Comparative Anatomy of the Contralateral Transmaxillary Approach Alone and With Ipsilateral Transpterygoid Extension: Quantitative Insights on Surgical Exposure and Maneuverability in the Petroclival Region.

Background And Objectives: Beyond qualitative evidence legitimizing endoscopic corridors through contralateral transmaxillary (CTM) and endonasal ipsilateral transpterygoid (ITP) corridors to the petrous apex and petroclival region, surgical feasibility by direct quantitative comparative anatomy is sparse. Our cadaveric study addresses this by performing the CTM approach followed by ITP extension to quantify the extent of petrous apex resection, instrument maneuverability, and working distance to petrous apex.

Methods: Anatomic dissections were performed bilaterally on 5 latex-injected human cadaveric heads (10 petrous bones).

Refining the role of cervical spine immobilization and stabilization in pediatric non-accidental trauma, a retrospective series of 1008 patients.

Introduction: Prompt detection of traumatic cervical spine injury is important as delayed or missed diagnosis can have disastrous consequences. Given the understood mechanism of non-accidental trauma (NAT), it is reasonable to suspect that cervical spine injury can occur. Current management of young children being evaluated for NAT includes placement of a rigid collar until clinical clearance or an MRI can be obtained.
