Survival Outcomes in Sinonasal Mucosal Melanoma: Systematic Review and Meta-Analysis.

: Sinonasal mucosal melanomas (SNMMs) are rare and aggressive malignancies with poor survival outcomes. Our systematic review and meta-analysis aim to evaluate overall survival (OS) rates in patients with SNMM; : We conducted a systematic search, following PRISMA guidelines across PubMed, Web of Science (WOS), and citation searching for studies reporting survival and prognosis outcomes for SNMMs. Inclusion criteria included studies with 5-year OS rates.

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.

Lacrimal duct Surgery: Different Techniques and Long-Term Postoperative Results.

Pre-saccal obstructions of the lacrimal duct can be solved with a conjunctivodacryocystorhinostomy while saccal or post-saccal obstructions are restored with an external, endoscopic or laser dacryocystorhinostomy (DCR). The aim of the present study is to review the indications for each technique and to compare the results achieved. Retrospective review of 335 patients in whom 440 surgeries of the lacrimal duct were performed, with at least 4 months of follow-up.

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.
