Patients who have had middle-ear or mastoid surgery are at an increased risk of developing cerebrospinal fluid (CSF) otorrhoea. The CSF leak is usually from defects in the tegmen or posterior cranial fossa. We present a patient with CSF otorrhoea following a modified radical mastoidectomy seven years ago. There was an unusual communication between the internal auditory meatus (IAM) and the midd...
مقدمه در ارتدنسی آنالیزهای سفالومتری متعددی مورد استفاده قرار میگیرد کههیچکدام به تنهایی پاسخگوی همه خواستههای تشخیصی و تفسیری نمیباشند. لذا ارائه روشی که در عین سادگی و راحتی در بکارگیری، اطلاعات بیشتری را در اختیار ارتودنتیستقرار دهد حائز اهمیت فراوان است. مطالعه حاضر جهت ارائه چنین هدفی انجام گردید. مواد و روشها اینمطالعه برروی سفالوگرام جانبی 5...
Tumours of the cerebellopontine angle (CPA) account for 5% to 10% of all intracranial neoplasms. Various surgical approaches are possible for providing access to tumours of the CPA. The retrosigmoid approach to the posterior cranial fossa is the latest of numerous modifications of the classic suboccipital approach originally popularized by Harvey Cushing. The aim of this review is to discuss th...
The intercondylar fossa (ICF) indices can be used to evaluate fossa geometry, which may in turn affect the function, pathology and intracapsular surgical repair of the cranial cruciate ligament. The measurements of digital images of the distal femur of 44 dogs were used to calculate the fossa width, shape, height and area indices. The mean values of fossa width index were found to be 0.19, 0.28...
Eleven patients with intractable trigeminal neuralgia were treated by posterior fossa microvascular decompression. Complete pain relief was achieved in 7 patients (63.3%). Partial relief of symptoms was noted in 3 patients (27%). There was no operative mortality. Two patients developed transient lower cranial nerve palsies whereas one patient developed a CSF leak, requiring treatment by lumbar ...
In the present study, eight specimens of sheep (>1 year) of both sexes were dissected to provide a comprehensive description of the weight, allocation and nerve branches of the cranial cervical ganglion. The cranial cervical ganglion was found beneath the mandibular salivary gland. It was located ventromedial to tympanic bulla and ventrally to atlantic fossa. In three out of eight animals it wa...
The anterior, middle and the posterior clinoid processes are located in the middle cranial fossa of the skull. The posterior boundary of the pituitary fossa is formed by the dorsum sellae, the supero-lateral angles of which are raised to form the posterior clinoid process. Unlike the anterior clinoid process, the posterior clinoid process has received less attention in past research studies. Th...
