Wait and Scan Management of Intra-canalicular Vestibular Schwannomas: Analysis of Growth and Hearing Outcome.

OBJECTIVE: To report on the results of intracanalicular vestibular schwannomas (ICVS) that were managed by wait and scan and to analyze the possible predictors of tumor growth and hearing deterioration throughout the observation period. STUDY DESIGN: A retrospective case series. SETTING: Quaternary referral center for skull base pathologies. PATIENTS: Patients with sporadic ICVS managed by wait and scan. INTERVENTION: Serial resonance imaging (MRI) with size measurement and serial audiological evaluation. MAIN OUTCOME MEASURE: Tumor growth defined as 2 mm increase of maximal tumor diameter, further treatment, and hearing preservation either maintain initial modified Sanna hearing class, or maintain initial serviceable hearing (class A/B). RESULTS: 339 patients were enrolled. The mean follow-up was 36.5±31.7 months with a median of 24 months. Tumor growth occurred in 141 patients (40.6%) either as slow growth (SG) in 26.3% of cases or fast growth (FG) in 15.3% of cases. Intervention was performed in only 64 cases (18.8%). Out of 271 patients who underwent hearing analysis, 86 patients (33.5%) showed hearing deterioration to a lower hearing class of the modified Sanna classification. Tumor growth and older age were predictors of hearing deterioration. Of the 125 cases with initial serviceable hearing (Class A/B), 91 cases (72.8%) maintained serviceable hearing at last follow-up. Tumor growth and a worse initial pure tone average (PTA) were predictors of hearing deterioration. CONCLUSIONS: Wait and scan management of ICVS is a viable option and only 18.8% of patients needed further treatment. Hearing tends to deteriorate over time.

Simultaneous Cochlear Implantation After Translabyrinthine Vestibular Schwannoma Resection: A Report of 41 Cases.

OBJECTIVE: To study the auditory outcome of simultaneous translabyrinthine vestibular schwannoma (VS) resection and cochlear implantation (CI) after successful cochlear nerve preservation. STUDY DESIGN: A retrospective case series and patient questionnaire. SETTING: Quaternary referral center for skull base pathologies. PATIENTS: Patients with small (<2 cm) sporadic or neurofibromatosis 2 related tumors were included in this study. INTERVENTION: Vestibular schwannoma resection + simultaneous cochlear implantation. MAIN OUTCOME MEASURE: Audiological performance postimplantation and perceived patients' benefits. RESULTS: Forty-one patients were included. Thirty-three were sporadic VS and eight were neurofibromatosis 2. Auditory perception postimplantation was achieved in 33 patients (80.5%). At the last follow-up, 20 patients (48.8%) were users and 21 (51.2%) were nonusers. In the users' group, and after 1 year of implant activation, vowel identification was 75.3%, disyllabic word recognition 54%, sentence recognition 60.7%, and common phrase comprehension 61%, whereas in the nonusers' group and after 1 year of implant activation, vowel identification was 22.9%, disyllabic word recognition 14.8%, sentence recognition 15.3%, and common phrase comprehension 14%. Sixteen users were classified into 10 high performers, three intermediate performers, and three poor performers. In the user' group, the mean postimplantation pure tone average was 63.4 dB and the mean speech discrimination score was 63.7%. CONCLUSIONS: Simultaneous CI and VS resection is a viable option with many patients achieving auditory perception and nearly half the patients are CI users at long follow-up.

Does the involvement of first-year residents have a negative impact on the performance of a newborn hearing screening program?

OBJECTIVES: We aimed to evaluate the efficiency of our hearing screening program, prior to hospital discharge, together with the consistency of our teamwork including first year residents by assessing a learning curve for the operators involved. METHODS: We evaluated all the data collected during the first stage of the screening program of all non-NICU neonates from March 2009 to July 2013, analyzing by means of a linear regression model, the monthly referral rate for the whole period of activity of each group of residents. RESULTS: performances of each group of screeners were statistically different (chi square test p < 0.005). The nptrend test showed that group 2 (p = 0.01) and group 4 (p = 0.01) reached a statistical significance in higher and lower referral rates respectively. No statistical differences were found in other groups (Group 1 p = 0.161; Group 3 p = 0.853). CONCLUSION: Despite a statistically significant difference in the performances between the groups of residents, the referral rates for each group (range 6.18%-9.29%) and the overall referral rate for the whole period (7.84%) agree with the values commonly reported for TEOAEs in the literature. It means that our screening program is reasonably effective despite a yearly turnover of operators.

Medical-surgical management and clinical outcome in cervical abscesses.

INTRODUCTION: This study aims at defining through a retrospective evaluation, the clinical parameters affecting the clinical course and consequently the management of patients presenting with cervicofacial abscesses. METHODOLOGY: A total of 394 patients diagnosed with abscess at the University of Sassari Otorhinolaryngology Division between 2009 and 2017 were included; among these, eleven patients were diagnosed with necrotizing fasciitis. Personal and clinical parameters including the LRINEC score and the medical and/or surgical treatment used were analyzed for each patient. The most frequently affected site was the peritonsillar space (76.9%), followed by the parapharyngeal space. RESULTS: Mean age was 41(±17) years, the male population was slightly overrepresented (68%). An average of 6 (±7) days of hospitalization duration was recorded. The mortality rate was confirmed to be relatively low (1/349 patients) and was reported only in one patient diagnosed with necrotizing fasciitis (1/11). CONCLUSION: Diagnosis, correct clinical definition and early medical-surgical treatment of neck abscesses were crucial to reduce complications; LRNEC score, C-reactive protein, glycemia and creatininemia proved to be reliable prognostic indicators of difficult patient management and risk of complications.

HDR interventional radiotherapy (brachytherapy) in the treatment of primary and recurrent head and neck malignancies.

BACKGROUND: Interventional radiotherapy (brachytherapy; IRT) reemerged in the last decades as a potentially useful tool in head and neck oncology after a set of clear technical improvements were developed. METHODS: Sixty-one high dose ratio (HDR) IRT treatments were recommended and performed on 58 patients. We classified the cases into four relatively homogeneous groups based on the clinical needs that led to the recommended IRT. Also, we separately evaluated primary and recurrent cases. RESULTS: Disease-specific survival was significantly different among the four treatment groups. The group with the best prognosis was the cohort treated locally by exclusive interstitial IRT for resectable midface malignancies (2-year relapse-free survival = 82%, disease-specific survival = 89%). CONCLUSION: HDR IRT is a valuable tool in well-defined clinical situations and, in particular, in recurrences. In midface malignancies, it could become the preferred primary treatment.
