A case report of nasopharyngeal inflammatory myofibroblastoma in infant / 临床耳鼻咽喉头颈外科杂志

Inflammatory myofibroblastic tumor （IMT） is a rare mesenchymal soft tissue tumor characterized by borderline or low-grade malignancy. It is rare childhood tumor with an average age of onset of 10 years old. It is even rarer in infants and toddlers, and the etiology and pathogenesis of this tumor are still unclear. The clinical presentation of IMT is non-specific and are related to the location of the tumor. When the tumor compresses adjacent organs, it can cause pain and functional impairment. According to the current literature, IMT is most commonly found in the digestive and respiratory systems, but also occasionally occur in the genitourinary system, head and neck, and limbs. At present, there have been no reports of nasopharyngeal IMT involving nasal cavity of infants and toddlers at home and abroad.This article reports a case of a massive inflammatory myofibroblastic tumor involving the nasal cavity and nasopharynx in an infant. Plasma-assisted minimally invasive surgery was performed through multiple surgical approaches and achieved satisfactory therapeutic results. This case report may provide valuable reference for the treatment of similar diseases.

The Preliminary Analysis of the List Equivalency of Disyllabic Materials for Mandarin Speech Perception Test in Cochlear Implant Users / 听力学及言语疾病杂志

Objective To evaluate the inter -list equivalency of the disyllabic materials for Mandarin speech perception test (MSP) by measuring the speech recognition score of patients with cochlear implant (CI) .Methods According to Latin -square design ,disyllabic recognition scores (quiet background) were measured for each of the 10 phonemically balanced lists in 50 Mandarin-speaking CI users(aged 30 .44 ± 12 .71 years)in sound field .RM -ANOVA was administered to confirm the list equivalency .Results The sentence recognition scores were 59 .26% ± 23 .49% ,64 .31% ± 23 .35% ,59 .97% ± 23 .07% ,62 .40% ± 25 .16% ,62 .75% ± 24 .47% ,62 .29% ± 23 .55% , 62 .85% ± 24 .60% ,61 .35% ± 23 .73% ,61 .82% ± 25 .28% ,58 .83% ± 25 .13% ,respectively for the 10 lists .There was no significance difference in sentence recognition scores across the 10 disyllabic lists [F(9 ,490)=0 .255 ,P=0 .986>0 .05] .Conclusion The good inter -list equivalency of the disyllabic materials for Mandarin speech perception test (MSP) has been proved to be useful for assessing speech recognition performance of Mandarin -speaking CI users .
