Sutureless microvascular anastomoses could simplify the microvascular field, shortening operative time and improving the final outcome. The use of thermosensitive poloxamers (TP407) together with the application of cyanoacrylate as an alternative method for conventional sutures was well-documented for arteries, but not for veins. The purpose of our study was to prove the feasibility of this technique for venous anastomoses and compare it with the traditional hand-sewn technique on a rat model.
Twenty male Sprague-Dawley rats that weighed between 265 and 310g were used. In the sutureless group (SG), 20 left external jugular veins (LEJV) end-to-end anastomoses were performed using a T704 and cyanoacrylate glue. They were compared to 20 right external jugular veins (REJV) anastomoses sutured with conventional 10-0 stitches (control group - CG). Diameters of veins, anastomosis time, and patency rate at 15 days were reported. Foreign body reaction was assessed histologically.
The mean diameter of the LEJV was 0.94±0.1mm and 0.95±0.09mm for the REJV. The mean anastomosis time was 11.9±1.37min for the SG and 27.75±3.31min for the CG. In the latter group, the immediate patency rate was 95% and 90% at 15 days. For the SG group, 90% of the anastomoses were patent immediately and 85% at 15 days.
TP407 and cyanoacrylate could offer a fast and reliable technique for sutureless venous anastomoses. Before human application, effectiveness of this method remains to be confirmed in larger animals in a long-term follow-up.

Cadaveric studies suggest that a thick part of the distal interosseous membrane (DIOM), known as the distal oblique bundle (DOB), contributes to the distal radioulnar joint (DRUJ)'s stability. We hypothesized that the DIOM thickness, measured through magnetic resonance imaging (MRI), has a clinically significant association with DRUJ stability.
We retrospectively reviewed patients, from February 2018 to April 2019, who underwent wrist MRI examination with physical examination for DRUJ stability. Navitoclax We evaluated the correlation between their MRI findings (i.e., triangular fibrocartilage complex [TFCC] tears and presence of the DOB) and DRUJ instability.
Out of 85 patients with an average age of 42 years, 45 (53%) had foveal TFCC tears, 29 (34%) had a DOB, and 38 patients (45%) had clinical DRUJ instability. Patients with DRUJ instability had a significantly higher incidence of foveal TFCC tears (30/38, vs 15/47, p < 0.001), while DOB was absent (36/38 vs. 20/47, p < 0.001). Among 45 patients with foveal TFCC tears, only 1 out of 13 patients with a DOB had DRUJ instability, whereas 29 out of 32 patients without a DOB had DRUJ instability (p < 0.001). The odds ratio for DRUJ instability was 11.7 (95% CI 2.9-47.5, p=0.001) for foveal TFCC tear and 54.2 (95% CI 8.2-358.2, p < 0.001) for the absent DOB.
Clinical DRUJ instability was less common when the DOB is present in patients with foveal TFCC tears, which supports DOB's role as a secondary DRUJ stabilizer.

Safety of reconstructive microsurgery in elderly patients is still a topic of debate, because no conclusive evidence exists that provides indications and risk evaluation in elderly patients. The purpose of this study, which the Italian Society for Plastic, Reconstructive, and Aesthetic Surgery (SICPRE) has promoted, is to evaluate the safety and the complication risk of elective reconstructive microsurgery in elderly patients as well as to identify patient- or procedure-related risk factors. The secondary aim is to evaluate the predictive role for complications of the Geriatric 8 score (G8).
A total of 194 consecutive patients from 18 centers, aged 65 or older, who received an elective microsurgical flap between April 2018 and April 2019 were prospectively evaluated. Patient-related, treatment-related, and outcomes data were recorded and statistically analyzed through multiple-adjusted logistic regression models.
Our study showed an increased risk of complications and a longer hospitalization in patients aged ≥75 years with the American Society of Anesthesiologists (ASA) score ≥3 (or G8 score ≤11) as compared to patients >65 years of age and <75 years of age who undergo reconstruction with a microsurgical flap. Instead, flap survival did not significantly vary with age, but was associated only with ASA score ≥3 (or G8 score ≤11) and surgeries that last longer than 480 min; however, flap survival (92.3%) was slightly lower than that commonly reported for in the general population.
Reconstructive microsurgery in the elderly is generally safe. The ASA score is easier and quicker than the G8 score and equally useful for risk stratification.

Preservation rhinoplasty (PR) is considered to be an innovative approach with high patient satisfaction. However, little is known about its functional outcomes and radiological analyses.
In this prospective clinical study, 30 patients (20 female and 10 male patients, mean age 30.7 ±9.8 years) were operated on between 2017 and 2021. Radiological assessment was evaluated by cone beam computed tomography before surgery and at final follow-up. Patient assessment regarding their outcome was assessed at final follow-up using a validated questionnaire (rhinoplasty outcomes evaluation questionnaire=ROE).
After a mean follow-up of 8.4 ± 5 months (range=1 - 18 months), radiological analyses denoted an overall improved internal nasal valve (INV) angle after surgery (preoperative=20.77° ± 3.2° vs. postoperative=21.82° ± 5.7°, p=0.18). Those results are in accordance with an overall high patient satisfaction for both function and aesthetics (ROE score 18.4 ± 4.3).
Our study showed a preserved and widened INV angle after PR, along with high patient satisfaction.
