Endoscopic hydro-mastoidectomy, in which mastoidectomy is performed underwater, can be employed during transcanal endoscopic ear surgery for cholesteatoma removal. It was hypothesised that endoscopic hydro-mastoidectomy might take less time than endoscopic non-underwater mastoidectomy because the endoscope does not need to be removed for cleaning.

This study compared the mastoidectomy and total operative durations between the endoscopic hydro-mastoidectomy (n = 25) and endoscopic non-underwater drilling (control, n = 8) groups. Moreover, it compared the size of resected areas of the external auditory canal between the two groups.

The mastoidectomy time of the endoscopic hydro-mastoidectomy group was significantly shorter than that of the control group (p < 0.01). The total operative time did not differ significantly between the endoscopic hydro-mastoidectomy and control groups (p = 0.17). The resected area was significantly larger in the endoscopic hydro-mastoidectomy group than in the control group (p < 0.05).

Endoscopic hydro-mastoidectomy enables more extensive bone resection within a shorter period.

In order to remove a cholesteatoma in the mastoid under transcanal endoscopic ear surgery, it is necessary to perform transcanal endoscopic mastoidectomy. Bone dust and blood, however, obscure the surgical field. A novel endoscopic hydro-mastoidectomy technique was developed, in which the operator performs the mastoidectomy ‘underwater’ using a lens cleaning system that provides saline perfusion in the surgical space.

A curved round coarse diamond bur is attached to an otological drill. A lens cleaning sheath is fitted to the endoscope. The surgeon controls the infusion of saline solution by stepping on a footswitch of the power console.

Endoscopic hydro-mastoidectomy washes out bone dust and blood from the surgical field, improving the surgical view during mastoidectomy. Additionally, the operator can easily control the flow of saline perfusion.

This technique provides a clear surgical view by washing out bone dust and blood from the surgical area. The setup for endoscopic hydro-mastoidectomy technique is easy and the operator needs only to buy sheaths if they already own the power console, as many otological and rhinological surgeons do.

Advanced hypopharyngeal carcinoma has a dismal prognosis. The optimal treatment for these patients remains under debate. This systematic review aimed to compare survival following surgical and non-surgical treatments.

A systematic review was conducted of randomised studies, with a descriptive analysis of retrospective observational studies.

Two randomised trials and 11 observational studies were included in the review. A meta-analysis of randomised trials reported a hazard ratio of 0.89 for overall survival in favour of surgical treatment (p = 0.44). Neither treatment was favoured in terms of overall survival. Observational studies did not report a survival advantage with either treatment. The five-year larynx preservation rates for non-surgically treated patients were between 38 and 58 percent.

Chemoradiotherapy offers similar survivorship compared to surgery in advanced disease, while also making larynx preservation feasible. It can be used as a treatment in all patients as an alternative to surgery.

Oropharyngeal cancer is increasing in prevalence in the UK and this is thought to be due to the emergence of disease related to human papilloma virus.

A literature review was conducted on the diagnosis and latest management of oropharyngeal cancer.

In non-smokers, human papilloma virus related disease is thought to have better outcomes, but this casts doubt on previous research which did not stratify patients according to human papilloma virus status. However, this theory provides a route for researchers to risk stratify and de-escalate treatments, and hence reduce treatment burden. In addition, the emergence of minimally invasive transoral techniques allows surgeons to remove large tumours without many of the side effects associated with radical (chemo)radiotherapy.

The emergence of human papilloma virus related disease and minimally invasive techniques have led the clinical and academic community to reconsider how oropharyngeal cancer is managed. Comparative and risk-stratification trials are urgently required and ongoing.

To present the profile of patients undergoing surgical treatment for vertigo at a contemporary institutional vertigo clinic.

A retrospective analysis of clinical charts.

The charts of 1060 patients, referred to an institutional vertigo clinic from January 2003 to December 2012, were studied. The clinical profile and long-term outcomes of patients who underwent surgery were analysed.

Of 1060 patients, 12 (1.13 per cent) were managed surgically. Of these, disease-modifying surgical procedures included perilymphatic fistula repair (n = 7) and microvascular decompression of the vestibular nerve (n = 1). Labyrinth destructive procedures included transmastoid labyrinthectomy (n = 2) and labyrinthectomy with vestibular nerve section (n = 1). One patient with vestibular schwannoma underwent both a disease-modifying and destructive procedure (translabyrinthine excision). All patients achieved excellent vertigo control, classified as per the American Academy of Otolaryngology – Head and Neck Surgery 1995 criteria.

With the advent of intratympanic treatments, surgical treatments for vertigo have become further limited. However, surgery with directed intent, in select patients, can give excellent results.

Revision laryngeal framework surgery is usually performed for medialisation laryngoplasty failure, rather than for failure after arytenoid adduction. We describe a new method for revision arytenoid adduction surgery, performed by directly pulling the lateral cricoarytenoid muscle (‘lateral cricoarytenoid muscle pull surgery’).

We describe a case of revision laryngeal framework surgery, present a literature review and describe the advantages of lateral cricoarytenoid muscle pull surgery over the original method of arytenoid adduction using a posterior approach.

Medialisation laryngoplasty combined with arytenoid adduction was performed following unilateral vocal fold paralysis from mediastinal surgery, resulting in severe glottic insufficiency. The patient's voice improved after the initial surgery, but had deteriorated 18 months later. Revision surgery was performed using lateral cricoarytenoid muscle pull surgery, and her voice recovered normally in terms of perceptual impression. The post-operative course was uneventful for 10 months following revision surgery.

To our knowledge, this is the first case of revision arytenoid adduction performed using a lateral cricoarytenoid muscle pull approach. Lateral cricoarytenoid muscle pull surgery should therefore be considered as a new fenestration approach for arytenoid adduction.

The loading of bone-anchored hearing system sound processors usually occurs two to three months after surgical implant. This study examined a new bone-anchored hearing system coupling mechanism that permits loading at two weeks post-implantation without compromising osseointegration.

Twenty implants were implanted into 15 patients. The interval between operation and time of processor loading was recorded, along with the cause of any delay and any late complications.

Two patients were fitted with implants at seven and nine weeks. The delay was a result of administrative errors; the patients reported no skin problems. Of the remaining 17 implants, 8 processors were fitted at 2 weeks, 1 at 3 weeks, 4 at 4 weeks, 3 at 7 weeks and 1 at 8 weeks. For those nine implants fitted later than two weeks, the delay was because of incomplete skin healing.

The Oticon Medical Xpress system allowed processor loading at two weeks post-operatively, providing skin healing was adequate. Early loading occurred in approximately half of the patients. All patients were fitted within the two to three months traditionally allowed. Prolonged skin healing time was the main reason for the delayed fitting of sound processors.

New surgical techniques and devices have been described that decrease post-tonsillectomy morbidities. This study aimed to compare the two most popular tonsillectomy techniques.

Forty children underwent tonsillectomies using both the thermal welding and cold dissection techniques. In each patient, one side was removed with thermal welding and the other was removed with cold dissection.

There was a significant decrease in intra-operative blood loss, and the mean operation time was significantly lower on the thermal welding side compared with the cold dissection side. On the cold dissection side, tissue healing (i.e. the rate of complete tissue healing) was better and less pain was reported compared with the thermal welding side. However, there were no significant differences between the two techniques in terms of throat pain scores on the 1st, 3rd or 14th day post-operatively, or tissue healing scores on any of the post-operative days assessed.

Cold dissection resulted in better tissue healing and lower pain scores than thermal welding, but thermal welding was associated with less intra-operative blood loss and lower mean operation time than cold dissection.

This study aimed to evaluate the efficacy of post-operative voice therapy after phonomicrosurgery for vocal polyp removal.

The study retrospectively enrolled 55 consecutive patients who had undergone voice therapy after phonomicrosurgery for vocal polyp removal occurring between June 2010 and June 2011. A historical group of 63 similar patients not receiving voice therapy was used as an external control. We compared voice analysis parameters and Voice Handicap Index scores for the two groups.

Most objective and subjective voice outcome parameters were significantly improved after surgical treatment. Although the study and control groups showed no significant difference regarding objective parameters (using acoustic and aerodynamic analysis) or the subjective parameters assessed using the grade-roughness-breathiness-asthenia-strain scale, the study group had significantly better final Voice Handicap Index scores.

Following surgery for vocal polyps, post-operative voice therapy can improve patients' vocal discomfort, emotional responses and everyday self-perception.

To report the clinical characteristics and treatment outcomes of indolent paranasal mucormycosis in immunocompetent individuals.

A retrospective review of four immunocompetent patients with indolent mucormycosis of the paranasal sinus managed by endoscopic sinus surgery only was performed. One year of regular follow up comprised angled endoscopy and repeated paranasal sinus computed tomography three months after surgery.

Clinical symptoms were non-specific. Pre-operative paranasal sinus computed tomography showed opacification of the unilateral maxillary sinus with focal calcification but without bony destruction or extension to the orbit or cranium. All patients underwent endoscopic sinus surgery without administration of antifungal agents. There was no recurrence on regular clinical and radiological follow up.

For indolent paranasal mucormycosis in immunocompetent patients, endoscopic sinus surgery can be the treatment of choice, and the administration of antifungal drugs may not be necessary.

More than a century has passed since Emil Theodor Kocher first described the use of ‘Kocher's thyroid dissector’ to secure the superior thyroid pedicle.

Despite the technological advances in thyroid surgery, the dissector remains an extremely useful instrument. This paper describes a modified use of the dissector, and reports on how this facilitates safer and easier surgery.

Application of this simple, modified technique can improve the safety and efficiency of thyroid surgery, with negligible financial outlay.

To evaluate residual tumour occurrence after vestibular schwannoma surgery, based on intra-operative registration and magnetic resonance imaging one year post-operatively.

Patients undergoing translabyrinthine surgery for vestibular schwannoma in Denmark between 1976 and 2008 were registered in a national database covering 5.5 million inhabitants.

Translabyrinthine surgery was undertaken on 1143 patients. Of these, 978 had total, 140 near-total and 25 subtotal tumour excision, as assessed intra-operatively by the surgeon. One year after surgery, 65 per cent of small tumour remnants and 11 per cent of large tumour remnants were not visible on magnetic resonance imaging. The mean pre-operative size was significantly smaller for totally excised tumours, compared with near-totally and subtotally excised tumours. Revision surgery was performed for 14 patients (1.2 per cent), of whom 2 had received total, 5 near-total and 6 subtotal excisions initially.

Most residual tumours disappear spontaneously, probably due to devascularisation. Few patients with a small residual vestibular schwannoma will require revision surgery or secondary radiotherapy.

Numerous techniques have been described to manage the skin and other soft tissues during bone-anchored hearing aid insertion. Previously, generally accepted techniques have sometimes led to distressing alopecia and soft tissue defects. Now, some surgeons are rejecting the originally described split skin flap in favour of a less invasive approach.

To investigate bone-anchored hearing aid placement utilising a single, linear incision with either no or minimal underlying soft tissue reduction.

Thirty-four adults were prospectively enrolled to undergo single-stage bone-anchored hearing aid placement with this modified technique. A small, linear incision was used at the standard position and carried down through the periosteum. Standard technique was then followed with placement of an extended length abutment. Patients were reviewed regularly to assess wound healing, including evaluation with Holgers' scale.

Only 14.7 per cent of patients had a reaction score of 2 or higher. Most complications were limited to minor skin reactions that settled with silver nitrate cautery and/or antibiotics. None required revision surgery for tissue overgrowth, and there were no implant failures.

Our results suggest this to be a simple and effective insertion technique with favourable cosmesis and patient satisfaction.

We report two extremely rare cases of symptomatic nasopharyngeal branchial cleft cyst treated by powered instrument assisted marsupialisation.

Case report and literature review concerning nasopharyngeal branchial cleft cyst and surgical treatment methods.

The first case was a two-year-old boy with a 1 × 2 cm, cystic, oropharyngeal mass, who also had severe snoring and sleep apnoea. The second case was a 56-year-old man with right nasal obstruction and a sensation of fullness in the right ear. In both cases, we performed endoscopic marsupialisation using a powered instrument. There was no recurrence in either case over two years of follow up.

Powered instrument marsupialisation is a simple, effective and less invasive technique for the treatment of nasopharyngeal branchial cleft cyst.

To study the outcome of endonasal endoscopic surgery for adenoid cystic carcinoma of the sinonasal tract over a five-year follow-up period.

Retrospective analysis.

Four consecutive patients with adenoid cystic carcinoma of the sinonasal tract, who had undergone endonasal endoscopic surgery, were reviewed regarding age at diagnosis, sex, primary site, tumour-node-metastasis staging, treatment modalities, histopathological findings, duration of follow up, distant metastases and treatment outcome.

All patients were diagnosed at an advanced stage and had post-operative adjuvant radiotherapy. Three patients underwent endoscopic endonasal resection and one endoscopic assisted craniofacial resection. The most common primary site was the ethmoid sinus (three patients). Three patients had no evidence of recurrence. One patient who had undergone partial clearance via endoscopic endonasal resection developed cervical node metastases a year after treatment; this patient also developed distant metastases.

Adenoid cystic carcinoma is difficult to treat. Sinonasal tract tumours can be resected via endoscopic endonasal resection or endoscopic assisted craniofacial resection, but prolonged follow up is advisable. Radiotherapy is an important adjuvant treatment.

To describe a rare case of multiple anatomical variations in the sinonasal skeleton of an adolescent with chronic rhinosinusitis, together with its successful surgical management.

A 15-year-old male adolescent was referred with a 3-year history of nasal blockage and hyposmia. His symptoms did not improve on maximal medical therapy. A pre-operative computed tomography scan revealed numerous anatomical variations in his nose and paranasal sinuses. He underwent neuronavigation-assisted endoscopic sinus surgery without complication, and with subsequent resolution of his symptoms at 10 months.

Chronic rhinosinusitis in children offers its own set of unique surgical challenges. The effectiveness and safety of sinus surgery in this population can be improved through the knowledge of anatomical variants, and is aided by the use of image guidance systems.

Chondrodermatitis nodularis chronica helicis is a common benign condition of the pinna. It presents as a painful, well demarcated nodule on the pinna that may be associated with surrounding erythema or an overlying crust.

This paper describes techniques for the excision of chondrodermatitis nodularis chronica helicis on both the helix and anti-helix, and reconstruction of the defect.

Both methods give an excellent cosmetic result and can be performed under local anaesthetic. Excising and smoothing down the cartilage decreases the likelihood of recurrence as a smooth contour to the ear is achieved.

Hereditary haemorrhagic telangiectasia is an autosomal dominant condition characterised by multiple venous malformations of the skin and mucous membranes which can bleed on contact. A Young's procedure is used to control severe epistaxis in patients with this condition. However, there has been no previous report of a reversal of Young's procedure in such a patient.

A patient with hereditary haemorrhagic telangiectasia had his Young's procedure reversed under general anaesthetic by dividing the mucocutaneous flaps. Nasal vestibule patency was maintained using a custom-made silicone nasal mould. Intra-operative photographs show the patient's nasal mucosa shortly following reversal of his Young's procedure, and also illustrate the creation of the custom-made nasal mould.

Stopping airflow through the nasal cavity via a Young's procedure prevents the telangiectasia from bleeding but does not make them disappear completely. Young's procedure does not seem to have any long-lasting effect on the nasal mucosa of patients with hereditary haemorrhagic telangiectasia.

We present a case series with airway compromise due to bilateral abductor vocal fold paralysis or fixation, treated with unilateral transverse cordotomy.

Of eight consecutive patients with dyspnoea due to bilateral paramedian vocal fold immobility, seven underwent unilateral transverse cordotomy between August 2006 and April 2010 at University Hospital of South Manchester, UK. Airway and voice outcomes were compared before and after surgery.

All seven treated cases derived subjective airway function improvement; there was no aspiration. The eighth case had inadequate access. None of the seven treated patients required contralateral cordotomy or permanent tracheostomy. One treated case required a temporary tracheostomy; unilateral transverse cordotomy facilitated eventual decannulation. Two patients died of cancer at five and six weeks, variously. At a mean follow up of 22 months, four cases showed unchanged or slightly worse Voice Symptom Scale and Grade-Roughness-Breathiness-Asthenia-Strain scale scores.

In patients with bilateral abductor vocal fold immobility, unilateral transverse cordotomy results in improved dyspnoea with either no voice change or only slight worsening. This is a more conservative procedure than bilateral transverse cordotomy, with the potential for better preservation of voice and breath support.
