Max Brödel's contributions to otolaryngology-head and neck surgery.

Max Brödel arrived in the United States in 1894 to work as a medical illustrator at the Johns Hopkins Hospital. He brought with him an extensive background in medical sciences and illustration. This allowed him to develop an advanced style and technique that would greatly influence the profession of medical illustration. Much of Brödel's work concerned the head and neck region and is of particular interest to otolaryngologists. This article reviews the historical aspects of Brödel's career and highlights his contributions to Otolaryngology-Head and Neck Surgery.

Transsphenoidal approach to the sella: the Johns Hopkins experience.

The transsphenoidal hypophysectomy has become a relatively frequent procedure in recent years, with the otolaryngologist playing a major role in its renewed popularity. This paper reviews the evolution of pituitary surgery, discusses the surgical technique currently used, and reviews the results and complications of 114 cases over a 13-year period. Of the 129 procedures performed at Johns Hopkins Hospital between 1970 and 1983, 114 charts were available for review. Twelve of these were palliative hypophysectomies and 102 were for sella tumors. Sixty-eight patients were treated with surgery alone, and 34 received surgery and postoperative irradiation. Significant complications such as CSF rhinorrhea, diabetes insipidus, meningitis, septal perforation, anosmia, and visual field defects are discussed. The mortality rate for the series was 1.7%. These results are compared with those of previously published series and the differences are discussed in detail. In analyzing these data we feel that the transseptal, transsphenoidal hypophysectomy has become a safe and effective therapy for sella lesions.

Modification of the subunit principle for reconstruction of nasal tip and dorsum defects.

This article reports our observations on, and modification of, the subunit principle with regard to reconstruction of nasal tip and dorsum defects. Forty-two patients who underwent reconstruction of a nasal tip and/or dorsum defect with a forehead flap were reviewed. These patients were categorized by how the subunit principle was used in their reconstruction and graded on the aesthetic outcome of the reconstruction. We found that the patients who had both the nasal tip and dorsum replaced obtained better results than those who had just 1 subunit replaced (P = .008). Review of postoperative photographs shows that the reason for this discrepancy in aesthetic outcomes is the line of transition between the forehead skin and remaining nasal skin if only 1 subunit is replaced. With this observation in mind, we feel that patients undergoing reconstruction of the nasal tip and/or dorsum should be evaluated for discrepancies in tissue type between the recipient nasal site and forehead donor site. If the tissues are noted to be significantly disparate, the reconstructive surgeon may consider replacing both subunits with a single forehead flap.

Botulinum toxin A for mentalis muscle dysfunction.

OBJECTIVE: To describe the use of botulinum toxin A for treatment of mentalis muscle dysfunction secondary to failed augmentation mentoplasty. DESIGN: Clinical observations were made in the treatment of mentalis muscle dysfunction. Patients with the postmentoplasty signs of mental skin dimpling and soft tissue ptosis were injected with 20 U of botulinum toxin A and observed for visual and functional improvement. Photographs were taken for documentation. SETTING: Private facial plastic surgery practice. PATIENTS: Three patients with a history of failed augmentation mentoplasty were identified and signs/symptoms recorded. Each patient was treated with 20 U of botulinum toxin A and observed for clinical improvement. MAIN OUTCOME MEASURES: Pretreatment and posttreatment photographs of active and passive mentalis function together with patient satisfaction surveys. RESULTS: Of the 3 patients treated, all reported alleviation of the mentalis dysfunction and improved appearance. The symptoms began to return as the botulinum toxin A effects subsided. CONCLUSIONS: Botulinum toxin A is a safe and effective treatment of mentalis dysfunction secondary to failed augmentation mentoplasty. The effects are predictable, although temporary.
