Summary
Dominant symphalangism, a rare genetic disorder, was observed in three generations. In a 14-year-old male, this condition caused conductive hearing loss due to stapes fixation.
Area of Science:
- Genetics
- Otolaryngology
- Orthopedics
Background:
- Symphalangism is a congenital disorder characterized by the fusion of bones in the digits.
- This paper investigates the inheritance pattern and clinical manifestations of dominant symphalangism.
- Conductive hearing loss is a potential complication associated with symphalangism.
Observation:
- A family spanning three generations exhibited dominant symphalangism.
- A 14-year-old male patient presented with proximal symphalangism.
- The patient experienced conductive hearing loss.
Findings:
- The conductive hearing loss in the patient was attributed to fixation of the stapes.
- Dominant inheritance pattern confirmed through pedigree analysis.
- Proximal symphalangism linked to auditory ossicle abnormalities.
Implications:
- Highlights the genetic basis and varied expressivity of symphalangism.
- Underscores the importance of audiological evaluation in patients with symphalangism.
- Provides insights into the management of hearing loss in this condition.
