Persistent challenges in pituitary surgery include the detection of small microadenomas, difficulty in discerning residual tumor from normal gland, and infiltrative adenomas. Although standard perioperative diagnostics include magnetic resonance imaging (MRI), computed tomography, ultrasound imaging, and neuronavigation, some centers employ intraoperative MRI, ultrasound, and fluorescence-guided endoscopy to increase the rate of gross total resection and preserve pituitary function. However, these techniques are often limited by availability, time requirements, cost, and inability to provide histological diagnosis.AimThis review addresses opportunities to optimize both the extent of resection and gland preservation in pituitary adenoma procedures. We discuss the existing constraints faced in pituitary surgery and showcase the current and emerging detection techniques employed in clinical practice, as well as their limitations. We also discuss newer probing approaches such as elastography and Raman spectroscopy.ApproachWe outline key attributes for an ideal optical tool, considering surgical theater functionality, ergonomics, and result reliability and accuracy.ResultsA case study is presented describing the recent development of a fiber-optics instrument specifically designed for endonasal applications based on clinical requirements, along with preliminary data supporting the feasibility of intraoperative implementation.ConclusionsCurrent imaging and navigation tools, although invaluable, have inherent limitations in resolution, integration, and molecular specificity. Raman spectroscopy offers a promising, label-free method for real-time tissue identification, especially when integrated into fiber-optic probes for endonasal use. As a complementary tool, it could enhance intraoperative decision-making and surgical precision. Further clinical validation is needed to support its integration into standard workflows.<\/jats:p>","DOI":"10.1117\/1.jbo.30.8.080901","type":"journal-article","created":{"date-parts":[[2025,8,13]],"date-time":"2025-08-13T08:03:28Z","timestamp":1755072208000},"page":"1-21","source":"Crossref","is-referenced-by-count":7,"title":["Challenges and opportunities for new intraoperative optical techniques in the surgical treatment of pituitary adenomas: a review"],"prefix":"10.1117","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9141-4692","authenticated-orcid":false,"given":"F\u00e9lix","family":"Janelle","sequence":"first","affiliation":[{"name":"University of Montreal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-1551-7331","authenticated-orcid":false,"given":"Victor","family":"Blanquez-Yeste","sequence":"additional","affiliation":[{"name":"Polytechnique Montr\u00e9al"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4251-7804","authenticated-orcid":false,"given":"Trang","family":"Tran","sequence":"additional","affiliation":[{"name":"Polytechnique Montr\u00e9al"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdelhakim","family":"Khellaf","sequence":"additional","affiliation":[{"name":"University of Montreal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Romain","family":"Cayrol","sequence":"additional","affiliation":[{"name":"University of Montreal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catherine","family":"Beauregard","sequence":"additional","affiliation":[{"name":"University of Montreal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e9","family":"Lacroix","sequence":"additional","affiliation":[{"name":"University of Montreal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander G.","family":"Weil","sequence":"additional","affiliation":[{"name":"University of Montreal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippe","family":"Lavigne","sequence":"additional","affiliation":[{"name":"University of Montreal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8154-4952","authenticated-orcid":false,"given":"Fr\u00e9d\u00e9ric","family":"Leblond","sequence":"additional","affiliation":[{"name":"Polytechnique Montr\u00e9al"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moujahed","family":"Labidi","sequence":"additional","affiliation":[{"name":"University of Montreal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"189","container-title":["Journal of Biomedical Optics"],"original-title":[],"link":[{"URL":"https:\/\/www.spiedigitallibrary.org\/journals\/journal-of-biomedical-optics\/volume-30\/issue-08\/080901\/Challenges-and-opportunities-for-new-intraoperative-optical-techniques-in-the\/10.1117\/1.JBO.30.8.080901.full","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T23:00:53Z","timestamp":1790204453000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.spiedigitallibrary.org\/journals\/journal-of-biomedical-optics\/volume-30\/issue-08\/080901\/Challenges-and-opportunities-for-new-intraoperative-optical-techniques-in-the\/10.1117\/1.JBO.30.8.080901.full"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,8,13]]},"references-count":0,"journal-issue":{"issue":"08","published-online":{"date-parts":[[2025,8,1]]}},"URL":"https:\/\/doi.org\/10.1117\/1.jbo.30.8.080901","relation":{},"ISSN":["1083-3668","1560-2281"],"issn-type":[{"value":"1083-3668","type":"print"},{"value":"1560-2281","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,8,13]]}}}
