Purpose: To analyse the degree of pneumatisation of the temporal bone when there is an association between dehiscence of the superior semicircular canal and dehiscence of the tegmen tympani.
Materials And Methods: We analysed a retrospective CT study of 124 selected cases. A single inclusion criterion was applied: the presence of a dehiscence of the tegmen tympani.
Renal vascularization is classically described as a renal artery and vein. However, this vascular pattern presents numerous anatomical variations in terms of their number, origin and course due to ontogenetic alterations. The aim was to carry out a descriptive study of the renal vascular pattern observed during the dissection of cadavers intended for teaching purposes.

This article presents a study on the development of an arterial solidifying technique that can be applied to analyze arterial circulation, consequently easing the handling and later diagnosis of diseases in this anatomical site.

The present study examined the correlations between the presence of dehiscences and thickness of the bone covering the SSC and the roof of the glenoid fossa (RGF).
Study Design: Computed tomography was used in a cross-sectional analysis of the presence of dehiscences and thickness of the bone overlying the SCC and RGF in 156 temporal bones of 78 patients.
Objective: Tonsillectomy is one of the surgical techniques most practiced by otolaryngologists, and despite being a relatively simple technique; it presents a considerable percentage of complications, such as postoperative bleeding. The aim of this study is to describe the surgical indications and most frequent complications, analyze whether surgical suture of the tonsillar pillars has an influence on bleeding, and study the data of hospital stay and its importance for the control of complications.
Methods: A retrospective study of 326 patients who underwent a tonsillectomy in our Department of Otolaryngology from 2006 to 2014 was conducted.

Midline destructive lesions have multiple possible etiologies, which can be grouped into neoplastic, infectious, or vasculitis-associated. The purpose of these case reports and literature review was to highlight the need to include mucocutaneous leishmaniasis in the diagnosis of midfacial lesions in any patient who has lived in Leishmania-endemic areas because this entity meets all of the clinical criteria to be considered a form of midline destructive lesion. We present two cases of mucocutaneous leishmaniasis that occurred in a Bolivian male immigrant and a European male traveler to Panama, in whom lesions were misdiagnosed as different midline destructive lesions with different causes (Wegener, vasculitis, and natural killer or T-cell lymphoma [NKTL]).

In 1998 a new cause of vertigo associated with a structural anomaly was reported: superior semicircular canal dehiscence. This condition causes vestibular and auditory disorders, which are frequently associated, and a well-directed medical history allows a suspected diagnosis to be reached: the subject may suffer from vertigo triggered by loud sounds (Tullio's phenomenon) and by changes in pressure within the ear or in the intracranial space, when Valsalva's manoeuvres are performed or on pressing on the tragus (Hennebert's sign).

Introduction And Objective: The aetiology of the superior semicircular canal dehiscence is currently unknown. Our objective was to analyse and discuss different hypotheses about the origin of this pathology.
Methods: In this study performed on 295 temporal bones, one case of partial alteration of the bony roof in the right superior semicircular canal was described from the anatomical and radiological points of view, and compared with the temporal bone on the other side.
At the time of birth, the incudo-mallear joint is completely developed. OBJECTIVE. To study the development of the incudo-mallear joint in human embryos and fetuses.

Objective: To investigate the presence of connections between the bone marrow of the ossicles and the mesenchyme that fills the future tympanic cavity.
Material And Methods: Ninety temporal bones from embryos and foetuses were examined, selecting 15 aged between 20th to 30th weeks of development, to show connections between ossicle marrow and mesenchyme.
Results: The connections are transitory and appear in the malleus and the incus between 20th to 24th weeks of development, while in the stapes appear later, being between 24th to 28th weeks.
Objective: Presenting the first case of superior semicircular canal dehiscence syndrome in the Spanish literature and to establish, using embryological studies, the period in wich superior semicircular canal dehiscence originates.
Material And Methods: 52 embryos and foetuses, from 6 mm to foetal maturity, were studied. The case of a patient suffering from superior semicircular canal dehiscence syndrome is presented.
Introduction: The study of the structure in the arterial wall has been essential to use vessels in the coronary and cerebral bypass. The superficial temporal artery, owing to its high elastic content and its topography, close to the middle cerebral artery, has made possible the revascularization surgery in cerebral areas with ischemia. AIM.

We have studied the development of the tympanic ossicles in 40 embryo-foetal human series aged between 32 days (6 mm) and newborn. Once performed the measurements to date chronologically embryos and foetuses, we did a meticulous dissection of temporal bones. After fix in 10% formol, decalcified with 2% nitric acid, embedded in Paraplast, sectioned in a sequence of 7 mm, and stained with Martin's trichrome.

For that purpose 25 temporal bones of human foetus, aged from 36 days (14 mm) to 29 weeks (270 mm) were analyzed. Samples were fixed in a 10% formaldehyde solution, decalcified with 2% nitric acid, embedded in Paraplast, cut in sections of 7 microns thick and stained with Martin's trichrome method.
