Postinfectious olfactory disorders

Recovery of olfactory function following URTI is frequent, even many years after the infectious insult. Upper respiratory tract infection is the commonest cause of olfactory loss. Many treatment options exist including topical steroids, vitamin B, acupuncture, and zinc, which can...

Treatment algorithm for olfactory disorders

The purpose of this paper is to review the current evidence in diagnosing olfactory disorders and suggest an algorithmic approach to patients with relevant complaints. Age-associated olfactory loss is often multifactorial and requires a careful history and physical exam. A...

Treatment of olfactory dysfunction

The sense of smell is crucial to our being able to relish food and experience our environment. Olfactory dysfunction has been trivialised or ignored previously, but the negative consequences of the loss of sense of smell are being increasingly highlighted....

Olfactory neuronal damage in sinusitis

So many patients with nasal disorders have poor olfactory function, yet sometimes the nose may seem comparatively clear of conductive problems. This study postulated that neuronal damage in the olfactory apparatus would lead to a leakage of neuron specific enolase...

Olfactory function and vitamin D

This Turkish prospective study evaluated olfactory function in individuals with primary vitamin D deficiency and the effect of replacement therapy on olfactory function over an eight-month period in 2019. A total of 91 individuals with vitamin D insufficiency were included,...

Olfactory disorders in COVID-19

This Turkish prospective longitudinal observational study evaluated olfactory disorders (OD) and recovery processes in patients with COVID-19 infection at three time points within the first month of diagnosis: time of diagnosis with positive PCR test; time of first negative PCR...

Olfactory ensheathing cells and their safe harvest

This interesting and unique paper not only demonstrates that biopsy of olfactory mucosa in the region of the superior turbinate is a safe procedure but also provides valuable insight into an engaging area of research by a world class team...

Olfactory and gustatory recovery in coronavirus patients after six months

It remains unclear for how long olfactory and gustatory losses persevere in patients with COVID-19. This is a prospective study of 300 patients who lost taste and smell within seven days of contracting COVID-19. The patients were objectively assessed with...

Olfactory protective effect of omega-3 supplements during healing after endoscopic sellar and parasellar resection

This multicentre study, led by researchers from Stanford, demonstrates another use for omega-3 supplements. The study analysed cohorts equally divided between control arm and omega-3 supplementation. Post endoscopic sellar and parasellar resection, better olfactory function was observed at three and...

To scan or not to scan?

This comprehensive review article seeks to establish how useful is MRI in the evaluation of patients with a history of smell loss or distortion. Interestingly, while some studies found the imaging unhelpful, one paper described found a 25% rate of...

Earlier intervention to correct anosmia?

This is an interesting study aimed to determine the timing for successful surgical intervention in improving the sense of smell in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). A total of 86 CRSwNP patients with loss of smell and...

CRSwNP and smell – is it just the obstruction?

Anosmia and hyposmia are symptoms of CRS both with and without nasal polyps and can significantly affect quality of life. The nature of anosmia/hyposmia is thought to be both sensory-neural and conductive. These authors studied a mouse model in which...
