Intraoperative Sphenoid Sinus Volume Measurement as an Alternative Technique to Intraoperative Computer Tomography.

Diagnostics (Basel) 2020 May 28;10(6). Epub 2020 May 28.

Radio Engineering Systems Department, Saint Petersburg Electrotechnical University "LETI", 197376 St Petersburg, Russia.

Isolated sphenoid sinus disease (ISSD) is where there is a group of pathologies characterized by inflammation in one or both sphenoid sinuses. Although computer tomography (CT)-based 3D reconstruction remains the gold standard among noninvasive approaches to ISSD diagnostics, no standardized techniques for direct intraoperative measurements of the sphenoid sinus volume in ISSD patients have been documented. We suggest a novel technique for the intraoperative measurement of the sphenoid sinus volume. Read More

Fungal Pneumonia in The Immunocompetent Host: A Possible Statistical Connection Between Allergic Fungal Sinusitis with Polyposis and Recurrent Pulmonary Infection Detected by Gastroesophageal Reflux Disease Scintigraphy.

Mol Imaging Radionucl Ther 2020 Apr;29(2):72-78

University of Notre Dame, CNI Molecular Imaging, Sydney, Australia.

Objectives: Fungal pneumonia in the immune competent host is a rarity with few reported cases in the literature. We present a series of 7 cases of recurrent fungal pneumonia in association with allergic fungal rhinosinusitis and gastroesophageal reflux disease (GERD). We hypothesised that recurrent infection may have been transported from the infected paranasal sinuses into the lung by GERD as the process was terminated by surgical fundoplication in 2 of these patients.

COVID-19 and ENT Surgery.

Eur Ann Otorhinolaryngol Head Neck Dis 2020 May 23;137(3):161-166. Epub 2020 Apr 23.

Department of Otorhinolaryngology, Head and Neck Surgery, Tours University Hospital, Tours, France. Electronic address:

In Otorhinolaryngology - Head and Neck Surgery, clinical examination and invasive procedures on the respiratory tract and on airway-connected cavities, such as paranasal sinuses and the middle ear, expose people to direct transmission of SARS-CoV-2 by inhalation or ocular projection of contaminated droplets, and to indirect transmission by contact with contaminated hands, objects or surfaces. Estimating an R of COVID-19 at around 3 justified postponing non-urgent face-to-face consultations and expanding the use of teleconsultation in order to limit the risks of SARS-CoV-2 infection of patients or health workers and comply with the lockdown. The health authority recommends cancellation of all medical or surgical activities, which are not urgent as long as this does not involve a loss of chance for the patient. Read More

Ophthalmic and orbital considerations in the evaluation of skull base malignancies.

J Neurooncol 2020 May 2. Epub 2020 May 2.

Division of Neurosurgical Ophthalmology, Pacific Neuroscience Institute, 2125 Arizona Ave, Santa Monica, CA, 90404, USA.

Introduction: The orbital contents, afferent and efferent visual pathways, and the cranial nerves involved in eye movement, corneal sensation and eyelid closure traverse the skull base, a region bounded by the intracranial cavity, the paranasal sinuses, and the deep spaces of the face and head. As such, tumors from above or below have potential to affect some aspect of the visual system.

Methods: We discuss here the clinical ophthalmologic and orbital considerations in the evaluation of patients with these tumors, as well as the ophthalmic sequelae of treatment with radiation or surgery (or both). Read More

A Rare Case of Sinonasal Malignant Melanoma - Local, Regional, and Distant Spread Accurately Detected by 18F Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography.

Indian J Nucl Med 2020 Apr-Jun;35(2):160-161. Epub 2020 Mar 12.

Department of Nuclear Medicine, All India Institute of Medical Sciences, New Delhi, India.

Melanomas are usually cutaneous in origin but rarely can also arise from the mucosal linings in the body. Sinonasal melanomas arise from the mucosa of the nasal cavity and paranasal sinuses, which account for approximately 50% of mucosal melanomas in the body. 18F fluorodeoxyglucose positron emission tomography-computed tomography (F-FDG PET/CT) has proven its role in malignant melanoma in staging especially in stage III and IV disease, restaging, assessing response to therapy and had affected in treatment change in significant number of cases.

Skull base surgery during the Covid-19 pandemic: The Italian skull base society recommendations.

Int Forum Allergy Rhinol 2020 Apr 29. Epub 2020 Apr 29.

Division of Maxillo-Facial Surgery, Department of Biomedical, Surgical and Dental Sciences, San Paolo Hospital, University of Milan, Milan, Italy.

Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), which causes coronavirus disease 2019 (Covid-19), is highly contagious with devastating impacts for healthcare systems worldwide. Medical staff are at high risk of viral contamination and it is imperative to know what personal protective equipment is appropriate for each situation. Furthermore, elective clinics and operations have been reduced in order to mobilize manpower to the acute specialties combatting the outbreak; appropriate differentiation between patients who require immediate care and those who can receive telephone consultation or whose treatment might viably be postponed is therefore crucial.

Utility of the Midface Degloving Approach for Extended Exposure in Maxillary Pathologies.

J Maxillofac Oral Surg 2020 Jun 18;19(2):217-224. Epub 2019 Sep 18.

Department of Oral and Maxillofacial Surgery, Meenakshi Ammal Dental College and General Hospital, Meenakshi Academy of Higher Education and Research (Deemed to be University), Alapakkam Main Road, Maduravoyal, Chennai 600095 India.

Introduction: A generous exposure of the midface region is essential for a comprehensive and thorough execution of midface surgical procedures, especially bilateral procedures. Traditional approaches to the midface the midface like the lateral rhinotomy and Weber-Fergusson/Dieffenbach incision with their modifications leave a visible scar, and they are limited in their unilateral exposure. The midface degloving approach with its exclusive intranasal and intraoral incisions leaves no external scars and lends excellent bilateral exposure of the maxilla, zygoma, paranasal areas and infraorbital margins from one side to the other.
