What is appropriate management for the contralateral uninvolved side in unilateral allergic fungal rhinosinusitis?. Issue 1 (15th February 2023) - Bitner, Benjamin F.
Abstract : Purpose of review: The aim of this article is to review the current literature regarding development of new or recurrent inflammation of uninvolved contralateral sinuses in unilateral allergic fungal rhinosinusitis (AFRS) and discuss management strategies. Recent findings: AFRS is a subtype of chronic rhinosinusitis with nasal polyposis (CRSwNP) that can manifest as either unilateral or bilateral disease. Particular to AFRS compared with other CRSwNP subtypes is the high propensity for recurrence. Multiple recent studies have evaluated the recurrence rate of uninvolved contralateral sinuses in unilateral AFRS and demonstrated eventual involvement of the nondiseased side. Additionally, postoperative medical therapy of the nondiseased side reduced recurrence rates overall. Summary: Recurrence of AFRS is high in both the ipsilateral and contralateral sinuses. Upfront bilateral medical and/or surgical treatment of patients presenting with unilateral AFRS may be considered to improve long-term inflammatory control.
