inverted nipple may cause various cosmetic , psychological , breast feeding and hygienic problems . providing a symmetrical nipple shape and position with permanent projection nonsurgical treatments include breast shells , breast pumps and syringe techniques . however , the beneficial and permanent effects of these treatments are controversial . in the teimourian technique which is the one of the most commonly used surgical technique , all the lactiferous ducts are cut and the dermal flaps are used as supportive bulk under the nipple for correcting moderate and severe nipple inversion . in the present study , we aimed to make a new modification of the teimourian method . after the release of the nipples , the flaps were tunnelised beneath the nipple and the tip of each flap was fixed to the nipple base in reverse s - shaped design . the modified design of the traditional triangular dermal flap procedure provides much more suspension effect as well as filling dead space under the nipple . it represents simple and reliable surgical technique to avoid the recurrence of inversion and to provide satisfying shape and projection of the nipple with minimal scar . three nipples of two female patients treated with the reverse s - shaped fixation method are presented . according to the criteria of han and hong , the nipples were classified as grades 2 and 3 [ figure 1 ] . ( b ) preoperative view of the unilateral case the operation was performed under local anaesthesia . two opposite linear incisions at 3 and 9 oclock on the two sides of the everted nipple were made within the range of the areola . afterwards , the areolar skin was dissected and the epidermis was separated from the dermis over the planned flap area . the base width of the flaps was determined as equal to radius of the nipple . on the two sides of the triangles with no epithelium , the incisions were deepened into the subcutaneous fatty tissue . on the two sides of the triangles with no epithelium , two conic shape areolar dermal flaps were created the retracting ducts and fibrous bands beneath the nipple were released with blunt dissection . if the nipple was still not free after these dissections , all the retracting ducts were transected so as not to restrict the nipple . the conic shape triangular flaps on both sides of the inverted nipple were turned down and advanced through the tunnel beneath the nipple as the filling tissue for the dead space [ figure 3 ] . the tip of each flap was sutured to the nipple base where any incision was not made at 6 and 12 oclock , also next to the base itself in reverse s shape [ figure 4 ] . because the length of the flap is shorter than the diameter of the areolar external circle , the fixations of the flaps provided a strongly suspending effect and the flaps was completely able to fill out the dead space beneath the nipple . any complication was not observed and the patients recovered uneventfully during the follow - up period . the conic - shape triangular flaps on both sides of the inverted nipple were turned down and advanced through the tunnel beneath the nipple as the filling tissue for the dead space the tip of each flap was sutured to the nipple base where any incision was not made at 6 and 12 oclock , also next to the base itself in reverse s shape early postoperative view of the patient three nipples of two female patients treated with the reverse s - shaped fixation method are presented . according to the criteria of han and hong , the nipples were classified as grades 2 and 3 [ figure 1 ] . ( b ) preoperative view of the unilateral case the operation was performed under local anaesthesia . two opposite linear incisions at 3 and 9 oclock on the two sides of the everted nipple were made within the range of the areola . afterwards , the areolar skin was dissected and the epidermis was separated from the dermis over the planned flap area . the base width of the flaps was determined as equal to radius of the nipple . on the two sides of the triangles with no epithelium , the incisions were deepened into the subcutaneous fatty tissue . two conic shape areolar dermal flaps on the two sides of the triangles with no epithelium , two conic shape areolar dermal flaps were created the retracting ducts and fibrous bands beneath the nipple were released with blunt dissection . if the nipple was still not free after these dissections , all the retracting ducts were transected so as not to restrict the nipple . the conic shape triangular flaps on both sides of the inverted nipple were turned down and advanced through the tunnel beneath the nipple as the filling tissue for the dead space [ figure 3 ] . the tip of each flap was sutured to the nipple base where any incision was not made at 6 and 12 oclock , also next to the base itself in reverse s shape [ figure 4 ] . because the length of the flap is shorter than the diameter of the areolar external circle , the fixations of the flaps provided a strongly suspending effect and the flaps was completely able to fill out the dead space beneath the nipple . any complication was not observed and the patients recovered uneventfully during the follow - up period . the conic - shape triangular flaps on both sides of the inverted nipple were turned down and advanced through the tunnel beneath the nipple as the filling tissue for the dead space the tip of each flap was sutured to the nipple base where any incision was not made at 6 and 12 oclock , also next to the base itself in reverse s shape early postoperative view of the patient during the postoperative follow - up period , surgical complications such as traction pain , infection , haematoma , permanent numbness , or skin necrosis were not observed . follow - up examinations were performed at 3 to 9 months ( average , 6 months ) and revealed no evidence of recurring inversion . inverted nipple can simply be defined as nipples that lie on a lower plane than the areola due to shortened lactiferous ducts embedded in short fibrous bands . the grading system by han and hong is commonly used to determine the grade of deformation . according to the grading system , in grade 2 cases , the nipples can be pulled out but can not maintain projection and have strongly tendency to go back again . blunt dissection for surgical release should be performed until the inversion does not recur without traction . the lactiferous ducts are mildly retracted and do not need to be cut for the release of fibrosis in the majority of the patients . a temporary traction suture with a suitable dressing is generally preferred after surgery for 2 weeks . in grade 3 cases , the nipple can hardly be pulled out manually due to the severe fibrosis . for correcting grade 3 cases , two or three deepithelialised dermal flaps should be used to make up for soft tissue deficiency after the release of fibrotic bands and a traction suture is also applied postoperatively . there are numerous surgical and nonsurgical techniques introduced in the literature and among these , the incision - release and local flap methods are generally used in the treatment of grades 2 and 3 nipple inversion cases . many of the flap descriptions over the last two decades are designed on the teimourian technique . in these techniques , two or three triangular flaps tunnelled and approximated below the nipple are used to fill the dead space and achieve eversion . the presented method can also be suggested as a modification of the teimourian method and the technique presented by kim et al . in this study , we introduced a new nipple suspension technique using nipple - based dermal flaps for correcting moderately and severely inverted nipples . the most significant difference of the recommended method is in its geometrical design as compared to similar surgical methods using dermal triangular flaps . in our procedure , because two triangular dermal nipple - based areolar flaps are fixed on the opposite side of the nipple base , their geometrically design was called reverse s shape . as a consequence of this design , the reverse s - shaped fixation of triangular flaps provides more traction effect to keep the nipples in protruded position after they are released . the other advantages and differences of our technique is as follows : 
 linear incision is used to create the triangular flaps on the areola , thus the scar is more uneventful and minimal;the operation time is relatively shorter because the flaps are raised without deepithelialisation;the triangular dermal flaps provide enough bulk beneath the inverted nipple;the size of the triangular flap is slightly shorter than the diameter of the areola , the flaps cause an efficiently suspending effect under the released nipple ; andthe lactiferous ducts can be preserved in grade 2 cases or if the women particularly hope to breast feeding . linear incision is used to create the triangular flaps on the areola , thus the scar is more uneventful and minimal ; the operation time is relatively shorter because the flaps are raised without deepithelialisation ; the triangular dermal flaps provide enough bulk beneath the inverted nipple ; the size of the triangular flap is slightly shorter than the diameter of the areola , the flaps cause an efficiently suspending effect under the released nipple ; and the lactiferous ducts can be preserved in grade 2 cases or if the women particularly hope to breast feeding . the technique introduced is not to be able to preserve the lactiferous tubules . however it is well - known that these functional units beneath the nipple areolar complex may already be absent in grade 2 and especially grade 3 inverted nipple cases . optimal surgical procedure in the treatment of the moderate or severe nipple inversion cases should provide a satisfying shape , sufficient projection and preserve ductal function when required . in conclusion , as an alternative nipple suspending method , the reverse s - shaped fixation method of triangular flaps is recommended to be used in any kind of nipple inversion with satisfying results and minimal scar .
