If the tumor is very vascular or assessed and, if necessary, biopsies or frozen sections of the frm then it can be pushed superiorly or partially debulked. This Because of the posterior location of angiofbroma, debulking helps ensure complete tumor clearance.

A sharp chisel is used to cut the bone under the mucosal incisions following the mucosal incision (Fig. The posterior vertical cut needs to enter the maxillary sinus adjacent to the posterior wall of the maxillary sinus and into the large antrostomy5 (Fig. Once the bone forming the medial maxillary wall is mobilized, the nasolacrimal duct will tether the bone an- teriorly and the duct will be visualized (Fig. Note the microdebrider blade that has been placed through the canine fossa trephine. Tumor can now be sinus, further resection of the anteromedial wall and frontal removed from the maxillary sinus under direct visualization. In such If additional access is required and the tumor does not attach cases a canine fossa trephine is not thought to be suitable due to the anterior wall of the maxillary sinus, a canine fossa to the small risk of seeding the tumor into the soft tissues of puncture can be performed. Although seeding is unlikely to occur, this risk is endoscope to be introduced through the anterior wall of the thought to be greater if the entry point into the maxillary sinus maxillary sinus which can be useful to access areas within the is through tumor rather than through normal mucosa. This access is achieved the required angle for dissection in difcult areas such as the by performing a hemitransfxion incision in the opposite nasal anterior wall or anterolateral region of the maxillary sinus. The instrument can then that attaches extensively to the anterior face of the maxillary be passed through the hemitransfxion incision, through the Fig. This allows the passage of a 70-degree dia- fxion incision anteriorly in the left nostril (contralateral side to the mond tipped drill (D).

The mucosa giving greater access to the anterior wall of the maxillary sinus from the posterior wall of the maxillary sinus is elevated (Fig. This exposes the bone and removal of this of approach and usually allows complete access to the entire bone is necessary to expose the pterygopalatine fossa.

In addition the vidian nerve enters the posterior aspect of the fossa before moving laterally to end in the pterygopalatine ganglion which is suspended from the maxillary nerve (Fig. The pterygopala- tine fossa narrows gradually as it opens laterally into the region of the infraorbital fssure and pterygomaxil- lary fssure before widening into the infratemporal fossa (Figs. The roof of the pterygopalatine fossa is formed by the greater wing of the sphenoid bone and the infraorbital fssure, foramen rotundum, and the maxillary nerve coursing from the foramen rotundum from medial to lateral across the roof of the fossa just below the orbital apex (Figs.

Single ventricular (165) arthritis diet inflammation indocin 25mg without prescription, biatrial (145) arthritis medication easy on stomach discount indocin, and simultaneous atrial and ventricular myxomas (151) have been diagnosed accurately by this technique arthritis knee ointment generic indocin 25 mg with mastercard. Similar to rhabdomyomas and fibromas, pericardial effusions have not been reported with atrial myxomas. Surgical results have been excellent (137,138,143,144), with resolution of associated symptoms (137,143,183). Surgery includes wide resection at the point of attachment of the pedicle to the heart. Since attachment most commonly occurs at the fossa ovalis, removal of large segments of the atrial septum is often done. Careful examination of the entire heart is necessary to remove concurrent sites of myxomatous tissue. The use of echocardiography to facilitate a surgical approach has been proposed (184) by preoperatively defining tumor size, location, point of attachment, and the presence of concurrent site involvement. Patients require continual reevaluation for recurrence of disease and for later development of peripheral arterial aneurysms (137,143,146,149,153,167,182). The approximate incidence of recurrence is 4% to 7% in most large series (169,171,185,186). Familial occurrence of cardiac myxomas is well established (137,138,143,144,187,188) and accounts for 7% of all myxomas. Cardiac myxomas often are seen in children and adolescents with multiple lentigines syndromes (164) and may be associated with nonneoplastic endocrine abnormalities (Fig. Recent nosology aggregates these conditions under the broader category of Carney complex, which consists of (a) myxomas in other locations (breast or skin), (b) spotty pigmentation (lentigines, pigmented nevi, or both), and (c) endocrine overactivity (pituitary adenoma, primary pigmented nodular adrenocortical disease, or testicular tumors). The precise gene defects remain unknown (189); however, certain investigators have mapped these syndromes to two loci, on chromosome 2p (190) and chromosome 17q (191). Intrapericardial Teratomas Despite their rare occurrence, intrapericardial teratomas constitute another major subgroup of primary pediatric cardiac tumors (Table 72. These rare tumors previously were associated with a high mortality rate (193,194,195,196,197). More recently, increased survival is emerging as a result of earlier diagnosis and improvements in surgical care (136,193). Intrapericardial tumors are seldom malignant or recurrent; therefore, surgery is considered curative for such life-threatening illness. Intrapericardial teratomas are single, encapsulated, grayish tan, bosselated tumors attached to the base of the heart (197,198,199). Often a broad-based stalk or narrow pedicle firmly attaches the tumor to the root of the aorta or pulmonary artery (193,196,197). The tumor capsule itself can be firmly attached to the aorta (194,195,196,197,198,199,200,201,202,203,204,205,206,207,208) or to pulmonary artery adventitia (195,197,199,205,208). The tumor has been reported to adjoin the superior vena cava (199), right atrium (195,197,199), right ventricle, left atrium, and left ventricle (197). The tumor blood supply usually emanates as nutrient vessels from the aortic vasa vasorum (195,197,205,206). Single blood vessels from the vicinity of the coronary arteries (198) or multiple small blood vessels from the superior mediastinum also may supply the tumor (199). Intrapericardial teratomas may be three to four times the size of the newborn or infant heart (194,197,207); however, the tumor may be relatively small in asymptomatic older children and adolescents. Critically ill newborns and babies almost always have a large pericardial effusion (196,197,205). Obstruction and compression of the heart develop due to an essentially solid tumor mass contained within a restrictive fibrous pericardium (196,197,206). In newborns and infants, the tumor is most frequently right sided, attached to the ascending aorta, and wedged between the aorta and superior vena cava (195,196,203,204,205,206,207,208). These right-sided tumors rotate the heart, on a vertical axis, to the left and posteriorly (197,200,206).
