Objective: To provide anatomic evidence for identification of "holy plane" between fascia propria and its adjacent fascia in total mesorectal excision.
Methods: A total of 26 pelvic specimens of adult male preserved in 10% formalin solution were used in this study. Twenty pelvis were employed for topographic anatomy, six for sectional anatomy.
Results: Rectovesical septum was formed by the ventral part of the fascia propria and Denonvilliers' fascia, with no blood vessel and nerve coursed between two layers. Dorsal part of the fascia propria parallelled with the presacral fascia, with no blood vessel and nerve coursed between two layers in 80% of the pelvis. However, anatomic variations was encountered occasionally--with muscle-like tissue or fusion of presacral fascia interposed between them for 20%. The lateral space of rectum was between lateral part of the fascia propria and parietal fascia which witnessed pelvic nerve plexus and lateral ligament of the rectum traveling. Pelvic nerve plexus was categorized as two types according the relation between fascia propria and nerve plexus: fusion type accounting for 85% and rarefaction type for 15%.
Conclusion: 'holy plane' is sandwiched between the fascia propria and its adjacent fascia--ventrally Denonvilliers fascia, dorsally presacral fascia and laterally parietal fascia.

Objective: To review the various basic research and treatments available to regenerate the vocal folds and to discuss the direction for future treatments.
Methods: A comprehensive review was performed in PubMed database and Google Scholar utilizing search terms including combinations and variations of the following concepts: vocal fold anatomy, vocal fold disorders, and regenerative therapies. No particular inclusion or exclusion criteria were set due to the nature of this narrative review article.

Objective: The objective of this study is to report the technical nuances of glans wings creation in anatomical plane facilitating liberal glans wings mobilization with preservation of glanular vessels for tension-free glansplasty in surgery of hypospadias in primary and redo cases.
Materials And Methods: Eighty-six primary hyposapdias and 7 cases of distal hypospadias, operated elsewhere and presented with glans and urethroplasty dehiscence, undergoing tubularized-incised-plate (TIP) repair were included after ethical approval. Technical points of glans wings creation in the subfascial plane included (i) creation of Buck's fascia window, just proximal and lateral to the point of bifurcation of corpus spongiosum, (ii) creation of subfascial-pret unical plane on the tunica albuginea of corpora cavernosa up to ventral limit of laid open glanular meatus, (iii) release of pillars of corpus spongiosum off the glans base keeping the basal lamina propria covering the vascular arcade intact, (iv) release of glans base off the tip of corpora cavernosa and composite flap of corpus spongiosum pillars with Buck's fascia off the corpora cavernosa, (v) approximation of glans wings over the tubularized-incised-plate covered with dartos, and (vi) approximation of fasciospongioplasty flaps at hypospadiac meatus.

Background: Total mesorectal excision along the "holy plane" is the only radical surgery for rectal cancer, regardless of tumor size, localization or even tumor stage. However, according to the concept of membrane anatomy, multiple fascial spaces around the rectum could be used as the surgical plane to achieve radical resection.
Aim: To propose a new membrane anatomical and staging-oriented classification system for tailoring the radicality during rectal cancer surgery.
Introduction: Multidisciplinary management of patients with rectal cancer presents a gold standard of care; neoadjuvant therapy indications are based on magnetic resonance imaging (MRI) description of the local stage of the carcinoma. Although the accuracy of MRI-based assessment of cancer depth of invasion is satisfactory, its accuracy in the assessment of mesorectal lymphadenopathy is very questionable.
Methods: This was a prospective, single-centre, cohort study focused on the accuracy of preoperative MRI in the assessment of mesorectal lymph nodes (LN).
