Study Notes

Cosmetic Surgery Classifications

  • Glogau Classification: Evaluates skin aging based on wrinkles and surface texture.
  • Fitzpatrick Classification: Assesses skin tone and its reaction to UV exposure, important for determining skin types.
  • Dedo Classification: Categorizes based on the depth of skin layers affected.

Nasal Deformities and Conditions

  • Inverted V Deformity: Results from separation of upper lateral nasal cartilages; can arise from over-aggressive hump reduction or trauma.
  • Rhinophyma: Characterized by thickened, fibrous nose with prominent pores; linked to rosacea, not solely due to alcohol.
  • Coloboma: A congenital defect where there is a hole in eye structures; can affect vision based on severity.

Eyelid Conditions and Anatomy

  • Dermatochalasis: Excess skin on the eyelids, commonly seen in aging.
  • Epiblepharon: A congenital eyelid condition causing misdirected lashes; prevalent in Asian children.
  • Lagophthalmos: Inability to close eyelids; can result from surgical complications, nerve palsy, or skin disorders.
  • Marginal Reflex Distance (MRD): Distance measurement related to eyelid positioning; used in diagnosing ptosis and retraction.

Eyelid Glands

  • Glands of Zeis: Sebaceous glands at eyelash margins, secreting oils for lubrication.
  • Glands of Moll: Modified sweat glands at eyelash bases, contributing to tear film stability.
  • Krause’s Glands: Accessory lacrimal glands aiding in tear production, located in conjunctiva.
  • Ciaccio’s Glands: Lacrimal glands in the caruncle, also involved in tear secretion.

Surgical Techniques and Procedures

  • Mustarde Technique: A mattress suture technique for creating the antihelical fold during ear surgery.
  • Stenstrom Technique: Abrades cartilage to alter ear shape; considered unreliable.
  • Luckett Procedure: Single incision approach for creating an antihelical fold.
  • Furnas Suture: Involves suturing between concha and mastoid fascia for ear repositioning.

Ear Deformities

  • Stahl's Ear Deformity: Blepharoplasty deformity resembling Spock's ear, correctable by surgery.
  • Cryptotia: Condition where the helix of the ear is buried beneath the skin.
  • Question Mark Ear: Deformity in the supralobular area of the ear.

Tear Duct and Lacrimal System

  • Valve of Hasner: Membrane covering the nasolacrimal duct's nasal opening.
  • Aschner Reflex: Oculocardiac reflex affecting pulse rate; stimulated by traction on ocular muscles.

Facial Anatomy and Fat Pads

  • Retaining Ligaments of the Face: Support soft tissue; true ligaments anchor to bone, while false ligaments attach superficial fascia to deep fascia.
  • Fat Pads: Palpable fat tissues in eyelids, which can change with aging; separated by eye muscles.

Eyelid Surgery Preparation

  • Normal Eyelid Function: Requires a minimum of 20mm of intact skin; critical for blepharoplasty outcomes.
  • Incision Types: Different incisions (bird beak or Napoleon's hat) affect upper blepharoplasty based on planned procedures.

Additional Surgical Considerations

  • Innovative Techniques: Various techniques maintain or enhance ear and eyelid structure.
  • Granulomas and Suture Types: Braided sutures are more associated with granuloma formation post-surgery.

Common Conditions and Tests in Oculoplastic Surgery

  • Schirmer's Test: Evaluates tear production; negative result indicates normal tear function.
  • Pull Test: Assesses lower lid laxity; significant gap indicates the need for correction.

Normal Eye and Eyelid Functions

  • Bell's Phenomenon: Protective reflex of the eye during eyelid closure; can be compromised in certain conditions.
  • Afferent Pupillary Deficit: Symptoms of retrobulbar hematoma indicating serious complications.

Unique Facial Muscles

  • Facial Expression Muscles: Buccinator and Mentalis muscles have anterior innervation, distinct from other facial muscles.### Eyelid Edema and Blepharoplasty
  • Rare, recurrent episodic idiopathic eyelid edema primarily occurs in younger women.
  • Blepharoplasty may be considered once the condition resolves.

Grey Line

  • The grey line refers to a gap between the pretarsal tissue and the tarsal plate at the lid margin, marking the junction of skin and conjunctiva.

Blepharoptosis

  • Blepharoptosis is characterized by the drooping of the upper eyelid.

Apraclonidine

  • Apraclonidine is utilized for pharmacologic correction of lid ptosis that may arise from incorrect Botox injections, targeting sympathetically innervated smooth muscle.

Orbital Fat Pad

  • The pink lacrimal gland is identified as the orbital fat pad.

Sentinel Vein

  • The sentinel vein is associated with the temporal branch of the facial nerve; it represents a caution zone during surgical procedures.

Post-Operative Instructions for Blepharoplasty

  • Apply cold compresses immediately following surgery.
  • Maintain head elevation above the heart at all times.
  • Avoid lifting items over 10 pounds for a duration of 10 days.

Complications of Blepharoplasty

  • Hematoma: May result from breaching the septum leading to retroseptal hematoma. Treatment includes releasing blepharoplasty sutures for drainage and possible lateral canthotomy with cantholysis.
  • Lower Lid Retraction: Caused by excessive removal of anterior lamella (skin and/or muscle) or scar formation of the septum. Treatment involves massage, stretching, tarsal strip procedures, and potential grafts.
  • Lagophthalmos: Characterized by lid incompetence (2-3 mm) which isn't a primary concern immediately post-op. Management includes artificial tears and lubricating ointment, alongside correcting any underlying deficiency.

Modified Cottle Maneuver vs Cottle Maneuver

  • Modified Cottle Maneuver: Uses a nasal instrument to laterally displace cartilages to assess obstruction.
  • Cottle Maneuver: Involves lateral distraction of the cheek without instruments.

Bulbousness of Lower Lateral Cartilage

  • Cephalic trim can reduce bulbousness but requires preserving a minimum of 6 mm to prevent post-operative collapse.

Major Tip Supports for the Nose

  • The strength and direction of lower lateral cartilage.
  • The connection of medial crura to the inferior septal angle.
  • The attachment between lower and upper lateral cartilage.

Increasing Tip Rotation

  • Techniques include removing any dorsal hump, performing cephalic trim or shortening lateral crura, augmenting medial crura, and using premaxillary shield grafts.

Decreasing Tip Rotation

  • Options include rotating the caudal septum, shortening medial crura, or augmenting the dorsum.

Increasing Tip Projection

  • Achieved through transdomal or interdomal sutures, shield grafts, columellar strut grafts, or adjusting chin position.

Decreasing Tip Projection

  • Accomplished via complete transfixion incision, shortening the crura, lowering the septal angle, or modifying chin position.

Approaches to the Septum

  • Closed Approaches: Killian and Transfixion.
  • Open Approaches: External rhinoplasty and Lefort procedures.

Inferior Turbinate Hypertrophy and Nasal Obstruction

  • Management options include antihistamines, decongestants, topical steroids, or surgical solutions like turbinoplasty, submucosal resection, or radiofrequency ablation.

Radix Projection

  • Normal projection of the radix is 4-9 mm anterior to the cornea, with the nasofrontal angle typically at 120 degrees and vertical positioning aligned at the supratarsal crease.

Rhinion

  • The rhinion is the junction where the bony and cartilaginous sections of the dorsum meet; improper osteotomies may lead to nasal obstruction in this area.
