- Facial Surgery
- Preoperative medication: one hour before surgery while patient is still in his room.
- – Diazepam 5mg : oral or i.m.
- – Zofran 4mg (Ondansetron) : oral
- – Decadron 8mg (Dexametason) : Intravenous
- – Zinacef 1.5mg (Cefuroxim) : Intravenous
- – Iliadine (Oxymetazoline hydrochloride) nostril : 3 drops each
- – Emla cream (Lidocaine, Prilocaine) : on the nose and vestibular skin

- Patient monitoring: In the operating room, an ECG, pulse, respiratory, P0 and PC0 monitoring should be connected to the patient before any intraoperative sedation or local anaesthetic injection.
- Intraoperative sedation: Intravenous sedation is given before the use of any sprays, local injections or packs. Sedation: starts with:
- Dormicum (Midazolam) 2mg/IV
- Pethidine 30mg/IV
- Xylocaine spray 4% : two puffs in each nostril then wait for three minutes.
- Topical anaesthesia: Our aim is to eliminate pain and to achieve vasoconstriction. Xylocaine or Lidocaine 2% with 1:200,000 Epinephrine in 5cc syringe and 27 gauge needle is used. A series of bolus injections and infiltration are administered as follows:
- The anterior end of the inferior turbinate. (Fig. 3 – 4)
- Submucously, high under the nasal bones to the region of the anterior ethmoid nerve.
- Site of the caudal septum and transfixion incision. (Fig. 3 – 5)
- Site of intercartilagenous incision.
- Superior septal angle: the needle is passed through in the midline to the rhinion and up to nasion, a bolus is injected along each of these three sites.
- Site of the marginal incision at the mid lateral crus, then at one cm intervals along the caudal lateral crus.
- Bolus at mid-columellar between the two medial crus, then a bolus up between the domes and a bolus down at the base of the columella.
- Infiltrating along the nasofacial junction. The entry site is intranasally at the pyriform aperture, then the needle is pushed to a midpoint between the medial canthus and the nasion, then pulled while infiltrating. Care should be taken not to enter the angular vein.
- Bolus to the alar base at the nasolabial junction. The needle is pushed down to meet the bone then pulled while infiltrating.
- Bolus at the frenulum intraorally, behind the upper lip.
- One should
- the nose with local anaesthesia, 5cc is quite enough. Over infiltration causes swelling of tissue, leading to incorrect assessment such as false over projection, false hump, masking of depressions and mild deviations and widening the base of the nose. This will lead to over correction and later complications.
- Nasal anaesthetic pack: A light nasal pack soaked with Xylocaine gel, Prisoline and 5cc Xylocaine with 1:100,000 Adrenaline. The nasal cavity is packed in a way as to cover the regions of the sphenopalatine ganglion posteriorly, anterior ethmoid nerves under the nasal bones and the pack is made in layers to cover as much of the septum and inferior turbinates. Each pack is sutured to a long silk tie, the tie is fixed with plaster to the cheek. (Fig. 3 – 6)
- The procedure starts after fifteen minutes in order to allow time for vasoconstriction and amnesia. Once we start the procedure, the light nasal pack is pushed backward to close the posterior choana to prevent dripping of blood to the throat during surgery. The pack is fixed with a silk tie to the cheek to prevent the pack slipping into the oropharynx. The vestibular hair is trimmed at this stage.
- Maintaining the sedation: During the procedure, the sedation is maintained by one mg of Dormicum and ten mg of Pethidine every fifteen minutes. To reduce nausea, Zofran 4mg is given on continuous intravenous drip. The average time of our Septorhinoplasty is sixty minutes. Naloxon may be used for overdose.
- A trained Anaesthesiologist should be present and should stay at the head of the patient watching the ECG, P0 PC0 vital signs and the airways. Should the patient become agitated or uncooperative during the procedure, the Anaesthesiologist should be quite prepared to administer general anaesthesia. Nasal procedures under local anaesthesia should be carried out in a fully ready and equipped operating room.
