The common anterior paralateronasal approach for malignant maxillo-mandibular tumors extending to the infratemporal fossa is usually difficult, insufficient, or even dangerous.. We report a new approach for tumors extending to the infratemporal fossa. It combines a paralateronasal and a cervical approach indicated for tumors extending to the infratemporal fossa, requiring a total monoblock excision of the tumor with as little esthetic sequel as possible.. The main interest of this technique is to offer a large exposure of the facial skeleton and the tumor, and to spare cervical vascular structures.

The aim of this article was to present a new method of analysis for the assessment of facial growth and morphology after surgical resection of the mandible in a growing patient.. This was a 2-year longitudinal study of facial growth in a child who had undergone segmental resection of the mandible with immediate reconstruction as a treatment for juvenile aggressive fibromatosis. Three-dimensional digital stereo-photogrammteric cameras were used for image acquisition at several follow-up intervals: immediate, 6 months, and 2 years postresection. After processing and superimposition, shell-to-shell deviation maps were used for the analysis of the facial growth pattern and its deviation from normal growth. The changes were seen as mean surface changes and color maps. An average constructed female face from a previous study was used as a reference for a normal growth pattern.. The patient showed significant growth during this period. Positive changes took place around the nose, lateral brow area, and lower lip and chin, whereas negative changes were evident at the lower lips and cheeks area. An increase in the vertical dimension of the face at the chin region was also seen prominently.. Three-dimensional digital stereo-photogrammetry can be used as an objective, noninvasive method for quantifying and monitoring facial growth and its abnormalities.

Chondrosarcoma of the maxillofacial region is a rare tumor. The classification of this tumor is based on histologic grades (1, 2, or 3) or variant including clear cell, differentiated, myxoid, and mesenchymal chondrosarcomas. However, histologic differentiation between this tumor and other relevant bone tumors is fairly difficult. Recently, molecular and genomic studies thought to be useful tools in a more definite diagnosis, accurate treatment, and quality of life of patients. The most acceptable choice of treatment of the chondrosarcoma is wide resection. Radiotherapy and chemotherapy as an adjunctive or palliative treatment remain controversial. The prognosis is different by histologic appearance and clinical behavior bases. However, lifelong follow-up is essential because chondrosarcoma shows a high incidence of local recurrence as well as regional and distant metastasis more than 2 decades later. This study presents 2 cases of chondrosarcoma with a long-term follow-up.
