Detailed Description

Fungal rhinosinusitis classified into invasive and noninvasive subtypes. Phenotypes of noninvasive fungal rhinosinusitis occur in immunocompetent subjects and include: local fungal colonization, fungal ball, and allergic fungal rhinosinusitis. Subtypes of invasive fungal rhinosinusitis include acute invasive fungal rhinosinusitis, chronic invasive fungal rhinosinusitis and granulomatous invasive rhinosinusitis.

The estimated incidence of sphenoid sinusitis is only 2.7% of all nasal sinus infections, also the diagnosis of sphenoid sinus fungal infection is sometimes difficult. Clinical signs are often non specific and nasal endoscopy can be strictly normal.Early diagnosis is therefore difficult and diagnosis is often delayed with headache that may sometimes persists for several years before diagnosis of the disease.

In most cases of sphenoid sinusitis, enlargement of the obstructed sinus ostium is sufficient to provide drainage of retained secretions and reestablish mucociliary clearance.According to Simmen and Jones, a type I sphenoidotomy entails identification of the ostium without further intervention; a type II sphenoidotomy entails enlargement of the ostium upward to the level of the cranial base, and inferiorly to one-half of the sinus height; and a type III sphenoidotomy involves widening the ostium to its most lateral extent.

Eloy et al in 2017 stuited that,In more extensive sphenoid sinus surgery is reserved for cases where in the disease process is extensive or previous surgery has failed. In some cases sphenoid nasalization in which bilateral extended sphenoidotomy is necessary. In this procedure, the posterior aspect of the nasal septum is resected, along with the sphenoid rostrum, the intersinus septum, and other intrasphenoid partitions, creating a common cavity with a broad drainage pathway . It also allows access to the lateral recesses of this sinus.

Interventions

  • Procedure: sphenoidotomy versus sphenoid nasalisation
    • sphenoidotomy opening of sphenoid sinus ostum and cleaning of the sinus sphenoid nasalization in which bilateral extended sphenoidotomy, the posterior aspect of the nasal septum is resected, along with the sphenoid rostrum, the intersinus septum, and other intrasphenoid partitions, creating a common cavity with a broad drainage pathway .

Arms, Groups and Cohorts

  • Active Comparator: sphenoidotomy (group A)
    • sphenoidotomy opening of sphenoid sinus ostum and cleaning of the sinus
  • Active Comparator: sphenoid nasalization (group B)
    • sphenoid nasalization in which bilateral extended sphenoidotomy, the posterior aspect of the nasal septum is resected, along with the sphenoid rostrum, the intersinus septum, and other intrasphenoid partitions, creating a common cavity with a broad drainage pathway .

Clinical Trial Outcome Measures

Primary Measures

  • rate of recurrence
    • Time Frame: 6 month
    • To assess the effect of nasalization of sphenoid sinus on recurrence rate of allergic fungal sinusitis Recurrence will be evaluated by clinical endoscopic evaluationof regular endoscopic examination first visit after one week,the second after 3 weeks and after 3month. CT nose and paranasal sinus will be done after 3 and 6 months.

Secondary Measures

  • Type of caustive organism
    • Time Frame: 2weeks
    • microbiological evaluation of the fungal mud will taken for culture to determine the type of the causative organism and determine if the fungal sinusitis is of invasive or non invasive type
