Autoalloplast. An experimental and clinical study.

The concept of an autoalloplast offers the convenience of an alloplast and the safety and reliability of an autograft. An alloplast that acts as a scaffold for fibrous tissue ingrowth retains many of the characteristics of an autograft when reimplanted. Fibrous encapsulation is essential to the retention of all implanted impermeable synthetic materials. They then retain a potential for extrusion. Polyamide mesh, which allows the ingrowth of fibrous tissue, is a synthetic implant that circumvents the potential for extrusion. The fibrous tissue ingrowth provides substance to the graft, which permits precise carving with a scalpel after the initial implantation into a vascular area. A suitable period is necessary to allow fibrous tissue ingrowth. The incorporated mesh material is then harvested, shaped, and reimplanted into the augmentation site as an autoalloplast. A three-phase animal study to determine the feasibility of the autoalloplast concept is presented. It showed that fibrous incorporation of polyamide mesh occurs, and harvesting and reimplantation were feasible. It also demonstrated the superiority of the autoalloplast to withstand trauma without extrusion when compared with autogenous cartilage, polyamide mesh without fibrous assimilation, and Silastic. Since 1974, twenty-one humans have received successful implants with the autoalloplast. The patients have been followed up for two to 7 1/2 years, with all cases successful to date. The prospect of nurturing and biologically assimilating an implant in a safe and controlled area of a host and its subsequent reimplantation expands the field of reconstructive surgery and offers a practical method for managing certain facial deformities.

Management of the scoliotic nose.

The twisted nose represents an enigma to many rhinoplasty surgeons because of its frequent recurrence following correction. Reasons for failure include improper preoperative evaluation, failure to understand and compensate for the dynamics of cartilage and faulty surgical execution. One cannot expect a perfectly straight nose on all occasions but an analytic evaluation and appropriate surgical execution can routinely yield an apparently straight nose. The dynamics of the twisted nose are explored with special emphasis on the septal contribution to the scoliosis. The contribution of the bony and cartilaginous structures to the deformity is emphasized. An appreciation of the nasal cartilage-osseous unit is essential to understand the production of the twisted nose and its subsequent correction.

Management of the thyroid nodule.

Lobectomy-isthmectomy is part of our standard diagnostic approach for the solitary "cold" nodule of the thyroid. Although the majority of these prove to be benign, there is no noninvasive technique that can rule out malignant disease. It is necessary that the attendant morbidity for diagnostic surgery be extremely low. In our experience thyroid surgery for benign disease carries minimal risk. Resection of a lobe and isthmus with exploration and palpation of the opposite side constitutes our routine surgical management of the "cold" nodule. The nerve is always identified and preserved. In the past 18 months two minor complications have occurred postoperatively in 36 consecutive cases in which the lobe and isthmus were resected for benign disease.

Profile contouring including cheiloplasty.

Profile disharmony exists when there is an unattractive forehead-to-chin contour. An indication for correction arises when the appearance disturbs the patient. Often the patient believes rhinoplasty alone will improve the unpleasant profile. The surgeon must appreciate other deformitied and enlighten the patient of concurrent osseous and soft tissue abnormalities. Profile evaluation and treatment rarely requires complicated diagnostic and corrective measures. Complex mathematical evaluations followed by multistaged surgical procedures are impractical for most patients. My experience with augmentation of the nose and mentum with polyamide mesh in more than 200 cases indicates that it is a simple and safe material for implantation. Modification of the nasofrontal angle and cheiloplasty are minor adjunctive procedures and are readily combined with the basic rhinoplasty.

The grand biopsy for the "cold" thyroid nodule.

A lobe and isthmusectomy is our standard surgical management for the cold nodule of the thyroid. Experience indicates that the great majority of cold nodules prove benign. It is manifest that the attendant morbidity for this surgery be extremely low. Our experience reviewing thyroid surgery for only benign disease indicates that complications are indeed uncommon. Our surgical management of the cold nodule includes resection of a lobe and isthmus with exploration and palpation of the opposite side. The nerve is routinely identified and preserved. In the past 18 months, we have experienced two minor postoperative complications in 36 consecutive cases of the lobe and isthmus resection for benign disease.

A case against nasal packing.

Nasal packing is included in most technical descriptions of septal and rhinoplasty surgery with little accompanying discussion of its indications and possible pitfalls. We believe that routine nasal packing is not an innocuous step. There are certain specific indications for its use but these are uncommon. We suggest that exclusion of packing is a wiser alternative in routine procedures. Over 800 cases of nasal surgery have been reviewed with fewer than 9% requiring packing. The indications for such packing are described as are the alternatives. Problems and complications attendant with its routine use are explored.

The lateral conchal resection otoplasty.

A procedure for surgical correction of protruding ears has been utilized in 118 cases. The technique incorporates steps to correct the most common deformities found on preoperative evaluation. The lateral conchal resection com bined with mattress sutures is not complex and thus readily learned by residents. It has yielded consistently excellent cosmetic results combined with an exceedingly low complication rate. The procedure is adaptable to well over 90 percent of patients seeking an otoplasty procedure.

Use of implantation in facial deformities.

Augmentation of facial defects remains an area of challenge and controversy. Advocates of alloplastic implants cite the convenience of prepackaged materials, which they feel outweighs the possibility of rejection. Those favoring autografts prefer their long-term predictability, but must contend with resorption and the disadvantages of obtaining the implantation material. The use of supramid mesh may combine the advantages of allopasts with the long-term predictability of autografts after fibrous ingrowth has occurred. Our experience over the past 4 years in 164 cases indicates that supramide mesh may represent a significant advance in augmentation of facial deformities.

Allergy in Ménière's disease related fluctuating hearing loss preliminary findings in a double-blind crossover clinical study.

Several clinical reports suggest allergy as a causative or associated factor in the etiology of Ménière's Disease or endolymphatic hydrops. The A.A.O.O. subcommittee reported in 1972 its criteria for a therapeutic improvement in Ménière's Disease. This important report allows for clinical studies to proceed in a scientific manner using the subcommittee's criteria to evaluate the results. In an ongoing study utilizing a double-blind crossover technique, fourteen Ménière's patients have been evaluated for allergies utilizing the Rinkle and Lee techniques for inhalent and food allergies. Several cases directly relate symptoms to specific food ingestion and were given challenge food tests.

The nasal bony dorsum and cartilaginous vault. Pitfalls in management.

Our literature is replete with technical descriptions of rhinoplasty techniques designed to avoid certain complications. Analysis of 153 secondary rhinoplasties indicates that no procedure is immune to undesirable results and no specific technique can be employed to manage all potential problems. Critical scrutiny of these cases both preoperatively and intraoperatively indicated a decided recurrence of certain complications in the nasal bony dorsum and cartilaginous vault. Fifty-eight defects of the bony dorsum were encountered. These defects included open vault, wide dorsum, asymmetry, excessive or inadequate hump removal, abnormal nasofrontal angle, step deformities, and bony irregularities. Defects in the cartilaginous middle third of the nose occurred 91 times. These consisted to supratip prominence, valve collapse, asymmetry, and saddle deformity.
