Application of Human Amniotic Membrane in Temporomandibular Joint Osteoarthritis.

Human amniotic membrane (HAM) has recently been used as an interpositional material to prevent ankylosis or primary re-ankylosis after temporomandibular joint (TMJ) arthroplasty. Here, the authors describe an unusual case of a 32-year-old woman who presented with a noninflammatory degenerative osteoarthritis of the TMJ in which a HAM was placed following a high condylar arthroplasty and discectomy and show the clinicoradiological results. The procedure resulted in total pain relief and significant improvement in jaw movements. On the long-term follow-up computed tomography, complete remodeling of the glenoid fossa with formation of new ectopic bone was observed. While the application of a HAM can be an alternative procedure to prevent ankylosis when performing a discectomy and arthroplasty, this clinical report highlights the possibility that it can induce ectopic bone formation at this location.

Extragingival Pregnancy Pyogenic Granuloma on the Lip.

Pregnancy pyogenic granuloma is considered a benign common growth that usually develops on the gingiva in the second and third trimester of gestation, in response to local irritation, trauma or hormonal factors. Here, the authors report a case of a primigravida who presented an extragingival pyogenic granuloma with a rapid progression in the post-partum. The occurrence on the lower lip in the first few days after delivery was a relatively rarity in the present case which provoked a meaningful state of anxiety and cancerophobia to the female. Complete excision was curative and brought immediate relief of pain and discomfort. This clinical report highlights the possibility of pyogenic granuloma presenting like a rapid-growing mass on the lip and the importance of clinical differential diagnosis of such presentation in this atypical location.
