Craniofacial Microsomia.

Clin Plast Surg 2019 Apr;46(2):207-221

Craniofacial Pediatrics, Seattle Children's Hospital, 4800 Sand Point Way, M/S OB.9.528, PO Box 5371, Seattle, WA 98105, USA.

Clinicians use different diagnostic terms for patients with underdevelopment of facial features arising from the embryonic first and second pharyngeal arches, including first and second branchial arch syndrome, otomandibular dysostosis, oculoauriculovertebral syndrome, and hemifacial microsomia. Craniofacial microsomia has become the preferred term. Although no diagnostic criteria for craniofacial microsomia exist, most patients have a degree of underdevelopment of the mandible, maxilla, ear, orbit, facial soft tissue, and/or facial nerve.

One-year postoperative skeletal stability of 3D planned bimaxillary osteotomies: maxilla-first versus mandible-first surgery.

Sci Rep 2019 Feb 28;9(1):3000. Epub 2019 Feb 28.

Department of Oral and Maxillofacial Surgery, Radboud University Nijmegen Medical Centre, Geert Grooteplein 10, 6525 GA, Nijmegen, The Netherlands.

Orthognathic surgery is carried out to correct jaw deformities and to improve facial aesthetics. However, controversy surrounds whether the maxilla- or mandible-first surgery approach leads to better surgical outcomes. In our previous study, we have shown that in most instances, the maxilla-first surgical approach yielded closer concordance with the 3D virtual treatment plan than a mandibular-first procedure.

Clin Oral Investig 2018 Aug 28. Epub 2018 Aug 28.

Craniofacial Center, Chang Gung Memorial Hospital, Taoyuan, Taiwan.

Objectives: Although several studies have reported the advantages of the surgery-first approach for orthognathic correction of Class III deformity, there are few reports of the success of this approach for patients with facial asymmetry. Therefore, the purpose of this study was to evaluate the outcome of bimaxillary surgery for asymmetric skeletal Class III deformity using a surgery-first approach.

Materials And Methods: Sixty-five patients who consecutively underwent at least a combined Le Fort I and a bilateral sagittal split osteotomy for asymmetric skeletal Class III deformity were identified in the authors' patient database. Read More

Comparison between patient specific implants and conventional mini-plates in Le Fort I osteotomy with regard to infections: No differences in up to 3-year follow-up.

J Craniomaxillofac Surg 2018 Oct 23;46(10):1814-1817. Epub 2018 Jul 23.

Department of Plastic Surgery, Cleft Palate and Craniofacial Centre, Helsinki University Central Hospital, (Head: Hannu Kuokkanen, MD, PhD), Finland.

Individually designed osteotomies and milled or printed patient-specific osteosynthesis materials are rapidly becoming a standard in maxillofacial reconstructive surgery. The benefits of using patient-specific implants (PSIs) in orthognathic surgery are especially clear in complex cases, and for this reason they are rapidly becoming common practice. We have earlier reported the benefits related to the use of PSIs as reposition and fixation system in Le Fort I osteotomy. Read More

The Use of Virtual Surgical Planning in Total Facial Skeletal Reconstruction of Treacher Collins Syndrome: A Case Report.

Craniomaxillofac Trauma Reconstr 2018 Sep 21;11(3):230-237. Epub 2017 Jul 21.

Department of Plastic and Reconstructive Surgery, JHMI, Baltimore, Maryland.

Facial skeletal reconstruction of patients with severe Treacher Collins syndrome (TCS) requires correction of both midface and mandibular deficiencies. Implementing virtual surgical planning can provide an accurate three-dimensional analysis of craniofacial abnormalities, creating calvarial donors that match the anatomy of the desired malar augmentation and facilitating bimaxillary movements, positioning, and fixation in orthognathic surgery. We present a case of an 18-year-old patient with TCS, who underwent staged zygomaticomaxillary reconstruction and double-jaw osteotomy with sliding genioplasty, using computer-assisted surgical planning.

Three-dimensional region-based study on the relationship between soft and hard tissue changes after orthognathic surgery in patients with prognathism.

PLoS One 2018 1;13(8):e0200589. Epub 2018 Aug 1.

Craniofacial Research Center, Chang Gung Memorial Hospital, Chang Gung University, Taoyuan, Taiwan.

Both deep understanding and reliable prediction of postoperative soft tissue changes are crucial for planning orthognathic surgery. Instead of estimating soft tissue responses by measuring individual landmark changes, this study aimed to investigate the relationship (ratio) between soft and hard tissue movements in different facial regions through three-dimensional cone-beam computed tomography (CBCT). Preoperative and postoperative CBCT images were superimposed using the surface registration method on the basis of the cranial base, and 10 facial regions of interest were defined. Read More

Temporomandibular joint arthritis: Clinical, orthodontic, orthopaedic and surgical approaches.

Int Orthod 2018 09 13;16(3):545-561. Epub 2018 Jul 13.

Département universitaire de chirurgie maxillo-faciale et stomatologie, hôpital Roger-Salengro, CHU de Lille, boulevard du Prof.-Emile-Laine, 59037 Lille cedex, France.

Rheumatic diseases (RD) of the temporomandibular joints (TMJs) are increasingly frequent affections and unfortunately often confused with "classic" manducatory dysfunctions (disk dislocation, myofascial pain syndroms). Their diagnosis is mandatory, given the major subsequent craniofacial disorders, which may occur (mandibular condylar hypoplasia, facial hyperdivergence, remodelling of the condylar unit, ankylosis), although the clinical implementation remains unspecific. The delayed diagnosis may be explained by the embryologic, anatomical and physiological characteristics of this joint. Read More

Use of an esthetic overdenture as an alternative treatment in a patient with bilateral cleft lip and palate.

J Prosthet Dent 2019 Feb 14;121(2):200-205. Epub 2018 Jul 14.

Assistant Professor, Department of Restorative Sciences, Dental College of Georgia, Augusta University, Augusta, Ga.

Stable occlusion and a pleasing esthetic appearance are often difficult to achieve in patients with congenital defects and severe midfacial deficiencies. Conventional therapy, such as orthodontic treatment followed by orthognathic surgery, is often not sufficient to fully correct the dental and esthetic problems. An interdisciplinary approach for these patients should include prosthodontic treatment that will assist in establishing a harmonious occlusion and improve facial appearance. Read More

Surgical Versus Nonsurgical Management of Degenerative Joint Disease.

Oral Maxillofac Surg Clin North Am 2018 Aug 5;30(3):291-297. Epub 2018 Jul 5.

Department of Oral and Maxillofacial Surgery, Virginia Commonwealth University School of Dentistry, Wood Building Room 311C, 520 North 12th Street, Richmond, VA 23298, USA. Electronic address:

As knowledge of the complexity of myofascial pain and its interaction with temporomandibular joint disorders has increased, the use of surgical procedures to treat degenerative joint disease has decreased. The focus has moved from a "surgery-first" approach toward a more cautious one that involves nonsurgical treatment as the primary modality, then minimally invasive treatments, followed by open surgical modalities, when indicated. This article examines the current literature regarding the effectiveness of nonsurgical and surgical treatments for the management of degenerative joint disease. Read More

High Fidelity Virtual Reality Orthognathic Surgery Simulator.

Proc SPIE Int Soc Opt Eng 2018 Feb 13;10576. Epub 2018 Mar 13.

Kitware Inc., Carrboro, NC.

Surgical simulators are powerful tools that assist in providing advanced training for complex craniofacial surgical procedures and objective skills assessment such as the ones needed to perform Bilateral Sagittal Split Osteotomy (BSSO). One of the crucial steps in simulating BSSO is accurately cutting the mandible in a specific area of the jaw, where surgeons rely on high fidelity visual and haptic cues. In this paper, we present methods to simulate drilling and cutting of the bone using the burr and the motorized oscillating saw respectively. Read More

Orthognathic Surgical Approach for Management of Skeletal Class II Vertical Malocclusion.

Contemp Clin Dent 2018 Jun;9(Suppl 1):S173-S176

Department of Orthodontic & Dentofacial Orthopaedics, Faculty of Dentistry, Meenakshi Ammal Dental College & Hospital, Deemed to be University, Chennai, Tamil Nadu, India.

The current era of orthodontics has evolved from regular dental corrections to achieve the most needed harmony between functional stability and esthetics enhancement of craniofacial structures. The "desire" for attaining this harmony led to the birth of orthognathic surgeries. The orthognathic approach has undergone a paradigm shift through the years, from correcting the skeletal component to addressing the soft tissues, thus optimizing esthetic outcome. Read More

Costochondral grafting for paediatric temporomandibular joint reconstruction: 10-year outcomes in 55 cases.

Int J Oral Maxillofac Surg 2018 Nov 28;47(11):1433-1438. Epub 2018 Jun 28.

Department of Maxillofacial Surgery, Great Ormond Street Hospital for Children, London, UK.

Costochondral grafting (CCG) can be used for the reconstruction of ankylotic, hypoplastic, and resected temporomandibular joint (TMJ) defects. CCGs have previously been considered the gold standard in children due to their growth potential and autogenous origin, but the disadvantages are unpredictable growth and joint ankylosis. This was a retrospective study of all children who received CCGs for TMJ reconstruction from 1985 to 2004, to allow a 10-year follow-up. Read More
