Study Notes
Histopathologic Studies
- Various studies focus on the nasal septal turbinate (NST) as glandular, erectile tissue.
- Wexler, Elwany, Costa, and Sisman found similar findings regarding NST characteristics across different locations (Middle East, Africa, North America, and Europe) using both living patients and cadaver subjects.
- All studies utilized a prospective design, indicating direct observation of outcome with minimal bias.
- Bias and evidence levels per MINORS and OCEBM criteria indicate varying risks, with most studies scoring low to moderate risk of bias.
Treatment Outcomes
- The NST is observed to decrease in size with age, correlating with inferior turbinate size, highlighting its potential role in nasal airflow and humidification.
- Evidence suggests that larger soft tissue components of the NST may occur in patients with a history of sinonasal allergies.
Methodological Considerations
- Current procedural terminology (CPT) codes exist for septoplasty and inferior turbinate reduction, but no specific code for nasal septal turbinate reduction.
- Majority of studies are retrospective, leading to risks of data inaccuracies and selection bias, especially notable in non-North American studies.
Evidence Variability
- Evaluation of treatment outcomes shows variability in objective tests and metrics used, which could confound results.
- Key literature reveals a prevalent interest in the NST role regarding airflow regulation within the nasal cavity, further research encouraged.
Relevant Studies
- Numerous studies highlight the correlation between septal body size and various health outcomes, including the quality of life based on the Sinonasal Outcome Test (SNOT-20).
- Studies also delve into the link between allergic rhinitis and septal body alterations, coupled with potential treatment implications involving botulinum toxin for rhinitis management.
