1/77. Huge hamartoma with inverted papilloma in the nasal cavity.We report clinical experience in managing a 46-year-old Japanese man with long-standing nasal obstruction resulting from a huge left nasal mass. Computed tomography, magnetic resonance imaging and biopsy were used to make a provisional diagnosis of inverted papilloma. The mass was resected via a frontal approach combined with rhinotomy. Histopathologic examination of the resected specimen was consistent with a hamartoma that included an inverted papilloma on a portion of its surface. In addition to being rare tumors in the nasal cavity, we believe that our patient's tumor the largest nasal hamartoma ever reported.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
2/77. Rhinocerebral mucormycosis: a case of a rare, but deadly disease.Rhinocerebral mucormycosis is a rare fungal infection of the nasal cavity and sinuses that can spread to the orbits and cranium within days. Its presentation can be confused with those of sinusitis, viral infections, diabetic ketoacidosis, or carotid sinus thrombosis, and it is often missed at early presentation. survival is directly linked to early detection and treatment. We present a case of rhinocerebral mucormycosis and discuss the literature on its early signs and symptoms, pathophysiology, and treatment options.- - - - - - - - - - ranking = 0.2keywords = cavity (Clic here for more details about this article) |
3/77. Surgical technique for reconstruction of the nasal septum: the pericranial flap.BACKGROUND: We describe a new technique for the surgical reconstruction of large-sized anterior septal perforations based on the pericranial flap. methods: The technique requires a standard open rhinoplasty combined with a pericranial flap harvested after a bicoronal approach and tunnelled to the nasal cavity. We present the case of a man with complete destruction of the nasal septum as a result of chronic cocaine abuse. RESULTS: Surgery resulted in a permanent and complete closure of the perforation. CONCLUSIONS: The main advantage of this technique is the use of well-vascularized autogenous tissue and the minimal donor site morbidity. This technique provides a new method to close large nasal perforations.- - - - - - - - - - ranking = 0.2keywords = cavity (Clic here for more details about this article) |

5/77. A rare case of upper airway obstruction in an infant caused by basal encephalocele complicating facial midline deformity.A four-month-old male infant with basal encephalocele of the transsphenoidal type presented with upper airway obstruction and facial midline deformity, including cleft lip, cleft palate, hypertelorism and exophthalmos. Basal encephalocele is a rare disease, and usually not detectable from the outside. In this case, initially the cause of an upper airway obstruction was considered to be posterior rhinostenosis, and posterior rhinoplasty with inferior nasal conchectomy was scheduled. However, in preoperative examination, computed tomography (CT) and magnetic resonance imaging (MRI) revealed a bony defect in the sphenoidal bone and a cystic mass in communication with cerebrospinal fluid, herniating into the nasal cavity through the bony defect. The mass was diagnosed as a transsphenoidal encephalocele, the scheduled operation cancelled, and tracheostomy performed for airway management. The possibility of basal encephalocele should be considered in the case of upper airway obstruction with facial midline deformity.- - - - - - - - - - ranking = 0.2keywords = cavity (Clic here for more details about this article) |
6/77. mucormycosis of the nose and paranasal sinuses.Rhinocerebral mucormycosis is an invasive fungal infection initiated in the paranasal sinuses that frequently progresses to orbital and brain involvement. If recognized early, involvement is limited to the nasal cavity and paranasal sinuses. Diabetics in poor control are at greatest risk, however, any immunocompromised individual may be infected. The mainstays of therapy are reversal of immunosuppression, systemic amphortericin B, and surgical debridement. survival has improved dramatically, yet deaths still occur if the infection is not recognized and not treated early in its course or if the source of immunocompromise is not reversible. Several case examples illustrate the clinical course of this unusual, but potentially fatal, fungal infection. Taxonomy, clinical presentation, diagnosis, and management of mucormycosis of the paranasal sinuses are reviewed in detail.- - - - - - - - - - ranking = 0.2keywords = cavity (Clic here for more details about this article) |
7/77. Juvenile xanthogranuloma of the nasal cavity.Juvenile xanthogranuloma is a benign, normolipaemic, self-healing condition and a type of histiocytosis that occurs most frequently in infants and children. This condition usually presents with solitary or multiple cutaneous lesions and occasionally with visceral lesions. We report a case of juvenile xanthogranuloma occurring in the nasal cavity. We believe this is the first report, in the English literature, of juvenile xanthogranuloma occurring in this site.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
8/77. Pyogenic granuloma (pregnancy tumor) of the nasal cavity. A case report.BACKGROUND: Pyogenic granuloma is a benign lesion of unknown etiology that occurs in the skin and mucous membranes. It has been reported as a common lesion of the oral cavity and, less commonly, the nasal cavity. Although its etiology is unclear, pyogenic granuloma has long been associated with pregnancy, oral contraceptives and trauma. The term pregnancy tumor has been used to reflect the association with pregnancy; nevertheless, pyogenic granuloma is often misdiagnosed in obstetric patients. CASE: We present the case of a 37-year-old, pregnant woman with an enlarging nasal mass ultimately diagnosed as pyogenic granuloma. The patient was treated successfully with endoscopic excision of the lesion. CONCLUSION: Pyogenic granuloma is a rapidly growing lesion that should be considered in the differential diagnosis of any gravid patient with a mass in the oral or nasal cavity. The lesion may result in complications of the pregnancy, and management should be individualized for each patient.- - - - - - - - - - ranking = 1.4856970286682keywords = cavity, oral cavity (Clic here for more details about this article) |
9/77. Nasal fistula associated with dental infection: a report of a case.Most clinicians have come across a patient with difficult symptoms to diagnose. Often confusion occurs between odontogenic and nonodontogenic causes of sinus discomfort. On many occasions, sinus pain is due to purely dental causes, whereas in other situations dental pain is reported when the sinuses are infected. Due to the intimate association between the roots of the maxillary teeth and the floor of the nasal cavity and maxillary sinuses, diagnosis may be difficult. The following is a case report of a nasal fistula that developed from an abscessed maxillary central incisor.- - - - - - - - - - ranking = 0.2keywords = cavity (Clic here for more details about this article) |
10/77. Sinonasal tract eosinophilic angiocentric fibrosis. A report of three cases.Eosinophilic angiocentric fibrosis (EAF) is a rare submucosal fibrosis without a well-developed differential diagnosis. Three cases of sinonasal tract EAF were identified in 2 women and 1 man, aged 49, 64, and 28 years, respectively. The patients experienced a nasal cavity mass, maxillary pain, or nasal obstructive symptoms of long duration. The process involved the nasal septum (n = 2), nasal cavity (n = 1), and/or the maxillary sinus (n = 1). There was no evidence for wegener granulomatosis, churg-strauss syndrome, Kimura disease, granuloma faciale, or erythema elevatum diutinum. Histologically, the lesions demonstrated a characteristic perivascular "onion-skin" fibrosis and a full spectrum of inflammatory cells, although eosinophils predominated. necrosis and foreign body-type giant cells were not identified. Surgical excision was used for all patients, who are all alive but with disease at last follow-up. Sinonasal tract EAF is a unique fibroproliferative disorder that does not seem to have systemic associations with known diseases. The characteristic histomorphologic features permit accurate diagnosis.- - - - - - - - - - ranking = 0.4keywords = cavity (Clic here for more details about this article) |
