Abstract

Objectives:

Having observed variation in the breadth of surgeons' fingers whilst they are placing the incision for submandibular gland surgery, we aimed to examine this technique of incision siting, quantify the differences in fingerbreadths and consider any consequences of variability.

Methods:

Surgeons trained in salivary gland surgery were questioned on their method of incision placement for submandibular gland surgery. The breadth of index and middle fingers were subsequently measured using Vernier calipers.

Results:

The majority of surgeons use a measure of two fingerbreadths below the mandible in planning their approach to the submandibular gland. There is a significant difference in the size of surgeons' fingers, particularly between men and women (mean, 4.2 cm vs 3.6 cm).

Conclusion:

Fingerbreadth measurements are somewhat arbitrary, with significant inter-surgeon variability. However, based on the results of cadaveric studies, the findings indicate that the technique is safe for marking the incision in submandibular surgery.
