External auditory exostosis (surfer’s ear) is a progressive condition of benign hyperostotic overgrowths of the external auditory canal, secondary to repetitive cold-water exposure, in which symptoms correlate to degree of exostosis. Surgical intervention is the only available treatment, most commonly using the osteotome or microdrill, but these carry a risk of sensorineural hearing loss, post-operative stenosis, temporomandibular dysfunction and tympanic membrane perforation.

We describe in detail the Swansea technique, an innovative method of canaloplasty with endoscopic underwater excision of exostoses using a piezoelectric saw and continuous irrigation with 1:1,000,000 adrenaline, with the results from our first 34 procedures.

The inherent properties of the piezoelectric saw reduce the risk of overall complications when compared with traditional methods, whilst the surgical set-up is cost-equivocal and easily implemented in departments with endoscopic capabilities.

The piezoelectric saw is a promising novel technique for the treatment of external auditory exostosis.

Nasal saline lavage forms a cornerstone of chronic rhinosinusitis management. A number of saline lavage recipes and products are currently available but little is known of their relative physical characteristics.

To determine the osmolarity and pH of nasal lavage solutions, both commercial preparations and home-made recipes, and to determine the reproducibility of saline solution preparation.

Five home-made recipes and two commercial products were prepared in triplicate and analysed. Eight consecutive clinic patients prepared a commercial product and 11 prepared a home-made recipe, and the osmolarity and pH were measured.

The osmolarity of the solutions varied widely, from 140 to 788 mmol/l and the pH varied from 7.88 to 8.50. The commercial and home-made solutions had similar reproducibility when prepared by patients.

Some recipes were markedly hypo-osmolar and some were hyper-osmolar. All were slightly alkaline. The home-made recipes had similar physical characteristics and reproducibility to commercial preparations.

Syringing of the ear is one of the most common procedures performed for cleaning cerumen from the external auditory canal. Common complications following syringing are pain, external auditory canal trauma and otitis externa. Hearing and vestibular loss have also been reported as complications. However, we are unaware of any report of facial nerve palsy as a complication of ear syringing. Such a case is reported.

We describe a case of facial nerve palsy as a complication of syringing, which demonstrates the dramatic presentation of this condition and emphasises the need for great care while syringing the ears.

It is important to be aware of this unusual complication with its distinctive presentation. Surgical intervention should be undertaken at the earliest opportunity, for favourable results. A risk-minimising strategy for ear syringing is recommended.
