Endoscopic mucosal resection and endoscopic submucosal dissection (ESD) are operative endoscopies that have been performed since a long time. Recently, an evolution of laparoscopy called transanal minimally invasive surgery began to be popularized, and it can be adopted in the face of difficult cases for endoscopic mucosal resection/ESD. In this video, a 36-year-old woman was submitted to transanal minimally invasive surgery resection, after unsuccessful ESD, for a 2-cm polyp located anteriorly in the anal canal, just beyond the pectineal line...

Christopher M Stewart, Jonathan H Norris
The medial canthus represents one of the most challenging regions of the face to reconstruct due to the anatomical structures present, the concavity of the area, and the differences in skin texture. We present a case series of 11 patients whose defects were reconstructed with a single V-Y island pedicle flap running along the nasofacial sulcus. Our single-stage flap which modified and simplified a previously described technique achieves similar cosmetic and postoperative outcomes along with a high level of patient satisfaction in an area which can be reconstructed in a variety of ways, often with suboptimal results...

Purpose: Furcation involvement in the molars is difficult to treat, and has been recognized as a risk factor for tooth loss. Although periodontal regenerative therapies, including guided tissue regeneration and various types of bone grafts, have been applied to furcation defects, the effects of these treatments are limited, especially in large class III furcation defects. The purpose of this pilot study was to investigate the effect of reciprocal autologous root transplantation on periodontal wound healing and regeneration in class III furcation defects in dogs...

BACKGROUND: In the malar region, the SMAS flap can be thin and tear easily, making it difficult to securely fix it. And the surgical anatomy of the region may be unclear and confusing. The authors performed an anatomical study on the location of the lateral margin of the orbicularis oculi muscle (OOM) and the origin of the zygomaticus major muscle (ZMM) when using a high-SMAS facelift with finger-assisted spaces dissection technique, which included elevation of the SMAS flap with OOM...

Diploneis species have perhaps the most complex valve structure among pennate diatoms. The development of this structure was studied in D. smithii and begins with the formation of a primary band, which then develops secondary arms at both poles and the center, as in the classic Chiappino-Volcani model of raphid diatom ontogeny. Spine-like projections grow out from the primary band and secondary arms to establish the transapical ribs (virgae) of the mature valve and themselves develop spines, which are spaced first oppositely and then alternately and fuse with each other to delimit the stria pores...

This "What's new in instrumental dermatology" dedicated skin surgeryis based upon a 2015-2017 literature analysis. The excision of skin cancers is an important part of surgical dermatology. Will artificial intelligence and new drug be able to face the increasing need for therapy? Wrong-site surgery is due to multiple factors. Photographs of biopsy site and short time between biopsy and surgery decrease postponement of surgery and wrong-site surgery. Noninvasive imaging technologies are improving and help to delineate skin tumors and increase the probability of complete tumor removal...

Nose is one of the most important aesthetic unit of the face.Management of nasal trauma plays a significant role in the practices of the majority of facial and reconstructive surgeons. Replantation, although technically very challenging, is undoubtedly the procedure of choice following traumatic nasal amputation. Here we present an illustrative case report of the traumatic amputation of a nasal tip that was treated successfully with a paramedian forehead flap and further nasal reconstructive surgery. Use of the forehead flap was performed five hours after the occurrence of trauma and was followed by surgical repair about three weeks later...

BACKGROUND: Given the critical position of central glabella among the frontal, nasal, and supraorbital aesthetic subunits of the face, the reconstruction of large defects in this area represents a surgical challenge. METHODS: We describe a surgical technique based on a modified, curved, A-T flap to repair a large glabellar defect. RESULTS: Our modification is useful for large glabellar defects because it enables the distribution of the tension all over the reconstruction sides, avoiding a stressed central area and the subsequent risk of necrosis; functionally, it respects the eyebrows position and since the advancement is parallel to their major axes, it avoids the reduction of the distance between them...

Microsurgery is one of the most fertile and innovative area in reconstructive surgery. Today it is considered an indispensable technique in plastic surgery with flaps survival rates over 95% in main healthcare centers. The factors involved in achieving these results are: the improvement of the surgical technique, adequate patient selection and careful perioperative care. Perioperative care starts at the initial assessment of the patient where it's very important to consider the indications and contraindications of these procedures...

OBJECTIVE: Recently, water jet-assisted liposuction (WAL) was successfully applied by several other authors to remove fat and induce skin contraction in nonfacial body areas. Extending the range of indications for this new method, the authors of this article report on their first experience with its use in facial contouring, fat harvesting, and hydrodissection of the facial skin flap in rhytidectomy in a case series of 25 patients. METHODS: Twenty-five patients (median age: 56 years) had facelift surgery under sedation, and the WAL technique was used for facial contouring, fat harvesting for facial lipotransfer, and hydrodissection of the facial skin flap...

Background The gold standard therapy for full-thickness macular holes (FTMH) is vitrectomy (PPV) with peeling of the internal limiting membrane (ILM), gas tamponade of the vitreous cavity and postoperative face-down positioning. Nevertheless, eyes with large macular holes (> 400 µm) and surgical failures remain difficult to manage. Recently, ILM transplantation (ILM-TX) techniques were developed with acceptable results, advocating different mechanisms of hole closure: in such a setting, the ILM could serve as a scaffold for neuronal tissue in the pedicle ILM flap technique or the ILM could induce a contraction of the FTMH rims through shrinking of a folded ILM plug...

Even if human beings are the most intelligent among all living beings, they are still not immune to attack from wild animals. Human contact with bears has become more frequent as their habitat is being endangered by frequent deforestation. The sloth bear is one of the few bear species found in India, especially in the hilly areas of Southern Odisha. Bears are highly intelligent and omnivorous animals with long claws coupled with powerful shoulder. Here, we describe the tale of a poor tribal male's encounter with a sloth bear resulting in critical injuries to face, scalp, skull bone, with brain matter fungating-out of the skull...

BACKGROUND: Localized scleroderma is characterized by a thickening of the skin from excessive collagen deposits. It is not a fatal disease, but quality of life can be adversely affected due to changes in skin appearance, joint contractures, and, rarely, serious deformities of the face and extremities. We present six cases of localized scleroderma in face from our surgical practice. METHODS: We reviewed six localized scleroderma cases that were initially treated with medication and then received follow-up surgery between April 2003 and February 2015...

This paper attempted to revisit the skin lines in forehead and glabellar area.Using PubMed, Scopus, and Google, papers describing skin tension lines of face were searched. Papers with illustrations or pictures of the facial lines were selected and reviewed. The studies of the skin lines in the forehead and glabellar area were analyzed.Langer used the term "cleavage of the cutis, anatomical lines." Over the forehead, he found a border zone of horizontal folds that were interrupted many times by the ascending folds coming from the flabella area...

Although uncommon, shark attacks can lead to devastating outcomes for victims. Surgeons also face unique challenges during operative management such as exsanguination, shock, specific injury patterns and infections. This case report presents the management of a 39-year-old previously healthy female attacked by a shark while on vacation in Mexico. The patient sustained severe injuries to her left arm and her left thigh. She was transferred to a Canadian institution after ambiguous operative management in Mexico and presented with no clear antibiotic coverage and a Volkman's contracture of the left upper extremity...

Local flaps exhibit excellent color matching that no other type of flap can compete with. Moreover, surgery using a local flap is easier and faster than surgery using a distant or free flap. However, local flaps can be much more difficult to design. We designed 2 templates to plan a V-Y rotation advancement flap. The template for a unilateral V-Y rotation advancement flap was used on the face (n=5), anterior tibia (n=1), posterior axilla (n=1), ischium (n=1), and trochanter (n=2). The template for a bilateral flap was used on the sacrum (n=8), arm (n=1), and anterior tibia (n=1)...

The correction of the contour deformity after parotidectomy has become an essential procedure in the recent times for the betterment of patients' quality of life. Various modalities have been highlighted in the literature for the same. We recommend the use of posterior belly of digastric muscle flap for correction of contour deformity post excision of parotid gland tumors, subsequently ameliorating the aesthetics of the face.
