1/87. mucocele in an orbitoethmoidal (Haller's) cell (accidentally combined with acute contralateral dacryocystitis).Haller's cells--according to recent terminology now called orbitoethmoidal cells (OEC)--are defined as anterior or posterior ethmoidal cells that have developed into the orbital floor. They can be excessively pneumatized and thus contribute to obstruction of the ostiomeatal complex area. We present the case of a 42 year old white male, who was admitted for treatment of an acute dacryocystitis on the right side. The CT scan revealed moderate sinusitis of the right ethmoid and maxillary sinuses and coincidentally a mucocele in an OEC on the left side. An endoscopic dacryocystorhinostomy on the right and a revision of the mucocele on the left side were performed in the same sitting. We consider both indications--stenosis of the nasolacrimal duct as well as mucoceles rewarding indications for endoscopic surgery. An external approach to the nasolacrimal duct in this case would have been problematic, as the external skin and soft tissue covering the duct already showed severe inflammatory changes. The operation of the up until that time asymptomatic mucocele was of prophylactic character. To our knowledge this is the first report of a mucocele developing in an OEC in the literature.- - - - - - - - - - ranking = 1keywords = sinusitis (Clic here for more details about this article) |
2/87. Isolated intracranial mucocele.Intracranial mucoceles have been previously reported as direct extradural extensions of mucoceles of the paranasal sinuses. We describe a patient with 2 silent mucoceles isolated within the parenchyma of the frontal lobe of the brain. The patient had undergone multiple previous intranasal polypectomy and ethmoidectomy procedures, and the unsuspected mucoceles were discovered on a computed tomographic scan obtained to evaluate recurrent rhinosinusitis symptoms. craniotomy was required for removal of the mucoceles.- - - - - - - - - - ranking = 3.2735027574548keywords = frontal, sinusitis (Clic here for more details about this article) |
3/87. Intracranial mucocele as a complication of endoscopic repair of cerebrospinal fluid rhinorrhea: case report.OBJECTIVE AND IMPORTANCE: Endoscopic repair of an anterior cranial fossa cerebrospinal fluid (CSF) fistula has gained widespread acceptance. We report a case of mucocele development at the site of an endoscopic CSF leak repair. CLINICAL PRESENTATION: A 46-year-old woman underwent functional endoscopic sinus surgery for nasal obstructive symptoms. The surgery was complicated by an intraoperative CSF leak from the posterior cribriform plate/anterior sphenoid, which was repaired immediately using bone and mucosa grafts. Two years postoperatively, a 13-mm anterior cranial base mass was found incidentally. This mass increased to 20 mm over the next year. INTERVENTION: The anterior cranial base mass was excised via a right frontal craniotomy and confirmed histologically to be a mucocele. CONCLUSION: Endoscopic repair of an anterior cranial base CSF fistula with mucosal grafts may lead to formation of a mucocele.- - - - - - - - - - ranking = 2.2735027574548keywords = frontal (Clic here for more details about this article) |
4/87. Frontal mucocele presenting as a subcutaneous tumour on the forehead.A 57-year-old Japanese woman had a 3-month history of an asymptomatic subcutaneous tumour on the forehead. The patient presented a slightly elevated, elastic soft subcutaneous mass, 3 cm in diameter, on the mid to left-side forehead. Slight swelling of the left upper eyelid was observed. CT scanning and magnetic resonance images revealed a sharply demarcated cystic mass from the subcutaneous area on the forehead expanding into the frontal sinus and intracranial space. The tumour was diagnosed as a frontal mucocele and combined external and endoscopic approaches were performed. It is rare that a patient with a frontal mucocele is initially referred as a case of a subcutaneous tumour because most of the patients complain primarily of the ophthalmic symptoms. However, the present case reminds us that frontal mucocele is one of the differential diagnoses for a subcutaneous mass on the forehead.- - - - - - - - - - ranking = 9.0940110298191keywords = frontal (Clic here for more details about this article) |
5/87. Mucocoeles of the maxillary sinus.Mucocoeles of the paranasal sinuses most commonly occur in the frontal or anterior ethmoidal sinuses. We report two rare cases of mucocoele of the maxillary sinus and describe the presentation, investigations and treatment. A review of the literature on this rare clinical entity is included, with specific reference to diagnostic imaging to distinguish mucocoeles from neoplastic sinus disease.- - - - - - - - - - ranking = 2.2735027574548keywords = frontal (Clic here for more details about this article) |
6/87. A giant intracranial mucocele associated with an orbitoethmoidal osteoma. Case report.The authors present a rare case of a giant intracranial mucocele associated with an orbitoethmoidal osteoma in a patient suffering from a generalized convulsive disorder. The broad pedicle of the osteoma had penetrated the cribriform plate and extended intracranially to form a nodular mass in the olfactory groove. The intracranial portion of the osteoma was surrounded by a mucocele. Both the cyst wall and multilayered intracystic septations of the mucocele were indented by layers of the osteoma. Although the extracranial portion adhered to the mucosa of the ethmoidal sinus, there were no signs of sinus obstruction. No direct communication other than the osteoma was identified between the mucocele and the ethmoidal mucosa. The large cerebral defect, which the mucocele occupied, communicated directly with the lateral ventricle without any intervening membranous structures. A frontal craniotomy is recommended for exposure of the lesion and plastic repair of the dural defect.- - - - - - - - - - ranking = 2.2735027574548keywords = frontal (Clic here for more details about this article) |
7/87. The endoscopic management of chronic frontal sinusitis associated with frontal sinus posterior table erosion.Expansile inflammatory diseases of the frontal sinuses may produce erosion of the posterior table of the frontal sinus. In these instances, the bone between sinus mucosa and intracranial dura is absent. Over the past decade, endoscopic frontal sinusotomy has emerged as the preferred technique for the treatment of refractory chronic frontal sinusitis. Endoscopic approaches also have a role in the most advanced instances of frontal sinusitis. A retrospective chart review of patients who were treated for frontal sinusitis with erosion of the frontal sinus posterior table was performed. Eight patients were identified. All patients underwent endoscopic frontal sinusotomy; some patients required multiple endoscopic procedures. Complete frontal recess dissection with identification of the frontal ostium was achieved for all involved frontal sinuses. In all cases, this postoperative result was monitored by CT scans (where indicated) and serial nasal endoscopy, which demonstrated good frontal sinus aeration and normal mucociliary clearance. Antibiotics were administered for culture-documented bacterial exacerbations, and systemic steroids were given for management of allergic fungal sinusitis and sinonasal polyposis associated with asthma. No patient underwent frontal sinus obliteration or cranialization. No suppurative intracranial complications were noted during the postoperative period. Endoscopic frontal sinusotomy can be used safely for the definitive management of frontal sinusitis associated with posterior table erosion. In fact, endoscopic techniques may represent the preferred approach for the treatment of this problem. Such an approach avoids the morbidity of more destructive alternatives (such as obliteration), and serves to create a frontal sinus with normal mucociliary clearance.- - - - - - - - - - ranking = 103.65187968324keywords = frontal sinusitis, frontal, sinusitis (Clic here for more details about this article) |
8/87. Maxillary antral mucocele and its relevance for maxillary sinus augmentation grafting: a case report.Paranasal sinus mucoceles are benign, locally expansile cyst-like masses that are filled with mucus and lined with epithelium. Most occur in the frontal sinus. maxillary sinus mucoceles are presumably uncommon in the united states and European countries, although they have been frequently reported in japan, particularly following Caldwell-Luc surgery. Clinical symptoms may not appear for at least 10 years postoperatively. Chronic sinus inflammation and allergic disease are also common causes of paranasal mucoceles. This paper provides an overview of maxillary sinus mucoceles and presents a case study involving a 62-year-old Latin male whose asymptomatic maxillary sinus mucocele was not revealed until he presented for maxillary sinus grafting and implant placement.- - - - - - - - - - ranking = 2.2735027574548keywords = frontal (Clic here for more details about this article) |
9/87. Primary non-Hodgkin's lymphoma of the frontal sinus: how we diagnosed it.Isolated primary non-Hodgkin's lymphoma of the frontal sinus is rare. We describe the case of a middle-aged man who came to us with signs of orbital cellulitis complicating an acute infected frontal mucocele. His condition was initially controlled with medical therapy and subsequent endoscopic sinus surgery, but his symptoms eventually returned. We were able to diagnose the lymphoma only by approaching the sinus externally to obtain a biopsy. This case highlights the importance of making a full visual inspection of the involved sinus in order to avoid missing an unexpected, albeit a rarely encountered, pathology.- - - - - - - - - - ranking = 13.641016544729keywords = frontal (Clic here for more details about this article) |
10/87. Intracranial spread of a giant frontal mucocele: case report.A giant mucocele eroded both the anterior and posterior wall of the frontal sinus and infiltrated the dura mater. Its extracranial growth caused a frontal bony prominence. The tumour and part of the dura were resected. A 12 x 6cm defect in the dura was repaired with a freeze-dried patch. A split-thickness bone graft from the right parietal region was used to repair the anterior frontal bony defect. The result one year later was satisfactory. Spiral computed tomography with thr ee-dimensional reconstructions excluded any recurrence of the tumour and showed good integration of bone grafts.- - - - - - - - - - ranking = 15.914519302183keywords = frontal (Clic here for more details about this article) |
