BACKGROUND: Epistaxis is a frequent problem otorhinolaryngologists faces of in their practice. The variations of the sphenopalatine foramen and consequently the artery may be one of the major sources of such bleeding. AIM OF THE WORK: The present work aimed at to localize the site of sphenopalatine foramen and also to illustrate its different shapes, number and any other variation. MATERIALS AND METHODS: In the current study, twenty adult skulls of both sexes with total 40 half skulls were used in addition to 20 heads of adult living subjects of both sexes aged between 30-60 years examined with multislice helical CT with 3-D reconstruction of SPF...

A 64 year-old man with pituitary adenoma developed massive epistaxis after an uneventful endoscopic transsphenoidal surgery. Angiography showed extravasation from the sphenopalatine artery, to which embolisation was performed. An incidentally coexisting ethmoidal dural arteriovenous fistula supplied by the ophthalmic artery aberrantly originated from the middle meningeal artery caused increased haemorrhage.

Pedicle flaps based on the external maxillary (facial) artery were introduced during the World War I, precisely a century ago. Today they remain effective tools in facial soft-tissue repair. Recently, pedicle flaps based on the internal maxillary (sphenopalatine) artery have been chosen to reliably close dural defects after endoscopic skull-base surgery. Pedicle flaps, "biologic" to the extent they are based on a defined arterial blood supply, are the lasting contributions-the diuturnity-of Johannes ("Jan") Fredericus Samuel Esser (1877-1946) of Leiden, Holland, and Chicago (IL)...

INTRODUCTION: Cluster headache is characterized by attacks of severe unilateral pain accompanied by cranial and systemic autonomic changes. Our knowledge of the latter is imperfect. This study aimed to investigate the effect of low-frequency sphenopalatine ganglion stimulation on cardiac autonomic regulation. MATERIALS AND METHODS: In a double-blind, randomized, sham-controlled crossover design, patients received low-frequency and sham stimulation. RR intervals were recorded, and heart rate variability was analysed (time-domain, frequency-domain, nonlinear parameters)...

Background Low frequency (LF) stimulation of the sphenopalatine ganglion (SPG) may increase parasympathetic outflow and provoke cluster headache (CH) attacks in CH patients implanted with an SPG neurostimulator. Methods In a double-blind randomized sham-controlled crossover study, 20 CH patients received LF or sham stimulation for 30 min on two separate days. We recorded headache characteristics, cephalic autonomic symptoms (CAS), plasma levels of parasympathetic markers such as pituitary adenylate cyclase-activating polypeptide-38 (PACAP38) and vasoactive intestinal peptide (VIP), and mechanical detection and pain thresholds as a marker of sensory modulation...

Background Recently it has been suggested that low frequency stimulation of the sphenopalatine ganglion (SPG) may provoke cluster-like attacks in cluster headache (CH) patients. The question arises whether a robust activation of cranial autonomic symptoms is sufficient to trigger CH attacks. Methods Kinetic oscillation stimulation (KOS) of the nasal mucosa generates ipsilateral marked autonomic symptoms, among which lacrimation is quantitatively measurable. KOS was applied to 29 CH-patients, including both episodic and chronic course...

BACKGROUND: Sympathetic fibers connect sphenopalatine ganglion (SPG) with the central nervous system. We aimed to study the effect of SPG block in blood pressure (BP) in never treated patients with stage I-II essential hypertension. METHODS: We performed bilateral SPG block with lidocaine 2% in 33 hypertensive patients (mean age 48±12years, 24 men) and a sham operation with water for injection in 11 patients who served as the control group (mean age 51±12years, 8 men)...

Basosquamous carcinoma is a rare, highly aggressive variant of basal cell carcinoma with elevated rates of recurrence, perineural invasion, and metastasis. We describe a patient who presented with unilateral complete ophthalmoplegia, ptosis, optic neuropathy, and trigeminal neuropathy due to perineural intracranial invasion of nasal basosquamous carcinoma via the sphenopalatine fossa to the cavernous sinus, orbit, and infratemporal fossa. To our knowledge, this is the first reported case of basosquamous carcinoma with perineural invasion involving the cavernous sinus in the English language ophthalmic literature...

PREMISE: Trigeminal neuralgia is a severe facial pain disorder that has been studied for decades. Classical trigeminal neuralgia (CTN) is either idiopathic or caused by neurovascular compression. The related painful trigeminal neuropathies are often secondary to other causes, such as multiple sclerosis or trauma. PROBLEM: Therapies for trigeminal neuralgia and neuropathy have often been pharmacologic or surgical. Pharmacologic therapies are not effective in some cases and often cause side effects, some substantial...

Hida Nierenburg, Morgane Swift Morris
PURPOSE OF REVIEW: External nasal neuralgia is a rare syndrome of atypical facial pain for which there is limited reports in the scientific literature. We aim to review diagnosis and provide an update on treatments for this rare condition. RECENT FINDINGS: Etiology has been documented as post-traumatic due to direct trauma to the nose area and in few case reports, idiopathic. Sensory innervation of the nose arises from the ophthalmic and maxillary divisions of the trigeminal nerve...

30% of the patients presenting with epistaxis at emergency wards and otorhinolaryngeal specialist departments have posterior bleeding. Traditional treatment with packing often leads to initial treatment failure, and many patients experience recurrent bleeding within the following month. Recurrent posterior epistaxis should be treated with local electrocautery or endoscopic ligation of the sphenopalatine artery to reduce patient discomfort, hospital stay, risk of treatment failure and recurrence.

With the development of endoscopic technique, Caldwell-Luc approach has more wide applications and becomes a common method of pterygopalatine fossa (PPF) surgery. Few data can be used in this approach to avoid injuring the vessels and nerves within this area. In this study, the authors used computed tomography to get the coordinates of inferior orbital fissure, foramen rotundum, sphenopalatine foramen, internal opening of pterygoid canal, the strangulation of PPF, and the greater palatine foramen with canine fossa as the origin...

OBJECTIVE: A modern imaging review is necessary to further define the anatomic origin of the juvenile nasopharyngeal angiofibroma. METHODS: After institutional review board approval, a search from January 1998 to January 2013 yielded 33 male patients (aged 10-23 years) with pathologically proven juvenile nasopharyngeal angiofibroma lesions, as well as pretreatment computed tomography/magnetic resonance imaging. Juvenile nasopharyngeal angiofibroma involvement was assessed in the following regions: sphenopalatine foramen, pterygopalatine fossa, vidian canal, nasopharynx, nasal cavity, sphenoid sinus, choana, pterygomaxillary fissure/masticator space, orbit, and sphenoid bone...

BACKGROUND: Transnasal endoscopic sphenopalatine artery ligation is becoming the procedure of choice for surgical management of intractable posterior epistaxis. Landmarks for localization of the sphenopalatine foramen can assist in rapid surgical exposure of the sphenopalatine artery. OBJECTIVE: This study examined distances from easily identified endoscopic surgical landmarks to the sphenopalatine foramen. METHODS: By using computed tomography of the sinus to study radiologic anatomy in 50 adults, distances were measured between five simple endoscopic landmarks and the sphenopalatine foramen...

The extracranial-intracranial (EC-IC) bypass using the maxillary artery (MA) has been successfully completed using a radial artery graft but the complicated anatomy and narrow exposure make it difficult. The purpose of this article is to define the microsurgical exposure of the MA through the middle fossa and describe the branches, diameter, and length of the MA available for the EC-IC bypass in the sphenopalatine fossa and anterior part of the infratemporal fossa. 5 cadaveric specimens were dissected bilaterally (10 MA dissections) to define the microsurgical anatomy of the MA through an intracranial approach...
