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.

68Ga-PSMA PET/CT Scan on Postoperative Assessment of Sinonasal Glomangiopericytoma.

Clin Nucl Med 2021 Apr 5. Epub 2021 Apr 5.

From the Departments of Otorhinolaryngology & Head and Neck Surgery Nuclear Medicine, All India Institute of Medical Sciences, New Delhi, India.

Abstract: Prostate-specific membrane antigen (PSMA) is expressed on the endothelial cells of tumor-associated neovasculature of various nonprostatic benign and malignant neoplasms. Positive intense uptake on PET/CT imaging with 68Ga-labeled PSMA is noted in a patient with sinonasal glomangiopericytoma, and the same is noted to be absent following complete surgical excision. 68Ga-PSMA PET/CT may be a useful tool for early recurrence identification, differentiating recurrence from surgical site reparative tissues, and peptide receptor radionuclide therapy of residual lesions.

The Endonasal Endoscopic Management of Cerebrospinal Fluid Rhinorrhea.

Cureus 2021 Feb 20;13(2):e13457. Epub 2021 Feb 20.

Otolaryngology - Head and Neck Surgery, King Fahad Specialist Hospital, Dammam, SAU.

Introduction Cerebrospinal fluid (CSF) rhinorrhea is the result of a bony defect at the skull base with disruption of the arachnoid, dura mater, and sinonasal mucosa that leads to an active CSF leak and flow of clear fluid from the nose. The endoscopic repair of CSF leaks and skull defects have been used by an increasing number of surgeons and is the standard of care for repairing CSF leaks. Materials and methods We conducted a retrospective study of all cases of CSF leaks managed via the endonasal endoscopic approach from 2010 to 2020 at a tertiary referral hospital of King Fahad Specialist Hospital, Dammam (KFSH-D).
