Submersion with grommets: contamination is possible at minimal depth, as demonstrated with a novel middle-ear model.

OBJECTIVE: Advice to patients following grommet insertion and waterproofing can vary from clinician to clinician. A laboratory based experiment was performed to determine at what depth water contamination would occur through various grommet tubes. METHODS: A novel experimental ear model was developed using an artificial tympanic membrane and ventilation tubes. Water contamination was identified using an effervescent solid that reacts when in contact with water. Measures of dispersion were used to describe the results. RESULTS: The average depth of water contamination was: 19.64 mm (range = 11-33 mm, standard deviation = 5.55 mm) using a Shepard grommet; 20.84 mm (range = 18-26 mm, standard deviation = 1.97 mm) with a titanium grommet; and 21.36 mm (range = 18-33 mm, standard deviation = 3.03 mm) using a T-tube. Water contamination was possible at depths of 11-33 mm. The average pressure at water effervescent activation was 0.20 kPa. CONCLUSION: Submersion underwater at any depth with grommets is likely to lead to middle-ear contamination. These findings are concordant with clinical studies.

Revision cochlear implantation: The Irish experience.

Objectives: To report a long-term experience on revision cochlear implantation (RCI) in a single institution, categorize their indications and to identify predictive parameters of implant failure. Methods: A retrospective study was conducted on a prospective database of a national cochlear implant unit. Patients requiring RCI between January 1995 and June 2016 were identified and stratified into adult and paediatric group. Medical records, investigation reports and device analysis reports were reviewed and analysed. Results/Discussion: A total of 37 children and 21 adults were identified requiring RCI on 60 devices. 63.3% of the RCI was indicated due to the device failure, while 36.7% was due to various medical reasons. Higher device failure rate was reported in the paediatric group, due to the high number of direct head trauma, which was not observed in the adult group. The leading medical indication for RCI was due to wound infection (10%). The overall RCI rate was 5.0%, among which 3.1% was due to device failures. A brief discussion on various medical indications, surgical challenges, and the mechanism of thought process to consider RCI, including treatment planning was outlined. Conclusion: RCI in the paediatric population poses a unique challenge. Integrity testing is helpful in identifying a potential device malfunction; however, regular clinical follow-up with multidisciplinary assessments is invaluable in the decision process for RCI.

Pierre Robin sequence: an institutional experience in the multidisciplinary management of airway, feeding and serous otitis media challenges.

OBJECTIVES: To evaluate the course and prognosis of airway obstruction, feeding difficulties and hearing abnormalities in patients with Pierre Robin sequence (PRS). METHODS: A retrospective review was conducted, of 69 patients with PRS, attending between 1991 and 2010 at the Children's University Hospital in Dublin. Data regarding airway management, nutritional status and hearing difficulties was collected prospectively. RESULTS: Airway obstruction requiring intervention other than positional therapy was seen in 39% (27) patients. Fifty nine percent (16/27) of these patients, who failed positional therapy, were successfully managed with a nasopharyngeal airway. Following failed intervention with nasopharyngeal airways, two patients had airway maintenance achieved with a successful glossopexy procedure. One patient had an adequate airway achieved with nasal continuous positive airway pressure. Eight patients (12%) required a surgical tracheostomy. Of those who required a tracheostomy, six patients had isolated PRS, one patient had PRS in association with Stickler syndrome and one patient had Nager acro-facial dystosis. Duration of tracheostomy tube ranged from 10 to 19 months, mean 13 months. Seventy percent (48 patients) required supplementary feeding in the form of nasogastric (NG) or gastrostomy tube. Forty-four patients were successfully managed with a temporary NG tube. One patient required a prolonged NG tube, and three required a gastrostomy tube. Twenty-one (30%) patients were successfully managed with a specialised Haberman bottle. Twenty-four patients (35%) who had their airway managed successfully by positional therapy, still required supplemental feeding. Thirty-one patients (45%) demonstrated a conductive hearing loss at some stage, which affected their speech and language development. Twenty-four patients (35%) required tympanostomy tube insertion once, while 7 (10%) of patients required ventilation tube insertion twice or more. CONCLUSION: Airway management in the majority of PRS can be successfully achieved by conservative methods. Even in the presence of an adequate airway, many patients will require supplemental feeding. Early audiological assessment is necessary as many patients will need tympanostomy tube placement to ensure adequate speech and language development.

Prospective double blind randomized clinical trial comparing 75% versus 95% silver nitrate cauterization in the management of idiopathic childhood epistaxis.

PRIMARY OUTCOME MEASURE: to evaluate which concentration of silver nitrate cauterization was more efficacious in the management of idiopathic childhood epistaxis. SECONDARY OUTCOME MEASURES: to evaluate side effects and pain scores of the differing concentrations. STUDY DESIGN: Prospective double blind randomized clinical trial. PARTICIPANTS AND SETTING: All children 16 years of age or younger referred by the accident and emergency department or general practitioner, with recurrent idiopathic epistaxis, who met the inclusion criteria entered the trial. Patients were randomized to receive either the 75% or 95% silver nitrate cauterization. Patients were reviewed at two weeks and eight weeks post cauterization. Pain scores, side effects and success of each treatments were recorded at the follow up clinic. RESULTS: 101 patients completed the trial. 52 patients were randomized to receive the 95% concentration, and 49 patients were randomized to receive the 75% cauterization. In the 75% concentration group, 98% of patients had total resolution of their symptoms at the eight-week follow up. Mean pain scores in this group was 1 out of 10. In the 95% group, 90% had total resolution of their symptoms at the eight-week follow up. Mean pain scores in this group was 5 out of 10. There was a statistical difference in efficacy and pain scores (0.01 and 0.001). CONCLUSION: We would recommend the use of 75% silver nitrate cauterization in the management of childhood epistaxis, it appears to be more efficacious, has fewer side effects and is better tolerated.

Autologous bone pate in middle ear and mastoid reconstruction.

OBJECTIVE: To review outcomes of middle ear and mastoid surgery where autologous bone pate was used. DESIGN: Retrospective review of 42 consecutive patients who underwent middle ear and mastoid reconstruction using autologous bone pate by the senior author over a three year period. PARTICIPANTS: Patients underwent surgery for a spectrum of disease from chronic suppurative otitis media, to extensive cholesteatoma with intracranial abscess formation. RESULTS: Autologous bone pate was used in conjunction with an anteriorly based musculo-fascial flap via a layered technique using tragal cartilage and temporalis fascia, to obliterate cavities in all patients. To date, there has been no evidence of recurrence or otorrhea in the cohort. Shallow retraction has been observed in 6.8%. CONCLUSION: We advocate that bone pate, when used in conjunction with a middle temporal artery flap and layers of tragal cartilage and fascia, is a safe, effective treatment for problematic middle ear disease.

Complementary medicine use in patients with head and neck cancer in Ireland.

The objectives of the study were: first, to determine the prevalence of traditional medicine (TM) and complementary and alternative medicine (CAM) use in head and neck cancer patients in Ireland; second, to educate ourselves on the plethora of CAM/TM options available to patients outside the dominion of conventional medicine. The study design consisted of a cross-sectional survey carried out in three head and neck cancer centres. Self-administered questionnaires were distributed to 110 head and neck cancer patients attending the three cancer centres and data were collected for statistical analysis. A total of 106 patients completed the questionnaire; 21.7% of the participants used CAM/TM since their diagnosis with head and neck cancer. CAM/TM usage was higher in female (34.3%) than in male patients (16.2%). CAM/TM use was more common in the 41-50-year age group, in patients with higher educational levels and those holding strong religious beliefs, and also in married than single patients. The most common types of CAM/TM used were spiritual and laying on of hands. The most common reasons reported for using CAM/TM were to counteract the ill effects of treatment and increase the body's ability to fight cancer. Sources of information on CAM/TM were friends (65%), family (48%) and media (21%). This survey reveals a high prevalence of CAM/TM use in head and neck cancer patients, hence emphasising the need for otolaryngologists to educate themselves on the various therapies available to be able to provide informative advice. There is an urgent need for evidence-based investigation of various CAM/TM therapies currently offered to patients.

Acute mastoiditis in children: presentation and long term consequences.

UNLABELLED: Acute mastoiditis, a destructive bacterial infection of the mastoid bone and air cell system, is relatively uncommon today but remains a potentially serious condition. There is a lack of information in the literature regarding the long term otological problems that children may face following an episode of this condition. OBJECTIVES: Our aim was to examine the presentation, complications and hospital course in this patient population, and to ascertain whether these patients had long term otological problems. METHODS: We retrospectively reviewed the medical records of all patients presenting with acute mastoiditis between January 1990 and December 2005. Patients' parents were contacted by telephone and questioned about further otological problems. RESULTS: Twenty-nine patients were included in the study, and 27 of these patients' parents were contactable to complete the telephone questionnaire. Sixty-nine per cent of children had no previous history of acute otitis media prior to presentation. Forty-five per cent of patients had received oral antibiotics prior to presentation. Sixty-two per cent of patients developed complications, i.e. a subperiosteal abscess or failure to respond to medical therapy, resulting in the need for surgical intervention (in the form of incision and drainage of periosteal abscess, cortical mastoidectomy, or grommet insertion). Mean follow up of patients was eight years and one month; five (17 per cent) patients had been followed up for less than one year. Two (7 per cent) patients developed a further episode of mastoiditis within six weeks of initial presentation, both of whom required cortical mastoidectomy. Three (10 per cent) patients had further problems with recurrent acute otitis media, requiring tympanostomy tube insertion. One patient required a modified radical mastoidectomy for cholesteatoma (15 years later). Twenty-two patients (91 per cent) had been followed up for longer than one year; these patients had subjectively normal hearing and were asymptomatic at the time of study. CONCLUSION: The majority of patients who had suffered an episode of acute mastoiditis had no adverse long term otological sequelae.

Patient mobile telephone 'text' reminder: a novel way to reduce non-attendance at the ENT out-patient clinic.

BACKGROUND: Non-attendance at out-patient clinics is a seemingly intractable problem, estimated to cost 65 pounds sterling (97 euros) per incident. This results in under-utilisation of resources and prolonged waiting lists. In an effort to reduce out-patient clinic non-attendance, our ENT department, in conjunction with the information and communication technology department, instigated the use of a mobile telephone short message service ('text') reminder, to be sent out to each patient three days prior to their out-patient clinic appointment. OBJECTIVE: To audit non-attendance rates at ENT out-patient clinics following the introduction of a text reminder system. STUDY DESIGN: Retrospective review. METHODS: Non-attendance at our institution's ENT out-patient clinics was audited, following introduction of a text message reminder system in August 2003. Rates of non-attendance were compared for the text message reminder group and a historical control group. RESULTS: Before the introduction of the text message reminder system, the mean rate of non-attendance was 33.6 per cent. Following the introduction of the system, the mean rate of non-attendance reduced to 22 per cent. CONCLUSION: Sending text message reminders is a simple and cost-effective way to improve non-attendance at ENT out-patient clinics.

Parapharyngeal abscess in an insulin dependant diabetic patient following an elective tonsillectomy.

OBJECTIVES: To demonstrate a potentially life-threatening complication following tonsillectomy in a diabetic patient and discuss the possible pathogenesis. METHODS: Case report and review of the world literature concerning parapharyngeal abscess post-tonsillectomy. CASE REPORT: A 20-year-old female patient underwent an uneventful tonsillectomy following a history of recurrent tonsillitis. She re-presented 14 days post-surgery with a large erythematous tender right mid cervical neck swelling. Clinical and radiological evaluation confirmed a parapharyngeal abscess. She proceeded to have an incision and drainage of the abscess through a horizontal skin crease incision and subsequent intravenous antibiotic therapy. She was discharged home well three days post-surgery. CONCLUSION: Diabetes mellitus is a well-recognised systemic disease that may leave an individual more susceptible to infection. We report the first case in a young healthy diabetic patient and highlight a potential serious complication following a routine tonsillectomy.

Otogenic pneumocephalus: case report and review of the literature.

We report a case of a 70 year old lady who presented to the accident and emergency department with a three day history of left sided otalgia, drowsiness and confusion. On admission her temperature was 39 degrees C, glascow coma scale was 14/15 and otoscopy revealed a left sided otitis media. There was no sign of CSF otorrhoea or mastoiditis. Neuro-otological examination was normal. High resolution CT scan of temporal bones and brain showed evidence of pneumocephalus near the left cerebello-pontine angle and posterior to the left petrous bone. No focal parenchymal pathology, intra-cranial bleed or defect in the tegmen was noted. The patient responded very well to conservative management in the form of high dose intravenous antibiotics. We would like to emphasise that this complication of otitis media should be borne in mind when an elderly patient presents with otalgia and confusion.

Silver nitrate cauterisation, does concentration matter?

Epistaxis from the anterior septum is frequently treated with a topical application of silver nitrate. There are two concentrations commercially available and in use by otolaryngologists, these are 75% and 95% silver nitrate. The purpose of the present study was to investigate the histological effect of the two different silver nitrate concentrations on mucosal tissue at a fixed contact time of 5 s. Twelve children undergoing routine tonsillectomy were included in this study. Prominent blood vessels on the mucosal surface of the tonsils were identified and a single vessel on each tonsil was selected for application of either 75% or 95% concentration of silver nitrate for 5 s. Depth of penetration across the tonsil tissue was measured following application of the two different silver nitrate concentrations. This study demonstrated a significant difference in depth of tissue penetration with the 95% averaging a twofold increase in penetration depth. It is likely that the increased depth of penetration with 95% silver nitrate may increase the risk of complication of nasal cautery such as septal perforation, particularly in patients undergoing repeated or bilateral nasal cautery.

Does the addition of sublingual gland excision to submandibular duct relocation give better overall results in drooling control?

UNLABELLED: Submandibular duct relocation plus or minus excision of the sublingual glands are relatively simple procedures with low morbidity. Between 1981 and 2005, 71 submandibular duct relocation and 29 submandibular duct relocation plus excision of the sublingual glands procedures were conducted. OBJECTIVES: To compare both procedures including operative time, length of hospital stay, postoperative complications, drooling scores and parental satisfaction. STUDY DESIGN: Prospective study. SETTING: Paediatric tertiary referral centre. PARTICIPANTS: Patients referred with excessive drooling after failure of conservative methods. EXCLUSION CRITERIA: patients with recurrent aspiration pneumonias or dental caries. Two patients were lost to follow up and excluded from the study. RESULTS: Operative time and length of hospital stay were increased in the submandibular duct relocation plus sublingual gland excision group. Drooling scores and parental satisfaction results were excellent, 93% of parents in the submandibular duct relocation group and 89% of parents in the duct relocation plus sublingual glands excision were satisfied and would recommend the procedure. There was no statistical difference (P = 0.643) in drooling scores between the two procedures. Postoperative morbidity was higher with the addition of sublingual gland excision, with postoperative haemorrhage occurring in 13.7% and 36% of parents expressing concern over postoperative pain, compared with 3% postoperative haemorrhage rate with submandibular duct relocation and only 12% of parents expressing the same concerns. CONCLUSION: We conclude that both procedures are effective in drooling control, but the addition of sublingual gland excision increases morbidity and we are no longer excising these glands with submandibular duct relocation.

Incidence and prognostic influence of lymph node micrometastases in rectal cancer.

AIMS: The aim of this study was to determine the rate of lymph node micrometastases and evaluate their prognostic significance in rectal cancer. METHODS: Patients with either Dukes A or B rectal carcinoma who had undergone curative resection by either low anterior resection or abdominal perineal resection between 1991 and 2000 were selected from a prospectively collated database. None of the patients had metastasis at the time of surgery and none received adjuvant or neoadjuvant therapy. A single section from each lymph node was stained with haematoxylin and eosin (H+E) and with CAM 5.2 by immunohistochemistry. Statistical analyses were performed with Chi-square test. RESULTS: A total of 774 lymph nodes with a median of 14 lymph nodes per patient were examined, from a cohort of 56 patients with a median age of 66 years. In the 56 patients in whom lymph node metastases were not detected by haematoxylin-eosin staining, cytokeratin staining was positive in 15 lymph nodes from 10 patients. Nine patients had disease recurrence at a median follow-up of 98 months. The presence of lymph node micrometastases by immunohistochemistry did not predict either disease-free (p=0.44) or overall survival (p=0.63). CONCLUSION: Immunohistochemical staining detects micrometastases in rectal cancer which are not observed with H+E staining. However, no significant relationship was observed between disease relapse and rectal micrometastases detected by immunohistochemistry.

Successful ex utero intrapartum treatment (EXIT) procedure for congenital high airway obstruction syndrome (CHAOS) owing to a large oropharyngeal teratoma.

Large fetal neck masses can present a major challenge to securing an airway at birth, with associated risks of hypoxia, brain injury and death. The authors report a case of a giant oropharyngeal teratoma diagnosed in a fetus of 19 weeks gestation. The fetus was delivered by the ex utero intrapartum treatment procedure allowing sufficient time on placental support for bronchoscopy and tracheostomy to secure the airway. A multidisciplinary team approach combined with an accurate prenatal diagnosis obtained through fetal ultrasound was the key to a successful outcome. Unfortunately due to the large size of tumour and intracranial extension, the lesion was unresectable and the baby died 6 days after birth.

Neglected keratosis obturans causing facial nerve palsy.

Keratosis obturans is characterized by the accumulation of desquamated keratinous material in the bony portion of the external auditory canal. Classically, it is reported to present with severe otalgia, conductive hearing loss and global widening of the external auditory canal. Extensive erosion of the bony meatus, with exposure of the facial nerve, has been previously reported, but no case of facial nerve palsy has as yet been published. We report the first published case, to our knowledge, of a unilateral facial nerve palsy secondary to neglected keratosis obturans.

Routine nasopharyngeal biopsy in adults presenting with isolated serous otitis media: is it justified?

Nasopharyngeal malignancy accounts for less than 2 per cent of all head and neck cancers. Serous otitis media (SOM) causing deafness is a recognized indicator of nasopharyngeal obstruction and the possibility of a nasopharyngeal malignancy must be considered in all adults. Examination under anaesthesia (EUA) and biopsy of the nasopharynx is routinely undertaken in many centres to rule out nasopharyngeal malignancy in adults with SOM. The purpose of this 10-year retrospective study was to evaluate the case records of all adult cases of SOM, including their presentation, clinical findings, management and nasopharyngeal biopsy results. Eighty-five patients were included in the study. Fifty-nine presented with unilateral SOM and 26 with bilateral SOM. The primary presenting complaint in all cases was hearing loss. A nasopharyngeal mass was documented in 55 patients (69 per cent). Four nasopharyngeal masses were noted to have irregular or exophytic mucosa on flexible nasendoscopy. All patients underwent a EUA of the ears and a nasopharyngeal biopsy. The four patients with suspicious-looking masses were all found to have malignancies (two squamous cell carcinomas, one B-cell non-Hodgkin lymphoma and one adenocarcinoma). Three of these patients presented with unilateral SOM and one with bilateral SOM. All other patients with masses were found to have benign lymphoid hyperplasia. In total, 4.7 per cent of the adults with conductive hearing loss secondary to SOM were found to have a malignancy on nasopharyngeal biopsy. We would advocate a high index of suspicion of a nasopharyngeal tumour in adults presenting with SOM. If a mass is found in the nasopharynx then it should be biopsied. If no mass is found then it is not necessary to biopsy; however, close follow up, with repeat fibre-optic nasendoscopy, is advised.
