Serrated Inferior Turbinate Variation and Sinonasal Findings on CBCT

105 participantsStarted 2026-07-15

Plain-language summary

regulate nasal airflow, humidify and filter inspired air. Serrated inferior turbinate is a rare anatomical variation characterized by an irregular, serrated appearance of the inferior turbinate bone. Although this variation has been described in radiological studies, its possible relationship with maxillary sinus mucosal changes and other sinonasal anatomical features remains unclear. This retrospective observational study aims to evaluate the relationship between serrated inferior turbinate variation and maxillary sinus mucosal thickness, mucosal abnormalities, and other sinonasal anatomical structures using cone-beam computed tomography (CBCT) images. CBCT images obtained from patients who underwent imaging for routine diagnostic purposes will be retrospectively reviewed. The presence of serrated inferior turbinate variation, maxillary sinus findings, inferior turbinate measurements, and nasal septum characteristics will be evaluated. The study aims to improve understanding of the radiological significance of serrated inferior turbinate variation and to provide information that may contribute to more accurate evaluation and reporting of sinonasal anatomical variations.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Individuals aged 18-75 years. * Patients who underwent cone-beam computed tomography (CBCT) imaging for routine diagnostic purposes between January 2025 and June 2026. * CBCT images including both maxillary sinuses, nasal cavity, ostiomeatal complex, and inferior turbinates. * CBCT images with sufficient diagnostic quality and clearly visible anatomical boundaries for evaluation and measurements. * CBCT images in which the anatomical landmarks required for nasal septal deviation angle measurement (crista galli, maxillary spine, and the most deviated point of the nasal septum) can be clearly identified. Exclusion Criteria: * Patients with maxillofacial trauma, fractures, or conditions affecting the midface anatomy. * Patients with congenital craniofacial anomalies (e.g., cleft lip and palate) or syndromes affecting facial anatomy. * Patients with a history of sinonasal, inferior turbinate, or maxillary sinus surgery. * CBCT images with insufficient diagnostic quality, motion artifacts, or metal artifacts preventing accurate evaluation. * Patients with pathological lesions affecting the maxillary sinus or nasal cavity anatomy, including cysts, tumors, or aggressive inflammatory lesions. * CBCT findings suggestive of fungal sinusitis, including heterogeneous hyperdense contents, calcifications, bone expansion, or invasive changes.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
