Contemporary surgical issues in paediatric cochlear implantation.

OBJECTIVE: To review the contemporary surgical issues in paediatric cochlear implantation (CI) based on published evidence. DESIGN: Narrative literature review. RESULTS: Surgical challenges in paediatric CI are discussed, with respect to post meningitic labyrinthitis ossificans; cochlear malformation; cochlear implantation in infants; auditory neuropathy and cochlear nerve deficiency; bilateral cochlear implantation; hearing preservation; otitis media; and device failure. CONCLUSION: Early CI is recommended if bacterial meningitis causes profound sensorineural hearing loss (SNHL). CI in cochleovestibular malformation requires pre-operative imaging to plan surgical technique, choice of electrode, and to anticipate complication. Children with congenital severe to profound SNHL should undergo early bilateral simultaneous implantation, preferably before 12 months of age, except those with auditory neuropathy spectrum disorder who should be implanted after one year. Soft surgical technique should be deployed in an attempt to preserve any residual hearing. Otitis media with effusion is not a contraindication to cochlear implantation, but active or recurrent acute otitis media requires resolution of infection with grommet insertion pre-operatively. Device failure in CI recipients requires a stepwise audiological, medical, radiological, and device integrity assessment to determine the need for reimplantation.

High ear-piercing: an increasingly popular procedure with serious complications. Is good clinical practice exercised?

This study aimed to explore the current practice of performing high ear-piercing regarding consent protocols, and methods of practice using questionnaire-based survey in Hertfordshire and North London. Recommendations for good clinical practice are also made. 100 establishments performing ear piercing were identified. A 16-item questionnaire on techniques used, methods of high-ear piercing, methods of sterilization, consent issues and aftercare was completed. Seventy-six establishments agreed to participate. All practitioners prepared the skin before piercing. 58 (76%) used a needle for piercing, 11 (15%) used a spring-loaded gun and seven (9%) used both. 97% of the practitioners obtained written consent before proceeding. 9 (12%) had a lower age limit of 16 years and three (4%) of 18 years. 27 piercers (36%) provided an aftercare leaflet, 41 (54%) warned the patients about risks of infection, 16 (21%) warned about cosmetic deformity and 1 (1%) specifically mentioned cauliflower ear. Results indicated that high ear piercing is an invasive procedure with a significant risk of complications leading to cosmetic deformity. Establishments should be required to counsel patients properly about the risks and potential complications of the procedure. A code of practice should be drawn up with a minimum age for piercing, requirement for proper consent, excellent hygiene and good information for postoperative care.

Effect of cochlear implantation on middle ear function: A three-month prospective study.

OBJECTIVES/HYPOTHESIS: To determine if cochlear implantation has a delayed effect on the middle ear conductive hearing mechanism by measuring laser Doppler vibrometry (LDV) of the tympanic membrane (TM) in both implanted and contralateral control ears preoperatively and 3 months postoperatively, and then comparing the relative change in LDV outcome measures between implanted and control ears. STUDY DESIGN: Prospective cohort study. METHODS: Eleven preoperative adult unilateral cochlear implant recipients in previously unoperated ears with normal anatomy and aerated temporal bones were included in this study. The magnitude and phase angle of umbo velocity transfer function in response to air- conduction (AC) stimulus, and the magnitude of umbo velocity in response to bone- conduction (BC) stimulus were measured in the implant ear and the contralateral control ear preoperatively and 3 months postoperatively and compared. RESULTS: No significant changes in the magnitude or phase angle of TM velocity in response to either AC or BC stimulus were observed in the implanted ear relative to the contralateral control ear 3 months following cochlear implantation. CONCLUSIONS: From the results of LDV measurements, it can be said that cochlear implantation has no significant delayed effect on the middle ear conductive mechanism. LEVEL OF EVIDENCE: 4.

Aspirin does not prevent growth of vestibular schwannomas: A case-control study.

OBJECTIVES/HYPOTHESIS: To determine if aspirin intake is associated with reduced growth of vestibular schwannomas (VS). To determine the prevalence of contraindications to regular aspirin in patients with VS. STUDY DESIGN: Retrospective, observational case-control study. METHODS: The study utilized a postal questionnaire and telephone interviews to determine aspirin exposure. Propensity score matching was used to control for age, sex, and tumor size. Cases were defined as patients with VS proven to have grown on serial magnetic resonance imaging (MRI). Controls were defined as patient with VS stable on serial MRI. Prevalence of regular aspirin use was compared in patients with growing VS versus stable VS. Absolute and relative contraindications to aspirin intake were recorded. RESULTS: Six hundred fifty-three patients with VS were contacted, and responses were received by 67% (220 cases and 217 controls). The mean tumor size was 11.3 mm (9.0 mm and 13.3 mm in controls and cases, respectively). Aspirin exposure was more common in stable VS than growing VS (22.1% vs. 17.3%). However, following matching to control for covariates, aspirin was not found to be associated with VS stability (P = .475). Multiple logistic regression (analysis of variance) found tumor size to be the only factor strongly associated with tumor growth (P < .0001). Ninety-two percent of patients were able to take aspirin, with the majority being at low risk of complications from regular use. CONCLUSIONS: This study aimed to examine the relationship between aspirin intake and VS stability. In contrast to previous reports, after controlling for covariates, the findings do not demonstrate an association. Only tumor size at diagnosis appears predictive of risk of VS growth. LEVEL OF EVIDENCE: 3b. Laryngoscope, 128:2139-2144, 2018.

Cervicomastoidfacial versus modified facelift incision for parotid surgery: a patient feedback comparison.

INTRODUCTION: Traditionally, the cervicomastoidfacial (CMF) incision is used to excise benign tumours of the parotid gland. The rhytidectomy or modified facelift (MF) incision allows an alternative approach which leaves no visible neck scar. The objective of this study was to establish the frequency of each surgical approach used and identify any difference in complication and patient satisfaction between the two incisions for benign conditions of the parotid gland. PATIENTS AND METHODS: A retrospective analysis of 101 case notes for patients who underwent parotidectomy by both ENT and maxillofacial departments between January 2006 and February 2008 was undertaken. All histologically confirmed cases of malignancy were excluded. For each incision, immediate postoperative complications were obtained from the notes. A postal patient outcome evaluation questionnaire sought information regarding persistent and late complications as well as a visual analogue scar satisfaction score for both incisions. RESULTS: Overall, 79 parotidectomies were included (59 CMF incisions, 20 MF incisions). Of CMF incisions, 34% suffered facial weakness immediately postoperatively versus 20% of MF incisions. Of CMF incisions, 4% suffered postoperative haematomas versus none following MF incisions. In the study cohort, 47 (60%) responded to the postal feedback questionnaire (33 CMF versus 14 MF respondents). Information regarding immediate and late postoperative ipsilateral facial paraesthesia and gustatory sweating was obtained. Mean visual analogue scar satisfaction scores were 9.4 for CMF incisions and 8.9 for MF incisions. CONCLUSIONS: Immediate and late complications for CMF and MF approaches for benign disease parotidectomy were comparable, but scar satisfaction following MF incision was not greater than CMF incisions.

A third branchial pouch cyst presenting as stridor in a child.

We present a rare case of a third branchial pouch cyst in an 18-month-old child, presenting with stridor and a lateral cervical cystic mass. Differences in the anatomical course of third and fourth branchial cysts, and histological differences between branchial pouch and branchial cleft cysts are discussed.
