General anesthesia was administered with nasotracheal intubation. An infiltration 1.8 lidocaine with epinephrine 2% was carried out in the surgical field, then the surgical incision was drawn having previously performed trichotomy, asepsis and antisepsis of the surgical field and placement of sterile drape. A retroauricular approach ''E'' modified was performed Figure 3, taking in to account the measurements of Al-Kayat and Bramley to prevent facial nerve damage. A dissection was made to access the articular capsule with a ''T'' incision; a condylar retractor was placed behind the neck of the condyle to protect the maxillary artery during arthroplasty ATM remodeling.
Mediante anestesia general inhalatoria con intubación nasotraqueal a ciegas, se realizó infiltración anestésica de 1.8 mL de lidocaína con epinefrina al 2% en el espacio articular superior a intervenir; posteriormente se realizó marcaje de incisión quirúrgica previa tricotomía, asepsia y antisepsia de la zona quirúrgica y colocación de sterile drapee, realizando abordaje retroauricular modificado en ''E'', tomando en cuenta las mediciones realizadas por Al -Kayat y Bramley que proveen un rango suficiente de exposición y seguridad de no dañar las ramas terminales del nervio facial.
