Early Surgery: Le Fort I Advancement in a 6-Year-Old Patient-A Therapeutic Approach Using a Modified Le Fort I Osteotomy.

Orthognathic surgery in young patients before completion of skeletal growth is still sharply discussed today. In the following case report of a 6-year-old patient, however, there was a vital indication for treatment. The main clinical symptoms were characterized by impaired hearing as a result of constantly recurring seromucotympanum and adenoids, persistent rhinorrhea and otorrhea, chronic tonsillitis and chronic otitis media.

Upper airway changes following high oblique sagittal split osteotomy (HSSO).

The aim of this study was to evaluate volumetric changes of the posterior airway space (PAS) following bimaxillary surgery using a high oblique sagittal split osteotomy (HSSO) of the mandibular ramus. The cone beam CTs of Class II and Class III patients taken before (T0) and 6-12 months after surgery (T1) were analyzed using 3D software (Mimics® Innovation Suite 18.0).

Moving the mandible in orthognathic surgery - A multicenter analysis.

Orthognathic surgery has always been a classical focus of maxillofacial surgery. Since more than 100 years, various surgical techniques for mandibular repositioning have been developed and clinically tested. Since the establishment of plate and screw osteosynthesis, orthognathic surgery became more stable and safe.

[Short sagittal osteotomy].

Bilateral sagittal split osteotomy has become the standard mandibular surgery for the treatment of dento-facial deformities. Even patients with less important deformities may undergo surgery. The morbidity must be as low as possible.

Influence of maxillary advancement surgery on skeletal and soft-tissue changes in the nose - a retrospective cone-beam computed tomography study.

Objectives: Surgical correction of skeletal maxillary retroposition is often associated with changes in the morphology of the nose. Unwanted alar flaring of the nose is observed in many cases. The aim of the present study was therefore to investigate the influence of surgical advancement of the maxilla on changes in the soft-tissue morphology of the nose.

Evaluation of surgically assisted rapid maxillary expansion with piezosurgery versus oscillating saw and chisel osteotomy - a randomized prospective trial.

Background: Ultrasonic bone-cutting surgery has been introduced as a feasible alternative to the conventional sharp instruments used in craniomaxillofacial surgery because of its precision and safety. The piezosurgery medical device allows the efficient cutting of mineralized tissues with minimal trauma to soft tissues. Piezoelectric osteotome has found its role in surgically assisted rapid maxillary expansion (SARME), a procedure well established to correct transverse maxillary discrepancies.

Root trauma and tooth loss through the application of pre-drilled transgingival fixation screws.

Unlabelled: Transgingival fixation screws are used for intermaxillary fixation in different situations. The aim of this study was to evaluate the risk of root trauma and tooth loss using pre-drilled transgingival fixation screws.

Material And Methods: 521 patients with mean age 26.

Use of stereolithographic drilling and cutting guides in bilateral mandibular distraction.

Mandibular distraction osteogenesis is used in the treatment of patients with syndromic and nonsyndromic class II mandibular hypoplasia. The three-dimensional distraction of the mandible is extremely complex. Past experience with mandibular distraction has demonstrated the indispensability of solid presurgical planning to achieve predictable results.

Changes after surgically-assisted maxillary expansion (SARME) to the dentoalveolar, palatal and nasal structures by using tooth-borne distraction devices.

Different devices are available to aid surgically-assisted maxillary expansion. In this study we have evaluated the changes to the anchoring teeth, the hard palate, and the lower nasal passage made by tooth-borne distraction devices. Thirty-one patients (mean (SD) age 28 (2) years) with deficiencies in the transverse width of the maxilla were examined by computed tomography and cone beam scans before and after operation.

Changes in the mandibular and dento-alveolar structures by the use of tooth borne mandibular symphyseal distraction devices.

Purpose: Different devices to perform a mandibular symphyseal distraction osteogenesis (MSDO) are available. This study evaluates how tooth borne distraction devices change to the teeth, the mandible and the condyles.

Materials And Methods: 19 patients (mean age 27.

Long term effects of surgically assisted rapid maxillary expansion without performing osteotomy of the pterygoid plates.

Purpose: Surgically assisted rapid maxillary expansions (SARME) are commonly used to widen the maxilla. This study evaluates long term stability of surgically assisted rapid palatal expansion without performing osteotomy of the pterygoid plates and its effects on nasal airway volume.

Materials And Methods: 13 patients (mean age 31, 23+/-6, 11) with a maxillary transverse deficit of at least 5mm were examined 1 month before and on average 63 months after a mean palatal distraction of 8.

Complications during mandibular midline distraction.

Objective: To analyze the number and type of complications during mandibular midline distraction.

Materials And Methods: The records of 100 consecutive patients who underwent mandibular midline distraction were evaluated, and complications which occurred up to 2 weeks after surgery were recorded.

Results: Fourteen patients had complications during the distraction period.
