ABSTRACT
A randomized sample of 100 adults (200 nasal fossae), both sexs, with subjective unilateral or bilateral complaints of nose obstruction and no previous, nose surgeries, was studied. After decongestion, the patency of each nasal was registered according three different evaluations: (a) by the patient himself, (b) by the examiner (inspection, rhinoscopy, endoscopy) and (c) by unilateral anterior active computerized rhinomanometry (Mercury rhinomanometer RN-6) at the reference pressure of 150 Pa. The site and grade of the anatomic abnormalities found in each nasal fossa were also registered. For evaluations (a) and (b), four grades of nasal fossa patency (NFP) were considered: normal (A), slightly abnormal (B), moderately abnormal (C) or severely abnormal (D). Rhinomanometric data (RMD) were distributed in five categories: Group I - RMD of NFP considered normal both by the examiner and the patient; Group II - RMD of NFP considered normal by the examiner but abnormal by the patient; Group III - RMD of NFP considered normal by the patient but abnormal by the examiner; Group IV - RMD of NFP considered slightly abnormal by the examiner and abnormal by the patient; Group V - RMD of NFP considered moderate or severely abnormal by the examiner and abnormal by the patient. The mean inspiratory unilateral resistance in Pa/sec/ccs was 0,33 ñ 0,10 for Group I, 0,39 ñ 0,10 for Group II and 0,52 ñ 0,12 for Group III. The findings of Groups I, II, III and the ones of the Groups IV and V were compared and their clinical implications discussed

The use of a long lasting nasal topic vasoconstrictor (NTVC) 15 minutes before CT-scans of nasal & paranasal cavities (N&PC) would be higbly advisable in order to avoid that normal or pathological transitory engorgement of the nasal mucosa can be interpreted as permanent or semipermanent changes in it, or toavoid that such transitory changes could obliterate the vision or importantanatomic or pathologic details, mostly in the middle meatus - a "K" area for interpretation of anterior sinuses inflamatory diseases. From a group of 10 patients who had CT-scans taken before and after the use of NTVC two cases ilustrates it quite well. The presence of swollen tissues not retracted by NTVC would indicate their permanent or semipermanent change. In evaluating nasal lumen patency, CT-scans after the use of NTVC - coronal or semicoronal sectionstaken for studying N&PC - can provide interesting and realistic correlations with rhinomanometric data from noses also decongested. The purpose of thisshort communication was to reiterate the advantage of NTVC use in N&PC CT-scans

Foi estudada uma amostra aleatória de 110 pacientes masculinos e 92 femininos, adultos, portadores de enfermidades do ouvido, nariz ou garganta, com ou sem obstruçäo nasal. Foram analisadas: a incidência dos diversos tipos de deformidades do septo nasal (DSN) de acordo com a classificaçäo de Mladina (CM); a correlaçäo entre DSN/CM e o sintoma subjetivo de obstruçäo nasal (SSON); a correlaçäo DSN/CM e o sexo dos pacientes; a correlaçäo DSN/CM e fossa nasal predominantemente afetada. As seguintes afirmativas säo estatisticamente significativas - considerando o total da amostra, predominam as DSN/CM tipos 2, 3 e 5: qualquer tipo de DSN/CM pode coexistir com ou sem SSON; o SSON predomina nas DSN/CM tipos 2 e 6; a ausência de SSON predomina largamente nas DSN/CM tipo 1; a DSN/CM tipo 2 predomina claramente na populaçäo masculina; a fossa nasal esquerda é mais afetada pela DSN/CM do que a direita. As DSN/CM tipo 2 envolve a área da válvula, por isso sua relaçäo positiva marcante com SSON é previsível. A correlaçäo entre DSN/CM tipo 2 e trauma explicaria sua predominância na populaçäo masculina. A DSN/CM Tipo 1 - näo perturbando a válvula nasal, por definiçäo - dificilmente será responsável por SSON
