Facial symmetry has been proposed as a marker of developmental stability that may be important in human mate choice. Several studies have demonstrated positive relationships between facial symmetry and attractiveness. It was recently proposed that symmetry is not a primary cue to facial attractiveness, as symmetrical faces remain attractive even when presented as half faces (with no cues to symmetry). Facial sexual dimorphisms ('masculinity') have been suggested as a possible cue that may covary with symmetry in men following data on trait size/symmetry relationships in other species. Here, we use real and computer graphic male faces in order to demonstrate that (i) symmetric faces are more attractive, but not reliably more masculine than less symmetric faces and (ii) that symmetric faces possess characteristics that are attractive independent of symmetry, but that these characteristics remain at present undefined.

Objective To create a clinical consensus statement to address ambiguities and disparities in the diagnosis and management of nasal valve compromise (NVC). Methods An updated systematic review of the literature was conducted. In addition, a Modified Delphi Method was used to refine expert opinion and facilitate a consensus position. Results After two rounds of surveys and conference calls, thirty six items reached consensus, six items reached near consensus, and ten items reached no consensus. The categories that had the greatest percentage of consensus or near consensus items were: definition, history and physical examination, outcome measures, and management. Conversely, the categories with greater percentage of no consensus items were: adjunctive tests and coding. Conclusions The consensus panel agreed that NVC is a distinct clinical entity that is best evaluated with history and physical exam findings. Endoscopy and photography are useful but not routinely indicated, while radiographic studies are not useful in evaluating NVC. Other objective nasal outcome measures may not be useful or accepted for NVC. Nasal steroid medication is not useful for treating NVC in the absence of rhinitis, and mechanical treatments may be useful in selected patients. Surgical treatment is the primary mode of treatment of NVC, but bill coding remains ambiguous and confusing.

Chondrosarcoma is a malignancy rarely encountered in the head and neck. In an attempt to define this tumor's characteristics and response to therapy, all cases of chondrosarcoma treated at the University of Michigan over the past 25 years were retrospectively studied. Fourteen cases originating in the nose and paranasal sinuses, mandible, temporal bone, and larynx were reviewed. Aggressive surgical resection was the mainstay of treatment, and resulted in an overall survival of 70%, with an average follow-up of 3.5 years. Survival was highest in primary temporal bone lesions, and lowest in paranasal sinus lesions. Unresectable lesions were not cured by other modalities. This study, therefore, continued to support the crucial role of wide surgical resection in the treatment of head and neck chondrosarcoma, but conservative resection, when needed to preserve important structures, has resulted in long-term survival.

We characterized the breakpoints, gains, and losses of chromosome material in squamous cell carcinomas of the head and neck region from 29 patients. Cell lines were karyotyped in 1/3 of cases, direct preparations or early in vitro harvests in 1/3, and both in 1/3 of cases. GTG-banding was employed in all cases, as were C-banding and RBG- and AgNOR-staining in most. Some tumors were near-diploid and others near-tetraploid, but many had mixed populations, with diploid, tetraploid, and octoploid subclones representing essentially the same karyotypic pattern. The most frequent changes were deletions. Losses affecting 3p13-p24, 5q12-q23, 8p22-p23, 9p21-p24, and 18q22-q23 ranged in frequency from 40% to 60% of tumors. Loss of the short arm of the inactive X occurred in 70% of tumors from female patients, and loss or rearrangement of the Y occurred in 74% of tumors from male patients. Loss of 18q appeared to be associated with short survival, as did the presence of multiple deletions. There was gain (2-5 extra copies) of 3q21-qter, 5p, 7p, 8q, and 11q13-q23 in 28-38% of tumors. Three tumors had an hsr involving 11q13-q21. Gain of material at 11q13 is postulated to be associated with amplification of the PRADI/CCND gene at that locus. A translocation between proximal 1p and either an acrocentric short arm or proximal 8p or 9p was observed in squamous cell carcinomas of the head and neck region but not in female genital tract tumors. No other abnormalities appeared to be site specific, suggesting a pattern of genetic evolution in squamous cell carcinoma that is independent of anatomic site.

The purpose of this study was to assess the postoperative functioning of oral cancer patients with resections of the anterior tongue and floor of mouth, reconstructed with distal flap closure. Speech and swallowing performance was assessed for 11 men and 5 women preoperatively and at 1 and 3 months postoperatively following a standardized protocol. Speech tasks included an audio recording of a brief conversation and of a standard articulation test; swallowing function was examined using videofluoroscopy. Data were also collected on the number and duration of speech/swallowing treatment sessions, as well as the amount and duration of radiation therapy. Statistical analyses revealed that patients demonstrated a significant and severe impairment in speech and swallow functioning after surgery, with no recovery of function by 3 months post-healing. The degree of impairment in these patients may be related to the adynamic character of the distal flap used for reconstruction. Lack of improvement at the 3-month evaluation may be related to either the timing of postoperative radiation therapy or the low rate (44%) and amount of speech/swallowing treatment provided to these patients.

To evaluate aesthetic and functional results of reconstruction of the nasal alar subunit using free cartilage grafts with an interpolated cheek or forehead flap and a vascularized mucosal flap when required.Setting: University-based facial plastic surgery practice.Patients: A case series of 50 patients with primary alar defects undergoing nasal alar reconstruction.Main Outcome Measures: Observer's and patient's rating of the final results, patient's rating of breathing and level of self-consciousness, and medical record review of complications.Results: Most aesthetic outcomes were excellent to good. Breathing from the reconstructed side can be returned to preoperative status in most of these patients. Conclusion:Staged reconstruction of the nasal ala using free cartilage grafts, interpolated cheek or forehead and mucosal flaps when necessary, result in a highly aesthetic and functional outcome in most patients.
