A newly identified "cochlear cleft" in the otic capsule is frequently observed in pediatric temporal bone CT scans. This finding, potentially the fissula ante fenestram, appears to decrease in incidence with age.

Area of Science:

  • Radiology
  • Anatomy
  • Otology

Background:

  • Advances in temporal bone CT imaging allow high-magnification analysis.
  • An unfamiliar structure, termed the
  • cochlear cleft,
  • was identified in the otic capsule.
  • This represents the first description of this structure in medical imaging literature.

Purpose of the Study:

  • To describe the
  • cochlear cleft,
  • a newly identified structure in the otic capsule.
  • To determine the incidence of cochlear clefts in pediatric temporal bone CT scans.
  • To investigate the relationship between age and the incidence of cochlear clefts.

Main Methods:

  • Temporal bone CT scans from 100 pediatric patients without sensorineural hearing loss were reviewed.

  • The presence of cochlear clefts was assessed.
  • Incidence and age-related prevalence were analyzed.

    • Main Results:

    • Cochlear clefts were identified in 41% of the pediatric subjects.
    • The incidence of cochlear clefts demonstrated a decrease with increasing age.

    Conclusions:

    • A cleft in the otic capsule, the
    • cochlear cleft,
    • , is frequently visualized on magnified temporal bone CT.
    • This structure may represent the fissula ante fenestram.
    • The findings highlight a common anatomical variation in pediatric temporal bone imaging.
