Non-Surgical Management of the Gingival Smile with Botulinum Toxin A-A Systematic Review and Meta-Analysis.

Currently, concern about facial attractiveness is increasing, and this fact has led to orthodontics in adult patients being an increasingly demanded treatment, and with it, multi-disciplinary work. When it is caused by a vertical excess of the maxilla, the ideal solution is orthognathic surgery. However, in borderline cases and when the cause is hyperactivity of the upper lip levator muscle complex, alternative conservative solutions can be considered, such as the application of botulinum toxin A (BTX-A).

Minimally invasive surgical and miniscrew-assisted rapid palatal expansion (MISMARPE) in adult patients.

The purpose of this study was to evaluate maxillary expansion, operative time and pain associated with a new minimally invasive surgical technique to treat maxillary hypoplasia in adult patients. Consecutive patients were included and prospectively analyzed. The technique consists in miniscrew-assisted rapid palatal expansion (MARPE), minimally invasive approach to maxillary osteotomies, latency period and activation period until the desired expansion.

Le Fort I osteotomy and soft tissue response: A retrospective cohort study comparing three different techniques.

The aim of this study was to evaluate the nasolabial soft tissues effects in three different Le Fort I osteotomy techniques using cone beam computed tomography (CBCT) evaluation of three-dimensional (3D) volume surfaces. A retrospective study was designed, and three groups were evaluated: group 1, patients who underwent conventional Le Fort I osteotomy; group 2, patients who underwent subspinal Le Fort I osteotomy; and group 3, patients who underwent conventional Le Fort I osteotomy with ANS recontouring or removal. CBCT evaluation was performed at two time points: T0, 1 week before surgery; T1, 6 months after surgery.

Jawline Contouring Through an Intraoral Approach in the Context of Bilateral Sagittal Split Osteotomy: A Proof-of-Concept Report.

Purpose: This report describes a technique to suspend the submandibular space (SS) through an intraoral approach in the context of a bilateral sagittal split osteotomy (BSSO), thus improving the jawline contour and achieving a neck-rejuvenating effect.

Patients And Methods: A sample of 6 consecutive patients referred for orthognathic surgery who also sought neck rejuvenation and contouring surgery was selected to implement the technique. The following measurements were used to evaluate the procedure: patient satisfaction with a visual analog scale, photographic assessment, additional operative time, and complications related to the procedure.

[Soft tissue management to control nasal changes after Le Fort I Osteotomy].

Introduction: Adverse effects in the nasolabial region should be anticipated after Le Fort I osteotomy. Intraoperative factors such as the extent of surgical dissection, type of closure and perinasal soft tissue reconstruction seem to influence soft tissue response. Attempts to control these changes have been made over the years and several techniques have been proposed.

Three-Dimensional Analysis of Long-Term Stability After Bilateral Sagittal Split Ramus Osteotomy Fixed With a Single Miniplate With 4 Monocortical Screws and 1 Bicortical Screw: A Retrospective 2-Center Study.

Purpose: This study evaluated the long-term stability of bilateral sagittal split ramus osteotomy fixed with a single miniplate with 4 monocortical screws and 1 bicortical screw (hybrid technique [HT]) using 3-dimensional (3D) analysis and an objective measuring tool, cone-beam computed tomography (CBCT).

All patients underwent CBCT preoperatively, 1 month after surgery, and 12 months after surgery.

Surgery first in orthognathic surgery: A systematic review of the literature.

Introduction: Compared to the conventional approach to orthognathic surgery, "surgery first" protocols could be advantageous in terms of shortened treatment times and immediate esthetic improvement. However, consensus regarding patient selection, technical protocol, and stability is still lacking.

Methods: A systematic review of the scientific literature on surgery-first treatment (January 2000 to January 2015) was performed.

Malar Augmentation with Pedicled Buccal Fat Pad in Orthognathic Surgery: Three-Dimensional Evaluation.

Background: Contemporary orthognathic surgery contemplates three-dimensional facial soft-tissue harmonization as one of the basic pillars in treatment planning. In particular, prominent malar regions are regarded as a sign of beauty and youth by Western societies. The aim of this article was to perform a subjective and objective three-dimensional evaluation of the pedicled buccal fat pad technique for malar augmentation in the context of orthognathic surgery.
