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...

Cluster headache is characterized by severe, unilateral headache attacks of orbital, supraorbital or temporal pain lasting 15-180 min accompanied by ipsilateral lacrimation, rhinorrhea and other cranial autonomic manifestations. Cluster headache attacks need fast-acting abortive agents because the pain peaks very quickly; sumatriptan injection is the gold standard acute treatment. First-line preventative drugs include verapamil and carbolithium. Other drugs demonstrated effective in open trials include topiramate, valproic acid, gabapentin and others...

PURPOSE: Epistaxis constitutes a significant proportion of the Otolaryngologist's emergency workload. Optimal management differs in relation to the anatomic origin of the bleeding. The outcome of our study was to determine which artery(ies) could be considered as the cause of severe bleeding in the context of severe epistaxis. METHODS: Fifty-five procedures of embolization preceded by angiography were reviewed. Medical records of interventionally treated patients were analysed for demographics, medical history, risk factors and clinical data...

PURPOSE OF REVIEW: Sphenopalatine ganglion (SPG) block has been used by clinicians in the treatment of a variety of headache disorders, facial pain syndromes, and other facial neuralgias. The sensory and autonomic fibers that travel through the SPG provided the scientific rationale for symptoms associated with these head and neck syndromes. Yet, despite the elucidation of this pathogenic target, the optimal method to block its pain-producing properties has not been determined. Clinicians have developed various invasive and non-invasive techniques, each of which has shown variable rates of success...

REVIEW
Abhijit S Nair, Basanth Kumar Rayani
The sphenopalatine ganglion (SPG) is a parasympathetic ganglion, located in the pterygopalatine fossa. The SPG block has been used for a long time for treating headaches of varying etiologies. For anesthesiologists, treating postdural puncture headaches (PDPH) has always been challenging. The epidural block patch (EBP) was the only option until researchers explored the role of the SPG block as a relatively simple and effective way to treat PDPH. Also, since the existing evidence proving the efficacy of the SPG block in PDPH is scarce, the block cannot be offered to all patients...

BACKGROUND AND OBJECTIVES: Postdural puncture headache (PDPH) is a common complication following subarachnoid blockade and its incidence varies with the size of the needle used and the needle design. Supportive therapy is the usual initial approach. Epidural blood patch (EBP) is the gold-standard when supportive therapy fails but has significant risks associated. Sphenopalatine ganglion block (SPGB) may be a safer alternative. CASE REPORT: We observed a 41 year-old female patient presenting with PDPH after a subarachnoid blockade a week before...

PURPOSE OF REVIEW: Chronic headache sufferers are estimated to be around 3% of the population. These patients have a high disease burden. When prophylactic treatments have low efficacy and tolerability, patients are in need of alternative therapeutic strategies and options. RECENT FINDINGS: In the last decade, a number of neuromodulation procedures have been introduced as treatment of chronic intractable headache patients when pharmacological treatments fail or are not well tolerated...

PURPOSE OF REVIEW: There is growing interest in neuromodulation for primary headache conditions. Invasive modalities such as occipital nerve stimulation, deep brain stimulation and sphenopalatine ganglion stimulation are reserved for the most severe and intractable patients. Non-invasive options such as vagal nerve stimulation (nVNS), supraorbital nerve stimulation (nSONS) and transcranial magnetic nerve stimulation (TMS) have all emerged as potentially useful headache treatments. This review examines the evidence base for non-invasive neuromodulation in trigeminal autonomic cephalalgias and migraine...

Vascular tumors of the nasal cavity can represent a variety of pathologies. In this case report, we discuss two patients presenting with a large vascular lesion occupying the nasal cavity. Significant bleeding was encountered during the initial attempts for endoscopic surgical resection. One lesion was successfully excised following preoperative embolization while a second following sphenopalatine artery vascular ligation. In both cases, final pathology showed lobular capillary hemangioma (LCH). We present a literature review and discussion of LCH and other vascular tumors that present in the nasal cavity...

REVIEW

BACKGROUND: Endoscopic sphenopalatine artery ligation is widely accepted as effective and safe for acute spontaneous epistaxis that is unresponsive to conservative management. As with many new procedures, it has been progressively adopted as common practice, despite a limited evidence base for its efficacy. Early reviews called for comparative trials to support its adoption, but subsequent literature largely consists of case series and narrative reviews. These have attempted to derive an algorithm to establish its place in management, but consensus is still lacking...

REVIEW
Miguel Ja Láinez, Edelmira Guillamón
BACKGROUND: The trigeminal autonomic cephalalgias (TACs) are highly disabling primary headache disorders. There are several issues that remain unresolved in the understanding of the pathophysiology of the TACs, although activation of the trigeminal-autonomic reflex and ipsilateral hypothalamic activation both play a central role. The discovery of the central role of the hypothalamus led to its use as a therapeutic target. After the good results obtained with hypothalamic stimulation, other peripheral neuromodulation targets were tried in the management of refractory cluster headache (CH) and other TACs...
