Nasoseptal Perforation: from Etiology to Treatment.

Purpose Of Review: Nasal septum perforation (NSP) is a communication between the two nasal cavities. This review contributes to the better knowledge of NSP causes, diagnosis, and treatment.

Recent Findings: NSP prevalence is about 1%.

Total septal perforation repair with a pericranial flap: Radio-anatomical and clinical findings.

Objectives/hypothesis: Endonasal surgeries are the primary cause of septal perforation (SP). However, trauma, inflammation, infections, neoplasms, or abuse of inhaled drugs can also cause SP. Septal repair is indicated in patients who experience nasal obstruction, crusting, intermittent epistaxis, purulent discharge, or nasal whistling and in those who fail conservative treatment.

Radio-anatomical analysis of the pericranial flap "money box approach" for ventral skull base reconstruction.

Objectives/hypothesis: To evaluate the versatility of the pericranial flap (PCF) to reconstruct the ventral skull base, using the frontal sinus as a gate for its passage into the sinonasal corridor "money box approach."

Study Design: Anatomic-radiological study and case series.

Methods: Various approaches and their respective defects (cribriform, transtuberculum, clival, and craniovertebral junction) were completed in 10 injected specimens.
