Abstract
KEY POINTS Respiratory epithelial adenomatoid hamartoma (REAH) is easily confused with nasal polyps (NP). The typical manifestation of REAH on CT is the enlargement of bilateral olfactory clefts (OCs). The widening of the OCs in the CT scan is a biomarker for diagnosing REAH associated with NP.

Abstract
Objective Respiratory epithelial adenomatoid hamartoma (REAH) is classified as a histopathologic diagnosis and often identified in sinus surgery for chronic rhinosinusitis (CRS). The purpose of this study was to clarify the frequency and predictors of REAH and prognosis of CRS with REAH in CRS cases. Methods In the first study, we histologically reviewed sinonasal polyps and mucosal tissue specimens obtained from patients who underwent endoscopic sinus surgery (ESS) for CRS to reveal how many REAH were involved in ESS cases. We compared REAH and non‐REAH groups in terms of preoperative symptoms and endoscopic, imaging and blood examination findings to elucidate predictors of REAH genesis. In the second study, we compared the data 3 months after surgery such as endoscopic and imaging findings and olfactory test to evaluate prognosis of CRS with REAH. Results The prevalence of REAH was 15.5% of all 304 cases in the first and second studies combined. Higher polyp score in the middle meatus was an independent predictor of the presence of REAH (p = .02). Presence of REAH was significantly associated with the enlargement of olfactory cleft polyps (p < .01), increasing postoperative scores of standard olfactory tests (p = .03), and decline of ratio of improvement (p < .01) measured using T&T olfactometry. Conclusions Higher polyp score in the middle meatus is an independent predictor of REAH. Olfactory function is difficult to recover after surgery in REAH patients because it is associated with recurrent polyps in the olfactory cleft.
