Chronic Protracted Dislocation of Temporomandibular Joint in a Trauma Patient - A Case Report.

Rationale: Chronic protracted temporomandibular joint (TMJ) dislocation refers to a condition that persists for more than one month without reduction.

Patient Concerns: A 47-year-old male patient first presented to the Department of Maxillofacial Surgery complaining of the inability to close his mouth for nine months.

Diagnosis: Chronic protracted dislocation of the temporomandibular joint.

Assessment of epidermal growth factor receptor in histological, clinical and pathological staging of oral squamous cell carcinoma.

Background: Oral squamous cell carcinoma is an invasive epithelial neoplasm with varying degrees of squamous differentiation that arises from the following anatomic sites: the oral cavity, particularly oral soft tissues including the gingival and alveolar mucosa, floor of the mouth, tongue, soft and hard palate, tonsils and oropharynx. In normal epithelium EGFR is localized to basal cell layer, while its expression beyond basal localization in cancerous tissue suggest that correlation of EGFR and tumor progression might exist. The present study aimed to assess epidermal growth factor receptor in histological, clinical and pathological staging of oral squamous cell carcinoma.
