Intubating a pediatric patient with temporomandibular joint ankylosis is a daunting task, and it becomes more challenging with limited mouth opening. Fiberoptic nasotracheal intubation technique is considered a gold standard. We describe an improvised technique of securing airway in the absence of appropriate-sized fiberoptic scope. The endotracheal tube inserted in the left nostril for maintaining depth of anesthesia was advanced under vision by the fiberoptic scope inserted into the right nostril, and with external laryngeal manipulation, the airway was secured with no complications...

OBJECTIVES: Patients suffering from osteoarthritis, ankylosis (e.g. post-trauma or tumour) in the temporomandibular joint (TMJ) can present with symptoms such as severely restricted mouth opening, pain or other dynamic restrictions of the mandible. To alleviate the symptoms, a total joint prosthesis can be indicated, such as the Groningen TMJ prosthesis. This was developed as a stock device with a lowered centre of rotation for improved translational and opening capacity. This study aimed to improve the design of the prosthesis, and produce a workflow for a customized Groningen TMJ prosthesis, in order to make it more accurate and predictable...

Axial spondyloarthritis (axSpA) is a common name for the non-radiographic form of the disease and radiographic axial spondyloarthritis, known as ankylosing spondylitis (AS). The disease is typically manifested at a young age, characterized by affection of axial skeleton, and in the most severe form can lead to complete ankylosis of the spine. Etiology of diseases have not yet been clarified, however, the genetic background, especially the binding to HLA-B27 antigen, is obvious. Clinical manifestations are dominated by chronic pain in the lower pain or buttocks that occurred in young age, in a large proportion of patients having the character of so-called inflammatory pain...

BACKGROUND: Orotracheal intubation in dogs is a common and easily-performed procedure that provides a patent airway during anaesthesia. In dogs with temporomandibular joint ankylosis or pseudo-ankylosis, airway management can be a challenging procedure since these dogs have a limited ability to open their mouth. Methods to provide safe, uneventful intubation in such patients may include minimally invasive techniques such as retrograde intubation using a guide wire and fibre-optic-aided laryngoscopy...

An avulsed tooth should ideally be replanted as soon as possible. Periodontal ligament (PDL) cells may survive for a short time in dry storage or storage in some physiologic media, enabling healing with normal PDL.1,2 However, after delayed replantation, when the extra oral drying time is longer than 60 min, the cells of the PDL will not survive.2-8 Despite this, even after long periods of dry extra oral time, delayed replantation is recommended although these PDL cells are necrotic.9,10 In such teeth ankylosis and osseous replacement are unavoidable, and the tooth will be eventually lost...

Background: Patients with limited mouth opening (LMO) often associated with difficult intubation. Retrograde intubation is an alternative technique of establishing definitive airway in these patients when blind nasal intubation fails and fiberoptic bronchoscope is not available. We tested the retrograde intubation through nasal route in patients with LMO less than 2 cm. Materials and methods: The procedure was performed with some modification with regard to retrograde guide on 18 patients requiring maxillofacial surgical procedures to increase mouth opening...

Malavika Subu, Jun-Young Paeng
Reduction malarplasty is one of the most commonly performed cosmetic and plastic surgery in Asian countries. Bony ankylosis of the temporomandibular joint (TMJ) occurs usually as a result of trauma, infection, failed surgeries, and autoimmune diseases. Reduction malarplasty has low incidence of TMJ-related complications. A 33-year-old female patient came with complaint of restricted mouth opening around 18 mm, which was developed immediately after the reduction malarplasty 2 years before. On computed tomography image, bony adhesion and the defect from the surgical drilling were found around right TMJ...

According to the American Association of Endodontists, "a 'true' vertical root fracture is defined as a complete or incomplete fracture initiated from the root at any level, usually directed buccolingually." Vertical root fracture (VRF) usually starts from an internal dentinal crack and develops over time, due to masticatory forces and occlusal loads. When they occur in teeth, those types of fractures can present difficulties in diagnosis, and there are however many clinic and radiographical signs which can guide clinicians to the existence of the fracture...

BACKGROUND: Primary failure of eruption (PFE) is a rare disease defined as incomplete tooth eruption despite the presence of a clear eruption pathway. Orthodontic extrusion is not feasible in this case because it results in ankylosis of teeth. To the best of our knowledge, besides the study of Ahmad et al. (Eur J Orthod 28:535-540, 2006), no study has systematically analysed the clinical features of and factors associated with PFE. Therefore, the aim of this study was to systematically evaluate the current literature (from 2006 to 2017) for new insights and developments on the aetiology, diagnosis, genetics, and treatment options of PFE...

Marshall F Newman, D Graham Lee, M Kinon Lecholop
Treatment of patients with bilateral temporomandibular joint (TMJ) ankylosis in a single-stage procedure can be challenging. The implementation of intraoperative navigation has proved beneficial by enabling faster and safer excision by providing real-time identification of vital structures. Navigation also can be used to verify site preparation for custom joint prostheses. This article seeks to establish a protocol, based on the use of intermaxillary fixation screws, to produce accurate and repeatable outcomes for the correction of bilateral TMJ ankylosis with total joint replacement in a single-stage procedure...

OBJECTIVE: Condylar and subcondylar fractures (CSFs) are among the most common mandible fractures. If reduction of these fractures is not carried out correctly, serious complications can result, including infection, damage to temporomandibular joint (TMJ) function, malocclusion, nonunion, malunion, and ankylosis of the TMJ. METHODS: We used a preauricular, mini-incision, open technique (PMIOT) for CSF of the mandible. 66 patients (48 males, 18 females), with a total of 72 CSFs of the mandible, were repaired with PMIOT between 2011 and 2016...

Preameloblast-conditioned medium (PACM) has been reported as a potent dentin regenerative material, but its effects as a mixture on periodontal regeneration and the role of CPNE7 in PACM are not known. The purpose of this study is to evaluate the histologic and histomorphometric effects of preameloblast-conditioned medium (PACM) and CPNE7 on periodontal tissue healing in dogs. Seventy-two mandibular premolar roots from ten dogs were extracted and randomly divided into six groups (n = 12 each): (1) positive control group; (2) negative control group; (3) cementum-removed and PACM-treated group; (4) cementum-preserved and PACM-treated group; (5) CPNE7-inactivated PACM-treated group; and (6) recombinant CPNE7-treated group...
