A study was undertaken to study the regeneration potential of surgically created parietal bone defects in newborn and fully grown rabbits. The results indicated that regeneration is greater in the newborn rabbits, especially if the periosteum and dura are preserved

Patients with severe mandibular prognathism are best managed with a combined orthodontic-surgical approach. In our patients, the orthodontic treatment consisted of six to eighteen months of presurgical preparation, which in some patients may accentuate the dental deformity. This is done to provide two well-aligned dental arches that will fit accurately at surgery. The surgical procedure used was an oblique subcondylar osteotomy. This was followed by six to eight months of orthodontic treatment to complete dental alignment. Thirty patients were treated using this combined approach, with excellent results and few complications

The skin-muscle flap technique in blepharoplasty has, in our opinion, distinct advantages over the classic skin flap operation. Morbidity is diminished by avoiding dead space and preserving the integrity of the skin-muscle intimate attachments. Excessive muscle, an entity of which we are becoming more aware, can be handled simultaneously by cautious excision. Finally, secondary operations to correct recurrent skin excess can be performed in virgin territory at the level of the skin-muscle interface. Even though this technique is applicable to the vast majority of patients, certain deformities in which a marked excess of skin is the chief anatomic problem are best corrected with a classic skin flap procedure

Single fibres were dissected from the dorsal spinal roots of the nerves serving the brachial plexus in African green monkeys. The dermatomal organization of these spinal nerves was deduced from data concerning the receptive fields of 2834 single afferent fibres. These data were collected in an attempt to reconcile some of the discrepancies that exist in published descriptions of the dermatomes in primates; our results and the literature reviewed suggest that the cutaneous region served by one spinal nerve is actually much wider and much more variable in location than is generally recognized. This makes any summary diagram a misleading indicator of the true complexity of the spinal innervation of the upper limb. In spite of this variability among individuals, within any specific individual there is a regular and orderly progression of innervation which allows prediction of the region served by a particular spinal nerve when information concerning the site of innervation of adjacent nerves is available. The territory of each myotome tended to be larger than the dermatome of the same spinal nerve. Most muscles of the limb received afferent innervation from three to four different spinal nerves. Further, the territory of the myotome did not of necessity coincide with the dermatome of the same spinal nerve. Even those nerves innervating the hand still innervated axial muscles. These observations have important implications for the diagnosis of spinal nerve injuries

For repair of radical mastectomy defects the surgical approach with the latissimus dorsi myocutaneous flap is presented. The application of this flap and complication are described. In addition 2 cases are presented illustrating a personal modification of the technics.
