“…The inflammation and edema observed with endoscopy in all VC during the first week after surgery occurred because whenever an implant is placed, an inflammatory reaction occurs in the surrounding tissue in the periphery of the prosthesis during the first hours or days after implantation and disappears over time. This is consistent with reports by de Souza et al [ 3 ], Zhang et al [ 26 ], and Ruijgrok et al [ 27 ], who have studied the use of different materials as implants. Moreover, the reduced inflammatory response observed in the VC that were implanted with LGPBP occurred because this is a biologically inert material, which, unlike the synthetics, is less porous, more flexible, and has more tissue-like characteristics; therefore, it produces less foreign body reaction, as described by other authors who have used different synthetic materials for medialization [ 3 , 5 , 6 ].…”

“…Medialization of paralyzed vocal cords (VC) by type I thyroplasty is a transcervical surgical procedure in which a prosthesis is implanted in the entire length of the vocal fold through a window made in the thyroid cartilage and placed into a small dissection sac within the paraglottic space to transfer the VC to the midline to improve glottic closure [ 1 – 3 ].…”

This study compared the use of lyophilized glutaraldehyde-preserved bovine pericardium (LGPBP), polytetrafluoroethylene (PTFE), polyethylene terephthalate (PET), and Teflon felt (TF) as implants for vocal cords (VC) medialization and aimed to assess the endoscopic, macroscopic, and microscopic VC changes after medialization in a canine model. In 18 mongrel dogs, the right VC were medialized with LGPBP and the left were implanted as follows: Group I (n = 6): LGPBP and PTFE; Group II (n = 6): LGPBP and PET; Group III (n = 6): LGPBP and TF. Surgical handling of the implants was compared. Three months after surgery, macroscopic and microscopic changes of VC and implants were evaluated. LGPBP offered the best surgical handling (p = 0.005, Kruskal-Wallis). TF implants showed extrusion (p = 0.005, Kruskal-Wallis) and severe inflammation. All VC formed fibrous capsules around the implants; the ones developed by LGPBP implants were thinner (p = 0.001, ANOVA, Tukey). VC implanted with synthetic materials showed eosinophilic infiltration (p = 0.01, Kruskal-Wallis). We concluded that the LGPBP could be used as an implant for VC medialization because it is biocompatible, easy to handle and remove during surgical procedures, and nonabsorbable or extrudable and produces an inflammatory reaction similar to PTFE and PET.

“…Besides all aforementioned usages, BNC is used (experimentally) as a scaffold in bone tissue engineering [121][122][123], cartilage regeneration [124], laryngeal medialization [125], as a patch for esophageal defect repair [126], and for closure of ventricular septal defects [127], among many others.…”

Nanocellulose as a natural source for groundbreaking applications in materials science: Today’s state

et al. 2018

View full text Add to dashboard Cite

Nanocelluloses are natural materials with at least one dimension in the nano-scale. They combine important cellulose properties with the features of nanomaterials and open new horizons for materials science and its applications. The field of nanocellulose materials is subdivided into three domains: biotechnologically produced bacterial nanocellulose hydrogels, mechanically delaminated cellulose nanofibers, and hydrolytically extracted cellulose nanocrystals. This review article describes today's state regarding the production, structural details, physicochemical properties, and innovative applications of these nanocelluloses. Promising technical applications including gels/foams, thickeners/stabilizers as well as reinforcing agents have been proposed and research from last five years indicates new potential for groundbreaking innovations in the areas of cosmetic products, wound dressings, drug carriers, medical implants, tissue engineering, food and composites. The current state of worldwide commercialization and the challenge of reducing nanocellulose production costs are also discussed.

“…12 It is worth mentioning that the 3D scaffolding and the grafted matrix were better in the regeneration of the epithelium 3 months after implantation. 12 In tissue engineering BNC is widely used in bone tissue engineering, [78][79][80] cartilage regeneration, 81 medicalization of the larynx, 82 repair of oesophageal defects 83 and many other applications. 12 Due to the fact that BNC has a high potential for use in tissue engineering one can expect that it will be used very widely in the future.…”

This review reports recent advances in the application of bacterial nanocellulose (BNC) in biomedical fields. BNC has attracted both academic and industrial attention as it shows interesting properties for both biomedical and cosmetic applications. Herein, the structure, properties and selected applications of BNC in the preparation of wound dressings and artificial skin are discussed in general, and detailed examples are also drawn from the scientific literature. In this review the most common applications are presented in detail together with issues related to regenerative medicine and biomedicine, skin tissue engineering, auricular cartilage reconstruction, bone regeneration and the treatment of traumatic tympanic membrane perforation. © 2019 Society of Chemical Industry
