Summary
This study reports the first known cases of ectopic teeth found on the inferior nasal concha (INC) in human skulls. This rare nasal cavity anomaly has significant implications for medical professionals.
Area of Science:
- Anatomy
- Pathology
- Anthropology
Background:
- Ectopic teeth in the nasal cavity are rare but documented.
- No previous reports exist of ectopic teeth specifically on the inferior nasal concha (INC).
Observation:
- Two adult female skulls exhibited an anomalous tooth projecting from the posterior margin of the right inferior nasal concha (INC).
- One skull presented a small, quadrangular tooth extending beyond the hard palate, while the other had a medium-sized conical tooth.
- The affected INC in both specimens were positioned inferiorly and closely approximated the hard palate.
Findings:
- This study presents the first reported instances of ectopic teeth originating from the inferior nasal concha (INC).
- The anomalous teeth varied in size and shape, projecting from the posterior aspect of the INC.
- Associated findings included inferior displacement of the INC and proximity to the hard palate, without other noted deformities.
Implications:
- Understanding this rare anatomical variant is crucial for otorhinolaryngologists, reconstructive surgeons, and dental professionals.
- Accurate identification of ectopic teeth on the INC is vital for diagnosis and management during surgical or radiological procedures.
- This finding contributes to the understanding of dental and craniofacial development and potential evolutionary pathways.
