Objectives:
In 1838, Edward Cock described the anatomic findings in 4 inner ears with a widely patent communication between the cochlea and the vestibule that is now frequently referred to as the “common cavity deformity” and is often confused with Michel's “otocyst deformity.” Little is known about the anatomic characteristics, including the presence of neural elements in this malformation.
Methods:
Light microscopy and 2-dimensional and computerized 3-dimensional reconstructions were used to determine the histopathology and spiral ganglion cell counts in 7 temporal bones with a widely patent cochleovestibular communication.
Results:
In all 7 specimens, the cochlea, vestibule, and semicircular canals were distinguishable and a bony defect resulting in an abnormal communication of perilymphatic space between the cochlea and vestibule was present. The ductus reuniens was abnormally wide in all. The cochlear duct varied from less than 1 turn to up to 2 turns. The mean spiral ganglion cells were estimated as a percentage of age-matched normal controls at 2.3%, 16.5%, and 26.8% when the cochlea was approximately 1, 1½, and 2 turns, respectively (p = .007). The cribrose area consisted of a thin membrane in 2 specimens, and Rosenthal's canal openly communicated with the cerebrospinal fluid space in 3 specimens. The stapes footplate was abnormal in all 7 specimens and consisted of a central defect bridged by a thin membrane in 4 specimens. The facial nerve was dehiscent in 5 specimens (71%) and also followed an anomalous course in 2 specimens (28%).
Conclusions:
The widely patent cochleovestibular communication is a distinct inner ear malformation, recognition of which may have important clinical implications. Estimates of spiral ganglion cells can be predicted from the number of cochlear turns. Although cochlear implantation is feasible in patients with this malformation, a higher risk of cerebrospinal fluid gushers, facial nerve injuries, meningitis, and poor performance would be predicted. A better understanding of the anatomy will allow more effective surgical planning and techniques and may have a significant impact in improving outcomes.

Connellsville Cultural Trust fosters the arts
2007
Connellsville residents Michael Edwards and Dan Cocks could see that Connellsville's once vibrant economy had slowed considerably, so they recently formed a cultural trust to help bring business and culture to Connellsville once again. \"Connellsville was the birthplace of Veterans Day,\" said Cocks, referring to Connellsville native Max Floto, who lobbied state legislators and then Congress to establish a day to honor the veterans of World War I. The Connellsville Cultural Trust was formed in June last year, with Edwards as president and Cocks as vice president. Its office is located in the former convent of Immaculate Conception Roman Catholic Church, Prospect Street.

More than meets the eye
2006
Businessman Michael Edwards and his partner, artist Dan Cocks, saw an opportunity for the people of Connellsville to take pride in their city once again by opening an art gallery in a rundown house on South Pittsburgh Street. \"There's a lot more to Connellsville than meets the eye, said Cocks, a self-taught stained-glass artist. Connellsville has many historical buildings and beautiful churches. I wanted to help unite the people of Connellsville in a common cause, to revitalize this town,\" he said. \"All the years that I was doing pottery, I was perfecting it. It was time for me to show my work. Edwards and Cocks came along and told me about the gallery,\" [Barbara Bailey] said. \"They asked me to display my work, so I did.\"

Couple Killed in Crash Neighbor charged with impaired driving
Police charged Michael A. Harry, 22, also of the 200 block of Brooklyn Avenue, with driving while impaired. Harry was released from jail yesterday after posting $250 bail, officials at First District Court in Hempstead said. The next hearing on his case is scheduled for tomorrow. According to Det. Sgt. William Cocks, Harry registered .06 on the breathalyzer test. Cocks said .05 is considered impaired, though .10 is considered legally drunk. The accident occurred at around 5:55 a.m. Police said Edward Spruill, 43, was traveling south on Brooklyn Avenue. At the intersection of Prospect Avenue in New Cassel, Spruill's car was struck by Harry, who was driving west on Prospect, according to police.
