Dermatofibrosarcoma protuberans(DFSP) is an uncommon recurrent soft-tumor of skin and is locally highly invasive and aggressive, although it rarely metastasizes. When possible, of the many treatment modalities, the surgical excision is indicated primarily. There are three surgical modalities, which are excision with undefined or conservative surgical margins, excision with wide surgical margins and Mohs micrographic surgery(MMS). And the classical standard surgery was the local wide excision with at least 3cm margin around the primary tumor and through the deep fascia. However recent studies has showed that MMS decreased the recurrent rate of the tumor, conserving the normal uninvolved tissue, and MMS is accepted as the first choice treatment modality of DFSP. Some studies reported that the margin of 2.5cm is necessary to clear the tumor in MMS. We present two cases of recurrent DFSP treated by Mohs micrographic surgery, one through 4-staged resection, the other, 3-staged resection of the tumor.

The paper summarizes the academic thought and clinical experience of professor LI De-hua in treatment of facial nerve injury after total parotidectomy with blade needle based on jingjin (muscle region of meridian, sinew/fascia) theory. This disease is located at muscle regions of hand-/foot-three yang meridians; and the sinew/fascia adhesion is its basic pathogenesis, manifested by "transversely-distributed collaterals" and "knotted tendons". In treatment, the knotted tendons are taken as the points. Using the relaxation technique of blade needle, the lesions of sinews/fascia are dissected and removed to release the stimulation or compression to the nerves and vessels so that the normal function of sinews/fascia can be restored.

Understanding of a variety of membranous structures throughout the body,such as the fascia,the serous membrane,is of great importance to surgeons. This is especially valuable in abdominal surgery. With the rise of membrane theory in recent years,membrane anatomy has been widely recognized in the treatment of abdominal tumors,especially of gastrointestinal tumors. In clinical practice. The appropriate choice of intramembranous or extramembranous anatomy is appropriate to achieve precision surgery. Based on the current research results,this article described the application of membrane anatomy in the field of hepatobiliary surgery,pancreatic surgery,and splenic surgery,with the aim of blazed the path from modest beginnings.

PURPOSE: In Asians, nasal dorsal and tip augmentation procedures are usually performed at the same time, and most dorsal augmentations use implants. In this study, dorsal augmentation was given by various types of grafts using deep temporal fascia (DTF) for primary rhinoplasty cases using only autologous tissues to improve the curve of hump noses and depressions. For secondary rhinoplasty cases, DTF was used to improve implant demarcation and transparency. Such effectiveness and utility of DTF is discussed. MATERIALS AND METHODS: Between May 2009 and May 2012, we performed rhinoplasty using DTF in 175 patients, which included 78 secondary surgery patients and 128 female patients. The mean age of the patients was 31.4. DTF was utilized with various types of grafts without implants to improve the curve in dorsal augmentation of hump noses and cases that required curve betterment. DTF was used to improve implant demarcation and transparency for secondary cases. RESULTS: The mean follow-up duration was 1.5 years. Of the 175 patients, 81% were satisfied with the natural correction achieved, whereas 19% complained of undercorrection, which was resolved with additional surgery. No specific complications such as nasal inflammation or contractures were observed. CONCLUSION: DTF can be used with various graft methods for correction of radix, dorsal, and tip irregularities. It can also be used to correct implant contour transparency in secondary rhinoplasty and thus may be considered as a useful supplementary graft material in rhinoplasty for Asians.

Total mesorectal excision (TME) is the gold standard of surgical treatment for mid and low rectal cancer. It aims to improve the oncological outcomes as well as preserve anal sphincter, sexual and urinary function. Compared with sympathetic nerve injury alone, pelvic plexus and neurovascular bundle (NVB) injury has significant effect on postoperative sexual dysfunction, especially erectile function. Since the lateral surgical plane of TME is narrow and densely packed, dissecting outside the plane causes pelvic plexus injury, while dissecting inside it results in residual mesorectum. In this commentary, we review the research progress of lateral fascial anatomy of TME, and describe the anatomical characteristics of rectosacral fascia based on our previous research results. The prehypogastric fascia acts as a "fascia barrier" when dissecting the lateral space constantly from posterior to anterior. In addition, the pelvic plexus fuses with the prehypogastric fascia which is considered as the outer side layer of rectosacral fascia laterally. Thus, the rectosacral fascia should be dissected at the level of S4 vertebral body posterior to the rectum in an arc shape and then enter the superior-levator space. Before dissecting the lateral spaces, the anterior space of the rectum should be dissected first. After an "U" shape cutting of the Denonvilliers' fascia, the lateral space should be dissected from anterior to posterior. Finally, the lateral attachment of rectosacral fascia is transected to ensure the integrity of the mesorectum without damaging the pelvic plexus.

Objective: To investigate the anatomic characteristics of the right retroperitoneal fascia and its surgical implementation while performing complete mesocolic excision (CME) for right colon cancer. Methods: A descriptive study was carried out. (1) Clinicopathological data and surgical videos of 17 non-consecutive patients undergoing laparoscopic right hemicolectomy (extended right hemicolectomy) with CME for right colon cancer at Department of Colorectal Surgery of Union Hospital, Fujian Medical University between January 2020 and October 2020 were retrospectively collected. The construction of right retroperitoneal fascia was observed from caudal dorsal direction and caudal ventral direction. (2) Three postoperative specimens from 3 cases undergoing laparoscopic right hemicolectomy with CME for right colon cancer in June 2020 were prospectively included to observe anatomy and examine histology. (3) Five abdominal cadaver specimens from the Department of Anatomy of Fujian Medical University were enrolled, including 3 males and 2 females. Anatomical observation and histological studies were performed from the cranial approach and the caudal dorsal approach. Masson staining was used to examine the histology. Results: (1) Surgical video observation: The typical structure of right retroperitoneal fascia could be observed in all the 17 patients. The fascia was a rigid barrier between the posterior space of the ascending colon and the anterior pancreaticoduodenal space behind the transverse colon. The right retroperitoneal fascia should be sharply cut to communicate between the two spaces to avoid entering the right mesocolon by mistake. The severed ventral stump of the right retroperitoneal fascia ran along the dorsal side of the right hemicolon to the lateral side, and the dorsal stump covered the level of the duodenum caudally, and continued to move downward, covering the surface of Gerota's fascia. (2) Observation of 3 surgical specimens: The dorsal side of the right mesocolon was smooth and intact, which could be anchored in the corresponding area of the lateral edge of the duodenum. The ventral stump of the right retroperitoneal fascia could be seen, which attached to the dorsal side of the right mesocolon semi-circularly. Masson staining observation: The ventral stump of the right retroperitoneal fascia ran cephalad, fused with the dorsal side of the right mesocolon tightly and curled. The caudal side of confluence and the dorsal side of the right mesocolon presented a bilobed structure. (3) Anatomy of 5 cadaveric specimens: The right retroperitoneal fascia was a thin fascia structure, which was a rigid barrier between the anterior pancreaticoduodenal space behind the transverse colon and the posterior space of the ascending colon. The ventral stump of the right retroperitoneal fascia (including the dorsal side of the right mesocolon), the dorsal stump of the right retroperitoneal fascia (including part of the duodenal wall) and the dorsal side of the right mesocolon were retrieved for histological examination. The ventral stump of the right retroperitoneal fascia fused with the dorsal side of the right mesocolon by the cephalic side, and the dorsal side of the right hemi-mesocolon on the fusion level by caudal side gradually separated into a double-layer loose fascial structure. The dorsal stump of the right retroperitoneal fascia covered the surface of the duodenum level, moved on from the ventral side to the surface of the prerenal fascia, and continued to the caudal side. Conclusions: The right retroperitoneal fascia is a rigid barrier between the anterior pancreaticoduodenal space behind the transverse colon and the posterior space of the ascending colon. The Toldt fascia formed by fusion with the dorsal lobe of the right colon travels to the edge of the descending and horizontal part of the duodenum and separates again. The right retroperitoneal fascia is attached to the edge of the duodenum, reversing and running on the surface of the prerenal fascia, while the dorsal lobe of the right colon runs in front of the pancreas and duodenum, and shifts to the pancreaticoduodenal fascia. During the operation, this fascia should be identified and cut to penetrate the anterior pancreaticoduodenal space behind the transverse colon and the posterior ascending colon space, which helps to ensure the integrity of the dorsal side of the right hemi-mesocolon.

In 1982, total mesorectal excision(TME) was proposed by Professor R. J. Heald, which was a milestone-style for rectal cancer surgery. The concept of TME has reduced the local recurrence rate of mid-low rectal cancer (MLRC) significantly, thus becomes the gold standard for MLRC surgery. However, the incidence of urogenital dysfunction after TME remains high, among which urinary dysfunction reaches 30%-60%, and sexual dysfunction reaches 50%-70%. In recent years, studies have shown that the removal of Denonvilliers' fascia (DVF) during TME is an important cause of postoperative urination and sexual dysfunction. Therefore, DVF preserving total mesorectal excision (iTME) has been recognized by more and more surgical experts. On the basis of existing literature and clinical practice, we organize experts to discuss and vote, put forward recommendations for several issues of iTME, and finally formulate this expert consensus. The formulation of this consensus aims to increase surgeons' awareness of the value and functional protection of DVF during TME surgery, clarify the indications and contraindications of iTME, and standardize the procedure of iTME, so as to reduce postoperative urination and sexual dysfunction and improve the quality of life of patients with MLRC. The level of evidence and recommendation of this consensus is determined by Grading Recommendations, Assessment, Development and Evaluation (GRADE), and the consensus content is determined through expert voting and Delphi method.

OBJECTIVE: To explore the technique of "two-flap" in ear reconstruction. METHOD: Quantitative tissue expansions were used in the mastoid area in the first stage. After the final injection, there was 1 month of sustaining time. Expanded skin flap and unexpanded fascia flap were designed in the second stage, so the "two-flap" technique was used in the ear reconstruction. From January 2004 to December 2008, 1427 patients of microtia were treated using "two-flap" technique. RESULT: The expanded skin flap could show the fine structures of the reconstructed ears. The reconstructed ears had vivid cranioauricular angle after using the unexpanded fascia flap. CONCLUSION "Two-flap" method was easily manipulated and the complications were rare. The reconstructed ears had lucid and three-dimensional contour.
