Simultaneous intranasal procedures to improve chronic obstructive nasal breathing in patients undergoing maxillary (le fort I) osteotomy.
The aim of this study was to evaluate the safety and efficacy of septoplasty and inferior turbinate reduction, carried out through a Le Fort I osteotomy as part of the correction of a dentofacial deformity, designed to improve nasal breathing in patients who reported pre-existing nasal airway obstruction and had documented septal deviation and inferior turbinate hypertrophy. ⋯ The findings of this study indicate that simultaneous management of the maxillary jaw deformity (Le Fort I osteotomy) and intranasal pathology (septoplasty and reduction of inferior turbinates) were effective for the symptomatic relief of nasal airway obstruction. The complication rate for the intranasal procedures completed simultaneously with a Le Fort I osteotomy was minimal and not dissimilar to the rates reported for each procedure performed as an isolated event.

Randomized Controlled Trial Comparative StudyEffect of submucosal injection of dexamethasone on postoperative discomfort after third molar surgery: a prospective study.
The purpose of this study was to evaluate the effect of submucosal administration of dexamethasone sodium phosphate on discomfort after mandibular third molar surgery. ⋯ Parenteral use of dexamethasone 4 mg, given as an intraoral injection at the time of surgery, is effective in the prevention of postoperative edema. Increasing the dose to 8 mg provides no further benefit.

Comparative StudyQuantitative method to evaluate the functionality of the trigeminal nerve.
The primary objective of this study was to yield normal range values, with a current perception threshold technique, that could be used to assess the functionality of the third division of the trigeminal nerve on a healthy population. Moreover, we wanted to evaluate the impact of gender and training on these values. ⋯ The Neurometer can be beneficial for the evaluation and intraneural localization of sensory dysfunctions associated with the third division of the trigeminal nerve. It also could be used for initial diagnosis and subsequent evaluation of the patient's neurologic status through the course of their condition.

Comparative StudyPolycaprolactone-20% tricalcium phosphate scaffolds in combination with platelet-rich plasma for the treatment of critical-sized defects of the mandible: a pilot study.
Our group has recently fabricated 3-dimensional scaffolds of unique architecture to mediate favorable cell binding, proliferation, and differentiation. In this study, the osteoconductive and bioactive polycaprolactone-20% tricalcium phosphate (PCL-TCP) scaffolds were assessed for the treatment of critical-sized defects of the mandible, with respect to new bone formation. Platelet-rich plasma (PRP) was combined with some scaffolds to test if bone regeneration could be enhanced. ⋯ The pilot study showed that the treatment of critical-sized defects of the mandible with PCL-TCP scaffolds may be augmented by the addition of PRP.
