Abstract:
Allergic fungal sinusitis (AFS) and eosinophilic mucin chronic rhinosinusitis (EMCRS) are subtypes of a chronic rhinosinusitis with eosinophilia that have different diagnostic criteria but are phenotypically similar. Ophthalmic complications may be the presenting symptoms. Treatment of ophthalmic complications is typically directed at reducing the inflammatory burden in the sinuses and rarely requires direct surgical intervention. However, atypical cases with associated subperiosteal abscess may necessitate orbital surgery. The authors present 2 cases of EMCRS with orbital involvement - one that responded to the traditional treatment of oral corticosteroids and functional endoscopic sinus surgery (FESS), and the other requiring surgical drainage of a subperiosteal abscess in order to describe the management strategies based on clinical presentation.
Insights
Allergic fungal sinusitis and eosinophilic mucin chronic rhinosinusitis can cause eye complications. Management depends on presentation, with some cases requiring orbital surgery for subperiosteal abscesses.
Area of Science:
- Otolaryngology
- Ophthalmology
Background:
- Allergic fungal sinusitis (AFS) and eosinophilic mucin chronic rhinosinusitis (EMCRS) are phenotypically similar subtypes of chronic rhinosinusitis with eosinophilia.
- Ophthalmic complications can be the initial presentation for these conditions.
Purpose of the Study:
- To describe management strategies for orbital complications in EMCRS based on clinical presentation.
- To highlight the role of reducing sinus inflammation and potential need for orbital surgery.
Main Methods:
- Case report of two patients with EMCRS and orbital involvement.
- Review of treatment approaches including oral corticosteroids, functional endoscopic sinus surgery (FESS), and surgical drainage of subperiosteal abscess.
Main Results:
- One patient responded to conservative treatment (oral corticosteroids and FESS).
- The second patient required surgical drainage of a subperiosteal abscess for orbital involvement.
Conclusions:
- Management of ophthalmic complications in EMCRS is typically non-surgical, focusing on sinus inflammation.
- Atypical cases with subperiosteal abscesses may necessitate direct orbital surgery.
