RESUMO
Some cases of moderate or severe cryptotia are accompanied by a shortage of the helix. Although various operative techniques for correcting cryptotia have been reported, elongation of the helix is not considered in most of those techniques. In cases of a shortage of the helix, a drooped wide helix like a constricted ear or a cranially and posteriorly hypoplastic ear, which is characteristic of cryptotia, can appear after surgery if the helix has not been elongated. We previously reported a large Z-plasty technique that has become one of the popular techniques for correcting cryptotia. However, satisfactory results are not always achieved by using this technique in cases with a shortage of the helix. We developed a new technique (double Z-plasty) in which a small Z-plasty in the helical rim is added to the usual large Z-plasty technique. An improved helical shape and enlargement of the ear can be achieved by using this technique. Almost all types of cryptotia can be treated by appropriately using the large Z-plasty and double Z-plasty techniques.
RESUMO
Damage and loss of ear cartilage can easily occur in a burned ear accompanied by severe extensive burns due to exposure of the cartilage or chondritis. Deformity can also occur due to later development of scar contracture despite minimal damage to the ear cartilage when the injury occurred. We have developed a new technique for treatment of a deep burn in the whole ear. METHODS: In the new technique, the ear is amputated, and soft tissues are denuded. The cartilage is banked in a subcutaneous pocket in the chest and later regrafted in combination with costal cartilage. RESULTS: Although techniques for regrafting banked ear cartilage have been reported, the reconstructed ear cannot acquire a good shape because of absorption of the cartilage or lack of intensity to sustain the outline of the ear. Meanwhile, when we tried to reconstruct an ear by only using costal cartilage, we found it difficult to fabricate a frame because most patients are adults in whom the costal cartilage is too rigid and fragile to be shaved or combined. In our technique, the frame has both the advantages of sufficient intensity in costal cartilage and a smooth curved surface together with elasticity in the ear cartilage. Ears reconstructed by our technique have a natural appearance. CONCLUSION: Our technique can be used for cases in which treatment for another large area of the body surface needs to be performed first to save the patient's life.
RESUMO
OBJECTIVES: To obtain new insights into research questions on how executive function and social interaction would be observed to change after the introduction of hearing aids (HAs) in older people with hearing impairment. DESIGN: Multi-institutional prospective single-arm observational study. SETTING AND PARTICIPANTS: Outpatients with complaints of hearing difficulty who visited HA clinics between October 18, 2017, and June 30, 2019, in 7 different university hospitals in Japan. METHODS: The inclusion criteria of the study named Hearing-Aid Introduction for Hearing-Impaired Seniors to Realize a Productive Aging Society-A Study Focusing on Executive Function and Social Activities Study (HA-ProA study) were age ≥60 years and no history of HA use. A series of multi-institution common evaluations including audiometric measurements, the digit symbol substitution test to assess executive functions, convoy model as an index of social relations, and hearing handicap inventory for the elderly (HHIE) were performed before (pre-HA) and after 6 months of the HA introduction (post-HA). RESULTS: Out of 127 enrollments, 94 participants completed a 6-month follow-up, with a mean age of 76.9 years. The digit symbol substitution test score improved significantly from 44.7 at baseline to 46.1 at 6 months (P = .0106). In the convoy model, the social network size indicated by the number of persons in each and whole circles were not significantly different between pre- and post-HA; however, the total count for kin was significantly increased (P = .0344). In the analyses of HHIE, the items regarding the family and relatives showed significant improvement. CONCLUSIONS AND IMPLICATIONS: HA use could benefit older individuals beginning to use HAs in executive function and social interaction, though the results should be interpreted cautiously given methodological limitations such as a single-arm short 6 months observation. Reduction in daily hearing impairment would have a favorable effect on relationships with the family.

BACKGROUND: Reconstruction of the upper eyelid with the same eyelid tissue is desirable because of the ability to achieve eye opening/closing and corneal protection, and a lid switch flap is a useful method. For total defects, almost all of the tissues of the lower eyelid should be used; however, the reconstruction of the lower eyelid donor site has often been undervalued. Reconstruction with an insufficient amount of soft tissue often results in complications such as lagophthalmos and ectropion. Here, we report our method of management of total upper eyelid defects and secondary reconstruction of the lower eyelid donor site. METHOD: A lid switch flap is designed on the lower eyelid as the first operation. As important points, the height of the flap of the anterior lamina should be the same but the conjunctiva as the posterior lamina should be harvested up to the conjunctival fornix to obtain sufficient tissue. After switching the flap, the lower eyelid donor site is reconstructed with sufficient tissue: cheek mucosa, conchal cartilage, and a reverse superficial temporal artery flap as a three-layered structure. RESULTS: Three patients were treated using our method, and we achieved favorable results with a sufficient amount of soft tissue for the reconstruction of the lower eyelid. CONCLUSION: Reconstruction of the upper eyelid with sufficient tissue from the lower eyelid is important for eyelid function.

We have already reported surgical procedures for lobule-type microtia that provide an excellent contour and shape of the ear with minimum sacrifice of the donor. We have succeeded in establishing a standard surgical technique for almost all types of concha-type microtia that effectively uses the remnant ear and can use a unified costal cartilage frame. METHODS AND RESULTS: The concept of our technique is that remnant cartilage should be used maximally but that the deformed area should be completely replaced by the costal cartilage frame. The differences between the cartilage frame for lobule-type microtia and that for concha-type microtia are that the lower half beneath the antihelical area and the concha cymba in the base frame are omitted in concha-type microtia. The area from the tragus to the incisura of the tragus in the antihelical-tragal frame is also omitted. The area of the helical crus in the helical frame and the lower half in the antihelix are not immobilized in the base frame and are free edges. On the other hand, the remnant cartilage outside the concha is removed, but the antitragus is preserved. When the cartilage frame and the remnant are incorporated, all of the components of the ear can be provided. CONCLUSION: The ears created by our technique have a natural appearance and clear contour.
RESUMO
Various techniques for correcting whistling deformities that occurred after primary surgery for cleft lip have been reported. These techniques are mainly intended to correct the lack of volume of the red lip. However, irregularity of the dry-wet lip junction (mucocutaneous junction) in the red lip has rarely been mentioned. If the wet lip is located in an exposed area, not only is the aesthetic appearance poor but also uncomfortable complications such as a crusted or bleeding lip repeatedly occur under a dry condition. A new technique for correcting the irregular line of the dry-wet lip junction is described in this report. The technique is simple. After removal of the exposed wet lip, flaps are designed on both dry lip sides of the defect as M-W-M plasty and are transposed toward the defect. The dog-ears are small; the scar is inconspicuous because it is incorporated with the wrinkle line, and scar contracture is prevented. In addition, more soft tissues may be included to correct a mild whistling deformity.

BACKGROUND: Various procedures for correction of congenital syndactyly of hand or foot have been described. For incomplete syndactyly, some of the reported techniques use only local flaps from surrounding tissues. A novel technique for the correction of incomplete syndactyly, using a dorsal triangular flap and two palmar small flaps, is described in this article. METHODS: A triangular flap is first marked on the affected web space. The size of the flap should be the same as the unaffected side or other web space. Then a straight line is marked from the proximal apex of the triangle to the level of the metacarpophalangeal (MP) joint. After full skin incision, minimal peripheral undermining is done, and the triangular flap is transposed proximally, as in the Y-V advancement procedure, and sutured. Then two incisions are made from the distal part of the flap, transposing small flaps as in the five-flap method, and closed primarily. RESULTS: We treated ten cases of congenital syndactyly of the hand or foot. We were able to correct a good web space without skin grafting in all cases. CONCLUSION: The design for our technique is simple, and the technique can be performed easily. The operation can be performed in a short time, the blood supply of the flap is preserved, the flap has a wide range of motion, and a deep and smooth dorsal slope is produced. This technique is an attractive alternative to previously reported methods for syndactyly correction.

BACKGROUND: It has been suggested that there is a close association of abnormality in auricular muscles with various congenital auricular deformities. However, there has been no investigation to determine what muscles are involved and how they affect the deformity. The authors examined abnormalities of auricular muscles for patients with various auricular deformities. METHODS: The authors examined 77 auricles of 62 patients with congenital auricular deformities, including cryptotia, Stahl's ear, prominent ear, lop ear, and others. The superior and posterior auricular muscles from the extrinsic auricular muscle group and the auricular oblique and transverse muscles from the auricular intrinsic muscle group were investigated. RESULTS: The authors found characteristic features of the abnormality of the muscle for each auricular deformity. In nearly all cases of cryptotia, abnormality was found in the superior auricular, auricular oblique, and auricular transverse muscles. Abnormal insertion was found mainly in the superior auricular muscle and was the main cause of cryptotia. In Stahl's ear, the major abnormality was abnormal insertion of the auricular transverse muscle, which creates an abnormal cartilaginous prominence in the scapha. The abnormality in cases of prominent ear was clearly limited mostly to the auricular transverse muscle and, in some cases, to the posterior auricular muscle. In lop ear, abnormality was mostly found in the auricular transverse muscle, with elongation, and in the superior auricular or auricular oblique muscle in some cases. CONCLUSIONS: There is a tendency for a specific muscle abnormality to be found in each deformity. It is important to identify the abnormal muscle and correct the abnormality during the operation.

BACKGROUND: Recently, auriculoplasty with costal cartilage grafting has been successfully used for correcting microtia and creating a clearly refined contour and a natural appearance of the ear. However, several important problems remain unsolved in these techniques. The authors describe an improved technique for harvesting costal cartilage with minimal morbidity and a new procedure for fabricating a cartilage frame that ensures a refined shape and rigid structure of the constructed ear. METHODS: Costal cartilage is harvested directly with a chisel. This technique enables some of the cartilage at the chest wall to remain intact. The base frame is fabricated by two cartilage blocks partly overlapped on the area of the antihelix. The thickness in the overlapping area emphasizes the contour between the antihelix and the helical crus. To prevent absorption of the cartilage, helical and antihelical parts are created using the outer rigid layer of the harvested cartilage and are covered as much as possible by perichondrium. RESULTS: A total of 137 ears in 121 patients were corrected with the authors' technique and followed up for at least 3 years. Almost all of the patients could walk within 2 days after the operation. The structure and contour of the constructed ear were well maintained. CONCLUSIONS: Attention should be given not only to successful outcomes of construction of the ear but also to minimal morbidity for the patients. Our technique made it possible to construct a cosmetically refined ear that could be maintained for a long period and minimize the pain and deformity of the donor's chest.

Z-plasty is one of the most widely employed techniques in plastic surgery and mainly serves the following purposes: elongation along the axis of the scar, dispersal of the scar followed by breaking up the straight-line scar and realigning the scar within the lines of minimal tension. It is useful especially to release linear-scar contracture, yet difficult for wide scars. This report describes a novel technique to release contracture effectively for any wide scars using a new design called double combined Z-plasty. The design is simple. The main limb is set to incise the wide scar, and this main limb is shared as a peripheral limb by two other Z-plasty designs. From the main limb, each central limb is designed along the margin of the scar in the opposite direction. The main and central limbs have 90° between them. Other peripheral limbs are then designed facing laterally to the intact skin to make 60° for the central limb. After skin incision, two triangular intact skin flaps could be inserted into the wide scar from both sides, making it possible to release contracture. We performed this technique on eight patients. All wounds healed well and scar contracture was satisfactorily released. This procedure is very useful for wide-scar contracture, compared to conventional Z-plasty.
