The influence of the mode of treatment of zygomatic bone fractures on the healing process of the infraorbital nerve.

Several authors have described the influence of the method of treatment of a fracture of the zygomatic complex on the recovery of the infraorbital nerve. In this study, the results of treatment of 106 patients with an isolated, non-comminuted, unstable fracture of the zygomatic bone are presented. Thirty-eight patients underwent fixation with interosseous wiring and 68 patients were treated with a miniplate osteosynthesis across the frontozygomatic suture. In the group with wire fixation, 50% suffered persistent reduced sensitivity in the infraorbital region at follow-up examination, whereas in the group with a miniplate osteosynthesis only 22.1% had persistent neurological sequelae. On the basis of these findings we recommend a miniplate osteosynthesis in all unstable zygomatic bone fractures with displacement.

Hyperbaric oxygen treatment of chronic osteomyelitis of the jaws.

A review of the literature on treatment of chronic osteomyelitis of the jaws shows that hyperbaric oxygen is often recommended as an adjunct in treatment of this disease. Definite criteria to indicate this treatment and to evaluate the results have not been reported. The results of hyperbaric oxygen treatment of chronic osteomyelitis of the jaws in 16 patients are presented. In contrast to the good results reported in the literature, only 7 of our patients could be considered as cured. The reasons for this discrepancy are discussed. Our results, as well as the data from the literature, indicate that a combined antibiotic and surgical approach is the treatment of choice in chronic suppurative osteomyelitis. However, in chronic diffuse sclerosing osteomyelitis and in patients in whom decortication and antibiotic therapy have failed, hyperbaric oxygen treatment in combination with antibiotics and surgery seems to be indicated.

Downward displacement of the eye resulting from orbital emphysema (case report).

A case is reported of unusual downward displacement of the eye, occurring in a patient with fractures of the orbital floor and rim. On the basis of the clinical, roentgenological and computerized tomographic scan findings this is interpreted as resulting from a subperiosteal pneumatocoele above the eye ball.

Abnormal root development, probably due to erythema multiforme (Stevens-Johnson syndrome).

A case report is presented of a patient in whom nearly all teeth of the permanent dentition still present had short roots, while some teeth had never been formed at all. It may be concluded from the typical differences in length between the roots of the various teeth that this condition must be due to complete cessation of the growth of the teeth at the age of 7 or 8 years. Since the patient suffered a fulminant attack of erythema multiforme (STEVENS-JOHNSON syndrome) at this age, and since no other possible explanation of the short roots has been found, it is concluded that this clinical condition may have been the reason for the short root anomaly found. Damage or even destruction of the epithelial root sheath during the disease may be assumed to be the direct cause of the failure of full root development.
