The sphenoid sinus has often been referred to as the neglected sinus because of its isolated position and difficult accessibility. Disease restricted to the sphenoid sinus is rare and often manifests with nonspecific or subtle signs and symptoms. Typically, patients are referred to the otolaryngologist because of a finding of isolated sinus opacification on CT scans ordered by the patient’s primary care physician or neurologist to evaluate vague symptoms such as headache.
17
Classification Isolated sphenoid sinus disease can be broadly divided 1. Inflammatory 2. Neoplastic 3. Miscellaneous categories
18
Inflammatory lesions Sinusitis Acute Chronic Fungal infections Invasive: Mucormycoses, disseminated Aspergillosis Noninvasive: Mycetoma, Aspergilloma Mucoceles Pyoceles
19
Neoplastic lesions Benign Malignant Intrinsic: 1. Inverting papillomas 2. Myofibroma 3. Schwannoma 4. Osteochondroma 5. Fibro-osseous disorders (fibrous dysplasia, ossifying fibroma) Extrinsic: 1. Meningioma 2. Paraganglioma 3. Pituitary macroadenomas Primary: 1. Squamous cell carcinoma 2. Adenocarcinoma 3. Adenoid cystic carcinoma 4. Mucoepidermoid carcinoma 5. Undifferentiated carcinoma 6. Transitional cell carcinoma Metastatic: 1. Renal cell carcinoma 2. Thyroid carcinoma 3. Prostate adenocarcinoma 4. Breast carcinoma 5. Lung carcinoma 6. Melanoma 7. Multiple myeloma and lymphoma
20
Miscellaneous Cerebrospinal leaks 1. Traumatic 2. Spontaneous Encephaloceles
21
Clinical signs and symptoms The most common symptom of sphenoid sinus disease is headache Visual disturbance is the second most frequently reported symptom Nasal obstruction Smell and taste Cranial nerve palsies Dizziness
22
Evaluation CT Scan: Air-fluid level 1. Acute & Chronic sinusitis 2. Polyp 3. Aneurism Thining & Expansion 1. Mucocel 2. tumor Sclerosis 1. Fungal 2. Fibroossous Bone erosion 1. Malignant Tumor
23
Chordomas Relatively rare tumors deriving from rests of embryonal notochord tissue located in the skull base, spine, and sacrococcygeal regions. Skull base chordomas are typically located in the midline, in the clival and basisphenoid regions
24
Symptoms Slow-growing tumors; therefore, most patients will relate a fairly long history of symptoms on initial presentation. Symptoms in a given patient will depend on the exact location of the tumor. Most commonly, the patient will report headaches and visual changes Diplopia secondary to cranial nerve (CN)VI paresis, Facial numbness, facial droop, Dysphagia, Hoarseness CN XII paresis
25
Evaluation CT Scan Reveal destruction of bone in a lytic pattern MRI T1: Isointense or hypointense lesion T2: bright signal that may appear heterogeneous. Gd: Enhancement is typically moderate to high
26
Management Current and historical management of skull base chordomas has involved : 1. Surgical excision 2. Radiation therapy 3. Both
