[Transoral coronoidectomy: Technical note].

Introduction: Among the skeletal causes of limited mouth opening, uni- or bilateral coronoid process hypertrophy, or Langenbeck disease, is the most frequent. It can be associated with an osteochondroma or a coronoid-malar bone conflict and is then called Jacob disease, an unilateral pathology. Treatment rests on coronoidectomy in both cases.

Wharton's duct retropapillary approach.

Salivary lithiasis is more frequently encountered in patients with Wharton's duct. They are often treated with a minimally invasive technique, such as sialendoscopy. The problem with sialendoscopy, in some cases, has been that it will not be possible to cannulate the papilla and, thus, sialendoscopy will not be feasible.

[Comparison between Polyglactin 910 (Vicryl®) versus irradiated Polyglactin 910 (rapid Vicryl®) for mucosal suture after wisdom teeth avulsion].

Introduction: Two different types of suture are used in our unit after wisdom tooth extraction, Polyglactin 910 [PGS] (Vicryl®, Ethicon) and rapid absorption irradiated Polyglactin 910 [PGI]. No objective comparative study was available so we decided to conduct a preliminary prospective study to check if there was any difference between these two types of suture.

Patients And Methods: Forty patients were included in our study, consecutively operated for impacted wisdom teeth by the same surgeons, between April and June 2010.

[Is orthognathic surgery an alternative for mandibular osteopetrosis?].

Introduction: Osteopetrosis is a metabolic bone disease that leads to bone malformation and bone healing disorders. We report the case of a patient who underwent orthognathic surgery to treat a class III skeletal malocclusion.

Observation: A 21-year-old patient had presented with osteopetrosis in his childhood, which had been treated by bone marrow transplantation.
