“…Providing luxury perfusion (blood flow in excess of local metabolic requirements) should alleviate symptoms associated with impaired CBF. Improvement in anosmia after SGB has been reported previously, although the mechanism is unknown ( Moon et al, 2007 ; Park et al, 2013 ; Moon et al, 2013 ). The immediate improvements in taste and smell reported by our patients may be due to increased CBF to brain structures responsible for these senses, or increased perfusion of the facial areas where the peripheral receptors for these senses reside.…”

After recovering from COVID-19, a significant proportion of symptomatic and asymptomatic individuals develop Long COVID. Fatigue, orthostatic intolerance, brain fog, anosmia, and ageusia/dysgeusia in Long COVID resemble “sickness behavior,” the autonomic nervous system response to pro-inflammatory cytokines ( Dantzer et al., 2008 ). Aberrant network adaptation to sympathetic/parasympathetic imbalance is expected to produce long-standing dysautonomia. Cervical sympathetic chain activity can be blocked with local anesthetic, allowing the regional autonomic nervous system to “reboot.” In this case series, we successfully treated two Long COVID patients using stellate ganglion block, implicating dysautonomia in the pathophysiology of Long COVID and suggesting a novel treatment.

“…Olfactory‐specific quality of life was measured using the following self‐report questionnaires in Korean: olfactory activity scale (OAS) and olfactory quality of life scale (OQS) that implement Likert rating scales (Choi et al, 2008; Park et al, 2013). The OAS consists of 14 statements evaluating whether participants can smell 14 categorized odors that are frequently encountered in Korean culture.…”

Loss of olfaction, or anosmia, frequently accompanies emotional dysfunctions, partly due to the overlapping brain regions between the olfactory and emotional processing centers. Here, we investigated whether anosmia was associated with gray matter volume alterations at a network level, and whether these alterations were related to the olfactory-specific quality of life (QOL) and depressive symptoms. Structural brain magnetic resonance imaging was acquired in 22 individuals with postinfectious or idiopathic anosmia (the anosmia group) and 30 age-and sex-matched controls (the control group). Using independent component analysis on the gray matter volumes, we identified 10 morphometric networks. The gray matter volumes of these networks were compared between the two groups. Olfactory-specific QOL and depressive symptoms were assessed by self-report questionnaires and clinician-administered interviews, respectively. The anosmia group showed lower gray matter volumes in the hippocampus-amygdala and the precuneus networks, relative to the control group.Lower gray matter volumes in the hippocampus-amygdala network were also linearly associated with lower olfactory-specific QOL and higher depressive symptom scores.These findings suggest a close relationship between anosmia and gray matter volume alterations in the emotional brain networks, albeit without determined causal relations.

IntroductionStellate ganglion block (SGB) provides diagnostic and therapeutic benefits in pain syndromes in the head, neck, and upper extremity, including complex regional pain syndrome Types I and II, Raynaud's disease, hyperhidrosis, arterial embolism in the region of the arm.MethodsWe present a novel ultrasound‐guided supraclavicular stellate ganglion block. Considering the existing anatomical structures of the targeted area.Results and ConclusionsWe hope that we can provide fewer complications and additional benefits with this new approach.
