ABSTRACT
Objective: To investigate the feasibility of only surgical resection for nasal vestibular squamous cell carcinoma and the efficacy of perforator flap of ipsilateral nasolabial sulcus in repairing postoperative defects. Methods: The clinical data of 8 cases with squamous cell carcinoma of the nasal vestibule who admitted to Department of Facial Plastic and Reconstructive Surgery, Eye & ENT Hospital, Fudan University were analyzed, including 6 males and 2 females, aged from 38 to 75 years. The tumor of the nasal vestibule was eradicated in time after making definite diagnosis of lesions, then the perforators flap of the ipsilateral nasolabial sulcus was used for repairment, without performing further chemotherapy or radiotherapy after surgery. The tumor recurrence, facial appearance, nostril form, donor area scar, nasal ventilation function, and cutaneous sensation were evaluated after surgery. Descriptive analysis was used in this research. Results: There were 2 cases of stage T1 and 6 cases of stage T2 in 8 cases. After 32 to 45 months of following-up, no recurrence accurred and all the flaps survived well. However, there was about 2 mm necrosis of the transplanted flap in the lateral foot of the alar in one case, which was healed well by carrying out wound care after 10 d. And the dark color flap was occurred in another case, showing the flap's backflow trouble, yet it was improved with addressing timely during 5 d postoperation. Pincusion-like deformity of the transplanted flap occurred in 4 cases (50%), which subsided gradually after 6 months. The morphology of the anterior nostril was altered in 4 cases (50%), but there was no ventilation trouble and no need for addressment in any case. The postoperative facial appearance was rated as excellentor good with hidden scar in the donor site, and the sensation of the transplanted flaps was indistinct from the surrounding tissue after 3 months. Conclusions: Surgical resection of nasal vestibular squamous cell carcinoma with tumor stage T1-2 is a feasible treatment. And it is the one of the best reconstructive methods of the perforator flap of the ipsilateral nasolabial sulcus to repair the deformities after the surgery.

<p><b>OBJECTIVE</b>To characterize the clinical and cardiac MRI features of dilated cardiomyopathy (DCM) and left ventricular noncompaction (LVNC).</p><p><b>METHODS</b>Compared the clinical and MRI features between 25 patients with LVNC and 21 patients with DCM. The MRI derived diastolic left ventricular wall thickness and the number and degree of noncompaction (NC) were evaluated using the 17-segment model.</p><p><b>RESULTS</b>Chest distress, shortness of breath and abnormal ECG were presented in all DCM patients, abnormal ECG was evidenced in 22 LVNC patients and 21 out of 25 LVNC patients presented similar clinical symptoms as DCM patients while the rest 4 LVNC patients were asymptomatic. Left atrial and ventricular dimensions were significantly smaller in LVNC patients compared to DCM patients. The degree of left ventricular (LV) spherical remodeling was significantly greater in patients with DCM (sphericity index, SI = 0.81 +/- 0.06) than in patients with LVNC (SI = 0.74 +/- 0.11, P < 0.05). The LV ejection fraction (LVEF) was significantly higher in patients with LVNC (32.7% +/- 14.2%) than that in patients with DCM (15.0% +/- 5.1%). The number of NC segments in LVNC patients (9 +/- 1) was significantly higher than the number of hypertrabeculation segment in DCM patients (5 +/- 2). The left ventricular apex (the 17th segment) was unexceptionally involved in all LVNC patients, while hypertrabeculation was absent in the 17th segment of DCM patients. The NC was more common in the apical and mid segments (16th, 12th and 11th segments) than in basal and mid septal segments (2nd, 3rd, 8th and 9th segments) in both LVNC and DCM patients. The thickness of compacted myocardium of the segments associated with noncompaction appeared thin in two groups. The wall thickness of noncompaction myocardium segments was thicker in LVNC patients than in DCM patients. The end-diastolic NC/C ratio was, on average, higher in patients with LVNC (3.3 +/- 0.6) than in patients with DCM (1.9 +/- 0.3).</p><p><b>CONCLUSIONS</b>The clinical manifestation is similar while there are significant differences in the morphology and function of left atria and left ventricle between the LVNC and DCM patients. The different distribution and degree of NC were helpful to differentiate LVNC from DCM.</p>
