The effects of smoking on experimental skin flaps in hamsters.

To study the effects of the inhalation of cigarette smoke on the survival of skin flaps, 30 Syrian Golden hamsters were divided into three groups of 10. Two of these groups were acclimatized to cigarette smoke in increasing increments for 9 weeks in standard Hamburg I smoking cages. The third group of 10 (group A) served as controls and were sham-smoked throughout the experiment. After acclimatization, one group of 10 (group B) was smoked for a further 6 weeks. A standard axial-pattern flap was then raised on the dorsum of the animals. Ten animals in group C were smoked for 6 weeks preoperatively and for 2 weeks postoperatively, at which time the animals in all groups were sacrificed. All animals survived the experiment. The flaps in control group A all survived without necrosis. Two of the 10 dorsal flaps sustained terminal necrosis in group B animals. Six of the 10 flaps resulted in significant terminal necrosis in group C animals. Statistical analysis of the results indicated a significant comparison between control group A and group C of those animals smoked throughout the experiment. We conclude from this experiment that the inhalation of cigarette smoke consistent with that of a heavy smoker (2 packs per day) has an adverse effect on wound healing of skin flaps in hamsters. Apparently, cessation of smoking even at the time of surgical preparation of the flap obviates much of the noxious effect and increase flap survival significantly.

Orbital abscess following blepharoplasty.

Orbital abscess following blepharoplasty is surprisingly rare. The diagnosis may not be obvious from the physical signs alone. Ultrasonography is a helpful diagnostic tool in such problems. The abscess cavity can be visualized. A case of orbital abscess is presented.

The effect of cigarette smoking on skin-flap survival in the face lift patient.

Our data demonstrate that a significant number of skin sloughs observed after face lift surgery are due to patients' cigarette smoking. Because an appreciable part of every surgeon's practice consists of smokers, the implications of this study, in terms of patient selection and preoperative counseling, seem considerable.

An investigation of bacteremia during rhinoplasty.

The rarity of infection after rhinoplasty is not well understood. Despite the apparent low incidence of this complication, many surgeons administered perioperative antibiotics to prevent infection. We studied whether a bacteremia composed of nasal flora can originate during rhinoplasty. Fifty-two health patients admitted for rhinoplasty were studied. Blood and nasal cultures were drawn immediately before operation and blood cultures 5 and 15 minutes after completion of the nasal osteotomies. With the exception of one instance of likely contamination, none of the blood cultures grew microorganisms. Neither local nor systemic infections occurred in any patient. The negative results of this study suggest an exceedingly low incidence of bacteremia during rhinoplasty. For this reason, the value of perioperative antibiotic prophylaxis is questionable.

Tongue-flap reconstruction of the lip vermilion in hemifacial atrophy.

The lips are key features to be considered in facial balance. Correction of lip atrophy in Romberg's disease, therefore, contributes significantly to restoration of facial symmetry. Along with other ancillary surgical procedures used for facial reconstruction in hemifacial atrophy, tongue flaps provide an excellent means of correction of the lip deformity with minimal morbidity and good results.

Lower blepharoplasty with emphasis on the orbicularis muscle.

The skin-muscle flap technique in blepharoplasty has, in our opinion, distinct advantages over the classic skin flap operation. Morbidity is diminished by avoiding dead space and preserving the integrity of the skin-muscle intimate attachments. Excessive muscle, an entity of which we are becoming more aware, can be handled simultaneously by cautious excision. Finally, secondary operations to correct recurrent skin excess can be performed in virgin territory at the level of the skin-muscle interface. Even though this technique is applicable to the vast majority of patients, certain deformities in which a marked excess of skin is the chief anatomic problem are best corrected with a classic skin flap procedure.

Surgical safaris with the East Africa Flying Doctor Service.

A few hundred small mission and government hospitals serve the 20 million people who live in rural East Africa. The physician-patient ratio is 1:25,000. Surgical support to many of these hospitals is provided through the East Africa Flying Doctor Service of the African Medical and Research Foundation. Small aircraft that are coordinated by a wide radio network bring surgical capability to a maximum number of patients in this area of 1,300,000 sq km (500,00 sq miles). The clinical problems, differential diagnoses, operative decisions, risk, and complications of surgical care all have a distinctly African quality. The working conditions and variety and magnitude of problems provide a stimulating challenge. Surgical safaris are a catalyst for gaining acceptance of modern scientific methods by Africa's tradition-oriented tribesmen.

Ocular manifestations and treatment of hemifacial atrophy.

Enophthalmos, flattening of the maxilla that may progress to inferior orbital rim and floor defects, eyelid atrophy, and slight relative hypotony occurred in patients with hemifacial atrophy. Less common manifestations included pupillary and iris abnormalities, vertical muscle imbalances, and retinal changes. The prognosis for vision was good. Fluid silicone injection was the major modality in treatment and the results were generally excellent.

Rhinoplasty in the older adult.

In attempting to determine the suitability of an older person for cosmetic rhinoplasty, the surgeon must keep in mind not only anatomical considerations, but also, even more important, the emotional and psychological expectations of each patient. The surgeon should make every attempt preoperatively to arrive at a meeting of the minds with the patient, so that he has a thorough understanding of that patient's desires, needs, and hopes. If the surgeon believes he is able to achieve or even come close to his patient's goals by a conservative operative approach, there is no reason why a rhinoplasty should not be undertaken. However, it is the author's experience that rhinoplasty in the older patient often fails to produce a result wholly satisfactory to the patient and the physician, and it is necessary to keep this in mind when selecting patients.

Complications of rhytidectomy.

A review of the more common and/or more serious complications which may follow rhytidectomy has been presented. The surgeon who performs face lift surgery must be aware of these complications, their incidence, their management, and, in many instances, how they can be prevented, as prevention is the best treatment for postrhytidectomy problems.

The male rhytidectomy.

More men are undergoing rhytidectomy now. This operation is specifically different in the preoperative planning, the surgical procedure, the postoperative complications, and the final results (compared to rhytidectomy in females). Large hematomas occurred in our male patients more than twice as often as in females.
