Summary: Nomograms developed in this study accurately predicted hearing outcomes in patients with NF2, with large tumor size and duration of symptoms being independent risk factors for preoperative useful hearing loss, while tumor size, poor hearing, and lobular growth were significantly related to postoperative useful hearing loss.

Summary: Currently, it is unpredictable to preserve hearing after vestibular schwannoma surgery, although the auditory nerve can be preserved in many cases. Apart from the wait and scan strategy and stereoradiotherapy, long-term follow-up shows stable hearing after surgery.

Summary: This study investigated the impact of the extent of internal acoustic meatus tumor removal on large acoustic neuroma surgery outcomes, finding a correlation with poor postoperative facial function. Younger age, larger tumors requiring radiosurgery, and more extensive tumor removal were associated with better tumor control.

Summary: This article reviews recent advances in the management and treatment of vestibular schwannoma, particularly in hearing preservation. By improving intraoperative monitoring systems and conducting precise genomic analysis, the treatment of vestibular schwannomas is expected to be improved.

Summary: Surgery for small vestibular schwannomas can achieve excellent hearing preservation. Different grading systems have a significant impact on and correlate with postoperative hearing preservation. Tumor size appears to be more important than anatomical relationships.

Summary: The study evaluated the feasibility of the Suppression head impulse testing (SHIMP) in patients with vestibular schwannoma (VS), and found that SHIMP testing, especially with the addition of the ASAR parameter, could effectively monitor residual vestibular function.

Summary: Surgery for vestibular schwannoma can be performed using different techniques, including the middle cranial fossa, suboccipital, translabyrinthine, and retrolabyrinthine approaches. The retrolabyrinthine approach, which preserves the labyrinth, has been modified to achieve a higher hearing preservation rate of 79% in our department. This improvement is considered helpful for hearing preservation.

Summary: This study retrospectively evaluated the clinical and surgical outcomes of a large surgical series of vestibular schwannoma in North America over 20 years. The study found that facial nerve outcomes were correlated with cerebellopontine angle extension, tumor volume, facial nerve stimulation threshold, facial nerve consistency, preoperative facial nerve function, and history of a prior resection. The data supports a continuation of a strategy of gross total resection, modifiable by intraoperative findings and judgment.

Summary: This retrospective study aimed to evaluate the differences in postoperative hearing in patients who underwent immediate versus delayed microsurgical resection of vestibular schwannomas (VS). The results showed that patients who underwent early surgery had a higher hearing preservation rate compared to those who had delayed surgery.

Summary: This study evaluates hearing outcomes in patients with vestibular schwannoma (VS) during the modern era of cochlear dose restriction. The results show that factors such as age, baseline GR score, cochlear dose, and biological effective dose are correlated with hearing preservation. Increased tumor-free canal space is associated with better outcomes. Furthermore, patients who meet specific criteria have higher hearing preservation rates compared to the rest of the population.

Summary: This study conducted a systematic literature review and meta-analysis on long-term hearing preservation after stereotactic radiosurgery (SRS). The results showed that nearly 60% of patients can maintain their hearing after a median follow-up of 6.7 years. Young age, good hearing status, early treatment, small tumor volume, low marginal irradiation dose, and maximal dose to the cochlea were identified as favorable prognostic factors.

Summary: Bronchial schwannomas are rare tumors that can occur in various age groups and both genders. They can be difficult to differentiate from malignant diseases and should be included as a potential diagnosis for primary bronchial tumors.

Summary: The aim of this study was to analyze hearing loss in patients with Vestibular Schwannoma (VS) and investigate the relationship between tumor grade and hearing loss. The most common reason for consultation was progressive unilateral hearing loss, and there was no statistically significant association between tumor size and progressive unilateral hearing loss in these patients.

Summary: This study aimed to provide a cognitive profile of patients with untreated vestibular schwannoma (VS). The results showed that patients with VS exhibited impaired cognitive function in memory, psychomotor speed, visuospatial ability, attention and processing speed, and executive function compared to the control group. In addition, patients with right-sided VS performed worse than those with left-sided VS in memory, attention and processing speed, and executive function. The study also found a correlation between worse hearing and longer hearing loss duration with poorer cognitive performance in patients with VS. Therefore, including cognitive assessment in the routine clinical management of patients with VS may improve clinical decision-making and patients' quality of life.

Summary: The study found that hearing deterioration during observation before SRS reduced long-term hearing preservation rates in vestibular schwannoma patients, recommending SRS be done before hearing deterioration to preserve hearing.
