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.

Petroclival lesions represent a surgical challenge during the endonasal endoscopic approach, as they may involve maneuvers with severe comorbidity. To avoid the morbidity caused by these maneuvers, a contralateral transmaxillary approach (CTA) has been proposed to complement the endoscopic endonasal approach. The aim of our study is to review the safety and efficacy of this approach.

Encephaloceles are considered rare with an approximate incidence of 1 in 35,000, and sphenoid encephaloceles are even more uncommon. Two types of sphenoid encephaloceles exist: medial perisellar encephaloceles, and lateral sphenoidal encephaloceles. Surgical correction of the lateral sphenoid recess encephalocele is achieved via one of two endoscopic approaches: extended sphenoidotomy or transpterygopalatine.

In this video, we demonstrate the technique of endoscopic transpterygoid trans lacerum trans cavernous approach for the excision of Knosp 4 functioning pituitary macroadenomas. We highlight the anatomy and key steps of the approach using cadaveric dissection and present two clinical cases. A 42-year-old female with a growth hormone-secreting tumor and Knosp 4 macroadenoma underwent an extended endoscopic endonasal approach and near-total excision of the tumor.

Accessing Meckel's cave for biopsies of indeterminate lesions presents significant surgical challenges. This systematic review evaluates various approaches, with a focus on minimally invasive endoscopic techniques. A review of 75 studies reveals that the endoscopic endonasal transpterygoid approach offers improved visualization, reduced morbidity, and favorable outcomes, as demonstrated by an illustrative case of diffuse large B-cell lymphoma.

We report a challenging and uncommon case involving a 53-year-old Japanese man with cerebrospinal fluid (CSF) leakage caused by a meningocele in the lateral recess of the sphenoid sinus. Our innovative treatment approach involved a combination of transpterygoid and endoscopic modified medial maxillectomy techniques, with special emphasis on the preservation of the sphenopalatine artery. This strategic preservation was pivotal to the successful use of the ipsilateral nasoseptal flap for reconstruction, which played a crucial role in the prevention of postoperative CSF leakage.
