OBJECTIVE: A general orientation along the cervical spine could be estimated by external landmarks, and it was useful, quick and less exposable to radiation, but, sometimes it gave reference confusion of target cervical level. The authors reviewed the corresponding between the neck external landmarks and cervical levels. METHODS: Totally 1,031 cervical lateral radiographs of different patients were reviewed in single university hospital. Its compositions were 534 of males and 497 females; 86 of second decades (10-19 years-old), 169 of third decades, 159 of fourth decades, 209 of fifth decades, 275 of sixth decades, and 133 of more than seventh decades (>60 years-old). Reference external landmarks (mandible, hyoid bone, thyroid cartilage, and cricothyroid membrane) with compounding factors were reviewed. RESULTS: The reference levels of cervical landmarks were C2.13 with mandible angle, C3.54 with hyoid bone, C5.12 with thyroid cartilage, and C6.01 with cricothyroid membrane. The reference levels of cervical landmarks were differently observed by sex, age, and somatometric measurement (height) accordingly mandible angle from C1 to C3, hyoid bone from disc level of C2 and C3 to C5, thyroid cartilage from disc level of C3 and C4 to C7, and cricothyroid membrane from C4 to disc level of C7 and T1. CONCLUSION: Surface landmarks only provide general reference points, but not correspond to exact levels of the cervical spine. Intraoperative fluoroscopy ensures a more precise placement to the targeted cervical level.

Xeroderma pigmentosum is a rare autosomal recessive disease, related to defects in DNA repair mechanism. It presents skin lesions on sun-exposed areas, leading to various skin cancer. Skin lesions can be treated with cryotherapy, skin resurfacing, 5-FU, Imiquimod, topical T4 endonuclease V, radiotherapy and genetic therapy, but invasive skin cancer should be treated by a surgery. We report a 12-year-old female xeroderma pigmentosum patient with recurrent basal cell carcinoma successfully treated by skin grafting. In that there is no cure for this disease, prevention and patient education is most important.

Forehead flaps are widely used to reconstruct nasal defects. The authors report a case wherein a folded forehead flap was used to reconstruct a large nasal defect after wide excision of squamous cell carcinoma. A 65-year-old man was diagnosed with squamous cell carcinoma by a punch biopsy conducted at the dermatology department, and the mass was located in the left nasal vestibule. A forehead flap was planned to cover the full-thickness defect that occurred after wide excision. A flap with an extended transverse skin paddle was designed; thereafter, the distant part of the flap was folded up to the nasal lining inside the nose. The interpolation flap was properly maintained for 3 weeks, and flap division was performed. The reconstructed nose exhibited symmetry during a 5-month observation period. A folded forehead flap is a surgical option when considerable nasal restoration, including soft tissue and the internal lining, is necessary.

Anterior shoulder dislocation is a common injury among athletes, particularly during resistance training, where muscle resistance can complicate reduction procedures. In muscular patients, traditional reduction techniques may be challenging due to increased muscle tone and resistance. This case report describes a 29-year-old male patient who suffered an anterior shoulder dislocation while performing bench press exercises. Ultrasound-guided brachial plexus block (BPB) was used, resulting in effective pain relief and muscle relaxation, enabling successful reduction without sedation or general anesthesia. This report highlights the utility of BPB in managing difficult reductions, particularly in patients with significant muscle mass.
