Effects of chorda-lingual nerve injury and repair on human taste.
Citric acid detection threshold and magnitude response were measured on the anterior tongue in 10 patients with unilateral chorda-lingual nerve transections before and after repair. Fungiform taste buds were analysed by videomicroscopy. Preliminary data suggests that humans can regenerate fungiform taste buds and recover some taste sensitivity after repair.
