Inverted papilloma is associated with greater radiographic inflammatory disease than other sinonasal malignancy.

Int Forum Allergy Rhinol 2020 03 5;10(3):278-281. Epub 2020 Feb 5.

Department of Otorhinolaryngology-Head and Neck Surgery, University of Pennsylvania, Philadelphia, PA.

Background: The pathogenesis of inverted papilloma (IP) has not been fully elucidated. However, chronic paranasal sinus inflammation has been anecdotally observed in sites distant from tumor obstruction in IP patients, suggesting an association between inflammation and IP tumorigenesis. This study assesses the association between sinonasal inflammation found in IP and compares this to the level of inflammation observed in other sinonasal tumors. Read More

Particle deposition in the paranasal sinuses following endoscopic sinus surgery.

Comput Biol Med 2020 01 4;116:103573. Epub 2019 Dec 4.

Department of Surgery, The University of Auckland, Auckland, New Zealand. Electronic address:

Optimizing intranasal distribution and retention of topical therapy is essential in the management of patients with chronic rhinosinusitis, including those that have had functional endoscopic sinus surgery (FESS). Computational fluid dynamics analysis has not previously been used to investigate sinus nasal spray delivery in the complete post-operative sinonasal geometries of patients who have undergone FESS. Models of sinonasal cavities were created from postoperative magnetic resonance imaging scans in four patients, three of whom underwent a comprehensive FESS, the other a modified endoscopic Lothrop procedure.

Atypical Presentation of Silent Sinus Syndrome: A Case Report and Literature Review.

Allergy Rhinol (Providence) 2020 Jan-Dec;11:2152656719899928. Epub 2020 Jan 14.

Department of Otolaryngology-Head and Neck Surgery, Johns Hopkins University School of Medicine, Baltimore, Maryland.

Introduction: Silent sinus syndrome (SSS) is a condition characterized by ophthalmologic features, such as spontaneous enophthalmos and hypoglobus with ipsilateral maxillary sinus atelectasis and an otherwise asymptomatic presentation. SSS has been documented secondary to a number of external causes, including trauma or surgery, but has less commonly been described in the setting of a potential mass in the deep masticator space.

Case Presentation: A 56-year-old woman with a history of chronic headaches with normal prior sinonasal imaging presented with increasing right-sided facial pain and headaches that radiated to her occiput, subjective visual changes, sharp ear pain, and long-standing subjective diminished sense of smell.

A case of acute unilateral maxillary atelectasis following endoscopic pituitary surgery.

Int J Surg Case Rep 2020 14;66:394-397. Epub 2020 Jan 14.

Department of Otolaryngology Head and Neck Surgery, Westmead Hospital, Sydney, Australia; Sydney Medical School, The University of Sydney, Sydney, Australia.

Introduction: Chronic maxillary atelectasis (CMA) is traditionally described as a rare, acquired condition of persistent and progressive antral wall collapse causing a reduction in maxillary sinus volume. In a handful of cases, CMA has been identified in patients with previously normal computed tomography (CT) imaging. However, maxillary atelectasis occurring rapidly after pituitary surgery, despite a normal pre-operative CT scan, has not previously been described in the literature. Read More

MR Findings of Fungus Ball: Significance of High Signal Intensity on T1-Weighted Images.

J Korean Med Sci 2020 Jan 20;35(3):e22. Epub 2020 Jan 20.

Department of Radiology, Seoul National University Hospital Healthcare System Gangnam Center, Seoul National University College of Medicine, Seoul, Korea.

Background: Central dark-signal intensity with high-signal, hypertrophic mucosal wall of paranasal sinuses on T2-weighted images (T2WI) is a characteristic magnetic resonance imaging (MRI) feature of sinonasal fungus ball. However, this finding is usually interpreted as non-fungal chronic sinusitis with central normal sinus air. In addition, T1-weighted images (T1WI) and T2WI are basic sequences of all magnetic resonance (MR) examinations. Read More

A pediatric case of central skull base osteomyelitis caused by Streptococcus milleri group infection and mimicking malignancy.

Childs Nerv Syst 2020 Jul 11;36(7):1569-1571. Epub 2019 Dec 11.

Department of Pediatrics, The Jikei University School of Medicine, 3-25-8 Nishi-shinbashi, Minato-ku, Tokyo, 105-8461, Japan.

Central skull base osteomyelitis (CSBO) that has expanded to the middle cranial fossa is a rare complication of nasopharyngeal infection in children. Diagnosing CSBO is challenging in children, because specific symptoms are lacking and imaging findings can mimic skull base malignancy. We report on a 3-year-old girl who complained of pyrexia, headache, and vomiting and in whom a mass around the clivus was detected with magnetic resonance imaging. Read More
