One of the most common problems in otorhinolaryngology is perforation of tympanic membrane. Although many small perforations heal spontaneously over time, some may remain persistent due to infection or some other causes. In the past years so many grafts have been used with good success rate. In this prospective study of 60 patients with small tympanic membrane perforations, we have compared newer biomaterial collagen patch and conventional fat plug as office procedures in treatment. According to our study, both groups had a significantly equal success rates & the rate of healing & complete closure at the end of 1 & 2 months follow up. The hearing improvement in A-B gap during follow up of both groups were compared with pre-op A-B gap & showed a significant p value. This showed that both collagen patch & fat plug groups had a significant improvement in hearing following procedure. In our study quadrant of perforation does not correlate with the amount of hearing & healing rates were comparatively better in anterior quadrant than posterior quadrant. Infective causes were more & the failure rates were also high for such cause in both groups.

Physiological wound healing process can restore the functional and structural integrity of skin, but is often delayed due to external disturbance. The development of methods for promoting the repair process of skin wounds represents a highly desired and challenging goal. Here, a flexible, self-powered, and multifunctional triboelectric nanogenerator (TENG) wound patch (e-patch) is presented for accelerating wound healing through the synergy of electrostimulation and photothermal effect.

Chronic hard-to-heal wounds pose a significant threat to patients' health and quality of life, and their clinical management remains a challenge. Adipose-derived stem cell exosomes (ADSC-exos) have shown promising results in promoting diabetic wound healing. However, effectively enhancing the retention of exosomes in wounds for treatment remains a key issue that needs to be addressed.
