Abstract: Objective The number and distribution of lingual accessory foramen in the anterior region of mandible and the distance between the lingual accessory foramen and the alveolar crest in subjects of different ages and genders were analyzed to provide reference for safe operation in oral surgery. Methods Cone-beam computed tomography (CBCT) images of 200 eligible patients were chosen and grouped by gender and age to obtain the number and distribution of lingual accessory foramen in the anterior region of mandible and the distance between the accessory foramen and the alveolar crest. Statistical software SPSS25 was utilized to obtain the correlation between gender, age and the occurrence of accessory foramen. Results ①The incidence of mandibular accessory foramen for adult in Sichuan was 96.5%. ②There was no obvious difference in the incidence of mandibular accessory foramen between male and female subjects (P=0.706>0.05). ③ The incidence of mandibular accessory foramen in different age groups was significantly different (P<0.01) and negatively correlated with age (r=-0.307). ④ With the increase of age, the distance between the accessory foramen and the alveolar crest in the middle and left and right regions of the mandible decreased. Conclusion Most adults in Sichuan have mandibular accessory foramen, and the number of mandibular accessory foramen decreases with age. There is no obvious difference in the number of mandibular accessory foramen between male and female. Clinicians should pay attention to routine CBCT examination when performing surgery in relevant areas to prevent the injury of small arteries and nerve branches in the accessory foramen.
