End-to-side neurorrhaphy

We developed end-to-side neurorrhaphy without incision or any injury to the donor nerve, which was the subject of our doctoral thesis, defended in 1992. This discovery was of the greatest importance, representing a paradigm shift in the physiology of peripheral nerves, opening up several new ones. research fields and numerous clinical applications.

Several works in this line were carried out by us and later by other authors.

This neurorrhaphy allows the use of a nerve as an axon donor, without any incision in it, thus avoiding any damage to its structure or denervation in its territory. Therefore, an almost infinite range of nerve options opens up to be used as axon donors.

This neurorrhaphy has been used by us in the treatment of facial paralysis, preservation of sensitivity after removal of the sural nerve and re-innervation of paraplegics.

Facial paralysis

Facial paralysis has several causes, which can be congenital, idiopathic, traumatic, or due to sequelae of oncological surgery and otitis media.

The most frequent is idiopathic or Bell’s palsy, as it is known. It occurs due to edema of the facial nerve inside the bony canal in the greater petrous bone.

The techniques most used today for resuscitation of the paralyzed face are “Cross-face nerve graft”, the transposition of the temporal muscle, the neurorrhaphy between the hypoglossal nerve and the injured facial nerve and the microsurgical transplant of gracilis muscle.

Our preference for recent paralysis is the “Cross-face nerve graft” with end-to-side neurorrhaphy. This means the placement of one or two sural nerve grafts connecting the normal facial nerve with the paralyzed nerve, with no section on any of these facial nerves.

In cases of old paralysis we use orthodromic transposition of the temporal muscle. Thus, to smile, the patient performs a small bite movement, contracting the temporal muscle and pulling the corner of the mouth, performing a smile movement.

Likewise, in congenital paralysis, we use orthodromic transposition of the temporal muscle.
One of the most serious situations in facial paralysis is Möebius Syndrome, a type of bilateral congenital paralysis. In these cases, we have used bilateral orthodromic transposition of the temporal muscle.

Paraplegics

Spinal cord injured persons, that is, paraplegics, present problems in the urinary tract, in the locomotor system and loss of sensation, with consequent muscular atrophies, osteoporosis and pressure ulcers.

All of this determines a terrible quality of life for these people.

To date, no efficient technique is available to restore these patients’ motor skills.

As for sensitivity in anesthetized areas, we have seen nerve grafts with end-to-side neurorrhaphy. This new technique was applied in two cases. In these patients, there was a return of sensitivity in both buttocks, thus avoiding the appearance of pressure ulcers.

Inclusions and fat grafts

Several patients have severe aesthetic deformities due to irregularities on the skin surface.

Many cases are due to changes in subcutaneous cell tissue. For many years we have been studying fat grafts experimentally and more recently alloplastic materials such as polymethylmethacrylate, polytef and bioplastic.

Liposuction

Liposuction is currently one of the most performed surgeries in plastic surgery. We have been studying several aspects related to it in animals in order to make it safer.
