Regenerated taste buds were first detected 5 to 8 months after surgery in 5 cases (Table 1). In 3 of 5 cases with regenerated taste buds, they were not found on the dorsal surface of the tongue but were found on the lateral border of the midlateral region. In the early stage of regeneration, taste buds without a taste pore or elongated taste bud–like structure were sometimes observed (unpublished data). In 2 of the 7 cases, taste buds were not regenerated throughout the observation period
