ABSTRACT
Objective: To investigate the feasibility and safety of auricle reconstruction combined with Bonebridge implantation for bilateral aural atresia patients. Methods: A retrospective analysis was conducted for 36 cases(72 ears) who underwent Bonebridge implantation combined with bilateral auricle reconstruction from February 1, 2017 to January 15, 2020. All cases were bilateral congenital aural atresia and underwent Nagata auricle reconstruction for both sides simultaneously. Bonebridge implantations were performed during the second stage of auricle reconstruction. Results: All 36 patients healed well and had no surgical complications when discharged. The preoperative average bone conduction threshold of the patients was(8.5±5.8) dB HL and postoperative bone conduction threshold was (8.4±5.2) dB HL. There was no significant change after the implantation (P=0.724). The preoperative average air conduction threshold of was(64.9±7.4)dB HL and postoperative air conduction threshold was (24.0±5.3) dB HL, which had a significant change after the implantation (P<0.001). The hearing threshold with Bonebridge significantly decreased by 40.9 dB HL compared with the preoperative air conduction threshold(P<0.001). The speech recognition rate of monosyllable words, disyllabic words and short sentences in quiet environment increased by 62.5%, 63.5% and 72.2% respectively. The differences were statistically significant (P<0.001). The speech recognition rate of monosyllabic words, disyllabic words and short sentences in noise environment were significantly increased by 55.9%, 58.9% and 69.9% respectively (P<0.001). After a follow-up of 18.3 months in average, the hearing results were stable and the aesthetic outcomes were satisfied. One patient had implant rupture and healed after revision surgery. Conclusions: With an integrated surgical procedure, patients with bilateral congenital aural atresia can complete bilateral auricle reconstruction and hearing implantation within six months. This integrated surgical procedure is safe and efficient, with a stable hearing improvement and good appearance.

Objective: To investigate the curative effect of rib cartilage framework supporting combined with local flap grafting for correction of cryptotia. Methods: Fourteen cases (nineteen ears) were corrected by rib cartilage framework supporting combined with local flap grafting method from January 2017 to March 2019. Part of the 7th rib cartilage was carved into a scalloped cartilage piece, which was implanted on the retroauricular cartilage to release and expand the deformed cartilage. A "M" incision was designed on the retroauricular skin to make the local flap grafting. Results: All corrected auricles were followed up for four months to three year and abtained satisfactory and stable appearance. In one case, the edge of the helix was broken two weeks after the operation, and well healed after repairing. Conclusions: The rib cartilage framework supporting combined with local flap grafting method can fully correct the deformity of cryptotia, and the long-term effect is satisfied. It can be an important complement to the classic methods.

Seven species were reported as new records of Jiangxi province, which collected from Wugongshan region, including Huperzia kunmingensis(Lycopodiaceae), Hydrangea mangshanensis(Saxifragaceae), Itea glutinosa(Saxifragaceae), Stellaria monosperma var. japonica(Lycopodiaceae), Youngia pratti(Compositae), and Calanthe henryi(Orchidaceae), Collabium formosanum(Orchidaceae). Among these species, H. kunmingensis, H. mangshanensis, I. glutinosa, Y. pratti and C. henryi are endemic in China. C. henryi is stenotopic distribution in China and regarded as vulnerable endangered plant by IUCN. The report is of great significance to the plant diversity and floristic composition in Jiangxi. All the specimens examined are preserved in Jishou University (JIU) and Sun yat-sen University (SYS).
