“…Despite the population differences observed, it is important to note that the study by Lemaire et al and Desai et al were a case study and as such despite the comparison, the low sample size in these studies might not yield the best comparison. 9,34 The differences observed might be due to genetic heterogeneity that may govern vascular development. Both radiological diagnosis and surgical approach depend on anatomical knowledge of the region and the variability in the vasculature involved.…”

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.

Background and Objectives: Typically, the external carotid artery (ECA) sends off separate anterior branches: the superior thyroid, lingual, and facial arteries. These could, however, form common trunks: thyrolinguofacial, linguofacial (LFT), or thyrolingual. Although known, the LFT variant was poorly detailed previously, and most authors just counted the variant. We aimed to demonstrate the individual anatomical possibilities of the LFT on a case-by-case basis. Materials and Methods: 150 archived angioCT files were used. After applying inclusion and exclusion criteria, 147 files of 86 males and 61 females were kept for this study. Results: In 34/147 cases, LFTs were found (23.12%). Bilateral LFTs were found in 13/34 cases (38.24%) and unilateral LFTs in 21/34 (61.76%) cases. Forty-seven LFTs were thus identified and further studied for different variables. Regarding the vertical topography of LFT origin, type 1a (suprahyoid and infragonial) was found in 28 LFTs (59.57%), type 1b (suprahyoid and gonial) was found in eight LFTs (17.02%), type 3 (suprahyoid and supragonial) was found in two LFTs (4.25%), type 2 (hyoid level of origin) in eight LFTs (17.02%), and type 3 (infrahyoid origin) in just one LFT (2.12%). Types of the initial course of the LFT were determined: type I, ascending, was found in 22/47 LFTs; type II, descending, in 12/47 LFTs; and type III, transverse, in 13/47 LFTs. Regarding the orientation of the first loop of the LFT, 23/47 LFTs had no loop, 4/47 had anterior loops, 1/47 had a posterior loop, 5/47 had superior loops, 5/47 had inferior loops, and 9/47 had medial loops. The position of the LFT relative to the ECA was classified as medial, anterior, or antero-medial. An amount of 12/47 LFTs were anterior to the ECA, 22/47 were antero-medial, 10/47 were medial, 2/47 were inferior, and 1/47 was lateral. Regarding their general morphology, 23/47 LFTs had a rectilinear course, 22/47 had loops, and 2/47 were coiled. A case-by-case presentation of results further demonstrated the diversity of the LFT. Conclusions: In conclusion, the morphology and topography of the LFT are individually specific and unpredictable. It can be anticipated case-by-case by surgeons on CT or MR angiograms.
