Adverse skin reactions following percutaneous bone conduction implant surgery using the linear incision technique with and without subcutaneous tissue reduction.

CONCLUSIONS: Adverse skin reactions were equally distributed among age groups, surgical technique, or presence of a retroauricular incision. Implant loss was observed more frequently in children when compared to adults and elderly. OBJECTIVE: A bone conduction (osseointegrated) implant can be used for rehabilitation of patients with conductive hearing loss or single-sided deafness. The surgical technique has been modified to minimize adverse skin reactions and other complications. Two commonly used techniques are the linear incision technique with subcutaneous tissue reduction and the technique without tissue reduction. The primary aim is to compare the complication rate between the two surgical techniques. METHODS: Retrospective study on all bone conduction implant cases implanted between April 1990 and July 2014 at a tertiary referral center. Skin reactions were graded by Holgers' scale (grade 0-1: 'normal', grade 2-3: 'adverse'). The worst follow-up available was reported. RESULTS: Of the 289 bone conduction implants, 25 were implanted in children, 220 in adults, and 44 in elderly. Implant loss occurred in 2.8% of all cases: 8.0% in children, 2.3% in adults, and 2.3% in the elderly. Skin overgrowth was seen in 4.2%: 4% in children, 4.8% in adults, and 3.5% in the elderly. No differences were observed in the amount of adverse skin reactions (16.8% vs 14.7%) or skin overgrowth (4.6% vs 2.9%) between the surgical techniques. There was no difference in adverse skin reactions if the patient had a retroauricular incision (14.4% with vs 17.8% without prior incision).

Clinical need for a Baha trial in patients with single-sided sensorineural deafness. Analysis of a Baha database of 196 patients.

A bone-anchored hearing aid (Baha) is used in patients with single-sided sensorineural deafness (SSD) to overcome the head shadow effect. Of all the patients with SSD, treated at our hospital, 196 patients used a Baha on trial between November 2001 and April 2010. The objective of this study is to evaluate what factors determine the decision of a SSD patient whether or not to opt for a Baha device following a Baha trial period. 196 patients with SSD were enrolled for a trial period of 2 weeks at the Antwerp University Hospital, a tertiary referral centre. 93% of these patients suffered from an acquired hearing loss. 44% of all the patients (87/196) chose to wear a Baha device after the trail period, either on an abutment or on a headband. The collected data were analysed to determine correlations between the decision of a patient following a Baha trial period on the one hand, and Fletcher Index ipsi- and contralaterally, bone conduction hearing thresholds at the better hearing ear, aetiology, age at the start of the trial period, duration of hearing loss at the start of the trial period and the type of device used during the trial period, on the other hand. Although 66% of all the patients (109/196) declined the Baha after a trial, reasons not to choose a Baha were diverse and no crucial factors could be found that determine the success of a Baha trial period. Lack of improvement concerning speech understanding in noise was the most important reason mentioned by patients who declined the Baha. The authors advocate that all patients, suffering from SSD, should be offered the opportunity to try a Baha device as no factors could be found that determine the decision of a patient following the trial period.

Clinical practice: an approach to stridor in infants and children.

Stridor is the sound caused by abnormal air passage during breathing. The cause of stridor can be located anywhere in extrathoracic airway (nose, pharynx, larynx, and trachea) or the intrathoracic airway (tracheobronchial tree). Stridor may be acute (caused by inflammation/infection or foreign body inhalation) or chronic. It may be congenital or acquired. Stridor is a sign from which the underlying cause must be sought; it is not a diagnosis. The role of the pediatrician faced with a child or infant with noisy breathing is: (1) to determine the severity or respiratory compromise and the need for immediate intervention (to prevent respiratory failure); (2) to decide based upon history and clinical examination whether a significant lesion is suspected and, in the latter situation, to refer the child to an ENT surgeon for an upper and lower airway endoscopy; (3) to understand the consequences and management strategies of the underlying lesion and to collaborate with colleagues from related disciplines for follow-up and subsequent management of the child.

Prospective effectiveness of stapes surgery for otosclerosis in a multicenter audit setting: feasibility of the Common Otology Database as a benchmark database.

INTRODUCTION: The Common Otology Database (COD) is a joint effort by an international group of otologists to organize audit with a standardized reporting method in middle ear surgery. The first results on hearing outcome of the COD are presented in this article. OBJECTIVE: The primary objective was to confirm the validity of the benchmark group by comparing hearing outcome results with previously reported results. The secondary objective was to describe the population, technical aspects, and hearing outcomes of stapes surgery. STUDY DESIGN: Nonrandomized prospective multicenter audit. SETTING: Twenty tertiary-referral otologic centers. PATIENTS AND INTERVENTION: Primary and revision stapes operations in patients with otosclerosis. MAIN OUTCOME MEASURES: Air-bone gap (ABG), bone-conduction (BC) thresholds, and air-conduction (AC) thresholds were evaluated at 3 and 12 months according to the guidelines of the Committee on Hearing and Equilibrium for the evaluation of conductive hearing loss. Raw data were displayed in an Amsterdam Hearing Evaluation Plot. RESULTS: In primary stapes surgeries, the postoperative ABG was closed to 10 dB or less in 63.6% and to 20 dB or less in 92.6% (median, 8.75 dB). In revision stapes surgeries, the postoperative ABG was closed to 10 dB in 41.2% and to 20 dB in 76.5% of cases (median, 11.25 dB). The overall mean postoperative ABG at 12 months was 10.38 dB compared with 28.75 dB preoperatively. Using laser to perform the fenestration results in a less pronounced BC improvement when compared with procedures without laser assistance. No statistically significant difference in ABG pure-tone average at 3 months could be demonstrated between the different prosthesis types. CONCLUSION: Results of hearing outcome are similar to previous, primarily retrospective, single-center studies. Our data confirm the effectiveness of stapes surgery in patients with otosclerosis.
