Abstract Introduction: external nasal walls are  an important factor  in the drainage or obstruction of the ostiomeatal complex, therfor  anatomical variations in the nasal cavity can elevate the risk of pathological sinus conditions. The aim of this study is to evaluate anatomical variations of paranasal sinuses and nasal cavities using cone beam computed tomography (CBCT). Materials and ...

There have been reports of ulnar nerve compression due to anatomic variations at Guyon’s canal. Knowledge certain canal may help hand surgeons identify possible unconventional sites the nerve. We present a case report patient with an aberrant palmaris brevis muscle belly that was found cross over proximal aspect tunnel neurovascular bundle potentially causing symptoms. Surgical interventions re...

OBJECTIVES The purpose of the present study was to elucidate the significance of cone bean computed tomography (CBCT) for patients hoping to undergo implant-supported restorations of the maxilla. Therefore, two studies were planned. One was to compare the prevalence of anatomic variations and lesions in the maxillary sinus on CBCT of patients hoping to undergo implant-supported restorations of ...

Recently, several new techniques for anatomic posterior cruciate ligament reconstruction (PCLR) have emerged and are believed to restore the normal anatomy of the posterior cruciate ligament more accurately. Despite the latest trend, the optimal methods for anatomic PCLR remain controversial. The purpose of this research is to review surgical techniques for PCLR in cadaver studies and suggest c...

BACKGROUND The sphenopalatine foramen is located on the lateral nasal wall and has multiple variants and anatomic landmarks that are important to know to optimize RESULTS in the surgical management of posterior epistaxis. OBJECTIVE This study describes the endoscopic anatomy of the sphenopalatine foramen, related structures and anatomic variations in a Mexican population. METHODS We perform...

Background: Variations in morphology and metrical values of Gall Bladder (GB) is quite common. These variationsare frequently observed during imaging procedures like laparoscopy cholecystectomy. The anatomicalvariation GB essential to clinician.Method: 48 adult cadavers were studied evaluate the morphometric study GB. size shape wereclassified with percentage. length breadth measured tailors ta...

Background: Chronic rhinosinusitis (CRS) refers to a group of disorders characterized by inflammation of the mucosa of the paranasal sinuses. Computed tomography (CT) scans used as the gold standard diagnostic modality of nose and paranasal sinus diseases. There has been a lot of studies regarding the anatomic variations leading to pathogenesis of paranasal sinus diseases. Considerable progress...

The standard long incision technique for carpal tunnel release causes inevitable damage to skin sensation, the inter-thenar plexus and especially the distal branches of the palmar cutaneous branch of the median nerve (PCM), and may cause long-term disabling pain and scar tenderness. There are many variations in the distal branches of the median nerve at the wrist. Anatomic studies of this regio...

The angiographic anatomy of the external carotid artery system in the rhesus monkey is described. Similarities and differences between human and monkey anatomy are emphasized, as well as anatomic variations and potential collateral pathways. Superselective angiography and embolization in the external carotid artery system of the rhesus monkey proved to be technically feasible and potentially re...

OBJECTIVE Recent reports suggest an increase in oral squamous cell carcinoma (OSCC) frequency. To improve programs in public health, it is necessary to understand the epidemiological conditions. The aim of this study was to analyze the trend in gender, age, anatomic zone and OSCC stage from Mexico City's General Hospital patients from 1990 to 2008. STUDY DESIGN A retrospective review of all O...
