Surgical treatment of auricular concha, the helix root and the external auditory canal tumours, and their reconstruction, is a challenge because of the complexity of this anatomic region and the significant functional and aesthetic requirements of these treatments. The purpose of this study is to describe our experience with the retroauricular revolving door island flap technique.

This was a retrospective descriptive study (series of nine clinical cases) conducted between 2020 and 2023 of revolving door island flap reconstruction of auricular conchal and external auditory canal defects caused by tumour removal.

In all the cases, tumour-free margins and total reconstruction of the defect were achieved through the revolving door island flap intervention, with optimal aesthetic and functional results.

Revolving door island flap reconstruction is a viable surgical option for the reconstruction of auricular conchal and external auditory canal defects because of its versatility, reproducibility, low post-operative morbidity and optimal results.

The association between diagonal earlobe crease and cardiovascular disease has been known for several decades. This review investigated whether there is a significant association between the presence of a diagonal earlobe crease and coronary artery disease independent of other confounding factors.

This study was a systematic review and meta-analysis of selected studies using the Preferred Reporting Items for Systematic Reviews and Meta-analyses checklist.

This study included 12 studies in the pooled analysis with 2415 cases and 2545 controls. The study found that patients with diagonal earlobe crease have an increased (four times) likelihood of having coronary artery disease. In addition, despite some previous studies suggesting that diagonal earlobe crease was simply a result of age, all 10 of the included studies that looked at this found that the relationship between diagonal earlobe crease and coronary artery disease was independent of both age and other known cardiovascular risk factors.

Patients with diagonal earlobe crease appear to have an increased risk of coronary artery disease, and this may be higher for patients with bilateral diagonal earlobe crease.

We report the case of a rare angiosarcoma, retiform haemangioendothelioma, in an 18-year-old young man, which presented as a recurrent ulcerating lesion of the left pinna.

Case report and literature review of retiform haemangioendothelioma. This is a low grade angiosarcoma with a high local recurrence rate and low metastasis rate, and was first described in 1994 by Calonje et al.

This patient represents only the third report of lymph node metastasis in a case of retiform haemangioendothelioma. To date, 31 cases of the tumour have been reported. Histological diagnosis of this group of vascular neoplasms can be challenging, as their histopathological appearance is intermediate between haemangioma and angiosarcoma.

Surgical excision remains the primary treatment modality, with adjuvant radiotherapy recommended in patients with large tumour size, local recurrence and lymph node metastasis, as seen in this case.

To describe a new treatment for perichondritis and haematoma of the pinna. At present, the existing treatment for these conditions is initially medical (which usually fails), followed by surgery (incision, drainage and compression to prevent recurrence) with accompanying medical management. However, the result is often a failure, resulting in partial or complete ‘cauliflower ear’ deformity.

The described treatment involves draining the site of infection and irrigating with streptomycin solution. The cavity is then filled with a solution of streptomycin, hyaluronidase and triamcinolone.

The described treatment avoids the conventional surgical procedure, which is cumbersome for surgeons and harrowingly painful for patients.

The new treatment may be recommended for universal use.
