Ossicular discontinuity is the most common cause of conductive hearing loss. Between 40 and 90% of tympanoplasties require middle ear ossicular chain reconstruction. The objective of this review is to segregate the literature on the outcome of various available graft materials in ossicular reconstruction, the preoperative predictors of ossicular necrosis and to find the risk of residual cholesteatoma in autologous incus ossiculoplasty.

- Third generation gravitational wave detectors aim to detect millions of binary black hole mergers, with about 1% being strongly lensed by galaxies, resulting in multiple observable GW signals.
- The analysis looks at how the number of lensed events and the distribution of time delays between them can help estimate cosmological parameters.
- This method offers insights comparable to traditional cosmological measurements but explores a different redshift range (z∼10), providing new opportunities in cosmological research.
Article Synopsis
- The study investigates compact binary coalescences with at least one component mass between 0.2 and 1.0 solar masses using data from Advanced LIGO and Advanced Virgo detectors over six months in 2019, but they found no significant gravitational wave candidates.
- The analysis leads to an upper limit on the merger rate of subsolar binaries ranging from 220 to 24,200 Gpc⁻³ yr⁻¹, based on the detected signals’ false alarm rate.
- The researchers use these limits to set new constraints on two models for subsolar-mass compact objects: primordial black holes (suggesting they make up less than 6% of dark matter) and
