. Local and regional anesthesia : with chapters on spinal, epidural, paravertebral, and parasacral analgesia, and on other applications of local and regional anesthesia to the surgery of the eye, ear, nose and throat, and to dental practice. e, lower jaw, with pro-cessus coronoideus and temporal muscle (laterally) on the otherside, through into the fossa infratemporalis, and now endeavors byperforation of the pterygoideus muscle externus, which fills the entirefossa, to reach the planum infratemporale, in connection with which,as we have seen above, finger-feeling can be auxiliary only in a portionof the cases. We need, therefore, other fixed points. Such a point is THE HEAD, SCALP, CRANIUM. BRAIN, AND FACE 549 the depth. Before we stick the needle in we mark with the slidingcatch a distance of 5 to 6 cm.; in case of forward curving of the cheekby a tumor, still more. We are thereby always informed as to the depthreached, and can thus protect ourselves from gross errors. In thesecond place we must now consider a direction discernible on inspec-tion of the whole skull, and we have been able by careful observationand many examinations to establish as essential for the puncture ofthe foramen ovale the following fixed points:. Fig. 216.—Lateral route to foramen rotundum. (Braun.) (1) Viewed exactly from the front (for this determination ofdirection one must, like the designer, see with one eye only, and possiblywith the aid of a second cannula held freely before one), the cannulaintroduced into the ganglion points to the pupil of the eye on thesame side (Fig. 205). If we observe this rule, then we avoid deviat-ing outwardly into the fossa temporalis, inwardly into the tube andpharynx region. (2) On exact lateral inspection the cannula points to the tuber- 55° LOCAL ANESTHESIA culum articulare of the zygomatic arch (Fig. 205), If we do not ob-serve this rule, then it may happen that we come too far forward intothe fossa pterygopalatina, or too far back into the region
