Joint Ankylosis

AbstractThe purpose of this chapter is to inculcate a newer, deeper understanding of TMJ Ankylosis– both from the pathological as well as the clinical view point. Newer classifications may now determine surgical procedures. Interpositional materials may not be just soft tissues interposed between the cut ends, but also hard tissues forming the new Ramus Condyle Unit (RCU). Facial deformity may be recognized to be as important as inability to open the mouth; more so, if accompanied by Obstructive sleep apnea (OSA). Multi-staged treatment plans of release first followed by asymmetry correction may be replaced by single staged joint replacement & total facial aesthetic as well as functional rehabilitation. Finally, the importance of unfavorable events in TMJ Ankylosis surgery may be recognized, which would lead to better results in terms of treatment goals, i.e. to restore joint function, improve facial appearance & airway issues, correct malocclusion & re-establish harmony between the TMJ, the face and the teeth.

Require Data

Orthodontic diagnosis and treatment plans are determined based of some analyzes that require data derived from direct examination, study models, x-rays and clinical photos. Currently the clinical photos both intra oral and extra oral are easily made. Unfortunately, not all clinicians are willing to make good documentation especially making photos, or making the inadequate ones. The purpose in this paper to reveal how to make good intra and extra-oral photos for orthodontic records as communication features between clinician and patients. Proper documentation is needed especially on orthodontic treatment that requires a relatively long period. There are at least 5 intra-oral photos that should be made: frontal photo, right and left buccal, upper and lower occlusal photos. Extra-oral photos are relatively easier made than intra-oral photos. The important thing is position of the patient and the clinician. Four extra-oral photos are face-frontal with lips relaxed and smiling, profile and 45o profile will provide the maximum information about the face, soft tissues, proportions and esthetic smile. All important details should be recorded. Photos before, during and after treatment can be compared to recognize the changes that have been achieved. Good orthodontic records includes intra and extra-oral photograph taking will minimize the misunderstandings between the dentist and the patients in orthodontic treatment.

The Relationship

AbstractPreservation of the facial nerve is crucial in any type of facial procedure. This is even more important when performing plastic surgery on the face. An intricate knowledge of the course of the facial nerve is a requisite prior to performing facelifts, regardless of the technique used. The complex relationship of the ligaments and the facial nerve may put the nerve at an increased risk of damage, especially if its anatomy is not fully understood. There are several danger zones during dissection where the nerve is more likely to be injured. These include the areas where the nerve branches become more superficial in the dissection plane, and where they traverse between the retaining ligaments of the face. Addressing these ligaments is crucial, as they prevent the transmission of traction during facelifts. Without sufficient release, a satisfying pull on the soft tissues may be limited. Traditional superficial musculoaponeurotic system techniques such as plication or imbrication do not include surgical release of these attachments. Extended facelift techniques include additional dissection to release the retaining ligaments to obtain a more balanced and healthier look. However, these techniques are often the subject of much debate due to the extended dissection that carries a higher risk of nerve complications. In this article we aim to present the relationship of both the nerve and ligaments with an emphasis on the exact location of these structures, both in regard to one another and to their locations within the facial soft tissues, to perform extended techniques safely.

Tissue Abnormalities

Encephalotrigeminal angiomatosis, also known as Sturge-Weber syndrome or Sturge-Weber-Dimitri disease, is a sporadic congenital neurocutaneous syndrome characterized by angiomas of the face, eyes, and meninges. The typical clinical findings include seizures, a port-wine facial nevus, hemiparesis, and developmental delay. The classic intracranial imaging features of Sturge-Weber syndrome include cerebral hemispheric atrophy, hypervascularity and/or calcification of the cortex, and ipsilateral choroid plexus enlargement. Extracranial findings primarily include the vascular abnormalities of the ocular and facial soft tissues as well as hypertrophy of the calvarial and maxillofacial osseous structures. Additionally, we report involvement of the extraocular muscles, salivary glands, and lacrimal glands, findings that have not been well described in the literature. While a developmental venous pathology underlying Sturge-Weber syndrome has been proposed resulting in many of the findings, the mechanism behind the facial soft-tissue abnormalities and the clinical sequelae associated with these glandular abnormalities is still uncertain.Learning Objective: To recognize typical clinical and various imaging manifestations of Sturge-Weber syndrome, including head and neck and intracranial imaging findings

Background: The article presents our own experience of using computer tomography for identification of individuals with known results. Aims: The aim of the study was to verify the possibility of performing an identification study using a three-dimensional model obtained from computed tomography of the head. Identification was performed using a three-dimensional model of the head, based on computer tomography sections made in various projections, with a step of 1.231.25 mm. Two-dimensional images of the face (photos) were used for comparison. All comparative studies were conducted using approved methods of craniofacial and portrait identification: by reference points and contours. The experiment used a computer program that allows you to export DICOM-files of computed tomography results to other formats (InVesalius), as well as computer programs that directly work with the research objects (Autodesk 3ds Max, alternative programs Adobe Photoshop, Smith Micro Poser Pro). Results: In the course of research, it was found that, having computer tomography data of the head, it is possible to conduct identification studies on the following parameters: on the reconstructed three-dimensional model of the soft tissues of the face, on the three-dimensional model of the skull (craniofacial identification), on the features of the structure of the ear. Conclusion: Positive results were obtained when comparing objects, which makes it advisable to use them in practical and scientific activities.

The surgical management of paediatric patients with temporomandibular joint (TMJ) ankylosis, mandibular retrognathia and obstructive sleep apnoea (OSA) is challenging. We report a nine-year-old boy who presented to the Department of Oral Health, Sultan Qaboos University Hospital, Muscat, Oman, in 2016 with complaints of limited mouth opening, loud snoring and excessive daytime sleepiness. He was diagnosed with TMJ ankylosis, mandibular retrognathia and severe OSA. The patient initially underwent mandibular distraction and, subsequently, release of the TMJ ankylosis and rib graft reconstruction. The overall patient outcome was successful, with improvement in OSA-related symptoms, good facial symmetry and adequate mouth opening.Keywords: Temporomandibular Joint Disorders; Temporomandibular Ankylosis; Retrognathia; Obstructive Sleep Apnea; Case Report; Oman.

Bimaxillary Surgery

A new color-coded method of illustrating three-dimensional changes in the bone and the ratio of soft tissue to bone movement is described. The technique is illustrated by superimposing preoperative and 1-year postoperative CT scans of three patients following bimaxillary surgery. The method has proved to be a very simple, effective, and readily interpreted method of quantifying both bone and the ratio of movement of the overlying soft tissues across the face following surgery.
