Lateral cervical anomaliew and salivary heterotopia
Clinical Otolaryngology and Allied Sciences
|June 1, 1979
Summary
Lateral cervical fistulas and cysts may originate from branchial arch remnants. However, salivary tissue was found in many fistulas, suggesting a different origin for these congenital neck anomalies.
Area of Science:
- Otolaryngology
- Developmental Biology
- Surgical Pathology
Background:
- Lateral cervical fistulas typically arise from second branchial arch remnants.
- Lateral cervical cysts are theorized to develop from the branchial apparatus or lymph node inclusions.
Purpose of the Study:
- To investigate the prevalence of salivary tissue in lateral cervical fistulas and cysts.
- To compare the histogenesis of lateral cervical fistulas and cysts.
Main Methods:
- Histological examination of 24 lateral cervical fistulas and 17 lateral cervical cysts.
- Analysis of tissue samples for the presence of salivary tissue.
Main Results:
- Salivary tissue was identified in 9 of 24 fistulas (37.5%), with 5 cases diagnosed as congenital cervical salivary sinus.
- Salivary heterotopia was found in only 1 of 17 cysts (5.9%).
Conclusions:
- Salivary tissue is more common in the lateral neck than previously recognized.
- Lateral cervical fistulas and cysts likely have distinct histogenetic pathways, with fistulas potentially originating from salivary tissue inclusions.
