  • 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.

  • intraNasal localization of the lacrimal sac
    Archives of Otolaryngology-head & Neck Surgery, 2009
    Co-Authors: Mustafa Orhan, Canan Saylam, Rasit Midilli
    Abstract:

    Objective To optimize the approach to the lacrimal sac during intraNasal dacryocystorhinostomy. Design Microscopic measurement of anatomical landmarks in cadaver sagittal head sections. Setting The anatomy department of a large university hospital. Participants Twenty adult cadaver sagittal head sections (12 right and 8 left) fixed with 10% formaldehyde solution were evaluated. Intervention During endoscopic dissections, the maxillary line, lacrimomaxillary suture, nasolacrimal duct, and lacrimal sac were exposed. Main Outcome Measures Greater knowledge of the relationship among anatomical structures. Results The entire lacrimal sac was in 2 of 20 sides anterior and in 3 of 20 sides posterior to the axilla of the Middle Nasal Concha. The fornix of the lacrimal sac was situated above the axilla in all sides. We evaluated the localization of the lacrimal sac to the maxillary line, which is of clinical importance in intraNasal osteotomy during dacryocystorhinostomy. In 17 of 20 sides it is possible to reveal the axilla of the Middle Nasal Concha during osteotomy. Conclusions Underexposure or lack of true localization of the sac are the most frequently encountered reasons for dacryocystorhinostomy failure. The maxillary line and adhesion point of the Middle Nasal Concha are the 2 most important landmarks in localization of the sac. A mucosal incision anterior to the maxillary line and dissection up to the point where the Middle Concha adheres, followed by osteotomy on the lacrimomaxillary suture, nearly always ensure the exposure of the sac.
