Neurosensory disturbances due to anterior loop (AL) injury are common postoperative complications from intraoral surgery in the premolar area, such as dental endosseous implants, genioplasty and open reduction of a mandibular fracture, so awareness by anatomical variations of the vital structure of the mandible is very important. Therefore, this study was carried out to analyze the AL of inferior alveolar nerve (IAN) by evaluating the CBCT-based characteristics of AL among Sudanese patients focusing on sex and bilateral differences.
A retrospective cross-sectional study of 50 cone beam computerized tomography (CBCT) images of the mandible of patients who attended the dental clinics in Khartoum city for different procedures in the lower jaw. Using Planmeca Romexis viewer 3D imaging software, the length of the anterior loop was calculated by measuring the distance in millimeters (mm) between the most anterior region of the loop and the medial margin of the maximum anterior portion of the mental foramen.
Twenty-six percent of the participants in this study had the anterior loop. The average lengths of the inferior alveolar nerves on the left and right ALs were 2.436 mm and 2.467 mm, respectively. It was more prevalent in the mesial to second premolar 5 (61,5%). A significant difference was found between gender and the presence of AL was more prevalent in female than male (P value = 0,0122).
The anterior loop of the inferior alveolar nerve does not have the same length on either side. Both male and female variations were equal.
