Kallikrein-related peptidase expression in odontogenic cysts and tumors: An immunohistochemical comparative study.

Aim: The aim of the present study was to profile the expression of human kallikrein (KLK)-related peptidases (KLK) in odontogenic lesions.

Methods: Paraffin-embedded, formalin-fixed, non-odontogenic (control) and odontogenic lesions were stained for KLK using a standard immunohistochemical technique. The intensity and proportion of epithelial cells stained was scored.

A modified retromaxillary approach to the infratemporal fossa: three case studies.

The infratemporal fossa (ITF) is an anatomically complex region with multiple neural and vascular structures entering and exiting through foramina in the skull base. The main obstacles to approaching the ITF are the zygomatic arch, the parotid gland, the facial nerve, and the ascending ramus AND condylar head of the mandible. Different surgical approaches to the ITF exist and the best approach should provide optimal visibility, minimal impairment of temporomandibular joint function, and preservation of motor and sensory nerve integrity.
