هدف هذا البحث لدراسة حالات الإصابة المعزولة بالجيب الوتدي من حيث الأعراض، و أسباب الإصابة، و طريقة تدبيرها، و فعالية هذه الطريقة. إن آفات الجيب الوتدي المعزولة هي آفات غير شائعة؛ إلا أنها قد تدل على آفات خطيرة و قد تكون السبب لاختلاطات عصبية و عينية مهمة.
To evaluate the symptoms, causes, methods of management and efficacy of this methods of isolated sphenoid sinus disease. Isolated sphenoid sinus disease is uncommon, but it may be critical and a cause of important ocular and neurological complications.

From literature review concerning diagnosis and management of isolated sphenoid fungal sinusitis we found that this isolated lesion is extremely rare especially in immunocompetent patients; it is frequently difficult to diagnose, as patients present
with nonspecific symptoms such as headach, visual disturbance and cranial nerve palsies. Diagnosis of the disease is typically not made until advanced imaging has been developed. We presented a case of isolated fungal sinusitis of left sphenoid sinus with headach and diplopia, treated by endoscopic sphenoidotomy with the help of the navigation system, after which recovery was full.
We conducted a randomized clinical trial on 32 subjects in 2 groups with chronic
diseases of the sphenoid sinus (each consisting of 16 patients) to evaluate CT navigation
during Functional Endoscopic Sinus Surgery. All patients registered in our st
udy met the
widely accepted criteria to be treated with FESS. 16 patients were operated on with FESS
with CT navigation while 16 patients were operated on with FESS without navigation. The
result drawn showed no significant statistical difference in the outcome of the operations
when we used the CT navigation during FESS compared with the time we did not use it.
However, we believe it is an asset to the ENT surgeon in difficult and critical operations
like the sphenoid sinus surgery as it brings precision and peace to the surgeon. We
recommend using CT navigation as a useful adjunct added to the surgeon’s knowledge &
experience but not as a replacement to these necessities.

Presence of maxillary septa has been known to be a complicating factor for sinus elevation procedure.
This study was aimed at detecting the prevalence, location and height of antral septa in syrianpopulation and to determine whether there is a relat
ionship between the presence of septa and the absence of upper molars .
A total of 174 sinuses in 87 patients (59 male and 28 female) aged 27 - 51 years were evaluated through a computed tomography scan analysis .
No correlation was observed between the presence of septa and the absence of upper molars.
Graft insertion can effectively enhance the regeneration of
debilitated bone.
Aim: The effects of an alloplastic bone-replacing material, b-tricalcium
phosphate, and of autogenous bone graft were compared.
