Summary: Understanding how to remove and retain the relatively large residual auricle is important in concha-type microtia reconstruction. The authors present a method for concha-type microtia reconstruction using a delayed postauricular skin flap. A total of 40 patients with concha-type microtia who underwent ear reconstruction using a delayed postauricular skin flap were retrospectively examined. Reconstruction was performed in three stages. The first stage consisted of preparing a delayed postauricular skin flap and dealing with the residual auricle including removal of the upper residual auricular cartilage. In the second stage, an autogenous rib cartilage framework was placed and covered with a delayed postauricular skin flap, postauricular fascia flap, and autologous medium-thickness skin graft. The ear framework was carefully articulated and secured with the retained residual auricular cartilage to achieve a smooth junction between the two. The third stage involved modification of the reconstructed ear. Patients were followed up for 12 months after ear reconstruction. All reconstructed auricles had a good appearance, and there was a smooth connection between the reconstructed auricle and the residual ear, with similar color as well as a flat and thin scar. All patients were satisfied with the results.
Clinical Question/level Of Evidence: Therapeutic, IV.

The authors describe a rare case of non-Hodgkin lymphoma (NHL) with primary involvement of the external auditory canal (EAC) and subsequent dissemination to the central nervous system, initially manifesting as a benign ear infection. This case highlights the importance of considering differential diagnoses in patients with persistent or worsening symptoms unresponsive to empirical treatment. A 53-year-old man presented with a one-week history of aural fullness, otalgia, and otorrhea in the left ear.

The authors present a case of a partial auricular deformity acquired from a human bite that was reconstructed using a 3-stage posterior auricular tubed flap. Helical rim avulsions may be ideally reconstructed with a tubed flap created from lax postauricular soft tissue. During the third stage, division and inset of the inferior pedicle of the flap were complicated by venous congestion.

Background: In the otology clinic, we often receive some sudden sensorineural hearing loss (SSNHL) patients accompanied by annoying tinnitus, who usually visited over three weeks after the onset. Nevertheless, due to the high treatment cost and relatively low cure rate, there are still great disputes about hospitalization or not for these patients. Aim: This study aimed to perform a retrospective analysis for analyzing the efficacy of treatment with oral steroids combined with postauricular steroid injection in patients with delaying effective treatment.
