摘要:

AbstractSix patients with malignant head and neck tumors are shown to have required electron microscopy for accurate diagnosis. In all of these tumors, there were ultrastructural features of cytodifferentiation that were not discernible by light microscopy, such as neurosecretory granules, desmosomes, cytoplasmic processes, tonofibrils, and myofilaments. Electron microscopy is helpful in the differential diagnosis of tumors in general, but its effectiveness is particularly apparent in small‐cell “undifferentiated” tumors such as neuroblastoma, rhabdomyosarcoma, Ewing's sarcoma, undifferentiated squamous‐cell carcinoma of the lymphoepithelioma type, and malignant lymphoma. It has also been helpful in the identification of amelanotic melanoma and spindle‐cell

摘要:

AbstractThere has been considerable controversy over the years regarding the distinctions between various disorders characterized by a necrotizing and granulomatous inflammation of the tissues of the upper respiratory tract and oral cavity. It now seems clear that if infections and other known agents can be excluded, three clinicopathologic entities remain: Wegener's granulomatosis (a systemic disease), idiopathic midline (nonhealing) granuloma, and premalignant or malignant lymphoreticular lesions. The antigenic stimulus for all three may be related but remains unidentified.

摘要:

AbstractThe author presents his personal method of repairing a bilateral cleft lip, focusing on both the embryogenic factors of this condition and its anatomicfunctional abnormalities. The surgical technique used enables correction in a single operation through suture of the lateral portions at the midline and elevation of the bifurcated flap of the prolabium to form the columella and the nasal floor. The deep psychological, social, and economic impact of the pathology is discussed, and the importance of a one‐step surgical correction of the defect for the particular patient population at question is stresse

摘要:

AbstractOur high‐speed and increasingly aggressive society, coupled with a continuing rise in necessary surgery of the neck and adjacent areas, accounts for the current increase in patients afflicted with vocal‐cord paralysis. Such patients may sustain relatively little persistent loss of function (e.g., when only one cord is involved, which then regains function or becomes compensated) or considerable loss (as in cases of bilateral vocal‐cord paralysis). To improve on existing methods of dealing with these problems, the author has developed and refined the nerve‐muscle‐pedicle technique for reinnervating paralyzed muscles. A nerve‐muscle pedicle obtained from the ansa hypoglossi branch to the omohyoid muscle or another strap muscle can be used to selectively reinnervate the posterior cricoarytenoid muscle in cases of bilateral‐cord paralysis, or for selective reinnervation of the lateral thyroarytenoid muscle in cases of unilateral‐cord paralysis. The bilateral reinnervation technique showed a 90% success rate in 90 patients, as demonstrated by their ability to sustain reasonable day‐to‐day activity without needing a tracheotomy tube and without manifesting further loss of voice. The unilateral technique has yielded promising results in a limited number of carefull

摘要:

AbstractThe classification, embryology, histopathology, clinical features, and treatment of benign jaw cysts are presented. Emphasis is placed on the differentiation of benign cysts from malignant radiolucent lesions of the jaws. Preservation of adjacent teeth and other vital structures is of paramount importance in the management of jaw cysts.

摘要:

AbstractThe termadenomais applied to a rather wide variety of histopathologic entities in the salivary glands. These include tumors derived from the ductal epithelium and/or from myoepithelial cells and other salivarygland elements, such as the sebaceous glands. Within the categories of mixed tumor (pleomorphic adenoma), monomorphic adenoma, clear‐cell tumor, and sebaceous lesions, there are also several subtypes, each of which lends further credence to the germinative potential of the salivary tissues. Presented in this report is a clinicopathologic and histogenetic analysis of these lesions. Specifically discussed are mixed tumor, monomorphic adenoma, carcinoma ex‐pleomorphic adenoma, clear‐cell tumor, sebaceous lymphadenoma, and sebaceous carc

摘要:

AbstractA rare case of angiosarcoma of the maxillary sinus is reported. Review of the literature concerning angiosarcoma of the head and neck revealed 14 previously published cases involving the nose, nasal sinuses, and nasopharynx. Angiosarcoma of the skin and soft tissues of the head and neck differs in behavior from that affecting the nose, nasal sinuses, and nasopharynx. The case reported presents the protracted clinical course of this malignant tumor.
