Abstract

We report the rare occurrence of bilateral asymmetrical mucoceles of the paranasal sinuses that resulted in a unilateral orbital complication. The patient was a 47-year-old woman who presented with complaints of diplopia, blurred vision, and protrusion of her right eye that had progressed over a period of several months following an upper respiratory tract infection. Computed tomography detected the presence of two large, asymmetrical mucoceles. The lesion on the right involved the frontal and ethmoid sinuses, and the one on the left involved the ethmoid sinus. The mucoceles were locally expansile and had eroded the surrounding bony structures on the right. The expansile nature of the right-sided mass had displaced the right orbit, which was the cause of the vision deterioration. Transnasal endoscopic surgery was performed to excise and marsupialize the mucoceles. This modality was preferred over conventional open surgery because it affords good visualization, it is safe, and it is a less morbid procedure. The patient's recovery was uneventful, and she was discharged home on the third postoperative day. On continuing follow-up, her vision had improved, her intraocular pressure had returned to normal, and her orbits were in their normal position. Based on our literature search, no case of bilateral frontal and ethmoid sinus mucoceles has been previously reported.

Hemangioma of a posterior ethmoid sinus: Report of a rare case

Abstract

Very few cases of hemangioma of the ethmoid sinuses have been reported in the literature. These lesions can be difficult to diagnose in the paranasal sinuses because obtaining an adequate biopsy specimen can be dangerous in view of the potential for profuse bleeding. We report a case of a cavernous hemangioma in the right posterior ethmoid sinus of a 45-year-old man. The mass was excised in its entirety.

Verrucous carcinoma of the paranasal sinuses: A case report

article

Abstract

Verrucous carcinoma is a low-grade variant of squamous cell carcinoma reported to occur in all anatomic sites in the head and neck region, most commonly the oral cavity. The tumor grows locally invasive but is histologically benign and metastasizes rarely. To date, 22 cases of verrucous carcinoma involving the nasal cavity and/or the paranasal sinuses have been reported. We present a case of verrucous carcinoma involving the paranasal sinuses, nasal cavity, cranium, and orbit. This case highlights the difficulty of pathologic diagnosis and management options for a rare neoplastic lesion.

Ecthyma gangrenosum mimicking acute invasive fungal sinusitis in an immunocompromised patient

article

Abstract

Ecthyma gangrenosum is a rare necrotizing cutaneous infection usually caused by Pseudomonas aeruginosa. We report a case of ecthyma gangrenosum presenting as a sinonasal eschar and mimicking acute invasive fungal sinusitis in an immunocompromised 39-year-old man with a hematologic malignancy. To the best of our knowledge, this represents the first case of ecthyma gangrenosum affecting the sinonasal mucosa to be reported in the literature.

One-year results: Transantral balloon dilation of the ethmoid infundibulum

article

Abstract

A prospective, multicenter research study is under way to demonstrate long-term improvement in chronic rhinosinusitis symptoms after transantral balloon dilation of the ethmoid infundibulum. Trial results from an interim analysis of symptomatic status using the Sino-Nasal Outcome Test 20 survey demonstrate significant and sustained improvement through post-procedure 1-year follow-up. Additionally, these data provide evidence that the symptomatic improvements following balloon expansion within the ostiomeatal unit to treat medically refractory inflammation of the maxillary sinuses, either alone or with concomitant anterior ethmoid disease, are similar.
