[Benef its of innovation in orthognathic surgery for OSA].

Obstructive sleep apnea (OSA) is a common, multifactorial disease resulting in high morbidity and mortality. Gold standard treatment is nocturnal positive airway pressure. Maxillomandibular advancement is a surgical technique used to treat obstructive sleep apnea.

[Dysfunction of the manducatory apparatus].

Temporo-mandibular disorders -TMD- involve a whole set of anatomical, physiological and clinical disorders that exceed by far the sole temporo-mandibular joint. The main symptom of this condition, most frequent in female patients, is pain. Three syndromes are associated with TMD: a muscular syndrome, not only involving masticatory muscles but also muscles of the neck and pain in seemingly unrelated anatomical regions, which can be misleading; an inflammatory articular syndrome; a mechanical syndrome affecting mouth-opening path.

Lack of efficacy of neoadjuvant chemotherapy in adult patients with maxillo-facial high-grade osteosarcomas: A French experience in two reference centers.

Introduction: Neoadjuvant chemotherapy (neo-CT) for osteosarcomas is the standard of care. Management of maxillo-facial osteosarcomas (MFOS) is challenging. In this rare disease, we collected a large cohort of patients with the aim to report the histological and radiological local response rates to neo-CT.

Rituximab as a trigger factor of medication-related osteonecrosis of the jaw. A case report.

Rituximab, an anti-CD20 monoclonal antibody, is an effective treatment for rheumatoid arthritis. Here we report the case of a patient with rheumatoid arthritis, having taken risedronate for 14 months to prevent corticosteroid-induced osteoporosis, more than 2 years ago, who presented osteonecrosis of jaw following herpetic gingivostomatitis two weeks after the beginning of a rituximab treatment associated with her usual anti-rheumatic drugs. Eight weeks later, no bone and/or gum healing was observed and a stage 2 medication-related osteonecrosis of the jaw (MRONJ) was diagnosed.

A retrospective study of pure medial orbital wall fracture management.

Purpose: To describe the clinical presentation of isolated medial orbital wall fractures, the duration of symptoms and their management.

Methods: Retrospective study of 60 orbits of 60 patients over 18 years of age with isolated medial wall fractures of the orbit at the facial and trauma center of the Pitié-Salpêtrière university hospital of Paris between June 2012 and November 2015. Diplopia, enophthalmos and limitation of extraocular muscle movements were investigated.

The parapharyngeal adipose corpus: anatomic and radiologic study.

Purpose: Although the morphology of the parapharyngeal adipose corpus (PAC) has been already described, the clinical interest of its volume and weight in the genesis of obstructive sleep apnea syndrome (OSAS) is still controversial. The volume of the PAC has been determined in OSAS patients but not in a normal population. The aim of our study was to investigate the morphology of the PAC by dissection and MRI in a normal population and to determine if there is a relation between the dimensions and volume of the PAC and the Body Mass Index (BMI).

Routine screening for HIV, hepatitis B virus and hepatitis C virus in individuals undergoing oral and maxillofacial surgery.

Objectives: Given the effectiveness of treatment of HIV, hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, there are considerable benefits associated with determining HIV/HBV/HCV status. We evaluated the feasibility and acceptability of systematic screening and subsequent care in an oral and maxillofacial surgery department.

Methods: The anaesthesiologists proposed screening for HIV, HBV and HCV to all individuals of unknown infection status undergoing surgery between 19 April 2016 and 19 April 2017.

Mandibular advancement reveals long-term suppression of breathing discomfort in patients with obstructive sleep apnea syndrome.

Obstructive sleep apnoea syndrome (OSAS) patients do not report breathing discomfort in spite of abnormal upper airway mechanics. We studied respiratory sensations in OSAS patients without and with mandibular advancement device (MAD). Fifty-seven moderate to severe non obese OSAS patients were asked about breathing discomfort using visual analogue scales (VAS) in the sitting position (VAS-1), after lying down (VAS-2), then with MAD (VAS-3).

Long-term effectiveness and side effects of mandibular advancement devices on dental and skeletal parameters.

Introduction: Continuous positive airways pressure, generally used to treat obstructive sleep apnea-hypopnea syndrome (OSAHS), is not tolerated well by many patients. An alternative is to treat OSAHS with mandibular advancement devices (MAD). This research assesses the long term (> 2 years) effectiveness and the side effects on dental and skeletal parameters of these devices.
