Evaluation of rehabilitation outcomes after cochlear implantation in later-implanted patients with prelingual deafness

Objective:To identify the changes in the quality of life and speech recognition ability of older pre-lingual deaf patients before and after cochlear implant surgery.Methods:A total of patients with pre-linguistic deafness who underwent unilateral cochlear implant surgery at the Sun Yat-sen Memorial Hospital of Sun Yat-sen University from February 2012 to November 2018 were taken as the research object.The CAP scale,SIR scale,and Nijmegen cochlear implant scale were used to assess the patient's condition for the quality of life before and 2 years after the operation,and compared the postoperative and preoperative scores were compared.At the same time,the angel language training was adopted.The auditory rehabilitation system and the Chinese open speech perception assessment system were used to test the speech recognition rate of patients before and 2 years after implantation.Results:The quality of life of patients undergoing cochlear implant surgery improved two years after the operation.CAP,SIR scores and NCIQ sub-fields(basic voice perception,advanced voice perception,speech ability,self-confidence,activity ability,and social communication)were significantly improved compared with those preoperatively,and the speech recognitionrate score was also improved.There was a significant correlation between the quality of life and speech recognition of the test patients.Conclusion:Cochlear implantation has a significant effect on improving the quality of life and speech recognition ability of older pre-linguistic deaf patients.The correlation between quality of life and speech recognition still needs to be further explored.Therefore,-,quality of life and language recognition are the assessment of older pre-linguistic deafness.The rehabilitation effect of patients after cochlear implantation needs to be considered at the same time.

Intact Canal Wall Mastoidectomy Combined with Balloon Dilation Eustachian Tuboplasty in the Treatment of Middle Ear Cholesterol Granuloma

To the Editor： Cholesterol granuloma （CG） refers to granulation tissue containing cholesterol crystals and giant cells and is a tbreign body response elicited by local tissues. The pathogenesis of middle ear CG can be explained using the classic obstruction-vacuum theory caused by negative middle ear pressure, The Eustachian tube （ET） plays a decisive role in influencing the gas exchange and maintaining the ventilation and pressure of the middle ear. The traditional treatment is mastoidectomy, routinely combined with middle ear ventilation tube insertion or tube insertion during re-examination after operation. Eustachian tuboplasty by balloon dilation can improve the pathological state of ET via specific mechanisms to achieve functional recovery and satisfactory clinical efficacy.
