Patient also complains of toothache since past 5 days. The swelling was sudden in onset and progressed to attain the present size. It was associated with breathing difficulty since past 1 day. It was also associated with pain over the region. She had difficulty in eating solid food due the restriction in mouth opening due to the swelling. She was on liquid diet since past 7 days. She was diagnosed with hypothyroidism and was on Tab. Thyroxine 50 mcg.

Examination of the head and neck revealed a diffuse swelling of size 10x10 cm over the right side of face extending from the right mastoid till the right oral commissure. Superiorly it extended up to 1 cm below right eye and inferiorly till the sternocleidomastoid origin.

Total leucocyte count of 5.59 thousand/mm3. After admission, antibiotics were started. Incision and drainage was planned for the patient.
