Aesthetic and Functional Outcomes of Open Carpal Tunnel Release and Thread Carpal Tunnel Release: A Randomized Clinical Trial.

Background and Objectives Surgical techniques for carpal tunnel release (CTR) have gradually become less invasive. No substantial evidence supports replacing the open carpal tunnel release (OCTR) with novel minimally invasive approaches. Thread carpal tunnel release (TCTR) is a new minimally invasive CTR method associated with promising results. This study aimed to compare the aesthetic and functional outcomes of OCTR with TCTR. Materials and Methods This study was a randomized clinical trial conducted in a hospital in Tehran, Iran, in 2022. Patients were randomized to OCTR and TCTR groups through simple randomization. Data such as demographics, nerve conduction study, electromyography, pain, and sensory evaluation by monofilament test were recorded in patients at baseline and after 3 months. Aesthetic evaluation was conducted by assessing the scar length and patients' satisfaction 3 months after the surgery. Results Twenty patients (10 in each group) entered the final analysis. Nerve conduction study, electromyography, and sensory evaluation were similar between groups 3 months after the operation. The TCTR group had lower postsurgical pain ( p < 0.001) and lower scar length ( p < 0.001) compared to the OCTR group. Overall satisfaction was not statistically different between TCTR and OCTR. Conclusion The TCTR method is safe in patients with CTS, and its efficacy is similar to OCTR. It can be a good alternative for OCTR, with a better aesthetic outcome.

Evaluating the Effect of Tranexamic Acid Local Injection on the Intraoperative Bleeding Amount and the Postoperative Edema and Ecchymosis in Primary Rhinoplasty Patients: A Randomized Clinical Trial.

BACKGROUND AND AIMS: The purpose of this study was assessing the effect of local injection of tranexamic acid (TXA) on the amount of bleeding during the primary rhinoplasty and edema and ecchymosis following the surgery. METHODS: In this randomized clinical trial, 50 patients applying for primary rhinoplasty were divided into two groups of intervention and observation. In the intervention group, 10 mg/kg of TXA was injected locally to the operation field. In the observation group, no medicine was injected. The same anesthesia technique was used during the operation for all the patients. Age, sex, blood pressure, bleeding amount during the operation, the amount of edema and ecchymosis on the first and seventh day after the surgery were noted. The data were analyzed by the SPSS software version 24 and using descriptive statistics of frequency and percentage of frequency and Fisher and Mann-Whitney's exact statistical tests. RESULTS: Our results showed that there was a significant difference between the amounts of bleeding during the surgery between two groups (P-value < 0.001). Also, the postoperative edema on the first and seventh day in intervention group was less than the observation group (P-value < 0.001). There were no complications during the surgery and in the follow-up of the patients. CONCLUSION: We revealed that local injection of TXA during the rhinoplasty procedure and decreased the intraoperative bleeding and postoperative ecchymosis and edema without any side effects and complications.

Practical Classification of Upper Lateral Cartilage in Middle Vault Asymmetry.

BACKGROUND: Middle vault asymmetry is a common reason for retained postoperative deviations. Although minor deformities can be camouflaged with cartilage, soft-tissue materials, or injectable fillers, comprehensive observation of upper lateral cartilage and subsequent topographic classification in major anatomical anomalies will help surgeons better plan their procedures to obtain better symmetry. METHODS: Photographs of 71 randomly selected primary open rhinoplasty patients were analyzed for anatomical presentation of their upper lateral cartilage. Photographs were taken before and after separation of upper lateral cartilage from the septum. Upper lateral cartilage was classified from class I to class V according to the width of the transverse subunits and curvature of the vertical subunits. RESULTS: The authors observed 142 upper lateral cartilages of 71 rhinoplasty patients. Upper lateral cartilage was classified as follows: class I, 53 cases; class II, three cases; class III, 40 cases; class IV, 36 cases; and class V, 10 cases. CONCLUSIONS: Upper lateral cartilage asymmetry is a common occurrence in rhinoplasty, and the upper lateral cartilage itself may be the source of nasal deviation. The middle vault requires special attention, and establishment of a classification system could enable surgeons to devise an effective plan for correction and prevention of retained postoperative nasal deviation.
