Granulomatosis with Polyangiitis as a Cause of Sudden-Onset Bilateral Sensorineural Hearing Loss: Case Report and Recommendations for Initial Assessment.

Case Rep Otolaryngol 2021 20;2021:6632344. Epub 2021 Apr 20.

University of New Mexico School of Medicine, Department of Surgery: Division of Otolaryngology and Head and Neck Surgery, Albuquerque, NM 87106, USA.

Granulomatosis with polyangiitis (GPA) is a severe systemic vasculitis that commonly affects the paranasal sinuses, upper and lower respiratory tracts, and kidneys. GPA has also been associated with sensorineural hearing loss (SNHL), through inflammation of the cochlear apparatus. Early recognition, diagnostic laboratory evaluation, and appropriate treatment are essential to improve outcomes and achieve remission for patients with GPA. Read More

Surgery with Post-Operative Endoscopy Improves Recurrence Detection in Sinonasal Malignancies.

Ann Otol Rhinol Laryngol 2021 May 6:34894211011449. Epub 2021 May 6.

Department of Otolaryngology and Head and Neck Surgery, Thomas Jefferson University Hospital, Philadelphia, PA, USA.

Objective: The mainstay of treatment in sinonasal malignancy (SNM) is surgery, and when combined with chemoradiation therapy, often leads to the best overall prognosis. Nasal endoscopy is essential for post-treatment surveillance along with physical exam and radiologic evaluation. The ability to directly visualize the sinus cavities after surgery may also improve early detection of tumor recurrence and is another reason to potentially advocate for surgery in these patients.

Macroscopic anatomy, radiography and computed tomography of normal paranasal sinuses of the adult one-humped dromedary (Camelus dromedarius).

Vet Med Sci 2021 May 1. Epub 2021 May 1.

Department of Anatomy and Embryology, Université de la Manouba, Sidi Thabet, Tunisia.

In order to improve the current knowledge of the topography and the anatomy of the paranasal sinuses of the one-humped dromedary (Camelus dromedarius), we applied both conventional and advanced imaging techniques, namely, radiography and computed tomography (CT). Twelve heads of healthy dromedaries were used; eight heads were dissected to obtain skulls for the fenestration of the sinuses, two heads underwent anatomical sections, and two heads were imaged respectively by radiography and CT. Sinus fenestration allowed observation of sinuses and their communications. Read More

From ethmoidal air cells to ethmoturbinal passages.

Eur Ann Otorhinolaryngol Head Neck Dis 2021 Apr 27. Epub 2021 Apr 27.

ORL et chirurgie cervico-faciale, bâtiment Louis Mathieu, hôpital de Brabois, université de Lorraine, CHRU de Nancy, allée du Morvan, 54600 Vandœuvre-lès-Nancy, France.

The concept of ethmoidal sinuses composed of ethmoidal air cells does not appear to fit with the embryological origin of the ethmoid. Post-natal formation of the paranasal sinuses, as visualized by MRI, appears to be fundamentally different from the embryological development of the ethmoid sinus. These two organs also appear to have very distinct functions: paranasal sinuses play a role in respiration and sanitization of the respiratory tract, while the ethmoid sinus plays a role in olfaction.

Ancestry-based variation in maxillary sinus anatomy: Implications for health disparities in sinonasal disease.

Anat Rec (Hoboken) 2021 Apr 23. Epub 2021 Apr 23.

Center for Anatomical Sciences, Department of Physiology and Anatomy, University of North Texas Health Science Center, Fort Worth, Texas, USA.

Paranasal sinus drainage is mediated by mucociliary transport and gravity. However, human orthograde posture, along with the superior positioning of the maxillary sinus (MS) ostium, increases reliance on the mucociliary system. Previous research has thus suggested that differences in MS size and shape may impede mucociliary clearance, potentially contributing to disparities in sinusitis susceptibility. Read More

Dental findings on face and neck imaging.

Radiol Bras 2021 Mar-Apr;54(2):107-114

Hospital Sírio-Libanês, São Paulo, SP, Brazil.

When it is necessary to evaluate dental structures, the typical method is to obtain intraoral or panoramic X-rays at specialized dental clinics. However, in the daily practice of head and neck radiology, or even general radiology, it is common to encounter clinical situations or examination findings related to dental problems that should not be ignored. Because such problems can often be responsible for the clinical complaints of patients, this review aims to assist radiologists in identifying and describing common dental conditions on computed tomography of paranasal sinuses, face, and neck.

Septic cavernous sinus thrombosis: A review.

Surv Ophthalmol 2021 Apr 5. Epub 2021 Apr 5.

Department of Ophthalmology, Harvard Medical School, Boston, Massachusetts, USA; Ophthalmic Plastic Surgery Service, Massachusetts Eye and Ear Infirmary, Boston, Massachusetts, USA.

Septic cavernous sinus thrombosis (SCST) is a rare, yet severe, process typically arising from infections of the paranasal sinuses (predominately ethmoid and/or sphenoid sinusitis) and less commonly, otogenic, odontogenic, and pharyngeal sources. Clinical symptoms of SCST arise from obstruction of venous drainage from the orbit and compression of the cranial nerves within the cavernous sinus. In the preantibiotic era SCST was considered universally fatal (80-100%); however, with the introduction of antibiotics the overall incidence, morbidity, and mortality of SCST have greatly declined.
