Nerve staining with leucomethylene blue: an experimental study.

Identification and preservation of the facial nerve during extirpative and reconstructive surgery represents a challenge even for the experienced surgeon. We present an experimental intraoperative technique for staining the facial nerve and its branches that is safe, accurate, and inexpensive. Leucomethylene blue is injected into the precise region of the facial nerve. Staining of the surrounding tissues is efficiently reduced by irrigation with ascorbic acid solution, leaving only the facial nerve stained. This technique has been encouraging in rabbits, and with additional experience, we anticipate its use for intraoperative staining of the facial nerve in humans.

Early treatment of rhinophyma--a neglected entity?

Patients are aware when even minimal bulbosity appears secondary to acne rosacea. Many suffer psychic trauma as a result. Early surgical treatment of this entity eliminates disfiguring hypertrophy. We advocate early surgical treatment of even minimal rhinophyma.

Reconstruction of facial deformities with alloplastic material.

The two most ideal and versatile foreign materials for reconstruction of facial bone deformities are silicone rubber and methyl methacrylate. Their biomechanical characteristics are uniquely suited to facial implantation for reconstruction of complex, irregular bony defects. The advantages and disadvantages of each are discussed, along with specific indications for their use. Surgical approaches and various methods of fabrication and fixation are presented and illustrated. The hazards and potential disappointments in the use of these and other alloplastic implants are reviewed.

Congenital arteriovenous malformation of the face and scalp.

A case of congenital arteriovenous fistula of the forehead and scalp is presented. A review of the embryology, incidence, clinical findings, and diagnostic techniques is discussed along with the various modes of therapy. The ideal treatment of congenital arteriovenous malformation is early, total removal of the tissue involved.

Procedures and equipment for staining large numbers of plant root samples for endomycorrhizal assay.

A simplified method of clearing and staining large numbers of plant roots for vesicular-arbuscular (VA) mycorrhizal assay is presented. Equipment needed for handling multiple samples is described, and two formulations for the different chemical solutions are presented. Because one formulation contains phenol, its use should be limited to basic studies for which adequate laboratory exhaust hoods are available and great clarity of fungal structures is required. The second staining formulation, utilizing lactic acid instead of phenol, is less toxic, requires less elaborate laboratory facilities, and has proven to be completely satisfactory for VA assays.

Medial thigh lift.

Medial thigh ptosis, characterized by rhytidosis and seen commonly from aging and great weight loss, is seldom improved by lateral or posterior thigh lift. A simple procedure has been developed to correct this laxity of the upper, inner thighs. This consists of symmetrical resection of a crescent-shaped segment of skin and subcutaneous tissue having the distribution of an L1 embryological dermatome, just inferior to the inguinal crease. Despite temporary sensory loss and spreading of scars in some patients, the procedure has been gratifying to both patient and surgeon. Patients must be carefully selected, as the procedure does not correct either trochanteric lipodystrophy or ptosis, or lipodystrophy medial to and just superior to the knee.

Restoration of frontal contour with methyl methacrylate.

Of the various materials currently available for reconstruction of bony frontal deformities, bone cement (methyl methacrylate) has been judged to be superior in its simplicity, reliability, and aesthetic potential. It is uniquely suited to reconstruction of irregular defects of the forehead. Its biological characteristics, advantages, and hazards are presented along with the techniques of its use. Clinical examples illustrate the results obtained with minimal preparation, surgical time, and morbidity.

Body sculpturing.

Significant improvements in body contour can be accomplished by surgical procedures having reliable, predictable results. Similar to the modern sculptor of inanimate art forms, plastic surgeons have utilized new materials and devised new techniques to achieve aesthetic improvement of the face, trunk, and extremities. The goals of the surgical sculptor are perhaps more challenging than those of the pure artistic sculptor, not only because they must result in improved appearance but also because the surgeon is limited at all times by considerations of regional anatomy, the availability of viable tissue materials, and the safety of his patient.

Midfacial fractures from vehicular accidents.

An effort is made to simplify, categorize, and outline the various forms and treatment of midfacial trauma from automotive crashes. Panfacial fractures resulting from high speed automotive accidents will continue to be a challenge to the innovative and persistent surgeon seeking the best possible results.

Frontal sinus and supraorbital fractures from vehicle accidents.

Fractures of the upper third of the face from vehicle accidents are relatively uncommon but can have serious associated injuries of the dura and frontal lobe when they do occur. The injury may result from the victim's face either striking the dashboard or bouncing violently off the lower broken edge of the penetrated windshield.
