Predictability of Mandibular Autorotation After Le Fort I Maxillary Impaction in Case of Vertical Maxillary Excess.

A retrospective study of 20 patients treated for vertical maxillary excess between 2009 and 2010, solely by superior surgical repositioning of the maxilla. Clinical and radiological cephalometric parameters were analyzed statistically and their impact on achieving the predicted postoperative mandibular autorotation and on relapse. According to our study, patients presenting with an anterior open bite and a low occlusal plane angle might fail to achieve the predicted mandibular autorotation and are prone to postoperative relapse.

Microflora of normal maxillary sinuses: does it justify perioperative antibiotic treatment in sinus augmentation procedures.

Objectives: To investigate bacterial flora of normal maxillary sinuses in order to facilitate perioperative antibiotic management in sinus augmentation procedures.

Materials And Methods: Specimens of maxillary sinus mucosa were harvested during planned orthognatic surgery in 18 patients with no evidence of rhinosinusitis. The samples were processed according to hospital routine for aerobic and anaerobic cultures.

Sequence of treatment in mandibular prognathism patients.

Intraoral vertical ramus osteotomy (IVRO) and advancement genioplasty are effective and predictable methods of treating selective individuals with mandibular prognathism. The sequence of performing these procedures does have a clinical effect, but this is not found in the literature. The purpose of this article is to introduce the clinical implication of the sequence of procedures and to recommend the preferred sequence based on experience.
