Small cell neuroendocrine carcinoma of the paranasal sinuses is an extremely rare and aggressive neoplasm. Despite aggressive management, the tumor carries a poor prognosis, with a high risk of local recurrence or distant metastases. The management strategy is based on that for pulmonary small cell cancer and includes platinum-based chemotherapy combined with radiotherapy. We are reporting a ca...

The paranasal sinuses and the mastoid air-cell systems are evaginations of the mucous membrane of the nasal and nasopharyngeal cavities . Separate theories regarding their pneumatization have been suggested. However, correlation studies between the two systems giving a possible clue to a common pneumatizing process have been few (1 , 2]. One hundred adult patients without ear disease and minima...

Agenesis of paranasal sinuses has only been described in case reports of patients with primary ciliary dyskinesia (PCD). As agenesis of paranasal sinuses may contribute to low nasal nitric oxide levels, a common finding in PCD, we speculated that this condition might frequently occur in PCD patients. Patients referred for PCD evaluation were consecutively recruited for 30 months. In addition to...

Background Precise knowledge of anatomic variations of nose and paranasal sinus complex is essential for achieving best surgical results during endoscopic sinus surgery. Computed tomography is the gold standard investigation for evaluation of paranasal sinuses and adjacent structures. Objective To study prevalence of anatomical variations of nose, paranasal sinuses and osteomeatal complex and t...

objectives: new digital two-dimensional imaging systems are considered as an easily accessible modality for sinonasal evaluation. the aim of this study was to assess the diagnostic efficacy of digital waters’ and caldwell’s radiographic views for evaluation of sinonasal area. materials and methods: a total of 273 patients fulfilling the inclusion criteria were enrolled in this descriptive-analy...

ROCM is the most common type of Mucormycosis and it can rapidly spread from paranasal sinuses to orbit brain which be fatal in patients. Diabetes mellitus risk factor India. As invasive fungal diseases present with nonspecific clinical features, increasing awareness education among clinicians about this deadly enemy very crucial for early diagnosis prompt initiation appropriate therapy. We are ...

Adenocarcinomas of various types comprise 10 to 20% of all primary malignant neoplasms of the nasal cavity and paranasal sinuses. They are thought to originate from seromucous glands of the nasal cavity and paranasal sinuses as well as the surface epithelium. Long-term prognosis is poor and patients usually die due to local spread with no metastasis. This clinical report describes a method for ...
