La timpanoplastica aperta: indicazioni e nostri risultati a distanza

2010

OBIETTIVI Le indicazioni per una tecnica aperta sono in primo luogo le otomastoiditi colesteatomatose, le neoplasie, alcune complicanze ed alcune forme di otomastoidite granulomatosa diffusa con totale coinvolgimento della catena ossiculare, specialmente quando esiste una mastoide eburmnea. MATERIALI Nel periodo 1975‐2006 sono state eseguite 4875 timpanoplastiche, di cui 3343 con tecnica aperta. In considerazione dell'esperienza maturata è utile distinguere un periodo compreso tra il 1975 e 1990, nel quale, indipendentemente dalla diagnosi, si eseguiva la tecnica chiusa nel 95% dei casi, mentre la tecnica aperta era riservata al 5% dei casi. Nell'85% delle tecniche chiuse veniva eseguito un…

2006

The Authors propose a multifactorial pattern for the understanding of the psychological development of the child with impaired hearing. According to this pattern the psychological development is determined by a variety of factors that can be regrouped intothree categories: • family features • aspects concerning the rehabilitation and the acoustic prosthesis • social and socio-environmental factors. In order to apply an effective action it is necessary to consider the interaction of the different factors and to adapt the therapeutic plan to that particular situation.

Ewing sarcoma family of tumors: Causes, diagnosis and treatment

2019

The Ewing's sarcoma Family of Tumors (EFT) includes classic Ewing's Sarcoma (ES) of bone, Extraskeletal Ewing's Sarcoma (EES) and malignant peripheral primitive Neuroectodermal Tumor (pNET) of bone and soft tissue. ES is an aggressive tumor with a high incidence of local recurrence and distant metastasis. The skeletal form is more common and typically occurs in the long bones of the extremities. The extra skeletal form occurs in the soft tissues of the lower extremities, paravertebral tissues, chest wall, retroperitoneum and rarely in the head and neck region in about 1-4% of cases. Involvement of the head and neck is usually identified in the nasal or oral cavities, sinuses or soft tissues…

Vascular loops causing otological symptoms and…: esperienza personale

2009

Per conflitto neurovascolare (CNV) si intende la presenza di un contatto tra uno o più nervi cranici nel punto di emergenza dal tronco dell’encefalo e una struttura vascolare, arteriosa o venosa. Tale contatto può configurarsi come una “cross compression”, cioè come una compressione ad angolatura variabile tra le due strutture o come una compressione a “sandwich”, vale a dire un intrappolamento del nervo tra due strutture vascolari. Questo si verifica più frequentemente a livello della root entry zone (REZ), cioè di quella piccola porzione di nervo ubicata nelle immediatezze del tronco encefalico, ancora ricoperta dalla mielina centrale. Il CNV è responsabile dell’insorgenza di diversi quad…

Association between sensorineural hearing loss and sleep-disordered breathing: Literature review

2015

The cochlea is especially sensitive to circulatory alterations because it is supplied by a single terminal artery and lacks adequate collateral blood supply. To examine the putative association between Sensorineural Hearing Loss (SNHL) and Sleep Disordered Breathing (SDB) through the literature review is very interesting. In fact these medical disorders usually are associated to cerebral circulatory alterations resulting in hypoxia, acute hemodynamic change, and decreased cerebral blood flow, because the Sleep Disorder Breathing (SDB), for example OSAHS (Obstructive Sleep Apnea Hypopnea Syndrome), is characterized by periodic hyposia/reoxygenation. These noxious stimuli can, in turn, activa…

Sudden sensorineural hearing loss

2019

Sudden sensorineural hearing loss (SSNHL), is an important otological disorder that affects up to 5-20 in 100,000 people. It is characterized by a rapid loss of the hearing, usually unilateral, with a sensorineural hearing loss greater than 30 dB over three consecutive frequencies, in less than 72 hours and can be associated with tinnitus and vertigo. It is a real sensorineural emergency that can become a permanent handicap if not adequately treated. Because of patients recovering rapidly or seeking no medical attention, the true figure might be higher, even if delaying SHL diagnosis and treatment may decrease the effectiveness of treatment. Sudden Hearing Loss can occur at any age but usua…
