Drainage of an Acute Paronychia

For patients: a plain-language version of this topic is available. See the patient guide.
Overview¶
Drainage serves as a primary procedural intervention and component of the management strategy for acute paronychia [1]. The clinical approach is dictated by the stage of infection. Early-stage felons and paronychia may be managed with antibiotics alone [3]. In contrast, more advanced infections necessitate incision and drainage [3]. There is currently no consensus regarding the optimal surgical technique for treating acute paronychial abscesses [2].
Treatment generally requires a combination of surgical intervention, specifically incision and drainage, and appropriate antibiotic therapy tailored to the specific organism and infection severity [8]. For complicated paronychia, thorough excision is essential [5]. Empirical antibiotic therapy with amoxicillin–clavulanic acid is appropriate in these complicated cases [5]. Conversely, antibiotics are not required in the postoperative phase following excision of uncomplicated paronychia and felon in patients who are not at risk [6].
The Mini-Winograd Procedure and preoperative nail groove drainage represent valuable advancements in treating pyogenic paronychia with granulation proliferation, offering benefits regarding aesthetic outcomes, recurrence rates, and postoperative rehabilitation [15]. Despite these procedural nuances, large, prospective studies are needed to definitively identify the best treatment regimen for both acute and chronic paronychia [4].
Anatomy & Pathophysiology¶
Acute hand infections represent a diverse array of entities with potential for serious morbidity [13]. These infections are associated with a high rate of complications that are often difficult to manage [14]. Most hand infections result from neglected minor wounds [16]. Diagnosis is usually clinical, though imaging and laboratory evaluation aid in the process [17].
The distal phalanx possesses a dual blood supply [18]. Surgical procedures in the nail unit require knowledge of the surface, gross, and microscopic anatomy of the distal digit to minimize residual impact [27]. Proper direction of incisions helps ensure proper direction of healing, which determines whether scarring of the nail bed or matrix occurs [34].
Pediatric hands have unique characteristics including frequent exposure to oral environments, open growth plates, and robust circulation with fewer systemic comorbidities [28]. HIV infection increases the risk of developing a hand infection but does not increase the risk of revision surgery or ablation [38]. Many nail bed injuries are preventable, suggesting targeted prevention strategies should be considered [39].
Classification¶
General Classification: Acute paronychia is a type of hand infection [13]. Paronychia can be classified as acute or chronic [4].
Clinical Phenotype: Paronychia can be classified as purulent [5]. Paronychia can be complicated [5].
Clinical Presentation¶
Acute paronychia is characterized by the acute onset of pain, swelling, and erythema of the finger [19]. The finger pulp may become tense and painful, appearing pale to pink in sync with the patient's pulse [19]. The condition is associated with frank purulence [19].
Inspection may reveal nail dystrophy manifested by onycholysis, nail pain, and subungual hemorrhage [19]. Draining subungual abscesses may also be present [19]. A critical anatomical consideration is that paronychia can involve communication between the subungual abscess and the finger pulp, a space typically involved in an isolated felon [19].
Hand infections, including paronychia, represent a diverse array of entities with the potential for serious morbidity [13]. Atypical hand infections are difficult to recognize and treat due to their indolent nature and nonspecific symptoms [11]. Complications associated with mycobacterial hand infections can be significant [9]. In neonates, acute paronychia can be caused by clindamycin-resistant Staphylococcus aureus [22].
Investigations¶
Clinical Diagnosis: Hand and upper-extremity infections are usually a clinical diagnosis [17].
Laboratory: Imaging and laboratory evaluation aid in the diagnosis of hand and upper-extremity infections [17].
Plain radiography: Early osteomyelitis of the bone can be detected long before roentgenograms reveal evidence of destruction [29].
Treatment¶
Non-Operative¶
Evidence does not support conservative management as a standalone definitive treatment for acute paronychia requiring drainage; surgical intervention is required in conjunction with appropriate antibiotic therapy tailored to the specific organism and infection severity [8].
Operative¶
Surgical Approach / Technique: Drainage constitutes the primary procedural intervention for the management of acute paronychia [1]. For cases presenting with pyogenic paronychia and granulation proliferation, the Mini-Winograd Procedure combined with preoperative nail groove drainage serves as a specific therapeutic strategy [15].
Adjuncts: The Mini-Winograd Procedure and preoperative nail groove drainage strategy is recognized as a valuable advancement, offering improved aesthetic outcomes, reduced recurrence rates, and enhanced postoperative rehabilitation for pyogenic paronychia with granulation proliferation [15].
Complications¶
Other Considerations: Mycobacterial hand infections can result in significant complications [9]. Incision and drainage of herpetic whitlow with bacterial abscess resulted in no adverse sequelae at 3 years' follow-up [12].
Recovery¶
Early-stage felons and paronychia may be managed with antibiotics alone, whereas more advanced infections require incision and drainage [3]. In cases of complicated paronychia, thorough excision is essential [5].
Light activity (weeks): Evidence does not specify a week range for light activity or desk work.
Full activity (months): Evidence does not specify a month range for manual work or full range of motion return.
Complete recovery / outcome plateau (months): At 3 years' follow-up, there was no sign of adverse sequelae resulting from incision and drainage of herpetic whitlow with bacterial abscess [12]. At 3 years' follow-up, there was no recurrence of the herpes infection after incision and drainage of herpetic whitlow with bacterial abscess [12].
Rehabilitation protocol: The Mini-Winograd Procedure and preoperative nail groove drainage for pyogenic paronychia with granulation tissue is considered a valuable advancement in terms of aesthetic outcomes, recurrence, and postoperative rehabilitation [15].
Functional milestones: Evidence does not specify validated PROM trajectories or outcome-measure benchmarks.
Other Considerations: The Mini-Winograd Procedure and preoperative nail groove drainage for pyogenic paronychia with granulation tissue is considered a valuable advancement in terms of aesthetic outcomes, recurrence, and postoperative rehabilitation [15].
