[Partial recovery of the oculomotor nerve after section and repair during the excision of a tumor].
The authors report the case of a patient having suffered a section of the oculomotor nerve during the excision of a tumor located in the tentorium incisura. The nerve was immediately sutured (end to end anastomosis). After 18 months, a partial recovery of the function of the nerve was seen clinically and on EMG. Ptosis had disappeared and adduction of the eye reappeared. An analysis of available data on the suture of oculomotor nerves is then given: reparation of the third nerve in animals and man give variable and partial results. Partial recovery and aberrant regeneration are explained by the fact that this nerve innervates many muscles and by the absence of ultrastructural systematisation. On the contrary, some still rare studies have indicated that the suture of the fourth and sixth cranial nerves give better results probably because these nerves have a simple ultrastructural organization, are purely motor and innervate only one ocular muscle.
