Nasal bleeding is a major complication that can occur during and after transsphenoidal surgery (TSS) for intra- and suprasellar tumors. In most cases, the cause of this bleeding can be attributed to a branch of the maxillary artery called the sphenopalatine artery, injury to which can lead to life-threatening situations. Upon exposure of the suprasellar region and planum sphenoidale during surg...

OBJECTIVES To systematically review the current literature on treatment of third and fourth branchial pouch sinuses with endoscopic cauterization, including chemocauterization and electrocauterization, in comparison to surgical treatment. DATA SOURCES PubMed, Embase, and the Cochrane Library. REVIEW METHODS We conducted a systematic search. Studies reporting original study data were include...

OBJECTIVE The optimal surgical treatment for patients with posterior epistaxis and failed conservative therapy is unknown. Therefore we planned a systematic review studying all available publications assessing the effect on bleeding recurrence and postoperative complications of ligation of the internal maxillary artery or the sphenopalatine artery. METHODS We searched the electronic databases...

Using immunohistochemistry, we studied the origins and pathways of parasympathetic and sensory nerve fibers to the pial arteries in four squirrel monkeys. Following its application to the surface of the middle cerebral artery, the retrograde axonal tracer True Blue accumulated in parasympathetic neurons of the sphenopalatine ganglion and the internal carotid ganglion. The latter is strategicall...

Fourth branchial complex anomalies are rare and typically present in neonates or adolescents. Surgical management via open excision is the traditional approach to prevent recurrence. However, endoscopic sinus cauterization has recently been reported as a less invasive alternative. The current case report represents the first published account of a fourth branchial pouch presenting in an adult p...

The posterior nasal nerves emerge from the sphenopalatine foramen and contain sensory and autonomic nerve components. Posterior nasal neurectomy is an effective method to remove pathological neural networks surrounding the inferior turbinate that cause unregulated nasal hypersensitivity with excess secretion in patients with severe allergic rhinitis (AR). We describe the sophisticated endoscopi...
