good Parotid gland botox injection landmarks?

[FATPU$$YHUNTER]

most facial landmark based injection techniques for the parotid gland point to this paper as a reference: https://pn.bmj.com/content/practneurol/17/2/96.full.pdf

this guideline is kind of ass cause it doesn't account for the variability in parotid location and size in people, also doesn't give an injection depth: https://pmc.ncbi.nlm.nih.gov/articles/PMC7011800/pdf/MDC3-7-194.pdf

don't wanna fork the money over to buy an ultrasound machine, anyone know a better injection method?

this paper uses different sites https://www.e-arm.org/upload/pdf/arm-41-51.pdf, I feel like the one near the mastoid is too far back to be useful

I’d recommend buying a ultra sound machine
