    Morphometric evaluation of cerebral and cerebellar structures in long-term unilateral sensorineural hearing loss
    (Assoc Brasileira Otorrinolaringologia & Cirurgia Cervicofacial, 2025) Kubat, Gozde Orhan; Ozen, Ozkan; Colak, Emre
    Objective: Structural changes in the brain have been identified in patients with hearing loss. However, the effect of long-term Unilateral Sensorineural Hearing Loss (USNHL) on cerebral and cerebellar morphology is not fully understood. Methods: In this study, Magnetic Resonance Imaging (MRI) of 12 long-term USNHL adults was compared with their Normal-Hearing (NH) side using Voxel-Based Morphometry (VBM). The USNHL group was also compared to a control group of 12 hearing-healthy individuals. Volume and cortical thickness changes in cerebral and cerebellar structures, possibly related to hearing loss severity and duration, were assessed using VBM. Results: The study found that, compared to the control group, USNHL patients had significantly higher measurements in the Frontal Operculum (FO) Gray Matter (GM) volume (cm3) (p = 0.024), Superior Temporal Gyrus (STG) thickness (p = 0.041), and cerebellum IX GM volume (cm3) (p = 0.025). No significant differences were observed between the intact and NH sides in the USNHL group (p > 0.05). Conclusion: Cerebral and cerebellar structures, which are essential for perceiving and interpreting sound, integrating information, and coordinating movement, may undergo morphological changes due to neuroadaptive mechanisms in long-term USNHL patients. Larger case series are needed to explore the clinical implications of these changes for diagnosis, treatment, and prognosis. Levels of evidence: Level 3.

    Retropharyngeal Abscess Presenting as Torticollis
    (Coll Physicians & Surgeons Pakistan, 2022) Kubat, Gozde Orhan; Altindal, Aysegul Sule
    Retropharyngeal abscess (RPA) is a deep neck infection with life-threatening complications such as airway obliteration, necrotizing mediastinitis, and pulmonary empyema, which must be diagnosed early and treated promptly. We herein present a patient who was admitted to the emergency room with limited neck movement, torticollis, difficulty in swallowing, and a feeling that something is stuck in the throat and diagnosed with RPA. Plain lateral radiograph of the neck revealed air levels at the level of C3-C5. Computed tomography (CT) scan confirmed the diagnosis of RPA. After emergency surgery, clinical condition normalised in a short time, and at a 2-week postoperative follow-up, the retropharyngeal area was completely normal on endoscopic examination. It is important to recognise and treat RPA, which has a high mortality due to its complications. RPA should be kept in mind in the differential diagnosis of patients with neck pain and torticollis, particularly in adults.
