Introduction to the clinical stations
Published in Sukhpreet Singh Dubb, Core Surgical Training Interviews, 2020
Epistaxis is often precipitated by reduced humidity and colder climates, which cause loss of moisture in the nasal mucosal layer leading to cracks and breaches. Oxygenation via the nasal cannulae similarly can cause drying of the nasal mucosa. Preceding nasal trauma, including over-zealous nose blowing, can also cause damage and subsequent bleeding. Finally, medical conditions such as coagulopathy, hereditary haemorrhagic telangiectasia and angiofibromas are also causative factors.

It is critical prior to extubation and in the immediate post-operative period to have a clear discussion with the anaesthesia team. This potentially will avoid aggressive post-extubation mask ventilation, which can result in orbital subcutaneous emphysema. Expect large amounts of post-operative swelling, oedema, and erythema. Our patients are typically observed overnight and discharged on broad-spectrum antibiotics and instructed to start nasal irrigations. Patients should avoid nose blowing for 2 weeks to prevent subcutaneous emphysema or even prolapse of the globe.

The causes of epistaxis are listed in Table46.2. The most common site of bleeding is from Kiesselbach’s plexus in Little’s area of the anterior portion of the septum (see Figure46.36). Anterior bleeding is common in children and young adults as a result of nose blowing or picking. In the elderly, anticoagulants and hypertension are the underlying causes of arterial bleeding from the posterior part of the nose.
Development of a novel centrifugal extraction device to collect the olfactory cleft mucus

Several techniques have been developed for the collection of nasal secretions including nose blowing, vacuum collection, absorption, and nasal lavage [5]. To collect the surface fluid within the nasal cavity, a collector with absorptive properties, such as a piece of sponge, cotton wool, foam rubber, filter paper, and absorbent fibrous matrix, was inserted into the nasal cavity [6]. If a specific anatomic region of interest is to be sampled, such as olfactory cleft, endoscopic guidance should be used to minimize contact with vibrissae or other nasal surfaces [7]. Devices, such as cuvettes and Corning Costar Spin-X centrifuge tube filters have been utilized to extract the nasal secretions from the sponge, cotton wool, and foam rubber and different techniques resulted in various values of biomarkers [4,8]. A set of olfactory cleft mucus collection device and procedure has not been well established. It has been generally accepted that the methods of nasal secretion collection significantly influenced the results and there is an urgent need to build a standardized nasal secretion collection device and procedure.
Nose blowing-induced biphasic nystagmus of unknown origin

Nose blowing increases the middle ear and CSF pressure and can cause a perilymphatic fistula via the implosive and explosive routes [14]. If the same amount of pressure is applied to the inner ear simultaneously via the explosive and implosive routes, the pressures should cancel out and no collapse of the round and oval windows should occur. A perilymphatic fistula is likely to develop when the pressure changes from one of the routes predominates. The same should also be true for nose blowing, that is, if a similar amount of pressure is simultaneously applied to the inner ear via the explosive and implosive routes, the pressure should cancel out and have no effect on the inner ear. Vertigo and nystagmus caused by nose blowing would, therefore, occur when the pressure change from one of the routes predominates.
Orbital emphysema after transcanalicular laser-assisted dacryocystorhinostomy treated with needle decompression

This is a case of an 82-year-old man who had undergone transcanalicular diode laser-assisted dacryocystorhinostomy of both eyes due to chronic obstruction of the lacrimal duct. The day after the surgery, he complained of painful swelling in the left eye and blurry vision. The symptoms began to appear a few hours earlier after nose blowing. He presented a history of cataract surgery in both eyes and right eye amaurosis caused by optic atrophy secondary to an advanced glaucoma. No history of orbital or face trauma was reported.
