Introduction: Third molar extraction is one of the most common surgical procedures in oral and maxillofacial surgery. Infectious complications can be estimated at 3.6% after local anesthesia., Observation: A 39-year-old female patient, presenting with important swelling of the face and neck after extraction of teeth 28 and 38 after local anesthesia. Clinical and radiographic data led to the diagnosis of facial cellulitis due to a foreign body on the sub angulo-mandibular region. Drainage under general anesthesia was performed and a fragment of anesthesia needle was removed. One month after surgery, the patient was considered cured., Discussion: Breaking an anesthesia needle is a rare accident, which can occur during oral surgery under local anesthesia. Respecting the rules of good practice is essential in preventing this type of complication, especially since forensic rules for dental and oral surgery are becoming stricter., (Copyright © 2013 Elsevier Masson SAS.

Background: Assessment of temporomandibular joint (TMJ) surgery is a controversial topic. We analyzed our long-term surgical results in a set of patients who underwent TMJ surgery in our unit from January 1995 through December 1996. We used a simple methodology based on 4 criteria: pain, mouth opening, type of feeding and patient satisfaction., Material and Methods: We reviewed 21 operated patients who had been managed by an orthodontist after surgery. The post-surgical follow-up was 4 years. Patient age at surgery ranged from 14 to 51 years; the sex ratio was 1/9 M/F. Seventeen patients suffered a closed-lock, 2 had fibrous ankylosis of the disc. Fifteen patients underwent bilateral TMJ arthrotomy with joint fixation and, very often, mandibulo-condylar-plasty to counteract the bony compression inside the joint. We rated outcome as "very good" if four factors were found: resolution or improvement of pain, more than 40 mm post-surgery mouth opening or at least 10 mm improvement for patients with less than 40 mm post-surgical mouth opening, normal feeding, subjective satisfaction rated as very or quite good. Outcome was thus rated as very good (4 factors), quite good (3 factors), good (2 factors), poor (1 factor), failure (0 factors)., Results: Resolution of pain was achieved in 55% of the patients with an improvement in the others. All patients recovered normal feeding. Mouth opening remained limited for two patients. Subjective patient satisfaction was very or quite good in 80% of the cases. Outcome was rated very good in 9 patients, quite good in 7, and good in 5. There were no patients with poor outcome or failure. Analysis of the good outcome group showed that 3 had experience a post-surgery trauma, one had not complied with rehabilitation therapy, and one suffered from undiagnosed rheumatoid polyarthritis., Conclusion: According to the literature, TMJ surgery is an effective means of treating pain and reducing dysfunction. We obtained good and stable outcome in patients who participated in our postoperative follow-up. The TMJ is a fragile joint particularly susceptible to trauma.

The incidence of osteomyelitis of the jaw has declined. Outcome is favorable with antibiotic therapy and surgery. We report a case in a women who experienced an unfavorable course with massive progressive diffusion, complicated by neoplastic conversion.

We report the case of a 75-year-old woman who consulted for suppurative gingivitis and maxillary deformation with slow progression and associated severe joint disorder. The patient suffered both esthetic prejudice and functional impairment. Clinical signs and radiographic findings suggested the diagnosis of fibrous dysplasia, in its leontiasis ossea form, rarely reported in the literature. Primum non nocere guided our management. Abstention, a simple remodeling resection, or extensive resection and reconstruction would have been inappropriate in this elderly patient. We opted for an orthognatic attitude in spite of the vascular risk inherent in the orthodontic preparation and the osteotomy on an abnormal dystrophic bone. Outcome was satisfactory.

Orthognathic surgery in patients with missing teeth can be divided into two categories. In the first case after tooth loss, specially designed bridging is required using the prosthesis already in place. In the second case in patients with congenital deficiencies, usually sequellae of cleft palate, there is a wider range of therapeutic options which are discussed on the basis of observed cases.

Among the numerous causes of facial neuralgias, the painful dysfunction syndrome of the manducatory apparatus corresponds to a frequent etiology whose thorough study carried out by a multidisciplinary team over about 500 cases allowed their splitting into several evolutive clinical forms. At present, a number of these forms which are particularly painful, require a disk surgery (dislocation reduction, perforation suture, etc.) and if necessary an articular facet surgery (modelling condylectomy, surfacing, etc.). This study specifies the indications and prognosis for these surgical operations.

52 cases of adenoid cystic carcinoma of the salivary glands are reported according to the age of the patient, to the localisation near an osseous structure or in soft tissues, to the histologic grade, to the therapeutic management, viz the surgical or radiotherapy treatment, correlated to the survival. It is worthy to notice that the localisations to the palate have a better prognosis than the localisations in soft tissues. Cribriform histologic grade in the same way have a better involvement than basaloid grade, but worse than tubular grade. Effectiveness of radiotherapy does not appear clearly in our study, unlike the observations of some authors.

We assessed the length and the quality of the remission of 13 unipolar endogenous depressed DST nonsuppressors before treatment in a 2-year prospective study. During this period, we recorded stressful life events. Persistent dexamethasone non-suppression after treatment and complete clinical recovery correlated highly with early clinical relapse. All six nonnormalizers but only one normalizer were rehospitalized within the following two years for a major depressive relapse. Persistent DST nonsuppression was unrelated to any impact of drug discontinuation, to the occurrence of stressful life events or to the length of illness-free intervals in the patient's prior course of illness. Persistent DST non-suppression appears to have a significant prognostic value.

The authors describe a technique of mobilisation of the frontal sinus using the fractures of anterior and posterior walls. The translesional approach is adapted to cranio-facial borders surgery of traumatisms. It's a skull base approach which minimizes the cerebral retraction and enables or perfect viewing of the top of the ethmoid. The advantages, drawbacks and indications are discussed about 25 cases.
