Aneurysmal bone cysts (ABCs) are benign, nonneoplastic, hemorrhagic, and expansile osseous lesions that present most frequently at age younger than 20 years. Aneurysmal bone cysts typically involve long bones of extremities, thorax, pelvis, or spinal column. Skull base involvement is very rare. The authors report the case of a 23-year-old woman with ABC of the skull base and total removal of lesion with pure endoscopic endonasal approach. The patient had presented with nasal obstruction for 6 months. Physical and neurological examination findings were normal except for bilateral anosmia. Cranial magnetic resonance imaging (MRI) revealed a tumor occupying ethmoid sinuses anterior skull base that extended into bilateral frontal lobes. The patient underwent pure endoscopic endonasal surgery, and the tumor was resected gross-totally. Histologic examination revealed ABC. Consequently, ABC should be considered in differential diagnosis of skull base pathologies. Endoscopic endonasal surgical approach is a safe, minimally invasive, and effective way in the treatment of these tumors.
Patients and providers vary in how they describe common otolaryngology-related complaints. These differences can lead to miscommunication and frustration that may affect patient outcomes and satisfaction. The aim of this cross-sectional survey-based study was to explore the differences in migraine symptom selection by otolaryngology patients and clinicians.
DEK::AFF2 fusion nonkeratinizing squamous cell carcinoma (NKSCC) is an emerging entity in the sinonasal tract, temporal bone, and skull base. However, the clinical behavior of these tumors has not been well studied. Here, we report the largest cohort of DEK::AFF2 carcinomas to determine if morphology, mitotic rate, and/or Ki-67 IHC are associated with patient outcomes, including a comparison with high-risk human papillomavirus (HPV)-associated and independent patients.
Purpose: Necrotizing otitis externa (NOE) is a serious life-threatening infection, with Pseudomonas (PA) aeruginosa being the primary causative agent. Over the last two decades the use of systemic anti-PA antibiotics expanded substantially and are now prescribed regularly by physicians. Meanwhile, studies indicate shifting trends in the incidence of the offending pathogen in NOE.
Objectives: To investigate the characteristics of the vascular pedicle of the nasoseptal flap (NSF) and its perfusion patterns using intraoperative indocyanine green (ICG) angiography during endoscopic skull base surgery (ESBS), and examine the correlation between ICG perfusion patterns and clinical outcomes, including postoperative cerebrospinal fluid (CSF) leak and flap necrosis.
Methods: This study enrolled patients undergoing ESBS between January 2017 and December 2021. Intraoperative ICG angiography was performed to visualize the arterial supply of the nasal septum and evaluate NSF perfusion.
Objective: This study aims to summarize the clinical characteristics of skull base osteoradionecrosis (ORN) with the internal carotid artery (ICA) involvement and to distill the key surgical techniques that can enhance the protective measures for ICA.
Methods: We conducted a retrospective, observational study over a six-year period from February 2017 to May 2023. We included patients who were diagnosed with osteoradionecrosis with invasion of the internal carotid artery and collected their demographic information, pathology results, complication rates, ect.
