Aesthetic surgery of the nose: Between caprice and necessity
Free oral communications 119 flap interposition seems to be a good possibility of treatment to functional rehabilitation of TMJ after disk destruction. Further examinations have to be done to explore the function of interponates in a long-term study.

mouth, the resulting scarring frequently produces limitation of mobility of the tongue. Following the treatment of carcinoma of the mandible, the tongue is generally fixed with the cheek and the prosthetic dental rehabilitation is difficult. In all these cases we have performed a secondary liberation of the tongue, with a full-thickness skin graft covered by an expander for 8 days. The mucosa is sutured over the skin graft and the expander which is then filled with a saline solution. This technique has been used in 6 cases and gives good results in mobility of the tongue, and allows a prosthetic dental rehabilitation.
Department of Oral and Maxillofacial Surgery, Municipal Hospital, Timisoara, Romania Tumours of the Submandibular Gland The lips are often the site of tumours more or less extensive, which require large resection, followed by defects of the whole lips or even exceeding them. The authors presents the experience of over 30 years of activity in this field, a period in which it has been used various surgical techniques. Surgical modifications for classic procedures are also presented, as well as original methods of lips plasty. The surgical technique aspect is accompanied by a vascular modifications study within various flaps, establishing on this basis the most ,propitious moment for corrective interventions.
Aesthetic Surgery of the Nose: Between Caprice and Necessity
Urtila E., Streian F., Pricop M., Bratu E. Department of Oral and Maxillofacial Surgery, Municipal Hospital, Timisoara, Romania The nose, anatomic element of great physiognomical value, is often the site of structural modifications, inborn or gained, which modify the general aspect of the face. For this reason, the aesthetic surgery of the nose is more frequently solicited. Patient requests are always accompanied by arguments which differ for every person. In most cases, these requests are objective and entirely justified. However, in some situations these are caprices, but for patients represent obsessive concerns. The authors present the evaluation of more then 1000 cases, accompanied by images, illustrating particular,situations, as well as surgical techniques for nasal plasty.
Use of Expanders in Functional Rehabilitation after Oral Malignancy Excision
Vacher C., Loncle T., Lezy J-P. Department of Maxillofacial Surgery, Hospital Beaujon Clichy, Clichy, France The authors present two techniques of rehabilitation after intraoral malignancy excision using expanders. 1. Following the treatment of carcinoma of the antrum by removal of the maxilla, we describe the use of an expander for 2 months after surgery, to prevent facial skin retraction. The expander, filled with air, is placed in the operative cavity between the cheek laterally, and a smooth temporary prosthesis which close the oro-antral defect. This technique has been used in 3 cases. In our experience it seems to give good results to prevent retraction of the cheek, if the expander is well tolerated during the period of radiotherapy. 2. Following the treatment of carcinoma of the floor of the
Valldosera M.A., Pamias J., Gonzalez J., Raspail G. Servicio de CirugIa Maxilofacial, Hospital General Universitario Vall d'Hebr6, Barcelona, Spain A retrospective study on survival of patients affected by tumours of the submandibular salivary gland was undertaken. The medical records of those patients were reviewed and the following data were compiled: age, sex, clinical staging, regional or distant metastasis, histologic diagnosis, surgical margins, therapy and disease status after last examination. A total number of 42 tumours could be identified, 13 being malignant. No sex differences were observed. All the cases of benign tumours were pleomorphic adenomas and one of them was a recurrent case. The most frequent malignant tumour was the adenoid cystic carcinoma followed by undifferentiated carcinoma. Our experience with those malignancies indicate that the main prognostic factors were pathology, clinical staging, and the state of surgical margins.
Experimental Palatal Mueoperiosteal Tissue Expansion
Van Damme P.A. 1, Freihofer H.P.M. 1, Maltha J. C.~, Kuijpers-Jagtman A.M. ~, van't HOF M.A. 3 Departments oflOral and Maxillofacial Surgery, 2Orthodontics and Oral Biology and 3Medical Statistics, University of Nijmegen, Nijmegen, The Netherlands The effects of experimental palatal mucoperiosteal soft tissue expansion were studied in 75 growing cats, with and without palatal scars, by means of two-dimensional cephalometric, three-dimensional morphometric, and histological analysis of data. The results indicate that significant soft tissue gain can be achieved by the tissue expansion technique. Surface-area increase was quantified in relation to the base surface and base diameter of the tissue expander. After 8 weeks of expansion, 85% surface area, 36% transverse, and 32% sagittal increments were reached. During active expansion, side effects were primarily anteroposterior and transverse growth retardation at the level of the bony palate and dentoalveolar structures, and accelerated vertical growth of the anterior naso-maxillary height. In the 8 week period after removal of the tissue expanders, significantly accelerated growth was found in scarred tissue expansion cases, with initial correction of the abnormal growth at the cranial base and/or palatal level. Histological evaluation showed marked thinning of the epithelial layers, thinning and alteration of the architecture of the connective tissue layers, development of a fibrous capsule surrounding the tissue expander, and resorption/depression of the palatal bone. The constitution of the capsule is likely to
