Evaluation of osteotomy accuracy and rotational and angular alignment for cranial closing wedge ostectomy performed with and without alignment aids.

Objective: To (1) investigate the use of K-wires as alignment aids for cranial closing wedge ostectomy (CCWO) and (2) evaluate their effect on osteotomy accuracy and angular/rotational alignment.

Study Design: Cadaveric study.

Animals: Cadaveric pelvic limbs (n = 20).

Expansile, inflammatory middle ear disease causing nasopharyngeal obstruction in a cat.

A 7-year-old, entire female, domestic shorthair cat presented with recurrent upper respiratory tract problems. Infectious otitis media caused expansion of the middle ear which ultimately resulted in complete obstruction of the nasopharynx. A ventral bulla osteotomy was successful in relieving the clinical signs.
