A statistical comparison of treatment changes in twenty patients treated with a Fränkel appliance and twenty treated with the Edgewise mechanism. Both groups showed similar improvements, with no significant differences in mandibular growth.
An x-ray cephalographic method was used to analyze 52 exceptionally well-balanced white adult faces for skeletal asymmetry in the posteroanterior (PA) projection. Three frontal facial lines were constructed using bilateral skeletal landmarks: latero-superior orbit (LO), lateral zygoma (Zyg), and gonion (Go). All subjects demonstrated measurable asymmetries. Data showed less asymmetry and more dimensional stability as the cranium is approached. A slight tendency toward right-side dominance was not statistically significant.

The term "Big Nose" describes many deformities caused by hypertrophy of the bone or the cartilagenous framework of the nose or both. This leads to disharmony of the face, which discomforts the patients. By diminution of the naso-labial angle as for example in a "Pinocchio nose" or by the reduced angle of the inner valve like in a tension nose, a "Big Nose" presents not only an aesthetic problem but a functional one too. An exact analysis of the deformity is necessary to choose the adequate operative procedure. The reduction of the nose should lead to an improvement in "looks" as well as in breathing. The most challenging factor in nose reduction is the diminution of the tip projection. Two different methods are mainly available: the technique according to Goldman and to Lipsett. The pros and cons of both are compared and a few refinements suggested.
Eighty-four patients with basal cell carcinoma of the head and neck were submitted to surgery. In 75%, infiltration of the reticular dermis or the subcutis was documented. Primary closure of the wound was achieved in only one-third of these patients. In the remaining cases, the defects were closed by local flaps, regional flaps or a microvascular forearm flap. In 86% of the cases, good-to-excellent results were achieved.

The septo-rhinoplasty is a standard procedure in head and neck surgery. Only slight modifications have been developed during the last years concerning especially the surgery of the septum, the tip of the nose and the osteotomies. The presently well favored "external rhinoplasty" is not of any advantage and should be restricted to only few indications. In the present paper the different surgical approaches are described for the various nose deformities of adults and especially for those problems related to children.
This paper describes a method of calf augmentation by using gel-filled implants to correct thin or asymmetrical legs. The implants are placed over both heads of the gastrocnemius muscle beneath the fascia cruris superficialis. In order to simplify Glitzenstein's procedure, modified implants were developed by the author. In over 30 cases, this technique gave encouraging results.

During the early phases of single-implant treatment, clinician needs and patient expectations can be challenging. This article describes a technique for making a simple bonded provisional restoration. In addition to minimizing patient discomfort without increasing laboratory costs, the technique enables soft tissue preservation through all treatment phases, from tooth loss to implant loading.
This article presents a technique to enhance the optic qualities of all-ceramic crowns when placed over a cast post and core. An opaque layer is necessary over a metal structure, such as a cast core, to reduce light absorption and increase the reflectance of the metal. The desired effect is to raise the value of the core in order to approach the optic qualities of dentin. However, the problem of reflectance is fully eliminated by the use of an opaque layer of ceramic. The translucence of a ceramic crown may not be limited by the use of opaque material under the crown. This procedure requires the placement of an opaque layer of ceramic on the core, thereby moving such a layer 0.3 to 0.5 mm more deeply from the surface of the restoration. This allows more depth and translucence to the crown, as light penetrates further into the crown.
This article describes a direct procedure for the expeditious fabrication of provisional restorations for extensive fixed prosthodontic applications. Customary indirect or indirect-direct approaches require extensive clinical time as well as laboratory support for their successful application. Provided that the necessary preoperative steps are followed precisely, this treatment method allows for excellent clinical results while being less time consuming.
