Impact of Balance Training and Co-ordination Exercises in Post-Operative Left Cerebellopontine Angle Tumor: A Case Report

Introduction: Acoustic neuromas are most common tumors of CP angle, accounting more than 90% of all such tumors. Meningioma, primary cholesteratoma and facial nerve schwanoma are the different type of tumors. Acoustic neuroma is a benign tumor situates in CP angle which has a fibrous growth and originates from the division of vestibulochochlear nerve. Aim: Impact of Balance Training and Co-ordination Exercises in Post-Operative Left Cerebellopontine Angle Tumor Case Presentation: A 40 year old male with right hand dominance was referred to physiotherapy department. On examination he presented mild impairment in balance and co-ordination, assisted walking. Discussion: This case report is an important to the published literature on rehabilitation of a patient witha CPA tumor, as it presents the sequential management in the patients post CPA tumor. Conclusion: Acoustic neuroma is most common CPA tumor. Management of CPA tumor is important to improve quality of life. As per the reference articles and the exercises planned can progressively improve balance and co-ordination of patients.

Schwannoma of the Intermediate Nerve: A Rare Type of Cerebellopontine Angle Tumor

Background: Schwannoma of the Intermediate Nerve is rare. The most majority of Cerebellopontine angle (CPA) lesions are Vestibular Schwannomas. Case description: A 50-year-old woman presented with ear pain, facial palsy and hypoacusis. MRI revealed a CPA tumor. A left retrosigmoid approach and microsurgery was performed and the tumor origin was from the intermediate nerve. intraoperative neurophysiologic monitoring (MNIO) was used during the surgery. Conclusion: Schwannomas of the intermediate nerve is indistinguishable from vestibular schwannomas on preoperatory image, however it’s possible to identify tumor origin during microsurgery dissection with aid of MNIO and origin from intermediate nerve is a reality.

Lhermitte–Duclos Disease Mimicking Cerebellopontine Angle Tumor: A Case Report

Lhermitte-Duclos disease (LDD) is dysplastic gangliocytoma of the cerebellum, which is rare, tends to grow slowly, usually has good prognosis, and wherein the cerebellar cortex becomes thick and the central white matter is not observed. On MRI of the brain, it has hyperintense and hypointense presentations on T2- and T1-weighted scans, respectively. It has nonhomogenous contrasting pattern on T1-contrast scans. LDD can be seen unilaterally or bilaterally in the cerebellum. When the disease is located at the cerebellopontine angle, it can be mistaken for the tumors located in this region. Recurrence can occur postoperatively, which is rare. The present case is a rare one because the tumor was located at the cerebellopontine angle and radiologically mimicked cerebellopontine angle tumors.

Masseter-to-Facial Cranial Nerve Anastomosis: A Report of 30 Cases

BACKGROUND Facial nerve paralysis (FP) is a possible complication of cerebellopontine angle tumor surgery. Several donor nerves have been used in the past for facial reanimation. We report the results of 30 cases of masseter-to-facial anastomosis. OBJECTIVE To prospectively evaluate the efficacy of V to VII anastomosis after FP. METHODS In a prospective study, we included 30 consecutive patients with FP (20 women and 10 men) whose mean age was 48.8 yr (32-76 yr). In almost all cases, FP developed after cerebellopontine angle tumor surgery (29 patients), whereas in one case, FP occurred after skull base trauma. Pre- and postoperative evaluation of facial nerve function was performed using the House-Brackmann (HB) scale and the Sokolovsky scale, as well as by electromyography. Follow-up ranged from 11 to 51 mo and averaged 22 mo. RESULTS All patients achieved functional recovery of the facial nerve from VI to either III or IV HB degree. Patients with short time FP showed significantly better postoperative recovery. CONCLUSION The results of the V to VII anastomosis demonstrate a significant improvement of facial nerve function and virtually no complications.
