Test on Secondary Cleft Deformities and Surgery

Question 1: The Pittsburgh fistula classification system indicates that Type I fistulas are often associated with noticeable clinical symptoms requiring immediate intervention.

A. Ano

B. Ne

Explanation: The study materials state that 'a type I fistula is of no perceivable clinical consequence,' meaning they are not typically associated with noticeable clinical symptoms or the need for immediate intervention.

Question 2: Which of the following is an advantage of using the facial artery myomucosal (FAMM) flap for palatal fistula closure, according to the study materials?

A. It is primarily used for large, recurrent fistulas in adults after local options have been exhausted.

B. Its design prevents damage to the facial nerve and Stensen’s duct.

C. It is ideal because of its long and large-caliber pedicle, lack of tissue bulk, and pliability.

D. It is based off the deep temporal artery, providing a thin flap with a reliable blood supply.

Explanation: The study materials state that the FAMM flap is advantageous as its design prevents damage to the facial nerve and Stensen’s duct. Other options describe characteristics of different flaps mentioned in the text (temporoparietal flap, radial forearm flap, or general statements not specific to the FAMM flap's stated advantages).

Question 3: Is an Abbé flap a primary treatment option for correcting a thick lip deformity that results from inadequate rotation advancement?

A. Ano

B. Ne

Explanation: The study materials state that if a thick lip results from a relative excess adjacent to an area of relative paucity (e.g., inadequate advancement rotation), the lateral lip element should be redistributed or readvanced. An Abbé flap is mentioned as a treatment for severe vermillion deficiency or significant abnormalities of the Cupid's bow when there is a paucity of healthy and unscarred tissue, particularly after bilateral cleft lip repair, not for a thick lip due to inadequate rotation advancement.

Question 4: According to the study materials, what is the primary role of columellar struts in nasal tip modification?

A. To narrow the nasal tip by reducing the distance between lateral tip defining points.

B. To support the nasal tip, often in conjunction with suture techniques.

C. To modify the curvature of the lateral crus and adjust nostril flare.

D. To adjust tip height by suturing the medial crura together.

Explanation: Columellar struts are supporting grafts specifically described as particularly helpful in supporting the nasal tip, and are often used in combination with tip-modifying suture techniques. The other options describe functions of transdomal sutures, lateral crural mattress sutures, and columellar septal sutures, respectively.

Question 5: Does the degree and stage of scarring in secondary cleft deformities influence the timing of intervention, dictating whether it should be early or late?

A. Ano

B. Ne

Explanation: The study materials explicitly state that 'The degree and stage of scarring will dictate an early versus late intervention.'
