BACKGROUND: The medial arm flap (MAF) has been used as a pedicle flap and free flap to reconstruct various deformities, including those of the head and neck, axilla, elbow, chest, and hand. This study reviews the anatomy of the flap, the technique of flap harvest, its clinical applications, and a systematic review of the current published literature.
METHODS: An online systematic review of MEDLINE, EMBASE, PubMed, and The Cochrane Library from inception to September 30, 2023, was completed. Studies that investigate the anatomy, technique or clinical outcomes of medial arm flaps were included. Clinical data extracted includes patient, defect, flap characteristics, complications, and take-back procedures. Anatomic data extracted includes anatomical variations, and vascular characteristics and patterns.
RESULTS: Between 1980 and 2023, 50 papers were published outlining the medial arm flap. Anatomic studies detail the anatomy of 384 medial arms, and outcomes are reported for 283 MAFs (75 free flaps and 208 pedicle flaps). The superior ulnar collateral artery is most commonly cited as the dominant arterial supply to the middle third of the medial arm. The majority of patients required reconstruction post-burn (39.2%), trauma (17.7%), and tumor excision (12.4%). MAFs were mostly used to reconstruct defects of the head and neck (41.7%), the hand and wrist (21.9%), and the elbow (16.3%). Eleven flaps (4.1%) suffered partial flap failure, and two flaps (0.7%) suffered total flap failure.
CONCLUSIONS: This manuscript demonstrates that the MAF is a reliable and underutilized flap option with a well-hidden donor scar and a low complication rate.

A systematic treatment plan and an appropriate selection of surgical technique are the critical requirements for an effective closure of oroantral fistula (OAF). A 45-year-old female patient had sinus opening after she underwent a surgical tooth extraction 20 years back. On her frequent visits to the dentists some attempts were made for closure including surgical intervention, only for the lesion to return back. Computerized tomography (CT) scan was taken to rule out any bony extension of a lesion, the CT revealed a 1 × 1 cm radiolucency with a through - through communication from the alveolar bone to the right maxillary sinus because of the bony defect in the floor of maxillary sinus along with thickening of the maxillary sinus lining. The closure of the defect was done by a lateral pedicle flap raised from the right side was elevated and laterally slid to cover the defect without tension and was sutured with 4-0 resorbable interrupted suture while maintaining a bare surgical bed covered by the periosteum and a thin layer of connective tissue. This technique provides immediate repair of the defect to the patient, and also maintains comparatively normal anatomic architecture to the oral cavity. Eight months postoperative follow-up revealed a complete closure of OAF without any complications. The findings of this case suggest that lateral sliding pedicle flap can be a conservative approach in managing a long-standing OAF.

OBJECTIVE: To evaluate appendiceal onlay flap ureteroplasty for repairing complex right proximal and mid-ureteric strictures.
METHODS: Between August 2006 and August 2012 four women and two men (mean age 34.2 years) underwent right laparoscopic appendiceal onlay flap ureteroplasty. The mean stricture length was 2.5 cm. Stricture formation was secondary to impacted ureteric stones in three patients and failed pyeloplasty for congenital pelvi-ureteric junction obstruction in the remaining three. Each patient had ipsilateral flank pain before surgery.
RESULTS: The mean operating time, estimated blood loss and hospital stay were 244 min, 175 mL and 3.2 days, respectively. No intra- or peri-operative complications were noted. The objective success rate was 100% (all patients had radiographic and/or endoscopic resolution of their ureteric strictures). The subjective success rate was 66%, (two patients developed recurrent discomfort, which upon exploration was found to be attributable to fibrosis away from the appendiceal onlay graft, where the gonadal vessels crossed the ureter). Both patients with recurrent pain underwent laparoscopic ureterolysis and bladder advancement flap proximal to the appendiceal onlay, which markedly improved one patient\'s pain but the other patient continued to have discomfort, ultimately resulting in a laparoscopic nephroureterectomy.
CONCLUSIONS: Appendiceal onlay ureteroplasty is a viable treatment option for patients with complex right proximal and mid-ureteric strictures, while minimising the potential morbidity of appendiceal and ileal interposition.
