Despite refinements in surgical technique, including bone grafting and sophisticated prosthetic reconstructions, there are limitations to what can be achieved with bone-anchored fixed prostheses in patients with advanced atrophy of the maxillae. A new approach was suggested by a long-term study on onlay bone grafting and simultaneous placement of a fixture based on a new design: the zygoma fixt...

BACKGROUND Total shoulder arthroplasty is technically demanding in regard to implantation of the glenoid component, especially in the setting of increased glenoid deformity and posterior glenoid wear. Augmented glenoid implants are an important and innovative option; however, there is little evidence accessible to surgeons to guide in the selection of the appropriate size augmented glenoid. M...

A case of cutaneo-cutaneous fistula superior to the external auditory canal extending from the mastoid skin to the skin over the zygoma is reported. The adult patient presented with recurrent discharge and swelling of the skin over the zygoma and mastoid bones. Definitive treatment was in the form of complete excision of the fistula tract.

Jacob disease is a rare condition consisting of pseudo joint formation between enlarged mandibular coronoid process and the inner surface of the zygoma. We report a 16-years-old male patient with Jacob disease who presented with restricted mouth opening and swelling of the right zygoma. In this report, clinical, radiological, and histopathological findings of the Jacob disease and its surgical ...

UNLABELLED The amount and direction of condylar growth, glenoid fossa displacement, and "effective" temporomandibular joint (TMJ) changes (a summation of condylar growth, glenoid fossa displacement, and condylar position changes within the fossa) were analyzed in 35 Class II, Division 1 malocclusions (23 boys and 12 girls) treated with the Herbst appliance. Lateral head films in habitual occlus...

  Background : Glenoid bone damages consisting of anterior rim erosion and bony avulsion are very important in decision making for treatment of recurrent dislocation in shoulder joint. This study was aimed to determine the prevalence of these damages in patients with anterior recurrent shoulder dislocation.   Methods : The study was a cross-sectional study evaluating patients with unstable shou...

Anatomy Shoulder stability is the end result of the shoulder stabilizing structures working properly together. The constraints on shoulder motion can be divided into static stabilizers and dynamic stabilizers (Table 1). Static stability is chiefly maintained by joint congruency, the labrum, and the shoulder ligaments. The glenohumeral joint is a ball and shallow socket joint with a constant mis...

BACKGROUND The conventional measuring method for glenoid version is greatly influenced by the scapular body shape that varies widely between patients. We postulated that the glenoid vault version could be more useful than the conventional glenoid version in clinical cases. OBJECTIVES The purposes of this study were to compare the values of glenoid version measured with the conventional method...
