Classical Needling:

"The Taiyang usually has much Blood and little Qi" (Su Wen 素問 ch. 24) implying this channel should normally be bled.
"The hand Yin and Yang receive their Qi via nearby paths so their Qi arrive swiftly. The depth of piercing must not exceed 2 fen and must not remain inserted for longer than one exhalation" (Ling Shu 靈樞 ch. 12).
"It is needled to a depth of three fen and is moxaed with three cones" (Huangfu Mi 皇甫謐, 3rd Century, Zhenjiu Jiayi Jing 針灸甲乙經).

Martial Applications & Effects of Injury:

Striking this point is said to cause the brain to shut down the body but being well protected by bone the usual result is only headache and tinnitus. Striking fractionally lower, at Tinghui GB-2, is considerably more damaging with nausea, dizziness and even potential death if struck hard (Montaigue, Dim Mak Locations, Taijiworld.com).

Notes:

Ling Shu Ch. 5 places this point, described as the "centre of the ear", as the end of of Shaoyang with Qiao Yin GB-44 as the root. In cases of where the joints become weak and the patient sways the whole channel is to be examined for surplus and deficiency and the pathology removed. Ting gui GB-2 might seem a more obvious location, being at the other end of the foot Shaoyang meridian but both arm and leg Shaoyang meridians meet at this location.

Ling Shu Ch. 52, On the Wei Qi, considers this to be the tip of the foot Shaoyang meridian with the root being at Zuqiaoyin GB-44.

Ling Shu Ch. 75, On Piercing to Regulate True and Evil Qi, recommends this point as part of the "To Redeem Out of Ignorance" treatment. This opening is pierced and an effect is observed in the pupils and a sound is heard in the ears. To hear the sound the patient is then supposed to press the two nostrils and close the mouth (Unschuld, 2016) or lie on his back (Wu & Wu, 2010). It is supposed to "remove what the eyes cannot see" and is compared to an enlightenment of the spirit.
