Our experience in petroclival lesions using a contralateral transmaxillary approach.

Petroclival lesions represent a surgical challenge during the endonasal endoscopic approach, as they may involve maneuvers with severe comorbidity. To avoid the morbidity caused by these maneuvers, a contralateral transmaxillary approach (CTA) has been proposed to complement the endoscopic endonasal approach. The aim of our study is to review the safety and efficacy of this approach.

Section and repositioning of the inferior turbinate in the design of extended septal flaps.

Background And Objective: Nasoseptal or septal flaps extended to the floor of the fossa and inferior meatus are a resource in the reconstruction of extended endoscopic approaches. We propose the technique of sectioning and repositioning the inferior turbinate to facilitate the design of these extended pedicled flaps.

Material And Methods: We evaluated 3 cases operated with a skull base lesion: a craniopharyngioma, a petroclival meningioma and a post-surgical fistula of cerebrospinal fluid in the cribiform plate, in which sectioning and repositioning of the inferior turbinate was performed prior to the design of a septal or nasoseptal flap extended to the floor and inferior meatus.

Our experience in the management of orbital complications in acute rhinosinusitis.

Background And Objective: The spread of an infection from the paranasal sinuses is rare but severe. Between 4% and 20% of all rhinosinusitis can become complicated, orbital involvement being the most frequent (60-75%). Orbital complications are more common in children but more severe in adults.
