conclusions among anatomic variations, septal deviation and concha bullosa are predisposing factors for chronic sinusitis and we recommend that patients with chronic sinusitis be treated by surgical procedures. background identifying predisposing factors for chronic sinusitis is very important. objectives anatomical variation of the lateral nasal wall has been investigated in several studies an...

OBJECTIVES The aim of this retrospective study was twofold: (1) to show the role of multi-detector computed tomography angiography (MDCTA) in the evaluation of intracranial arterial anatomic variations; (2) to highlight their clinical importance with illustrated example cases. MATERIALS AND METHODS One thousand seven hundred thirty-nine patients who underwent carotid and/or cerebral CTA using...

A mandibular second premolar with four canals is an interesting example of anatomic variations. This report describes a case of a mandibular second premolar with three roots and four canals (one mesiobuccal, two distobuccal and one lingual). The canals were prepared using K-files and irrigated with NaOCl (5.25%) and normal saline as the final irrigant. The canals were filled laterally with gutt...

The chorda tympani is an important anatomical structure in the tympanic cavity. It may have some anatomic variations. Its anatomic variations are of interest in certain otologic surgical procedures. There are limited reports in the literature about the variations of the chorda tympani. A 49-year-old female patient was refered to our clinic because of conductive hearing loss and tympanic membran...

Improvements in functional endoscopic sinus surgery (FESS) and computed tomography (CT) have concurrently increased interest in the anatomy of the paranasal region. Common anatomical variations are not rare in patients with chronic paranasal sinusitis. The aim of this retrospective study was to analyze the incidence of anatomic variations of the lateral nasal wall in a series of 200 patients wi...
