78%) was considerably higher than that of the CNN model detected shape (78.65%) (P < 0.05). After treatment, the indexes of pouch degree, lower eyelid skin wrinkle, eyelid lacrimal sulcus, skin gloss, and aesthetic score in the observation group were better than those in the control group (P < 0.05). The incidence of complications in the observation group (13%) was considerably lower than that in the control group (28%) (P < 0.05).

Conclusion

The eye model based on the multichannel CNN model was helpful to improve the surgical repair and aesthetic effect of patients and can improve the occurrence of postoperative complications.
