Abstract:
OBJECTIVE To clarify the hearing improvement and tympanic membrane healing of tympanoplasty in patients with chronic suppurative otitis media in the stationary phase with soft tissue shadow of mastoid bulla on mastoid CT,and to compare its hearing improvement and tympanic membrane healing with that of canal wall up mastoidectomy+tympanoplasty.METHODS A retrospective analysis was conducted on clinical data of inpatient surgical cases diagnosed with chronic suppurative otitis media in the stationary phase with soft tissue shadow of mastoid bulla by preoperative mastoid CT at the Department of Otolaryngology Head and Neck Surgery,the First Affiliated Hospital of Nanchang University between September 2020 and April 2022.Patients were divided into two groups based on the surgical procedure:Group A,tympanoplasty,including 23 cases of type Ⅰ tympanoplasty(A1)and 26 cases of type Ⅱ tympanoplasty with ossicular chain reconstruction(A2);Group B,canal wall up mastoidectomy+tympanoplasty,including 21 cases of canal wall up mastoidectomy with type Ⅰ tympanoplasty(B1)and 20 cases of canal wall up mastoidectomy with type Ⅱ tympanoplasty and ossicular chain reconstruction(B2).Each patient was followed up for one year postoperatively,and at approximately one year after the operation,otoscopy and pure-tone audiometry(PTA)and air-bone gap(ABG)measurements at four frequencies(500,1 000,2 000,and 4 000 Hz)were performed and compared to preoperative values.RESULTS The average PTA at 1 year postoperatively for group A(A1 and A2)and group B(B1 and B2)were(36.35±16.21)dB HL[(31.96±11.78)dB HL,(40.24±18.68)dB HL]and(35.85±12.19)dB HL[(40.24±18.68)dB HL,(39.69±13.69)dB HL],respectively.Compared with preoperative PTA,the difference was statistically significant with P<0.05.The average ABG at 1 year postoperatively for group A and group B were(16.07±6.69)dB HL[(15.16±5.48)dB HL,(16.88±7.63)dB HL]and(15.21±6.40)dB HL[(13.93±5.29)dB HL,(16.56±7.28)dB HL],respectively.Compared with preoperative ABG,the difference was statistically significant with P<0.05.There was no statistically significant difference in postoperative average PTA and ABG between group A and group B.There was no statistically significant difference in effective rate between group A and group B.The results of ear endoscopy at 1 year postoperatively showed that the tympanic membrane healed well in both group A and group B.CONCLUSION There is no significant difference in hearing improvement and tympanic membrane healing between the two surgical procedures of tympanoplasty and canal wall up mastoidectomy+tympanoplasty for patients with CSOM at rest with shadowing of the mastoid sinus on mastoid CT.In clinical work,patients with CSOM at rest who have soft tissue shadow in the mastoid sinus on mastoid CT can opt for simple tympanoplasty.
