Cochlear implantation in children with inner ear malformations: report of two cases.

UNLABELLED: Cochlear implantation of congenitally deaf children with inner ear malformations is gaining special interest. Although the number of the reported cases is increasing, the decision for implantation needs thorough investigation. Preoperative evaluation, surgical approach and postoperative follow-up can be challenging. STUDY DESIGN: A retrospective analysis of two cases with inner ear malformations. PATIENTS: One patient was a 3-year-old-girl who had cochlear and cochleovestibular nerve aplasia on the left side and incomplete partition on the other side. The other patient was a 5-year-old-boy who had hypoplastic cochlea on both sides. Both of them also had vestibular anomalies. Cases were implanted by using multichannel cochlear implant. RESULTS: No complications were encountered. Both patients responded to acoustic stimuli, and their speech perception skills were improved. After 10 months of cochlear implant use, their results seem encouraging. CONCLUSION: Except cochlear or cochleovestibular nerve agenesis, inner ear malformations cannot be accepted as a contraindication for cochlear implantation. Although there can be difficulties during the surgery or in the postoperative period, patients with inner ear malformations can also benefit from cochlear implantation. It is essential that all possible complications and postoperative performance should be discussed with the parents.

Cold dissection versus bipolar cauterizing tonsillectomy for bacteriemia.

OBJECTIVE: The purpose of this study is to compare transient bacteriemia ratios between cold dissection tonsillectomy and bipolar cauterizing tonsillectomy, and also to analyze the bacteria detected with superficial/central tonsillar cultures. METHODS: A total of 86 patients that were grouped as 46 patients of cold dissection tonsillectomy and 40 patients of bipolar cauterizing tonsillectomy were included in this study. Preoperative surface swab cultures, intraoperative central swab cultures of tonsils, and preoperative and postoperative blood culture samples were obtained. Antibiotic sensitivity tests were determined. Fischer exact chi 2 test was performed to compare the results of postoperative bacteriemia of both techniques statistically. RESULTS: Postoperative bacteriemia was detected in 6 (13%) patients of cold dissection tonsillectomy group. In 5 (83.3%) of the 6 postoperative bacteriemia patients of cold dissection tonsillectomy group, isolated microorganism was confirmed both in the blood cultures and in the central swab cultures of tonsils, and resistance to penicillin was established. No patient of bipolar cauterizing tonsillectomy group appeared with postoperative bacteriemia. There was a statistically significant difference (P=.028) for postoperative bacteriemia between cold dissection tonsillectomy group and bipolar cauterizing tonsillectomy group. CONCLUSION: We recommend bipolar cauterizing tonsillectomy for high-risk patients.

Preventive therapy for postoperative purulent otorrhea after ventilation tube insertion.

OBJECTIVE: Treatment modalities which are intraoperative irrigation of the middle ear with isotonic saline, postoperative oral antibiotic treatment, and postoperative topical antibiotic use have been compared with each other and with control group regarding their efficiency in preventing postoperative purulent otorrhea after ventilation tube insertion. Moreover, the costs of the treatment modalities were analyzed. STUDY DESIGN: Each group consisted of 70 patients, and a total of 280 patients were followed up for purulent otorrhea 2 weeks after the surgery. The study was a single-blind randomized clinical trial. RESULTS: Ten (14.28%) patients in the oral antibiotic group, 11 (15.71%) patients in the isotonic saline irrigation group, 6 (8.57%) patients in the topical antibiotic drops group, and 21 (30%) patients in the control group had postoperative purulent otorrhea. Statistical analysis determined a significant difference between each treatment modalities and control group but did not show any significant difference between the treatment groups. When the treatment options were compared according to their cost, however, the cost per successfully treated patient was significantly lower in the saline irrigation group. CONCLUSION: Intraoperative saline irrigation of the middle ear provides an effective, easy, and cheap treatment in preventing postoperative purulent otorrhea.

Early effect of exogenous Na hyaluronate on mucociliary clearance.

BACKGROUND: An animal study is performed to determine the early effect of 1% Na hyaluronate on mucociliary clearance function. METHODS: One percent of Na hyaluronate was introduced into the maxillary sinuses of rabbits by anterior antrostomy. A physiological solution of 1% NaCl was introduced into the maxillary sinuses of a control group to equalize the influence of Na for both groups. The treatment material was sprayed with an atomizer for coating the maxillary sinus lining. Technetium-99m diethylenetriamine pentaacetate dynamic scintigraphic imaging was performed to evaluate mucociliary clearance function on all rabbits 72 hours after the surgical procedure. RESULTS: Although the mean rate of mucociliary clearance of the Na hyaluronate group was slightly worse than the control group; there was no statistically significant difference between them. CONCLUSION: There is no early effect of exogenous 1% Na hyaluronate on mucociliary clearance function.
