Muscle Graft

OBJECTIVEInjury to the internal carotid artery (ICA) is the most critical complication of endoscopic endonasal skull base surgery. Packing with a crushed muscle graft at the injury site has been an effective management technique to control bleeding without ICA sacrifice. Obtaining the muscle graft has typically required access to another surgical site, however. To address this concern, the authors investigated the application of an endonasally harvested longus capitis muscle patch for the management of ICA injury.METHODSOne colored silicone-injected anatomical specimen was dissected to replicate the surgical access to the nasopharynx and the stepwise dissection of the longus capitis muscle in the nasopharynx. Two representative cases were selected to illustrate the application of the longus capitis muscle patch and the relevance of clinical considerations.RESULTSA suitable muscle graft from the longus capitis muscle could be easily and quickly harvested during endoscopic endonasal skull base surgery. In the illustrative cases, the longus capitis muscle patch was successfully used for secondary prevention of pseudoaneurysm formation following primary bleeding control on the site of ICA injury.CONCLUSIONSNasopharyngeal harvest of a longus capitis muscle graft is a safe and practical method to manage ICA injury during endoscopic endonasal surgery.

Skull Base Defects

Abstract INTRODUCTION The most frequent complication of endoscopic endonasal surgery (EES) is postoperative cerebrospinal fluid (CSF) leak. This study was designed to develop a step-wise algorithm for EES reconstruction across the spectrum of skull base defects: from free mucosal graft for uncomplicated pituitary adenomas to free flaps in complex cases with recurrent leaks. METHODS All patients with skull base pathologies who underwent EES between January 2017 and December 2018 were included and retrospectively analyzed. Tumor location, reconstruction method and postoperative CSF leak were reviewed and a step-wise algorithm based on size and location of defect was developed. RESULTS Location of skull base defects was categorized as follows: anterior fossa, suprasellar, sellar and posterior fossa. For all nonsellar sites, we performed a multilayer (collagen matrix + /- fascia lata + /− fat graft + vascularized flap) reconstruction. The nasoseptal flap (NSF) was the first choice for vascularized reconstruction when available. For all sellar lesions we employed a free mucosal graft unless a high-flow CSF leak was present, in which case a single-layer reconstruction with NSF was performed. When the NSF was not available, alternative local (lateral nasal wall flap) and regional (extracranial pericranial flap) pedicled flaps were successful choices. When patients failed multiple attempts at repair, regional or microvascular free flaps were options. Lumbar spinal drainage was employed for large anterior and posterior fossa defects and during secondary repair of postoperative CSF leaks. Of 347 patients, 4.6% had a postoperative CSF leak. Of 158 patients with an intraoperative leak (45.5%), 10.1% developed a postoperative CSF leak: 7.8% for sellar/suprasellar defects and 13% for anterior/posterior fossa defects. CONCLUSION This algorithm provides a standardized, stepwise approach to the reconstruction of all skull base defects after EES based on location.

The Mean

Object The use of endoscopic endonasal surgery (EES) for skull base pathologies in the pediatric population presents unique challenges and has not been well described. The authors reviewed their experience with endoscopic endonasal approaches in pediatric skull base surgery to assess surgical outcomes and complications in the context of presenting patient demographics and pathologies. Methods A retrospective review of 133 pediatric patients who underwent EES at our institution from July 1999 to May 2011 was performed. Results A total of 171 EESs were performed for skull base tumors in 112 patients and bony lesions in 21. Eighty-five patients (63.9%) were male, and the mean age at the time of surgery was 12.7 years (range 2.3–18.0 years). Skull base tumors included angiofibromas (n = 24), craniopharyngiomas (n = 16), Rathke cleft cysts (n = 12), pituitary adenomas (n = 11), chordomas/chondrosarcomas (n = 10), dermoid/epidermoid tumors (n = 9), and 30 other pathologies. In total, 19 tumors were malignant (17.0%). Among patients with follow-up data, gross-total resection was achieved in 16 cases of angiofibromas (76.2%), 9 of craniopharyngiomas (56.2%), 8 of Rathke cleft cysts (72.7%), 7 of pituitary adenomas (70%), 5 of chordomas/chondrosarcomas (50%), 6 of dermoid/epidermoid tumors (85.7%), and 9 cases of other pathologies (31%). Fourteen patients received adjuvant radiotherapy, and 5 received chemotherapy. Sixteen patients (15.4%) showed tumor recurrence and underwent reoperation. Bony abnormalities included skull base defects (n = 12), basilar invagination (n = 4), optic nerve compression (n = 3) and trauma (n = 2); preexisting neurological dysfunction resolved in 12 patients (57.1%), improved in 7 (33.3%), and remained unchanged in 2 (9.5%). Overall, complications included CSF leak in 14 cases (10.5%), meningitis in 5 (3.8%), transient diabetes insipidus in 8 patients (6.0%), and permanent diabetes insipidus in 12 (9.0%). Five patients (3.8%) had transient and 3 (2.3%) had permanent cranial nerve palsies. The mean follow-up time was 22.7 months (range 1–122 months); 5 patients were lost to follow-up. Conclusions Endoscopic endonasal surgery has proved to be a safe and feasible approach for the management of a variety of pediatric skull base pathologies. When appropriately indicated, EES may achieve optimal outcomes in the pediatric population.
