Cranial nerve V2 and Vidian nerve trauma secondary to lateral pterygoid recess encephalocele repair.

Background: The incidence of adverse sequelae related to trauma of cranial nerve V (V2) and the Vidian nerve (VN) during endoscopic pterygoid recess repair (PRR) of lateral sphenoid encephalocele is insufficiently reported in the medical literature. As part of our quality assessment and improvement program we sought to analyze the incidence and severity of V2 and VN injury during a 9-year experience (2010-2018) with PRR.

Methods: Hypoesthesia, paresthesia, and dry eye and their impact on patient quality of life were sought through chart review and a self-reported 0 to 5 Likert scale for each symptom.

Dystrophic calcification: A rare pediatric parotid mass.

Dystrophic calcification, the ectopic deposition of calcium in previously damaged or inflamed tissues, is an uncommon finding in the head and neck. Only a few cases have been reported in the parotidomasseteric region, and all of them have been located within and adjacent to the masseter. We present a case of dystrophic calcification occurring entirely within the parotid gland in a 7-year-old girl without apparent inciting inflammation, infection, or trauma.
