Onodi cell mucocele: Case report and review of the literature

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


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


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


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.

Endoscopic view of a medial ethmoid drainage pathway into the middle meatus

February 2, 2015  |  Dewey A. Christmas, MD; Joseph P. Mirante, MD, FACS; Eiji Yanagisawa, MD, FACS

The ostium of the ethmoid bulla is often found in the hiatus semilunaris superior, but that it can also be found in the anterior or lateral wall of the bulla, the ethmoid infundibulum, the hiatus semilunaris inferior, or the retrobullar recess.

An uncommon cause of allergic fungal sinusitis: Rhizopus oryzae

January 19, 2015  |  Marie Devars du Mayne, MD; Maxime Gratacap, MD; David Malinvaud, MD, PhD; Frederic Grenouillet, PhD; Pierre Bonfils, MD, PhD


We report what we believe is the first case of allergic fungal rhinosinusitis (AFRS) caused by the fungus Rhizopus oryzae. Our patient was a 32-year-old woman who presented with unilateral nasal polyps and chronic nasal dysfunction. Computed tomography of the sinuses...

An unusual case of acute periorbital swelling

October 18, 2014  |  Sara Torretta, MD; Alessandra Brevi, MD; Davide Pagani, MD; Lorenzo Pignataro, MD


Periorbital swelling is frequently encountered in ear, nose, and throat practices and, as it may be secondary to acute sinusitis, delayed diagnosis may lead to significant morbidity. We describe the case of a 24-year-old man with acute ethmoid-maxillary sinusitis and...

Focal hyperostosis of an intranasal inverted papilloma observed on computed tomography

September 18, 2014  |  Jae-Hoon Lee, MD; Ha-Min Jeong, MD

Precise preoperative identification of the tumor origin is as important as detecting the extent of tumor invasion.
