Background Epidermal cysts are benign, slow growing cysts that often develop on the head, neck, chest, and back of adults. The most common method of surgical excision involves the use of a scalpel and often leaves a scar proportional to the size of the cyst. Therefore, minimally invasive techniques are required. Among these techniques, the CO 2 laser-based technique is minimally invasive and has lower complication rate, shorter recovery times, and lesser scarring. This paper aimed to compare the results and postoperative complications associated with a CO 2 laser-based excision against conventional surgical excision for epidermal cysts. Methods We surveyed 120 patients, aged 16 to 65 years, with epidermal cysts on the face measuring 0.5 to 2.2 cm in diameter. Twelve months later, we compared the scar length, recurrence rate, patient satisfaction, and complications between patients treated with CO 2 laser excision versus surgical excision. Results The mean scar length (12 months postoperative) after CO 2 laser excision was 0.30± 0.15 cm, and that following surgical excision was 1.23± 0.43 cm ( p = 0.001). The procedure time (time from incision after local anesthesia to the end of repair) was 16.15± 5.96 minutes for CO 2 laser excision versus 22.38± 6.05 minutes for surgical excision ( p = 0.001). The recurrence rates in the surgical excision group and CO 2 laser excision group were 3.3% and 8.3%, respectively; this difference was not statistically significant ( p = 0.648). Conclusion The cosmetic outcome of CO 2 laser excision is excellent. For epidermal cysts measuring 2.2 cm or smaller, CO 2 laser excision is recommended, especially when aesthetic outcome is considered important.
Performing rhinoplasty using filler injections, which improve facial wrinkles or soft tissues, is relatively inexpensive. However, intravascular filler injections can cause severe complications, such as skin necrosis and visual loss. We describe a case of blepharoptosis and skin necrosis caused by augmentation rhinoplasty and we discuss the patient’s clinical progress. We describe the case of a 25-year-old female patient who experienced severe pain, blepharoptosis, and decreased visual acuity immediately after receiving a filler injection. Our case suggests that surgeons should be aware of nasal vascularity before performing an operation, and that they should avoid injecting fillers at a high pressure and/or in excessive amounts. Additionally, filler injections should be stopped if the patient complains of severe pain, and appropriate measures should be taken to prevent complications caused by intravascular filler injections.
Squamoid eccrine ductal carcinoma (SEDC) is an exceedingly rare tumor that shows both squamous differentiation and adnexal ductal differentiation. As our review of the literature revealed, only a total of 7 cases were reported to date. We report an additional case of SEDC occurring on the scalp of a 53-year-old man. Despite complete excision by conventional technique with clear margin, the lesion recurred within a 3-month period, with regional lymph node metastasis. The tumor was completely removed, and the large scalp defect was reconstructed by using scalp rotation flap. We present a case of recurrent SEDC on the scalp, and we surgically resected this tumor. In addition, the large scalp defect was reconstructed successfully with scalp flap, and no recurrence has been observed in the patient's postoperative follow-ups.
Transient anisocoria is rare during blowout fracture reconstruction. We report a case of transient anisocoria occurring during medial blowout fracture reconstruction and review the relevant literature. A 54-year-old woman was struck in the face and was admitted for a medial blowout fracture of the left eye. During the operation, persistent bleeding occurred. To control this bleeding, a 1% lidocaine solution with 1:200,000 epinephrine was applied to the orbital wall with cotton pledgets. In total, 40 mL of local anesthetic was used for the duration of the operation. After approximately three hours of the surgery, the ipsilateral pupil was observed to be dilated, with sluggish response to light. By 3 hours after the operation, the mydriasis had resolved with normal light reflex. In conclusion, neurological and ophthalmologic evaluation must be performed prior to blowout fracture surgery. Preoperative ophthalmic evaluation is simple and essential in ruling out any preexisting neurologic condition. Moreover, surgeons must be aware of the fact that excessive injection of lidocaine with epinephrine for hemostasis during orbital wall surgery can result in intraoperative anisocoria. Anisocoria-related situations must be addressed in a proficient manner through sufficient understanding of the mechanism controlling the pupillary response to various stimuli.
Sorafenib controls the mesenchymal characteristics of EBV-infected ARPE cells. Nardilysin and ADAM family proteins might be new targets for the prevention or control of EMT in retinal diseases.
