salivary duct carcinoma with perineural spread to Facial Canal f 18 fdg pet ct detection
Clinical Nuclear Medicine, 2008Co-Authors: Ba D. Nguyen, Michael C. RoarkeAbstract:Salivary duct carcinoma is a highly aggressive malignancy targeting predominantly the parotid gland. It frequently involves the extracranial portion of the Facial nerve and has a propensity to metastasize through the temporal bone via perineural spread. The authors present a case of treated parotid malignancy with F-18 FDG PET/CT detecting abnormal radiotracer uptake within the Facial Canal from perineural tumor recurrence. The positive PET/CT finding was confirmed by subsequent MR examination. Postradiation PET/CT surveillance showed resolution of the perineural metastasis with unfortunate distant ischial bone dissemination.

prevalence of Facial Canal dehiscence and of persistent stapedial artery in the human middle ear a report of 1000 temporal bones
Laryngoscope, 1994Co-Authors: Michael M Paparella, Edwin H Moreano, Daniel Zelterman, Marcos V GoycooleaAbstract:A total of 1000 temporal bones were used to study the prevalence of Facial Canal dehiscence and of persistent stapedial artery in detail. Of the temporal bones studied, 560 (56%) contained at least one Facial Canal dehiscence. There was a 76.3% prevalence of bilaterality of this Canal wall gap. The most common site of dehiscence was the oval window area. The concept of microdehiscence of the Facial Canal is introduced. One third of the temporal bones observed had a microdehiscence of the Facial Canal, usually located at the oval window area (74.9%) and found bilaterally 40% of the time. The authors found a 0.48% prevalence (5 out of 1045) of persistent stapedial artery. This is the first histological study of temporal bones to report a prevalence of this vascular anomaly.

Facial Canal anatomy in patients with mandibuloFacial dysostosis comparison with respect to the severities of microtia and middle ear deformity
Otology & Neurotology, 2005Co-Authors: Hideki Takegoshi, Kimitaka Kaga, Yasuhiro ChiharaAbstract:OBJECTIVE: To study the difference in the Facial Canal anatomy in terms of the severity of microtia and deformity of the middle ear in patients with mandibuloFacial dysostosis using high-resolution computed tomography. STUDY DESIGN: Retrospective analyses. SETTING: The study was carried out at the Department of Otorhinolaryngology, University of Tokyo, Tokyo, Japan. PATIENTS: Thirty-six ears of 18 patients with mandibuloFacial dysostosis were examined by high-resolution computed tomography. These ears were graded based on the Marx classification and Jahrsdoerfer scoring systems. MAIN OUTCOME MEASURES: The high-resolution computed tomography findings and age distribution of each group were compared with those of other groups by multiple comparison using Tukey's honestly significant difference test. RESULTS: The course of the Facial nerve was not significantly different in terms of the severity of microtia and deformity of the middle ear. The bony cochlea in the patients with mandibuloFacial dysostosis was displaced by a mean value of 2 mm more anteriorly and a mean value of 0.7 mm shallower than that in the cases with normal auricles. CONCLUSION: The Facial nerve of patients with mandibuloFacial dysostosis is displaced more anterolaterally than that of the cases with normal auricles; however, the auricle anomaly is not severe.

difference in Facial Canal anatomy in terms of severity of microtia and deformity of middle ear in patients with microtia
Laryngoscope, 2003Co-Authors: Hideki Takegoshi, Kimitaka KagaAbstract:Objective To study the difference in the Facial Canal anatomy in terms of the severity of microtia and deformity of the middle ear in patients with microtia using high-resolution computed tomography (HRCT). Study Design Forty-six ears with microtia were examined by HRCT. These ears were graded based on two systems of classification and scoring, respectively. The HRCT findings of each group were compared with those of other groups by multiple comparison using the Tukey honestly significant difference test. Methods Forty-six ears with microtia (unilateral microtia, n = 12; bilateral microtia, n = 34) were examined by HRCT. These ears were graded based on two systems of classification and scoring, respectively. The HRCT findings and age distribution of each group were compared with those of other groups by multiple comparison using the Tukey honestly significant difference test. Results The mastoid portion of the Facial nerve was 3 mm more anteriorly displaced in patients with grades II and III microtia than in those with grade I microtia (P <.01). From the scoring system that was used, the course of the Facial nerve was not significantly different between patients with a score of 5 points or less and those with a score of 6 points or more. Conclusion The mastoid portion of the Facial nerve in patients with grades II and III microtia would be more anteriorly displaced because of hypoplasia of the second genu.
