Dr. Suhas Udayakumaran, Onyia, C. U., and Cherkil, S., “An Analysis of Outcome of Endoscopic Fenestration of Cavum Septum Pellucidum Cyst - More Grey than Black and White?”, Pediatr Neurosurg, 2017.[Abstract]

BACKGROUND: Cavum septum pellucidum (CSP) and cavum vergae are actually fluid-filled, generally communicating midline cavities located between the third ventricle and corpus callosum. There have been various reports of their association with many behavioral and psychiatric disorders. Infrequently, they have been associated with an obstructive hydrocephalus-like picture. Although the structure and management of CSP has long been known, it has been an enigma as far as functional significance and management indications are concerned. The authors of this article try to analyze the significance of a persistent cavum and involvement of the same entity in varied presentations ranging from an incidental imaging finding to acute hydrocephalus, and propose a possible implication on the present surgical intervention paradigm.

PURPOSE: To assess the surgical outcome of fenestration of a CSP cyst.

METHODS: Retrospective analysis of 3 patients who underwent endoscopic fenestration for CSP with obstructive hydrocephalus between 2012 and 2014 was done, and data were analyzed for symptomatic clinical improvement in particular behavior.

RESULTS: Pre- and postoperative brain MRI showed a significant decrease in the size of the cyst as well as the ventricles. There were no recurrences during follow-up. All of the patients improved.

CONCLUSIONS: (1) Endoscopic fenestration of symptomatic CSP cysts is a safe treatment option. (2) Neurocognitive assessment is essential in the evaluation and outcome assessment of CSP.

Dr. Suhas Udayakumaran and Onyia, C. U., “Customizable rigid head fixation for infants: technical note.”, Childs Nerv Syst, vol. 32, no. 1, pp. 159-61, 2016.[Abstract]

<p><b>INTRODUCTION: </b>The need and advantages of rigid fixation of the head in cranial surgeries are well documented (Berryhill et al., Otolaryngol Head Neck Surg 121:269-273, 1999). Head fixation for neurosurgical procedures in infants and in early years has been a challenge and is fraught with risk. Despite the fact that pediatric pins are designed, rigid head fixation involving direct application of pins to the head of infants and slightly older children is still generally not safe (Agrawal and Steinbok, Childs Nerv Syst 22:1473-1474, 2006). Yet, there are some surgeries in which some form of rigid fixation is required (Agrawal and Steinbok, Childs Nerv Syst 22:1473-1474, 2006). We describe a simple technique to achieve rigid fixation of the head in infants for neurosurgical procedures.</p><p><b>TECHNICAL NOTE: </b>This involves applying a head band made of Plaster of Paris (POP) around the head and then applying the fixation pins of the fixation frame directly on to the POP.</p><p><b>CONCLUSION: </b>We have used this technique of head fixation successfully for infants with no complications.</p>
