Vestibular function after simultaneous bilateral cochlear implantation in adults

IntroductionBinaural hearing enhances speech intelligibility, source localization, and speech comprehension in noisy environments. Although bilateral cochlear implantation (CI) offers several benefits, concerns arise regarding the risk of bilateral postoperative vestibular dysfunction with simultaneous CI. This study aimed to longitudinally evaluate changes in vestibular function in adult patients who underwent simultaneous bilateral CI using minimally invasive electrodes and surgical techniques.MethodsA retrospective review was conducted on 10 patients who underwent simultaneous bilateral CI at our hospital. Vertigo symptoms and vestibular function test results were examined preoperatively, 1–6 months postoperatively, and 1 year postoperatively. Nystagmus tests, caloric reflex tests, vestibular evoked myogenic potentials (VEMP) measurements, and static stabilometry were performed as vestibular function tests.ResultsAlthough an initial transient decline in vestibular function was observed, no significant long-term decline was observed in the caloric reflex test, ocular VEMP (oVEMP), or cervical VEMP (cVEMP). Moreover, regardless of the presence or absence of abnormalities in caloric reflex, oVEMP, or cVEMP, no significant deterioration was detected in the static stabilometer test. While two patients reported preoperative dizziness, all patients were symptom-free 1 year postoperatively.DiscussionThe findings suggest that using current minimally invasive electrodes and surgical techniques in simultaneous bilateral CI leads to temporary vestibular function decline postoperatively. However, most patients experience a recovery in function over time, highlighting the potential safety and efficacy of the procedure. Simultaneous bilateral CI surgery is viable, depending on the patient’s auditory needs and burden

Mucosa-associated lymphoid tissue lymphoma of parotid gland with involvement of subglottis and trachea

Although it is well recognized that the salivary glands may acquire Mucosa-associated lymphoid tissue (MALT) lymphoma as a result of Sjögren syndrome (SS), involvements of subglottis and trachea are rare. A 78-year-old woman was referred to our hospital for an enlarged mass of the right parotid area with a history of SS for 7 months. Two weeks after the first visit, she presented with the complaint of stridor and difficulty in breathing. Laryngoscopy revealed the stricture of subglottic space due to the nodular submucosal mass. She was emergently admitted and underwent tracheostomy. Biopsies of the tracheal mucosa and subglottic nodular submucosal mass were pathologically diagnosed as MALT lymphoma. After 6 courses of rituximab plus CHOP (R-CHOP), all lesions disappeared and tracheal stoma were successfully closed. Although MALT lymphoma of upper respiratory tract is extremely rare, respiratory tract should be examined in the patients of parotid lymphoma associated with SS

Successful Management of Aggressive Fibromatosis of the Neck: A Case Report

Background: Aggressive fibromatoses are histologically benign fibrous neoplasms originating from musculoaponeurotic structures throughout the body. They are locally invasive and erode adjacent vital structures. The head and neck region constitutes 7-25% of all extra-abdominal cases. Case Report: Here, we report the case of a patient with aggressive fibromatosis in the left side of the neck. While the tumor deeply invaded the scalene muscles, the lesion was successfully treated by surgery followed by radiotherapy. The patient has been disease free for the last 7 years following treatment. Conclusion: Due to its unusual location in the head and neck region, aggressive fibromatosis should be considered in the differential diagnosis of invading lesions of the neck
