Background:
Flap techniques are acceptable for the surgical treatment of pilonidal sinuses. This study assessed a new modification of the rhomboid flap technique.
Methods:
The study included 133 patients with pilonidal disease who were treated between April 2004 and April 2009. The pilonidal sinus was removed with an oval excision, and an oval head rhomboid flap was prepared to reduce flap necrosis.
Results:
The mean age of the patients was 27.4 ± 4.6 years (range, 13-80). The rate of minor postoperative complications was 11.3%. The mean hospital stay was 2.3 ± .8 days (range, 1-6). The rate of recurrence was 1.5%. Regarding cosmetic results, 116 (87%) patients were very pleased, 15 (11.2%) were pleased, and 5 (3%) were displeased. The mean follow-up period was 22.5 ± 12.4 months (range, 5-57).
Conclusions:
The oval flap reconstruction method is a recommended procedure that produces fewer ischemic flaps with a low rate of recurrence and acceptable cosmesis.
Insights
This study introduces an oval flap modification for pilonidal sinus surgery, showing reduced complications and recurrence. Patients reported high satisfaction with cosmetic outcomes.
Area of Science:
- Surgical Innovation
- Plastic and Reconstructive Surgery
- Proctology
Background:
- Flap techniques are established for pilonidal sinus treatment.
- This study evaluates a novel modification of the rhomboid flap technique.
Purpose of the Study:
- To assess the efficacy of a modified rhomboid flap technique for pilonidal sinus treatment.
- To evaluate complication rates, recurrence, and cosmetic outcomes.
Main Methods:
- A cohort of 133 patients with pilonidal disease underwent treatment between April 2004 and April 2009.
- The pilonidal sinus was excised, and an oval head rhomboid flap was utilized to minimize flap necrosis.
Main Results:
- The mean patient age was 27.4 years.
- Minor postoperative complications occurred in 11.3% of patients.
- The recurrence rate was low at 1.5%, with 87% of patients highly satisfied with cosmetic results.
Conclusions:
- The oval flap reconstruction method is recommended for pilonidal sinus treatment.
- This technique results in fewer ischemic flaps.
- It offers a low recurrence rate and acceptable cosmetic results.
