Nerve injury in fractures of the condylar neck.
Summary Although fractures of the condylar neck belong to the most frequent injuries of the jaws, and various nerves are found in close proximity to the temporomandibular joints, only little mention is made in the literature of neurological complications arising from accidents. We have therefore carried out a prospective study on nerve injuries in 237 fractures of the articular process in the period 1971–1975. We found two cases of post-traumatic Frey's syndrome, whereby the syndrome developed from a post-traumatic auriculotemporal neuralgia. We also found loss of function of auriculotemporal, buccal and facial nerves, and loss of taste sensation of the tongue in another case, caused by dam…
Repair of the mandibular nerve by means of autologous nerve grafting after resection of the lower jaw
Summary On the basis of two cases we demonstrate our method of autologous nerve grafting for substitution of the mandibular nerve after mandibular resection. The sural nerve served as a donor nerve, the graft was imbedded microsurgically at the juncture points by means of a perineurial interfascicular nerve suture. Oversized grafts of about 20 cm in length were chosen intentionally in order to insert them without tension between the stumps of the recipient nerve and outside the regeneration zone of the bone. In both cases complete resensibilization of the lower lip was reached after about six months.
Indication and technique for the reconstruction of nerve defects in head and neck.
Summary Although the results of peripheral nerve repair have been greatly improved in the last years following the introduction of microsurgery and increased application of free autologous nerve transplants, the use of restorative neuroplasty in maxillofacial surgery has been limited. Prompted by the successful reports on modern neuroplasty, we have introduced the use of autologous nerve transplant to bridge lesions of various cranial nerves. Our experience is based on the treatment of traumatic and tumour-induced defects of the facial nerve, inferior alveolar nerve, accessory and lingual nerve. The anastomosis of nerve was accomplished exclusively under the surgical microscope and microsur…
Diagnostic and therapeutic problems of myxomas (myxofibromas) of the jaws
During the period from 1969 to 1977 11 cases of myxoma or myxofibroma in the jaw region have been treated at the Maxillofacial Surgery Clinic of the University of Mainz. Various kinds of diagnostic problems are discussed. We observed, inter alia, rapid tumour growth and a imitative dynamics in the radiographs, giving rise to a suspicion of malignancy in some cases. The locally infiltrative type of growth of myxomas must be taken into account during therapy, since insufficiently radical management is liable to be followed by a recurrence.
The adenoid cystic carcinoma
Summary In spite of its rare incidence the adenoid cystic carcinoma must be treated with respect because of its hidden malignant character. In 5 out of 21 patients recurrences occurred much longer than5 years after he first operation. The extension of this tumour along branches of the trigeminal nerve could be well demonstrated in 7 of our patients where we were able to produce histological proof or radiographic evidence. The theory of tumour growth along the “tissue of least resistance” is illustrated by a special case report. As for the therapy, ultra-radical surgery has proved to be the most effective so far, whereas radio- or chemotherapy were only useful as palliative measures.
