A Method for Precise Reduction of Facial Bone Fractures Using Intraoperative Ultrasound With a Solid Gel Pad as a Coupling Medium.

This study introduces a method to overcome technical challenges in using intraoperative ultrasound for the closed reduction of nasal bone and zygomatic arch fractures. The curvature of the face makes it difficult to apply an ultrasound probe to the facial area. We used a solid gel pad as a coupling medium during surgery to improve the scanning of facial bone fractures. The results show that the fracture sites observed on preoperative computed tomography scans can be easily visualized using intraoperative ultrasound, and real-time manipulation confirms successful reduction. The solid gel pad is light, malleable, easy to use, and provides accurate images. Overall, the use of ultrasound with a solid gel pad enhances the accuracy of closed reduction in facial bone fracture surgeries, confirming fracture patterns and ensuring precise reduction.

Breast US in patients with breast cancer presenting as only microcalcifications on mammography: can US differentiate ductal carcinoma in situ from invasive cancer?

PURPOSE: To retrospectively review sonographic findings of breast cancers presenting as only microcalcifications on mammography and to evaluate factors essential for differentiating ductal carcinoma in situ (DCIS) from invasive cancers. METHODS: We retrospectively reviewed the medical records of 620 consecutive patients with confirmed breast cancer according to surgery performed between March 2008 and October 2011 at our institution. Of these, 53 lesions from 52 patients who had only microcalcifications without a mass or other associated findings on mammography were selected. Sonographic findings of microcalcification areas were analyzed and correlated with the histopathological findings. RESULTS: Of the 53 lesions, 26 (49.18 %) were classified as invasive cancer and 27 (50.9 %) as DCIS. Ultrasonography (US) showed only echogenic calcifications in five (9.4 %), calcifications within hypoechoic parenchymal thickening in 14 (26.4 %), calcifications within ductal changes in three (5.7 %), and calcifications within a mass in 14 (26.4 %). Seventeen (32.1 %) lesions were not visible on US. Negative findings in US were more frequently observed for DCIS (n = 15, 55.6 %) than for invasive cancers (n = 2, 7.7 %) (p < 0.001). Masses (n = 11, 42.3 % of invasive cancer; n = 3, 11.1 % of DCIS; p = 0.01) were more frequently observed in invasive cancers than in DCIS. CONCLUSIONS: US findings of breast cancers presenting as only mammographic microcalcifications were significantly different between DCIS and invasive cancers. Targeted US of microcalcifications might be helpful for predicting invasive cancers and for determining the clinical preoperative work-up, including axillary staging.

Removal of an intraosseous hemangioma of the frontal bone through an anterior hairline incision: a case report.

An intraosseous hemangioma of the frontal bone is typically removed via a coronal incision. This procedure, while effective, can be lengthy and may result in complications such as a prominent scar and hair loss. An alternative approach involves a direct incision in the forehead, which leaves a less noticeable scar and allows a quicker recovery. However, in this specific case, the patient declined both coronal surgery and surgery through a direct forehead incision due to cosmetic concerns. Therefore, we proposed an anterior hairline incision. A 35-year-old woman presented with a firm, non-mobile, palpable mass on her right forehead. Preoperative non-contrast computed tomography revealed a heterogeneous osteolytic lesion. We performed an excisional biopsy through the anterior hairline. Postoperative non-contrast computed tomography was conducted 2 and 6 months after surgery. The wound was clean and free of complications, and there was no local recurrence. Partial resection can reduce scarring for patients who are concerned about cosmetic outcomes. However, the potential for recurrence remains a significant concern. We present this case of an anterior hairline incision for a hemangioma located in the forehead, evaluated using serial computed tomography for both preoperative and postoperative imaging.

Correction of the supratip deformity of the nose.

BACKGROUND: A supratip deformity can develop either congenitally or after a poorly executed rhinoplasty, as a result of fullness or convexity just above the nasal tip. OBJECTIVE: In this article, the authors describe the causes of the supratip deformity and present their technique for surgical correction. METHODS: A retrospective chart review was conducted for 62 consecutive patients (24 primary rhinoplasty and 38 secondary rhinoplasty) treated between January 2005 and February 2010. The authors' approach to managing supratip deformity included a combination of wide undermining of the nasal skin through the open technique; resection of excessive soft tissue and the bony, cartilaginous dorsum; suturing to advance the supratip; and augmentation of the nasal tip and dorsum with cartilage, crushed cartilage, silicone implants, and/or septal extension grafts. RESULTS: No infection or nasal bleeding was recorded during postoperative follow-up. The supratip and tip projection showed adequate shape in all cases. To assess satisfaction, all patients and 2 independent plastic surgeons were asked to rate the result on a 5-point scale. The average patient satisfaction rating was 4.2 and the average independent rating was 4.4 points. CONCLUSIONS: Supratip deformities should be corrected according to their unique cause and shape. The authors' method of repairing these deformities has resulted in a low complication rate and yielded satisfactory results.

Clinical association between serum cholesterol level and the size of xanthelasma palpebrarum.

BACKGROUND: Xanthelasma palpebrarum (XP) is a benign periorbital lesion. The relationship between xanthelasma lesion size and serum cholesterol levels has been poorly studied. In this study, we investigated this relationship in the context of the clinical etiology of XP. METHODS: We retrospectively reviewed medical records and pathology reports of all patients treated for XP at our hospital between June 2014 and June 2021; the data were used to analyze lesion size, underlying disease, serum cholesterol, and disease recurrence. RESULTS: The mean values for patient age, serum cholesterol, and lesion size were 53.0 years, 235.0 mg/dL, and 69.2 mm2, respectively. XP mainly occurred in women (64.7%); furthermore, the incidence of XP and lesion size was greatest among patients in their 5th decade of life (41.2%). There was no statistically significant relationship between xanthelasma lesion size and serum cholesterol level. CONCLUSION: This study compared lesion size with various clinical features in XP patients. In patients who underwent surgery for XP, serum cholesterol levels tended to be higher than those in the general population. However, the trend between the size of XP and serum cholesterol level was unclear. Therefore, if a patient with XP visits the hospital for surgery, it is recommended to check the lipid profile to confirm underlying dyslipidemia regardless of the size.

Comparison of intermaxillary fixation techniques for mandibular fractures with focus on patient experience.

BACKGROUND: Intermaxillary fixation (IMF) is a technique that allows for the reduction and stabilization of mandibular fractures. Several methods of IMF, such as self-tapping screws or arch bars, have been developed. This study aimed to validate the usefulness of IMF with a self-tapping screw compared to IMF with arch bars with focus on the patients' perspective. METHODS: We retrospectively reviewed the medical records of all patients who were treated for mandibular fractures at our hospital between August 2014 and February 2021. A total of 57 patients were enrolled in this study. Thirteen patients were excluded from the analysis: three patients were lost to follow-up, and 10 patients did not undergo IMF. Finally, 44 patients were analyzed, of which 31 belonged to the arch bar group, and 13 belonged to the screw group. Patient discomfort and pain during IMF application and removal were analyzed using a patient self-assessment questionnaire. The surgeon also assessed oral hygiene, IMF stability, and occlusion. RESULTS: We applied IMF to 34 men (77%) and 10 women (23%). The mean age of the patients was 37.3 years. The most common fracture site was the angle (30%), followed by the parasymphysis (25%), the body (23%), the condyle (11%), and the ramus (11%). Patient discomfort and oral hygiene were statistically favorable in the screw group. The IMF application time was statistically shorter in the screw group (p< 0.001). IMF stability was not statistically different between the two groups. The pain score during IMF removal was lower in the screw group (p< 0.001). CONCLUSION: Compared to arch bars, IMF screws provide more comfort during the IMF period, help maintain favorable oral hygiene, and have a shorter application time. From the patient's perspective, IMF screws are an excellent alternative to conventional arch bars when applicable.

Optimal harvest and efficient use of septal cartilage in rhinoplasty.

BACKGROUND: Nasal septal cartilage is used to obtain favorable aesthetic and functional outcomes in rhinoplasty, but is often difficult to harvest or the harvested amount is insufficient. Therefore, the objective of this study is to introduce how to harvest septal cartilage optimally without losing and use harvested cartilage efficiently. METHODS: From March 2015 to January 2020, we tried to harvest as much septal cartilage as possible while maintaining the L-strut in 30 patients. A spreader flap and septal rotation suture were used instead of a spreader graft. Also in patients who needed a spreader graft and septal extension graft, a spreader graft was used on one side and a one-piece spreader graft combined with a septal extension graft was performed on the other side. For tip plasty, a columella septal suture was performed first. Postoperative patient satisfaction was assessed using the Rhinoplasty Outcome Examination questionnaire. RESULTS: No serious complications were observed. The patient satisfaction score was 50% or above in 27 patients (90%) and less than 50% in only three patients (10%). The average score was 81.5 points. CONCLUSION: For septal cartilage deficiency, a spreader flap, the septal rotation suture, or onepiece spreader graft combined with a septal extension graft was used. The nasal tip was sufficiently rotated using the columellar septal suture technique first. These techniques made it possible to obtain good aesthetic outcomes using only septal cartilage, without harvesting other cartilage.

A new method of urethroplasty for prevention of fistula in female-to-male gender reassignment surgery.

One of the primary goals of the phalloplasty for female-to-male transsexuals is to gain the voiding ability in the standing position. However, achieving the competence of urethra, sensation and rigidity of the neophallus is still a significant challenge. Serious complications such as urethral fistula, obstruction and stricture were encountered in this surgery. In experienced hands, this seems to be associated with urethroplasty technique. The authors performed phalloplasty with radial forearm osteocutaneous free flap method in 70 patients of female-to-male transsexuals. In 38 cases which were enrolled before 2001, we had carried out the urethroplasty by our own method, but since 2001, we have applied the modified method of urethroplasty to reduce the incidence of urethrocutaneous fistula. Thirty-four cases have undergone a new modified method of ours. For construction of the urethra, an anteriorly based vaginal wall flap and labium minoral flaps were used in this technique. In our new method series, 1 case (1.4%) of flap loss occurred after phalloplasty. The incidence of urethrocutaneous fistula was 30%. Before the year 2001, of 38 patients, there were 14 cases (36.8%) who developed urethrocutaneous fistula. On the other hand, 7 of 32 patients (21.9%) who underwent urethroplasty by the modified labium minoral flap and anteriorly based vaginal flap had urethrocutaneous fistula after 2001. One-stage total phalloplasty and urethroplasty is associated with a significant increase of urethral fistula and obstruction. However, the urethrocutaneous fistula at the level of the female external urethral orifice can be successfully reduced using this new method.

Epidermoid cyst in temple area with skull perforation.

Epidermoid cysts are benign tumors that account for approximately 1% of intracranial tumors. In very rare cases, temporally located extradural intradiploic epidermoid cysts can cause neurological symptoms and skull perforation. Herein, we report the case of a 34-year-old woman who underwent successful treatment of an epidermoid cyst in the temporal region accompanied by neurological symptoms. Accurate radiological evaluation and complete removal of the tumor and capsule play a vital role in ensuring favorable long-term outcomes. Computed tomography and magnetic resonance imaging scans can provide an accurate assessment of the extent of intracranial expansion and invasion of the cerebral parenchyma, as well as enabling the precise localization and characterization of the bone defect and mass. In addition, collaborative surgery with a neurosurgeon is required for cases involving intracranial expansion and dural invasion.

Schwannoma on the nasal dorsum and tip with sensory changes.

Schwannomas, which originate from Schwann cells in the peripheral nervous system, are slowgrowing and uncommon benign tumors. Most schwannomas (90%) occur in isolation, and multiple occurrences are a characteristic feature of neurofibromas. Schwannomas of the nose and nasal tip are particularly unusual. Although a few cases of schwannomas of the sinusoidal tract and nasal septum have been reported, schwannomas arising from the nasal dorsum area and tip are extremely rare. Sensory abnormalities are also a very rare symptom. We excised a schwannoma on the nasal dorsum through direct incision and a schwannoma on the nasal tip through open rhinoplasty. No postoperative complications involving recurrence, hematoma, or infection occurred. The possibility of neurological changes should be considered in cases of an abnormality in the peripheral nervous system. Schwannoma must be kept in mind as a possible cause of neurological changes localized to a specific dermatome, and should always be considered in the differential diagnosis of a mass on the nose.
