The Impact of Endoscopic Endonasal Skull Base Surgery on Olfaction

Study Purpose

In this study, the research team will investigate the incidence and etiology of olfactory dysfunction following endoscopic endonasal skull base surgery, by combining clinical assessments with histomolecular analysis.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Observational
Eligible Ages	18 Years - 70 Years
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- Adult patients scheduled for endoscopic endonasal skull base surgery.

Exclusion Criteria:

- Pre-existing anosmia.

- Patients has a history of previous endoscopic endonasal skull base surgery

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT06874426
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

The incidence of olfactory dysfunction following endoscopic endonasal skull base surgery remains unclear in current research, and the results vary widely. Additionally, the pathophysiology of this postoperative olfactory dysfunction and the impact of this surgery on the trigeminal system has not been investigated to date. In this study, the investigators developed a state-of-the-art clinical pipeline with olfactory and trigeminal assessments, prior to and following endoscopic endonasal skull base surgery. Furthermore, the investigators will collect surgical waste tissue from the posterior septal mucosa, which is removed during this procedure to gain access to the sphenoid sinus and the (para)sellar region. By performing histomolecular analysis, the research group aims to elucidate the pathophysiology of olfactory dysfunction following this surgery.
