This article presents the endoscopic anatomy of the retrotympanum and its relationship to other important anatomic landmarks in the middle ear to provide understanding of its importance and relevance during surgeries. A well-detailed tour of the retrotympanum, its associated structures, variability of anatomic structures, and surgical relevance is presented.
OBJECTIVES To investigate the anatomic limitations of the endoscopic transcanal approach to sinus tympani (ST), in particular, how this approach might allow a complete visualization of the ST recesses and to propose a morphologic classification of the ST using computed tomography and to examine if this could be useful for the surgeon in preoperative(More)
Comorbidity of vestibular and anxiety disorders was suggested by epidemiological studies and, recently, new insights into potential neural circuits which subserve both balance control and emotions, appear to support this hypothesis. In particular, disorienting visual surroundings, such as those generated by full-field moving scenes, equally disrupt postural(More)
One of the most recent and promising theoretical hypotheses for compensation of persistent asymmetry of dynamic vestibulo-ocular gain is sensory substitution. As a switch between oculomotor and vestibulo-ocular systems, saccadic eye movements are engaged in humans to compensate the angular displacement of the head towards the labyrinthine defective side(More)
The objective of this study is to analyze the possible variations in size and shape of the AER in the ear affected by acquired cholesteatoma versus the healthy ear in the same patient. A total of 22 patients affected by acquired cholesteatoma were included in our study. A CT morphological evaluation of both ears (pathologic and non-pathologic) was made.(More)
As L-type voltage-gated calcium channels (VGCCs) control Ca(2+) influx and depolarisation of cardiac and vascular smooth muscle, they represent a specific therapeutic target for calcium channel blockers (CCBs), which are approved and widely used to treat hypertension, myocardial ischaemia and arrhythmias. L-type currents also play a role in calcium entry in(More)
OBJECTIVES The aim of the present study is to document and analyze the ossicular chain preservation rate in patients affected by acquired primary cholesteatoma with epitympanic involvement and with preoperative intact ossicular chain. STUDY DESIGN A retrospective case series in a tertiary university referral center. METHODS From January 2006 to February(More)
Cancer of the larynx in the intermediate/advanced stage still presents a major challenge in terms of controlling the disease and preserving the organ. Supratracheal partial laryngectomy (STPL) has been described as a function-sparing surgical procedure for laryngeal cancer with sub-glottic extension. The aim of the present multi-institutional study was to(More)
Midline suprasellar meningiomas have traditionally been removed through transcranial approaches. Endoscopic endonasal approaches have already been described for the removal of tuberculum sellae meningiomas (Cook), but their exclusive use for planum sphenoidale meningiomas has never been reported. A case report of a planum sphenoidale meningioma removed(More)
This study aims to define indications for micro-endoscopic laser surgery in early glottic carcinoma (Tis, T1a and T1b), to examine patterns of local recurrences and related retreatment methods. A cohort of 79 patients with previously untreated early glottic carcinoma, subjected to endoscopic CO2 laser excision between January 1993 and October 2000, was(More)
