摘要:

On the basis of over 100 fresh cadaver dissections as well as a review of nasal embryology and development, several important observations can be made regarding surgical anatomy of the nose. Within the bony vault, nasal profile modification consists of two distinct maneuvers: bony hump removal and modification of the nasofrontal groove area. The cartilaginous vault is in reality a unified, winged structure composed of septum and upper lateral cartilages. Within the nasal lobule, a continuous cartilaginous ring exists. The nose itself is covered by a superficial muscular aponenotic system.

摘要:

Large foot defects unsuitable for reconstruction by local foot flaps are most expediently salvaged with distant free-tissue transfers. Although muscle flaps are preferred for infected wounds, coverage of the clean or acute foot deformity may be better achieved with the innervated radial forearm fasciocutaneous flap. This almost ideal donor site has been used by us for all traumatic foot defects requiring free flaps during the previous year. Our results document that in the 5 available clinical examples, restoration of normal foot contour, durability during ambulation, and an excellent aesthetic appearance were achieved.

摘要:

A technique to repair clefts of the primary palate is described. This technique is a combination of several surgical methods previously reported to which some modifications have been added. The advantages of this technique are compared with those associated with other surgical methods. A more natural result is obtained with this technique: The undesirable vestibular fistula is avoided and a deeper buccal sulcus is achieved. The criteria in the management of the nose and orbicular muscle is analyzed.

摘要:

Occasionally radiation is required as adjunctive therapy following mastectomy for breast cancer. The effects of radiation on a developing implant capsule are unknown, but they are very important in relation to the increased use of immediate reconstruction. Experiments were performed on rabbits to study the effects of postoperative radiation therapy on capsule contraction and thickness. The results of these experiments suggest that radiation has no effect on implant capsules.

摘要:

Identification of the endogenous microbiological flora of the human breast and its role in breast infections following subglandular augmentation or reduction mammaplasty was undertaken. A total of 231 cultures were performed on 59 breasts in 30 patients. Patients were followed for 12 months.No fungus was cultured from any specimen. Of the breasts cultured 53% were positive for coagulase-negative staphylococcus. Other aerobes found included diphtheroids, lactobacillus, D-enterococcus, micrococcus, and α-hemolytic streptococcus. Propionibacterium acne was the most frequent anaerobic bacteria cultured. Other anaerobes included peptococcus and clostridium sporogenes. There was no correlation with respect to the type of bacterium and the depth within the breast where the culture specimens were taken. Postoperative wound infections developed in 2 of 19 patients undergoing reduction mammaplasty. Bacteria identical to those cultured at the time of surgery were again cultured from the wound. Twenty subglandular augmentation mammaplasties were performed with a 25% capsular rate at one year. Two capsules were associated with no bacterial growth at the time of mammaplasty surgery, whereas three were associated with coagulase-negative staphylococcus, Propionibacterium acne, and diphtheroids, respectively. Of the 15 breasts with no capsular contracture after one year, operative culture revealed coagulase-negative staphylococcus in 8 and no bacterial growth in 7.Even breast tissue located deep within the gland away from the nipple contains a flora that is similar to that of normal skin. Cases of infection in which the endogenous bacteria were correlated with later infection was documented.

摘要:

An implantable and disposable tissue oxygen tension (Po2) probe, useful as a clinical monitor following free-tissue transfer, is described. Experimentally, using the rabbit epigastric groin flap model, we have found it to be a sensitive indicator of arterial and venous occlusion. Oxygen can be given to verify the integrity of the monitoring technique and check any abnormal reading. Animals administered oxygen will have a rapid increase in tissue Po2when the pedicle is intact. If compromised by arterial or venous occlusion, the low readings demonstrate no change. The application of this new technique for monitoring free flaps in 12 patients is presented. In 2 patients the tissue Po2monitor successfully detected early vessel thrombosis, resulting in reexploration of the anastomoses and salvage of the free flaps.

摘要:

Squamous cell carcinomas of the nasal floor present problems for surgical therapy. Similarly, basal cell carcinoma of the nasal floor and alae requires extensive reconstruction when cures are obtained. To improve the results, we have treated the squamous cell carcinomas with topical 5-fluorouracil to obtain sensitization and shrinkage of the tumor before resection. The same has been done with basal cell carcinomas, but in selected patients the topical 5-fluorouracil has been continued until biopsies are negative. Thus, the costs of resection and reconstruction have been avoided and excellent cosmetic results are possible. This treatment is lengthy and requires weekly supervision. It offers a different approach that gives surgeons further options in treating these difficult carcinomas in carefully selected and cooperative patients.
