Abstract Background Upper arm liposuction mainly focuses on the posterolateral region, which may lead to a lack of harmony between the aspirated and unaspirated areas. In addition, the treatment effect of arm liposuction is often evaluated only by preoperative and postoperative photograph comparison and simple measurement; quantitative research on this topic is still lacking. Methods The multi-positional circumferential arm liposuction (MCAL) technique was proposed and applied to a total of 34 females in our hospital from 2017 to 2019. Three-dimensional data of 12 patients before the operation and after 2–3 months were collected and processed by 3D imaging, and the volume reduction rate was evaluated quantitatively. Results The MCAL method was successfully applied in the clinic, and its surgical effect was quantitatively studied. The mean follow-up time of 12 patients was (75.2 ±13.1) days, and the postoperative volume was significantly reduced. The postoperative volume of patients with type I, type II and type III decreased by (10.79 ±2.55)%, (17.25 ±3.02)% and (22.76 ±3.51)%, respectively. Conclusion Our new MCAL technique was successful, maximizing the esthetic results in upper limb contour refinements in the superficial fascial layer. The clinical efficacy of this proposed MCAL method was evaluated by CT and 3D digital technology, which provided further accuracy in demonstrating its effect on the shape of the arm.

PurposeTo report the long-term outcomes of Boston keratoprosthesis type I (B-KPro type I) implantation in the management of severe ocular surface disorders.MethodsRetrospective case series. Patients who underwent B-KPro type I implantation at the People’s Liberation Army General Hospital were enrolled between March 2011 and September 2019. Data regarding visual acuity (VA), B-KPro type I retention and postoperative complications were recorded and analysed.ResultsA total of 103 eyes of 100 patients who underwent B-KPro type I implantation were included. The main indications were chemical burn (59.2%), ocular trauma (25.2%), herpetic keratitis (11.7%) and autoimmune diseases (3.9%). The percentage of eyes with postoperative VA of 10/200 or better was 82.7% at 6 months, 82.8% at 12 months, 77.9% at 2 years, 72.4% at 3 years, 71.1% at 4 years, 69.4% at 5 years, 58.9% at 6 years, 56.8% at 7 years and 42.9% at 8 years. Preoperatively, 8.7% eyes were diagnosed with new-onset glaucoma. Retroprosthetic membrane formation occurred in 19.4% eye. Corneal melting occurred in 18.4% eyes. Sterile vitritis was diagnosed in 4.9% eyes and infectious endophthalmitis in 2.9% eyes. Retinal detachment occurred in 0.9% eyes.ConclusionsIn a Chinese patient group, B-KPro type I is a viable option for treating severe ocular surface disorders in eyes where conventional keratoplasty would have a poor prognosis, especially in patients with chemical and thermal burns. Improved visual outcomes and high retention rate can be achieved and maintained in most cases.

AimTo examine the mid-term visual and anatomical prognosis of patients who require reimplantation of a second Boston keratoprosthesis type 1 (B-KPro).MethodsRetrospective observational case series of 122 patients (141 eyes) who received a B-KPro at a single institution were reviewed. Eyes that underwent a second B-KPro were included in the study. Primary endpoints were B-KPro retention, final visual acuity 20/200 and loss of light perception. Secondary endpoints included the occurrence of postoperative complications.ResultsSeventeen eyes (12%) required a B-KPro reimplantation. Corneal melt was the most common indication for replacement (88%). Mean follow-up time after the second B-KPro was 4.4±2.1 years. The Kaplan-Meier analysis estimated the second B-KPro retention rate at 79% over 8 years. Retroprosthetic membrane (RPM, 53%) was the most common complication. Forty-one per cent of the eyes suffered from corneal melt following their second B-KPro. One year after the second B-KPro, 47% of the patients retained a vision 20/200. Seven eyes (41.2%) lost light perception, which was secondary to an inoperable retinal detachment in five cases. Four eyes (24%) developed phthisis following inoperable retinal detachment (n=3) or endophthalmitis (n=1).ConclusionB-KPro reimplantation is a potentially sight- and globe-saving procedure for eyes with B-KPro failure, but the prognosis is guarded. B-KPro reimplantation can salvage ambulatory vision in a third of patients while another third of patients progress to loss of light perception. RPM and retinal detachment were important obstacles to visual rehabilitation while recurrent corneal melt was responsible for most cases of anatomical failure.
