    Chondroid syringoma of the upper lip: a case report.
    (2004) Arikan O.K.; Erdogan S.; Muluk N.B.; Koç C.
    Chondroid syringoma (mixed tumor of the skin) is a rare benign neoplasm of the sweat glands which often occurs in the head and neck region. We present a 73-year-old white farmer man with a mass in the anterior surface of the upper lip that was histologically diagnosed as a chondroid syringoma after surgical wide excision. There were no signs of recurrence during a follow-up of 14 months.

    Is there a relationship between mastoid pneumatisation and facial canal dimensions?

    Objective To evaluate mastoid pneumatisation and facial canal dimensions.Method In this retrospective study, 169 multidetector computed tomography scans of temporal bone were reviewed. Facial canal dimensions were evaluated at the labyrinthine, tympanic and mastoid segments using axial and coronal multidetector computed tomography scans of temporal bone. Mastoid pneumatisation and facial canal dehiscence were evaluated. Facial canal dehiscence was measured if it was found to be present.Results This study showed that facial canal dimensions decreased in pneumatised mastoids. Facial canal dimensions in females were smaller than in males. Facial canal dehiscence was detected in 5.9 per cent and 6.5 per cent of the patients on the right and left sides, respectively. No correlations were found between facial canal dehiscence and mastoid pneumatisation. The length of dehiscence was 1.92 ± 0.44 mm (range, 0.86-2.51 mm) on the left side. In older subjects, left facial canal dehiscence was detected more, and the length of the dehiscence increased.Conclusion This study concluded that during surgery, facial canal dehiscence should be kept in mind in order to avoid complications. © 2019 JLO (1984) Limited.
