Carcinoid Tumor of the Middle Ear
(W B Saunders Co-elsevier inc, 2008) Sahan, Murat; Yildirim, Nadir; Arslanoglu, Atilla; Karslioglu, Yidirim; Kazikdass, Kadir Cagdas
Carcinoid tumor of the middle ear is an extremely rare lesion of the middle ear, and thus its diagnosis is frequently delayed. Some authors found it hard to differentiate middle ear carcinoid front the middle car adenoma. However, the balance of opinion is currently oil the side of considering it as a separate clinical entity. Definitive diagnosis is made by identifying neurosecretory tumor cells using immunohistochemistry and electron microscopy. It usually follows a nonaggressive clinical course, rarely metastases, and infrequently recurs after radical excisions. We present a patient with middle ear carcinoid, who is free of disease 2 years after the resection of the tumor mass with canal walldown procedure. The relevant literature is also herewith reviewed.

Imaging Findings of Bisphosphonate-Related Osteonecrosis of the Jaw With Emphasis on Early Magnetic Resonance Imaging Findings
(Lippincott Williams & Wilkins, 2009) Krishnan, Anant; Arslanoglu, Atilla; Yildirm, Nadir; Silbergleit, Richard; Aygun, Nafi
Purpose: To describe the imaging findings of bispbosphonate-related osteonecrosis of the jaw (BRONJ) with emphasis on early magnetic resonance imaging (MRI) findings. Materials and Methods: The medical records and computed tomography. MRI, and bone scintigraphy images of 5 female and 1 male patients (n = 6) between the ages of 49 and 79 years (mean age, 70 years) who had a diagnosis of BRONJ were retrospectively reviewed, and temporal changes in imaging features were noted. Results: The earliest MRI finding was tire loss of the normal TI hyperintensity of fatty marrow in the mandible and maxilla. The MRI findings of more advanced BRONJ included bone destruction, Soft tissue edema and enhancement. interior alveolar nerve thickening. and pterygoid muscle swelling and enhancement. On computed tomography, sclerosis and subtle lucencies (widening) of the periodontal ligament and cortex and around the apices of the teeth in the early stage, and osteolytic bone lesions, cortical disruption, and frank bone fragmentation in the later stages were observed. Bone scintigraphy showed increased uptake early in the disease. Conclusions: Osteonecrosis of the mandible and maxilla occurs as a complication of bisphosphonate treatment of bone metastasis and ostcoporosis and typically manifest after a dental procedure. Magnetic resonance imaging, and bone scintigraphy findings may precede clinical symptoms and mimic metastatic disease.
Interlaminar Discectomy in Lumbar Disc Herniation: Shorten Postoperative Return To Work Period in Recruits Undergoing Military Training
(Oxford Univ Press, 2008) Celik, Haydar; Derincek, Alihan; Arslanoglu, Atilla
The operative treatment of lumbar disc disease has long challenged spine surgeons. In this study, we aimed to show that recruits with lumbar disc herniation managed by the interlaminar approach could return to work after 6 weeks. Forty male recruits were included in this study and interlaminar discectomy was adequate in 40 cases. Early postoperative rehabilitation had a positive effect on early return to work. We believe that interlaminar lumbar discectomy is an effective technique for treating patients with herniated lumbar discs; with early postoperative rehabilitation, recruits can return to work 6 weeks after surgery.
Klippel-Feil Syndrome and Associated Ear Anomalies
(W B Saunders Co-elsevier inc, 2008) Yidirim, Nadir; Arslanoglu, Atilla; Mahirogullari, Mahir; Sahan, Murat; Ozkan, Huseyin
Background and purpose: Klippel-Feil syndrome (KFS) is a congenital segmentation anomaly of the cervical vertebrae that manifests as short neck, low hair line, and limited neck mobility. Various systemic malformations may also accompany the syndrome including wide variety of otopathologies affecting all 3 compartments of the ear (external, middle, and inner ear) as well as internal acoustic canal and vestibular aqueduct. We aimed to investigate these involvements and their clinical correlates in a group of patients with KFS. Materials, methods, and results: We present 20 KFS cases, of which 12 (% 60) displayed most of the reported ear abnormalities such as microtia, external ear canal stenosis, chronic ear inflammations and their sequels, anomalies of the tympanic cavity and ossicles, inner car dysplasies, deformed internal acoustic canal, and wide vestibular aqueduct, which are demonstrated using the methods of otoscopy, audiologic testing, and temporal bone computed tomography. Conclusions: This series represents one of the highest reported rate of ear involvement in KFS. We found no correlation between the identified ear pathologies and the skeletal and extraskeletal malformations. The genetic nature of the syndrome was supported by the existence of affected family members in 4 (20%) of the cases. (C) 2008 Elsevier Inc. All rights reserved.
Otologic and Leptomeningeal Involvements as Presenting Features in Seronegative Wegener Granulomatosis
(W B Saunders Co-elsevier inc, 2008) Yidirim, Nadir; Arslanoglu, Atilla; Aygun, Nafi
Wegener granulomatosis is an immune-mediated, systemic vasculitis with unknown etiology that can be seen in almost any anatomical site. Positivity for antineutrophil cytoplasmic antigene, which is a serological marker, and presence of granulomatous vasculitis in histopathologic specimens from the lesions are accepted as diagnostic. A case of Wegener granulomatosis whose presenting symptoms and signs are related to otologic and meningeal involvement of the disease is reported. Apart from atypical presentation, histopathological and serological findings from this patient remained negative throughout the course of the disease, and the diagnosis was made on the basis of clinical and secondary laboratory findings. We herewith discuss this unusual case in the light of relevant literature. (c) 2008 Published by Elsevier Inc.
Rhinolithiasis: Clinical, Radiological, and Mineralogical Features
(Ocean Side Publications inc, 2008) Yidirim, Nadir; Arslanoglu, Atilla; Sahan, Murat; Yidirim, Altan
Background: Rhinolithiasis is a rare and under-diagnosed clinical entity whose etiology and pathogenesis is poorly understood. Objective: The objective of the study is to review the clinical and radiologic features of rhinolithiasis and mineralogical-chemical composition of the rhinoliths with the aim of shedding light on its etiology and pathogenesis. Methods: Our subjects consisted of 8 rhinolithiasis cases. Clinical presentations, signs, and symptoms of the patients with radiologic findings are presented, and X-ray diffraction analyses of the stones were carried out to assess their mineralogical composition. Results: Nasal obstruction appeared to be the chief symptom, followed by nasal discharge and facial pain. Neither exogenous nor endogenous nidi were identified in any of the cases. Mineralogical analyses of the rhinoliths revealed Whitlockite [(Ca,Mg)3 (PO4)2] in one and Dahllite [Ca5 (PO4,CO3)3OH] in 7 cases. Conclusion: We hypothesized that some substances or organic objects form the nidi of the rhinoliths and are disintegrated over the course of mineral precipitation. This hypothesis was supported by radiologic and microscopic findings.
