“…Some variants had been reported as case presentations or case series in the medical literature. These include cases of PAS with postauricular extension, [15] fistula opening below the intertragric notch, [16] and infraauricular sinus. [17] Three of the patients in the present study had preauricular skin tags, while two had nodular attachment around the sinus which were regarded as variants of PAS in this study.…”

Background: Preauricular sinus (PAS) is common among the blacks and it presents in different manners. The perceptions of adult patients with PAS may influence the management strategies deployed. Objectives: To determine the perceptions of adult patients who have PAS about the disorder and describe the modalities of presentation. Methods: A descriptive study was conducted at the ENT Clinics over nine months. Using a questionnaire, socio-demographic information, perception of patients on the cause, concerns, modality of treatment, inclination to surgery and perceived complications of surgery were explored. Examination findings of the sinuses, including results of audiological investigations were recorded. Results: The prevalence of PAS was 7.4% (56/754) and the mean age of the subjects was 43.9±10.6 years. Multiple causes of PAS were perceived by 58.5% of the patients, 13.2% were not concerned but intermittent symptom was experienced by 43.3% of the patients. More than half (52.8%) believed the sinus could be treated medically with drugs, 86.8% perceived complications from surgical excision while 73.6% abhorred surgical excision. Half of the PAS was in the left ear while 11.3% were bilateral. Audiological evaluation revealed 46.4% of patients had evidence of sensorineural hearing loss while 56.5% had abnormal middle ear functions. Conclusions: Some adult patients had wrong perceptions of PAS and most patients abhorred surgical excision. The clinical presentations were mostly of the classical type, with almost two-thirds violated. There may be a need for genetic studies on PAS in future research.

“…Following the traditional standard, the surgery must be performed after full control of the infection. 5 However, we found that the infection is hard to be effectively controlled by conventional infection treatment (giving antibiotics, repeated incision, drainage, etc), and such a process leads to a very long treatment period, increasing medical expenses and mental burden on patients. In most recently studies and clinical observations, more clinicians advocated that the preauricular fistulas resection surgery should be performed as early as possible, even along with the infection, to achieve a better prognosis.…”

Evaluating the treatment of infected preauricular fistulas by resecting the lesion combining with local flap repairing. Patients and Methods: This clinical study was implemented in Ningbo No. 1 Hospital and Wuhan No. 1 Hospital of China. We included 100 cases who were diagnosed with infected preauricular fistulas and needed further surgery treatment. Among them, 50 patients experienced the conventional treatment including a fully infection control following with a surgery to remove preauricular fistulas (conventional treatment group). Other 50 patients only took some simple pre-operation treatment for about 1-7 days, and then preauricular fistulas resection combining local flap repairing were performed regardless of the infection (local flap repairing group). The duration of total treatment procedure, healing index, and total cost were observed. Results: All patients were discharged at about 7 days after surgery, the duration of the postoperative period had no significant difference between groups. The total duration of treatment (from any first treatment time point to patient discharge) was only 13.98±2.14 days in the local flap treatment group compared with that of 43.06±8.24 days in the conventional treatment group. Further, the total cost of treatment per patient in the local flap repairing treatment group was about 47.1% of that in the conventional treatment group. Conclusion: For the treatment of infected preauricular fistula, performing a lesion removing surgery combining a local flap repairing can shorten the total treatment course, relieve patient's suffering, reduce treatment cost, and achieve a better clinical prognosis.
