“…25 The effects of muscle reattachment comprise new bone formation to envelop the reorganizing tendon. 12 Similar fi ndings were observed after transposition of the masseter muscle. 26 Contour alterations of the angular process in the removal group were another important fi nding.…”

This study analyzed the effects of the unilateral removal and dissection of the masseter muscle on the facial growth of young rats. A total of 30 one-month-old Wistar rats were used. Unilateral complete removal of the masseter muscle was performed in the removal group, and detachment followed by repositioning of the masseter muscle was performed in the dissection group, while only surgical access was performed in the sham-operated group. The animals were sacrifi ced at three months of age. Axial radiographic projections of the skulls and lateral projections of the hemimandibles were taken. Cephalometric evaluations were made and the values obtained were submitted to statistical analyses. In the removal group, there were contour alterations of the angular process, and a signifi cant homolateral difference in the length of the maxilla and a signifi cant bilateral difference in the height of the mandibular body and the length of the mandible were observed. Comparison among groups revealed signifi cance only in the removal group. It was concluded that the experimental removal of the masseter muscle during the growing period in rats induced atrophic changes in the angular process, as well as asymmetry of the maxilla and shortening of the whole mandible.

“…The reattachment process includes superfi cial new bone formation. 12 Experimental alterations of the masseter muscle length can change the gonial region. 13 However, the role of the musculature in the process of bone formation is not well understood.…”

“…This temporary reduction of FHP-ABM angle may be related with the process of muscle reattachment which initially occurs at the center of the muscle and then develops toward the end of muscle. 21 In the 48-week animals, the FHP-ABM angle on the ostectomized side reached a nearly normal level. This process indicated that, although the reattachment site of the masseter muscle was relatively moved superiorly after MAO, the orientation of the masseter muscle remained unchanged.…”

Mandibular angle ostectomy is a common procedure for the correction of a prominent mandibular angle in Asia. However, the alterations of masseter muscles following resection of the mandibular angle are not well known. In this study, 12 adult rhesus monkeys were used to investigate the effects of mandibular angle ostectomy on the masseter muscle. Mandibular angle ostectomy was performed on one side of the mandible and the other side remained intact and was used as normal control. Four animals were randomly killed at 12, 24, and 48 weeks postoperatively, respectively. The morphologic, histologic, and electromyographic examinations were used to compare the differences of masseter muscle between the ostectomized and normal sides. On the ostectomized side the electromyographic activity, cross sectional area, mass, thickness, and length of the masseter muscle were all decreased, despite a trend to recover with time. Histologic examination showed that the muscular reattachment on the ostectomized side resembled normal muscle attachment eventually. The results showed that secondary atrophic changes would occur in the masseter muscle after mandibular angle resection. This study may be helpful for predicting the final cosmetic outcomes of mandibular angle ostectomy.

“…The use of polymers in the medullary canal of the bone implants was indicated with the purpose of increasing their resistance (O'Brien, Straw, & Withrow, 1993;Straw & Withrow, 1995). The polyurethane resin, developed by Chierici and Miller (1984), was used in dogs by Ignácio in 1999 and by Maria (2001), showing to be biocompatible and biotolerant without presenting osseointegration.…”

The major malignant tumors found on the chest wall are sarcomas, including osteosarcomas, chondrosarcomas, fibrosarcomas, and hemangiosarcomas. Treatment of cancer, as well as chronic chest wall conditions, require radical surgical excision of the involved tissues. In addition to surgery, chemotherapy plays a role as adjuvant treatment in tumors affecting the chest wall, reducing chances of metastasis and prolonging the disease. The restoration of the chest wall has the main objective to restore the respiratory function, for this, a procedure is necessary that keeps the chest closed and stable. There are many materials used for chest repair, such as autogenous, synthetic, homologous and heterologous tissues. The main objective of this literature review is to address the main malignancies that affect the chest wall, as well as the resources most used to repair the damage caused by aggressive surgery in an attempt to promote greater safety margins.
