OBJECTIVE:
To assess the feasibility, risks and advantages of endoscope-assisted second branchial cleft cyst (SBCC) resection via the retroauricular hairline approach (RHA) by comparing with conventional trans cervical approach.
METHOD:
Using prospective clinical controlled study, in twenty five patients with SBCC, 13 cases underwent endoscope-assisted resection via the RHA, 12 cases underwent conventional transcervical approach resection. Preoperatively, the sizes, locations and adjacency of all lesions were evaluated by ultrasonography, CT or MRI. Pathologic diagnoses of all cases were identified as SBCC using fine needle aspiration biopsy. Two groups were compared at length of incision, operation time, bleeding, incision cosmetic result, complication etc.
RESULT:
All 25 operations were successfully performed. Length of incision and operation time in endoscopic group were significantly longer than that of the transcervical group (P < 0.05). After three months, the mean subjective satisfaction score of incision scar in the endoscopic group was significantly higher than that of transcervical group (P < 0.01). In endoscopic group, 1 cases (7.7%) with temporary numbness of earlobe and 1 case (7.7%) with a darkened color change of the flap margin at the incision angle were found postoperatively. However, they were recovered within 1 month. All the 25 patients were disease free with a follow-up from 18 to 36 months (median follow-up: 26 months).
CONCLUSION
Endoscope-assisted SBCC resection via RHA is feasible and safe for the treatment of SBCC. In comparison with the transcervical approach, this method can provide an invisible incision and better cosmetic re suits without significant complications.

Objective To investigate the image features of congenital pyriform sinus fistula (CPSF). Methods We retrospectively analyzed the clinical features and preoperative images of 80 patients with confirmed diagnosis of CPSF by surgical and pathological outcome in Guangdong general hospital from January 2007 to December 2014. At least one of the following imaging examinations were performed for all the patients, including Barium swallow X-ray (BSX), CT and MRI. Among them, 63 patients were examined with BSX, while 42 patients underwent plain and enhanced CT scans, wherein 40 of them were exanimated shortly after BSX. Thirty-two patients underwent plain and enhanced MRI scans. Patients were divided into two groups according to their age, young age group (≤14 years old) and older age group (>14 years old). Furthermore, they were also grouped based on inflammatory or quiescent stage clinically. The images of BSX, CT, and MRI from the patients were analyzed and the positive diagnostic rates (PDR) between groups were compared by using χ2 tests. Results For the patients examined with BSX, sinuses in 35 of 63 were depicted from pyriform and fistulas in 9 of 63 were depicted from the pyriform. The overall PDR of BSX was 74.6%(47/63),wherein 46.2%(12/26)in young age group , 94.6%(35/37)in older age group, 52.9%(9/17) in inflammatory stage group ,and 82.6%(38/46)in quiescent stage group. The inter-group differences were statistically significant (χ2 were 18.911 and 5.766,both P<0.05). The PDR of CPSF with CT was 85.7%(36/42), MRI was 84.4%(27/32), BSX+CT was 87.5%(35/40). The courses of fistula or sinus were showed on CT and MRI. The presence of air bubbles at the inferomedial edge of cricothyroid joints or around the upper lobe of the thyroid gland, the changes of the morphology of thyroid grand as well as the inflammatory change along the fistula region were detected much clearly on CT and MRI. There was no statistical difference between CT and MRI groups(P>0.05).Conclusions BSX could be a screening method for suspected cases of CPSF in quiescent stage. However, the PDR could be affected by many factors (age and inflammation). CT and MRI could provide valuable information for diagnosis. An examination combined BSX and CT is preferred to improve the positive detective rate of CPSF.

OBJECTIVE:
To study the management of basic parameters related to individual piston shaping on malleostapedotomy by MDST 3D reconstruction and microanatomy and to assess the accuracy of MDST method.
METHOD:
Ten Chinese temporal bones without ear diseases were numbered randomly and scanned by GE Light Speed Ultra 64 rows of spiral CT. 3D structure of ossicular chain were reconstructed by MPR and VR methods in AW4. 1 workstation. Then measurements of distances between stapes head to stapes footplate (A line), and manubrium to stapes head (B line), and manubrium to stapes footplate (C line), angle between line A and line B (angle AB) are completed. After that, all samples of temporal bone were undergone canal wall down mastoidectomy under microscope and the relevant measurements were completed.
RESULT:
The MPR and VR technique of MDCT reconstructed ossicular chain clearly, and revealed the spatial relationship between every structure stereoscopically. Respectively, lengths of A, B, C line by MDST and microanatomy are (3.42 +/- 0.86) mm and (3.60 +/- 0.94) mm, (3.42 +/- 0.80) mm and (2.96 +/- 0.42) mm, (5.86 +/- 0.60) mm and (6.22 +/- 1.10) mm, while angle AB (141.05 +/- 30.07) degrees and (144.57 +/- 41.86) degrees. There are no statistically significant differences between two groups (P>0.05).
CONCLUSION
The MPR and VR technique of MDCT can clearly reconstructed the 3D shapes of the temporal bone and finish the exactly managements on A, B, C lines and AB angel which is crucial for shaping a individual piston on malleus-to-oval window surgery.

Extracellular matrix (ECM) components confer biomechanical properties, maintain cell phenotype and mediate tissue homeostasis. ECM remodeling is complex and plays a key role in both physiological and pathological processes. Matrix metalloproteinases (MMPs) are a group of enzymes responsible for ECM degradation and have been accepted as a key regulator in ECM remodeling. In this mini-review, we summarize MMPs categories, functions and the targeted substrates. We then discuss current understanding of the role of MMPs-mediated events, including inflammation reaction, angiogenesis, cellular activities, etc., in ECM remodeling in the context of regenerative medicine.
