Isolated Frontal Sinus Undifferentiated Carcinoma: First case Report in the Literature.

Sinonasal undifferentiated carcinoma (SNUC) is a rare tumor which is aggressive in nature, has a different clinical course in contrast to sinonasal carcinoma and poor prognosis. Here, we are reporting first case of isolated frontal SNUC which was managed by upfront surgery followed by adjuvant treatment. We want to emphasize the importance of early presentation and timely intervention in form of conservative surgery in this highly aggressive tumor.

Full-Extension Eyebrow Approach with Supraorbital Nerve Preservation for Frontal Sinus Tumors.

Frontal sinus surgery still represents a challenge due to its complex and highly variable anatomy. In this manuscript, we present a detailed anatomical description of an eyebrow approach that allows full exposure of the frontal sinus with a large osteoplastic bone flap and preservation of the supraorbital nerve.

Recurred forehead osteoma disseminated after previous osteoma excision: A case report.

BACKGROUND: Forehead osteoma is a commonly encountered benign facial bone tumor. Endoscopic excision of benign forehead masses is widely performed. Here, we report a rare case of recurrent forehead osteoma that disseminated after a previous osteoma excision. CASE SUMMARY: A 54-year-old female patient had previously undergone endoscopic removal of a single forehead osteoma at 30 years of age. However, she had a recurrent osteoma around the same site and underwent another endoscopic resection at 40 years of age. During her first visit to our outpatient clinic, she presented with a cobblestone-like irregular surface on the forehead and a 3D facial bone computed tomography scan revealed a widely ragged surface of the inoculated osteoma on the outer table of the frontal bone. Under general anesthesia, we performed a radical complete excision of the disseminated osteoma through a bicoronal incision using an osteotome, chisel, mallet, and rasping. We hypothesized that the recurrence may have been caused by the inoculation of residual osteoma remnants from the previous procedure. Craniofacial surgeons should be cautious when removing osteoma particles, particularly when using an endoscopic approach. CONCLUSION: To prevent recurrence, it is essential to conduct additional meticulous burring and a thorough inspection of the surface after copious irrigation.

A Case of the Huge Ethmoid Osteoma Involving the Skull Base and Orbit

Osteoma is a slow-growing benign tumor that consists of mature or cancellous bone. It most commonly occurs in the frontoethmoidal area of the paranasal sinus and is usually asymptomatic. Surgical excision is necessary for osteoma, which causes symptoms such as headache, nasal obstruction, facial asymmetry, and visual disturbance. Surgical approaches should also be considered depending on the size and location of the osteoma, in order to reduce intracranial and orbital complications. We recently treated a huge frontoethmoid osteoma involving the skull base and orbit, which was removed via endoscopic sinus surgery and a combined extracranial approach. Herein, we report this case with a review of the relevant literature.

A Survey of Patient Satisfaction after Treating Zygomatic Complex Fractures Using a Coronal Approach

PURPOSE: It is difficult to objectively evaluate the outcomes of plastic surgical procedures. The combination of aesthetic and medical factors makes outcome quantification difficult. In this study, fracture reduction accuracy was objectively evaluated in patients with zygomatic complex fractures. Patients satisfaction with the accuracy was also examined. In addition, the patients' overall satisfaction and discomfort due to complications were analyzed. METHODS: Eighty-five patients who had surgeries via bicoronal incision for zygomatic complex fracture from March 2006 to December 2009 were included in this study. Two plastic surgeons evaluated the accuracy of the fracture reduction with postoperative computed tomography. A survey questionnaire was administered to evaluate the patients' overall satisfaction and the impact of symptoms associated with the procedure on the patients' daily lives. RESULTS: The overall patient satisfaction rate was 82.1 +/- 10.9% (range, 45~100%). The level of deformation was 6.7 +/- 10.9%, the levels of discomfort in daily life due to pain, paresthesia, scar, and facial palsy were 8.5 +/- 13.2%, 5.8 +/- 8.9%, 4.4 +/- 9.9%, and 1.9 +/- 9.2%, respectively. According to the visual analogue scale, paresthesia was found to be the most frequent symptom (43.5%), and pain was the most troublesome symptom. CONCLUSION: The use of bicoronal incision for treating zygomatic complex fractures can cause various complications due to wide incision and dissection. However, this technique can provide optimized reduction and rigid fixation. Most of these postoperative complications can cause significant discomfort in the patient. It is thought that the use of correct surgical technique and the accurate knowledge of craniofacial anatomy will result in a reduction of complications and significantly increase patient satisfaction.

Nasal Dermoid Sinus Cyst Excision with Bicoronal Approach

Nasal dermoid sinus cyst is a rare congenital lesion. It may present extracranially as a swelling or a mass on the nose, a skin pit or a sinus. Intracranial complications can be fatal including meningitis, abscess, osteomyelitis, seizures. The treatment of choice is complete surgical excision of the cyst. There are some approaches to this goal such as vertical midline incision, external rhinoplasty approach, bicoronal approach, and endoscopic approach. In this case, we could completely excise the nasal dermoid sinus cyst on the glabella without intracranial extension only with bicoronal incision.

Removal of Orbital Osteoma Using Bicoronal Approach

Osteomas are benign tumors, which occur in various bones of the body, and it is mostly located in skull and facial bones. Osteoma of orbital area may produce ophthalmologic symptoms and cosmetic problem, for which cases surgical removal is recommended. We report two cases of orbital osteomas occurred in young women, which were removed by bicoronal approach for the purpose of cosmetic effect.
