Incidence of childhood cancer of the head and neck in Germany.
2007
Background: Only very limited data are available in the literature on the incidence of childhood cancer of the head and neck worldwide. Methods: Based on data obtained from the national German Childhood Cancer Registry, a total of 370 malignancies of the head and neck in children under the age of 15 (199 boys and 171 girls), which were reported to this institution between 1994 and 2003, were analysed in this study. Results: The overall incidence of malignancies of specific sites of the head and neck in Germany is 4.48 per 100000 children. The most frequently observed entities, representing primary tumours, are soft tissue sarcomas (0.39/100000), lymphomas (0.09/100000) and thyroid carcinoma…
Mandibular osteoma as a cause of ankylosis and progressive trismus.
2021
Osteomas are benign tumours of bone tissue restricted to the craniofacial skeleton. The aim of this article is to present and discuss the demographic and clinical aspects and the management of craniomaxillofacial osteomas. When the patient was submitted from primary care to our hospital, he was 68 years old, and he had ankylosis of the temporomandibular joint for the previos 4 years. A CT scan was performed, finding a giant mandibular osteoma. Conservative treatment and radiological follow-up were carried out with clinical stability. Osteomas more often are seen in the paranasal sinuses and in young adults, with no differences in gender. Most are asymptomatic, but they can cause local probl…

Accidental displacement and migration of endosseous implants into adjacent craniofacial structures: A review and update
2011
Objectives: Accidental displacement of endosseous implants into the maxillary sinus is an unusual but potential complication in implantology procedures due to the special features of the posterior aspect of the maxillary bone; there is also a possibility of migration throughout the upper paranasal sinuses and adjacent structures. The aim of this paper is to review the published literature about accidental displacement and migration of dental implants into the maxillary sinus and other adjacent structures. Study Design: A review has been done based on a search in the main on-line medical databases looking for papers about migration of dental implants published in major oral surgery, periodon…
Dynamische Bildgebung der Nasenhaupthöhle und der Nasennebenhöhlen im MR mittels polarisiertem 3Helium
2001
sinuses with polarized 3 helium MRI. Purpose: Reduced or blocked ventilation of the paranasal sinuses is probably the most important factor in the development of sinusitis. Recently, the use of optically polarized noble gas isotopes has attracted increasing interest for use in a variety of promising MR applications. The aim of this study was to test the feasibility of imaging and visualization ventilation of the nasal cavity and paranasal sinus in MR by inhalation of hyperpolarized 3 helium. The goal was to evaluate ventilation defects of the paranasal sinuses. Volunteers and Methods: Three volunteers were enrolled in the study. 3 Helium was polarized to 40-50% by direct optical pumping. 30…
Malignant and benign sinonasal paragangliomas
2013
Objectives/Hypothesis To report on the clinical course and management of sinonasal paragangliomas (PGLs). Study Design and Methods Retrospective chart review of six patients with PGLs of the nasal cavity and paranasal sinuses. Results Three patients had tumors with malignant clinical behavior with cerebral metastases or infiltration of brain and local recurrence, despite surgery and/or radiotherapy, while three patients demonstrated a benign course. Conclusion Sinonasal paragangliomas are frequently malignant. If malignant, they are very aggressive, with rapid local spread as well as high metastatic potential despite surgical resection; and they have a poor prognosis. Malignancy cannot be d…
Yamik Sinus Catheter in the Topical Treatment of Patients with Acute Rhinosinusitis after Previous Sinus Surgery
2002
Background The Yamik sinus catheter was designed as a new device for the topical treatment of rhinosinusitis. It creates intermittent positive and negative intranasal pressure after sealing the ipsilateral nostril and choana with two inflatable cuffs. Affecting the nasal cavity and all paranasal sinuses of one side at a time, it is used to evacuate mucous and secretions as well as and to introduce antiseptic, antibacterial, or antifungal solutions. Methods This study was designed to evaluate the effectiveness of the Yamik catheter in cases of acute purulent rhinosinusitis in patients who previously underwent endonasal sinus surgery for chronic rhinosinusitis. Twenty patients were treated at…
Sinonasal respiratory epithelial adenomatoid hamartoma: A report on three cases
2018
Respiratory Epithelial Adenomatoid Hamartoma (REAH) is a rare benign lesion that may occur in the nasal cavity and paranasal sinuses. Histology is essential for the differential diagnosis with other lesions that could affect the sinonasal region. Our report focuses on three cases of male patients that were 46, 66 and 73 years old, diagnosed with REAH of the sinonasal region. All cases presented a nasal obstruction and hyposmia, and in one case cephalalgia. The definitive diagnosis of REAH was supported by the endoscopic, radiological and histological examinations. The patients underwent surgical excision with an endoscopic approach and did not experience a local recurrence at the time of wr…
Respiratory epithelial adenomatoid hamartoma: An unusual case report
2020
Respiratory epithelial adenomatoid hamartoma is a rare lesion of the nasal cavity whose etiology and pathogenesis are unknown and symptoms are unspecific. It can be isolated or associated with inflammatory process, first of all nasal polyposis. It’s considered a rare lesion because it’s poorly known and consequently correctly diagnosing is important to a right surgical treatment and follow-up. A 54-year-old man presented with a 10-year history of epistaxis, rhinorrhea and anosmia. Computed tomography showed soft tissue densities in all sinus cavities consistent with nasal polyposis and without bilateral widening of the olfactory cleft >10 mm and without bone erosion. Functional endoscopi…
Myospherulose des Mittelohres - eine seltene Differenzialdiagnose des Cholesteatoms
2004
Background Myospherulosis is a chronic-inflammatory lesion that is most commonly iatrogenic of origin and occurs in tissues exposed to petrolatum-based products. The disease does not exhibit characteristic symptoms and is therefore not diagnosed in some instances. In previous otorhinolaryngological studies, myospherulosis was mainly found in paranasal sinuses, while only four otitic cases have been reported. Methods A 48-year-old female Egyptian patient suffered from bilateral chronic otitis media that had been treated in Egypt by tympanoplasty. The patient presented few months later at the university ENT department (Mainz) with deteriorated otorrhea and otalgia. Clinical, otoscopical, and …
