The treatment of whistling deformity in patients with cleft lip remains controversial. Previous reconstruction methods of whistling deformity have been limited in volume due to the necessity for primary closure of the donor site. This article presents a new method for secondary reconstruction of the vermilion deformity in patients with cleft lip. Our method is very simple and advantageous, in that primary closure after correction is not required. A rectangular mucosal flap is designed at the wet mucosal aspect of the upper lip. Inferiorly, this flap is based at the junction of the vermilion and mucosa, while the upper incision line should be at the buccal sulcus. This rectangular flap is advanced sagittally, and a labial thickness is reconstructed. Artificial dermis is grafted to the mucosal defect after flap advancement and mucosa regenerates secondarily. We applied this technique to secondary reconstruction in 32 patients with cleft lip between January 2001 and January 2005. Major complications (necrosis of mucosal flap and recurrence of whistling deformity) did not occur in any of the patients. Four patients required minor operations to reduce the volume. CONCLUSIONS: This rectangular mucosal flap with artificial dermis offers many advantages, including easy technique and minimal sacrifices. The combination of mucosal flap and artificial dermis prevents postoperative scar contracture and reduces the limitations of using the available volume of flap. We believe that this procedure is versatile and reliable not only for whistling deformity in cleft lip patients, but also for tissue defects of the lip resulting from other causes.

ABSTRACT: Objectives: The present prospective study aimed at objectively evaluating the relevance of a single horizontal Y-V vermilion plasty including orbicularis oris muscle repair for secondary correction of whistling deformities in unilateral as well as bilateral cleft lip cases.
Study Design: Ten patients were included in the study (mean age 20.2±6.2 years). The size of the whistling defects was determined on photographs before and 12 months after surgery. Additional surgical procedures like columella lengthening and rhinoplasty were documented.
Results: Seven minor and 3 moderate whistling defects were corrected. In 7 patients additional procedures were carried out. The data of the 12 months follow-up showed that the whistling defect was significantly reduced in size (p<0005). In 7 out of 10 patients the result of surgery was rated “good” and in 3 patients “moderate”.
Conclusions: The present prospective study is the first one to show on an objective basis that the presented technique allows reducing whistling deformities significantly with good overall results in the majority of the cases. Moreover, the technique can be combined with other corrective procedures like columella lengthening without problems. As a consequence, it is a relevant and universal surgical technique for the correction of whistling defects.

- "Niechajev  also reported lip enhancement using various alternatives including implants, autologous fat graft, and dermofat graft. Dermofat and autologous fat graft methods are simple and easy techniques, but these were less reliable because it is difficult to predict the degree of absorption and patients are at increased risk of developing an infection [16,17]. Wakami et al.  used the mucosal flap concomitantly with artificial dermis. "

ABSTRACT: The whistle deformity is one of the common sequelae of secondary cleft lip deformities. Santos reported using a crossed-denuded flap for primary cleft lip repair to prevent a vermilion notching. The authors modified this technique to correct the whistle deformity, calling their version the cross-muscle flap.
From May 2005 to January 2011, 14 secondary unilateral cleft lip patients were treated. All suffered from a whistle deformity, which is characterized by the deficiency of the central tubercle, notching in the upper lip, and bulging on the lateral segment. The mean age of the patients was 13.8 years and the mean follow-up period was 21.8 weeks. After elevation from the lateral vermilion and medial tubercle, two muscle flaps were crossed and turned over. The authors measured the three vertical heights and compared the two height ratios before and after surgery for evaluation of the postoperative results.
None of the patients had any notable complications and the whistle deformity was corrected in all cases. The vertical height ratios at the midline on the upper lip and the affected Cupid's bow point were increased (P<0.05). The motion of the upper lip was acceptable.
A cross muscle flap is simple and it leaves a minimal scar on the lip. We were able to reconstruct the whistle deformity in secondary unilateral cleft lip patients with a single state procedure using a cross-muscle flap.

ABSTRACT: Control of flow through a pipe requires mainly three devices, a
flow meter for the measurement of flow, a control valve to control the
flow and a controller. The controller gives appropriate signal to the
control valve, depending upon the difference between the actual flow
rate and the set flow rate. Conventional flow meters produce a
differential pressure in the flow, which is measured and suitably scaled
to get the flow rate. A relationship was established based on the
equation for control valve capacity (C<sub>v</sub>) for different valve
positions. An iterative approach is necessary in order to obtain a
particular flow rate. This necessitates the use of a computer or a
processor based system, similar to present day intelligent controllers,
to implement the scheme. A prototype was made in the laboratory using a
50 mm conventional control valve with pneumatic actuator working as the
control valve and flow meter. An HP data acquisition and control system
(DACS) was used as the controller. The signal for valve movement was
also provided from the DACS. The iterative computation of the flow rate
and appropriate setting of the same was done by the DACS. The
appropriate output signal is given by the DACS to the valve to achieve
the necessary now control. The unit was calibrated at the air flow
laboratory and an accuracy of ±1.5% was achieved for the same
