摘要:

There is a network of fascia in the upper eyelid that serves to transmit and distribute the motor power of the levator palpebrae muscle to the superficial tissues. The architecture of this network was studied intraoperatively. The results demonstrate that there is a superficial fascia under the orbicularis muscle which fuses with the levator aponeurosis at the level of the lid fold. Below the fold, these fascia remain fused or “conjoined.” Thus, the fold in the upper eyelid reflects the union of fascia occurring internally and does not result simply from the levator aponeurosis inserting into the skin.This article describes the anatomy and surgical identification of the upper eyelid fascia. I contend that the fascia constitutes an important internal framework for the upper eyelid, shaping the lid fold while elevating the tarsal plate in perfect synchrony. For the surgeon, visualizing the fascial architecture is a great aid in the correction of a variety of difficult eyelid deformities.

摘要:

In treatment of moderate to severe blepharoptosis in the Oriental, an excellent result can be obtained by frontalis suspension using free palmaris longus tendons. Postoperative functional training is unnecessary. Children of 5 or 6 with congenital upper eyelid ptosis are favorable candidates for correction by this method. In traumatic cases, the operation may be performed about six months after injury.

摘要:

There is a high incidence of complications following treatment of fractures of the dentulous mandible at our institution, which has led us to scrutinize the criteria for maintaining teeth in the line of fracture and to evaluate other factors that may compromise healing of the fractured mandible, especially in an unreliable patient population. We have reviewed the opinions of various authors and agree that management decisions must be individualized. We recommend prompt and stable immobilization, adequate observation, use of a “tickle file” to keep track of missed appointments, and long-acting intramuscular prophylactic antibiotic coverage, all of which will help minimize morbidity associated with teeth in the line of mandibular fractures, especially in high-risk patients. We also recommend extraction of fully or partially erupted third molars in the line of fracture as well as deeply carious teeth, severely mobile teeth, or teeth with half or more of their root surface exposed to the fracture line. Finally, we recommend that intraoral rather than extraoral open reduction be considered when teeth are to be extracted in order to avoid contamination with the extraoral environment, to enhance surgical access, and to lower postsurgical morbidity.

摘要:

A specific 6-keto-ptostaglandin F1αradioimmunoassay was used to follow tissue prostacyclin formation in a series of bipedicle delayed flaps in 2 pigs. Flap tissue samples were taken at intervals for 21 days. Prostacyclin formation started to rise at day 4 and reached a peak at day 7. The increase was statistically significant (p<0.05) compared with other days and with the control. This result implies that the increased hemodynamics that occur following the “delay” procedure are effected by prostacyclin, which is a potent humoral factor for vasodilation. The peak of prostacyclin formation one week following surgery correlates well with previous reports demonstrating a maximal blood flow one week after the “delay” procedure.

摘要:

The Japanese are mesocephalic and their faces tend to look broad when viewed from the front. The main reason for this appearance is the prominent zygoma. The temporal area is closely related to the zygoma, and when this portion of the face is excessively concave, the zygoma stands out and causes the face to appear seedy or older than the actual age. To cure this condition, there have been three conventional operations performed in Japan, which are not without shortcomings. The authors have improved on these methods and have succeeded in solving most of the problems in 21 cases by devising a method in which a soft silicone plate is inserted under the temporal muscle fascia.

摘要:

The use of the carbon dioxide laser for minor hand problems is reviewed, and the physiological effects of laser treatment are discussed. Forty-one patients have been treated during a one-year period for warts, nail disorders, and a variety of benign neoplasms. Results of CO2laser treatment are equivalent to those of other methods with less pain and disability. Future applications of the CO2laser are discussed.

摘要:

An extension of the “crane” principle is presented for use in compound frontal defects, and several case histories are described. The procedure would obviously not be possible if a foreign material had been used for the osseous defects, since take of the skin graft depends on circulation, through the autogenous bone graft.

摘要:

We review various incisions for treatment of tumors of the face and parotid and submaxillary regions, as well as for radical neck surgery. A contribution to this field is made in the form of facial and cervical incisions that not only provide broad exposure of the region affected by the tumor, but also involve incision traces based on plastic surgery criteria. In this respect, we describe plastic modeling of the facial, submaxillary, and neck contours, resorting to the sternocleidomastoid and trapezius muscles.

摘要:

Parotid gland tumors in infancy and childhood are rarely seen and infrequently documented. Among them, hemangioendothelioma and mixed tumors are the most common. Parotid lymphangioma is very rare. This report presents a case of parotid lymphangioma and discusses the clinical, gross, and histological features, differential diagnosis, and treatment.
