Article Synopsis
- Accurate preoperative landmarking of facial nerve branches is crucial in deep facial surgery to prevent nerve injury.
- A study dissected 33 cadavers to identify the position of the buccal rami in relation to a newly defined intercept landmark.
- Findings showed that 96.97% of the buccal rami were within 1 cm of the intercept, indicating that this landmark can reliably identify a "safe zone" for surgery where the risk of damaging the facial nerve is minimal.
Monitoring of benthic invertebrates in streams receiving acidic metal-contaminated water over an 18-yr period revealed both degraded conditions and recovery along a network of downstream locations. Compared with reference streams, and over the course of clean-up remediation efforts below an abandoned open-pit sulfur mine in the central Sierra Nevada of California, improving water quality was accompanied by recovery of benthic communities at some sites. Years of high flow resulted in degraded biological status when acid mine drainage capture was incomplete and metal loading had increased with runoff.
