To discuss our management strategy of vestibular schwannoma in patients with neurofibromatosis type 2 (NF2). Retrospective study. Quaternary referral skull base center. Thirty-eight NF2 patients who had undergone 48 operations at the Gruppo Otologico between January 1988 and December 2008. The mean age at time of surgery was 36.3 years (range, 17-65 yr), and the average tumor size was 3.1 cm (range, 0.6-6 cm). There were 27 female and 21 male ears, and 25cases were right side ears, whereas 23 were left sided. The average follow-up time was 3.7 years. Surgical approaches, hearing, and facial nerve functions, as well as hearing rehabilitation and facial nerve reconstruction outcomes, are discussed. Total tumor resection was achieved in 44 cases (92%). Facial nerve function was postoperatively House-Brackmann grades I-III in 36 cases (77%); it was grade I in 17 cases (35%) and grade II in 8 cases (17%). In 7 cases, hearing preservation was attempted, and a measurable hearing has been recorded in 5 cases (71%). Auditory brainstem implant was inserted in 25 cases, and concomitant cochlear implants were inserted in 5 cases. Early diagnosis and treatment of bilateral vestibular schwannoma in patients with NF2 will achieve the best outcomes regarding facial nerve, hearing preservation, and postoperative complications. The watchful waiting policy will decrease the chance of reaching these goals. Cochlear implants and auditory brainstem implant have made hearing rehabilitation possible in NF2 patients who had bilateral sensorineural hearing loss.

Pulmonary hydatid cyst is a parasitic disease causing an endemic and a health burden in many regions. Lung cysts are more common than liver cysts in children and patients may remain asymptomatic. Cyst rupturing is not uncommon, and it is considered the most feared complication. In this cohort study, we aimed to identify the risk factors related to cyst rupture in a Jordanian pediatric population. We retrospectively evaluated all pediatric patients who underwent cystostomy and capitonnage for pulmonary hydatid cyst between 2003 and 2020 at King Abdullah University Hospital. We found 43 patients with a mean age of 13 ± 4 years who suffered from 61 pulmonary cysts. 55.6% of them were males. The most prevalent symptom was shortness of breath. The rupture rate for patients was 39.5%, and 29.5% for cysts. None of the patients with cyst rupture had an anaphylactic reaction. The left lower lobe was the most common location for both intact and ruptured cysts. 25.6% of the patients had giant cysts (>10 cm) with a mean of 7.4 cm for all cysts. Patients with intact cysts had higher-rates of cough (42.3% vs. 29.4%) and lower-rates of shortness of breath (34.6% vs. 52.9%) than patients with ruptured cysts, which were not statistically significant. Although statistically insignificant, patients with ruptured cysts tended to have multiple cysts in one lung (29.4% vs. 7.7%, p = 0.180), and more complication rates (29.4% vs 7.7%, p = 0.09). Both groups had almost identical IgG-ELISA positive results. We found no significant association between cyst rupture and age, gender, presenting symptoms, cyst size, cyst location, and rate of postoperative complications. The rupture of pulmonary hydatid cyst has clinical consequences in pediatric patients, further studies on larger populations are needed to identify factors that make patients more prone to rupture and prioritize them for clinical monitoring and management.

Objective: To evaluate the influence of different piston variables on hearing following stapedotomy.Methods: Data were analysed in groups according to: piston material (titanium vs fluoroplastic), shaft diameter (0.4 mm vs 0.5 mm) and crimping style (manual crimping vs self-crimping). Pre- and post-operative average air–bone gap, air–bone gap difference, success rate and operative time were evaluated.Results and conclusion: Fifty-one patients (58 ears) were included. A post-operative air–bone gap of 10 dB or lower was achieved in 44 cases, with a success rate of 75.9 per cent; 52 cases (89.7 per cent) had an air–bone gap of 20 dB or lower. The success rate was higher, but not significantly, in fluoroplastic than in titanium pistons (85 per cent vs 70 per cent). Pistons with shaft diameters of 0.5 mm and 0.4 mm had success rates of 79 per cent and 72 per cent, respectively. No significant differences were found for any audiometric parameters. There were no significant differences between manual crimping and self-crimping pistons in terms of audiometric results or success rate.

Objective: This literature review analysed facial nerve management strategies in jugular paraganglioma surgery and discusses the tumour resection rate and the facial nerve outcome associated with each technique.Methods: A retrospective review of PubMed and Medline articles on the surgical treatments for jugular paraganglioma was performed. Tumour resection rates and post-operative facial nerve function after non-rerouting, short anterior rerouting and long anterior rerouting approaches were evaluated for each article.Results: A total of 15 studies involving a total of 688 patients were included. Post-operative facial nerve function was similar after non-rerouting and short anterior rerouting approaches (p= 0.169); however, both of these techniques had significantly better post-operative facial nerve outcomes compared with long anterior rerouting (p< 0.001 andp= 0.001, respectively). The total tumour removal rate was significantly higher for long anterior rerouting than with the non-rerouting approach (p= 0.016). There was no difference in total tumour removal rate between the long and short anterior rerouting approaches (p= 0.067) and between the short anterior rerouting and non-rerouting approaches (p= 0.867).Conclusion: No strict guidelines for facial nerve management in jugular paraganglioma resection are available. Although long anterior rerouting provides the best tumour exposure along with a low morbidity rate, case-by-case selection of the surgical approach is recommended.
