Functional reconstruction for severe postburn microstomia.

A man with severe burn microstomia refractory to traditional management (Z release, skin grafting, splinting, bilateral commissuroplasty, and extensive physical therapy) is presented. Successful functional microstomia reconstruction was achieved with a three-stage approach consisting of the following: (1) lip, commissure, and cheek reconstruction with bilateral temporalis muscle transfers; (2) free flap neck and lower lip contracture release; and (3) vestibuloplasty with a stented full-thickness skin graft.

Facial skeletal growth after timed soft-tissue undermining.

This study was designed to answer the following questions: (1) Does aggressive bilateral soft-tissue undermining of the nasomaxillary complex in an immature animal without an iatrogenically produced cleft lip significantly inhibit growth? (2) If so, is the early timing of this undermining crucial? Fifty New Zealand White rabbits were used in this study, and bilateral buccal sulcus incisions with extensive nasomaxillary supraperiosteal undermining were performed in the experimental groups. There were five groups: (1) control, (2) undermining at 3 to 4 days, (3) undermining at 7 to 10 days, (4) undermining at 18 to 21 days, and (5) undermining at 50 to 56 days. The animals were sacrificed at 6 months of age, and direct osteometric measurements were made. Results demonstrated that a significantly retruded, constricted, and vertically shortened maxilla was produced as a direct result of bilateral nasomaxillary soft-tissue undermining alone regardless of the timing.

The Le Fort III advancement osteotomy in the child under 7 years of age.

This is a longitudinal study of 12 patients with craniofacial synostosis syndromes (Crouzon's, Apert's, Pfeiffer's) who underwent Le Fort III advancement under the age of 7 years (average age 5.1 years, range 4.0 to 6.7 years). The average follow-up was 5.0 years and included clinical, dental, and cephalometric examinations according to a prescribed protocol. The study demonstrated that the procedure could be safely performed in the younger child with an acceptable level of morbidity. There was a remarkable degree of postoperative stability of the maxillary segment. However, although vertical (inferior) growth or movement of the midfacial segment was demonstrated, there was minimal, if any, anterior or horizontal growth. Any occlusal disharmony developing during the period of follow-up could be attributed to anticipated mandibular development and could be corrected by orthognathic surgery. The roles of surgical overcorrection and anterior-pull headgear therapy after release of intermaxillary fixation are also discussed. The Le Fort III osteotomy is justifiably indicated during early childhood for psychological and physiologic reasons.

Hypertelorism correction in the young child.

This series reports on 20 patients who underwent orbital hypertelorism correction under 5.3 years of age (average age 3.9 years). The patients were followed an average of 5 years, and six patients were followed in excess of 7 years with clinical and cephalometric parameters. The study demonstrated that the procedure could be safely performed at this age and was aesthetically desirable. There was minimal clinical or cephalometric evidence of skeletal orbital relapse except in three patients, for whom individual explanations are given. During the period of postoperative study, nasomaxillary growth and development proceeded as expected, except in those patients with associated clefting. All patients demonstrated increased cranial width measurements preoperatively and postoperatively, but bigonial and bimastoid measurements were generally within normal range. Excessive resection of nasoglabellar skin at the time of hypertelorism correction appeared to adversely affect nasal development.

Local and distant recurrence rates in skin-sparing mastectomies compared with non-skin-sparing mastectomies.

BACKGROUND: Skin-sparing mastectomies (SSMs) are being used more frequently to treat many cases of breast cancer. This type of surgery maximizes breast skin preservation and facilitates immediate reconstruction, resulting in a superior cosmetic appearance after mastectomy and a more satisfied patient. Although SSMs are becoming more common, there are few data regarding the local and distant recurrence rates. METHODS: A total of 231 patients treated with mastectomies from 1990 to 1998 were studied, including 77 SSM and 154 non-skin-sparing (NSSM) mastectomy patients. RESULTS: The local recurrence rates for SSM and NSSM were 3.90% (3 of 77 patients) and 3.25% (5 of 154 patients), respectively. The local recurrence-free survival at 5 years was 95.3% for SSM patients and 95.2% for NSSM patients (P = .28). The distant recurrence rates of SSM and NSSM were 3.9% (3 of 77 patients) and 3.9% (6 of 154 patients), respectively. The distant recurrence-free actuarial survival at 5 years was 90.2% for SSM patients and 92% for NSSM patients (P = .07). CONCLUSIONS: Mastectomies using the skin-sparing technique do not appear to result in any increase in local or distant recurrence and improve aesthetic results of the immediate reconstruction.

Skin-sparing mastectomy with immediate breast reconstruction: a critical analysis of local recurrence.

PURPOSE: The purpose of this study was to provide follow-up data regarding the incidence of local breast cancer recurrence in patients undergoing skin-sparing mastectomy versus conventional non-skin-sparing mastectomy methods. PATIENTS AND METHODS: A retrospective follow-up study and analysis were performed of patients who underwent mastectomies for invasive breast cancer at The New York Presbyterian Hospital, Cornell University Medical College and Strang-Cornell Breast Center between 1990 and 1998. RESULTS: A total of 198 patients were identified in this study, and the mean follow-up was 49 months. This group included 71 patients who underwent skin-sparing mastectomy and 127 who underwent non-skin-sparing mastectomy procedures. No statistical differences in local recurrence rates were demonstrated between patients treated with skin-sparing mastectomy and those who underwent non-skin-sparing mastectomy. Local recurrence was present in four of 71 (5.6%) patients undergoing skin-sparing mastectomy and in five of 127 (3.9%) of those undergoing non-skin-sparing mastectomy. CONCLUSIONS: The use of skin-sparing mastectomy does not lead to an increase in local recurrence rates when compared with conventional non-sparing mastectomies and provides for improved aesthetic results after immediate reconstruction.
