Abstract

We report a case of a middle-aged woman with a diffuse, nonenhancing, progressively atrophic T2-hyperintense lesion involving the left frontotemporal lobes and insula found to be synchronous high-grade sinonasal neuroendocrine carcinoma (SNEC) after initial endonasal resection...

Endoscopic view of a sinonasal osteoma

August 18, 2018  |  Dewey A. Christmas, MD; Joseph P. Mirante, MD, MBA, FACS; Eiji Yanagisawa, MD, FACS

Surgical intervention is indicated only in the event of symptoms or complications caused by the osteoma.

Choanal polyp originating from the superior meatus: An endoscopic view

July 18, 2017  |  Jae Hoon Lee, MD

In most cases, a choanal polyp is identified as an ipsilateral polypoid mass on endoscopy. Therefore, the main symptom of CP is unilateral nasal obstruction.

More than 20 years of powered endoscopic ethmoidectomy

October 25, 2016  |  Dewey A. Christmas, MD; Joseph P. Mirante, MD, FACS; Eiji Yanagisawa, MD, FACS

Current operative techniques continue to build on the foundation of functional endoscopic sinus surgery from the work of Messerklinger.

Onodi cell mucocele: Case report and review of the literature

September 19, 2016  |  John M. Lee, MSc, MD; Michael Au, MD

Abstract

Onodi cell mucoceles are rare entities that can cause devastating ocular complications if not treated promptly. Delays in the diagnosis are possible because of the wide range of differential diagnoses of unilateral retrobulbar optic neuropathy. We describe a new case of Onodi...

Endoscopic identification and powered removal of the uncinate process

April 30, 2016  |  Dewey A. Christmas, MD; Joseph P. Mirante, MD, MBA, FACS; Eiji Yanagisawa, MD, FACS

The identification and complete removal of the uncinate process results in a widened middle meatus and access to the ethmoid bulla, the frontal recess, and the outflow tract of the maxillary sinus.

Endoscopic view of a unilateral nasal soft-tissue obstruction

February 24, 2016  |  Joseph P. Mirante, MD, MBA, FACS; Dewey A. Christmas, MD; Eiji Yanagisawa, MD, FACS

It is often impossible to classify the disease process on the basis of endoscopic findings alone, but tissue biopsy and culture will lead to the appropriate diagnosis.

Nasal obstruction and recurrent sinusitis caused by bilateral pneumatized ethmoid bullae

December 14, 2015  |  Meir Warman, MD; Seth Willen, MD; Peter J. Catalano, MD, FACS, FARS

Abstract

The presentation of an enlarged pneumatized bulla ethmoidalis (BE) that obstructs the ethmoid infundibulum has not been previously reported. We report such a case in a 23-year-old woman who presented with recurrent acute rhinosinusitis and chronic rhinosinusitis. The...

Endoscopic view of a total ethmoidectomy prior to the FESS era

October 31, 2015  |  Eiji Yanagisawa, MD, FACS; Dewey A. Christmas, MD; Joseph P. Mirante, MD, FACS

Before the development of functional endoscopic sinus surgery (FESS), total intranasal ethmoidectomy was performed without the aid of telescopes.

Primary sinonasal meningioma in a child

September 21, 2015  |  Dodul Mondal, MBBS; Manisha Jana, MD; Prabir Kumar Sur, MD; Ebnam Murshed Khan, MD

Abstract

Meningiomas are common intracranial extra-axial masses. They are rarely encountered in extracranial locations; when they are, the most common head and neck locations are the paranasal sinuses and the temporal bone. Meningiomas in children are very rare, especially in the...

The ostium of the posterior ethmoid sinus seen in the superior meatus

July 21, 2015  |  Dewey A. Christmas, MD; Joseph P. Mirante, MD, FACS; Eiji Yanagisawa, MD, FACS

The division of the anterior from the posterior ethmoid cells is determined by the basal lamella of the middle turbinate.

Frontal recess polyp extending to the posterior choana-a frontal recess-choanal polyp

April 28, 2015  |  Dewey A. Christmas, MD; Joseph P. Mirante, MD, FACS; Eiji Yanagisawa, MD, FACS

Frontal recess-choanal polyps, as found in the case described in this report, are rare.
