Fetal Bovine Collagen Grafts for Repair of Tegmen Defects and Encephaloceles Via Middle Cranial Fossa Approach.

To evaluate the use of commercially available allogenic dural graft materials made of fetal bovine collagen, we present an analysis of our case series with use of autologous and allogenic graft materials. Patients who underwent surgical repair of a tegmen tympani defect associated with ipsilateral conductive hearing loss and cerebrospinal fluid (CSF) otorrhea using a middle cranial fossa (MCF) approach from 2004 to 2018 at Loyola University Medical Center were included. Resolution of CSF otorrhea, audiologic outcomes, facial nerve preservation, and surgical complications was analyzed. Thirty-three patients with an average age of 55.3 years (range: 21-78, standard deviation [SD]: 12.9) and body mass index of 34.4 (range: 22-51, SD: 7.4) underwent an MCF repair of a tegmen and dural defect. All patients presented with CSF otorrhea and conductive hearing loss ipsilateral to the defect. Repairs were made with combinations of allograft and autograft in 17 cases, allograft only in 15 cases, and autograft only in 5 cases. Improvement in hearing was noted in 33 cases, and resolution of CSF otorrhea was noted in 36 cases; one patient required repeat surgery which resolved CSF otorrhea. Three patients had minor complications; all these were in the autograft group. The MCF approach coupled with the use of fetal bovine collagen grafts is a safe and viable method to repair tegmen tympani and associated dural defects with salutary outcomes and low morbidity.

Older siblings are at increased risk for foreign bodies.

A prospective, case-control study was performed to describe the role that siblings play in foreign bodies of the head and neck and to recognize situations in which children are most at risk for foreign bodies. Any child or adolescent (0 to 17 years old) with a foreign body removed from the head or neck was included. The data collected included location of the foreign body, location of acquisition (e.g., home), and the number of and ages of siblings. Controls were matched by age, sex, and location of removal (clinic, operating room, or emergency department). Thirty-four patients were enrolled (20 male, 14 female). The average age was 5.25 years (range: 10 months to 15 years). The average age of patients with foreign bodies in the ear was 5.98 years (n = 23), esophagus 4.34 years (n = 6), and nose 2.97 years (n = 5). Nineteen (56%) of the foreign bodies were acquired at home and 17 (50%) under supervision by parents. Children with a younger sibling have a significantly increased risk of acquiring a foreign body compared with children without a younger sibling (odds ratio = 4.00, p = 0.04). We conclude that although acquisition of foreign bodies should become less common as children mature, older siblings (i.e., children who have a younger sibling) are at increased risk for foreign body acquisition. Most foreign bodies are acquired at home under supervision by parents. Increased awareness of this finding may help prevent foreign bodies in the head and neck.
