[HTML][HTML] Morphologic mapping of the sublingual microcirculation in healthy volunteers
Journal of vascular research, 2022•karger.com
Purpose: Monitoring the sublingual and oral microcirculation (SM-OM) using hand-held vital
microscopes (HVMs) has provided valuable insight into the (patho) physiology of diseases.
However, the microvascular anatomy in a healthy population has not been adequately
described yet. Methods: Incident dark field-based HVM imaging was used to visualize the
SM-OM. First, the SM was divided into four different fields; Field-a (between incisors-lingua),
Field-b (between the canine-first premolar-lingua), Field-c (between the first-second …

Purpose
Monitoring the sublingual and oral microcirculation (SM-OM) using hand-held vital microscopes (HVMs) has provided valuable insight into the (patho) physiology of diseases. However, the microvascular anatomy in a healthy population has not been adequately described yet. Methods
Incident dark field-based HVM imaging was used to visualize the SM-OM. First, the SM was divided into four different fields; Field-a (between incisors-lingua), Field-b (between the canine-first premolar-lingua), Field-c (between the first-second premolar-lingua), Field-d (between the second molar-wisdom teeth-lingua). Second, we investigated the buccal area, lower and upper lip. Total/functional vessel density (TVD/FCD), focus depth (FD), small vessel mean diameters (SVMDs), and capillary tortuosity score (CTS) were compared between the areas. Results
Fifteen volunteers with a mean age of 29±6 years were enrolled. No statistical difference was found between the sublingual fields in terms of TVD (p= 0.30), FCD (p= 0.38), and FD (p= 0.09). SVMD was similar in Field-a, Field-b, and Field-c (p= 0.20–0.30), and larger in Field-d (p< 0.01, p= 0.015). The CTS of the buccal area was higher than in the lips. Conclusion
The sublingual area has a homogenous distribution in TVD, FCD, FD, and SVMD. This study can be a description of the normal microvascular anatomy for future researches regarding microcirculatory assessment.![](/scholar/images/qa_favicons/karger.com.png)
