“…Secondly, postganglionic fibres are not very discriminating, but readily contact target opportunities along whatever path they happen to follow (Langley, 1897;Purves & Thompson, 1979). Finally, the cat sural nerve contains only about one-third of the fibres than the tibial nerve and thus fewer postganglionic fibres have the opportunity to innervate a relatively vast territory (McLachlan & Jiinig, 1983) and suturing a small nerve to a large stump is thought to favour regeneration and to minimize degeneration of unmyelinated fibres (Aldskogius, Arvidsson & Grant, 1985;Lisney, 1989).…”

SUMMARY1. The present study has investigated the reflex organization of sympathetic neurones and its control of autonomic effector organs following nerve injury and repair. A well-defined population of vasoconstrictor neurones supplying blood vessels of the hairy skin was forced to innervate a territory that contained some appropriate, but mainly inappropriate autonomic effector organs. For this purpose the central stump of the cut sural nerve was sutured to the peripheral stump of the cut tibial nerve 11-12 months prior to the terminal experiment.2. The activity of postganglionic sympathetic neurones was recorded from fine strands of the sural nerve proximal to the nerve lesion. Using a laser-Doppler device cutaneous blood flow was measured in the hairless skin of the hindpaw that was now reinnervated by the sural nerve. The results show a qualitative change of the reflex organization of sympathetic neurones following cross-union of these nerves.3. Stimulation of arterial chemoreceptors by ventilating the animals with a hypoxic gas mixture (8 % 02 in N2 for 3-8 min) increased the activity in twelve out of thirteen strands containing postganglionic sympathetic fibres. The increase of sympathetic activity contrasts with results from normal animals where systemic hypoxia causes a reflex decrease of activity in postganglionic fibres of the sural nerve.4. Reflex changes of sympathetic activity were closely followed by corresponding changes of cutaneous blood flow. Systemic hypoxia produced vasoconstriction in operated animals in contrast to the vasodilatation observed in normal animals.5. We conclude that the reflex organization of sympathetic neurones can change qualitatively following nerve lesion when sympathetic neurones regenerate and supply inappropriate target tissues. This long-lasting change reflects the plasticity of the autonomic nervous system and can produce a sustained abnormal control of reinnervated autonomic effector organs.

Endodontic incorrect preparation and overfilling can cause root canal filling material pushing into the adjacent vital anatomical structures such as maxillary sinus and mandibular canal. This condition can cause undesirable sensitivity symptoms. Although in some cases spontaneous resorption of some materials has been described; surgically removing the material presents the most favorable prognosis. In this study; a case of endodontic paste penetration both in maxillary sinus and mandibular canal which was treated by piezosurgery is presented.
