Incomplete partition-type III anomaly (X-linked deformity) is no common finding in a prospective candidate for cochlear implantation. In this paper, the problems about the cochlear implantation in cases with incomplete partition-type III anomaly (X-linked deformity) and profound sensorineural hearing loss is discussed. High-resolution multidedector computed tomography (MDCT) and magnetic resonance imaging were performed preoperatively in all patients. MDCT revealed that there was bulbous dilatation at the lateral ends of internal auditory canals (IAC) in all patients. There were also enlargements of labyrinthine segments of facial and superior vestibular nerve canals. Patients with the basal turns of cochlea incompletely separated from IAC were also presented. Patients with IP-type III (X-linked deformity) and profound SNHL were implanted. Standard transmastoid-facial recess approach was used and cerebrospinal gusher was encountered after the cochleostomy in all cases. Postoperative performance was very good in all patients. Two patients had complications, which are facial nerve stimulation and device failure. Both patients were reimplanted. Cochlear implantation is a good choice in the patients with IP-type III. However, this anomaly may have special potential risk than the other inner ear abnormalities. Therefore, the surgeon should be aware of them and must be ready to inform the patient and parents.
Fig 1. Well-demarcated tumor mass enclosed by intact mucosa (hematoxylin and eosin stain, original magnification xSO). Schwannomas are uncommon neurogenic tumors, usually solitary, that arise from cells of the neural sheath. The tumors have been reported along most cranial nerves, the sympathetic chain, and brachial plexus. Schwannoma is the most common benign tumor of the pharynx," but schwannoma of the tonsil is an extremely rare tumor. To our knowledge, only 2 cases of a tonsillar schwannoma have been documented, in an adult and a child.t-' Schwannoma occurs equally in both genders, and no causative factors have been identified. Age at onset has ranged from 1 to 89 years, with the majority presenting in the fourth decade of life." Macroscopically, schwannomas are typically circumscribed and encapsulated. They may show cystic degeneration. Histologically, 2 distinct patterns can be seen: known as Antoni type A and type B. Antoni type A tissues are characterized by compact Schwann cells with nuclear palisading, whereas Antoni B tissues exhibit a considerable degree of cell pleomorphism in a loosely arranged reticulum network. Vascularity is not a prominent feature, and necrosis and mitotic activity are seldom encountered. As the schwannoma ages, degenerative changes take place, characterized by hyalinized tissue, myxoid areas, and large 693
The aim of functional septorhinoplasty is to create an esthetically elegant nose and harmony in the face by preserving nasal function as well as maintaining or restoring adequate airway. Since nasal complaints are usually subjective, it may be difficult to evaluate the functions objectively. In the present study, we aimed to investigate the alterations in nasal function associated with septorhinoplasty by using both objective and subjective methods. The study population consisted of 40 patients who underwent septorhinoplasty and 40 healthy controls. Before and after the operation, visual analog scale, acoustic rhinometry, rhinomanometry, and Odiosoft-Rhino test were applied to all patients and controls. There were significant differences in all parameters both before and after the operation. While a significant difference was obtained between the patient and control groups in terms of preoperative values, no significant difference was found between postoperative values of these groups. Both objective and subjective methods are important in evaluations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
