A solitary fibrous tumor (SFT) is an extremely rare, distinct otological soft-tissue tumor. Only two such tumors in the external auditory canal have been reported. A SFT related to hemangiopericytomas (HPC), which commonly arise in the central nervous system. HPCs act malignant in many cases, while SFTs at other sites are mainly benign. A 25-year-old female presented with highly vascular tumor at the right external auditory meatus and bleeding from the mass when a crust was removed from its surface. After excisional biopsy followed by pre-operative embolization, this tumor confirmed with SFT. The recurrence rate of SFT is very low after complete resection, with a slightly increased risk of recurrence with extrathoracic tumors. We describe the third case of SFT in the external auditory canal and review the literature.
A 28-year-old female domestic helper presented to the Ear, Nose, and Throat clinic complaining of three weeks of right otalgia associated with a right blocked ear. The hearing was otherwise normal, and she denied otorrhoea, dizziness or imbalance, ear digging, or water contact, and has no history of ear eczema. She has no other past medical history and no recent travel history.

Unlabelled: () is a neuro-specific gene linked to neurodevelopmental disorders and has recently been reported to function as a bidirectional emotional regulator, highlighting its molecular roles in the nervous system. However, the connections between , brain architecture, and functionality remain to be fully elucidated. Our study utilized 11.
Background: Primary squamous cell carcinoma (SCC) of the middle ear is rare, with non-keratinizing basaloid types being exceptionally uncommon. Distinguishing these cancers, often caused by viral factors (, human papillomavirus or Epstein-Barr virus), or specific genetic alterations (, bromodomain-containing protein 4-nuclear protein in or gene fused with FLI chromosomal rearrangement), from other cranial conditions, is difficult. The recently identified DEK::AFF2 non-keratinizing SCC (NKSCC) is a novel subtype, fitting the World Health Organization classification of head and neck neoplasms.
Introduction: External ear malformations represent a spectrum of congenital anomalies that may involve the external auditory canal (EAC), tympanic membrane (TM), or associated structures. A rare anomaly, the EAC skin wedge, results from incomplete canalization during embryologic development. This report presents the clinical presentation, diagnostic evaluation, and surgical management of this condition.
Rhythm perception and synchronization to periodicity hold fundamental neurodevelopmental importance for language acquisition, musical behavior, and social communication. Rhythm is omnipresent in the fetal auditory world and newborns demonstrate sensitivity to auditory rhythmic cues. During the last trimester of gestation, the brain begins to respond to auditory stimulation and to code the auditory environment.
