ABSTRACT
Background@#The aim of this study is to investigate the clinical effectiveness of Ponto in Korea, a recently released percutaneous bone-anchored hearing implant. @*Methods@#16 patients with single-sided deafness (SSD) and mixed or conductive hearing loss who underwent Ponto implantation from December 2018 to September 2020 were enrolled in the study. Puretone audiometry, the Korean version of the Hearing in Noise Test (K-HINT), sound localization test (SLT), and Pupillometry were performed pre- and three months post-operation. Standardized questionnaires, the Hearing Handicap Inventory for the Elderly (HHIE) and Speech, Spatial and Qualities of Hearing Scale (SSQ), were administered. @*Results@#The mean age of subjects was 55.5 (range, 48–67) years. Four males and 12 females participated in the study. The mean puretone average was 73.17 dB hearing level (HL) before surgery and significantly improved to 36.72 dB HL three months after surgery. The mean word recognition score improved from 26.0% to 90.75% after implantation. In the case of K-HINT, there was a significant difference in summation (Z = −2.250, P = 0.024) and head shadow effects (Z = −3.103, P = 0.002). There was no significant difference in root mean square error degree (RMSE) and hemifield identification scores for SLT testing. Pupillometry was performed to measure listening effort and the results revealed that the degree of pupillary dilatation decreased under the condition of quiet, 0 dB signal to noise ratio (SNR) and 3 dB SNR. The total score for HHIE decreased significantly (Z = −3.130, P = 0.002) while the SSQ score increased significantly (Z = −2.216, P = 0.027). @*Conclusions@#The Ponto bone-anchored hearing system showed significant clinical benefit in Korean patients with conductive and mixed hearing loss and SSD.
ABSTRACT
Osseous hemangioma typically occurs in the vertebral column or skull bones. It it is extremely rare in the nasal bone. Only nine cases originating in the turbinate and maxillary bone have been reported in the English and Korean literature. Herein, we present the case of a 51-year-old women with a dorsum mass to share our experience with intraosseous hemangioma successfully removed and reconstructed by an endonasal approach.
ABSTRACT
PURPOSE: The US examination has been used to evaluate the infant and child having an inguino-scrotal bulge or mass for the non-invasive diagnostic work up to exclude neoplasm, cryptorchidism, lymphadenopathy, hydrocele of spermatic cord, etc. We performed this study to determine the characteristic ultrasound features of hydrocele of spermatic cord in children. MATERIALS AND METHODS: From February 2002 to March 2007, 213 pediatric patients with swelling or palpable mass of the inguino-scrotal area, or suspected cryptorchidism underwent ultrasonography for evaluation of accurate diagnosis. Ninetythree of 213 patients had a cystic lesion of the inguino-scrotal area. Among 93 patients, the sonographic images of 28 patients, who were confirmed as having hydrocele of the spermatic cord, were collected on a retrospective basis. The age of the patients ranged from 15 days to 11 years. The ultrasound images of the patients were subsequently reviewed to analyze the typical features in the diagnostic workup of hydrocele of spermatic cord. Eight patients were confirmed by surgery. Twenty patients who were less than one year old were clinically followed up. RESULTS: The most common finding was testicular hydrocele, which was found in 44 patients of the 93 patients that had a cystic lesion of the inguino-scrotal area. Of the 28 patients who had a hydrocele of spermatic cord, 10 patients had the lesions on the left side and 17 patients on the right side. One patient has bilateral hydrocele of spermatic cord. Well-defined elongated or elliptical-shaped cystic lesions were noted in the 24 of 29 cases (one patient had bilateral hydrocele of the spermatic cord). One patient had septations within elongated cystic lesion was seen and round shape in one case; tear drop shape was found in three cases. CONCLUSIONS: The most common ultrasound imaging of spermatic cord hydrocele is well-defined, elongated cystic mass separating the testes.
