TÍTULO
TREATMENT OF TRIGONOCEPHALY: A 10-YEAR EXPERIENCE'
AUTOR
Aristides Palhares, MD2; Silvio Zanini, MD3; Alcir Giglio, MD3; Roberto Gabarra, MD4; Adriano Y. Fernandes, MD4; Gimol Perosa4
  In the present study, cases of trigonocephaly treated in a public hospital along the past 10 years were analyzed. The aspects observed were: age at fnitial assessment; presence of cleft lip and palate; type of
surgical technique performed; and psychomotor development. The characteristics of the cases analyzed were similar to those observed in otherpopulations. However, the sample under investigation presented a
greater incidence of psychomotor retardation.
KEY WORDS
Trigonocephaly; surgery; psychomotor impairment.
TÍTULO
USE OF VIDEOENDOSCOPY IN CRANIOMAXILLOFACIAL SURGERY
AUTOR
Marcus Vinicius Martins Collares, MD, PhD'; Rinaldo De Angeli Pinto, MD2; Roberto Correa Chem, MD, PhD3; Gustavo Levacov Berlim, MD4
  Videoendoscopy in craniomaxillofacial surgery can be used for both diagnostic and therapeutic purposes.
In cases of trauma, it is used to approach zygomatic arch, condylar, and orbital fractures, among others. It also has an important role in orbital decompression, osteotomy, tissue expansion andplacement of osteogenic distractors. In all cases, the use of videoendoscopy leads to smaller incisions and less severe surgical trauma, and enables the surgeon to have a better view of certain anatomicalstructures, among other benefits.
With adequate training, the craniofacial surgeon can become acquainted with routine procedures related to videoendoscopy, which is a useful method in view of its several proved benefits.
KEY WORDS
Mavillofacial injuries; osteogenesis, distraction; tissue expanders; video-assisted surgery
TÍTULO
LONG FACE SYNDROME - SURGICAL TREATMENT
AUTOR
Luiz Carlos Manganello-Souza, MD, DDS, PhD'; Maria Eduina da Silveira, DDS2
  The authors report their experience in the correction of long face deformity. Le Foif I osteotorny with maxillary resection was the technique employed. Sagittal split osteotomy of the mandible was performed to correct anteroposterior displacement in 38 patients. Final results were considered good for 40 out of 45 patients treated
KEY WORDS
Prognathisrn; maxilla; surgey
TÍTULO
POROUS POLYETHYLENE IMPLANTS IN THE SURGICAL TREATMENT
OF DENTOFACIAL DEFORMITIES
AUTOR
Clarissa Turrer, MD1; Ricardo Cruz, MD2
  Acquired or congenital dentofacial abnormalities often require several surgical procedures until a satisfactory esthetic outcome and functional andpsychological improvement are reached. In some cases, when osteotomy andor the use of bone grafts are not sufficient, alloplastic materials become important tools. The objective of this study was to assess the efficacy of porous polyethylene implants as adjuvants to the treatment of complex dentofacial deformities. The case reports herein studiedshowed that these implants are an excellent choice for the surgical treatment of dentofacial deformities due to the biocompatlbillty and malleability of this material, available in several shapes and easy to adapt to the facial skeleton.
KEY WORDS
Polyethylene; surgery; facial asymmetry.

FALSE VS. TRUE MEDIAN CLEFT LIP: REPORT OF TWO CASES
AND DIFFERENTIAL MANAGEMENT
AUTOR
Marcus Vinicius Martins Collares, MD, PhDZ; Rinaldo De Angel1 Plnto, MD3
  Median cleft lip is a rare anomaly usually associated with other craniofacial and systemic malformations which can compromise survival and social relationship. Cases of median cleff lip can be differentiated
according to theirgenesis; the terms false and true have been used to identiveach of the types. In the true form, there is a split between the medial globularprocesses, while in the false form, agenesis of the globular processes is observed. Based on the different embfyologic, anatomical and clinical aspects of two typical cases treatedat the Service of Plastic Surgery, Hospital de Clinicas de Porto Alegre, Brazil, we discuss the most adequate diagnostic and therapeutic management for these patients.
KEY WORDS
Cleft lip; craniofacial abnormalities; holoprosencephaly
