Endoscopic Repair of Spontaneous Cerebrospinal Fluid Leaks in the Lateral Recess of the Sphenoid Sinus

Objective This study aimed to assess the effectiveness of 3 endoscopic endonasal approaches for the management of cerebrospinal fluid (CSF) leaks and meningoencephaloceles in the lateral recess of the sphenoid sinus (LRSS). Study Design Retrospective study. Setting University hospital. Methods This study retrospectively reviewed 49 patients with CSF leaks and meningoencephaloceles in the LRSS. Three endoscopic surgical repair approaches were indicated based on 5 different Rhoton’s types of the LRSS. The postoperative symptoms, complications, and follow-up outcomes were investigated and evaluated. Results The success rate of endoscopic surgical repair was 100% at a median follow-up of 75.06 (12-203.4) months. Endoscopic approaches to the LRSS included the prelacrimal recess (PLR) (18.37%), transsphenoidal (18.37%), and transpterygoid approaches (64.26%). All patients in the PLR approach (PLRA) group and most of the patients in the transpterygoid approach group had a full lateral type LRSS. Hypoesthesia and dry eyes were reported in 5 patients (55.56%) and 1 (11.12%) patient, respectively, from the PLRA group and in 6 (19.35%) and 5 (16.12%) patients, respectively, from the transpterygoid approach group. Conclusions Endoscopic closure is a safe and effective method for the treatment of CSF leaks and meningoencephaloceles in the LRSS. The transpterygoid approach and PLRA offer adequate exposure of the LRSS with extensive lateral pneumatization or a full LRSS. The endoscopic route of the PLRA is more direct than that of the transpterygoid approach. Careful preoperative imaging evaluation is crucial while selecting the optimal surgical approach for the repair of a skull base defect.

A Case Report of Inflammatory Myofibroblastic Tumor of the Sphenoidal Sinus

Inflammatory myofibroblastic tumor (IMT) is a tumor composed of differentiated myofibroblastic spindle-shaped cells. It occurs in the soft tissues of the abdomen and lungs, and is very rare in the sphenoid sinus. The diagnosis depends on histopathology and immunohistochemistry, and is easily misdiagnosed. Although metastasis is rare, the recurrence rate is high. Surgical resection is the treatment of choice, and where complete resection is difficult, radiation therapy, hormonal therapy, or molecular targeted drug therapy can be administered. We report a rare case of IMT with a primary origin in the sphenoid sinus, which was entirely resected by nasal endoscopy and confirmed by histological examination.

Sphenoid sinus mucocele with unilateral blindness – a case report

Mucocele of the paranasal sinuses are benign cystic lesions filled with mucus. They occur in the sphenoid sinus in 1–2% of all paranasal sinuses, most often in the fourth decade of life. Clinical manifestations are non-specific, caused by pressure expansion into anatomical structures immediately adjacent to the sphenoid sinus. They are manifested by headaches, dropped eyelids, impaired movement of the globe, and impaired vision. In the differential dia­gnosis, it is necessary to distinguish them from tumour processes and processes propagating from the intracranium. Computed tomography (CT) and Magnetic Resonance Imaging (MRI) play an important role in the dia­gnosis, the definitive dia­gnosis is determined by perioperative findings and histological examination. Curative surgical options include endoscopic transnasal sphenoidotomy with marsupialization. In this article, we present a case of a patient with a mucocele of the sphenoid sinus, which was the cause of unilateral blindness.

Surgical Management of Acute Sphenoid Sinusitis: A Review

Sphenoidal sinusitis is usually described as acute inflammation of the sphenoid sinuses - either one or both - (the two large cavities just behind the nose and between the eyes). The disease is relatively uncommon—comparatively, chronic sphenoid sinusitis is more common—and may be limited to the sphenoid sinus or, more commonly, may involve multiple sinuses or pansinusitis. Acute sphenoid sinusitis can lead to symptoms such as headaches, nausea, and even complications in the orbit. For low vision, early diagnosis and treatment is essential to preserve vision and life. This study aims Learn about surgical approaches to the treatment of acute sinusitis

Extramedullary Plasmacytoma of the Sphenoid Sinus presenting with visual loss: a Case Report

A rare case of sphenoid plasmacytoma in a 57-year old female who was presented with a frozen eye is reported. It was histopathologically confirmed based on transsphenoidal biopsy. Surgical removal of the tumor with complementary radiotherapy was performed as a treatment modality
