HYPOTHESIS
Using image-guided surgical techniques, we propose that an industrial robot can be programmed to safely, effectively, and efficiently perform a mastoidectomy.
BACKGROUND
Whereas robotics is a mature field in many surgical applications, robots have yet to be clinically used in otologic surgery despite significant advantages including reliability and precision.
METHODS
We designed a robotic system that incorporates custom software with an industrial robot to manipulate a surgical drill through a complex milling profile. The software controls the movements of the robot based on real-time feedback from a commercially available optical tracking system. The desired path of the drill to remove the desired volume of mastoid bone was planned using computed tomographic scans of cadaveric specimens and then implemented using the robotic system. Bone-implanted fiducial markers were used to provide accurate registration between computed tomographic and physical space.
RESULTS
A mastoid cavity was milled on 3 cadaveric specimens with a 5-mm fluted ball bit. Postmilling computed tomographic scans showed that, for the 3 specimens, 97.70%, 99.99%, and 96.05% of the target region was ablated without violation of any critical feature.
CONCLUSION
To the best of our knowledge, this is the first time that a robot has been used to perform a mastoidectomy. Although significant hurdles remain to translate this technology to clinical use, we have shown that it is feasible. The prospect of reducing surgical time and enhancing patient safety by replacing human hand-eye coordination with machine precision motivates future work toward translating this technique to clinical use.

Review
INTRODUCTION
Chronic suppurative otitis media (CSOM) is a common cause of hearing impairment and disability. Occasionally it can lead to fatal intracranial infections and acute mastoiditis, especially in developing countries.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for chronic suppurative otitis media in adults and in children? What are the effects of treatments for cholesteatoma in adults and in children? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2010 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 51 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review, we present information relating to the effectiveness and safety of the following interventions: topical ear cleansing, surgery for cholesteatoma, systemic antibiotics, topical antibiotics, topical antibiotics plus topical corticosteroids, topical antiseptics, topical corticosteroids, tympanoplasty (with or without mastoidectomy).

Review
Coccidioidomycosis involving the ear, mastoid bone, or both is uncommon. We describe 5 new cases from the United States and review 4 cases reported in the literature of otomycosis and mastoiditis caused by Coccidioides. Of the 9 cases, 8 were linked to residence in or travel to California. Two patients had poorly controlled diabetes mellitus, 7 had otomastoiditis, 1 had otitis externa without mastoid involvement, and 1 had mastoiditis without otic involvement. Four patients had concurrent or prior pulmonary coccidioidomycosis. Ipsilateral facial nerve palsies developed in 2 patients. All patients received antifungal treatment for varying durations, and 8 of the 9 patients underwent surgical debridement. Clinicians should consider coccidioidomycosis as a differential diagnosis for otomastoiditis in patients with geographic risks.

PURPOSE
It is unusual to have communication from the external auditory canal (EAC) directly to the mastoid, totally sparing the tympanum. These patients need a different surgical approach, a modified canal wall-down procedure, to completely clear the disease but fully preserve the tympanum. We present one such exceptional case.
CASE PRESENTATION
A 28-year-old lady presented with ear discharge for 1 year. Imaging confirmed the canal-mastoid fistula, but the entire tympanum was normal. We performed a modified-modified radical mastoidectomy.
CONCLUSIONS
Canal-mastoid fistula is an infrequent entity and may be idiopathic. Despite being evident on clinical examination, imaging aids in assessing size and location of the defect. Although EAC reconstruction may be attempted, the majority require a canal wall-down procedure.

Chronic mastoiditis and subperiosteal abscess are rarely seen nowadays in most countries. Thirty-four cases of mastoiditis were reviewed to find out the prevalence of chronic mastoiditis in the east coast of Malaysia. Twenty (58.82%) of these cases were a sequelae of chronic suppurative otitis media with cholesteatoma. All the patients with chronic mastoiditis were more than six years old. Forty-five percent of cases with chronic mastoiditis had a well pneumatized mastoid air cell on the unaffected side. The occurrence of chronic mastoiditis or cholesteatoma in a well pneumatized mastoid is not really as rare as was thought to be. X-ray of the mastoids is very useful in diagnosing patients with chronic mastoiditis and cholesteatoma. Mastoiditis is uncommon in adults and whenever a case is seen, an underlying pathology like cholesteatoma should be suspected.

Meta-Analysis Review
BACKGROUND
This is an update of a Cochrane review first published in The Cochrane Library in Issue 1, 2010.Ménière's disease is characterised by three major symptoms: vertigo, deafness, and tinnitus or aural fullness, all of which are discontinuous and variable in intensity. A number of surgical modalities, of varying levels of invasiveness, have been developed to reduce the symptoms of Ménière's disease, but it is not clear whether or not these are effective.
OBJECTIVES
To assess the effectiveness of surgical options for the treatment of Ménière's disease. All surgical interventions used in the treatment of Ménière's disease, either to alter the natural history of the disease or to abolish vestibular function, were considered for this review.
SEARCH METHODS
We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ICTRP and additional sources for published and unpublished trials. The date of the most recent search was 7 November 2012.
SELECTION CRITERIA
Randomised or quasi-randomised controlled studies of a surgical modality versus a placebo therapy in Ménière's disease.
DATA COLLECTION AND ANALYSIS
Two authors independently assessed trial quality and extracted data. We contacted study authors for further information.
MAIN RESULTS
The only surgical intervention which has been evaluated in randomised controlled trials and met the inclusion criteria was endolymphatic sac surgery. We identified two randomised trials, involving a total of 59 patients; one comparing endolymphatic sac surgery with ventilation tubes and one with simple mastoidectomy. Neither study reported any beneficial effect of surgery either in comparison to placebo surgery or grommet insertion.
AUTHORS' CONCLUSIONS
The two trials included in this review provide insufficient evidence of the beneficial effect of endolymphatic sac surgery in Ménière's disease.

Review
OBJECTIVES
The aim of this scoping review was to evaluate existing classifications of surgical procedures of the middle ear and mastoid and find a suitable classification that could serve as an international standard.
MATERIALS AND METHODS
Scoping review with a systematic literature search using reference tracking and a syntax including all surgical procedures in mastoid and middle ear surgery and their synonyms. Studies were selected based on inclusion and exclusion criteria.
RESULTS
Eleven reported classifications were included; six of which focused on middle ear surgery, two on mastoid surgery, and three on both. However, none of the classifications included all current surgical procedures of mastoid and middle ear surgery.
CONCLUSION
Many classifications have been proposed for innumerable surgical techniques in middle ear and mastoid surgery. Some are outdated, some are incomplete, most are not widely accepted, and only few correspond with all current surgical techniques.
