To the best of our knowledge, this is the largest series reported to date of malignant tumors of the sinonasal tract and adjacent skull base treated with pure endoscopic or cranioendoscopic techniques. A 5-year disease-specific survival of 91.4% and 58.8% for the EEA and the CEA groups, respectively, seem to indicate that endoscopic surgery, when properly planned and in expert hands, may be a valid alternative to standard surgical approaches for the management of malignancies of the sinonasal tract.
Endoscopic surgery is a safe and effective treatment for paranasal sinuses FB. A proper imaging study by MR and/or CT can address diagnosis, which is based upon detection of fungal hyphae at histology.
We propose an improved oral cancer T staging system based on incorporation of DOI that should be considered in future versions of the AJCC staging system after external validation.
Our data confirm that nodal yield is a robust independent prognostic factor in patients undergoing END for cN0 oral SCC, and may be applied irrespective of the underlying patient population and treating institution. A minimum adequate lymphadenectomy in this setting should include at least 18 nodes.
Juvenile angiofibroma is a rare benign lesion originating from the pterygopalatine fossa with distinctive epidemiologic features and growth patterns. The typical patient is an adolescent male with a clinical history of recurrent epistaxis and nasal obstruction. Although the use of nonsurgical therapies is described in the literature, surgery is currently considered the ideal treatment for juvenile angiofibroma. Refinement in preoperative embolization has provided significant reduction of complications and intraoperative bleeding with minimal risk of residual disease. During the last decade, an endoscopic technique has been extensively adopted as a valid alternative to external approaches in the management of small-intermediate size juvenile angiofibromas. Herein, we review the evolution in the management of juvenile angiofibroma with particular reference to recent advances in diagnosis and treatment.
The improvement of surgical instrumentation and the experience acquired during a 14-year period have contributed to expanding the indications for endoscopic surgery in the management of JAs. Even stage III lesions may be successfully managed, unless the ICA is encased or if it provides an extensive blood supply. An external approach may be required when critical structures such as the ICA, cavernous sinus, or optic nerve are involved by lesions that are persistent after previous treatment; such a situation may prevent safe and radical dissection with a pure endoscopic approach. Better understanding of the factors influencing the growth of residual lesions is needed to differentiate those requiring re-treatment from those which can be simply observed.
NER is a feasible and minimally invasive surgical approach for the management of selected primary and locally recurrent NPTs. Our preliminary outcomes are promising, with local control rates comparable to those of conventional procedures. Larger case series and longer follow-up are needed to validate the reproducibility and efficacy of the technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
