A Relaxant of Very Brief Action

He mentions, too, quoting Patey, that the recurrence may arise from small satellite tumours indep'endent of the main one. The incidence of pa'rotid tumours, other than pleomorphic adenomas, makes any other clinical diagnosis than this u'nwise (except the obvious cancer), and their pathology demands that any surgical treatmnent should be wide excision. McKenzie (1948) has reiterated that Bailey (1948) is inccurate in his description of the gland as a bilobed structure. We have not found Bailey's analogy of the facial nerve as the filling in a parotid sandwich of any v4lue in removing parotid tumours, but our experience of facial-nerve branches and ifilaments makes us accept McKenzie's analogs of the parotid growing' like -a creeper, weaving itself into the meshes o'f a trellis-work fence (the facial 'nerve). Kidd (1950) h4s described identification of the cervical branch of the facial nerve in the, submaxillary triangle -as the ifirst step to preserve all the facial nerve. From dissections, however, this nerve appears small and might be difficult t'o find. One of us (W. IK. J. W.) has noted that it commnonly lies deep to the platysma I in. (1 cm.) behind the angle of the jaw, but this is inconstant.
