Endoscopic Solution to Rhinogenic Contact Headaches
Journal Title: Bengal Journal of Otolaryngology and Head Neck Surgery - Year 2016, Vol 24, Issue 2
Abstract
IntroductionHeadache is a common complaint that brings patients to multidisciplinary clinics. It is utmost important to have meticulous clinical diagnosis of patients with rhinogenic and non sinusogenic headaches. The diagnosis has become easier with the advent of modern endoscopy and endoscopic sinus surgical techniques. This study aims to investigate the role of some anatomical nasal abnormalities in rhinogenic contact headache and to evaluate response to endoscopic surgery. Materials and MethodA prospective study was conducted at a secondary level regional referral Hospital in the Sultanate of Oman. Patients with long-lasting, frequent, severe headaches not amenable to medical treatment, above 20 years of age were taken into consideration. Routine nasal endoscopy, Computerized tomography scan of the paranasal sinuses, Nasal decongestion and various surgical techniques to correct the anatomical abnormalities were included in our study and results were correlated statistically. ResultThere was a male predominance in our study with duration of headache ranging from 2 weeks to 5 years. There was a preponderance of headache in frontal region in our study group. Diagnostic nasal endoscopy and CT scan of PNS revealed Deviated nasal septum / septal spur, concha bullosa, Haller cell, pneumatised uncinate process and agar nasi cells. The overall success rate of the surgery in relieving headaches, measured by the MIDAS- VAS score, was approximately 75 %. The non-parametric Wilcoxon signed rank test, Chi square and paired T tests shows that the following study has rejected the null hypothesis as statistically significant where the P value <0.05. DiscussionResearchers have examined the contact points as a source of rhinogenic / contact headache. Intranasal mucosal contact released substance P, causing pain and headache, Substance P has a potent vasodilator effect. Vasodilatation and perivascular inflammation are the final common pathways in pain. Surgical treatment for contact point-induced headaches has had good success. ConclusionThe etiology of rhinogenic headache is multifactorial. Complete history taking, scrupulous preoperative evaluations, multidisciplinary consultations, Initial medical controls, long observation, and diligent postoperative follow-ups are mandatory for not only accurate diagnosis but also for promising surgical outcomes of non-sinusitis related rhinogenic headache. Our experience reveals that patients with rhinogenic contact headaches can benefit significantly from meticulous endoscopic decompression
