Long-patch Base Excision Repair01:02

Long-patch Base Excision Repair

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:
Base Excision Repair01:54

Base Excision Repair

One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.

Area of Science:

  • Plastic Surgery
  • Rhinoplasty Techniques

Background:

  • Alar base resection aims to narrow the nasal base and preserve nasal contour.
  • The traditional Weir wedge resection can result in unnatural nostril appearance.

Purpose of the Study:

  • To evaluate the effectiveness of the medial flap technique for alar base resection in achieving aesthetically pleasing nasal bases.
  • To compare the medial flap technique with standard methods in corrective septo-rhinoplasty.

Main Methods:

  • A retrospective review of 25 patients undergoing corrective septo-rhinoplasty.
  • Application of the medial flap technique for alar base resection in 5 selected patients.
  • Assessment of nasal base contour and nostril appearance post-operatively.

Main Results:

  • The medial flap technique resulted in normal-appearing nasal bases in all 5 patients who underwent alar base resection.
  • This technique successfully preserved or recreated normal nasal contour.
  • No adverse effects on nostril appearance were reported.

Conclusions:

  • The medial flap technique is a reliable and effective method for alar base resection.
  • It offers superior aesthetic results compared to traditional techniques, particularly in preserving natural nostril form.
  • This technique should be considered in corrective septo-rhinoplasty requiring nasal base narrowing.
