“…There are three types of tissue expanders: standard round, rectangular, and crescent, of which the rectangular shape is the most effective. Rectangular expanders gain about 38% tissue area of the calculated surface increase of the expander, whereas round type expanders gain 25% of the calculated surface increase [23]. We used the rectangular self-inflating tissue expander which was composed of methyl methacrylate and 1-vinyl-2-pyrrolidone enclosed with a silicone envelope.…”

Objectives: The purpose of this study was to evaluate the effectiveness of the intraoral use of subperiosteally placed self-inflating tissue expanders for subsequent bone augmentation and implant integrity. Material and methods: A prospective, multicenter, randomized controlled trial was performed on patients requiring alveolar bone graft for dental implant insertion. Patients were assigned to three groups: tissue expansion and tunneling graft (TET group), tissue expansion and conventional bone graft (TEG), and control group without tissue expansion. Dimensional changes of soft tissue and radiographic vertical bone gain, retention, and peri-implant marginal bone changes were evaluated and secondary outcomes; clinical complications and thickness changes of expanded overlying tissue were assessed. Results: Among 75 patients screened, a total of 57 patients were included in the final analysis. Most patients showed uneventful soft tissue expansion without any inflammatory sign or symptoms. Ultrasonographic measurements of overlying gingiva revealed no thinning after tissue expansion (p > 0.05). Mean soft vertical and horizontal tissue measurements at the end of its expansion were 5.62 and 6.03 mm, respectively. Significantly higher vertical bone gain was shown in the TEG (5.71 ± 1.99 mm) compared with that in the control patients (4.32 ± 0.97 mm; p < 0.05). Hard tissue retention— measured by bone resorption after 6 months—showed that control group showed higher amount of vertical (2.06 ± 1.00 mm) and horizontal bone resorption (1.69 ± 0.81 mm) compared to that of the TEG group (p < 0.05). Conclusion: The self-inflating tissue expander effectively augmented soft tissue volume and both conventional bone graft and tunneling techniques confirmed their effectiveness in bone augmentation. With greater amount of bone gain and better 6 month hard tissue integrity, the TEG group compared to the control group—without tissue expansion—showed that the combined modality of tissue expander use and guided bone regeneration (GBR) technique may improve the outcome and predictability of hard tissue augmentation.

“…As the expansion procedure progresses, there is an increase in the number and caliber of the random and axial pattern vessel present within the flap which leads to the increase in blood flow to the extended flaps, ultimately leading to very negligible chances of ischemic necrosis of the flap.

Nowadays, cutaneous expansion is used progressively in reconstructive surgery for treating the variety of problems such as burns alopecia scar revision in children and adults. With the use of tissue expansion technique, the reconstruction of many acquired and congenital defects has been made possible. Tissue expanders are principally based on the mechanical and the biological creep in which mechanical creep is the morphological changes occurring in cellular level in response to applied stress and biological creep is the resultant expansion of skin surface. There is an excellent closure of extensive soft tissue defects without additional scars in donor area with tissue expanders as compared with other methods of plastic surgery the case report highlights the excellent results of tissue expander in an esthetically compromised patient due to hypotrophic scar on the forehead. This is a novel technique as it was performed under local anesthesia without the use of any sedation in a regular clinical setup.

“…Skin from expanded tissue is sensate and has the same texture and color as the original skin, which provides a functionally and cosmetically appealing result. 15 Furthermore, given that insensate skin can lead to abrasion with footwear resulting in pressure sores and wound complications, tissue expansion offers a significant advantage. 8,16,17 Nevertheless, the use of soft tissue expanders requires the patient and surgeon commitment to staged surgery.…”
