As with all complication in aesthetics treatments, the best form of management is prevention. If care is taken when placing the cannula near the parotid & submandibular gland, paying attention to more superficial and safe insertion under the parotid fascia. If this is not the case the cannula will become increasingly resistant and less able to move freely without force, through the tissues. This is an indicator that the cannula needs to be removed and repositioned in the interest of patient safety and comfort.
