BACKGROUND: Secondary reduction mammaplasty poses challenges.
OBJECTIVE: This article delves into the reasons and complaints regarding secondary repair following double-ring method and outlines the principle and logic of utilizing vertical incision for repair.
METHODS: A retrospective analysis of patients who underwent secondary reduction mammaplasty in our hospital was conducted. The analysis included baseline demographic data, reasons for consultation, surgical records, and postoperative outcomes.
RESULTS: Thirty-five patients (70 breasts) underwent secondary reduction mammaplasty. The mean time between the primary reduction mammaplasty and second procedure was 2.99 years (range, 0.5-15years). The mean weights were 210.49g (range, 42-558g) and 207.91g (range, 6-560g) for left and right mastectomies, respectively. Reasons for secondary reduction mammaplasty include poor shape (flat breasts and pseudoptosis), widened incision scar, persistent macromastia, and bilateral asymmetry.
CONCLUSIONS: The superior and superomedial vertical techniques are safe, effective, and satisfactory in secondary reduction mammaplasty.

BACKGROUND: Intrabony defects beneath non-keratinized mucosa are frequently observed at the distal site of terminal molars. Consequently, the application of regenerative treatment using the modified wedge-flap technique is considered impractical for these specific dental conditions.
METHODS: This article proposes a modified surgical procedure aimed at exposing the distal intrabony defect by making a vertical incision in the keratinized buccal gingiva. The primary objective is to maintain gingival flap stability, thereby facilitating periodontal regeneration. The described technique was successfully employed in a case involving the left mandibular second molar, which presented with an intrabony defect without keratinized gingiva at the distal site. In this case, an incision was made on the disto-buccal gingival tissue, creating a tunnel-like separation of the distal non-keratinized soft tissue to expose the intrabony defect. Subsequently, bone grafting and guided tissue regeneration surgeries were performed, resulting in satisfactory bone fill at 9 mo postoperatively.
CONCLUSIONS: This technique offers a regenerative opportunity for the intrabony defects beneath non-keratinized mucosa and is recommended for further research.

BACKGROUND: Vertical mammoplasty techniques have been widely used for breast reduction. The authors present the combination of superior pedicle vertical mammoplasty with liposuction in different regions in the treatment of severe breast hypertrophy in obese patients. We also propose some innovative methods in terms of surgical approach, breast parenchymal anatomy pattern and liposuction.
METHODS: A retrospective study of 50 female patients with severe hypertrophic breasts and obesity who underwent breast reduction in our department from February 2019 to February 2022 was performed. Pre- and postoperative photographs, breast parenchyma distribution and postoperative patient satisfaction were recorded.
RESULTS: Fifty patients underwent breast reduction. Through clinical examination, patient photo evaluation and satisfaction survey results. Good breast shape and projection, full upper pole of the breast, and high satisfaction results were obtained. There were no serious complications.
CONCLUSIONS: This technique is acceptable and reproducible. It is suitable for patients with varying degrees of breast hypertrophy, especially those with severe hypertrophic breasts and obesity. There are fewer associated complications and a lower rate of re-repair.

UNASSIGNED: The infrapatellar branch of saphenous nerve (IPBSN) has anatomic variations and prone to injury during surgery around the medial side of the knee. High tibial osteotomy is one of the procedures that may be risky to the IPBSN. This research was aimed to establish which skin incision (vertical vs oblique) is less likely to damage to the IPBSN and also to study the anatomy of the IPBSN, with the institutional review board reference (No. LH611054, date 10/1/2020). The primary outcomes are aimed to establish which skin incision (vertical vs oblique) is less damaging to the IPBSN. The secondary outcome is to study about the anatomy of the IPBSN.
UNASSIGNED: Twenty-two fresh cadavers (forty-four knees) were dissected by randomisation under the block of four technique, and two different incisions were performed for each knee. Exploration was performed from the skin incision to the IPBSN around the incision zone. If the discontinuity of the nerve was found, it was classified as IPBSN injury. The anatomic measurement was performed. The IPBSN injury between two groups were analysed with the chi-square test.
UNASSIGNED: The risk of IPBSN injury in the oblique group was 2 from 22 knees (9.1%), and 12 knees from 22 knees (54.5%) in the vertical group (P=0.001). Most common number of branch(es) found, is one branch, the horizontal distance ranged from 2.6cm to 8.5cm (average 5.7±1.6), the vertical distance ranged from 4.4cm to 12.6cm (average 7.6±1.9) and the declination angle ranged from 6° to 87° (average 34.7±24.3).
UNASSIGNED: The risk of the IPBSN injury in oblique skin incision may be less than the vertical incision in the medial opening wedge HTO.

UNASSIGNED: The aim of this article is to explore the risk of incisional hernia (IH) occurrence at the site of specimen extraction following laparoscopic colorectal resection (LCR), highlighting the comparison between transverse incision versus midline vertical abdominal incision.
UNASSIGNED: Analysis was conducted according to PRISMA guidelines. Systematic search of medical databases, EMBASE, MEDLINE, PubMed and Cochrane Library were performed to find all types of comparative studies reporting the incidence of IH at the specimen extraction site of transverse or vertical midline incision following LCR. The analysis of the pooled data was done using the RevMan statistical software.
UNASSIGNED: Twenty-five comparative studies (including 2 randomised controlled trials) on 10,362 patients fulfilled the inclusion criteria. There were 4,944 patients in the transverse incision group and 5,418 patients in the vertical midline incision group. In the random effects model analysis, the use of transverse incision for specimen extraction following LCR reduced the risk of IH development (odds ratio =0.30, 95% CI: 0.19-0.49, Z=4.88, P=0.00001). However, there was significant heterogeneity (Tau2=0.97; Chi2=109.98, df=24, P=0.00004; I2=78%) among included studies. The limitation of the study is due to lack of RCTs, this study includes both prospective and retrospective studies along with 2 RCTs which makes the meta-analysis potentially biased in source of evidence.
UNASSIGNED: Transverse incision used for specimen extraction following LCR seems to reduce the risk of postoperative IH incidence compared to vertical midline abdominal incisions.

BACKGROUND: The traditional approach for occipital migraine surgery encompasses three separate surgical incisions in the posterior neck to decompress the greater occipital nerves (GON), lesser occipital nerves (LON), and third occipital nerves (TON). Other incisions have been investigated, including singular transverse incisions. We sought to evaluate a single, vertical midline incision approach for decompression of all six occipital nerves.
METHODS: Using 10 cadaveric hemi-sides (5 fresh cadaver head and necks). Anatomic landmarks and the location of the bilateral GON, LON, and TON were marked according to previous anatomic studies. A single, midline 9-cm incision was made, and lateral skin flaps were raised to decompress or avulse all six nerves.
RESULTS: Through the midline incision, the GON and TON were identified at 3.5 and 6.2 cm, respectively, inferior to a line bisecting the external auditory canal (EAC) and 1.5 cm lateral to the midline. The LON was identified as 6-cm inferior and 6.5-cm medial to a line bisecting the EAC in the plane just above the investing layer of the deep cervical fascia until the posterior border of the sternocleidomastoid was encountered. The LON had the greatest amount of variation but was identified lateral to the posterior border of the SCM.
CONCLUSIONS: A single midline incision approach allows for successful identification and decompression of all six occipital nerves in migraine surgery.

UNASSIGNED: Injury to the inferior branch of the saphenous nerve (IBSN) and the subsequent loss of skin sensation after anterior cruciate ligament (ACL) reconstruction are common. The literature suggests that the incision angle may affect the incidence and area of loss of skin sensation.
UNASSIGNED: To determine whether there is a difference in the incidence and area of altered sensory loss on the tibia between vertical (VI) and oblique (OI) incisions for semitendinosus-gracilis tendon graft harvest during ACL reconstruction. The cadaveric component was designed to determine whether there is a \"safe zone\" for incision by identifying the location and number of branches of the IBSN.
UNASSIGNED: Randomized controlled trial; Level of evidence, 2.
UNASSIGNED: Patients (n = 37) were randomized to receive either VI or OI. Incidence and area of altered skin sensation were documented during at least 1 postoperative visit. In addition, 18 cadaveric knees were dissected.
UNASSIGNED: The presence or absence of hypoesthesia did not differ between groups postoperatively. Although no statistical differences between groups were seen in the total area of perceived altered skin sensation at 3 (P = .57), 6 (P = .08), 12 (P = .65), and 24 months (P = .27), data demonstrated a trend toward VI participants having a larger area of hypoesthesia at every time point. Among the 18 cadaveric specimens, 4 variations in the distribution of IBSN were noted: 18 (100%) had 1 branch, 14 (78%) had 2 branches, 6 (33%) had 3 branches, and 1 (6%) had 4 branches. No safe zone for incision could be identified.
UNASSIGNED: No difference was found between a vertical and an oblique incision with respect to incidence or area of sensory loss. Furthermore, it was not possible to identify a safe zone that would prevent transection of all nerves branches of the IBSN based on the cadaveric component of this study.

OBJECTIVE: To compare the incidence, extent of sensory loss, its clinical effect and natural course caused by sensory nerve injury, during two different skin incisions used for autogenous hamstring graft harvest during ACL reconstruction.
METHODS: This randomized prospective study was carried out on 84 patients, divided into two groups, all of them underwent arthroscopic ACL reconstruction using hamstring tendon graft with two incisions; a vertical incision used in 43 patients, and an oblique incision in 41 patients. The location and area of sensory loss were evaluated during follow-up as well as the degree of improvement and patient satisfaction.
RESULTS: The average age in this study was 29.8 ± 7.2 in the vertical group and 29.9 ± 6.3 in the oblique group. Both semitendinosus and gracilles were harvested in 34 patients, semitendinosus in 49 patients and gracilles in one patient. In the vertical group, a higher incidence of sensory loss was recorded with 21 patients (51.2%), relative to the oblique group with 18 patients (41.9%). However, there was no statistically significant difference (p = n.s). Most of the sensory loss affected the distribution of the IPBSN (infrapatellar branch of saphenous nerve) in 27 patients (69.2%) in both groups, and to a lesser extent in the lower medial area [distribution of SBSN (sartorial branch of saphenous nerve)] in 12 patients (30.8%).
CONCLUSIONS: This study clearly revealed the high incidence of nerve injury particularly the IPBSN during hamstring graft harvest, but did not prove a difference between oblique and vertical incisions, with regard to postoperative sensory loss. It was clear that harvesting the semitendinosus alone is not a factor that can diminish nerve injury.
METHODS: II.

Objective:  To study clinical outcomes for different uterine wall incision directions, comparing vertical incision and transverse incision in laparoscopic myomectomy of the intramural myoma. Methods:  Laparoscopic myomectomies were performed on 50 women with intramural myomas. Using a table of random numbers, they were randomly divided into a vertical incision group (25 women) and a transverse incision group (25 women) according to the direction of incisions in the uterine wall. The numbers of enucleated myoma, operation duration, amount of bleeding, and numbers of sutures were compared. The Mann-Whitney U-test was used for analysis. Results:  For the transverse incision group, the amount of bleeding (137.6 ± 88.1 mL) was a significantly lower value (P = 0.0426) than for the vertical incision group (235.8 ± 169.4 mL). In addition, in cases where the maximum myoma nucleus diameter was 7 cm or larger, operation duration (129.0 ± 32.5 min) and amount of bleeding (158.9 ± 87.1 mL) showed significantly lower values (P = 0.0067 and P = 0.0002, respectively) for the transverse incision group than did operation duration (362.3 ± 147.3 min) and amount of bleeding (362.3 ± 147.3 mL) for the vertical incision group. Conclusion:  Transverse incision of the uterine wall is useful to reduce the amount of bleeding in the laparoscopic myomectomy of the intramural myoma. Transverse incision also shortens operation duration in cases where the myoma nuclei are large. (Reprod Med Biol 2004; 3: 33-37).

Common treatment for buccal gingival recession caused by an aberrant frenal attachment includes elimination of the frenum and treatment of the gingival recession by soft tissue graft to increase the width of the attached gingiva that in turn results in root coverage. Keratinised gingival, if present in adequate amount, maintains the gingival health by protecting the marginal gingiva. This not only considers the desires of the patient but also explores the potential regenerative capacity of the tissues. This report describes a novel single-stage procedure for increasing the width of the attached gingiva and eliminating the aberrant frenal attachment.
