The combining of therapeutic agents with electrospun nanofibers boosts their regeneration potential; therefore, Researchers have increasingly turned towards the development of electrospun nanofiber scaffolds to encapsulate or surface-adsorb biological payloads, such as cytokines, exosomes, peptides, nucleic acids, and enzymes. Due to their high surface-to-volume ratio, ease of manufacturing, and drug-loading capacity, electrospun nanofibers are hopeful in tissue engineering and scaffold fabrication. Electrospun multilayer scaffolds offer a promising construction for preserving the integrity and bioactivity of therapeutic factors while permitting the controlled and prolonged release of biomolecules into the environment.

Indian J Otolaryngol Head Neck Surg

December 2024

Clinical research development unit of Loghman Hakim Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Article Synopsis
  • The study assessed the condition of the opposite ear in patients undergoing surgery for chronic otitis media (COM), focusing on patients from three hospitals.
  • Out of 228 patients, a majority had non-cholesteatomatous perforations, with slightly fewer presenting with cholesteatoma, and about half had normal contralateral ears.
  • The research found that abnormal findings were more common in the PTP group than in the cholesteatoma group, and larger perforations were noted in the PTP group, but the size of perforation did not correlate with abnormality in the opposite ear.
