EAR, NOSE & THROAT JOURNAL 2024; 103:115S-119S. [PMID: 36219733 PMCID: PMC9554570 DOI: 10.1177/01455613221124773] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2022] [Revised: 08/12/2022] [Accepted: 08/28/2022] [Indexed: 11/15/2022] Open
Abstract
In this paper, we described technique of platelet rich plasma injection into the olfactory cleft in a 22-year-old female with 24-month post-COVID-19 anosmia. The technique starts with the blood extraction and the isolation of PRP through a 10-min centrifugation. The supernatant was injected in nasal regions after a local anesthesia through a 0° rigid optic. Several points of .2-.5 mL were performed in the nasal septum in regard of the head of the middle turbine and in the head of the middle turbine in both sides. The baseline threshold, discrimination, and identification scores were 1, 8, and 0, and the Olfactory Disorder Questionnaire score was 51, respectively. The injection of PRP in olfactory cleft was done without complication and mild pain. The patient perception of recovery of smell sense occurred at 3-week post-injection. From this time, the smell sense progressively improved to the 2-month consultation. At 2-month post-injection, the TDI scores reached 16, 16, and 16 (48), while the Olfactory Disorder Questionnaire was 73. The injection of PRP into the olfactory cleft appears to be a safe and easiness new approach that may improve the recovery of smell sense. Future controlled studies are needed.

[PMID: 37348245 DOI: 10.1016/j.amjoto.2023.103954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Revised: 06/05/2023] [Accepted: 06/05/2023] [Indexed: 06/24/2023]
Abstract
OBJECTIVE The objective of this study was to compare the healing outcome of fibroblast growth factor 2 (FGF2), ofloxacin ear drops (OFLX) and spontaneous healing for repairing large traumatic tympanic membrane (TM) perforations. MATERIAL AND METHODS A total of 75 traumatic large perforations with >1/4 of TM were randomly divided into FGF2 (n = 25), OFLX (n = 25), and spontaneous healing (n = 25) groups. The closure rates, closure times, and hearing gains were compared at 3 months. RESULTS At 2 weeks after treatment, the closure rate was 95.8 % in the FGF2 group, 96.0 % in the ofloxacin ear drops group, and 14.3 % in the spontaneous healing group (P < 0.01), respectively. At 3 months after treatment, the closure rate was 100 % in the FGF2 group, 100 % in the OFLX group, and 85.7 % in the spontaneous healing group, no among-group differences were significant (P > 0.05). The mean closure time was 9.69 ± 2.46 days in the FGF2 group, 9.45 ± 2.32 days in the OFLX group, and 30.94 ± 8.95 days in the spontaneous healing group (P < 0.01). The mean ABG was 10.37 ± 2.51 dB for the FGF2 group, 11.01 ± 1.31 dB for the OFLX group, and 10.86 ± 1.94 dB for the spontaneous healing group, no significant difference was found among three groups (P > 0.05). CONCLUSIONS This study suggested that both FGF2 and OFLX significantly shortened the mean closure time and improved the closure rate compared with spontaneous healing for repairing large traumatic perforations, while the healing outcome wasn't significantly different among FGF2 and OFLX groups.

Abstract
Background and Objectives: Platelet-rich fibrin (PRF) membrane plays an important role in cell proliferation and aids in healing. This study aimed to assess the safety and efficacy of the addition of PRF to the graft in tympanoplasty. Materials and Methods: A retrospective study was conducted involving 47 patients with chronic dry eardrum perforation, who were candidates for different types of tympanoplasty (type I-IV). The study took place in the ENT department, County Emergency Clinical Hospital of Cluj-Napoca. In group 1 (27 patients) tympanoplasty was performed with a cartilage graft, while in group 2 (20 patients) a cartilage graft was used with the addition of a PRF membrane. The PRF clot was extracted and transformed into a thin membrane. Postoperative evaluation included otoendoscopy and otomicroscopy at 1, 3, 6, and 12 months after surgery, as well as pure-tone audiometry at 12 months. Results: Postoperative follow-up at 1, 3, 6, and 12 months showed a higher rate of graft survival in the PRF group than in the non-PRF group. At the 12-month mark, a successful outcome was observed in 95.0% of patients in the PRF group, while the success rate in group 1 was 70.4% (p < 0.05). The postoperative hearing threshold value was statistically significantly lower in the group with PRF, compared to the non-PRF group, being 18.4 ± 10.4 dB and 27.6 ± 16.2 dB (p < 0.001), respectively. Although the postoperative air-bone gap value did not differ significantly between groups, there was a greater improvement in the PRF group (p < 0.7). The PRF was well tolerated, and the incisions healed perfectly. Conclusions: The PRF membrane increases the rate of autograft survival and is therefore an effective material for patients with chronic perforations of the tympanic membrane.

Abstract
Abstract
Background
Platelet-rich fibrin (PRF) which is considered a second-generation platelet-rich plasma having a high content of growth factors could be implied as a sealant and adjuvant to grafting materials during tympanoplasty operation. This work aimed to evaluate the role of autologous platelet-rich fibrin as an adjuvant in type 1 tympanoplasty (myringoplasty) for the closure of central tympanic membrane perforations. A prospective comparative study was conducted including one-hundred patients with chronic suppurative otitis media with dry central TM perforations. The patients were classified into two equal groups: group A (case group) was subjected to myringoplasty operation with the use of autologous PRF added to the temporalis fascia graft, and group B (control group) was subjected to myringoplasty operation using graft only without PRF. Both groups were assessed for successful closure of perforation defined as an intact eardrum, success in terms of hearing defined as closure of air-bone gap down to 10 dB or lesser, and hearing gain at 6 months postoperatively.
Results
At 6 months postoperatively, the success rate (graft taking) in group A (90%) was significantly higher than in group B (70%). Success in terms of air-bone gap closure (< 10 dB) revealed that in group A, success was achieved in 39 patients (78%), which was significantly higher than in group B 27 patients (54 %). Air-bone gap at 6 months postoperatively was more in the graft taken cases in the case group than in the control group with a significant difference. There was a nonsignificant correlation between graft uptake and either hemoglobin or platelet concentrations in both groups. In addition, there was a nonsignificant correlation between graft uptake and the size of the perforation in both groups.
Conclusion
Platelet-rich fibrin is a cheap, cost-effective, and completely autologous platelet concentrate with enriched growth factors. It improves the overall success rate of myringoplasty with no noticeable side effects.

Abstract
Extracellular vesicles are composed of fragments of exfoliated plasma membrane, organelles or nuclei and are released after cell activation, apoptosis or destruction. Platelet-derived extracellular vesicles are the most abundant type of extracellular vesicle in the blood of patients with traumatic brain injury. Accumulated laboratory and clinical evidence shows that platelet-derived extracellular vesicles play an important role in coagulopathy and inflammation after traumatic brain injury. This review discusses the recent progress of research on platelet-derived extracellular vesicles in coagulopathy and inflammation and the potential of platelet-derived extracellular vesicles as therapeutic targets for traumatic brain injury.

Abstract
OBJECTIVE This study aimed to explore the mechanisms of Hippophae fructus oil (HFO) in the treatment of tympanic membrane (TM) perforation through network pharmacology-based identification. METHODS The compounds and related targets of HFO were extracted from the TCMSP database, and disease information was obtained from the OMIM, GeneCards, PharmGkb, TTD, and DrugBank databases. A Venn diagram was generated to show the common targets of HFO and TM, and GO and KEGG analyses were performed to explore the potential biological processes and signaling pathways. The PPI network and core gene subnetwork were constructed using the STRING database and Cytoscape software. A molecular docking analysis was also conducted to simulate the combination of compounds and gene proteins. RESULTS A total of 33 compounds and their related targets were obtained from the TCMSP database. After screening the 393 TM-related targets, 21 compounds and 22 gene proteins were selected to establish the network diagram. GO and KEGG enrichment analyses revealed that HFO may promote TM healing by influencing cellular oxidative stress and related signaling pathways. A critical subnetwork was obtained by analyzing the PPI network with nine core genes: CASP3, MMP2, IL1B, TP53, EGFR, CXCL8, ESR1, PTGS2, and IL6. In addition, a molecular docking analysis revealed that quercetin strongly binds the core proteins. CONCLUSION According to the analysis, HFO can be utilized to repair perforations by influencing cellular oxidative stress. Quercetin is one of the active compounds that potentially plays an important role in TM regeneration by influencing 17 gene proteins.
