Soft tissue defects resulting from head and neck tumor resection seriously impact the physical appearance and psychological well-being of patients. The complex curvature of the human head and neck poses a formidable challenge for maxillofacial surgeons to achieve precise aesthetic and functional restoration after surgery. To this end, a normal head and neck volunteer was selected as the subject of investigation. Employing Gaussian curvature analysis, combined with mechanical constraints and principal curvature analysis methods of soft tissue clinical treatment, a precise developable/non-developable area partition map of the head and neck surface was obtained, and a non-developable surface was constructed. Subsequently, a digital design method was proposed for the repair of head and neck soft tissue defects, and an in vitro simulated surgery experiment was conducted. Clinical verification was performed on a patient with tonsil tumor, and the results demonstrated that digital technology-designed flaps improved the accuracy and aesthetic outcome of head and neck soft tissue defect repair surgery. This study validates the feasibility of digital precision repair technology for soft tissue defects after head and neck tumor resection, which effectively assists surgeons in achieving precise flap transplantation reconstruction and improves patients' postoperative satisfaction.

The patient complained of a 20 days history of isolated mass in the right cervical region. The lesion was successfully eradicated by surgical removal. Histopathology established branchial cleft cyst carcinoma (BCCC) as the diagnosis. More attentions should be paid to the diagnosis of BCCC. Primary leisions were essential for the suspected cases. Importantly, only after excluding the metastatic squamous carcinoma in lymph nodes and other primary diseases, the diagnosis of BCCC would be established. Therapeutic strategies include complete local excision, radical neck dissection, and post-operative radiotherapy.

78 patients with Port wine stains (PWS) were treated by surgical method. The result showed that surgery is useful and effective. However, surgical scars are common and the skin grafts have more dark color than surrounding (if the skin grafts were required). So it must be very carefully in making a decision for surgery and choose a suitable method for each patient. The surgery is attempted to close local skin. And in case of the skin graft is required, it is better to take a full thickness skin graft in areas near to the face and neck.
