Abstract
CONCLUSION: Data obtained from a cohort of 10 post-lingually deaf adult patients indicated that use of a higher stimulation rate, in the setting of the main peak interleaved sampling (MPIS) strategy coupled with the Neurelec-MXM Digisonic SP cochlear implant system, gives a significant advantage in terms of speech perception if compared with a lower rate, especially in a noisy environment.
OBJECTIVES: To evaluate speech recognition performances in post-lingually deaf adult cochlear implant recipients using two different stimulation rates (260 pps/e and 600 pps/e) in the setting of the MPIS strategy combined with the MXM-Neurelec Digisonic SP cochlear implant system.
PATIENTS AND METHODS: Ten post-lingually deaf adults who consecutively received a Neurelec-MXM Digisonic SP device at the CI Center of the University of Parma participated in the study. The study was conducted prospectively as a within-subject repeated measures (ABA protocol) between January 2007 and January 2008. Each subject was exposed to and sequentially tested with two different rates of stimulation (260 pps/e and 600 pps/e), in quiet and in a noisy environment. Statistical analysis was performed on the data obtained.
RESULTS: Subjects using the MPIS strategy with a stimulation rate of 600 pps/e performed significantly better in words and phrases recognition tests in both a noisy and a quiet environment

Abstract
OBJECTIVES/HYPOTHESIS: Patients infected with HIV have an increased risk of developing sensorineural hearing loss (SNHL), yet pathogenesis of SNHL in HIV infection is still poorly understood. In subjects affected by bilateral profound or total SNHL, cochlear implantation may be the only possibility to restore a hearing level that allows them to have an acceptable quality of life.
STUDY DESIGN: Case report.
METHODS: A retrospective chart review of a HIV type 1-seropositive profoundly deafened patient who underwent cochlear implantation.
RESULTS: To date, with a follow-up of 4 years, the patient has not experienced any complication and has regained useful open-set speech perception.
CONCLUSIONS: Cochlear impairment with preserved auditory pathways can be responsible for profound SNHL in HIV-infected patients. Cochlear implantation can restore a social hearing in these patients, dramatically improving their quality of life. The surgical procedure can be safely performed when keeping in mind that the general condition of the patient is the decisive factor for or against surgery

Abstract
The objective was to evaluate the long-term clinical outcome of the bony outer attic wall reconstruction (scutumplasty) by using autogenous bone paté in a series of patients who underwent canal wall up (CWU) mastoidectomy for middle ear cholesteatoma. In addition, an histological analysis of bone paté graft specimens taken during the second-look procedure 12 months after the first surgery, was carried out. A series of 134 ears from 128 patients with cholesteatoma who underwent staged CWU mastoidectomy and attic reconstruction with bone paté, between 1995 and 2000 inclusive, was retrospectively analyzed. In ten randomly selected ears, biopsies from the newly built outer attic wall were taken during the second-look operation and were microscopically analyzed. At the second stage operation, the bone paté graft was found normal in 64.9% of cases. In 39 (29.1%) patients there was a remarkable hypertrophy of the bone paté which was subsequently thinned out by using a diamond burr. A partial resorption of the bone paté was observed in 4.4% of ears and a total resorption in 1.4%. Residual cholesteatoma was found in 13.4% of ears. At the last follow-up visit, recurrent cholesteatoma was observed in 5.2% of ears. Self cleaning attic retraction pocket occurred in 4.4% of ears. Twelve months after implantation, histologic examination on the newly built bone showed a well-structured bony tissue. In particular, osteoblasts lined bone trabeculae with signs of an active tissue remodeling. In conclusion, the reconstruction of the outer attic wall should be considered a fundamental step when performing a CWU procedure in order to prevent attic retractions and recurrences of cholesteatoma. In our experience, autogenous bone paté graft has demonstrated good long-term results in outer attic wall reconstruction being adaptable, well tolerated, stable and of low cost

Abstract
OBJECTIVES: The aim of this study is to assess the post-implantation speech perception and intelligibility of speech produced by five profoundly deaf children with cerebral palsy.
METHODS: This study is derived by a review of a prospectively maintained data collection on all patients entering the cochlear implant program. Five children with cerebral palsy who underwent cochlear implantation participated in this study. Functional outcome was assessed using the Speech Perception Categories and the Speech Intelligibility Rating scale. The follow-up of the series ranged from 12 to 45 months.
RESULTS: At the last follow-up, two children who were placed into speech perception category 1 (detection of a speech signal) preoperatively progressed to category 6 (open-set word recognition with familiar words) postoperatively. Two children moved from preoperative category 2 (pattern perception) to postoperative category 6. One child placed into category 0 (no detection of speech) preoperatively progressed to category 4 (word identification) postoperatively. Before implantation, three children had connected speech unintelligible, and two subjects had connected speech intelligible to a listener who concentrates and lip-reads. At the last follow-up, one child had connected speech unintelligible, two children had connected speech intelligible to a listener who concentrate and lip-reads, one child had connected speech intelligible to a listener who has little experience of a deaf person's speech, and one child had connected speech intelligible to all listeners.
CONCLUSIONS: Cochlear implantation allowed these patients to dramatically improve their quality of life, increasing their self-confidence, independence and social integration

Abstract
OBJECTIVE: The objectives of this study were to evaluate outcomes from facial nerve (FN) cable grafting in patients who experienced FN transection during vestibular schwannoma removal and to compare the FN outcomes of patients who underwent FN grafting by using fibrin glue with those of patients who underwent FN grafting by using microsuture.
MATERIAL AND METHODS: We retrospectively evaluated a series of 33 patients in whom FN grafting was achieved either by using microsuture (8 cases) or fibrin glue (25 cases). Immediate repair of the FN was performed in all cases at the time of initial resection. The patients FN function was assessed preoperatively, in the immediate postoperative period, and at 3, 6, 9, and 12 months or more postoperatively using the House-Brackmann grading system. All patients had at least 1-year follow-up.
RESULTS: At 12 months, a House-Brackmann grade III was achieved in 75% of those who underwent cable nerve graft interposition by using microsuture and in 76% of those who underwent cable nerve graft interposition by using fibrin glue. Analysis of final FN function outcomes demonstrated no statistically significant difference in FN outcomes between the 2 groups (P = .891, Mann-Whitney U test; P = .1, Fisher exact test).
CONCLUSIONS: The functional results after FN cable grafting by using fibrin glue exclusively were equivalent to those obtained with microsuture. However, the technique of FN repair by means of fibrin glue is technically simple, less time-consuming, and imparts less trauma on the nerve than does the traditional suture method
