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.

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

Abstract

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

Abstract

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.

Primary diffuse large B-cell lymphoma of the ethmoid sinus: A case report

August 28, 2014  |  Jing-pu Yang, MD; Lian-ji Wen, MD; Chun-shun Jin, MD; Yan Liu, MD

Abstract

B-cell lymphoma of the paranasal sinuses is rare. We present the case of a 42-year-old woman who presented with proptosis, diplopia, and vision disturbances in the right eye. She was diagnosed with diffuse large B-cell lymphoma of the ethmoid sinus. We describe the general...

Anatomic measurements of the anterior and posterior ethmoid arteries in cadaveric heads using endoscopic sinus instrumentation

May 8, 2014  |  Zeeshan S. Aziz, MD; Ninef E. Zaya, MD; Richard M. Bass, MD

Abstract

The challenges of endoscopic sinus surgery lie in the complexity of the anatomy of the nasal vault and side walls and the proximity to critical structures. Additionally, operating in a three-dimensional space while relying on a two-dimensional image for surgical navigation can...

Pseudo third cranial nerve palsy secondary to orbital ectopic lacrimal gland cyst: Management with functional endoscopic sinus surgery

February 12, 2014  |  Puneet S. Braich, BSc; Jonathan E. Silbert, MD; Andrew J. Levada, MD; and Neil R. Schiff, MD

Abstract

An otherwise healthy 13-month-old girl was noted by her pediatrician to have developed a left head turn. The patient was referred to a pediatric ophthalmologist, who noticed signs of incomplete third cranial nerve palsy. Magnetic resonance imaging revealed the presence of an...
