  • Middle Ear osteoma causing progressive facial nerve weakness a case report
    Journal of Medical Case Reports, 2014
    Co-Authors: Kate Curtis, Manohar Bance, Michael D Carter, Paul Hong
    Abstract:

    Facial nerve weakness is most commonly due to Bell’s palsy or cerebrovascular accidents. Rarely, Middle Ear Tumor presents with facial nerve dysfunction. We report a very unusual case of Middle Ear osteoma in a 49-yEar-old Caucasian woman causing progressive facial nerve deficit. A subtle Middle Ear lesion was observed on otoscopy and computed tomographic images demonstrated an osseous Middle Ear Tumor. Complete surgical excision resulted in the partial recovery of facial nerve function. Facial nerve dysfunction is rarely caused by Middle Ear Tumors. The weakness is typically due to a compressive effect on the Middle Ear portion of the facial nerve. Early recognition is crucial since removal of these lesions may lead to the recuperation of facial nerve function.

  • Piezosurgery in the excision of Middle-Ear Tumors: effects on mineralized and non-mineralized tissues.
    Medical Science Monitor, 2007
    Co-Authors: Angelo Salami, Massimo Dellepiane, Francesco Antonio Salzano, Renzo Mora
    Abstract:

    BACKGROUND Piezosurgery is a new instrument able to cut bone without necrosis and non-mineralized tissue damage. The aim of this study was to test the Piezosurgery as a new and alternative method for the excision of Middle-Ear Tumors and to analyze its effects on soft tissues. MATERIAL/METHODS The Piezosurgery device was used to excise eight glomus tympanicum Tumors and two primary B-cell lymphomas of the Middle Ear. The piezoelectric device uses low-frequency ultrasonic waves (24.7-29.5 kHz); the applied power can be modulated between 2.8 and 16 W and is programmed in accordance to the density of the bone. The equipment consists of two hand-pieces, two inserts, and two peristaltic pumps. The microvibrations that are created in the piezoelectric hand-piece cause the inserts to vibrate linEarly by between 60 and 210 microm. RESULTS Piezosurgery provided excellent control in all the patients, without bleeding and harmful effects on the adjacent structures of the Middle and inner Ear. CONCLUSIONS Piezosurgery is a new and revolutionary osteotomy technique utilizing the microvibrations of scalpels at ultrasonic frequency, so that soft tissue will not be damaged even upon accidental contact with the cutting tip. The vibration frequency of Piezosurgery is optimal for mineralized tissue and does not cut the adjacent soft tissue, minimizing the risk of harming the adjacent tissues. This renders the piezoelectric device ideal for application at the border between hard and soft tissues as in the excision of a Middle-Ear Tumor.

  • papillary endolymphatic sac Tumor a case report
    Case reports in otolaryngology, 2012
    Co-Authors: S Arava, R M Soumya, S Chitragar, R Safaya, S H Chandrashekhar, Alok Thakar
    Abstract:

    Glandular Tumors involving the Middle Ear are rare and distinguishing between adenoma and adenocarcinoma remains difficult. A distinct subclass of these Tumors demonstrates microscopic papillary architecture and has a propensity to erode the petrous bone and extend intracranially. The term “aggressive papillary Middle Ear Tumor” has recently been proposed to describe this more invasive type of Middle Ear Tumor. These Tumors cause symptoms even when microscopic in size. Although histologically benign, they have been locally destructive with frequent intracranial extension and patients may die of uncontrolled local disease. These Tumors do not metastasize but there is single case report of drop metastasis to the spine in the literature. Hence this Tumor must be distinguished from other benign Tumors of the Middle Ear. These rare neoplasms constitute a distinct pathological entity and deserve wider recognition.

  • Aetiological profile of facial nerve palsy in north central Nigeria
    'African Journals Online (AJOL)', 2016
    Co-Authors: Afolabi O.a., Alab B.s., Lasisi O.a.
    Abstract:

    Background: Facial nerve abnormalities represent a broad spectrum of lesions which are commonly seen by the otolaryngologist. The aim of this paper is to highlight the aetiologic profile of facial nerve palsy.Methods: A retrospective study of patients with facial nerve palsy seen in the Ear, Nose and Throat clinic for 5 yEars.Results: The study comprised of 25 patients, made of 16(64%) males and 9(36%) females (M:F = 1.7:1). The age ranged between 6months and 80yEars, mean of 32.1yEars (SD=16.38), with peak presentation seen in the 30-40yEars age group. Bell’s palsy 13(52%), road traffic injury 5(20%) and chronic suppurative otitis media 3(12%) are the commonest cause. The others are stroke 2(8%), measles infection 1(4%) and Middle Ear Tumor 1(4%). Spontaneous recovery was observed in 40%.Conclusion: Bell’s palsy was the commonest cause of facial nerve palsy, however aetiologies cut across all age groups. male slightly more affected. This serves as data base for clinical evaluation of facial palsy in our environment
