MATERIALS AND METHODS: All materials from our study are published in peer-reviewed journals. The review is PubMed generated. In our clinic, 20 patients with bilateral paralytic laryngeal stenosis underwent cold-plasma posterior arytenoidcordotomy with Coblator II. RESULTS: The analysis of the high-energy techniques currently applied in otorhinolaryngology shows the benefits of coblation due to the effect of lower temperatures on tissues. Patients subjectively reported improved breathing on day 10 with a closed coblation tracheostoma; after 3-6 months everyone underwent successful decannulation with plastic surgery of the cutaneous-tracheal fistula. Lately, the operated vocal fold was in the abduction position and the lumen of the glottis in the posterior third was 7-8 mm. Compensation of vocal function in the long-term postoperative period was achieved by patients due to long-term orthophonic training and the development of a vestibuloscapular phonation mechanism. CONCLUSION: The advantages of coblation are mainly minimal trauma to the surrounding tissues, convenient resection, the ability to perform complete hemostasis at one time, and easier postoperative period for the patient.

LINC00937 suppresses keloid fibroblast proliferation and extracellular matrix deposition by targeting the miR-28-5p/MC1R axis

Online ahead of print. ABSTRACT Long noncoding RNAs (lncRNAs) are the most recently discovered class of noncoding RNAs. LncRNAs play a crucial role in multiple disorders. However, the role and mechanism of action of lncRNAs in keloids remain unclear. Here, qRT-PCR and western blotting assays were performed to determine the expression of genes and proteins, respectively. MTT assays were carried out to measure the proliferation of keloid fibroblasts. In addition, a luciferase activity assay was conducted to investigate the relationships between LINC00937 and miR-28-5p and between miR-28-5p and MC1R. The results showed that LINC00937 and MC1R were decreased, whereas miR-28-5p was increased in keloid tissues. LINC00937 overexpression in keloid fibroblasts could repress the extracellular matrix (ECM) deposition and cell proliferation and promote MC1R expression. Moreover, high expression of miR-28-5p and low expression of LINC00937 were detected in keloid fibroblasts. We further showed that LINC00937 promoted MC1R expression by sponging miR-28-5p. Finally, our data indicated that LINC00937 inhibited the ECM deposition and proliferation of keloid fibroblasts by inhibiting miR-28-5p and facilitating MC1R expression. Overall, LINC00937 suppressed the ECM deposition and proliferation of keloid fibroblasts by acting as an miR-28-5p sponge and promoting MC1R expression. Our data suggested that LINC00937 is a potential target for keloid treatment. PMID:34486677 | DOI:10.14670/HH-18-372 View on the web Inoreader. Take back control of your news feed.

Cochlear implantation under local anesthesia in 117 cases: patients' subjective experience and outcomes

xlomafota13 shared this article with you from Inoreader Cochlear implantation under local anesthesia in 117 cases: patients' subjective experience and outcomes Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2021 Sep 6. doi: 10.1007/s00405-021-07061-4. Online ahead of print. ABSTRACT PURPOSE: To report the outcomes and the patients' subjective experience of cochlear implantation (CI) performed under local anesthesia (LA). To describe a new form of intraoperative cochlear monitoring based on the patients subjective sound perception during CI. METHODS: In this retrospective case-cohort study, 117 patients underwent CI under LA with (n = 58) or without conscious sedation (n = 59). Included were primarily elderly patients with elevated risks for general anesthesia and recently patients with residual hearing eligible for electro-acoustic stimulation (EAS) (n = 27), in whom hearing could be monitored during the electrode insertion. A 500 Hz test tone was presented and the patient reported of subjective changes in loudness, leading to a modification of the insertion. A questionnaire was sent to all patients in whi ch they assessed their subjective experience. RESULTS: All patients were successfully operated under LA without the need to intraoperatively convert to general anesthesia. 90% of the patients reported that the surgery was a positive experience. The vast majority, 90% of patients were satisfied with the overall treatment and with intraoperative pain management and 84% of the patients would opt for local anesthesia again. Cochlear monitoring by the patients' subjective sound perception enabled for atraumatic insertions as all EAS patients could hear the test tone up to the end of the surgery. CONCLUSIONS: CI under LA was well tolerated and recommended by the vast majority of patients. In addition, it offers the possibility to monitor the patients' hearing during the electrode insertion, which may help to prevent insertion trauma.
