Use of Transcutaneous Electrical Nerve Stimulation (TENS) for the Recovery of Oral Function after Orthognathic Surgery.

J Clin Med 2022 Jun 7;11(12). Epub 2022 Jun 7.

Maxillofacial Surgeon, Ruber Hospital, 28040 Madrid, Spain.

The oral functions of patients are markedly diminished immediately after orthognathic surgery, and novel approaches are needed to accelerate their recovery. The aim of this study was to examine the usefulness of weekly applications of transcutaneous electrical nerve stimulation (TENS) for this purpose, based on the evidence of its effectiveness in other types of patients with muscle alterations. Maximum jaw opening, bite force, pain, and facial inflammation were compared between patients receiving TENS and those receiving sham-TENS for 30 min at baseline and weekly over a four-week period after orthognathic surgery and were also compared between the before and after of each procedure.

Pilot study of factors contributing to canine impaction after secondary alveolar bone grafting in unilateral cleft lip and palate patients.

Sci Rep 2022 May 20;12(1):8558. Epub 2022 May 20.

Division of Craniofacial Anomalies, Tohoku University Graduate School of Dentistry, Sendai, Japan.

Alveolar bone grafting (ABG) is broadly performed for cleft lip and palate patients. The rate of canine impaction post-ABG is much higher than the prevalence of canine impaction in non-cleft patients. This pilot study was designed to investigate factors involved in canine eruption failure after ABG and to predict the possibility of canine impaction in unilateral cleft lip and palate (UCLP) patients.

Virtual Surgical Planning (VSP) in Craniomaxillofacial Reconstruction.

Facial Plast Surg Clin North Am 2022 May;30(2):239-253

Division of Plastic Surgery, Department of Surgery, Obaid Center for Reconstructive Transplant Surgery, Mayo Clinic, MA1244W, 200 First Street Southwest, Rochester, MN 55905, USA. Electronic address:

The complex three-dimensional (3D) anatomy of the craniomaxillofacial skeleton creates a challenge for surgical reconstruction. Advances in virtual surgical planning (VSP) have enhanced reconstructive outcomes in craniomaxillofacial aesthetic and reconstructive surgery. This technology has been especially useful in spatially complex cases due to the ability to visualize and manipulate 3D configurations of the cranium through virtual surgery, printing of stereolithographic models, fabrication of cutting and positioning guides, creation of prefabricated hardware, and refinements of custom implants.

Virtual surgical planning and data ownership: Navigating the provider-patient-vendor relationship.

Bioethics 2022 06 22;36(5):494-499. Epub 2022 Apr 22.

Division of Medical Ethics, New York University School of Medicine, New York, New York.

The practice of modern craniomaxillofacial surgery has been defined by emergent technologies allowing for the acquisition, storage, utilization, and transfer of massive amounts of sensitive and identifiable patient data. This alone has thrust providers into an unlikely and unprecedented role as the stewards of vast databases of digital information. This data powers the potent surgical tool of virtual surgical planning, a method by which craniomaxillofacial surgeons plan and simulate procedural outcomes in a digital environment. Read More

Correction of Midface Deficiency in Patient With Crouzon Syndrome by Orthognathic Surgery and Patient Specific Facial Implant: Case Report.

J Craniofac Surg 2022 Mar-Apr 01;33(2):e191-e194

Department of Oral and Maxillofacial Surgery, School of Dentistry, Dental Research Institute, Seoul National University, Seoul, South Korea.

Abstract: Crouzon syndrome, also known as craniofacial dysostosis, is an autosomal dominant inherited disease characterized by early cranial fusion and consequential craniofacial malformations. In patients with Crouzon syndrome, the growth of the midface is affected due to early fusion of the cranial base, which results in exophthalmos, ocular ptosis, midface deficiency, and maxillary retrognathism. Frontofacial advancement using Le Fort III osteotomy is the conventional method for treating patients with Crouzon syndrome. Read More

Analysis of the effects of mandibular reconstruction based on microvascular free flaps after oncological resections in 21 patients, using 3D planning, surgical templates and individual implants.

Oral Oncol 2022 04 4;127:105800. Epub 2022 Mar 4.

Department of Oncologic and Reconstructive Surgery, Maria Sklodowska-Curie National Research Institute of Oncology, Poland.

Introduction: Post- resection defects in the area of the head and neck frequently result in functional impairment of the masticatory system and unaesthetic outcome in the facial appearance. In pediatric population they exert a devastating effect on speech development, breathing and facial growth leading to secondary deformations which are extremely challenging in reconstruction by means of conventional surgery protocols.

Material And Methods: 21 patients (14 males/ 7 females) aged 4-17 years old, treated between 2015 and 2019 due to malignant/benign tumors or congenital deformities requiring mandible resection were enrolled in the study. Read More

Graduate School of Dentistry, Osaka University, Suita, Osaka, 5650871, Japan.

This study aimed to establish a three-dimensional (3D) cephalometric analysis of craniofacial morphology and discuss its theoretical usefulness in orthognathic patients. Cone-beam computed tomography (CBCT) images of Japanese subjects with skeletal Class I malocclusion before treatment were selected from among 1000 patients so that samples matched a historic 2D cephalometric cohort with normal occlusion using propensity score matching. In each CBCT image, 67 3D measurements were calculated based on manually identified landmarks. Read More
