Abstract
OBJECTIVE To assess the efficacy of newly designed butterfly splint with special technique for middle turbinate stabilization in preventing adhesion following bilateral endoscopic sinus surgery (ESS) for chronic rhinosinusitis with nasal polyps (CRSwNP). STUDY DESIGN Prospective, double-blind, randomized controlled. SETTING University hospitals. METHODS Following ESS, in cases of traumatized and/or unstable middle turbinates, newly designed butterfly plastic splint was randomly inserted in the middle meatus of one nasal side, while no splint was inserted in the other (control). Patients were followed up on after 1 week, 1 month, and 6 months. Endoscopic examination and a visual analog scale were used to evaluate each side of the nasal cavity for adhesion, crusting, pus, pain, nasal obstruction, and nasal discharge. RESULTS Thirty patients (60 nasal sides) were included. For all investigated parameters, there was no significant difference between the splinted and non-splinted sides at the first week visit. Adhesion was found significantly less in the splinted sides (3%) than the non-splinted sides (27%) after 1 month (P = 0.038). The adhesion rate in the splinted sides remained 3% at the 3 month follow-up visit, however, in the non-splinted sides, the rate increased up to 30% (P = 0.007). Throughout the follow-up visits, all other investigated parameters remained statistically insignificant between both sides. CONCLUSIONS The newly designed butterfly plastic splints to avoid middle turbinate adhesion is safe and effective in both reducing middle meatal adhesion with low complication rate in CRSwNP patients undergoing ESS and middle turbinate stabilization in its intermediate position.

Cureus 2024; 16:e51732.

Abstract
PURPOSE The purpose of this study was to evaluate the safety and tolerability of VELNEZ (Datt Mediproducts Pvt. Ltd., New Delhi, India) as a space-occupying dressing for controlling hemorrhage after ear surgery. METHOD A total of 21 patients were included in an open-label, interventional, single-arm post-marketing surveillance study to investigate the safety and efficacy of the VELNEZ ear pack. The patients were questioned for collecting data related to the subject's safety and comfort, adverse events, site assessment, and otoscopic examination from discharge day to last follow-up (eight follow-up visits) at regular intervals. The standardized questionnaires for VELNEZ tolerability (pain/pressure effect, infection, and general satisfaction) were used after ear surgery. RESULTS The average hemorrhage control time was 1.08 ± 0.16 minutes. None of the subjects reported moderate pain at any of the study visits following surgery. This biodegradable ear pack had an average disintegration time of 25.4 days in the ear cavity. No postoperative adverse events or serious adverse events were observed. CONCLUSION VELNEZ is safe and effective as a space-occupying dressing pack after ear surgery and is well-tolerated by patients.

Multimodal additive manufacturing of biomimetic tympanic membrane replacements with near tissue-like acousto-mechanical and biological properties. Acta Biomater 2023; 170:124-141. [PMID: 37696412 DOI: 10.1016/j.actbio.2023.09.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 08/08/2023] [Accepted: 09/05/2023] [Indexed: 09/13/2023]
Abstract
The three additive manufacturing techniques fused deposition modeling, gel plotting and melt electrowriting were combined to develop a mimicry of the tympanic membrane (TM) to tackle large TM perforations caused by chronic otitis media. The mimicry of the collagen fiber orientation of the TM was accompanied by a study of multiple funnel-shaped mimics of the TM morphology, resulting in mechanical and acoustic properties similar to those of the eardrum. For the different 3D printing techniques used, the process parameters were optimized to allow reasonable microfiber arrangements within the melt electrowriting setup. Interestingly, the fiber pattern was less important for the acousto-mechanical properties than the overall morphology. Furthermore, the behavior of keratinocytes and fibroblasts is crucial for the repair of the TM, and an in vitro study showed a high biocompatibility of both primary cell types while mimicking the respective cell layers of the TM. A simulation of the in vivo ingrowth of both cell types resulted in a cell growth orientation similar to the original collagen fiber orientation of the TM. Overall, the combined approach showed all the necessary parameters to support the growth of a neo-epithelial layer with a similar structure and morphology to the original membrane. It therefore offers a suitable alternative to autologous materials for the treatment of chronic otitis media. STATEMENT OF SIGNIFICANCE: Millions of people worldwide suffer from chronic middle ear infections. Although the tympanic membrane (TM) can be reconstructed with autologous materials, the grafts used for this purpose require extensive manual preparation during surgery. This affects not only the hearing ability but also the stability of the reconstructed TM, especially in the case of full TM reconstruction. The synthetic alternative presented here mimicked not only the fibrous structure of the TM but also its morphology, resulting in similar acousto-mechanical properties. Furthermore, its high biocompatibility supported the migration of keratinocytes and fibroblasts to form a neo-epithelial layer. Overall, this completely new TM replacement was achieved by combining three different additive manufacturing processes.

Effect of middle ear gelfoam on hearing and healing process after tympanoplasty: A prospective randomized case-control study. Am J Otolaryngol 2021; 42:102767. [PMID: 33166858 DOI: 10.1016/j.amjoto.2020.102767] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2020] [Accepted: 10/13/2020] [Indexed: 11/22/2022]
Abstract
PURPOSE This prospective randomized case-control study was performed to compare the surgical outcomes of our swing-door overlay tympanoplasty with or without absorbable gelatine sponge (AGS, gelfoam) packing in the middle ear cavity, according to the surgical procedure. METHODS Fifty-seven patients who underwent swing-door overlay tympanoplasty by a single surgeon were enrolled in the study. The data of 30 patients of the gelfoam-packing group (GPG) and 27 patients of the non-gelfoam-packing group (NGPG) were prospectively collected and compared. RESULTS Closure of the tympanic membrane was found to be successful in all patients at postoperative 3 months evaluation. NGPG showed a statistically better healing process compared to GPG; earlier epithelialization and less fascia edema in NGPG than in GPG (P < 0.05). The air-bone gap (ABG) measured at postoperative 1 and 2 months was smaller in NGPG than GPG, although there were no statistical differences. CONCLUSION This study revealed earlier healing process and faster recovery of ABG in NGPG, thereby indicating that the gelfoam in the middle ear may interfere with both hearing recovery and the healing process of neodrum.
