Some sinonasal microanatomic variations can leads to chronic sinusitis. These variations are most commonly in middle meatus and narrow the ostiumeatal unit. In this study, we compared microanatomic variations of lateral nasal wall and sinuses between normal cadavers and patients with chronic sinusitis. This comparative-descriptive study was conducted between 50 sinonasal complexes. The results ...
Changes in imaging sinonasal inflammatory disease have paralleled changes in the treatment of chronic sinusitis. As functional endoscopic sinus surgery has become a more widespread technique, coronal computed tomography (CT) has become the primary imaging modality, replacing plain radiography. Knowledge of the plethora of sinonasal anatomic variations and the inherent surgical implications is c...
Sinonasal foreign bodies are rare clinical entities. Their presence in the sinuses can originate complications, so their removal is always indicated. We present 3 cases of sinonasal foreign body, indicating their symptoms, imaging findings and surgical removal. Each patient was assessed with computerized tomography of the sinuses, rigid endoscopy, and then surgical removal. We confirmed the pre...
Sinonasal melanoma is a rare disease with limited data regarding its optimal treatment. It is an aggressive disease with up to 60% of patients developing local recurrence or distant metastases in the first 24 months after treatment. We report a case of sinonasal melanoma involving the skull base which was treated by endoscopic anterior craniofacial resection together with brachytherapy postoper...
We present a case of odontogenic maxillary sinusitis whose sinonasal symptomatology was thought to be the consequence of a previous midfacial trauma. The patient was admitted to the Clinic of Oral and Maxillofacial Surgery after more than 10 years of exacerbations of sinonasal symptoms, which began to plague soon after a facial contusion. We decided to perform CT of paranasal sinuses, and despi...
Sinonasal hemangiomas, although rare, must be considered in the evaluation of intranasal masses with profuse epistaxis. Although the availability of literature discussing cavernous hemangiomas in this location is limited, there have been no case reports of exclusively soft tissue sinonasal cavernous hemangiomas extending to the anterior skull base (ASB) that were resected purely endoscopically....
Invasive fungal infections of the sinonasal tract are a rare but known entity in immunocompromised patients. Paecilomyces lilacinus is a nematophagous fungi with septate hyphae that has afflicted humans in multiple forms, causing cutaneous, ocular, and sinonasal infections. Only 4 cases of P lilacinus and 2 cases of Paecilomyces variotii in the sinonasal tract have been reported in the literatu...
Background & objective: Hemangiopericytoma is an uncommon vascular tumor derived from the pericytes of Zimmermann. . The most common location of the tumor is pelvic retroperitoneum and musculoskeletal system of the lower extremities. It is rarely seen in the head and neck area. In addition, only 0.8% to 3% of all orbital tumors and less than 5 % of primary sinonasal tumors are primary hemangiop...
INTRODUCTION Modern advances in endonasal endoscopic surgery have expanded its utility in the management of malignant sinonasal tumours, and the degree to which cases are eligible. Knowledge of the indications, inclusion and exclusion criteria and imaging workup that empowers judicious patient selection is essential. This article discusses the endoscopic resection of malignant sinonasal tumours...
Glomangiopericytoma/sinonasal type hemangiopericytoma is a rare sinonasal neoplasm arising from the pericytes surrounding capillaries and accounts for less than 0.5% of all sinonasal tumors. This tumor differs from conventional soft tissue hemangiopericytoma in location, biologic behaviour and histologic features. Glomangiopericytoma is a borderline low malignancy tumor with a good prognosis af...
