Summary

Congenital arhinia, a rare condition, was observed in a 9-year-old without surgical intervention. This case highlights the importance of functional evaluation in managing congenital arhinia and associated facial anomalies.

Area of Science:

  • Medical case reporting
  • Pediatric genetics
  • Craniofacial anomalies

Background:

  • Congenital arhinia is an extremely rare congenital anomaly characterized by the complete absence of the nose.
  • This case report details an unusual presentation of congenital arhinia in a 9-year-old, managed without surgical intervention.

Observation:

  • Imaging revealed complete absence of nasal bones, septum, and turbinates, along with maxillary hypoplasia and a high-arched palate.
  • Absence of olfactory bulbs and tracts was confirmed by MRI, leading to anosmia.
  • The patient exhibited normal chromosomal analysis, polysomnography, and intelligence test results, with mild conductive hearing loss and rhinophonia clausa.

Findings:

  • The study presents a unique case of congenital arhinia with significant craniofacial anomalies.

  • Despite the absence of nasal structures and olfactory function, the patient demonstrated normal psychomotor development and no life-threatening complications.
  • Functional evaluations, including hearing and phonetic assessments, provided insights into the patient's condition.

    • Implications:

    • This case underscores the possibility of long-term follow-up and functional evaluation in congenital arhinia patients without severe complications.
    • The findings suggest a potential failure of medial and lateral nasal processes during embryonic development as the underlying pathogenesis.
    • Understanding the developmental etiology is crucial for potential future interventions and genetic counseling.
