Analysis of conduction losses in inverters
IET Electric Power Applications, 1995A conduction-loss-evaluation method which is important in inverter design is presented. The method is based on the probability of inverter switching devices receiving ON signals. Since it does not require knowledge of the exact switching patterns of the power devices, the proposed method is especially useful for inverters in which the switching ...

Conductive Hearing Loss in Children
Neuroimaging Clinics of North America, 2023A variety of congenital and acquired disorders result in pediatric conductive hearing loss. Malformations of the external auditory canal are invariably associated with malformations of the middle ear space and ossicles. Isolated ossicular malformations are uncommon.

Unexplained Conductive Hearing Loss
Southern Medical Journal, 1980We report a series of unusual clinical cases which exhibit what we have referred to as unexplained conductive hearing loss. Audiometrically, these cases typically display mild to moderate conductive or mixed-type hearing loss and good word discrimination (80% to 100%). The otologic evaluations also lend support to the audiometric findings.

The Diagnosis of a Conductive Olfactory Loss
The Laryngoscope, 2001AbstractObjectives/Hypothesis Two of the most common causes of olfactory loss include upper respiratory infection (URI) and nasal or sinus disease. The etiology of most URI‐related losses is thought to be viral and, as yet, there is no available treatment.

Posttraumatic Conductive Hearing Loss
Archives of Otolaryngology - Head and Neck Surgery, 1965Introduction POSTTRAUMATIC conductive hearing loss, caused by interruption of the ossicular chain as a result of indirect trauma, has recently been the subject of several reports in the literature (Andersen et al, 1 Escher, 2 Hough 3 ). In the past few years we had occasion to observe 15 cases of this kind in the Utrecht University Clinic.

Congenital conductive hearing loss
The Journal of Laryngology & Otology, 2002Congenital conductive hearing loss due to ossicular deformities can be treated by either rehabilitation with a hearing aid or surgical reconstruction. We present the results of exploratory tympanotomy performed in a large paediatric otolaryngology centre in 67 patients with non-serous congenital conductive hearing loss.

An uncommon cause of conductive hearing loss
American Journal of Otolaryngology, 2020The current video presents the surgical management of a middle ear osteoma through a retroauricolar endocanalar approach, under local anesthesia. The video contains patient's medical history, pre-operative radiological evaluation, surgical approach to the lesion and clinical follow up.

Madelung's Deformity With Conductive Hearing Loss
Archives of Otolaryngology - Head and Neck Surgery, 1970THE dyschondrosteosis of Leri-Weill and the condition known as Madelung's deformity seem to be related entities. 1 Dyschondrosteosis was first described in 1929 in the French literature by Leri and Weill. 2 However, Madelung, a German surgeon, has described the deformity in a patient presented to the seventh congress of surgeons in Germany in 1878. 3 A
