The purpose of this study was to assess the position of the temporomandibular joint articular disc through
magnetic resonance imaging in patients with prognathism submitted to orthognathic surgev. Twenty
temporomandibularjoints of 10 prognathic patients were assessed by magnetic resonance, with oblique sagittal TI planes and mouth open and closed, and with oblique sagittal T2planes and mouth closed. The patients were
assessed before and affer surgery for the comparison of articular disc position. All patients were submitted to
sagittal split osteotomy of the mandible and were assessed 6 months postoperatively (at minimum). In the
preoperative assessments, eight joints presented normally positioned discs, 10 presented anterior disc
displacement with reduction, and two had anterior disc displacement without reduction. In the postoperative
assessments, the disc was normally positioned in eight join6 10 presented anterior disc displacement with
reduction, and two presented anterior disc displacement without reduction. In conclusion, 80% of the articular
discs maintained their preoperative position, 10% improved from anterior disc displacement with reduction to a
normal position, and 10% presented anterior disc displacement with reduction in contrast with an orignally
normally positioned disc. |

The purpose of the present study was to investigate body image through self-evaluation in patients presenting
facial trauma and being followed at the Division of Plastic Surgery; Hospital das Clinicas, Universidade de SBo
Paulo, Brazil. Twenty patients (males and females) with agesranging from 18 to 52 years were assessed. Facial
trauma affected the patients'lives both physically and psychologically, making social readjustment more dificult.
Body scheme alterations led to changes in body image. Patients showed high expectations in relation to
reconstructive procedures; this situation contributed to maintain the high level of anxiety obsewed prior to surgery |

Currently: several centers of craniofacial surgery advocate the use of secondary alveolar tissue grafts forpatients aged
9 to 11 years, since this would be the most appropate time in tfe for tooth migration and eruption. Alveolar bone
(sponge bone) is the preferred tissue for the performance of the gmft, andone ofthe main donorsites is the iliac crest,
which offers a great amount oftissue. A study was canied out at our institution (SOBRAPAR) to compare two surgical
techniques used to remove bone tissue from the iliac west: one via an osteotome and the other via a bone extractor
developed at our institution. Both procedures were compared in terms of operating time, intraoperat~veh emohage,
size of the scar; postoperative duration of pain andparesthesia. The iliac crest revealed to be an excellent donor site
of sponge bone both in quantiiy and qualiiy me use of the bone extractorrevealed to be practical, efficient, safe and
associated with befferfum7onaland aestheticresults when cornparedto the usualslugicaltechnique (with an osteotome). |

This article aims at describing the authors'experience with hyperbaric oxygen therapy (HBOn as an important
resource in mandibularbone loss reconstruction, mainly in cases that require correction of great defects caused
by resections camed out to treat benign but highly invasive diseases. The protocol for the use of oxygen under
pressure is presented and the indications and limitations of HBOT are discussed. |

APPLICATION OF BIODEGRADABLE MATERIALS IN PEDIATRIC CRANIOFACIAL
SURGERY |

Biodegradable materials, mainly polylactide and polygycolide polymers and copolymers, are currently used in
craniomaxillofacial surgery as fixation materials. Several research groups have shown that such materials
adequately work in the fixation of osteotomies and fractures in the craniofacial skeleton. The main advantage of
these materials in pediatric craniofacial surgery is related to the grovdh of the facial bones. This article presents
an overview of the development of biodegradable materials, their characteristics and different applications in
craniofacial surgery. |
