“…Frequency of pneumatized uncinate process has been reported as 1.5–3%. 8,11,12 However, we identified this variant in 11% of subjects. It is difficult to comment on whether our results deviate from the norm, because there is little published data on the prevalence of middle ethmoidal artery or pneumatized uncinate process.…”

“…Although substantial data exists outlining the prevalence of variant sinus anatomy in various populations, 2,8–37 few studies have evaluated correlations between or among them. In a small study of 47 children with chronic sinusitis, Sivasli et al demonstrated weak associations between presence of agger nasi cells and pneumatization of superior turbinate (ST) and MT, presence of large ethmoid bulla and pneumatized ST and secondary MT, and presence of Haller (infraorbital ethmoid) cell and pneumatization of ST. 12…”

“…An association of sinonasal anatomy and headaches presumably triggered by Chinook winds has been described. 20 The authors concluded that anatomical variations blocking the sinus ostia may prevent equilibration of changes in atmospheric pressure, thus forming a risk factor for these headaches.…”

Background: Changes in atmospheric pressure are suggested to trigger headaches. This pilot study was made to determine craniofacial sensations accompanying short phases of changing barometric pressure. Methods: In a crossover design, 15 adult healthy subjects were exposed in a climate chamber to 8 min phases of barometric pressure lowering by 0, 20 and 40 hPa. The subjects rated their sensations of ear pressure, head compression and the occurrence of headache every minute on a visual analogue scale (VAS, range 0–10). Pulse rate was recorded as a parameter for autonomic functions. Results: Nearly all subjects experienced ear pressure and half of them compression of their head at variable degrees. These sensations started in most subjects during the phase of lowering barometric pressure and increased to an average rating of about 3 VAS when returning to ambient atmospheric pressure. Heart rate slightly decreased during this phase. Three subjects reported mild to moderate headache for various durations within these phases. Conclusions: Changes in barometric pressure can be associated with sensations of ear pressure and head compression and may trigger headaches. The generation of these sensations is discussed with regard to convergent trigeminal innervation of the ear, the paranasal sinuses and the cranial meninges.

“…The warm wind is theorized to result in an increased concentration of positive ions with rapid ambient pressure changes that can produce barosinusitis. Rudmik et al 7 indicated that several anatomic variants may predispose individuals to Chinook-wind–related barosinusitis. These include the presence of concha bullosa, sphenoethmoidal cells, and large maxillary sinus volumes, which all serve to increase the relative volume of the sinonasal cavity.…”

“…In 1965, Flottes 4 reported the first case of diving-related barosinusitis, which occurred in a deep sea diver who was using a self-contained underwater breathing apparatus. Over the past 50 years, additional causes of sinus barotrauma have also been documented and include the use of gaseous general anesthetic agents, 5 hyperbaric oxygen therapy, 6 Chinook wind exposure, 7 prolonged high altitude exposure, 8 automobile travel, 9 submarine decompression, 10 nasal blowing, 11 and vigorous Valsalva maneuver 12 ( Table 1 ).…”

Background:Barosinusitis, or sinus barotrauma, may arise from changes in ambient pressure that are not compensated by force equalization mechanisms within the paranasal sinuses. Barosinusitis is most commonly seen with barometric changes during flight or diving. Understanding and better classifying the pathophysiology, clinical presentation, and management of barosinusitis are essential to improve patient care.Objectives:To perform a comprehensive review of the available literature regarding sinus barotrauma.Methods:A comprehensive literature search that used the terms “barosinusitis,” “sinus barotrauma,” and “aerosinusitis” was conducted, and all identified titles were reviewed for relevance to the upper airway and paranasal sinuses. All case reports, series, and review articles that were identified from this search were included. Selected cases of sinus barotrauma from our institution were included to illustrate classic signs and symptoms.Results:Fifty-one articles were identified as specifically relevant to, or referencing, barosinusitis and were incorporated into this review. The majority of articles focused on barosinusitis in the context of a single specific etiology rather than independent of etiology. From analysis of all the publications combined with clinical experience, we proposed that barosinusitis seemed to fall within three distinct subtypes: (1) acute, isolated barosinusitis; (2) recurrent acute barosinusitis; and (3) chronic barosinusitis. We introduced this terminology and suggested independent treatment recommendations for each subtype.Conclusion:Barosinusitis is a common but potentially overlooked condition that is primed by shifts in the ambient pressure within the paranasal sinuses. The pathophysiology of barosinusitis has disparate causes, which likely contribute to its misdiagnosis and underdiagnosis. Available literature compelled our proposed modifications to existing classification schemes, which may allow for improved awareness and management strategies for barosinusitis.

Chinook Wind Barosinusitis: An Anatomic Evaluation

Abstract: Chinook winds are a common source of facial pain and pressure. This is the first study to show that sinonasal anatomic variations may be a predisposing factor. Anatomic variants may induce facial pain by blocking the natural sinus ostia, thus preventing adequate pressure equilibrium.
