Our retrospective study is about 70 cases of cancers of the Oral cavity, collected at the department of maxillo-facial surgery in Mohamed VI hospital university of Marrakech, during 9 years (January 2007-January2016). The mean age has been 60 years (20-94 years old). The women predominate with a ratio, which equal 0.94. Among the etiologic factors, tobacco is 31% of our cases and alcohol 6% of our case _Clinically, the mean delay of consultation has been 8 months_the clinical symptomatology has often consisted in the oral cavity lesions (80%), pain has been the second symptom (33%), the difficulty in swallowing and the difficulty in chewing (18%) and clinical examination showed a ulcero budding tumor in 38% of the cases, the cervical adenopathies have been noticed in 47% of the cases. The definitive diagnosis has been based on the histologic analysis that showed an epidermoid carcinoma in 87% of the cases. According to the TNM classification, the T3 are noticed in 46% and the No is found in 54%. The therapeutic strategy consisted in the surgery alone (58%), the surgery with radiotherapy (33%), the radiotherapy just (9%). Among our patients, we noticed a local recidivism in 3 cases, and we noticedtwo cases of metastasis, 35 patients (50%) are still a live with good carcinologic and functional result, 10 patients died; the other patients have been lost to follow-up.

Fractures of the frontal sinus are part of the fractures of the border between the facial and the cranial regions.They cause both aesthetic and vital problems, but also functional, requiring rapid and global care in a multidisciplinary setting. The document provides a descriptive and cross sectional study with prospective data collection, conducted in the department of Maxillofacial and Aesthetic Surgery of the Mohammed 6 Teaching Hospital of Marrakech, describe describe 18case operated for frontal sinus fractures over a 2-year period. The ideal time of repair was beyond the 72nd hour, at best between the 8th and 15th days after the reduction of cerebral and facial edema and the exclusion of any lesions that require emergency intervention. Our indications were mainly influenced by aesthetic deformities, impaction and embarrure fracture of ethmoidal and orbital roofs with clinical expression, obliteration of the naso-frontal duct, posterior wall displacement predicting dura mater laceration, and by the time to management. The coronal approach was the most indicated with 83, 33% of the cases. We realized sinus exclusion in 72.22%, cranialization in 22.77%, and repair of dura mater injuries in 27.77%. The sequelae found in 27.77%, were essentially functional and aesthetic.

The purpose of this work is to describe the surgical approach in some situations of laterofacial loss, which pose a problem concerning the moment of their repair and the choice of the technique to be used considering the attainment of noble elements. The study provides a descriptive and cross sectional study with retrospective data collection, conducted in the department of Maxillofacial and Aesthetic Surgery of the Mohammed 6 Teaching Hospital of Marrakech, on 82 cases of laterofacial cutaneous loss secondary to trauma and post tumor excision collected during 3 years. Etiologies were dominated by tumors in 60,97% of cases and trauma in 39,04%. The most frequent location was frontal and temporal in 41,46% of cases. Nobles elements were injured in 15,85%. 87,5% of traumatized patients had a primary reparation with locoregional flaps, while secondary reparation was proposed to 93,33% with malignant tumors until reception of histological results. The repair of laterofacial defects is subject to certain requirements before any surgery. Whenever usable, the locoregional reserve seems to us the most appropriate means of reconstruction.
