Mapping the nose – first spatial map of olfaction published
Scientists at Harvard Medical School have created the first detailed map of smell receptors in the nose, catching up with similar achievements in sight, hearing and touch. The map reveals that smell receptors are highly organised into tight bands based on type. The findings provide foundational knowledge needed to develop better therapies for loss of smell.
Fingernail for orbital floor reconstruction
Orbital damage is common in maxillofacial injuries and about half of them result in damage to the orbital floor. Suitable material that could be used for repairing the orbital floor includes autografts, allografts and alloplastic materials. The disadvantage of using...Update on the development of an implantable vestibular prosthesis
Cochlear implants have revolutionised the management of profound hearing loss. Might vestibular implants be the future for the treatment of bilateral vestibular failure? James Johnston and Neil Donnelly explore. The vestibular system is highly complex, integrating visual, labyrinthine and proprioceptive...
Adult Audiology Casebook
This is quite an intriguing audiology text, which takes some time to get into. The first couple of cases are a bit obscure and off putting; however, by choosing individual cases to read, rather than reading through the book systematically,...
GORD and CRS – is there an association?
This international collaboration assessed 32 papers which had published original data on the experimental, diagnostic, treatment or prognostic association between GORD and CRS. The study aims to systematically review the evidence for a role of GORD in CRS. Case control,...
Role of sentinel lymph node biopsy in managing papillary thyroid cancer
Although studies have shown that the presence of lymph nodes metastases in papillary thyroid carcinoma does not alter survival, other studies have shown that it increases morbidity and mortality and that the presence of cervical lymph node metastasis at diagnosis...
When should we decompress the facial nerve in Bell’s Palsy?
It has been over three decades since Fisch popularised facial nerve (FN) decompression for Bell’s Palsy. Studies further exploring this have been few since, partly due to the major complications that can occur following this type of surgery. The current...
Hearing loss in the contralateral ear after mastoid drilling
It is difficult to conceive that most of the noise generated by drilling the mastoid would not be conveyed to the contralateral cochlea, by direct transmission through the skull bone, where the attenuation factor is only 5-10 dB. Only a...
DVT prophylaxis in cranial procedures
Deep vein thrombosis (DVT) is a result of disturbed balances in blood flow patterns, blood clotting factors promoting coagulation and vessel wall endothelial injury. The subsequent disruption of coagulation and fibrinolysis mechanisms lead to venous clot formation and propagation. The...
Sphenopalatine ganglion block in endoscopic sinus surgery reduces intra and post-operative morbidity
The authors present results of a meta-analysis to investigate the role of sphenopalatine ganglion block (SPGB) in reducing postoperative pain in endoscopic sinus surgery (ESS). An electronic database search (Pubmed, SCOPUS, Google Scholar, Embase, and the Cochrane Register of Controlled...
3D endoscopy in pituitary adenoma surgery
Endoscopic approach for pituitary adenoma surgery is well recognised. There has been recent refinement of 3D endoscopy technology which improves on the depth of vision offered and more compact delivery. This may improve visualisation of the critical structures involved in...
