BACKGROUND: Inadvertent lateralization of the middle turbinate (MT) after endoscopic sinus surgery (ESS) is cited as a common complication that results in both outflow tract obstruction and recurrent symptoms. In endoscopic endonasal skull-base surgery, the MT is frequently lateralized during the parasagittal approach. Little is known about whether this strategy has unintended consequences on the adjacent paranasal sinuses. Intentional lateralization vs surgical resection of the MT were compared for radiographic evidence of sinus obstruction in this patient population...

Fibrous dysplasia is a slow growing fibro-osseous tumor, which is infrequent in craniofacial location and very rarely found in paranasal sinuses. Its occurrence is usually in children and young adolescents. The complications common in this location are related to the sinus ostia obstruction, like sinusitis or mucocele formation. Aneurysmal bone cyst formation has also been reported. We present a case of frontoethmoid fibrous dysplasia which extends to the nasal cavity and extraaxial frontal region. The peculiarity about the case is its association with the intradiploic CSF cyst formation, which to best of our knowledge has never been reported before...

Schwannomas (neurinomas) are benign, encapsulated, and slow-growing neoplasms developing from any peripheral, cranial, or vegetative nerve that has the Schwann sheath. Schwannomas of the nasal cavity and paranasal sinuses in adults occur rarely, less than 4% of cases. The world literature lacks similar data for the pediatric age group because these tumors in children are unique and extremely rare. The most common clinical symptoms of sinonasal schwannoma are nasal breathing disorders, hyposmia or anosmia, and snoring at night...

Metastasis from distant primary tumors is extremely rare in the paranasal sinuses with few hundred cases in the literature. Metastatic carcinoma of the prostate is even rarer, despite being one of the most common tumors, with only 24 cases published. In this article, we report a case of a 58-year-old male presenting with epistaxis and nasal obstruction as initial symptoms of a metastatic prostate carcinoma in the ethmoid cells and maxillary sinus.

The World Health Organization (WHO) 2017 classification of head and neck tumors has been just published and has reorganized tumors of the nasal cavity and paranasal sinuses. In this classification, three new entities (seromucinous hamartoma, NUT carcinoma, and biphenotypic sinonasal sarcoma) were included, while the total number of tumors has been reduced by excluding tumors if they did not occur exclusively or predominantly in this region. Among these entities, benign tumors were classified as sinonasal papillomas, respiratory epithelial lesions, salivary gland tumors, benign soft tissue tumors, or other tumors...

BACKGROUND: Paranasal sinus osteoma is a common, asymptomatic, histologically benign, and slow-growing tumor. However, it can give rise to secondary pathologies such as a mucocele in about 50% of the cases. Rarely, intracranial and orbital extension is present leading to rhinoliquorrhea, pneumocephalus, or neurological and visual impairment, which might be potentially life-threatening. CASE DESCRIPTION: A 49-year old man presented with an acute frontal lobe syndrome and rhinoliquorrhea...

BACKGROUND: With the exception of osteomas, bone neoplasms that originate in the sinonasal cavity are seldom diagnosed on preoperative imaging due to a lack of characteristic radiographic features. Here we described the unusual occurrence of an osteoblastoma in the paranasal sinuses, and we drew focus to its salient imaging features. A highly unique imaging sign was indicated, and its pathologic basis was explained, with concurrent review of the literature. METHODS: Case series and review of the literature...

INTRODUCTION: Ewing sarcoma (ES) of the sinonasal tract and associated primitive neuroectodermal tumors are rare. To our knowledge, only 10 case reports of sinonasal ES of the nose or paranasal sinuses have been reported. Furthermore, there has been only 1 case of sinonasal ES arising from the middle turbinate. Recommended management of sinonasal ES stems from the management of its osseous counterpart, ES, but treatment with surgery, radiotherapy, and chemotherapy is varied. Five-year survival rates vary from 21% to 70%, with the lower rates representing patients presenting with metastatic disease...

Non-Hodgkin's lymphoma (NHL) is a lymphatic system tumor originating from either B or T lymphocytes and shows a high malignant potential. In HIV-seropositive patients, NHL of head and neck is mainly found in Waldeyer's ring, oral mucosa, salivary glands, paranasal sinuses, and laryngeal tissue. Primary NHL rarely affects the bone. When the lesion affects the bones of the jaws, it is rare in the mandible when compared to the maxilla. In the reported cases, only 0.6% are found in the mandible. NHL of the mandible can be difficult to diagnose, and so the prime aim of the present case report is to establish appropriate diagnosis of one of such kinds...

Avian influenza A(H7N9) virus infections frequently lead to acute respiratory distress syndrome and death in humans. We aimed to investigate whether primary cultures of human respiratory tract epithelial cells are helpful to understand H7N9 virus pathogenesis and tissue tropism, and to evaluate how patient-related characteristics can affect the host's response to infection. Normal human bronchial epithelial cells (isolated from two different donors) and primary epithelial cells (harvested from 27 patients undergoing airway surgery) were experimentally infected with H7N9 and/or H1N1pdm for 72 h...
