Recent studies found that mobile phone users had a significantly greater risk of having elevated thresholds in speech frequencies. This study investigated the correlation between the laterality of sudden sensorineural hearing loss, handedness and the preferred ear for mobile phone use.

The study included all patients who presented with sudden sensorineural hearing loss to the Department of Otolaryngology – Head and Neck Surgery in our tertiary referral medical centre between 2014 and 2016. Patients were asked to indicate their dominant hand and preferred ear for mobile phone use.

The study comprised 160 patients. No correlation was found between the dominant hand or preferred ear for mobile phone use and the side of sudden sensorineural hearing loss. There was no correlation between the side of the sudden sensorineural hearing loss (preferable or non-preferable for mobile phone use) and audiometric characteristics.

No correlation was found between the laterality of ears used for mobile phone and sudden sensorineural hearing loss.

In order to achieve a faster and more reliable anterior rhinomanometric evaluation, nasal skin was prepared using benzoin tincture solution, which provides simpler and better adhesion of the foam tape to the nasal skin.

Two consecutive anterior rhinomanometry measurements were made, one with and one without benzoin tincture application.

The average time taken to perform classic foam tape anterior rhinomanometry without benzoin tincture application was 281.32 seconds, and the average coefficients of variation for the right and left passages were 7.48 and 7.59 per cent, respectively. When benzoin tincture was used, the average time taken for completion of the tests was 121.24 seconds, and the average coefficients of variation for the right and left passages were 2.17 and 2.32 per cent.

The use of benzoin tincture to clean the nasal skin before placing foam tape shortens the procedure duration and significantly increases test reliability.

To investigate the surgical and audiological outcomes of the Bonebridge transcutaneous bone conduction hearing implant among children with congenital aural atresia.

Six children were recruited and underwent Bonebridge transcutaneous bone conduction implant surgery. The patients’ audiometric thresholds for air conduction, bone conduction and sound-field tests were assessed pre-operatively and at six months post-operatively. Patients’ satisfaction was assessed at six months post-operatively with the Hearing Device Satisfaction Scale.

No major complications were reported. Mean aided sound-field thresholds improved post-operatively by more than 30 dB for 0.5–4 kHz (p < 0.05). Mean unaided air conduction and bone conduction thresholds differed by less than 5 dB post-operatively (compared to pre-operatively) for 0.5–4 kHz; these findings were not significant (p > 0.05). All patients were satisfied (scores were over 90 per cent) with the implant in terms of functional outcome and cosmetic appearance.

Bonebridge transcutaneous bone conduction implant surgery is safe and effective among children with congenital aural atresia with conductive hearing loss.

To evaluate the nasal functions of patients with unilateral chronic otitis media using rhinomanometry, comparing chronic otitis media sides with healthy sides, chronic otitis media patients with cholesteatoma and without cholesteatoma, and patients with healthy individuals.

This prospective study included 102 patients with unilateral chronic otitis media (48 with and 54 without cholesteatoma). The control group comprised 40 individuals without any ear or nasal pathologies. All patients underwent active anterior rhinomanometry to measure nasal airway resistance and a saccharin test to measure mucociliary transport times.

There were no significant differences in nasal airway resistance and mucociliary transport time between the chronic otitis media sides and unaffected sides in the 102 patients (p = 0.72 and p = 0.28, respectively), between the non-suppurative chronic otitis media patients (without cholesteatoma) and chronic otitis media with cholesteatoma patients (p > 0.05), or between the study and control groups (p > 0.05).

The present study, with a larger sample size compared to previously published literature, supports the conclusion that unilateral nasal obstruction is unlikely to lead to chronic otitis media on the same side. The results also suggest that nasal functions do not contribute to the development of cholesteatoma.

Totally endoscopic ear surgery and endoscope-assisted microsurgery are still new concepts, with relatively few centres in the UK performing them. Advantages include better visualisation of difficult to reach areas, such as the sinus tympani, and limited external incisions. This paper reports our short-term outcomes for endoscopic middle-ear surgery.

A prospective review was conducted of the first 103 consecutive patients undergoing totally endoscopic ear surgery or endoscope-assisted microsurgery in 1 centre performed by 1 operator. The outcomes assessed were: tympanic membrane healing, audiological data and complications.

Twenty-five patients underwent endoscope-assisted microsurgery, while 78 had totally endoscopic ear surgery. There were no reported cases of dead ear or permanent facial nerve palsy. The average air–bone gap following stapedectomy was 7.38 dB. The tympanic membrane healing rate was 89 per cent.

Our results confirm that endoscopic middle-ear surgery is safe, and the short-term outcomes are comparable with conventional surgery.

Totally endoscopic ear surgery is a relatively new method for managing chronic ear disease. This study aimed to test the null hypothesis that open and endoscopic approaches have similar direct costs for the management of attic cholesteatoma, from an Australian private hospital setting.

A retrospective direct cost comparison of totally endoscopic ear surgery and traditional canal wall up mastoidectomy for the management of attic cholesteatoma in a private tertiary setting was undertaken. Indirect and future costs were excluded. A direct cost comparison of anaesthetic setup and resources, operative setup and resources, and surgical time was performed between the two techniques.

Totally endoscopic ear surgery has a mean direct cost reduction of AUD$2978.89 per operation from the hospital perspective, when compared to canal wall up mastoidectomy.

Totally endoscopic ear surgery is more cost-effective, from an Australian private hospital perspective, than canal wall up mastoidectomy for attic cholesteatoma.

To examine the impact of temporal bone virtual reality surgical simulator use in the undergraduate otorhinolaryngology curriculum.

Medical students attended a workshop involving the use of a temporal bone virtual reality surgical simulator. Students completed a pre-workshop questionnaire on career interests. A post-workshop questionnaire evaluated the perceived usefulness and enjoyment of the virtual reality surgical simulator experience, and assessed changes in their interest in ENT.

Thirty-two fifth-year University of Auckland medical students were recruited. The majority of students (53.1 per cent) had already chosen their career path. The simulator experience was useful for: stimulating thoughts around career plans (71.9 per cent), providing hands-on experience (93.8 per cent) and teaching disease processes (93.8 per cent). After the workshop, 53.1 per cent of students were more interested in a career in ENT.

Virtual reality may be a fun and engaging way of teaching ENT. Furthermore, it could help guide student career planning.

Procedures of limited clinical value require pre-authorisation in the National Health Service, of which rhinoplasty and septorhinoplasty are two such operations. This study surveyed clinical commissioning groups within England to document the variable eligibility criteria for rhinoplasty and septorhinoplasty.

In February 2016, a letter was sent to 209 clinical commissioning groups requesting their rhinoplasty and septorhinoplasty commissioning criteria.

A total of 200 clinical commissioning groups responded. Although 89.5 per cent allow septorhinoplasty in the presence of nasal obstruction, further criteria, such as documented health problems resulting from nasal blockage, severe functional impairment or a specific percentage of blockage, must be shown for septorhinoplasty to be authorised by most of the clinical commissioning groups.

There is great variation within individual clinical commissioning groups in England regarding the criteria for septorhinoplasty and rhinoplasty. Some criteria seem not to be clinically relevant and difficult to demonstrate. It is recommended that the guidelines are reviewed and harmonised nationally in future revisions.

To determine whether patients within an otolaryngology department presenting with asymmetrical sensorineural hearing loss and/or unilateral tinnitus can be safely and cost-efficiently screened for acoustic neuroma by audiologists as a first or only point of contact.

A prospective case series and cost analysis were conducted at a tertiary referral centre. Between April 2013 and March 2017, 1126 adult patients presented to the audiology department with asymmetrical sensorineural hearing loss and/or unilateral tinnitus. All were screened for acoustic neuroma with magnetic resonance imaging, based on pre-determined criteria. The main outcome measure was the presence of acoustic neuroma or other pathology on magnetic resonance imaging.

Twenty-five patients (2.22 per cent) were found to have an acoustic neuroma (size range: 3–20 mm) and were referred to the otolaryngologist for further assessment. The remaining patients were appropriately managed and discharged by the audiologists without ENT input. This resulted in an overall cost saving of £164 850.

Patients with asymmetrical sensorineural hearing loss and/or unilateral tinnitus can be safely screened for acoustic neuroma and independently managed by audiologists as a first or only point of contact, resulting in considerable departmental cost savings.

The correlation between objective and subjective nasal obstruction is poor, and dissatisfaction rates after surgery for nasal obstruction are high. Accordingly, novel assessment techniques may be required. This survey aimed to determine patient experience and preferences for the measurement of nasal obstruction.

Prospective survey of rhinology patients.

Of 72 questionnaires distributed, 60 were completed (response rate of 83 per cent). Obstruction duration (more than one year) (χ2 = 13.5, p = 0.00024), but not obstruction severity, affected willingness to spend more time being assessed. Questionnaires (48 per cent) and nasal inspiratory peak flow measurement (53 per cent) are the most commonly used assessment techniques. Forty-nine per cent of participants found their assessment unhelpful in understanding their obstruction. Eighty-two per cent agreed or strongly agreed that a visual and numerical aid would help them understand their blockage.

Many patients are dissatisfied with current assessment techniques; a novel device with visual or numerical results may help. Obstruction duration determines willingness to undergo longer assessment.

Grommet insertion is a common surgical procedure in children. Long waiting times for grommet insertion are not unusual. This project aimed to streamline the process by introducing a pathway for audiologists to directly schedule children meeting National Institute for Health and Care Excellence Clinical Guideline 60 (‘CG60’) for grommet insertion.

A period from June to November 2014 was retrospectively audited. Mean duration between the first audiology appointment and grommet insertion was 294.5 days (median = 310 days). Implementing the direct-listing pathway reduced the duration between first audiology appointment and grommet insertion (mean = 232 days; median = 231 days). There has been a reduction in the time between the first audiology appointment and surgery (mean difference of 62.5 days; p = 0.024), and a reduction in the time between second audiology appointment and surgery (28 days; p = 0.009).

Direct-listing pathways for grommet insertion can reduce waiting times and expedite surgery. Implementation involves a simple alteration of current practice, adhering to National Institute for Health and Care Excellence Clinical Guideline 60. The ultimate decision regarding surgery still rests with ENT specialists.

Multi-layer reconstruction has become standard in endoscopic skull base surgery. The inlay component used can vary among autografts, allografts, xenografts and synthetics, primarily based on surgeon preference. The short- and long-term outcomes of collagen matrix in skull base reconstruction are described.

A case series of patients who underwent endoscopic skull base reconstruction with collagen matrix inlay were assessed. Immediate peri-operative outcomes (cerebrospinal fluid leak, meningitis, ventriculitis, intracranial bleeding, epistaxis, seizures) and delayed complications (delayed healing, meningoencephalocele, prolapse of reconstruction, delayed cerebrospinal fluid leak, ascending meningitis) were examined.

Of 120 patients (51.0 ± 17.5 years, 41.7 per cent female), peri-operative complications totalled 12.7 per cent (cerebrospinal fluid leak, 3.3 per cent; meningitis, 3.3 per cent; other intracranial infections, 2.5 per cent; intracranial bleeding, 1.7 per cent; epistaxis, 1.7 per cent; and seizures, 0 per cent). Delayed complications did not occur in any patients.

Collagen matrix is an effective inlay material. It provides robust long-term separation between sinus and cranial cavities, and avoids donor site morbidity, but carries additional cost.

The application of moisture to the ear is anecdotally claimed to relieve the pain from otic barotrauma that can arise during aircraft descent. This claim was tested in a randomised double-blind study on an aircraft with eight participants heavily predisposed to barotrauma.

On the outward flight, half the participants wore ‘active’ devices that applied moisture to the external ear; the remainder wore placebo devices that contained no moisture, but were otherwise identical. On the return flight, the groups were reversed. Participants wore the devices from just before descent until landing, unless they experienced symptoms of barotrauma, in which case they switched to what they knew was an active device.

There were no significant differences between conditions regarding the appearance of the tympanic membrane on landing or the discomfort levels immediately before and after any switch.

Applying moisture is ineffective for passengers heavily predisposed to otic barotrauma.

To assess counts of α4 and α7 nicotinic acetylcholine receptors in nasal polyps of adults with or without long-term exposure to cigarette tobacco smoke.

Twenty-two patients with and 22 patients without exposure to cigarette tobacco smoke participated in the study. After endoscopic polypectomy, the fragments of the nasal polyps were analysed by immunohistochemistry.

Compared to patients with no exposure, patients with exposure showed higher counts of α4 and α7 nicotinic acetylcholine receptors (t-test, p < 0.05). However, in patients with no exposure, multivariate analysis showed gender dimorphism, with lower counts in males than in females, and no influence from other variables (analysis of covariance, p > 0.05).

Exposure to cigarette tobacco smoke may induce increased counts of α4 and α7 nicotinic acetylcholine receptors in nasal polyps of adults, with lower counts in males than females without exposure to tobacco smoke.

To validate a newly introduced cartilage rim augmented temporalis fascia tympanoplasty technique by statistically comparing it with the morphological and audiological outcomes of traditional temporalis fascia tympanoplasty.

A retrospective comparative study was conducted on 115 patients who underwent tympanoplasty during 2013 and 2015. Fifty-eight patients underwent temporalis fascia tympanoplasty and 57 underwent cartilage rim augmented fascia tympanoplasty.

In the cartilage fascia group, graft healing was achieved in 94.7 per cent of cases; in the temporalis fascia group, the graft take-up rate was 70 per cent. In those with a normal ossicular chain, the post-operative air–bone gap was within 20 dB in 92.6 per cent of cartilage fascia group cases and in 69.7 per cent of the temporalis fascia group cases, which was a statistically significant difference. Among the defective ossicular chain cases, the post-operative air–bone gap was within 20 dB in 76.9 per cent in the cartilage fascia group, as against 57.1 per cent in the temporalis fascia group.

Cartilage rim augmented temporalis fascia tympanoplasty has a definite advantage over the temporalis fascia technique in terms of superior graft take up and statistically significant hearing gain in those with normal ossicular mobility.

This study aimed to present the clinical features and surgical outcomes of juvenile nasopharyngeal angiofibroma patients who were surgically treated.

The medical records of 48 male patients histologically confirmed as having juvenile nasopharyngeal angiofibroma, who underwent transnasal endoscopic surgery between 2005 and 2016, were retrospectively reviewed.

The overall recurrence rate was 20.8 per cent; however, the recurrence rate differed significantly between patients diagnosed aged less than 14 years (34.7 per cent) and more than 14 years (8 per cent) (p < 0.05). Advanced-stage tumours (Radkowski stage of IIC or more, and Önerci stage of III or more) were more aggressive than earlier stage tumours (p < 0.05 and p < 0.01, respectively). Pre-operative embolisation significantly prolonged mean hospitalisation duration, but had no effect on intra-operative blood loss in patients with advanced-stage tumours (p < 0.001 and p = 0.09, respectively).

The findings show that transnasal endoscopic surgery could be considered the treatment of choice for juvenile nasopharyngeal angiofibroma. Patients diagnosed when aged less than 14 years and those with advanced-stage tumours are at risk of recurrence, and should be monitored with extreme care.

To compare nasal mucociliary clearance in adult non-smokers, cigarette smokers and bidi smokers using the methylene blue dye test.

The study sample consisted of 20 non-smokers, 20 cigarette smokers and 20 bidi smokers (age range, 20–40 years). A single drop of the methylene blue dye was placed at the anterior end of the inferior turbinate of the participants’ nasal cavity. The distance travelled by the methylene blue in 15 minutes inside the nasal cavity was measured. Nasal mucociliary clearance of the three groups was compared using the Kruskal Wallis test.

Nasal mucociliary clearance was significantly decreased in bidi smokers as compared to cigarette smokers and non-smokers (p < 0.05). Multivariate analysis revealed a significant association between nasal mucociliary clearance and bidi smoking, number of cigarettes or bidis smoked per day, and pack-years (all p < 0.05).

Nasal mucociliary clearance measurement is a simple and useful index for assessing the effect of smoking on the mucociliary activity of nasal mucosa.

To evaluate the therapeutic effect that the titanium partial ossicular reconstruction prosthesis and autologous ossicles have on hearing loss after reconstruction of a damaged ossicular chain.

Forty-two medical records of treatments carried out from 2013 to 2015 for ossicular chain damage with facial nerve paralysis due to temporal bone fractures were reviewed. The study assessed: causes of damage, pre-operative pure tone audiometry findings, types of intra-operative ossicular chain damage, intra-operative ossicular chain repair methods (titanium partial ossicular reconstruction prosthesis or autologous ossicles) and post-operative pure tone audiometry results.

The titanium partial ossicular reconstruction prosthesis was used in 26 cases; the average air–bone gap was 32.3 ± 5.3 dB pre-operatively and 12.8 ± 5.3 dB post-operatively. Autologous ossicles were used in 16 cases; the average air–bone gap was 33.4 ± 4.5 dB pre-operatively and 17.8 ± 7.8 dB post-operatively.

Ossicular chain reconstruction is an effective way of improving hearing in patients with ossicular chain damage. The results suggest that repair with either the titanium partial ossicular reconstruction prosthesis or autologous ossicles can improve hearing following ossicular chain injury with facial nerve paralysis caused by a temporal bone fracture.

Possible therapeutic and protective benefits of intratympanic autologous serum application in amikacin-induced ototoxicity were investigated.

Twenty-four guinea pigs were separated equally into two groups: therapeutic (group A) and protective (group B). Transient evoked otoacoustic emissions were recorded before and after autologous serum application. Apoptotic cells were identified in the organ of Corti, spiral limbus and spiral ganglion by the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labelling (‘TUNEL’) method.

Transient evoked otoacoustic emission responses at 1, 1.4 and 2.8 kHz improved without significance after autologous serum application in group A (p > 0.05). A significantly protective effect of autologous serum was determined at 4 kHz in group B (p < 0.05). There were significantly fewer apoptotic cells at the spiral limbus in the therapeutic and protective groups compared to the control group (p < 0.05).

Autologous serum may offer protection against ototoxicity-induced hearing loss, but it cannot restore hearing. Immunohistochemically, autologous serum significantly decreases activation of the intrinsic pathway of pro-apoptotic signalling in mesenchymal cells compared to neurons and neurosensory cells.

This study aimed to evaluate patients with tinnitus in terms of mean platelet volume and platelet distribution width, and to explore neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio, recently reported in the literature as being possible inflammation markers.

This study comprised 64 tinnitus patients and 64 age-matched healthy controls. Statistical significance level was accepted as p < 0.05.

Mean platelet volume (t = 3.245, p = 0.002) and platelet distribution width (Z = 3.945, p < 0.001) were significantly higher in the patient group than the control group.

The results suggest that a prothrombotic condition might play a role in the pathophysiology of tinnitus.
