There is no consensus about the ideal fixation methods and their effects on the condyle after the sagittal split ramus osteotomy (SSRO) procedure. The aim of this study was to compare the incidence, clinical presentation, and treatment of condylar sagging between different fixation methods following SSRO.
Patients who underwent double jaw surgery between 2007 and 2017 were evaluated retrospectively. Mandibular fixation was maintained using one of three different options a miniplate and a single bicortical screw, three bicortical screws, or a single bicortical screw. Some patients had malocclusion relapse in the early postoperative period due to condylar sagging, and needed reoperation. The reoperated condylar sagging patients were analysed statistically with respect to their fixation methods.
233 patients (134 females, 99 males) with a mean age of 23.3 years were enrolled in the study. The patients fixated with a single bicortical screw had lower revision surgery rates than those with three bicortical screws or with miniplate with a single bicortical screw (p=0.034 and p=0.032, respectively). These differences in central condylar sagging with a need for revision were statistically significant.
Although a miniplate and a single bicortical screw and three bicortical screws are widely used after SSRO, if the priority is to avoid sagging then it seems that a single screw should be preferred for osteosynthesis.

This study was aimed to compare the effectiveness of 3-0 knotless barbed suture (polydioxanone) with 4-0 polyglactin 910 (vicryl) in achieving wound closure after impacted mandibular third molar surgery.
Patients with bilateral mandibular third molar impaction of similar difficulty index enrolled in the split mouth study. Wound closure was done using 3-0 knotless suture (30×30cm) for the study group and 4-0 polyglactin 910 (vicryl) for the control group following extraction. Samples were allocated on the basis of simple randomization. The clinical outcome parameters that were measured were (1) time taken to achieve wound closure and hemostasis (2) postoperative mouth opening (3) swelling and (4) Pain. Data analysis involved descriptive statistics and paired t-tests (p<0.05). IBM SPSS software (v.20.0) was used.
A total of 25 patients participated in the study (14 males and 11 females) with the mean age of 25.6 years. The mean time taken for wound approximation was 2.45min and 4.1480min (p-0.026) for the study and control groups respectively. The difference in mouth opening (p-0.015), VAS score(p-0.24), and swelling (p-0.041) were statistically significant on the first post-operative day in the study group than the control group indicating reduction in pain (p<0.0001), swelling (p-0.033) and improvement in mouth opening (p<0.0001) on seventh post-operative day in the study group compared to the control group.
Knotless suture is an effective alternative to conventional sutures for intra oral wound closure as it reduces suturing time, facilitates effective wound closure and minimises knot related complications.

Ropeginterferon alpha-2b (Ropeg) is a novel pegylated interferon-alpha recently approved for the treatment of polycythemia vera (PV) in Europe. However, other than data from clinical trials, little is known about this agent in real world practice.
A compassionate use program employing Ropeg for treating patients with unmet medical need was initiated in Taiwan in 2017. Herein, we collected clinical data and assessed the safety as well as efficacy of Ropeg in nine patients treated in this program.
Collectively, among evaluable patients, both the molecular response and complete blood count remission rates were 62.5%. Most therapy-related side effects were mild, and there was no treatment discontinuation attributable to intolerable adverse events. The agent also showed efficacy in symptom amelioration and spleen size reduction. Although no specific patterns of cytokine level alteration could be identified, significantly attenuated plasma levels of inflammation markers were observed in one particular patient who happened to have normalized spleen size and most remarkable reduction in JAK2 mutant allele burden, indicating all-around improvement in every aspect of this case. Furthermore, plasma hepcidin levels increased in two-thirds of PV patients, illustrating the potential of Ropeg to restore normal regulation of erythropoiesis. Using RNA sequencing on pre- and post-treatment samples from one patient, we demonstrated altered expression of genes participating in IFN response, inflammation, apoptosis, and cellular differentiation.
Conclusively, observed signs of efficacy and safety in our real-world experience prove Ropeg as a promising option for the treatment of MPN.

The exact quantities of these ingredients in the recipe of recurrence, as well as possible interactions between them (e.g. the potentially increased fragility of myxoid pleomorphic adenomas; satellites or pseudopodia being cut off the tumor specimen during an extremely narrow extracapsular dissection) remain unclear. A thorough literature search did not reveal any proposed algorithms for the intraoperative management of a capsular tear. The aim of this short communication is to present our department's experience-based proposal for intraoperative measures in the case of macroscopic rupture and tumor spillage of a parotid gland pleomorphic adenoma.
