M W Ho, J S Brown, R J Shaw
Mandibular reconstruction in osteoradionecrosis or salvage surgery can often be complicated by the lack of suitable recipient vessels in the ipsilateral neck and the associated requirement for significant extraoral skin reconstruction. The scapula tip with its long vascular pedicle and option of a chimeric soft tissue component offers a versatile reconstructive solution in such cases. This article reports four consecutive cases of mandibular reconstruction with poor ipsilateral vascular options and additional soft tissue requirements in which the scapula tip was justified and preferred...

M Lääveri, K Heikinheimo, D Baumhoer, P J Slootweg, R-P Happonen
Periosteal fasciitis, considered a subtype of nodular fasciitis, is a rare benign soft tissue mass often misdiagnosed as a malignant lesion due to its fast and infiltrative growth pattern and histological features. Nodular fasciitis is usually found in the upper extremities in adults and in the head and neck region in children. Incorrect diagnosis may lead to overtreatment, potentially causing disturbed orofacial development in growing children. A rapidly growing asymptomatic mass, initially suspected to be a malignant bone tumour, was found in the left angle area of the mandible in a healthy 7-year-old girl...

One of the most important prognostic factors in oral squamous cell carcinoma (OSCC) is the presence of lymph node metastasis. Therefore, the early detection of late-presenting cervical lymph node metastasis is important. Although many studies have assessed diagnostic modalities for detecting metastatic cervical lymph nodes, no study has evaluated the process, especially first signs, for detecting late-presenting cervical lymph node metastasis. A retrospective analysis comparing methods for detecting the first signs of late-presenting lymph node metastasis was performed...
