Background: To reduce recurrence rates of inverted papilloma (IP), some have argued for the use of intraoperative frozen margins; results remain mixed and studies critically lack lengthy surveillance periods.
Objective: We aim to elucidate the impact of prolonged surveillance and intraoperative frozen margins on IP recurrence.
Methods: This is a retrospective analysis of patients who underwent resection of IP at a tertiary care center over a 10-year period from 2008 to 2018 followed by subsequent surveillance.

Objectives: Postoperative pain medications and aspirin before undergoing functional endoscopic sinus surgery (FESS) are managed carefully due to concern for bleeding. Little is known regarding the increase in the risk of bleeding for patients unable to stop aspirin as trials are limited in this area. We compared outcomes for patients undergoing FESS who were managed postoperatively with nonsteroidal anti-inflammatory drugs (NSAIDs) versus opioids.

Prior studies have suggested activation of Ca signaling by pyocyanin in an airway cell line. Ca is tightly linked to both normal mitochondrial function as well as mitochondrial ROS and apoptosis during mitochondrial Ca overload.

Hops bitter β-acids lupulone and colupulone possess potent antibacterial activities and, as T2R1, T2R14, and/or T2R40 agonists, may improve the impaired mucociliary clearance described in CRS patients. We investigated these molecules as alternative treatments to antibiotics in CRS management based on their antibacterial and T2Rs agonists properties.

Given widespread exposure to the common cold coronavirus 229E (HCoV229E), we sought to investigate how HCoV-229E is cleared and stimulates interferon pathways in air-liquid interface (ALI) cultures from patients with CRSwNP.
Objective: The objective of this study was to identify whether viral clearance and ISG expression is different in ALI cultures from donors with CRSwNP compared with controls.

Objective: Undergoing surgery and adjuvant radiotherapy (aRT) at the same facility has been associated with higher overall survival (OS) in head and neck squamous cell carcinoma. Our study investigates whether undergoing surgery and aRT at the same academic facility is associated with higher OS compared with separate facilities in sinonasal squamous cell carcinoma (SNSCC).
Methods: The 2006 to 2017 National Cancer Database was queried for patients with SNSCC undergoing surgery at an academic facility followed by aRT with or without adjuvant chemotherapy.

Background: Non-hypothalamic glioneural hamartomas are rare entities known to cause medically refractory epilepsy. Olfactory bulb hamartomas, in particular, are exceptionally rare.
Methods: We describe a case of an olfactory bulb hamartoma that was surgically resected at our institution.
Inverted papilloma conversion to squamous cell carcinoma is not always easy to predict. AutoML requires much less technical knowledge and skill to use than traditional ML. AutoML surpassed the traditional ML algorithm in differentiating IP from IP-SCC.
View Article and Find Full Text PDFBackground: The inability of topical medications to reach sinus cavities is a potential reason for lack of efficacy in chronic rhinosinusitis (CRS). One purpose of endoscopic sinus surgery (ESS) is to enable delivery of medications into the sinus cavities. The exhalation delivery system with fluticasone (EDS-FLU; XHANCE) creates unique biomechanics that enable deposition of intranasal corticosteroid into sinuses and sinus drainage pathways but may have differing efficacy in operated versus unoperated sinuses.

We aimed to elucidate the natural history of postoperative QOL outcomes in IP patients treated with surgery.
Methods: Cases of sinonasal IP treated surgically at 4 tertiary academic rhinology centers were retrospectively reviewed.
Background: Empty nose syndrome (ENS) is a poorly understood, debilitating condition affecting a minority of patients who underwent nasal airway surgery, most commonly following inferior turbinate surgery. Few publications have demonstrated middle turbinate resection (MTR) causing ENS, but MTR is still considered a potential cause of ENS. The Empty Nose Syndrome 6-item Questionnaire (ENS6Q) is validated for ENS diagnosis, with ENS6Q ≥ 11 considered highly suggestive of ENS.

Odontogenic sinusitis (ODS) is a common cause of orbital, intracranial, and osseous infectious extrasinus complications. Dental infections can spread to the orbital or intracranial spaces though the sinuses via thrombophlebitis or direct extension, or from the dentition or oral cavity via vascular channels in the maxillary alveolar bone. ODS typically presents with unilateral involvement both clinically and radiographically.
View Article and Find Full Text PDFBackground: Sinonasal malignancy surveillance paradigms are often based on Head and Neck National Comprehensive Cancer Network guidelines, which do not recommend standard surveillance imaging beyond 6 months without concerning symptomatology or physical examination findings.
Methods: This was a retrospective analysis of all patients who underwent resection of sinonasal malignancy at a tertiary care center over a 20-year period from 2000 to 2020, with an ensuing surveillance period demonstrating recurrence.
Results: Fifty-two patients with sinonasal malignancy recurrence were included, with an average time to recurrence of 30.
The goal of this American Rhinologic Society expert practice statement (EPS) is to summarize the best available evidence regarding postoperative precautions for patients following endoscopic skull base surgery for intradural pathology. These topics include the administration of postoperative nasal hygiene; patient mobilization and activity level; the resumption of continuous positive airway pressure in patients with obstructive sleep apnea; and the timing and capacity with which a patient may be subjected to barotrauma, such as air travel postoperatively. This EPS was developed following the recommended methodology and approval process as previously outlined.

Background: Inverted papilloma (IP) is a benign tumor characterized by epithelial proliferation, which has the potential for malignant transformation. However, the mechanisms driving this transformation are poorly defined. Matrix metalloproteinase-11 (MMP-11), a regulator of the tumor microenvironment that degrades extracellular matrix, is upregulated in IP with dysplasia.

Akt is an important kinase in metabolism. Akt also phosphorylates and activates endothelial and neuronal nitric oxide (NO) synthases (eNOS and nNOS, respectively) expressed in M0 (unpolarized) macrophages. We showed that e/nNOS NO production downstream of bitter taste receptors enhances macrophage phagocytosis.

Because these tumors are rare, there are few studies that examine the specific QOL areas that are impacted. This knowledge would help improve the care of these patients.
