BackgroundThe ear is composed of elastic cartilage as its framework, and is covered with a thin layer of skin. Auricular reconstruction using autogenous cartilage in microtia patients requires delicacy. This paper reports clinical experiences related to elevation of reconstructed ear in the last 11 years.MethodsThis study was based on 68 congenital microtia patients who underwent auricular elevation in our hospital. Among these 68 patients, 47 patients were recruited. We compared the differences in the ear size, auriculocephalic angle, and conchal depth with those in the opposite ear, and the patients' satisfaction levels were investigated using a survey.ResultsThe difference in the sizes of the two ears was less than or equal to 5 mm in 32 patients, 5 to 10 mm in 10 patients, and greater than or equal to 10 mm in 5 patients. The difference in the auriculocephalic angles of the two ears was less than or equal to 10 degrees in 14 patients, 10 to 20 degrees in 26 patients, and greater than or equal to 20 degrees in 7 patients. The difference in the conchal depths of the two ears was less than or equal to 5 mm in 24 patients, 5 to 10 mm in 19 patients, and greater than or equal to 10 mm in 4 patients. The average grade of 3.9 points out of 5 points was obtained by the patients with satisfactory surveys.ConclusionWe could make enough protrusion and maintain the three-dimensional shape for a long time to satisfy our patients.

Malignant tumors of the hand are rare. Squamous cell carcinoma (SCC) is the most common tumor that can develop at the nail bed. However, its prevalence is extremely rare. We report a male patient with SCC in the middle finger and provide a review of related literature. A 70-year-old male patient presented with subungal exudate of the right middle finger for 2 years. The lesion was treated by the patient himself without any relief. He visited the other hospital and underwent removal of the affected fingernail followed by histopathological examination. An extended excision was performed to remove the lesion located in close proximity with the distal phalanx along with a portion of the phalangeal soft tissues. The tumor shows malignant squamous sheets and nests with invasive growth pattern and pleomorphism. At the 6-month postoperative follow-up, neither symptom relapse nor other complications were observed. Various types of skin cancers, such as SCCs and malignant melanomas, can develop in the hand. However, their incidence is extremely rare. In particular, subungal lesions, which may be mistaken as fungal nail infections, require histopathological examination if they respond only slowly to treatment.
