AI Article Synopsis
- 24 adult dogs were divided into six groups for a study on nerve regeneration and taste bud restoration.
- In two groups, the lingual nerve was sutured to the glossopharyngeal nerve after transection, while in the other two groups, a neurectomy of the chorda tympani was done prior to the same suturing process.
- It was found that taste buds only began to reappear from the 8th week post-surgery in the dogs with the intact chorda tympani, highlighting significant differences in taste bud recovery based on the surgical methods used.
Article Abstract
24 adult dogs were classified into six groups; in 2 animals of each group the lingual nerve was transected distal to the point of entry of the chorda tympani and its proximal end was sutured to the distal end of the glossopharyngeal nerve. In the other 2 animals transtympanic chorda tympani neurectomy was performed before suturing the lingual and glossopharyngeal nerves. Invasion of the papillae by regenerating fibers from the 8th postoperative week onwards was followed by reappearance of taste buds only in lingual glossopharyngeal anastomosis with intact chorda tympani. The difference in number of taste buds, size and number of constituent cells between the two operative procedures was statistically significant from the 8th week onwards. The significance of these findings was discussed.
