BACKGROUND: Fungal rhinosinusitis is a common disease of the paranasal sinuses. The fungus ball (FB) is defined as an extramucosal mycotic proliferation that fills one or more paranasal sinuses. Sphenoid sinus is an uncommon localization of this disease, as reported in the literature. This study describes our experience in the diagnosis and treatment of sphenoid sinus FB (SSFB), with a particular focus on the surgical approach to the sphenoid sinus. METHODS: We retrospectively analyzed the clinical records of patients affected by FB of the sphenoid sinus, who underwent endoscopic sinus surgery (ESS) in our institutions between 1995 and 2009. We described the surgical technique, the methods of mycological and histopathological evaluation, as well as the perioperative and postoperative management. RESULTS: From 1995 to 2009, 226 patients affected by sinonasal FB underwent ESS in our institutions. A sphenoid localization was found in 56 patients (24.78%; mean age, 62 years). Cephalea was the most common symptom, and 14.3% of patients complained of ocular symptoms. We performed a direct paraseptal sphenoidotomy in 31 patients (55.4%) and a transethmoidal sphenoidotomy in 25 patients (44.6%). Histology unveiled fungal hyphae with absent mucosal invasion in all cases. Cultural results revealed positivity for mycotic colonization in 26 cases (46.4%, most commonly Aspergillus fumigatus). Follow-up ranged from 12 to 181 months with a mean of 70.7 months. CONCLUSION: The description of our experience in the diagnosis and treatment of SSFB underlines the importance of a precise diagnostic pathway in case of sphenoidal disease. Nowadays, in our opinion, the paraseptal direct sphenoidotomy represents the less invasive, fastest and most anatomically conservative approach to the sphenoid sinus in case of SSFB

Abstract
BACKGROUND: Fungal rhinosinusitis is a common disease of the paranasal sinuses. The fungus ball (FB) is defined as an extramucosal mycotic proliferation that fills one or more paranasal sinuses. Sphenoid sinus is an uncommon localization of this disease, as reported in the literature. This study describes our experience in the diagnosis and treatment of sphenoid sinus FB (SSFB), with a particular focus on the surgical approach to the sphenoid sinus. METHODS: We retrospectively analyzed the clinical records of patients affected by FB of the sphenoid sinus, who underwent endoscopic sinus surgery (ESS) in our institutions between 1995 and 2009. We described the surgical technique, the methods of mycological and histopathological evaluation, as well as the perioperative and postoperative management. RESULTS: From 1995 to 2009, 226 patients affected by sinonasal FB underwent ESS in our institutions. A sphenoid localization was found in 56 patients (24.78%; mean age, 62 years).
