Sphenoid sinus lesions grasp the attention of Otorhinolaryngologists due to their prime location and vital surrounding structures. Once detected, these lesions require prompt investigation to identify the underlying cause, usually attributed to a tumor, fungal infection, sinusitis, or polyps, thus allowing tailored treatment. We report a case of an elderly lady whose neurological presentation lead to the diagnosis of sphenoid sinus lymphoma. We discuss the diagnostic challenge in view of its interesting presenting symptoms as well as the surgical approach risk and limitations.

Observational Study
COVID-19-associated rhino-orbital cerebral mucormycosis (ROCM) has a rapidly evolving course with high morbidity and mortality. We describe imaging features of COVID-19-associated ROCM based on noncontrast computed tomography (NCCT). This retrospective single-center observational study included 50 patients with COVID-19 from January 1, 2021 to June 30, 2021 who subsequently developed ROCM confirmed by fungal culture studies. All patients underwent NCCT of the paranasal sinuses as the diagnostic workup. The involvement of the nasal cavity, paranasal sinuses, orbits, and intracranial cavity was identified and graded. The ethmoid sinuses were most commonly involved [right (n = 46 of 50) > left (n = 45 of 50)], followed by the maxillary, sphenoid, and frontal sinuses. Thinning and erosions of the hard palate were noted in 18% of patients (n = 9), whereas 34% (n = 17) showed dehiscence of the lamina papyracea. Retromaxillary fat stranding was noted in 68% of patients (n = 34). Severe ethmoid sinusitis was associated significantly with ipsilateral pterygopalatine fossa involvement. The extraocular muscles were involved in 64% of patients (n = 32), with 84% (n = 42) showing orbital fat stranding. Proptosis of the affected eye was seen in 66% of patients, optic nerve involvement in 52%, and irregularity of globe contour in 12% (n = 6). The cavernous sinuses were affected in 10% of patients (n = 5), with three of them having temporal infarcts. COVID-19-associated ROCM is an acute, invasive fungal disease characterized by multisinus involvement, often with orbital and intracranial extension. Bilateral involvement with rapid progression should alert one to underlying COVID-19 disease.

OBJECTIVE
Functional endoscopic sinus surgery for chronic rhinosinusitis improves sinus drainage and intranasal medication delivery. This study compares medication delivery with commonly used devices in normal and altered anatomy (post functional endoscopic sinus surgery) using sinus surgery models (Phacon).
METHODS
Medication delivery was simulated via nasal drops, nasal spray and an irrigation device (Neilmed Sinus Rinse). Coverage was then calculated from endoscopic pictures taken at various anatomical sites in the normal nose and post functional endoscopic sinus surgery.
RESULTS
In the normal nose, nasal spray did not penetrate the sphenoid sinus, and drops bypassed the vestibule anteriorly. Neilmed Sinus Rinse provided superior coverage at the sphenoid site following sphenoidectomy and the frontal site following Draf III. After ethmoidectomy, nasal drops overall provided less coverage than the other methods.
CONCLUSION
Neilmed Sinus Rinse generally provided the best distribution, followed by the nasal spray and then nasal drops. The type and extent of surgery also affects medication delivery.

BACKGROUND
Loss of sense of smell is one of the most burdensome symptoms of chronic rhinosinusitis with nasal polyps (CRSwNP) but its relationship to sinus disease on imaging is unclear. Dupilumab improves sense of smell and radiographic severity of sinus disease in patients with CRSwNP. We investigated the relationship of sinus opacification severity and loci to olfactory impairment and dupilumab efficacy in patients with CRSwNP from the SINUS-24/SINUS-52 (NCT02912468/NCT02898454) studies.
METHODS
Sinus opacification was evaluated using the Lund-Mackay computed tomography (LMK-CT) score and sense of smell using patient-reported loss of smell (LoS) score, University of Pennsylvania Smell Identification Test (UPSIT) score and the 22-item Sino-Nasal Outcome Test (SNOT-22) smell/taste item.
RESULTS
At baseline, 95% of patients (688/724) had impaired sense of smell and opacification was extensive across all sinuses. Greater olfactory impairment was associated with greater opacification, especially in the ethmoid, sphenoid and frontal sinuses. At Week 24, reductions in LMK-CT total score and ethmoid and sphenoid sinus scores with dupilumab were weakly correlated with improvements in sense of smell assessed by LoS, UPSIT and SNOT-22 smell/taste item. More dupilumab than placebo patients achieved clinically meaningful improvement in LMK-CT total score at Week 24 and Week 52.
CONCLUSION
Radiographic disease severity on imaging was associated with smell outcomes in this cohort. Opacification of the ethmoid, sphenoid and frontal sinuses was associated with severe smell loss. These data suggest that dupilumab effects on smell may be partly mediated through reduced sinus inflammation.

OBJECTIVES
For the treatment of chronic rhinosinusitis functional endoscopic sinus surgery is a well-established therapy with high initial success rates. However, a significant proportion of patients have persistent disease requiring revision surgery. To date, studies including data of large patient collectives are missing. In this study, we aimed to identify anatomic factors increasing the need for revision surgery in a large patient collective with chronic rhinosinusitis without nasal polyps.
METHODS
Data were collected retrospectively on patients with recurrent or persistent chronic rhinosinusitis without nasal polyps requiring revision surgery. The patients' symptomatology, endoscopic and radiographic findings were analyzed. Preoperatively, patients were evaluated with endoscopic examination of the nose and paranasal sinuses. In all individuals computed tomography of the sinuses was performed. Images were evaluated according to the Lund-Mackay system. Information was also collected intraoperatively.
RESULTS
253 patients were included. The most common anatomic factor was incomplete anterior ethmoidectomy (51%), followed by residual uncinated process (37%), middle turbinate lateralization (25%), incomplete posterior ethmoidectomy (20%), frontal recess scarring (19%), and middle meatal stenosis (9%). Other factors such as persistent sphenoid pathology was less frequent.
CONCLUSION
Iatrogenic causes with inadequate resection of obstructing structures seem to be a principal risk factor for recurrent chronic rhinosinusitis and the need for revision sinus surgery. Meticulous attention in the area of the ostiomeatal complex during surgery with ventilation of obstructed anatomy as well as avoidance of scarring and turbinate destabilization may reduce the failure rate after primary endoscopic sinus surgery.

Introduction Due to the variable degree of pneumatization, the shape and size of the sphenoid sinus are irregular. An endoscopic intranasal transsphenoidal approach is made in sphenoid sinus pathologies, sphenoid sinusitis, and sellar and parasellar diseases. A diagnostic approach to the sphenoid sinus is also done to get a better MRI scan of the pituitary. The present study aims to describe the variant types of sphenoid sinus, morphometry, anatomy, and relations of sphenoid sinus, which will be helpful to surgeons during an endoscopic approach to the sphenoid sinus. Materials and methods We studied 76 cadaveric sphenoid sinuses that were exposed by taking a sagittal section of 38 formalin-fixed cadaveric heads. After examining the inter-sphenoidal septum, it was removed to observe the inside aspect of the sphenoid sinus. Different dimensions of the sinus were noted down. The bulges inside the sinus due to neurovascular structures in relation to the sinus were observed. Results The most prominent type found was the sellar in 68.4% of cases preceded by the postsellar in 23.7% of cases. Presellar type of pneumatization was seen only in 7.9% of cases and the conchal type was absent. Intersphenoid septum was seen in 92,1% of cases, out of which 11.4% of septums were deficient on the posterior aspect. An internal carotid artery bulge in the sphenoid sinus was seen in 46% of cases. In 27.6% and 19.7% of sphenoid sinuses, bulging of the optic and vidian nerves, respectively, were seen. Some of these structures were dehiscent in the sphenoid sinus. Conclusions To get more space in the sphenoid sinus, the septa in the sinus are removed by surgeons, which may damage the walls of the sphenoid sinus. Knowledge of the relations of neurovascular structures with the sphenoid sinus will be helpful to surgeons during the transsphenoidal endoscopic approach to avoid any injury to these structures.

PURPOSE
Worldwide, the incidence of chronic fungal rhinosinusitis (CFRS) has increased. Although ageing leads to weakening of the immune system, which increases susceptibility to CFRS, the CFRS characteristics in geriatric patients are unclear. Therefore, we comparatively analysed the clinical characteristics of CFRS in geriatric and non-geriatric patients.
METHODS
This retrospective analysis compared the demographics, rhinologic symptoms, multiple allergen simultaneous tests, olfactory function tests, paranasal sinus computed tomography findings, and outcomes of 131 patients with CFRS who underwent functional endoscopic sinus surgery and 131 enrolled patients were divided in geriatric (> 65 years) and non-geriatric (≤ 65 years) groups.
RESULTS
Among the geriatric and non-geriatric participants (n = 65, 49.6% and n = 66, 50.4%, respectively), hypertension and diabetes mellitus were more common in the geriatric group. Demographics, including symptoms, showed no significant intergroup differences. Normosmia and hyposmia were significantly less prevalent, whereas phantosmia and parosmia were more prevalent in the geriatric group than in the non-geriatric group (p = 0.03 and p = 0.01, respectively). Sphenoidal sinus involvement was significantly higher in geriatric patients than in non-geriatric patients (p = 0.02).
CONCLUSION
Based on greater sphenoidal sinus involvement, a deeper anatomical area is more vulnerable to fungal infection in the geriatric group than in the non-geriatric group. Increasing clinicians' awareness of CFRS in geriatric patients with olfactory dysfunction, including phantosmia and parosmia, is important for early intervention.

Cavernous sinus thrombosis (CST) is a rare but life-threatening infectious disease whose diagnosis and treatment are challenging. CST can result in ocular and neurologic morbidities, as well as fatal systemic complications due to systemic thrombus. Occasionally, these clinical symptoms can be a result of contralateral sinusitis. A 75-year-old female presented with severe headache and fever. Magnetic resonance imaging revealed a multifocal filling defect in both cavernous sinuses, with heterogeneous enhancement and thrombosis of the right superior ophthalmic vein. Intravenous antibiotic was administered, and endoscopic sinus surgery was performed. The patient was discharged 40 days after admission and there were no neurologic symptoms and no evidence of sequelae during the 10-month follow-up. Symptoms of CST on the contralateral side are often missed, which delays initiation of appropriate treatment. When CST secondary to paranasal sinusitis is diagnosed, clinicians should consider contralateral as well as ipsilateral infection of the paranasal sinus. Preventing disease progression and complications through early and aggressive antibiotic administration along with sinus surgery is crucial.

Chronic rhinosinusitis (CRS) is a widespread disease with various symptoms. It is defined as an inflammation of the nasal mucosa and paranasal sinuses lasting for 12 weeks, with symptoms of nasal obstruction and/or congestion and facial pain and/or pressure as well as decreased sense of smell. Despite the widespread prevalence of the disease, the diagnosis and treatment of CRS are still not adequately developed, so many patients remain misdiagnosed. This study involved 150 patients who, according to EPOS guidelines, met the diagnosis of CRS without nasal polyposis. Each patient underwent a computerized tomography (CT) scan of the paranasal sinuses, which was evaluated according to the Lund-Mackay scoring system. Furthermore, patients completed a visual analog scale (VAS) score questionnaire which examined the severity of their symptoms. The aim of this study was to find an association between the degree of mucositis and the clinical symptoms reported by the patient. Our results showed a low positive correlation between nasal secretion and Lund-Mackay score for the bilateral ostiomeatal complex (OMC). Furthermore, a low positive correlation was found between the severity of reduced sense of smell and severity of anterior ethmoid and sphenoid sinusitis. The results demonstrated a low negative correlation between the severity of facial pain or pressure and the severity of inflammation of the anterior ethmoid and sphenoid sinus. The results of statistical testing did not show statistical differences in severity of subjective symptoms for almost all of the observed symptoms in persons with unilateral inflammation and persons without unilateral inflammation, except for cough. People who did not have unilateral inflammation had a more pronounced cough compared with people who had unilateral inflammation. However, these correlations were very mild and not clinically significant, so we cannot say that the distribution of sinusitis significantly affects the occurrence of characteristic symptoms in chronic rhinosinusitis.
