Microsurgical Treatment Of Postoperative Complications Of Acoustic Neuroma Analysis Of Related Factors

Objective To explore the common complications and related factors after microsurgery treatment of acoustic neuroma,improve the curative effect of surgical resection and reduce complications,shorten the average hospital stay and improve the quality of life after surgery.Methods From January 1,2018 to October 31,2020,the general and clinical data,surgical data,and postoperative and 6-month follow-up data of patients with acoustic neuroma who underwent surgery in Ningxia Medical University and Cardiovascular Hospital were retrospectively analyzed.SPSS 26.0 statistical analysis software was used for data analysis.Chi-square test was used for statistical analysis of each variable,and Fisher’s exact test was used for analysis of the cases where the expected frequency was less than 5 in some groups.Correlation analysis was used to explore the correlation between various influencing factors and facial nerve function grading and postoperative intracranial infection in patients 6 months after surgery.P < 0.05 indicated statistical significance.Results According to the inclusion criteria,a total of 47 patients with acoustic neuroma underwent surgical resection were included in this study.The most common postoperative complications were: facial nerve function(H-B grade: II-VI)in 33 patients(70.21%)and intracranial infection in 16 patients(34%).The following were cerebrospinal fluid rhinorrhea and subcutaneous effusion in 4 patients(8.51%),incisional infection in 3 patients(6.38%),intracranial hematoma in 3 patients(6.38%),nerve palsy in 2 patients(4.26%),abducens nerve palsy in 2 patients(4.26%)and vestibular palsy in 1 patient(2.13%).The results showed that the Koos grade of acoustic neuroma was statistically significant with the facial nerve function grade 6 months after operation(P=0.001 < 0.05).The results showed that the diameter of tumor and the duration of operation were statistically significant(P=0.015<0.05 and P=0.03<0.05)and correlated with the occurrence of postoperative intracranial infection(correlation coefficients r=0.0465 and r=0.344).There was no statistical significance between age,sex,tumor side,duration of disease,incision design,cystic degeneration,intraoperative blood loss and postoperative intracranial infection(P>0.05).Conclusion There was a significant linear correlation between facial nerve function grade and tumor Koos grade in patients with acoustic neuroma 6 months after surgery,that is,the higher the tumor Koos grade,the higher the postoperative facial nerve function H-B grade,that is,the worse the facial nerve function.There was no correlation between age,sex,cystic degeneration,duration of disease and lateral type of tumor and facial nerve function grade 6months after operation.There was a linear correlation between tumor diameter and operation duration and postoperative intracranial infection in patients with acoustic neuroma,that is,the larger the tumor diameter and the longer the operation duration,the higher the incidence of postoperative intracranial infection.There was no correlation between age,sex,cystic degeneration,duration of disease,tumor side and intraoperative blood loss.Because the anatomical relationship of CPA is extremely complex and the incidence of postoperative complications is high,the surgeon should make a detailed operation plan according to the characteristics of the patient and seek the best treatment plan for the patient.
