Rhinoplasty Anesthesia

Rhinoplasty is performed under general anaesthesia. This is the standard approach for all rhinoplasty procedures performed by Dr Roth. This page explains what general anaesthesia involves, how it is administered, who is responsible for its conduct, and what patients can expect in the peri-operative period. It also addresses the role of local anaesthesia — which is used in addition to general anaesthesia in every rhinoplasty procedure — and explains why other forms of sedation are not appropriate for rhinoplasty.

General Anaesthesia — The Standard Approach for Rhinoplasty

General anaesthesia involves the administration of intravenous agents and inhaled anaesthetic gases to produce a controlled state of unconsciousness, during which the patient feels nothing, is not aware of their surroundings, and has no recall of the procedure. A breathing tube (endotracheal tube or supraglottic airway) is inserted after induction to protect the airway and deliver anaesthetic gases throughout the procedure.

Why General Anaesthesia is Used for Rhinoplasty

General anaesthesia is the appropriate choice for rhinoplasty for several important reasons:

• Airway protection: Rhinoplasty involves manipulation of the nose, often with some degree of controlled bleeding. Without a protected airway, blood from the operative field can drain posteriorly into the pharynx and be aspirated into the lungs. An endotracheal tube or supraglottic airway device prevents this. This is also why sedation-only anaesthesia without a secured airway is not appropriate for rhinoplasty.
• Controlled hypotension: A key component of modern rhinoplasty anaesthesia is the deliberate lowering of blood pressure to a carefully managed target during the procedure. Reduced blood pressure significantly decreases intra-operative bleeding, improves the clarity of the surgical field, reduces post-operative bruising, and allows more precise surgical work. This degree of blood pressure control is possible under general anaesthesia and is not achievable with sedation alone.
• Duration: Rhinoplasty typically takes two to four hours for primary cases, and longer for complex or revision procedures. Keeping a patient adequately sedated and comfortable for this duration without general anaesthesia is challenging and introduces risks of inadequate sedation depth, patient movement, and discomfort — all of which can compromise the surgical outcome.
• Patient experience: Under well-conducted general anaesthesia, the patient is completely unaware of the procedure and wakes with no memory of it. This is considerably more comfortable than sedation, in which patients may have some awareness, may feel occasional sensations, and may become restless or uncomfortable over a lengthy procedure.

The Anaesthetist

General anaesthesia for rhinoplasty is conducted by a specialist anaesthetist — a medical doctor who has completed specialist training in anaesthesia — working as a member of the surgical team. The anaesthetist meets with the patient prior to surgery, reviews the medical history and medications, assesses fitness for anaesthesia, discusses the anaesthetic plan, and monitors the patient continuously throughout the procedure. Any concerns about anaesthesia should be raised with the anaesthetist directly at the pre-operative assessment.

Before General Anaesthesia — Fasting

Patients must fast before general anaesthesia to reduce the risk of aspiration (inhalation of stomach contents during induction). The standard fasting requirements are:

• No solid food for at least six hours before surgery
• No milk or formula for at least six hours
• Clear fluids (water, apple juice, black tea or coffee without milk) up to two hours before surgery — your specific instructions will be confirmed by the hospital or day surgery the day before your procedure
• Regular medications should be taken as directed by your anaesthetist — do not assume all medications should be withheld

Local Anaesthesia — Used in Every Rhinoplasty

In addition to general anaesthesia, local anaesthetic agents are injected into the nose at the beginning of every rhinoplasty procedure. This is not an alternative to general anaesthesia — it is used alongside it and serves two specific purposes:

Vasoconstriction — Reducing Bleeding

Local anaesthetic solutions used in rhinoplasty typically contain adrenaline (epinephrine) — a vasoconstrictor that constricts the small blood vessels in the nose. When injected into the nasal tissues before dissection begins, adrenaline significantly reduces intra-operative bleeding by constricting the local capillary bed. This produces a clearer surgical field, reduces the risk of haematoma, and allows more precise surgical work. The combination of adrenaline-containing local anaesthetic and controlled hypotension under general anaesthesia produces the driest possible operative field for rhinoplasty.

Topical vasoconstrictors may also be applied to the nasal mucosa before surgery — typically cottonoids soaked in adrenaline solution — to further reduce mucosal bleeding during the procedure.

Post-Operative Pain Relief

The local anaesthetic component also provides immediate post-operative pain relief — the patient wakes from general anaesthesia with the nasal tissues still numbed, which reduces the degree of discomfort in the early recovery period. This wears off over several hours and is followed by mild to moderate discomfort that is typically manageable with paracetamol and the prescribed medications.

Why Sedation (Without General Anaesthesia) is Not Appropriate for Rhinoplasty

Intravenous sedation — sometimes called “twilight anaesthesia” or “conscious sedation” — involves the administration of sedative agents to produce a relaxed or semi-conscious state while the patient continues to breathe independently. It is used for many minor procedures but is not appropriate for rhinoplasty, for the following reasons:

• The airway is not protected — blood from the operative field can drain into the pharynx and be aspirated, with potentially serious consequences
• The degree of blood pressure control required for clean rhinoplasty surgery is not achievable
• The duration of rhinoplasty makes adequate sedation maintenance difficult — patients may become restless, uncomfortable, or move at critical moments during the procedure
• If unexpected complications arise or the scope of surgery needs to be extended, the anaesthetic cannot be readily deepened to the required level

All rhinoplasty procedures performed by Dr Roth are conducted under general anaesthesia at an accredited private hospital or day surgery facility. General anaesthesia for healthy patients undergoing rhinoplasty is a well-tolerated and safe procedure in experienced hands, and patients should not allow anxiety about the anaesthesia to delay seeking assessment for a nasal concern they wish to address.

Waking from Anaesthesia

At the end of the procedure, anaesthetic agents are gradually withdrawn, the airway device removed, and the patient allowed to wake in the recovery room under the care of recovery nursing staff. It is normal to feel disorientated, sleepy, or slightly nauseous in the immediate post-operative period. The nasal splint will be in place and the nose will feel congested. Pain is generally mild.

Most patients are transferred to the ward within thirty to sixty minutes of waking. For rhinoplasty, an overnight hospital stay is standard — patients are discharged the following morning after a review by Dr Roth. They must be accompanied home by a responsible adult and should not drive, operate machinery, or make significant decisions for twenty-four hours after general anaesthesia.

Risks of Anaesthesia

General anaesthesia in healthy patients is very safe, but all anaesthesia carries a small degree of risk. These include reactions to anaesthetic agents, nausea and vomiting in the post-operative period, sore throat from the airway device, dental injury, and, in a very small number of cases, serious adverse events. The anaesthetist will discuss the specific risks relevant to your health history at your pre-operative assessment. Patients with medical conditions affecting the cardiovascular, respiratory, or other systems, or those taking multiple medications, may require specific pre-operative assessment.
