The TMJ articulation is a very complex system with muscles, ligaments and cartilage. The latest option is TMJ arthoplasty. The present work studies the behavior of a commercial fossa in a total TMJ implant. The most critical region is the first two screws in the condyle and the cranium. The fossa component presents some critical aspect in the stress observed. The contact point with the fossa co...

Aim: To analyse glenoid fossa position in Class I, II (div 1 and 2) malocclusions and to analyse variation in the shape of the glenoid fossa in different mandibular configurations. Materials and Methods: The cephalometric study was carried on lateral films of 45 subjects aged 12 18 years. They were divided into three groups based on the ANB angle (and anterior occlusal relation) and also based ...

The rhomboid fossa of clavicle is used to determine the age and sex in anthropology and forensic sciences. The variant types of rhomboid fossa on inferior surface have been reported in many races except in Thais. This study therefore was aimed at classifying the types of the rhomboid fossa in Northeastern Thais. The identified 476 Northeastern Thais dried clavicles (270 males and 206 females) w...

The piriform fossa forms the bottom part of the pharynx and acts as a pair of side branches of the vocal tract. Because of its obscure form and function, the piriform fossa has usually been neglected in the current speech production models. This study examines the geometric and acoustic characteristics of the piriform fossa by means of MRI-based mechanical modeling, in-vivo experiments and nume...

BACKGROUND Posterior fossa arteriovenous malformations (AVMs) are considered to have a higher risk of poor outcome, as are AVMs with associated aneurysms. We postulated that posterior fossa malformations may be more prone to associated feeder vessel aneurysms, and to aneurysmal source of hemorrhage. OBJECTIVE To examine the prevalence and hemorrhagic risk of posterior fossa AVM-associated fee...

Disease agents that principally target the tongue are relatively rare. It seems that type of food and roughage play an important role to predispose the animals to lingual ulcers. During a period of four years different aspects of cattle lingual fossa ulcer were studied in a semi-industrial dairy farm in Tehran. The affected animals showed various stages of ulcer formation in their lingual fossa...

A 16-year-old male presented with a massive nasopharyngeal angiofibroma arising in the nasopharynx, nasal cavity, pterygopalatine fossa, and infratemporal fossa, and eroding the pterygoid process of the sphenoid bone. Neuroimaging showed the tumor had infiltrated the parasellar region from the middle cranial fossa and reached the cavernous sinus. The tumor was almost completely removed macrosco...

BACKGROUND AND OBJECTIVES Fossa navicularis strictures following radical prostatectomy are reported infrequently. We recently experienced a series of fossa strictures following robot-assisted laparoscopic radical prostatectomy. Fossa strictures are usually procedure-induced, arising from urethral trauma or infection; catheter size has not been reported as a factor. We describe herein our experi...

The glenoid fossa is involved in approximately 10% of all scapular fractures.Glenoid fossa incongruity is surprisingly well tolerated.Surgery is recommended when 20% or more of the anterior glenoid fossa is involved.Glenoid rim fractures often lead to chronic shoulder instability.Unstable glenoid neck fractures need surgical treatment and stable fractures can be treated conservatively.CT examin...

Disorders of an organ not usually found in the right iliac fossa, such as the sigmoid colon, are an uncommon cause of right iliac fossa pain. We present a case of right iliac fossa pain caused by a sigmoid perforation due to involuntary ingestion of a rabbit bone, and describe the main features of this condition.
