OBJECTIVE: We sought to evaluate surgical wound infection rates in patients undergoing skull base surgery without hair removal. METHODS: We undertook a retrospective study of 175 skull base operations performed without hair removal. Anterior operations were conducted via the subcranial approach (n = 120) and lateral or posterior procedures via various approaches (n = 55). Wounds were examined daily during hospitalization and at routine outpatient follow-up (8 to 45 months) and classified according to the Center for Disease Control and Prevention guidelines. RESULTS: The overall surgical wound infection rate was 1.1% (2 of 175): 0.8% (1 of 120) for anterior and 1.8% (1 of 55) for lateral or posterior procedures. It was similar for clean operations (lateral and posterior) and clean-contaminated (anterior) procedures and was less than or similar to the rates reported for skull base procedures with hair removal. No wound infection occurred among the infected (trauma, fungal infections, and brain abscess) patients. CONCLUSIONS: Skull base surgery without hair removal is safe and not associated with increased risk of wound infection. The method may prevent additional psychologic stress, promote restoration of the patient's self-image, and accelerate his or her return to normal life.

Corrective hair restoration techniques for the aesthetic problems of temperoparietal flaps.

BACKGROUND: Temperoparieto-occipital flaps (Juri flap) and temperoparietal flaps (Elliott) were commonly performed in the previous decades but have fallen out of favor for the most part with the development of follicular unit hair transplantation. Besides high complication rates, these procedures created straight abrupt hairlines in many cases, posterior hair direction, hair density that was disproportionately thick, and blunt temperofrontal angles. OBJECTIVE: Because there are many patients who live with cosmetic deformities created by previous flap procedures, the objective of this article is to present a series of techniques that will restore these patients to normal cosmesis. METHODS: The techniques for amelioration of poor cosmesis secondary to flap procedures are (1) undulating follicular unit grafting anterior to the hairline, (2) removal of 2- to 3-mm cylinders of hair-bearing scalp at the anterior hairline, (3) removal of 2- to 3-mm cylinders of hair-bearing scalp from within the flap itself, and (4) appropriate fusiform excision techniques to create a normal temperofrontal angle. RESULTS: The combination of the aforementioned techniques has restored a very natural cosmesis in patients who have poor aesthetics after flap surgery. CONCLUSION: Many patients exist who have had Juri and Elliott flaps. Although the cosmetic deformities that are created from these flaps are difficult to improve, they can be ameliorated effectively through a series of maneuvers that are described in this article.

OBJECTIVE: To evaluate maternal and fetal hair mercury levels in relation to the placement of dental amalgam tooth restorations. DESIGN: Cross sectional study involving women who never had dental amalgam restorations placed, women who had amalgam restorations placed before pregnancy and women who had restorations placed during the index pregnancy. SETTING: North of England Maternity Hospital. SAMPLE: Fifty-three healthy women who delivered healthy babies at term. METHODS: Maternal and fetal hair was collected in a standardised manner in the first few days following delivery. MAIN OUTCOME MEASURES: Maternal and neonatal hair mercury concentrations. RESULTS: When compared with women without restorations, there was a significant increase in the maternal hair mercury concentration in women who had dental amalgam placed outside of the index pregnancy and also in women who had dental amalgam placed during the index pregnancy. The fetal hair mercury concentration was significantly higher in babies when mothers had been exposed to dental amalgam either before pregnancy or during pregnancy compared with unexposed babies. There was no difference in the maternal or fetal hair mercury levels in the groups of patients who had dental amalgam placed before or during pregnancy. CONCLUSIONS: Maternal and fetal hair mercury levels were significantly higher in women who previously had dental amalgam restorations placed. There was no evidence that placement of dental amalgam restorations in pregnant women who had already similar restorations increased the maternal or fetal hair mercury level.
