dc.description.abstract | Study design: Descriptive cross-sectional study.
Objective: To determine the variations in origin of the LA and its relationship to surgical landmarks.
Background: The Lingual artery (LA) is a branch of the External Carotid Artery (ECA) that constitutes the principal
supply to structures within the oral cavity and floor of the mouth. Knowledge of its variant anatomy is therefore vital
during radiological and surgical procedures performed in the head and neck region since they may predispose it and other
branches of the ECA to iatrogenic injury. There is, however, a dearth of regional data on the same.
Materials and Methods: A total of 70 LA dissections were performed bilaterally on 35 human cadavers. The borders of
the carotid triangle were identified after which the external carotid artery and its branches were exposed. The pattern of
origin and the diameter of the LA was noted and distances from its origin to the CB, GCHB and the HN were measured.
Similar measurements were carried out for any variant trunks. Data was collected and analyzed using SPSS (IBM version 27).
A paired t-test was used to compare side differences. Representative photos of the vessel and its variations were taken.
Results: The LA was found to be present in all cadavers dissected and was bilaterally symmetrical in 43% of cases. Four (4)
types of branching patterns were encountered in the present study, the most commonly observed being the solitary LA
followed by the LFT, TLT and finally the TLFT. The average diameter was least in the solitary pattern and greatest in the
TLT. In relation to the CB, the solitary LA originated at a distance of 1.51 + 0.89 cm while the LFT, TLT and TLFT
originated at a distance of 1.80 + 0.73 cm, 1.02 + 0.64 cm and 1.25 + 0.01 cm respectively from the CB. The mean
distance from the origin of the LA to the GCHB was least in the TLT and greatest in the TLFT. With reference to the
hypoglossal nerve, the LA was at an average, 0.82+0.15 cm from the HN for the solitary pattern, 1.34+0.86 cm for the
LFT, 1.34 + 0.90 cm for the TLT and 1.38 + 0.93 cm for the TLFT.
Conclusion: The LA in the Kenyan population exhibited a high frequency of variation in comparison to other populations
regarding its pattern of origin and relationship to landmarks such as the CB, GCHB and HN. These findings may provide
further insight into the understanding of the vascular anatomy to the radiologist and the surgeon to avert complications
and improve overall treatment outcome. | en_US |
