A case series of complicated infective otitis media requiring surgery in adults

<p><b>INTRODUCTION</b>With the advent of antibiotics, complications of otitis media have become less common. It is crucial for physicians to recognise otitis media and treat its complications early. Herein, we present our institution's experience with patients who required emergency surgical intervention for complications of otitis media.</p><p><b>METHODS</b>Data on patients who underwent emergency surgery for complications of otitis media from 2004 to 2011 was retrieved from the archives of the Department of Otolaryngology, Changi General Hospital, Singapore.</p><p><b>RESULTS</b>A total of 12 patients (10 male, two female) underwent emergency surgery for complications of otitis media. The median age of the patients was 25 years. Otalgia, otorrhoea, headache and fever were the main presenting symptoms. Extracranial complications were observed in 11 patients, and six patients had associated intracranial complications. The primary otologic disease was acute otitis media in six patients, chronic otitis media without cholesteatoma in three patients and chronic otitis media with cholesteatoma in three patients. Mastoidectomy and drainage of abscess through the mastoid, with insertion of grommet tube, was the main surgical approach. Two patients required craniotomy. The mean length of hospital stay was 16.2 days and the mean follow-up period was 16.3 months. Five patients had residual conductive hearing loss; two patients with facial palsy had full recovery.</p><p><b>CONCLUSION</b>Otitis media can still result in serious complications in the post-antibiotic era. Patients with otitis media should be monitored, and prompt surgical intervention should be performed when necessary to attain good outcomes.</p>

Current evidence for endolymphatic sac surgery in the treatment of Meniere's disease: a systematic review

This paper aims to identify emerging evidence for endolymphatic sac surgery (ESS) in the treatment of Meniere's disease since the landmark study by Thomsen et al, published in 1998 (conducted from 1981 to 1989). Using the MEDLINE database (PubMed), a systematic review of the literature published from January 1990 to June 2014 was performed. We included all English-language, peer-reviewed randomised controlled trials (RCTs) and controlled studies. Single-arm cohort studies were included if the sample size was ≥ 90 with a response rate > 60%. Altogether, 11 studies fulfilled our inclusion criteria; one was an RCT, two were controlled trials and eight were single-arm cohort studies. There currently exists a low level of evidence for the use of ESS in the treatment of Meniere's disease. Further studies, in particular RCTs and/or controlled studies, are required to fully evaluate this modality. However, there are difficulties in designing a valid placebo and achieving adequate blinding of observers and investigators.

Bell's palsy in Singapore: a view from the patient's perspective

<p><b>INTRODUCTION</b>Bell's palsy is a well-recognised disease with robust research on its possible aetiologies and epidemiology, but scant information on patients' concerns and concepts regarding the condition is available. We aimed to evaluate the ideas, concerns and expectations of patients with Bell's palsy in Singapore.</p><p><b>METHODS</b>A cross-sectional study was conducted at a single tertiary-care hospital in Singapore. Participants were all patients with newly diagnosed Bell's palsy referred to the otolaryngology department either from the emergency department or by general practitioners. Participants were given a self-administered questionnaire and their facial nerve palsies were graded by the consultant doctor.</p><p><b>RESULTS</b>A total of 52 patients were recruited, of which 41 were available for analysis. 78.0% of patients were concerned that they were having a stroke upon presentation of the symptoms. Other beliefs about the cause of the disease included overwork or stress (36.6%), something that the patient had eaten (9.8%) and supernatural forces (2.4%). About 50% of patients had tried some form of complementary or alternative therapy other than the steroids/medicines prescribed by their general practitioner or emergency physician. While 39.0% of patients agreed that the Internet had helped them understand more about their condition in addition to the information provided by the physician, 9.8% of them specifically disagreed with this statement.</p><p><b>CONCLUSION</b>We have found that patients with Bell's palsy in Singapore are not very knowledgeable about the disease. Although the Internet is a useful resource, a physician's explanation of the disease and its natural progression remains of utmost importance.</p>

Head and neck cancers masquerading as deep neck abscesses

Deep neck space abscesses are common otolaryngological emergencies, and prompt incision and drainage is the treatment of choice. Head and neck cancers often present with cervical metastases that may become secondarily infected. Clinical presentation is similar to a deep neck abscess. Surgical drainage of such collections has implications on subsequent treatment. In this case series, we describe six cases with this unusual presentation that were subsequently found to have a head and neck malignancy, and where three patients had their abscesses treated surgically. We aim to raise awareness of this unusual presentation of a head and neck carcinoma, and to avoid a potential pitfall in the management of deep neck abscess.

Sphenoidal mucocele presenting as acute cranial nerve palsies

Sphenoidal sinus mucoceles are indolent lesions that, when sufficiently large, can compress on the optic canal or superior orbital fissure, rapidly causing loss of vision, optic neuropathy, ptosis, pain, ophthalmoplegia, and diplopia. We herein report a 72-year-old gentleman who presented acutely with Cranial Nerve II, III, and IV palsies secondary to a sphenoidal sinus mucocele that was confirmed on magnetic resonance imaging and successfully treated with endoscopic drainage. This cause of orbital apex syndrome is important for clinicians to know as early diagnosis and treatment is critical in recovering visual potential

15th Yahya Cohen Memorial Lecture - the relationship between the air-bone gap and the size of superior semicircular canal dehiscence

<p><b>INTRODUCTION</b>This study aimed to examine the relationship between the air-bone gap (ABG) and the size of the superior semicircular canal dehiscence (SSCD) as measured on a computed tomography (CT) scan.</p><p><b>MATERIALS AND METHODS</b>The study design was a case series with chart review. Twenty-three patients (28 ears) from a tertiary referral centre were diagnosed with SSCD. The size of the dehiscence on CT scans and the ABG on pure-tone audiometry were recorded.</p><p><b>RESULTS</b>The size of the dehiscence ranged from 1.0 to 6.0 mm (mean, 3.5 ± 1.6 mm). Six ears with a dehiscence measuring less than 3.0 mm did not have an ABG (0 dB). The remaining 18 ears showed an average ABG at 500, 1000, and 2000 Hz (AvABG(500-2000)) ranging from 3.3 to 27.0 dB (mean, 11.6 ± 5.7 dB). The analysis of the relationship between the dehiscence size and AvABG(500-2000) revealed a correlation of R(2) = 0.828 (P <0.001, quadratic fit) and R(2) = 0.780 (P <0.001, linear fi t). Therefore, the larger the dehiscence, the larger the ABG at lower frequencies on pure-tone audiometry.</p><p><b>CONCLUSION</b>In SSCD patients, an ABG is consistently shown at the low frequency when the dehiscence is larger than 3 mm. The size of the average ABG correlates with the size of the dehiscence. These findings highlight the effect of the dehiscence size on conductive hearing loss in SSCD and contribute to a better understanding of the symptomatology of patients with SSCD.</p>
