The iliac crest region: donor site for vascularized bone periosteal and soft tissue flaps.

A review is presented of the classic vascularized iliac crest transfer and to show useful variations on this technique. A technical variation to reconstruct mandibular defects, the semisegmented iliac crest graft, is described. Another variation, the half iliac crest graft, is presented for use in the neovascularization of avascular necrosis of the femoral head. When such a flap is raised with a large periosteal flap and overlying muscle or skin, or both, as a composite flap, a primary osteoperiosteal tube can be created to reconstruct segmental defects in long bones. This primary osteoperiosteal tube is secondarily transformed into a completely osseous tube.

[Temporomandibular joint examination under general anesthesia--a case report].

Surgical interventions involving the temporomandibular joint are subject to strict indications. It further requires the exhaustion of all conservative treatment possibilities before operative procedures are considered. This case report involves a patient with an impressive TMJ dysfunction. After a series of frustrating attempts at functional treatment, surgical intervention was finally decided. Under general anesthesia however, the patient examination showed not even the least pathologic change in the passive joint function. Besides considering the discrete signs of possible psychiatric-psychosomatic causalities for such alterations, it seems to us that a temporomandibular joint examination under general anesthesia in such suspected cases has a diagnostic and therapeutic significance.

[Augmentation of severely atrophied jaws with hydroxyapatite from a prosthodontics standpoint].

After 4 years of routine application of hydroxylapatite ridge augmentation 109 patients underwent a posttreatment examination. The quality of the alveolar ridge and the denture as well as the functional status of the craniomandibular system were evaluated in detail. For the maxilla good results were obtained in 80-90%, for the mandible in 70-80%. Further improvements seem more probable by the avoidance of prosthodontic faults and the elimination of functional disturbances than by additional surgical procedures such as vestibuloplasty.

[Application of granulate hydroxylapatite for mandibular augmentation].

The already known surgical interventions for absolute induction of extensive mandibular atrophy, cannot be suggested as routine standardized methods. Use of Hydroxylapatite-ceramic for restoration of the atrophic alveolar process, shows several advantages; among those, simplicity of the operation use of local anesthesia, as well as very low percentage of unsuccessful interventions are taken into consideration. The clinical results of 102 cases are shown and discussed. Through the addition of H.A. ceramic in the field of preprosthetic surgery, there is a broadening of the spectrum of the therapeutic possibilities of patients with prosthetic problems to be expected.

[First results on the volumetric behaviour of osseous transplants after an avascular and reanastomosed transfer].

In this follow-up study the height of avascular and microsurgically reanastomosed osseous transplants serving for mandibular reconstruction is compared. For analysis a new computer-assisted method is applied which evaluates the plane of the transferred bone. As a result, it is revealed that the reanastomosed bone exhibits the better shape consistency than the avascular flap.
