ABSTRACT
Objective: Increasing the nasolabial angle with nasal tip
rotation in tip surgery in rhinoplasty may cause the lower 1/3 of the face
to look longer. In particular, it can be perceived as an increase in upper
lip length. The aim of this study is to compare the effects of two types of
surgical techniques, that enhance tip rotation, on nasolabial angle; upper
lip projection and upper lip length. Material and Methods: Preoperative,
early postoperative and late postoperative photographs of 78 patients who
underwent rhinoplasty with application of tongue-in-groove or columellar
strut maneuvers were examined. The outcome measures were determined
as postoperative nasolabial angle, upper lip projection angle and
upper lip length, which were calculated in the computer program. Results:
Columellar strut was applied in 46 patients (59%), tongue in groove
was applied in 32 patients (41%). Nasolabial angle increased significantly
in both groups (p=0.01). In the both group, the upper lip length increased
significantly (p=0.01). The Z angle was found to be decreased in both
columellar strut and tongue-in-groove groups, inversely proportional to
the projection (3 and 4.8 degrees, respectively). Conclusion: Both columellar
strut and tongue in groove maneuvers are effective in increasing
the rotation. With these techniques applied in tip surgery, the length
and projection of the upper lip increases. It was found that, for each one
degree increment in nasolabial angle, the length of the upper lip increased
by 0.03 mm using the columellar strut technique and 0.04 mm using the
tongue-in-groove technique.
Keywords: Nasolabial angle; upper lip length; upper lip projection; columellar strut; tongue-in-groove
ÖZET
Amaç: Rinoplastide tip cerrahisinde nazal tip rotasyonuyla nazolabial
açının artırılması, yüz alt 1/3 bölümünün uzunluğunun artmış
olarak görünmesine sebep olabilmektedir. Özellikle de üst dudak uzunluğunda
bir artış olarak algılanabilmektedir. Çalışmanın amacı, tip rotasyonunu
artıran 2 tip cerrahisi tekniğinin nazolabial açıya, üst dudak
projeksiyonuna ve üst dudak uzunluğuna etkisini karşılaştırmaktır.
Gereç ve Yöntemler: “Tongue-in-groove” ya da kolumellar strut uygulanmış
olan 78 hastanın preoperatif, erken postoperatif ve geç postoperatif
fotoğrafları incelenerek nazolabial açı, üst dudak projeksiyon
açısı ve üst dudak uzunluğu olmak üzere 3 parametre bilgisayar programında
hesaplanmıştır. Bulgular: Kolumellar strut uygulanan hasta
sayısı 46 (%59), “tongue-in-groove” uygulanan hasta sayısı ise 32
(%41) idi. Nazolabial açı her 2 grupta da anlamlı derecede artış göstermiştir
(p=0,01). Her 2 grupta üst dudak uzunluğunu anlamlı olarak
artırmıştır (p=0,01). Üst dudak projeksiyonuyla ilişkili açı olan Z açısı,
projeksiyonla ters orantılı olarak kolumellar strut grubunda da “tonguein-
groove” grubunda da sırasıyla 3 ve 4,8 derece azalmış olarak saptanmıştır.
Sonuç: Hem kolumellar strut hem de “tongue-in-groove” tip
rotasyonunu artırmak için etkili manevralardır. Rinoplastide, tip cerrahisinde
uygulanan bu tekniklerle üst dudak uzunluğu ve projeksiyonu
artmaktadır. Nazolabial açının her bir derecelik artışında, üst dudak
uzunluğunun, kolumellar strut tekniğinde 0,03 mm, “tongue-in-groove”
tekniğinde 0,04 mm arttığı saptanmıştır.
Anahtar Kelimeler: Nazolabial açı; üst dudak uzunluğu; üst dudak projeksiyonu; kolumellar strut; tongue-in-groove
