摘要:

AbstractLymphocyte phenotypes were identified by monoclonal antibodies and avidin‐biotin peroxidase reagents and enumerated in tumor tissue removed from 26 patients with head and neck cancer. T lymphocytes (T11) were the predominate phenotype at the tumor margin, with twice as many helper/inducer (T4) as suppressor/cytotoxic (T8) lymphocytes. Patients with Stage II and III carcinoma of the glottis, tongue, and hypopharynx had significantly increased numbers of all T lymphocyte phenotypes when compared to patients with Stage IV disease, thus achieving statistical significance for the T11 and T8 phenotypes. All patients were followed for 2.5 years; those patients who remained free of malignant disease had an increased number of all T lymphocyte phenotypes compared to patients with recurrent malignancy, but this did not achieve statistical significance. Thus, increased numbers of 111 positive lymphocytes of both the T4 and T8 subsets in the tissue at the margins of head and neck tumors were associated with a more favorable prognosis. These results support the concept of an immunologic reaction at the tumor margin, which may be limiting the growth and spread of tumo

摘要:

AbstractIn recent years, diagnostic ultrasound has become established in head and neck surgery. Modern equipment allows high resolution imaging of neck tissue masses, cervical vessels, and lymph nodes. The major advantage of B‐mode sonography is its ability to detect neoplasms in solid scarred neck tissue, commonly seen in patients with radical neck surgery. Postoperative or radiogenic edema, tumor recurrence, and lymph node involvement can be differentiated. Inflammatory and neoplastic lymph node diseases detected by echography must be differentiated by biopsy. Tumor recurrence was seen in 21 of 152 patients by echography. Twelve patients were diagnosed by clinical examination and 17 were diagnosed by computed tomography. Two false positive and one false negative sonographic diagnoses were made. B‐mode sonography is an important instrument in the follow‐up examination of head and neck tumors for early detection of tumor recurrence or tumor persis

摘要:

AbstractUltrasonographic studies of the neck were performed in four patients with metastatic lymph nodes that exhibited limited mobility or fixation to the surrounding tissues on palpation to obtain information about the relationship of nodes to the carotid artery. Comparison of the ultrasonograms with the operative findings disclosed that when a metastatic lymph node adhered to the carotid artery, the lymph node pulsated with flattening of the carotid artery and the echoes between the metastatic lymph node and carotid artery were attenuated.

摘要:

AbstractWe have reviewed the charts of 149 patients who underwent completion thyroidectomies for cancer of the thyroid. The purpose of the study was to evaluate extent of residual disease in the thyroid, and morbidity and mortality of the operation. Residual cancer was found in 58% of the cases, the morbidity was low, and there was no operative mortality.

摘要:

AbstractQuantification of the effect of subcutaneous infiltration of saline with epinephrine and of lidocaine with epinephrine on local cutaneous blood flow was accomplished utilizing the laser Doppler method. A comparison of the onset of vasoconstriction, magnitude of diminished blood flow, and duration of effect was made for several commonly used concentrations of epinephrine. Injected solutions containing epinephrine in concentrations of 1: 200,000 and higher offered good vasoconstrictor effects when both the magnitude and duration of flow reduction were considered. There was a significant (P= 0.0001) difference in flow between epinephrine concentrations of 1:400,000 and all others. There were no significant differences (P>0.05) between concentrations of 1:200,000 and 1:100,000 or 1:100,000 and 1:50,000.

摘要:

AbstractPharyngoesophageal (Zenker's) diverticulum is a relatively common acquired codition that may cause dysphagia and regurgitiation of food. Squamous carcinoma mayi develop in such a dverticulum, but this complication is exceedingly rare and may not be suspected preoperatively. This report describes a case in which the diagnosis of squamous carcinoma was made after regurgitation of malignant tissue from a radiographically proven pharyngoesophageal diverticulum. The patient was treated by simple diverticulectomy and postoperative radiation therapy.

摘要:

AbstractWe present a 76‐year‐old patient with a congenitally mixed capillary/cavernous hemangioma of the tongue, which rapidly enlarged after an unrelated surgical procedure under spinal anesthesia. The enlargement resulted in a significant functional and cosmetic deformity that was corrected by surgical excision. A brief discussion of hemangiomas and their treatment is inclu
