AIM of the study is to identify histological and histochemical peculiarities of nasal septum cartilage reconstruction in patient with different remoteness of trauma. MATERIALS AND METHODS: Patients of both sexes at the age of 16-39 years have been operated on. Depending on remoteness of the period from the trauma, witch caused the deformation, till the surgery, the materials was divided into 2 group: I group (36 patients) 1-5 years from the trauma to the surgery, II group (23 patient) 10-20 years from the trauma to the surgery. Bioptats of the nasal septum cartilage were fixed in Carnoy mixture. Paraffin sections were stained with hematoxilin and eozin, after Van Ghison on collagen fibrils, toluidine blue on acid glycoaminglicans (GAG) and Brashe reaction on RNA. STUDY RESULTS AND CONCLUSION: Thus, the histological and histochemical investigation of nasal septum cartilage, received in rhinoplasty, has revealed dystrophic changes in cartilage. Basing on the analysis of the material, we can conclude that the degree of expression of these changes depends on three factors: - localization of examined area of the nasal septum (bioptat); - the period of time the deformation exist; - the degree of septum curvature. The structure of cartilage bioptates in the patients with relatively short (1-5 years) duration of traumatic deformation differs from the normal hyaline cartilage by moderate dystrophic changes of some chondrocytes (20-25% of all the cells) in the central zone of the cartilage as well as by irregular distribution of acid GAG in cartilage matrix. Cartilage tissue dystrophic changes are still more pronounced in the patients with a longer period of nose deformation including nasal septum curvature. This fact indicates that these changes are connected with deformation duration rather than with etiology of the process. The analysis of material also enable to find the dependence of cartilage dystrophic changes on the degree of nasal septum deformation: at the 3rd degree of curvature, chondropathy is more pronounced than at the 1st-2nd degree.
OBJECTIVE: To investigate the neoplasia of cerebrospinal rhinorrhea (CSR) by making use of mucoperiosteal flap of nasal septum and inferior nasal meatus. METHOD: A retrospective study was reviewed in 9 patients with tumors in nasal cavity and nasal sinuses and in 1 patient with spontaneous cerebrospinal rhinorrhea. Anterior skull base defects were repaired synchronously on the heels of resection of the tumors which damaged anterior basis crania except for 1 patient with spontaneous cerebrospinal rhinorrhea which was restored directly. RESULT: Among the 10 patients there were 5 patients with the destruction on ethmoidal horizontal plate, 2 patients with the destruction on hanging wall of ethmoid, 2 patients with the destruction on hanging wall of fossa orbitalis, 1 patient with the destruction on ethmoidal horizontal plate and on hanging wall of sphenoidal sinus simultaneously and all the destructions were repaired following detection of it synchronously. CONCLUSION: During the operation of tumors in nasal cavity and/or nasal sinuses when anterior skull base defect is found and the CSR occurs we can take advantage of mucoperiosteal flap of nasal septum and inferior nasal meatus to perform the transplantation of mucoperiosteal flap in order to avoid forming cerebrospinal rhinorrhea.
The nasal septum plays a paramount role in determining nasal aesthetics and nasal function. Surgical management of the nasal septum often presents a challenge to even the most skilled nasal surgeon. A firm understanding of anatomic and physiologic aspects of the nasal septum will allow the rhinoplasty surgeon to better deal with this component of nasal reconstruction.

The aim of this work was: 1) differentiation and systematization of the bone elements originated on the base of the nasal septum cartilage, 2) systematization of the cribriform plate, 3) investigation and systematization of the bottom elements of the sphenoid recess in young pairhoofed mammals. The material and methodology was described elsewhere (part I and IV-A). The additional material were 6 skulls of wild boar. The nasal septum diploe constituted of two biomechanical systems: anterior and posterior. The first one is situated in the sphenoid septum and corps. the second in diploe laminae perpendicularis of the alar bone. The cribriform plates and parasphenoid stabilize the osseous nasal septum system in the splanchnocranial space--without signs of the biomechanic binds between diploetic elements. The floor sphenoid recess for two plates: the lamina transversalis posterior and laminae transversalis parasphenoidei. The results of these investigations was the verification of the absence of "mesoethmoid in mammals as well in birds, fishes and amphibians. The traditional system of the ethmoid bone organization in this way turned out to be illusory.
The nasal septum is a particularly rare site of origin of chondrosarcoma. Cranial base invasion may be at hand, with such lesions making complete tumor removal difficult. MRI techniques allow precise definition of tumor extent. In the described case, CT and Dynamic MR imaging were performed in a case of chondrosarcoma of the nasal septum. Imaging clearly illustrated size and extent of the mass with central regions of internal calcification. Dynamic MRI was additionally performed, which helped to define the presumed origin of the lesion from the nasal septum.
For nasal fracture presenting saddle nose deformity, the nasal septum was fixed with the frontal process of the maxillary bone by Kirschner wire. Good results were confirmed with computed tomography, and there was no secondary deformity. This method is easy and provided a firm support for nasal septum. By burying Kirschner wire under the skin, it can be left intact for sufficient time, without disruption of daily life.
The nasal resistance of 28 patients with nasal septum deviation was measured before and after septum correction according to Cottle by means of body plethysmography. Clinical state according to clinical state history and body plethysmography results before and after surgery are compared by means of a standardised measuring unit. There was statistical significance for improvement of nasal ventilation after surgery in all three parameters. An analysis of the discrepancy between history, clinical state and rhinomanometry was made. History and rhinomanometry correlated closely. They seemed to be the most important parameters to determine nasal complaints. 30 volunteers with normal breathing function of the nose were examined. The normal resistance values of both nasal cavities are 0.31 kPa/l/sec. before and 0.28 kPa/l/sec after shrinkage of the nasal mucosa. The normal values of the nasal airflow of the entire nose were compared with the measurements of the patient group.
The nasal resistance of 17 patients with nasal septum deviation was measured before and after septum correction using two active rhinomanometric methods; the one with external flow (oscillation method), the other with spontaneous flow. Both methods correlated closely (p less than 0.01). The oscillation method proved to be as reliable and sensitive as the spontaneous flow method and less strenuous for the patient. Conventional rhinomanometric methods have failed especially in children because of their great demands on the patient's compliance; thus the oscillation method serves to increase the clinical application of rhinomanometry.
The aim of this investigation was the study of the development changes of the osseous nasal septum and para-sphenoid systems in adult pigs, domestic cattle and the comparison with the control skull-group of 10 deer and 15 hares. The methodology was described elsewhere. In paired-hoof mammals was found that the alar bone is biomechanically composed system. It represents four segments: three of septum bone and one as subnasal bone. In examined mammals the degree of integration of sphenoid septum and alar bone ones was various. In fishes, amphibians, birds and paired-hoof mammals there are the axially palate system too. The para-sphenoid mechanically integrated itself with the hard palate.

We used scanning electron microscopy to study and compare the histologic and ultrastructural aspects of the mucosa of the anterior portion of the septum (APS) and the anterior portion of the inferior concha (APINC) in 10 healthy adults and 10 cadavers. We found that (1) in most cases, the types of epithelium were generally the same in both areas--pseudostratified cylindrical ciliated epithelium with goblet cells (respiratory epithelium), stratified cuboidal epithelium, and stratified squamous nonkeratinized epithelium; (2) the APINC had more respiratory epithelium than the APS; (3) the APS had more squamous epithelium than the APINC; (4) the basement membrane of the APINC was thicker than that of the APS; (5) moderate chronic inflammatory infiltrate was more common in the APINC, and mild infiltrate was more common in the APS; and (6) the APINC had more mucous glands and the APS had more serous glands.
The deviated nasal septum may be associated with middle ear problems, particularly on the side of nasal obstruction. This study aims to find out whether middle ear pressure (MEP) correlates with the degree of nasal obstruction secondary to a deviated nasal septum, and to examine changes in MEP following septal surgery. Patencies of the nasal passages (measured with a peak nasal inspiratory flowmeter) and MEP (measured with a tympanometer) of 55 patients were obtained prior to surgery and 7.5 (6-10) months post-operatively [median (range)]. Forty patients completed the study. Results were analysed by linear regression. In the ear on the side of nasal blockage, MEP was -25.7 +/- 28.4 mm water pre-operatively, and following surgery increased significantly to -2.9 +/- 30.4 mm water (mean +/- SD) (P < 0.001). Pre-operatively, it was inversely related to the difference in patencies between the two nasal passages (r = -0.32, P < 0.02). Post-operatively, its improvement correlated with the degree of reduction of asymmetry of airway patency (r = 0.56, P < 0.001).
A deviated nasal septum not only can cause a blocked nose, but may also be associated with headaches. This study evaluates the nature of these headaches, the effect of submucous resection of the nasal septum, and the factors associated with postoperative headache relief. Deviated nasal septa were corrected by submucous resection in 99 men and 17 women. Patients were studied at 4 to 48 months (mean 18 months) postoperatively. Fifty-five of the 116 patients studied (47.4%) had preoperative recurring headaches. Thirty-five of the 55 patients with headaches (63.6%) experienced relief (complete or partial) of their headaches at a mean follow-up period of 18 months. Patients were more likely to be relieved of their headaches following submucous resection if the headaches were most intense over the frontal region, pressurelike in nature, and if the submucous resection resulted in relief of nasal obstruction. It is possible that headaches recur in the long term, and it is postulated that central mechanisms play a role.

The present study examines the relative contributions of the nasal septum and airway volumes to the total volume of the fetal nasal capsule. For comparative purposes, 29 human fetal specimens (20 "normal" and 9 with cleft lip and palate (CLP] were celloidin embedded, sectioned, and stained with hemotoxylin and eosin. The specimens ranged from 8 to 21 weeks in postmenstrual age. Photomicrographs of the serial sections allowed selected anatomic structures to be computer digitized, reconstructed as three-dimensional computer representations, and quantified. Various nasal capsule component measurements were compared with overall nasal capsule size values, producing relative size indices. Significant differences (p less than 0.05) were noted between the "normal" and CLP fetal samples in the relative sizes of the nasal capsule, airways, and septum. Relative mean CLP nasal capsule volume was 14% smaller than normal, relative mean CLP airway volume was approximately 43% smaller than that of the normal specimens, whereas relative mean CLP septum volume was approximately 45% larger. Aspect ratios (i.e., height:width ratios) were utilized for shape analysis of the nasal septal cartilage and indicated that the CLP septal shape was one of increased width relative to height compared with normal specimens. Results were consonant with clinical impressions of nasal capsule deficiency in the CLP nasal capsule and revealed some new structural associations in the fetal nasal capsule.
