  • preoperative computed tomographic evaluation of inferior Nasal Concha hypertrophy and its role in deciding surgical treatment modality in patients with deviated Nasal septum
    International Journal of Morphology, 2009
    Co-Authors: Sumit Mrig, A K Agarwal, J C Passey
    Abstract:

    Un tabique Nasal desviado esta asociado con una hipertrofia compensatoria de la Concha Nasal inferior del lado contra lateral. En el pasado se realizaba septoplastia convencional para el tabique desviado, lo que mejoraraba la permeabilidad en el lado de la desviacion, pero agravaba esta en el lado opuesto, debido a la reacomodacion del tabique en el plano mediano. En el presente estudio se evaluo en 50 pacientes la composicion anatomica de las Conchas Nasales inferiores, basado en la exploracion a traves de tomografia computarizada, y de esta manera ayudar al otorrinolaringologo a determinar si es necesario o no, anadir la plastia de la Concha Nasal inferior al procedimiento de septoplastia estandar.

    Abstract:

    SUMMARY : Deviated Nasal septum is associated with compensatory hypertrophy of the inferior Nasal Concha on the contralateralside. In the past conventional septoplasty was done for the deviated septum, which would improve the patency on the side of dev iation butwould worsen it on the opposite side due to reallocation of the septum to the midline. The present study of 50 patients unfolds theanatomical composition of the inferior Nasal Concha based on the computed tomographic scan and help the otolaryngologist to det erminewhether to add turbinoplasty to standard septoplasty procedure or not. KEY WORDS: Deviated Nasal septum; Inferior Nasal Concha; Contralateral hypertrophy. INTRODUCTION In patients with Nasal obstruction and anterior septaldeviation to one side, a common finding is a varying degree ofconcomitant or compensatory inferior Nasal Concha hypertrophyin the side of the nose opposite the major septal deviation. Adetailed description of the Nasal Conchas bones was first givenby Casserius (1609) who recognized that three are usually presentand consist of true bone, not cartilage (Pratt, 1915; Dixon, 1949)have described the common association of deviated Nasal septumand contralateral inferior Nasal Concha enlargement.The Nasal Conchas exists as three and sometimes fourbilateral extensions form the lateral wall of the Nasal cavity.At inspiration up to two-thirds of upper airway resistance isproduced by the anterior tip of the inferior Nasal Concha in theregion of the internal Nasal valve. In a recent study on theNasal valve Haight & Cole (1983) confirmed that “the greaterportion of the Nasal resistance is situated at the level of theanterior end of the inferior Nasal Concha”.Of the three Nasal Conchas the inferior Nasal Concha isthe most susceptible to enlargement. It is seen that the inferiorNasal Concha hypertrophy is usually observed in septaldeviation (Compensatory hypertrophy) and in allergic or va-somotor rhinitis (Lai & Corey, 1983; Li

  • anatomical variations in the human paraNasal sinus region studied by ct
    Journal of Anatomy, 2000
    Co-Authors: I Perezpinas, J Sabate, A Carmona, C J Catalinaherrera, J Jimenezcastellanos
    Abstract:

    A precise knowledge of the anatomy of the paraNasal sinuses is essential for the clinician. Conventional radiology does not permit a detailed study of the Nasal cavity and paraNasal sinuses, and has now largely been replaced by computerised tomographic (CT) imaging. This gives an applied anatomical view of the region and the anatomical variants that are very often found. The detection of these variants to prevent potential hazards is essential for the use of current of endoscopic surgery on the sinuses. In the present work, we have studied the anatomical variants observed in the Nasal fossae and paraNasal sinuses in 110 Spanish subjects, using CT in the coronal plane, complemented by horizontal views. We have concentrated on the variants of the Nasal septum, middle Nasal Concha, ethmoid unciform process and ethmoid bulla, together with others of lesser frequency. The population studied showed great anatomical variability, and a high percentage (67%) presented one or more anatomical variants. Discounting agger nasi air cells and asymmetry of both cavities of the sphenoidal sinus, which were present in all our cases, the variations most often observed were, in order, deviation of the Nasal septum, the presence of a Concha bullosa, bony spurs of the Nasal septum and Onodi air cells.

  • enchondroma of the Nasal septum due to ollier disease a case report and review of the literature
    Head and Neck-journal for The Sciences and Specialties of The Head and Neck, 2015
    Co-Authors: Christian Manuel Claus Jacobi, Egodage Samitha Hiranya, David Holzmann, S Kollias, Michael B Soyka
    Abstract:

    Background Morbus Ollier is characterized by the presence of multiple enchondromas (ie, benign intraosseous cartilaginous lesions). Although their manifestation in the limb bones is well described, only a few cases with ear, nose, and throat (ENT) involvement, primarily arising from the skull, have been reported. The malignant transformation toward slowly growing low-grade chondrosarcomas is the most severe form of progression. Methods We report a unique case of a 54-year-old patient with Ollier disease with an extensive Nasal enchondroma apparently eroding the middle Nasal Concha and expanding to the lateral Nasal wall that raised suspicion of malignant transformation. Results Radiological and histological features of enchondromas can be controversial and seem to have limited sensitivity to exclude low-grade malignancy. The clinical symptoms play a decisive role in differentiation between enchondromas and low-grade chondrosarcomas. Conclusion Surgery remains the only effective solution in removing an enchondroma and preventing the tendency toward malignant transformation. © 2014 Wiley Periodicals, Inc.
