anoderm

an·o·derm

(ā'nō-derm),
Lining of the anal canal immediately inferior to the pectinate line and extending for about 1.5 cm to the anal verge; it is devoid of hair and sebaceous and sweat glands, and so is not true skin, although it is squamous epithelium; it is pale, smooth, thin, and delicate, and shiny when stretched; it is especially vulnerable to abrasion (as from coarse toilet paper) and chemical irritants (soaps), and is amply provided with tactile and nociceptive (that is, pain, itch) endings innervated by the inferior rectal (pudendal) nerve.

an·o·derm

(ā'nō-dĕrm)
Lining of the anal canal, extending from the dentate line to the anal verge; it is devoid of hair and sebaceous and sweat glands but is richly supplied with tactile and nociceptive (pain, itch) endings innervated by the inferior rectal (pudendal) nerve.

anoderm

(a'no-derm?) [ anus + derm-]
The thin, pale, shiny squamous epithelium covering the lower half (below the pectinate line) of the anal canal. This epithelium is hairless and has no glands.

It is a vertical superficial tear in anal canal just starting from anal verge and extending upward involving anoderm.
2% diltiazem or 2% nifedipine in soft white paraffin to the anoderm with finger tips or applicator after passing stools.
With the anoscope inserted, using the technique described above, multiple running sutures were placed above the dentate line, in order to avoid the anoderm and tied at the proximal end of the hemorrhoid (Figure 4).
Anal fissure is a superficial linear tear in the anoderm, most commonly caused by passage of a large, hard stool.
The procedure involves dissecting the sphincter complex from the surrounding anoderm, then overlapping the edges of the sphincter muscle and suturing them together.

It is a longitudinal split in the anoderm of the distal anal canal, which extends proximally towards but not beyond the dentate line.
The anal fissure is a small spilt in the distal anoderm, and it most commonly occurs in the posterior midline of anal canal.
Under anesthesia the open technique consists of radial incision of the anoderm over the intersphincteric groove and division of the internal sphincter under direct vision.
Excision can be accomplished by different techniques (eg, Ferguson's [closed] or Milligan-Morgan [open]) with or without closure of the anorectal mucosa or the anoderm (5)
8] Pathophysiology explains that the anoderm is more adherent to the underlying tissue in the posterior midline.
