Current thinking in lower third molar surgery.

The removal of lower third molar teeth is one of the most common surgical procedures performed worldwide, but many concepts in this surgery have been unclear and have engendered different opinions. This paper aims to review current thinking in certain pertinent aspects of this surgery to update the reader on the most current research and synthesise it to make clinical recommendations. Topics covered include preoperative imaging, timing of removal, flap design, lingual retraction, coronectomy, lingual split, closure techniques, and use of antibiotics, steroids, and drains.

Women who wish breast reconstruction: characteristics, fears, and hopes.

The aims of the present study were to identify the characteristics of a consecutive series of women with newly diagnosed breast cancer and to evaluate the perceived benefits and disadvantages of breast reconstruction. A consecutive series of 125 women completed the Breast Reconstruction Questionnaire, the Hospital Anxiety and Depression Scale, and the Eysenck Personality Questionnaire. The median age was 48 years (range, 28 to 75 years). A total of 49.6 percent (n = 62) indicated that, if it were possible, they would like breast reconstruction. Logistic regression (simultaneous entry) revealed that younger women (p = 0.0001) and more depressed women (p = 0.026) were more likely to wish reconstruction. Marital status, tumor size, extroversion, neuroticism, and tough-mindedness did not independently predict the desire for reconstruction. If given a choice of reconstruction at 3 months or 6 months after mastectomy, of the women who wished reconstruction, 74 percent would prefer it at 3 months. Of the women who wished reconstruction and expressed a preference, 63 percent were afraid reconstruction might mask recurrence, 39 percent were afraid that reconstruction might cause the cancer to return, and 89 percent thought they would be concerned with their appearance after the operation. Positively, 94 percent considered that reconstruction would be beneficial in terms of their self-esteem, 86 percent indicated that reconstruction would give greater freedom to wear any clothing, and 86 percent thought that the cosmetic appearance of breast reconstruction was better than that of a prosthesis. Concerns about recurrence were common. A better understanding of the concerns of women with regard to reconstruction would allow more informed preoperative discussion.

When can patients blow their nose and fly after treatment for fractures of zygomatic complex: the need for a consensus.

PURPOSE: To determine current professional advice to patients about refraining from nose blowing and air travel following treatment of zygomatic fractures. METHODS: A postal questionnaire was sent to 261 consultant oral and maxillofacial surgeons (OMFS) in the UK. They were asked about advice given to patients regarding length of time to refrain from nose blowing and air travel following treatment of zygomatic fractures. RESULTS: A total of 184 (71%) replies were received. Advice regarding the length of time to refrain from nose blowing and air travel ranged from no advice to 8 weeks. About 90% of respondents based their advice on common sense and traditional practice. CONCLUSIONS: Advice given to the patients following the treatment of zygomatic fractures varies widely. Most consultants based their advice on traditional practice and common sense. In the absence of widely accepted guidelines, there is a need for an agreement among clinicians on advice given to the patients.

Determination of the lysozyme deposit curve in soft contact lenses.

PURPOSE: To determine lysozyme deposition as a function of time in soft, high-water content, ionic (group IV) contact lenses. METHODS: ACUVUE lenses were worn on an extended-wear basis (15 minutes, 2 hours, 4 hours, 6 hours, 8 hours, 1 day, 2 day, and so forth, up to 11 consecutive days). New lenses were dispensed at the beginning of each lens-wear period. After each wear cycle, lenses were analyzed for lysozyme deposition by high performance liquid chromatography. RESULTS: Lysozyme rapidly accumulated on lenses (15 minutes approximately 55 microg/lens) and reached a plateau level by day 6 ( approximately 1300 microg/lens). Most patients in the study showed a plateau range between 1200 and 1400 microg/lens. Six-month and 12-month follow-up studies with ACUVUE lenses showed minimal variation at the 5-day wear time point between the initial, sixth, and 12th month results. CONCLUSIONS: This study measured the rate of lysozyme buildup on lenses over time and demonstrated that lysozyme levels associated with group IV lenses reached a plateau after approximately 1 week of extended wear. Little variability was seen in lens lysozyme deposition up to 1 year later. The information derived from this study concerning the rate and variability of deposition has implications for the design and interpretation of cleaning studies and contact lens performance evaluations.
