Chin disfigurement following removal of alloplastic chin implants.

Insertion and subsequent removal of alloplastic chin implants is not an innocuous procedure, as commonly believed. Ten women, aged 23 to 62 years of age (mean 45 years) are reported in whom severe soft-tissue deformities were observed 6 months to 6 years (mean 32 months) after removal of their implants. Resulting deformities consisted of chin ptosis and bizarre soft-tissue pogonial bunching and dimpling in repose or on animation in 9 of the 10 patients (90 percent). Asymmetrical motion of the lower lip was noted by 5 of the 10 patients. Two patients complained of pain and tenderness over the soft-tissue pogonion. The "bizarre" soft-tissue chin deformities, once established, are virtually uncorrectable. Presently, we recommend serious consideration be given to performing an immediate osseous genioplasty in patients requiring removal of alloplastic chin implants to prevent the evolution of such abnormalities.

Research on predictability in cephalometry of the relationship of chin symphysis and nose-chin balance.

A sample of 120 untreated Caucasian adults was selected. All subjects were dental and skeletal Class I. The approach calls for the use of an original cephalometric method that is applied to the cutaneous profile by an esthetic curve extending from the nose to the chin. Statistical study of the sample confirms the existence of this cutaneous profile, regardless of facial type. This approach is proposed in combination with Sassouni's analysis to specify pogonion in the vertical and anteroposterior planes from which the vertical position of the chin (menton) may be deduced.

Occult chin abscess associated with an autologous chin implant.

The case of an occult abscess associated with an autologous nasal hump cartilage chin graft is presented. The graft was placed 30 years prior to secondary aesthetic surgery performed on December 22, 1992. In the course of the removal of the autologous tissue, an abscess pocket was discovered which subsequently cultured positive for Staphylococcus epidermidis. The area was thoroughly debrided and irrigated, and a preoperatively custom-fabricated silicone elastomer implant was placed. A 2-week course of appropriate antibiotic therapy was administered following receipt of the culture and sensitivity data. The patient suffered no postoperative complications. The bacteriology of implant colonization and infection in the light of host defenses would predict such a course, although, if known preoperatively, the more prudent course of abstinence from alloplastic implantation would likely be dictated in the aesthetic surgery patient.

Hereditary chin trembling or hereditary chin myoclonus?

Hereditary chin trembling is a rare autosomal dominant disease often considered as an "essential tremor variant". The clinical and neurophysiological data obtained in a new white family lead to the suggestion that this abnormal involuntary movement is a focal variant of hereditary essential myoclonus.
