Computerized tomography or paranasal sinus neoplasms.

Computerized tomography represents a new and valuable diagnostic tool to the otolaryngologist and head and neck surgeon in several ever-increasing aspects of his clinical practice. This report presents CT scans utilizing the E.M.I 5005 body scanner on patients with neoplasms of the paranasal sinuses presenting to the Head and Neck Service of The University of Texas System Center M. D. Anderson Hospital and Tumor Institute. Only patients undergoing surgical resection of such lesions are included so that actual operative and surgical pathological findings can be used for critical comparison of diagnostic information derived from polytomography and computerized tomography. Seven illustrative cases are presented. In general, computerized tomography has been found to be equal to polytomography in assessing bone destruction or involvement by tumor, and superior to polytomography in determining accurately the soft tissue extent of disease. CT scanning, however, has been found to have limitations in the delineation of soft tissue disease in areas of high contrast in tissue density, and in the evaluation of possible intracranial tumor extension in isodense, avascular lesions.

Management of paranasal sinus neoplasms invading the orbit.

Sinus tumors can readily invade the orbit through their shared walls. The initial symptoms of a sinus neoplasm are often due to orbital invasion. A comprehensive overview of the pathology, diagnosis, and treatment of these tumors is presented.

[Rescue operations of the recurrent nasal and paranasal sinus neoplasms].

OBJECTIVE: To investigate the symptoms, factors relating to recurrences, the styles of the rescue operation and the reconstructive methods of the surgical defects in patients with recurrent nasal and paranasal sinus neoplasms. METHODS: Excluding the primary neoplasm, only patients with recurrent tumors and suitable for rescue operations entered the group. Kaplan-Meier method was used to estimate the survival probability. RESULTS: Twenty-five patients receiving rescue operations from 1993 to 2002 who met the above inclusion criteria were reviewed. The age ranged from 13 - 66 years. All the patients had once surgery or radiation therapy at least. The time between the last treatments and the recurrences ranged from 2 weeks to 46 months. 80 per cent of the recurrences were within the first 2 years after the last therapy. The recurrent symptoms included headache (10 patients), eminences in or around the operation fields (9 patients), diminution of vision (7 patients), and so on. The patients were followed 1 to 65 months. There were no patients died during the rescue operations. Five patients were alive without recurrences and 3 alive with local or regional recurrences. Thirteen died of local recurrences and 1 died of metastasis to lung. The one-year, 2-year and 3-year survival rate were 62.5%, 43.7% and 29.1%, respectively. The median survival time was 18 months. Complications included cerebrospinal rhinorrhea (3 patients), central diabetes insipidus (1 patient) and necrosis of part of the flap (1 patient). CONCLUSIONS: Most of the local recurrences occur within 2 years after the last therapies. The recurrent symptoms are commonly headache and eminences in or around the operation fields. The recurrences are closely related to pathological types and differential degrees of the neoplasms. The reasonable and timely combined treatment may help to decrease the frequencies of the recurrences. The rescue operations with effective methods can improved the patients' life qualities and lengthen their life spans. The main complications are cerebrospinal rhinorrhea most of which can be cured by conservative treatment.

[Place of radiotherapy in therapy of nose and paranasal sinus neoplasms. Results in 63 patients].

Therapeutic results in patients with cancer of the nasal cavity and paranasal sinuses of the own clinic are analysed together with some results published in literature. In early cases with cancer of the nasal cavity and cancer of the infrastructure of the maxillary antrum, the results of radiotherapeutic or surgical treatment are equal. In all the other cases -- the majority of the patients -- combined treatment with surgery and high-dose radiotherapy is superior to either treatment modality alone. The 5-year cure rates are: in early cases about 60% and in the other cases about 30%. The distribution of stages in our patients from 1963 to 1973 shows that the majoirty is in a more or less advanced stage of the disease at the time of diagnosis, comparable to earlier reports.
