The main reasons explaining TOF-MRA's lower accuracy include the ulcer's orientation and location in relation to the point of maximum stenosis and geometry in the form of neck-to-depth ratio [111].
We report a series of patients with melanoma of the head and neck with Breslow depths greater than 1.0 mm and clinically negative regional nodes that were evaluated prospectively with PET and lymphoscintigraphy.
There is currently no clear cutoff for a PAU diameter (depth) or neck diameter that warrants treatment, in one publication a depth of > 20 mm or a neck > 10 mm was associated with higher complication rates [26].
Changes in anaesthetic depth reveal neck representation in the whisker region in the threshold map that can be seen under light anaesthesia in animals if additional movements at suprathreshold currents are considered.
Future investigations on the effect of PS should consider a uniform design of RCTs preferably, with comparable conditions regarding the implant and abutment diameter, the implant-abutment connection type, the implant surface at the neck portion and insertion depth as well as longer observation periods of at least 5 years.
Thinking about FAI in terms of mechanical forms of injury allows for the recognition that variations in anatomy can cause impingement, including the cam 'bump', lack of head-neck offset, increased acetabular depth or protrusio deformity, acetabular retroversion, and, at the extremes of this spectrum, slipped capital femoral epiphysis (SCFE) and the sequelae of childhood Perthes' disease.
51 So the depth in certain neck acupuncture points may not show significant difference, such as expected in the limbs or the chest region between different genders.
Onat et al 47 suggested that NC can serve as a useful measure of central obesity, that is, participants with greater BMI may have greater NC, which leads to greater needling depth in the neck region.
Typical indications for adjuvant treatment included the presence of positive surgical margins when further surgery was not feasible, advanced neck disease, a tumor infiltration depth of more than 5 mm, extracapsular tumor spread, and infiltration of lymph vessels or nerves on histology.
