Fibro-osseous lesions of the sinonasal tract: a contemporary review

Purpose of reviewFibro-osseous lesions (FOL) are benign, slow-growing lesions that are often incidentally discovered in the sinonasal cavity. They may necessitate surgical resection in patients with postobstructive sinusitis, or in cases of cranial nerve and orbital compression. We examine the recent advancements in otolaryngology relating to diagnostic characteristics and treatments for FOL, with emphasis on new technologies to improve outcomes and reduce recurrence.Recent findingsWe discuss distinguishing characteristics across FOL subtypes, including osteomas, fibrous dysplasia, and ossifying fibroma. Recent literature encompasses clinical case series and animal model studies examining mechanistic, diagnostic, and therapeutic findings in FOL. Recent advancements include emerging pharmacological therapies, development of imaging guidance for surgical planning, and focus on the importance of complete surgical resection for improved outcomes.SummaryManagement of most FOL may be approached by endoscopic techniques, harnessing recent improvements in image guidance and surgical innovation. Improved diagnostic imaging, including the use of 3-D surgical planning, has been shown to enhance treatment outcomes. Improved understanding of the genetic and pathophysiological characteristics of FOL could further reveal targeted therapies, reducing recurrence and improving patient quality of life.
