Ipsilateral Hypertrophy of the Mastoid Process in Surgical Cases of Congenital Muscular Torticollis

The Cleft Palate-Craniofacial Journal, 2019
Objective: This study was to investigate ipsilateral hypertrophy of the mastoid process in the patients with congenital muscular torticollis (CMT). Design: Retrospective cross-sectional study. Patients: Children with CMT. Methods: A total of 212 surgical

Morphometric analysis of the mastoid process using cone beam computed tomography

European Journal of Anatomy
The sexual dimorphism of the mastoid process, as demonstrated by cone beam computed tomography (CBCT), is not well examined in forensic anthropology or clinical diagnostics. The mastoid region can be precisely imaged in three dimensions using CBCT, which

OSTEOMA OF THE MASTOID PROCESS [PDF]

Archives of Otolaryngology - Head and Neck Surgery, 1938
Of the bony tumors of the skull, those of the external auditory canal and of the accessory nasal sinuses are perhaps the most commonly encountered by the otolaryngologist. Osteoma of the mastoid process is infrequent in occurrence; Haymann1in 1919 was able to find but 8 authentic cases.

The mechanical impedance of the human mastoid process [PDF]

British Journal of Applied Physics, 1954
At the instance of the Electro-Acoustics Committee of the Medical Research Council, the National Physical Laboratory has undertaken a comprehensive series of measurements of the driving-point impedance of the mastoid process of the head on twenty normal subjects for a variety of operating conditions. The main object of the work was to develop objective

Population Differences in Cellularity of the Mastoid Process

Acta Oto-Laryngologica, 1979
Adult crania from four human skeletal population samples were radiographed in order to study variation of the air cell system in the mastoid process. Six types of processes were recognized, i.e., sclerotic, diploic, diplo-pneumatic, pneumatic, and highly pneumatic.

Secretory otitis and pneumatization of the mastoid process: Sexual differences in the size of mastoid cell system

American Journal of Otolaryngology, 1985
Seventy-nine children (41 girls and 38 boys) were subjected to tympanometry nine times from the age of 2 years to the age of 7 years. In addition, otoscopy was performed, and the children's otologic history was recorded. At the age of 7 years, roentgenograms were taken of the mastoid process, and the area of the air cell system was measured by ...

TRANSILLUMINATION OF THE MASTOID PROCESS AS AN AID TO DIAGNOSIS [PDF]

Journal of the American Medical Association, 1911
H. McA., aged 21, was admitted to Harper Hospital March 9, 1911. At 12 p. m. his temperature was 101.8 F., pulse 100, respiration 22. At 4 p. m. the temperature was 102.8 F., pulse 80. The patient complained of pain in the right ear. The temperature kept up until March 14, mostly about 99 and 100 F., with a tendency to diminish somewhat until March 20.

HEMANGIOMA OF THE EAR AND MASTOID PROCESS: Report of Two Cases [PDF]

Archives of Otolaryngology - Head and Neck Surgery, 1949
MOORE,1in his "Textbook of Pathology," described hemangiomas and divided them into three classes: hemartomatous hemangiomas, hemangioblastomas and sclerosing hemangiomas. In writing of the first group he described the pathogenesis as follows: ... If, during development, a small mass of vascular tissue is misplaced or distorted, it may persist as a ...
